Focus onBusiness2Car Air-Conditioning CompressorApplying Unrivalled Technologies toCreate Revolutionary ProductsThe Car Air-Conditioning Compressor Business is a core business of the Automobile Segmentin addition to being an important strategic business of <strong>Toyota</strong> <strong>Industries</strong>. Drawing on a wealthof cutting-edge technologies, we effi ciently develop <strong>and</strong> manufacture high-quality productsthat are closely tailored to customer needs. By doing so, <strong>Toyota</strong> <strong>Industries</strong> is contributing toenhancements in comfort <strong>and</strong> technological advances of vehicles manufactured not only by<strong>Toyota</strong> Motor <strong>Corporation</strong> but the world’s other top-name automakers as well.26 <strong>Toyota</strong> <strong>Industries</strong> <strong>Corporation</strong> Annual Report 2006
Breakthrough <strong>Innovation</strong>s <strong>and</strong> Cutting-EdgeCompressors for Hybrid Vehicles<strong>Toyota</strong> <strong>Industries</strong>’ car air-conditioning compressors are notedfor unsurpassed quality <strong>and</strong> reliability, attributes that havewon extensive acclaim from <strong>Toyota</strong> Motor <strong>Corporation</strong>(TMC) <strong>and</strong> other leading automakers. As testimony to ourunsurpassed technological development capabilities, our CarAir-Conditioning Compressor Business has solidly establishedits competitive superiority in the industry.This business has a proven track record in consistentlydeveloping new epoch-making products that continuallyforesee evolving market needs, <strong>and</strong> in turn, stimulate furthertechnological innovation of automakers. As prime examples,in the 1960s we developed Japan’s fi rst swash-platecompressor, while in the 1980s we developed a compact,lightweight 10-cylinder swash-plate fi xed-displacementcompressor noted for its outst<strong>and</strong>ing reliability at highoperating speeds. We followed this accomplishment inthe 1990s by responding to growing concerns aboutthe environment with the development of an internallycontrolled one-way swash-plate variable-displacementcompressor that reduces the load on the engine to raisefuel effi ciency. Building on this momentum, in the late 1990s<strong>Toyota</strong> <strong>Industries</strong> unveiled an externally controlled continuousvariable-displacement clutchless compressor that enhancesacceleration <strong>and</strong> reduces energy consumption by sensingchanges in the external environment, such as engineacceleration. Demonstrating a dedicated commitment tocombating such environmental problems as destruction ofthe earth’s ozone layer <strong>and</strong> global warming, in 2002 <strong>Toyota</strong><strong>Industries</strong> <strong>and</strong> DENSO <strong>Corporation</strong> (DENSO) developed anelectrically driven compressor for fuel-cell hybrid vehicles thatuses CO2 as a substitute refrigerant for hydrofl uorocarbons.Also in collaboration with DENSO, in 2003 we developed atwo-way compressor with a built-in motor for hybrid vehicles<strong>and</strong> an electrically driven compressor for hybrid vehicles.The two-way compressor is driven alternately by the engineduring driving <strong>and</strong> by a built-in motor during engine stop,while the electrically driven compressor realizes an optimalbalance between fuel effi ciency <strong>and</strong> comfort since the carair conditioner can remain turned on even during enginestop. Each of these pioneering compressors was developed<strong>and</strong> commercialized ahead of our competitors, offeringfurther evidence of our technological <strong>and</strong> competitivesuperiority.At the Forefront of the Market with SuperbTechnological CapabilitiesIn fi scal 2006, <strong>Toyota</strong> <strong>Industries</strong>’ total global production<strong>and</strong> sales of car air-conditioning compressors amountedto 19.1 million units, giving us the top share of the globalmarket. In the Japanese market, we sold approximately5.5 million compressors to TMC <strong>and</strong> other principaldomestic automakers, which made us the market leader.Automobile Trends <strong>and</strong> <strong>Toyota</strong> <strong>Industries</strong>’ Product Development1980s 1990s 2000sAutomobiletrendsProvide higher engine performance <strong>and</strong> comfortable interiorReduce ozone layer destructionImprove gas mileageHybrid cars, fuel-cell hybrid vehiclesSlow down global warming<strong>Toyota</strong><strong>Industries</strong>’productdevelopmentFixeddisplacementtypeUse of HFC-134a refrigerant1981Compact, lightweight10-cylinder swash-plate compressor*Variabledisplacementtype1995Power efficient,superb drivability7-cylinder one-wayswash-plate compressor*2003 Rotary valve-type compressorRotary valve-type variable-displacement compressor*Externally controlled, variable displacement, clutchless type1997Ultra-lightweight, ultra-power efficient, superb drivability6-cylinder one-way swash-plate compressor*2002 CO2 compressorCFC-freeCO2 compressor for fuel-cell hybrid vehicles*2003Electrically driven compressorCompact, lightweight, highly efficientElectrically driven compressor for hybrid vehicles** World’s first commercial products2003 Two-way compressorTwo-way compressor for hybrid vehicles*<strong>Toyota</strong> <strong>Industries</strong> <strong>Corporation</strong> Annual Report 200627
