Title: Wire electric discharge machining method
Inventor: TAKAHARA KUNIHIRO
IPC: B23H7/02
Filed: 1992-05-22
Abstract: PURPOSE:To suppress a drum-form vibration generated in a wire electrode. CONSTITUTION:A wire electrode W is inclined by advancing an upper guide 8 or a lower guide, a little in the process progressing direction of the wire electrode W, so as to form a specific angle between the wire electrode W and the end face 14a of a work 14, and a cutting is started while maintaining this inclined condition. When the cutting is carried out a specific distance S after the cutting is started, the inclined angle of the wire electrode W is converted gradually to the designated angle of an NC program, and the electric discharge machining is carried out further along a preset formation.

Title: Orientation flat aligner of semiconductor wafer
Inventor: HIRAMATSU SHINICHI
IPC: H01L21/68
Filed: 1988-06-23
Abstract: PURPOSE:To prevent the error of orientation flat alignment due to the deformation of a cassette and cope with various sizes and forms of cassettes by attaching a roller and two supporting bars to a lifter which is coupled to a vertical movement mechanism. CONSTITUTION:After placing a cassette 2 on a cassette stage 3 by causing a lifter 8 to be in a state it lowers, the alignment of the cassette 2 is fixed by a cassette pressor bars 4a and 4b. Then, the wafer 1 is pushed up by raising the lifter 8 and a motor rotates a roller 5. As the roller 5 rotates, the wafer 1 turns. When orientation flat faces down, the wafer 1 is supported by the supporting bars 6a and 6b, and then, separated from the roller 5. Accordingly the rotation of the wafer stops. This mechanism prevents the error of orientation flat alignment due to the deformation of the cassette and can cope with various sizes and forms of cassettes.

Title: Delay circuit
Inventor: SAITOU TAKASHI
IPC: H03K5/13
Filed: 1983-08-29
Abstract: PURPOSE:To improve the selectivity of a delay to the leading and trailing of a pulse signal waveform by impressing an NOT output of a differential amplifier circuit to a diode and a capacitor connected in series and connecting a resistor to the diode and the capacitor in parallel. CONSTITUTION:A pulse is inputted differentially to inputs 15, 16 of the differential amplifier 14 and its output 17 is impressed to an impedance comprising the series connection of the diode 18 and the capacitor 19. Further, the resistors 22, 23 are connected respectively in parallel with the diode 18 and the capacitor 19 in order to operate the diode and form an RC integration circuit in said termination impedance. When the level of the NOT output 17 of the differential amplifier in the circuit goes from Lo to Hi, the diode 18 is conductive, the capacitor 19 is charged in a short time so as to quicken the leading of the pulse signal waveform. When the level goes from Hi to Lo, a reverse bias is applied to the diode 18, which is made nonconductive thereby slowing down the trailing of the waveform. As a result, a waveform where the difference between the leading time and the trailing time is large is obtained so as to improve the selectivity of the delay.

Abstract: PURPOSE:To reproduce a music signal with fidelity by improving the linearity of the sound pressure of a loudspeaker to an input without specially adjusting the loudspeaker by detecting current flowing through the loudspeaker and by exercising control over the input signal every moment by the detection output. CONSTITUTION:Output DC operating voltage compensating circuit 10 for main amplifier 3, current detector 11 for loudspeaker 4, etc., are provided. Namely, current detector 11 connected in series to loudspeaker 4 detects loudspeaker current, which is inputted to control input terminal 9 of gain control circuit 8 via integral network 12 and DC amplifier 13; when the input to terminal 9 is great, the gain of circuit 8 is increased to improve the linearity of the sound pressure of loudspeaker 4 without specially adjusting the loudspeaker 4 even if the impedance fluctuates owing to the heating of the voice coil of loudspeaker 4. Said circuit 10 prevents the output DC operating voltage of main amplifier 3 from fluctuating owing to fluctuations of the music signal level and ambient temperature. Thus, the musci signal is reproduced with fidelity.
