Title: Video reproducing device
Inventor: OHASHI TOMONORI
IPC: H04N5/7826
Filed: 1989-05-16
Abstract: PURPOSE:To correct a time axis error with high accuracy by passing a reproduced FM signal through a variable delay line after it is demodulated into a base band video signal and controlling the delay time with a dither signal from a stable reference signal source. CONSTITUTION:An FM signal reproduced from a head 1 is amplified by a head amplifier 4, subject to amplitude limit with a limiter 5, demodulated into a base band video signal with a demodulator 15 and inputted to a variable delay line 6. A dither signal exciting a head 1 is converted into a signal cancelling the time axis error by the head excitation at an equalizer circuit 8 to control the output frequency of a voltage controlled oscillator 7 and the signal is fed as a clock of the variable delay line 6. Thus, the base band video signal passes through the variable delay line to correct the time axis error with high accuracy.

Filed: 1985-06-04
Abstract: PURPOSE:To make the titled device inexpensive and compact by vibrating a storage type linear photodetector in the subscanning direction and applying weight addition in the subscanning direction to extract a fogged picture signal thereby eliminating the need for a memory storing picture data by plural lines. CONSTITUTION:A CCD line sensor 11 is arranged while the picture arranging direction (lengthwise direction) is used as the main scanning direction on an image forming plane of an original picture 13 according to the preset magnification of an optical system 12. Then the sensor is vibrated reciprocatingly single in the subscanning direction on the image forming plane of the original picture 13 in response to the vibration signal from an vibration generator 14. The vibration mode of the CCD line sensor 11 and the periods (T1, T2...) of the stationary mode are set equally to the charge storage time. A picture signal for conventional one scanning line without fog is obtained in correspondence to lines l, l+1, l+2... during the periods T2, T4, T6.... On the other hand, the fogged picture signal in the subscanning direction is obtained by one scanning line while being subjected to weight-addition at each line in the subscanning direction during the periods T1, T3, T5... in the vibrating state.

Title: Character input device
Inventor: IMANAKA TAKASHI
IPC: G06F3/02
Filed: 1984-06-14
Abstract: PURPOSE:To improve greatly the fatigue and anxiety of an operator when he/she performs key inputs by vibrating a transparent piezoelectric element set at the position of a certain electrode of a transparent switch matrix when said electrode is closed. CONSTITUTION:When a transparent switch matrix on the screen of a plane display 28 is pushed, the electrode of a transparent electrode film 24 in a pushed section has contact with a transparent piezoelectric element 25 to close a circuit existing between the electrode of the film 24 and an electrode of a transparent electrode film 26 via a resistor 36 set on the side face of the element 25. When a pushed electrode on the film 24 is driven by the voltage modulated by a modulation part 35, the voltage is applied to the element 25 set between closed electrodes. Thus the distortions are produced and at the same time a current flows to the resistor 36. This current is earthed through a resistance 31. The coordinate position data is outputted by the voltage produced by the resistor 31. Furtheremore the voltage applied to the element 25 changes every time the pushed electrode on the film 24 is driven by a microcomputer 33. This produces also distortions and variations. When these variations are produced periodically by some ten times per second, an operator feels vibrations and confirms the key input.

At this time, a detection element 17 detects the magnitude of the exciting current so as to output an exciting-current signal. When the core 2 is excited, a detection coil 4 outputs an exciting-state corresponding signal. The exciting-current signal and the exciting-state corresponding signal are changed into direct currents by respective circuits 22, 23, the difference between them is computed by a differential amplifier 24, and a difference signal is displayed 28 via a display circuit 25, an A/D conversion circuit 26 and a CPU 27.

Title: Alternative selector
Inventor: BAN ITSUKI
IPC: F16F7/00
Filed: 1982-07-16
Abstract: PURPOSE:To eliminate impact sounds, by using just a single damper device to damp resetting motion of plural actuators. CONSTITUTION:When a cassette door 2 is set at the position shown by a solid line, a rack gear of an injection arm 29 does not engage with a pinion gear 28. Then the door 2 turns toward an arrow D when the engagement between a pin 2a and a release arm 32 is released. When the door 2 turns slightly, the gear 28 engages immediately the rack gear of the arm 29. Then a damper functions to turn slowly the door 2 toward the arrow D. When the door 2 is pushed by a finger in the direction opposite to the arrow D after replacement of the cassette, no function of the damper is applied. Therefore the door 2 turns in accordance with the pressing force.
