    摘要: There is disclosed a fuel cell cooling plate for eliminating waste heat generated by operation of a fuel cell. The cooling plate consists of an inner substrate layer composed of a soft, deformable plastic or low elastic carbonaceous material, sandwiched between outer substrate layers of a strong gas-impermeable carbonaceous material, and a sealing material. The inner substrate is chased with grooves, which house metal cooling pipes for passage of the cooling medium. The soft, deformable, plastic or low elastic material of the inner substrate can be formed so that the grooves fit tightly around the cooling pipes, preventing formation of any air gaps between the pipes and the grooves. This permits nearly complete circumferential contact between the pipes and the grooves, thereby reducing thermal resistance associated with air gaps, and maintaining a high degree of heat transfer. Further, the plastic or low elastic material of the inner substrate layer can conform to thermal expansion and contraction of the cooling plate and pipes, reducing excessive wear over the lifetime of the cooling plate.

    摘要: An electronic control apparatus for use in vehicles comprised of two, one-chip microcomputers. The microcomputers each have a ROM and a RAM and are used to control different systems provided in the vehicle. The ROM of the second microcomputer stores an operational program which can be used to calculate control values for controlling various types of devices. It also stores operational map data which can be used to calculate control values for controlling various types of devices. Various signals output by the sensors provided in the vehicle are supplied to both microcomputers. At the start of the power supply to the apparatus, the operational map data stored in the ROM of the first microcomputer, which is to be used by the second microcomputer, is transferred to the RAM of the second microcomputer. The second microcomputer calculates a control value from the transferred operational map data, the signals output by the sensors and other data, thereby controlling the system assigned to it.
