IPC: G11B27/024
Filed: 1993-08-06
Abstract: PURPOSE:To surely make possible insertion editing in a video tape recorder in which a tracking control is performed based on a pilot signal recorded together with a video signal. CONSTITUTION:Offset voltages V1, V2 are superimposed on a tracking error signal TE generated by using tracking heads 13A, 13B preceding thereto. At the time of reproducing signals, the signal level of the tracking error signal TE is compensated by the amount of mounting errors of reproducing heads 12A, 12B with respect to tracking heads 13A, 13B. Further, at the time of the insertion editing, the signal level of the tracking error signal TE is also compensated by the amount of mounting errors of recording heads with respect to tracking heads 13A, 13B.

Title: Stamping device
Inventor: YAMAMOTO YOSHIHIRO
IPC: B41K3/64
Filed: 1981-12-26
Abstract: PURPOSE:To prevent stamping positions from dispersing and concurrently to reduce occurrence of noises by a method wherein a tail end and a head stamping part are arranged sequentially in the feeding direction of matters to be stamped. CONSTITUTION:Tail end stamping positions 7and head stamping positions 5 are arranged sequentially in the feeding direction of matters to be stamped like postal matters. When postal matters P1, P2 are fed under the conditions of (a)-(d), the tail end stamped hub 7 and the head stamped hub 5 operate respectively as shown in (a)-(d) and the tail end stamped hub 7 and the head stamped hub 5 do not operate concurrently. Thus, stamped positions make no dispersion and occurrence of noises can be reduced. Additionally, the lack of concurrent motion can unify the driving DC power circuit for the tail end stamped hub 7 and that for the head stamped hub 5 and makes possible simplified structure and reduced cost.

Title: Ultrahigh-speed synchronizing pulse source
Inventor: KATAGIRI YOSHIMASA
IPC: H01S5/042
Filed: 1996-08-16
Abstract: PROBLEM TO BE SOLVED: To synchronize an optical pulse, having repetitive frequency higher than a specified GHz with an electric signal by generating a beat signal between modulation sidebands of synchronous mode or between the modulation sideband and an adjacent synchronous mode from a photodiode and constituting a phase lock loop using the beat signal. SOLUTION: An intensity modulator 14 is driven at a modulation frequency of 20GHz to generate a primary modulation sideband, at an interval of 16GHz, which is converted through a photodiode 15 into an electric signal. A beat signal (16GHz) between the primary modulation sideband and an adjacent synchronous mode is used in a phase lock loop. A beat signal from the photodiode 15 is inputted through an amplifier 16 to a mixer 17, where the phase is compared with that of a sinusoidal wave signal of 16GHz, outputted from an electric oscillator 22. An error signal thus obtained is passed through a low-pass filter 18 and an amplifier 19, before being superposed on a reverse bias voltage to an oversaturated absorbing region 101. Consequently, an optical pulse train generated from a receiving mode synchronous semiconductor laser 10 is synchronized with the electric oscillator.

SOLUTION: This unit detects a front vehicle an inter-vehicle distance between the cars running front car speed, the ON and OFF operation of a cruising control unit 40, the ON and OFF operation of braking operation and brake pressure and inputs in the cruising control unit 40. Based on the these input signals, the cruising control unit 40 keeps a fixed speed mode that maintains car speed at a set value while the inter-vehicle distance is equal to or larger than the set value and keeps a follow-up speed mode that maintains car speed at a specified set value while the inter-vehicle distance is smaller than the set value for controlling the acceleration speed and deceleration speed of the car by means of a throttle actuator 25 and a brake actuator 26 based these modes.  In the case where the follow-up speed mode is held continuously for a specified time, the set car speed is changed to a higher speed than an average car speed. In the case where when brake operation is detected in the follow-up speed mode, brake pressure is equal to or lower than the value set and car speed is equal to or higher than the lower limit speed, the cruising control operation released by braking operation is restored when releasing braking.
