Title: Tape driving mechanism of tape recorder
Inventor: FUKAWA KAZUMI
IPC: G11B15/30
Filed: 1979-11-22
Abstract: PURPOSE: To simplify the constitution of the tape driving mechansim of a tape recoder, by transmitting the action of the pinch roller support component directly to the idler operation component which supports the idler to trasmit the rotation to the reel drive disk.  
     CONSTITUTION: When the tape recorder is operated, the head base 1 works in coupling to the reproduction button to then shift to the solid-line position from the 2-dot chain line in the figure. The pinch roller support component 10 has a right turn according to the operation of the base 1, and the idlerworking lever 7 has a left turn. And the idler lever 6 starts a left turn. Both the major and minor diameter parts 5a and 5b of the idler 5 touch the flywheel 2 and the reel drive disk each as soon as the pinch roller 9 touches the capstan 3. As a result, a simultianeous start is given to both actions to give a fixed-speed travelling to the magnetic tape on both the roller 9 and capstan 3 and to take up the magnetic tape on the reel drive disk each.

Filed: 1981-09-24
Abstract: PURPOSE:To prevent occurrence of a drop down phenomenon in an engine speed at deceleration in idle operation, by controlling a throttle opening in accordance with a change of actual idle speed. CONSTITUTION:An arithmetic means 100 is constituted by an arithmetic unit 80, outputting a proportional value to a change of actual speed (a) in a range with output of the actual speed (a) from a speed sensor 30 at least a certain level higher than a target speed (b), and an arithmetic unit 40, comparing the actual speed (a), detected by the speed sensor 30, with the target speed (b) and outputting an integrated value of the deviation (c). Then at deceleration of an internal- combustion engine 10 after being raced, its actual speed (a) is dropped, however, the arithmetic unit 80 genetates an output value in proportion to the drop of the actual speed (a), and a target control position (e) rises to increase an actual control position (d) of a throttle stopper 20, thus opening of a throttle valve 11 is increased. As a result, a dropping speed of the actual speed (a) can be decreased.
