Title: Dc-dc converter
Inventor: KIKUCHI YOSHIHIKO
IPC: H02M3/335
Filed: 1988-05-31
Abstract: PURPOSE:To suppress the abnormal rise of output by controlling the time for the ON state of an apparatus through a signal from an output-sensing error amplifier and by controlling the primary current of a transformer through a signal from said error amplifier to regulate said output. CONSTITUTION:A resonance type DC-DC converter is composed of an output- sensing error amplifier A, a primary current sensor CT1 for a transformer T1, a current-voltage converter circuit B, a comparator circuit C, a one-shot multivibrator D, and a driver circuit E for Tr1. After the lapse of a period of time corresponding to the resonance frequency of a resonance circuit, said Tr1 is turned ON and the primary current IX of a transformer T1 is sensed by a sensor CT1. Thus, when a signal by said converter circuit B becomes larger by a signal from said error amplifier A, a pulse triggering said one-shot multivibrator D is sent from the comparator circuit to the driver circuit E to keep the Tr1 in the OFF state. As a result, said primary current IX can be controlled accurately.

Abstract: PURPOSE: To realize not only an assured channel selection but the excellent noise and tuning properties, by performing the channel selection for the receiver by the PLL synthesizer system and then securing a reception mode after channel selection for the receiver the S-curve following AFC action.  
     CONSTITUTION: When the channel key 25 is turned on, the switch change-over signal P/S is applied to the switch 22 from the control circuit 21. And the circuit is connected to the side of the point P to form the PLL loop 14. Thus the local oscillation frequency fL of the local oscillation circuit 10 is applied to the loop 14 via the dividing circuit 15, and the digital output value supplied from the loop 14 is converted into the DC voltage through the D/A converter 11 to be applied to the circuit  10 and the RF amplifier 3. When the loop 14 is locked, the switch 22 receives an  application of the signal P/S from the circuit 21. Then the switch 22 is changed  over to S to be connected to the S-curve following AFC action loop 9. In this AFC  action, the output of the loop 9 based on the S-curve signal of the wave detecting  circuit 6 receives the DC conversion 11 to be applied to the circuit 10 as well as  amplifier 3. Thus the receiver is put under the tuning mode.

Filed: 1986-06-10
Abstract: PURPOSE:To prevent the effective capacity of a storage space from being reduced by moving a guide coupler in the pressing direction by a preset stroke then returning it to the original position and moving a pusher in the opposite direction to the guide coupler. CONSTITUTION:When a motor 12 is activated based on a storage command, a storage room side plate 3 starts to be moved downward, a pusher 16 starts to be moved upward, and a bill 10 starts to be pushed in the storage direction. At the final stroke, the storage room side plate 3 is located at the lowest position and the pusher 16 is located at the highest position, thus the distance between the pressing face 16a of the pusher 16 and the upper face of a transfer guide 4 becomes a sufficient value for both ends of the bill 10 to start to be returned toward the original position. Next, the storage room side plate 3 starts to be returned upward and the pusher 16 starts to be returned downward, both ends of the bill 10 are pressed from both upper and lower sides between already stored bills 10A and the upper face of the transfer guide 4, thus the bill 10 is completely integrated with the already stored bills 10A.

Filed: 1983-07-22
Abstract: PURPOSE:To obtain an accurate rotating frequency output by varying the number of one variation of periodic magnetic frequencies in poles of a drive multipolar magnet to 2n times. CONSTITUTION:A frequency generator is formed of a drive multipolar magnet 1' having an irregular portion and a generating coil 5' having generating strands 4'a, 4'b for detecting a periodic change of a magnetic flux.
