IPC: G11B33/02
Filed: 1981-12-21
Abstract: PURPOSE:To prevent an entry of dust and to facilitate the insertion of a cassette by providing an upper and lower couple of doors that open on hingers in the cassette insertion port in a front surface panel. CONSTITUTION:The front insertion doors 14 and 16 for a cassette 1 are closed and sliding pins 7 and 8 on both sides of a cassette storage body 4 are pressed by a spring 11 against reversely L-shaped horizontal parts of guide rails 9 and 10. As the insertion of the cassette is started, the upper and lower doors 14 and 16 come into contact with guide pawls 5 and 6 by being pressed by the cassette 1 and then the lower door 14 is pressed against the reverse surface of the cassette by a torsion spring. When the cassette 1 is further pressed in, the sliding pins 7 and 8 move along the guide rails 9 and 10 and are pressed against to reversely L-shaped vertical parts by a spring 11 to load the cassette 1. The torsion spring presses the lower door 11 against the reverse surface of the cassette 1 and the lower end of the upper door 14 against the stop surface of the cassette 1 to block an entrance 3. Therefore, an entry of dust is prevented and  the insertion of the cassette 1 is facilitated.

Abstract: PURPOSE:To aim at improvement in an exhaust characteristic over the whole car speed range, by altering a compensation value for feedback-controlling the air-fuel mixture supplied to a desired air-fuel ratio according to a car speed or a gearshift position of a transmission. CONSTITUTION:The exhaust content detected value detected by an oxygen sensor 15 is compared with the specified reference value at an electronic control unit 5, whereby proportional control and integration control compensating an air-fuel ratio in the mixture supplied by an internal-combustion engine for increase or decrease by compensation values PR and PL, both take place.
