Title: Synchronous pulse generation device
Inventor: TAKESHITA HIROSHI
IPC: H04N5/93
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To output a precise synchronous pulse by shifting a gate signal by a period equivalent to a prescribed amount of phase shift if any in a reproduced video signal. SOLUTION: When a head changeover pulse is inputted to a counter 21a and a reproduction mode changes from a normal reproduction to a two-fold reproduction, a control signal is inputted so that a gate signal is delayed from a micro computer. The counter 21a adjusts a count value so that the gate signal is delayed only when the control signal and a head changeover pulse from a differentiation circuit 21b are inputted. When the reproduction mode changes from the normal reproduction to a still reproduction, a control signal is inputted so that the gate signal is advanced. The counter 21a adjusts the count value so that the gate signal is advanced only when the control signal and the head changeover pulse from the differentiation circuit 21b are inputted. Thus, the gate signal is shifted against the phase shift of a reproduced video signal.

Title: Power steering device
Inventor: MATSUOKA HIROSHI
IPC: B62D6/00
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To eliminate a delay in rising of an operating hydraulic pressure generated by expansion at a hose by a method wherein a rotation of an electrical motor is controlled in such a way that a flow rate of operating oil at an outlet port of an actuater is set to become a predetermined flow rate. SOLUTION: A calculator 1d subtracts a signal expressing a flow rate of operating oil returned back to an oil supplying tank 5a from a return flow rate sensing section 8 in reference to a voltage indicating signal applied to an electrical motor 4 corresponding to a target flow rate, and then gives a voltage indicating signal of difference to a motor driving circuit 2. The motor driving control circuit 2 controls a voltage applied to an electrical motor 4 in response to the applied voltage signal in such a way that an operating hydraulic pressure returned back to the oil supplying tank 5a may become a target flow rate. The electrical motor 4 rotationally drives the hydraulic pump 5. The hydraulic pump 5 discharges an operating flow rate of oil in response to a voltage applied to the electrical motor 4 so as to generate the operating hydraulic pressure.  With such an arrangement as above, it is possible to prevent an operating oil amount from being reduced by expansion of hose extending from the hydraulic pump 5 to a control valve 6.
