Abstract: First and second refrigerating circuits respectively cause first and second adsorbing bodies to alternately adsorb and release first and second coolants. In the first refrigerating circuit, when the first adsorbing body is heated, it releases the first coolant. The released first coolant is cooled, and discharged through an expansion valve so that a part of the first coolant is liquefied. The resultant latent heat of vaporization can be utilized to cool an object to be cooled. Thereafter, the first coolant is adsorbed when the first adsorbing body is cooled. In the second refrigerating circuit, when the second adsorbing body is heated, it releases the second coolant. The released second coolant is cooled by a liquefied-gas-type cooler, and discharged through an expansion valve so that a part of the second coolant is liquefied. The resultant latent heat of vaporization is utilized to cool the first adsorbing body of the first refrigerating circuit.

Abstract: A vehicle has a rotary magnetic field member which is rotatably supported at a position near the surface of a roadway along which the vehicle runs and rotatingly driven by a driving device.

Abstract: In a hybrid vehicle in which the front or rear set of wheels is driven by an engine (7) and the other set of wheels is driven by a motor (8), a traveling mode deciding unit (4) is provided with a table for deciding engine throttle opening and motor output, with driving force being distributed in accordance with the engine throttle opening and motor output decided by referring to the table. The table decides the traveling mode based on signals from a detector (2) which detects the remaining life of a battery, a vehicle velocity sensor (1) and an accelerator opening sensor (3). By deciding the traveling mode using such a table, it is possible to distribute driving efficiently in dependence upon the remaining life of the battery.

Abstract: A first external storage device which may be a CD stores data representing standard map of a particular area and that required for guidance, and a second external storage device which may be an IC card stores individual data which cannot be complemented by said data representing the standard map and said guidance data. Since the data is stored in both CD and IC card, the number of data can be reduced. This makes the operation simpler and enables a data that meets the demand of a user to be selectively supplied to the user. In consequence, guided navigation is made possible from any starting point to a destination, and data updating can be made relatively easy.

Abstract: A transmission control system for controlling a transmission. The system has a main transmission with a speed changing mechanism and an output shaft, a substransmission connected to the output shaft, and a control system for receiving outputs from a number of sensors which sense the running state of the vehicle.
