  • Patent number: 6581022
    Abstract: A control unit takes in a set temperature, a vehicle-internal temperature, an ambient temperature, an engine-water temperature, a sun load and a vehicle speed from a means for setting a temperature of the air inside a vehicle and sensors. The control unit determines whether a failure has occurred in the internal-air-temperature sensor and the external air temperature sensor. If a failure is determined in any of the sensors, the control unit fetches a substitute value registered in advance in the substitute-value table. Then, the outlet temperature as well as the difference between the vehicle-internal temperature and the set temperature are determined from the signals generated by the sensors. A driving voltage of the FAN motor and switching position of the outlet flap are subsequently computed. If a failure in either of the internal-air-temperature sensor and the external air temperature sensor is determined, an opening of the air-mix flaps is then set.

  • Publication number: 20010020221
    Abstract: A control unit takes in a set temperature, a vehicle-internal temperature, an ambient temperature, an engine-water temperature, an sun load and a vehicle speed from a means for setting a temperature of the air inside a vehicle and sensors (S1). The control unit determines whether a failure has occurred in the internal-air-temperature sensor and the external air temperature sensor respectively (S2, S3). If a failure is determined in any of the sensors, the control unit fetches a substitute value registered in advance in the substitute-value table (S10, S11). Then, the flow of the procedure goes on to a step S4 and an outlet temperature and as well as a difference between the vehicle-internal temperature and the set temperature are found from the signals generated by the sensors, and a driving voltage of the FAN motor and switching position of the outlet flap is computed (S5, S6).

  • Patent number: 5665464
    Abstract: A carbon fiber-reinforced carbon composite material is disclosed which includes a matrix of carbon and unidirectionally oriented carbon fibers dispersed in the matrix, wherein the content of the carbon fibers is at least 50% based on the volume of the composite material, wherein the volume of pores having a pore diameter of 10 .mu.m or more is not greater than 5% of the total pore volume of the composite material, and wherein at least 90% of the total pore volume is the volume of open pores. The composite material is obtained by impregnating carbon fibers with a dispersion having a viscosity of 5-50 cP at 25.degree. C. and containing carbonaceous powder with an average particle diameter of smaller than 0.5 .mu.m in an organic solvent solution of a thermosetting resin. After unidirectionally aligning the carbon fibers, the impregnated fibers are molded and cured and then calcined.

  • Patent number: 5661744
    Abstract: An excimer laser beam irradiation apparatus capable of processing a workpiece optimally with an excimer irradiation beam even when intensity distribution of the excimer laser beam undergone multiple reflections is non-uniform. A patterning mask has light-transmissive portions for allowing the excimer laser beam to pass through and a reflecting layer for reflecting it. A high reflectivity mirror disposed in opposition to the reflecting layer reflects the excimer laser beam reflected from the reflecting layer toward the patterning mask. An imaging lens images a pattern of the excimer laser beam transmitted through the patterning mask onto a workpiece for irradiation thereof. A workpiece moving mechanism and a mask moving mechanism move the workpiece and the mask moving mechanism, respectively.

  • Patent number: 5395607
    Abstract: The pitch based carbon fiber has a uniform crystal structure in which substantially all crystal fibriles constituting the fiber have the thickness ranging from 30 to 200% of the average thickness Lav. Uniform stress distribution over uniform crystal fibriles can be obtained. This permits suppresion of non-linearity of the compressive modulus of elasticity of carbon fiber to greatly improve the compressive strength thereof. Typically, a compressive strength of 100 to 170 kg/mm.sup.2 can be obtained with a tensile modulus of elasticity of 50 ton/mm.sup.2. Such carbon fiber can be obtained by securing uniformity of molecular weight distribution of the liquid crystal pitch and also uniformity of the orientation of the liquid crystal constituent molecules by the application of multi-stage high shear spinning.
