Title: Braking device of magnetic recording and reproducing device
Inventor: HAGIWARA KAZUYOSHI
IPC: G11B15/18
Filed: 1994-04-14
Abstract: PURPOSE:To produce a slider absorbing mechanism in which during the transition from a braking released condition to a braking condition, a spring section formed on the tip section of the slider impacts to a stopper, the slider stops and the number of parts of the mechanism is reduced without using fixing means such as adhesive. CONSTITUTION:A main cam gear 7 rotates in a clockwise direction from a control released condition, a brake lever 8 rotates in a clockwise direction. When a trigger 12 and a slider 13 move to a left direction, the tip section of the trigger 12 engages to an impeller 4. When the impeller 4 rotates in the rotational direction of a driving motor 1, the trigger 12 is pressed in the direction indicated by an arrow 12b. At that time, the trigger 12 is engaged to a stopper 13d of a cam 13c of the slider 13 and therefore, the trigger 12 is kept in a non-rotating condition. Thus, the rotation of the impeller 4 is stopped by the trigger 12, a torsion spring 3 engaged to the impeller 4 is slightly opened and the impeller 4 is kept slipping on an output shaft of the motor 1. When a mode switch detects the location of the trigger 12 to be at a prescribed position, the motor 1 stops by the signal.

IPC: H01B7/00
Filed: 1995-03-31
Abstract: PURPOSE: To simply conduct the connecting/disconnecting work without removing a battery cable from a battery by providing an insertable and removable insulating plate between the terminal of one cable and the terminal of the other cable. CONSTITUTION: An insulating plate 21 is provided between the terminal 3 of one cable 1 and the terminal 7 of the other cable 2. When the plate 21 is removed, the contact faces 6, 10 of the terminals 3, 7 of both cables 1, 2 are elastically displaced in the longitudinal direction of both cables 1, 2 respectively. Since the terminals 3, 7 are pressed to each other, they can be kept in face contact in the pressed state, and a current used in the vehicle electrical system can be fed there. When the plate 21 is inserted or removed between the terminal 3 and terminal 7, the connection or disconnection of the cables 1, 2 can be selected without removing the cables 1, 2 from a battery, and the cutoff work of the battery cable can be simply conducted without using a tool. The maintenance property of the vehicle electric system can be improved.

Title: Digital amplitude modulator
Inventor: YURA HARUHIKO
IPC: H03F3/68
Filed: 1995-03-31
Abstract: PURPOSE: To decrease noises caused by switching from a variable amplitude output amplifier to a fixed amplitude output amplifier by composing the device of the constant amplitude output amplifier and the variable amplitude output amplifier and setting the amplitude of the variable amplitude output amplifier at the time of maximum output larger than the output amplitude of the constant amplitude output amplifier. CONSTITUTION: The maximum output of a variable amplitude output amplifier A0 is set at a value larger than the output of constant amplitude output amplifiers A1 to A5 for about 20%. When dropping a power supply voltage while the amplifiers A1 to A3 and A0 are operated by the input from a modulating signal source 12, the component of low-order bits from an A/D converter 13 is enlarged and the output of A0 is increased. When the output of A0 is increased to about 1.2-fold resultant output of A1 to A3, the amplifier is switched to the next amplifier A4. When reversely increasing the power supply voltage, the output of A0 is decreased so that output power can be fixed and when the output of A0 is turned to '0', the A3 is stopped. Thus, the frequency of switching is decreased and noises are reduced.

Title: Time delay device for light signal
Inventor: JOPSON ROBERT MEACHEM
IPC: H04J14/02
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain a desired optical channel having desired corresponding time delay by arranging a filter which selects a specific 'teeth' in an optical frequency comb on the output side of an optical comb generating device. SOLUTION: The optical frequency comb 122 has many channels which are separated in terms of time and frequency. The frequency interval between adjacent channels, i.e., 'teeth' of optical frequency combs 122 and 150 is determined by the frequency of a shifting signal applied to optical comb generating devices 126A and 126B. The time delay of the respective 'teeth' of the optical frequency combs 122 and 150 is equal to the frequency at which signals of the 'teeth' make rounds of an optical fiber loop of the optical comb generating devices 126A and 126B. Filters 140 and 142 which specify specific 'teeth' in the optical frequency combs 122 and 150 are arranged on the output sides of the optical comb generating devices 126A and 126B to obtain a desired optical channel having desired corresponding time delay.

Filed: 1995-03-31
Abstract: PURPOSE: To improve the efficiency of an inverter and to make it possible to control the current over a broad range by forming a series resonance circuit on the primary side of a step-up transformer, and turning on/off the series resonance circuit by a switching element at the timing where phase is advanced than the resonance frequency of the resonance circuit. CONSTITUTION: In a quasi-E-class voltage-resonance inverter, the flowing direction of a DC I31 , which is supplied from a DC power supply, is alternately reversed by the operation of an on/off switching element S31 , and the DC is converted into an AC I32 . At this time, the series resonance circuit, which is constituted of an inductor L32 and a capacitor C32 , is formed on the primary side of a step-up transformer. The seried resonance circuit is turned on/off by the switching element S31 at the timing where phase is advanced than the resonance frequency of this resonance circuit. Thus, the efficiency of the quasi-E- class voltage-resonance type inverter is improved, and the current control can be performed in the broad range.

Title: Forming device for thin film of developer
Inventor: NAKAMURA TOSHIHARU
IPC: G03G15/08
Filed: 1985-04-12
Abstract: PURPOSE:To increase the convergence of lines of magnetic force on a magnetic blade by interposing a material which has high magnetic resistance between the N and S magnetic poles of the fixed magnet in a sleeve and isolating the N and S magnetic poles from each other. CONSTITUTION:A control blade 6 made of a magnetic body is arranged in a scraper shape almost above a member which supplies a developer to a photosensitive body, e.g. sleeve 2. The magnet 7 is provided fixedly in the sleeve 2. Then, the part between its magnetic poles S1 and S2 is composed of the material having high magnetic resistance, e.g. Al and Cu or a gap. In this constitution, both magnetic poles N1 and S1 are isolated from each other, so there is no lines of magnetic force forming a closed loop in the magnet and lines of magnetic force are converged on the magnetic blade 6 having high magnetic permeability. Consequently, the relatively weak magnetic poles prevent magnetic particles from leaking out of a developer container.

Title: Signal output adjustment device
Inventor: KASAI JOJI
IPC: H03F1/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide the signal output adjustment device such as a muting circuit not causing a click noise unpleasant to ears produced in an operation switching state or the like. SOLUTION: A manual switch SW1 is open at signal reproduction. A control circuit 30 makes contacts of relays RL1, RL2 open so as to keep a variable impedance circuit Z1 to be a high impedance. Thus, a signal is outputted to an output terminal 22. Then the manual switch SW1 is switched to be closed. The control circuit 30 closes the contact of the relay RL2 and controls the variable impedance circuit Z1 to change the impedance from a high to a low impedance along with a proper time constant. Thus, a click noise caused attended with the switching of the manual switch SW1 is not produced. After the impedance reaches a sufficiently low impedance, the contact of the relay RL1 is closed. The output terminal 22 connects to ground and the signal output is completely stopped. Thus, a sound is not leaked at muting ON.
