Abstract: A temperature distribution measuring instrument comprises an inner cylinder having slits and rotating around an infrared sensor, and a rotating outer cylinder having a plurality of slit blocks, each consisting of a plurality of slits. The slit blocks of the outer cylinder are arranged at intervals of a predetermined angle and shifted from one another by a predetermined height in a direction of the length of the outer cylinder, and infrared rays passing through a slit in the outer cylinder and a slit in the inner cylinder are converged at the infrared sensor.

Abstract: In a lighting control apparatus of a control panel in an automobile, a brightness reduction characteristic of a control panel lighting unit relative to a brightness signal of a brightness control unit is previously set according to external operation. The brightness control unit gives a brightness signal for controlling a luminosity of an instrument panel and a luminosity of a control panel which is provided near the instrument panel to a luminosity corresponding to an operation of a dimmer knob. When the brightness signal is given from the brightness control unit, the brightness of the control panel lighting unit is controlled according to a set brightness reduction characteristic relative to the brightness signal of the brightness control unit. Thereby, it is possible to make the luminosity of the control panel relative to the instrument panel a desired brightness characteristic.

Abstract: An automobile air-conditioner capable of controlling the displacement of a compressor in view of the traveling condition and air-conditioning condition of an automobile so as to maintain a pleasant feeling of the air-conditioning and an accelerating ability of the automobile in harmony with each other. The air-conditioner includes an air-conditioning preference judgment device by means of which a normal control of the air-conditioning operation is maintained when the judgment of this judgment means indicates the existence of an air-conditioning preference condition. The air-conditioning is performed in preference to acceleration of the automobile depending on the degree of acceleration of the automobile even when the automobile is accelerated.
