Title: Sound skip preventing device for cd player
Inventor: AKATANI SHIGERU
IPC: G11B17/028
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To maintain a constant distance between a recording surface of a disk and a pickup to prevent a sound skip even when external vibrations in a vertical direction are applied by causing stopper means to effect an elastic force in a downward direction with respect to a clamper only when a supporting member of a motor moves upward from a neutral position of a buffer member. SOLUTION: An external impact or vertical vibrations applied to a chassis 1 is absorbed by a buffer member 11. However, a part thereof is applied to a supporting member 12. Considering a motor configuration, a rotation shaft 14 is slightly movable in an axis direction due to an impact or a vibration. When a displacement of the rotation shaft 14 causes a clamper 6 to move upward with respect to the chassis 1, a small projection 21 pushes against stopper means of a plate spring 20 resulting in a reactive force therefrom. This prevents the rotation shaft 14 from being moved along the axis direction with respect to the motor 13. A constant distance between a recording surface of a disk 7 and a pickup 16 is maintained, whereby a focus control is stably maintained.

Title: Parallel processing type frame synchronizing system
Inventor: OGOSHI OSAMU
IPC: H03M9/00
Filed: 1990-07-09
Abstract: PURPOSE:To omit the frame synchronizing circuits and the parallel signal rearraying circuits in number accordant with the array state of parallel signals and to extremely reduce the circuit scale by applying the feedback control to the S/P conversion timing based on the result of frame synchronization. CONSTITUTION:The parallel signals 2 are inputted to a frame synchronization detecting circuit 13, and an intra-device frame counter 14 outputs an intra-device frame pulse 4. The reception signal inputted to the circuit 13 is compared with the pulse 4 on a time base. Then the coincidence/discordance of timing is detected and an S/P conversion control signal 5 is outputted. When no coincidence of timing is detected, the feedback control is applied to an S/P conversion timing generating circuit 12 with the signal 5. Then an S/P conversion timing signal 3 has a bit shift. Thus the array of the signals 2 is outputted with shift of one bit with the signal 3 that had a l-bit shift. As a result, both the frame synchronizing circuits end the parallel signal rearraying circuits can be omitted in number accordant with the array state of signals 2. Thus the circuit scale is reduced.

Title: Inspecting method of dc source voltage detecting circuit of ic tester
Inventor: KASADA YUKIHIDE
IPC: G01R31/28
Filed: 1984-08-30
Abstract: PURPOSE:To confirm the operation of a voltage detecting circuit and eliminate changer to an operator without causing power source deterioration originating from inspection by connecting an inspection sensor resistance in series with the resistance of a source voltage detecting circuit and short-circuiting and opening this resistance. CONSTITUTION:Inspection sensor resistances 300a-300n are connected to respective DC power sources 100a-100n in series with resistances 200-200n which determine currents to photocouplers 201a-201n. The resistances 300a-300n are shortcircuited normally through switches Sa-Sn. Then, when the resistances 301a-301n have prescribed value, operations of voltage stabilizing circuits 20a- 20n are inspected individually as to respective power sources. For example, when the switch Sa is turned off for the power source 100a, the input current of the photocoupler 201a decreases and its output also decreases. Then, a driver 202a begins to operate and an LED203a turns on. Consequently, it is confirmed that a detecting circuit 20a operates correctly.

IPC: F02P7/02
Filed: 1989-07-13
Abstract: PURPOSE:To provide a rotor head with which the injection pressure is hard to act on a resistance element, by connecting the two poles of the resistance element with No.1 part and No.2 part within an insulative case, and arranging insulative resin around terminals and said insulative case by means of injection molding. CONSTITUTION:A terminal 8 is divided into No.1 divisions 12 and No.2 division 13, which are coupled together through a box-shaped insulative case 14, whose top opens. A resistance element 15 is accommodated in the case 14, and the poles at the two ends communicate to flanges 12a, 13a, and the surroundings of this resistance element 15 in the case 14 are filled with potting agent 16. In this constitution, the voltage impressed from a point 7 is discharged to a side electrode 9 upon passing through No.1 part 12, resistance element 15, and No.2 part 13, and noise generated at this time is reduced by the resistance element 15. Because the resistance element 15 is accommodated in the case 14 in advance, the case 14 serves as protection member for the resistance element 15 against the injection pressure, which will not act directly on the resistance element 15 to reduce the likelihood of its breakage. Thus the yield from manufacturing will be enhanced.

Filed: 1981-11-13
Abstract: PURPOSE:To prevent an abrupt ATC braking from operating by superposing weak brake information on an ATC speed signal when the ATC speed signal of an adjacent forward block zone is the limit signal of lower level speed than the ATC speed signal in the zone where a train travels. CONSTITUTION:A logic unit C outputs a weak deceleration signal fb when the speed signal of a block zone nT is the lower level speed signal of the speed signal of a block zone (n-1)T. A modulator E modulates the signal fb outputted from the logic unit C with an ATC speed signal fei outputted from an oscillation and amplification selector D and is outputted from a transmitter F to a signal transmission line. A train unit carried on a train T produces a weak brake command (a) to a brake control unit when the signal fb is contained in the signal received by a train antenna unit TA. In this manner, it can prevent an abrupt ATC braking from operating, thereby improving the riding feeling.
