Abstract: PURPOSE:To prevent reception disturbance with an infrared ray emitted by itself by combining plural sets of light emitting elements and light receiving elements whose emission angle characteristics differ from each other so as to adjust a light distribution characteristic thereby obtaining a desired communication available range. CONSTITUTION:Inter-on-road vehicle communication is executed between an on-road device 1 and an on-vehicle device 6. A light emitting and light receiving device 4 having a light emitting section and a light receiving section of the on-road device 1 is fitted to an arm 3 stretched on a road so as to be correspondent to a drive track 5, and a controller 2 allows the light emitting section to emit an infrared pulse ray onto a road face. On the other hand, the on-vehicle device 6 is mounted with a light receiving and a light emitting device 7 having a light emitting section and a light receiving section and with a controller 8. The light emitting section of the light emitting device 4 on the road side is made up of the combination of plural light emitting elements and emits an infrared pulse ray having a light distribution pattern covering only required tracks. That is, the light emitting elements and the light receiving elements with a narrow emission angle are arranged around the light receiving elements having 2 wide light, emitting angle to obtain the directivity covering a desired range, then the limited range is easily covered.

Title: Vehicle running control device
Inventor: IMAI YASUO
IPC: B60W30/00
Filed: 1993-11-09
Abstract: PURPOSE:To maintain smooth follow-up running even when a preceding car is temporarily lost, in a vehicle running control device to perform follow-up running as an intercar distance between a can and a preceding car is maintained. CONSTITUTION:An intercar distance sensor 10, a car speed sensor 12, a handle steering angle sensor 14, a throttle opening sensor 16, and a set switch 18 are mounted on a car and detecting signals therefrom are outputted to an ECU 20. From steering angle data, it is detected by the ECU 20 that a vehicle runs at a curve road. When intercar distance data is rapidly increased discontinuously and a preceding car is lost, control of follow up to a different preceding car is delayed by a given time. When right a preceding car is caught again, after transfer to original follow-up control, a throttle actuator 22 or a brake actuator 24 is controlled. Since follow-up control is delayed for a given time, smooth follow-up control is practicable without rapidly approaching the lost original preceding car.

Abstract: PURPOSE:To miniaturize a condenser as a result of effectively absorbing and condensing the working fluid gas constituent by an absorbing medium by providing a heat exchanger to cool the fluid separated by a gas-fluid separator by means of a low temperature heat source. CONSTITUTION:After the heat of the working fluid 21 at the exit of a turbine 1 is recovered with an exhaust heat reclaimer 2, the working fluid 21 is effectively absorbed and condensed through a condenser 3 into a low concentrated aqueous ammonia which is an absorbing medium sufficiently cooled in advance through a heat exchanger 6. The absorbing medium condensed by the condenser 3 is pressurized with a pump 4 and its temperature is raised with the exhaust heat reclaimer 2 to become a mixture of gas and fluid. The mixture of gas and fluid runs into a gas-fluid separator 5 where it is separated into a fluid phase, implying the absorbing medium 22, and a gaseous phase. The high concentrated ammonia vapor, which is in the gaseous phase, is mixed with some of the condensed fluid at the exit of the condenser 3 to make the working fluid 21. This working fluid 21 is cooled and condensed through the condenser 7 and recirculated by a fluid supplying pump 8.
