Title: Pedal driving device
Inventor: ISHII JUN
IPC: G10F1/02
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To detect the speed of a pedal with high accuracy without delay of detection from a low speed to a high speed. SOLUTION: A speed calculating part 14a prepares a speed signal Vc based on a position signal Fs outputted from an up-down counter and a driving current I* outputted from a driver. The speed signal Vc is exact without delay of detection in a low-speed region while the error increases in a high-speed region. On the other hand, a speed signal V* is a speed signal calculated based on the pulse interval of a pulse string outputted in accordance with the displacement of a pedal and has the delay of detection in the low-speed region. A cross- over network 14b mixes both speeds according to a cross-over characteristic so as to mainly use the speed signal Vc in the low-speed region and mainly use the speed signal V* in the high speed region and outputs a speed signal V*.

Title: Battery backup power supply circuit
Inventor: INABA KATSUHIKO
IPC: H02J9/06
Filed: 1991-08-27
Abstract: PURPOSE:To lessen the power loss of a charge circuit and facilitate the design of the charge circuit. CONSTITUTION:When DC power 1 is input into a switching DC stabilizing power circuit 10, the output from the primary winding of the transformer 11 of this switching DC power stabilizing power circuit 10 is input into the secondary winding of a transformer 30. And time output of the secondary winding is smoothed with a smoothing circuit 40, and a battery 20 is charged with this smoothed output through the charge circuit 40. Accordingly since the output of the smoothing circuit 40 is kept constant even if the DC input 1 fluctuates, the difference between the voltage applied to a charge circuit 50 and that of the battery 20 never fluctuates greatly.

Title: Radio data reception system for mobile slave station
Inventor: SANO TOMOMI
IPC: G01N33/543
Filed: 1986-10-08
Abstract: PURPOSE:To reduce the average current consumption of a battery of a mobile slave station and to increase the reception speed by setting the Q value of a resonance circuit to a high value in a normal state where the slave station waits for a call signal from a master station and switching the Q value to a low value to operate an amplifier of high gain when the call signal is detected. CONSTITUTION:When a modulated transmission signal 8a is received by a reception antenna LC resonance circuit 1 in a slave station 20, a controller 6 gives a high gain amplifier switching signal 10 to a high-gain amplifier 5 and connects an attenuating resistance 2 in parallel to the elements L and C of the LC resonance circuit. Then, the Q value of the LC resonance circuit 1 is switched to a low value. The input impedance before the validating of the high-gain amplifier 5 is high, and consequently, the current consumption is small, and the current consumption of a receiving circuit in the slave station in the call signal waiting state is kept minute. The response speed to the reception signal change of the resonance circuit is increased by the reduction of the Q value of the LC resonance circuit 1.

Filed: 1990-09-12
Abstract: PURPOSE:To copy an address multiplex control signal by sending duty information of a reproduced address multiplex control signal to a transmission destination and controlling the duty ratio of the control signal through the use of the sent duty information. CONSTITUTION:When a video signal is not delayed, a reproduced video signal is inputted to an output circuit 404 via a switch 403 and sent to a 2nd VTR, and when the video signal is delayed, the switch 403 selects the video signal from a D/A converter 407 and the selected signal is fed to the output circuit 404. A synchronizing separator circuit 408 separates a synchronizing signal from the reproduced video signal and gives it to a timing generator 409, from which a clock is generated and in which various timing signals synchronously with the video signal are generated. The digitized video signal by an A/D converter 405 is stored once in a frame memory 406 and then read. The timing with the duty information is coincident with the video signal by delaying the video signal by one frame and an address is matched accurately.
