摘要： PURPOSE:To make the temperature environment inside of a car comfortable by increasing thermal insulation efficiency and blocking radiation and provide such a ventilation thermal insulation system which prevents the temperature inside of the car from rising excessively even it is parked under the burning sun. CONSTITUTION:A series of an air flow passage a is formed between the outer plate 1 and the lining 2 of a door and/or side body, between double window glasses 4 and 5, and between the outer plate 6 and the lining 7 of a roof of an automobile. Or, the air flow passage a is formed between the outer plate 1 and the lining 2 and between the double window glasses 4 and 5. On the other hand, a front glass and a rear glass have the double structure in which air can flow so as to form a series of air flow passage b between the outer plate 6 and the lining 7. Air inside of the automobile is taken in by means of this air flow passage a and exhausted to the outside of the automobile through the roof or the double window glasses by means of the air flow passage a so as to perform ventilation thermal insulation.

摘要： PURPOSE:To enable stable driving of a vehicle at the time of acceleration by performing traction control in a simple system construction, in the case of a vehicle on which a continously variable transmission is mounted. CONSTITUTION:Driving force of an engine 1 is transmitted to drive wheels 22, 23 by means of a continously variable transmission equipped with a pulley 3 on the input side, a pulley 4 on the output side and a belt 5. In case when the driving wheels are slipped at the time of starting the vehicle or rapid acceleration, etc., a change ratio of the continuously variable transmission is varied to the speed change ratio wherein the dribing torque is reduced to such an extent as not causing any slip of the driving wheels, in a continuously variable transmission controller 10. Consequently, stability of the driving wheels can be secured.

摘要： PURPOSE:To improve the fuel consumption and drivability and suppress the internal noise or the like by shifting an engine to the low torque driving, generating a smaller torque, while transferring the gear ratio of an automatic transmission to the lower side, in the case where a torque variation in this internal combustion engine has become unfavorable. CONSTITUTION:An internal combustion engine transmits torque to each wheel via an automatic transmission and has a mechanism which provides a direct connection with transmitting route. In this case, when a variation in the torque has become unfavorable, the engine is shifted to the low torque driving, generating a smaller torque. At the same time, a gear ratio of the automatic transmission is transferred to the lower side. That is, at the time of lockup control, the torque variation is detected by a means 1. On the other hand, at the torque variation, it is controlled by a means 2 so as to lower the torque, while a portion of the lowered torque is made up for with the gear ratio. In addition, the engine controls an engine torque controller 5 consisting of a fuel injection valve 3 and a throttle controller 4 and a gear ratio control actuator 6 respectively.

摘要： PURPOSE:To reduce the shock at shifting by controlling a connecting/ disconnecting means so that a load device is in connection with the output shaft of an internal combustion engine when a control signal for shifting-up of an auto-transmission is given. CONSTITUTION:The rotational output placed out at the output shaft 101 of a car engine 1 is fed to an automatic transmission 2, and the output therefrom is transmitted to a drive wheel 6 through an actuator device 5, and the output on the output shaft 101 is further fed to a load device 4 through a clutch 3 for turning on the rotational load. In this automatic transmission 2 the gear shift is controlled with a shift control signal SP given out of a transmission control device 14 in accordance with the operating condition of the car or engine 1. When a shift control signal is given by the transmission control device 14, a load turnon signal LD is emitted at the same time, to transfer the clutch 3 from disengaged condition to the connected, and thus shock generated at gear shifting is absorbed.

摘要： PURPOSE:To keep stable switching and stable high speed chopper control even in the case of a load whose resistance changed considerably by making a power NMOSFET conductive and nonconductive not through a load. CONSTITUTION:An electric charge is supplied (charged) to a stray capacitor 24 in existence between a gate and a source of a power NMOSFET 11 not through a load 51. Thus, an event of an increase in a source level due to the existence of the load 51 is not caused and a gate voltage is not boosted over the voltage of a power supply 61, then the applied voltage between the gate and the source is ensured to make the drain and source of the power NMOSFET 11 conductive. Thus, even in a remarkable change in a load resistance or independently of the load resistor size, smooth and stable switching operation (load drive control) and high speed chopper control of the power NMOSFET are always attained.

摘要： PURPOSE:To easily and surely connect plastic optical fibers with a small connection loss by using a connector formed by putting a transparent adhesive agent into a connecting tube. CONSTITUTION:The low-viscosity adhesive agent or resin raw material is stably held in the joining tube 1 by enclosing the transparent adhesive agent 2 with films 3. The films 3 are ruptured by the insertion pressure of the fibers. The refractive index of the films 3 is equaled or approximated to the refractive index of the adhesive agent after curing to prevent the increase in scattering and absorbing even when the films remain. The cured film of the adhesive agent is effective and the loss is additionally decreased if the raw material resin of the core is used for the adhesive agent. The smooth insertion is assured if a discharge hole for the excess resin is provided near the joint part at the time of insertion. The intrusion of air bubbles is effectively prevented by finely drawing a part of the joint tube toward the center. The use of a heat-shrinkable tube is a good alternative. The adhesion by using the adhesive agent of a curing type by mixing is successively executed by partitioning the components by a film and rupturing the partition by insertion of the fibers.

摘要： PURPOSE:To easily read a recording pattern of a sticked label or a surface pattern by providing flexibility to an image sensor so as to push the sensor onto the surface of a body to be sensed having a curved face. CONSTITUTION:A flexible sensor board 21 is fixed onto a sensor support 2 deformed freely. The flexible hoard 21 is made of a plastic member such as a flexible printed board and an electrode 2111 of a photodiode 211 is imbedded in th surface. A transparent film 212 protects the photodiode 211 and secures the optical length of a thin film microlense array 213. Thus, even a label 11 sticked onto a body 1 to he checked having a curved face is read by pushing the flexible sensor board 21 simply and the simple, small sized and low-cost image sensor is obtained in comparison with a conventional sensor having a focus adjusting device.
