Sales in Thermal Systems surged 26.1% to ¥870,676 million. This increase was primarily due to the effects of a change in the fiscal year-ends at overseas sub-sidiaries. The change caused 15 months of sales at these subsidiaries to be included in the year's results, raising sales in this segment by 15.4%. During the year, DENSO Thermal Systems S.p.A. became a consolidated subsidiary, accounting for 5.7% of the increase. The effects of a weakening yen raised sales by 4.6%, while orders for thermal systems for new models such as the Toyota Yaris in Europe also contributed to the rise.
Main Products
· Climate Control Products:
Air conditioners for cars, buses, and construction equipment
· Powertrain Cooling System Components:
Radiators, cooling fans, inter-coolers, oil coolers, integrated cooling modules
Car air-conditioning systems account for over 80% of sales in Thermal Systems. DENSO car air-conditioning systems have consistently held the top spot in the global market since 1990, and now boast a market share of around 24%. Europe, Asia, and South America, regions where car air conditioner use is still relatively low, are target markets. We see particular potential in Europe, establishing and enhancing manufacturing facilities in the Czech Republic and Italy in the year ended March 2002, to meet an anticipated increase in demand. During the period, DENSO made further progress in developing innovative and unique air-conditioning products—systems that consume less of the engine's power, are more compact, are highly functional, and use non-fluorocarbon refrigerants.

Sales in Powertrain Control Systems climbed 24.3% to ¥500,892 million. An additional three months of sales at overseas affiliates, owing to the change in their fiscal year-ends, caused sales to rise 9.9%. The effects of a weaker yen also gave a 3.9% boost to sales. In North America, developments such as full-scale local production of stick coils, stronger sales of exhaust gas sensors and injectors, and the start of production of integrated air/fuel modules all helped to expand sales. Common rail systems were another strong performer. Sales of these systems jumped from 96,000 units in the year ended March 2001, to 283,000 units in the year under review.
Main Products
· Diesel Engine-Related Products:
Fuel injection systems and components
· Gasoline Engine-Related Products:

The Powertrain Control Systems Business develops and manufactures a wide variety of systems and products for both diesel and gasoline powertrains. The product lineup encompasses the whole powertrain process, from air induction through combustion and exhaust. Many products are contenders for first or second global market share in their categories. Fuel pumps, exhaust gas sensors, variable valve timing (VVT) units, and ignition coils are just some of the DENSO powertrain products that have consistently held leading global market shares. Looking ahead, the group is targeting the further development of gasoline direct injection and common rail systems to improve fuel efficiency and meet tougher emission regulations, as well as expand sales of these products. Moreover, the group will strengthen its supply structure, introduce new marketing technologies, and enhance its application engineering functions. These actions will create a support framework capable of rapidly responding to the demands of automobile manufacturers.

Sales in the Electronic Systems Business jumped 15.5% to ¥410,067 million. An additional three months of sales at overseas subsidiaries caused sales to increase 8.4%.The effects of the weak yen added another 3.6% to the figure. Healthy sales of instrument clusters, demand for DENSO's engine ECUs with enhanced functions, and success in expanding sales to customers in Europe such as Volvo and Jaguar, all contributed to the overall rise in sales. Car navigation systems were particularly impressive per-formers during the year under review. The number of units sold in the year ended March 2002 surged to 414,000, up from 243,000 in the previous period.
Main Products

· Electronic Components and Devices:
Engine ECUs, hybrid ICs, sensors
As cars are equipped with more sophisticated electronic systems, component manufacturers have to clear higher technical hurdles. DENSO is now required to develop electronic devices such as semiconductors and sensors, and create highly accurate, complex control system technology. In its Electronics Systems Business, DENSO not only has the in-house technological expertise to develop semiconductor products, but also the know-how and resources in software development to meet the needs of individual customers. The ITS field is one example of these all-round strengths. Here, we are involved in development across the board, from component hardware through application software and infrastructure.

Sales in the Electric Systems Business grew 15.1% to ¥288,004 million. This was primarily due to changes in the fiscal year-ends at overseas subsidiaries and the effects of the weak yen, which accounted for 10.7% and 4.3% of the rise, respectively.
Main Products
· Starters and Alternators
· Components for hybrid electric vehicles (HEVs):
Integrated starter generators (ISGs), DC-DC converters, battery ECUs, oil pump motors, inverters and electrical current sensors
· Driving Control and Safety Products:
Airbag sensors and ECUs, anti-lock brake control system (ABS) actuators
With the shift to smaller, lighter, and more functional alternators and starters, progress is being made on standardization. This approach is also helping the Electric Systems Business to enhance cost competitiveness. In components for HEVs, DENSO developed and commercialized ISGs and a number of other products for different types of HEV systems. DENSO is leading the industry in this field in product development. In components for car safety systems, we are gearing up development of next-generation airbag sensors and ECUs to better protect occupants in the event of a collision. These efforts go hand in hand with DENSO's continuing development of safety systems.
Highlights of the Year
· Development and commercialization of an ISG and oil pump motor for the Toyota Estima HEV
· Development and commercialization of an ISG, ECU integrated inverter, and magnetic clutch for the Toyota Crown Mild HEV
· Development and commercialization of a side impact sensor (SIS) for airbag systems, less than half the size of previous components
DENSO's small motors business increased sales by 6.9% to ¥167,460 million. Falling automobile sales, overall, in the North, Central, and South American markets led to a 3.4% decline in sales. This was offset by the effect of accounting changes at overseas subsidiaries and the weaker yen, contributing increases of 6.8% and 3.1%, respectively, to the sales growth.
Main Products
Windshield washer and windshield wiper systems, power window motors, other motors
DENSO's small motors are manufactured by group company ASMO Co., Ltd. ASMO's power window motors and washer motors boast leading global market shares in their respective product categories. DENSO is working to maintain its market-leading cost competitiveness in small motors and strengthen its overseas manufacturing network. Moreover, we are accelerating the development of light, highly efficient motors for emission control and fuel saving systems.
Highlights of the Year
· Start of production of small motors in Italy
· Development and commercialization of a convertible roof motor system

With DENSO's shift of focus from its core cellular phone products to telematics, the telecommunications business is currently going through a phase of contraction. This was reflected in the division's performance during the year ended March 2002, with sales decreasing 10.1% to ¥79,010 million.
Main Products
Cellular Phones
During the year, DENSO withdrew from the cellular phone manufacturing business. Despite this move, we still see mobile communications as a vital area, and will continue research into this technology to keep pace with the car's increasing integration into information networks.
Falling demand from overseas markets for industrial systems products was offset by new product launches and efforts to boost sales in the domestic market. These steps led to a rise in sales. In environmental systems, sales of DENSO's CO2 refrigerant heat-pump water heater for household use beat expectations. As a result, combined sales in industrial and environmental systems rose 11.6% year on year to ¥62,427 million.
Main Products
· Automatic ID Data Capture Devices:
Bar code handy scanners and terminals, QR code handy scanners and terminals, non-contact IC cards, security systems
