CONSTITUTION: When a person sits on a seat part 23, the load is divided to working point parts in the front and rear of the turning shaft 24 (fulcrum part) of a balance member 22, and since the balance portion is offset by the balancing action, the clockwise moment which is the unbalance portion is relatively small. When a seat back 25 is fallen backward, the tip end side of the member 22 is rotated upwards around the shaft 24, an L-shaped link 27 is turned upward to the left around a shaft 28 thereby. Namely, the link piece connecting the shaft 28 and shaft 29 of the L-shaped link 27 is turned from a standing position to a position slightly inclined forward. Thus, the seat part 23 is moved forward according to the turn of the L-shaped link 27. At that time, the front part side of the seat part 23 is slightly lowered.

Filed: 1984-09-14
Abstract: PURPOSE:To eliminate the high frequency component of a jitter to which the mechanical system of a tangential servo cannot response by setting the cut-off frequency of a loop filter inserted in the loop of a read clock generation PLL circuit lower than the maximum frequency of the band of the tangential servo loop. CONSTITUTION:Since the mechanical system such as an actuator drive device or the like cannot sufficiently trace the high frequency component of residual jitter even in the tangential servo system, the jitter cannot be eliminated completely. Then in a digital information demodulation system 14, the cut-off frequency of the LPF 32 of a PLL circuit generating the read clock is set lower than the maximum frequency of the band of the tangential servo loop to cut off the high frequency component of the residual jitter thereby eliminating the residual jitter component. More preferably, the cut-off frequency of the LPF 32 is set lower than the warp frequency of a disc (30-8Hz in LDD) so as to eliminate completely also the jitter due to the warp of the disc.

Abstract: PURPOSE:To make it possible for an engine to ignite at a spark advance corresponding to the air-fuel ratio within its combustion chamber in the state of transient operation by igniting the engine with the use of the spark advance angle in accordance with the engine operating conditions in its intake stroke or prior to that. CONSTITUTION:In the ignition arithmetic timing every 180 deg. CA, a control circuit 35 gives a basic spark advance THB based on the rotating speed of an engine by a crank angle sensor 25 and on the amount of intake air by an air flow meter 7, which is corrected using an engine temperature 33, the air-fuel ratio by O2 sensor 27, etc.; thus the final spark advance THF is obtained. This is stored as the newest spark advance THFn, and the old spark advance THF0, which was previously obtained and stored, is used for actual ignition as the spark advance THF. An igniter 19 is turned on/off at the igniter on/off time set by the timer to supply a high voltage to the ignition plug. In this way, the engine can be ignited at an ignition time fit for the ratio of air and fuel which is taken in approximately 180 deg. CA prior to explosion.
