Title: Manufacture of substrate for optical memory device
Inventor: HIROKANE JUNJI
IPC: G11B11/105
Filed: 1990-06-15
Abstract: PURPOSE:To form two kinds of grooves with different width by one laser beam by performing developing processing before irradiating a photoresist with the laser beam, and after that, irradiating the photoresist with the laser beam of a varied intensity. CONSTITUTION:The developing processing is performed before the irradiation of the laser beam on the photoresist 2. When a first photosensitive part with narrow width in accordance with a pre-format pit 7 is formed, exposure is performed by performing such adjustment so as to locate a photoresist plane 2a at a position on the convergence point (f) of the laser beam converged through a convergence lens 4. Meanwhile, when a second photosensitive part with wide width in accordance with a guide groove 6, the exposure is performed by changing the position of the convergence lens 4 to an upper position, and locating the photoresist plane 2a at a position separated from the convergence point (f) by the convergence lens 4 by prescribed distance. Thereby, it is possible to form the two kinds of grooves with different width by one laser beam, and to simplify constitution, and to easily perform maintenance management.

Title: Phase-conversion transformer
Inventor: FUJISAKI MITSUHIKO
IPC: H01F30/14
Filed: 1979-12-10
Abstract: PURPOSE:To obtain the transformer of small size and light weight as well as to eliminate the noises caused by a reactor using a method wherein a V connection is employed for the primary winding and a specific connection is employed for the secondary winding, thereby enabling to obtain the balancing circuit requiring no balancing reactor. CONSTITUTION:The primary winding of the transformer is V connected for a U phase and a V phase only, and the secondary winding is connected in such a manner that its W phase ab has reversed polarity against the W phase of normal delta connection. Further, a single phase load is connected between the terminals u and v of the secondary winding and a capacitor is connected between terminal v and w. And the windings, the forms and the like are adjusted so that the current ir of the secondary winding of the W phase will become 1/3<1/2> time of the current iL running to the single phase load, thereby balancing the three phases locatd on the primary side. Also, as the current ir varies according to the mutual inductance between the W phase winding and other phases, the capacity of the inductive reactance is brought to the normal value by adjusting the number of windings of the W phase winding. As a result, a three-phase/single-phase converting device requiring no balancer reactance is obtained, the device is miniaturized and light- weighted, and the noise caused by the reactor can be eliminated.

Title: Pulse generating circuit
Inventor: SOEJIMA TETSUO
IPC: H03K5/04
Filed: 1979-12-12
Abstract: PURPOSE:To generate pulses of a random duty ratio by permitting a counter, having alternate initial values, to count from those initial values and by inputting a carry to a flip-flop every time its count value exceeds a maximum value. CONSTITUTION:Counter 21, when providing a four-bit count, can count up to maximum value M which is 15. To obtain a duty ratio of 5:3, a pulse signal is supplied to terminal T of flip-flop 23 at time intervals of 5:3. For this purpose, since a carry is generated every time counter 21 counts up over 15, the generation of the carry should be at time intervals of 5:3. Then, every time the output of flip-flop 23 is inverted in response to the initially set-up input of counter 21, 11 and  13 are alternately set in the counter, so that a signal of the 5:3 duty ratio can easily be obtained.

Title: Clock switching circuit
Inventor: ADACHI MICHIO
IPC: H03K5/00
Filed: 1986-07-08
Abstract: PURPOSE:To avoid malfunctions of a clock switching circuit by completing the switch of input clocks against output clocks without producing any noise. CONSTITUTION:A clock switching circuit is first reset with a reset signal RE SET of H together with a selection signal DATA set at L. Under such conditions, an input clock CLK1 is outputted to an output clock CLK0. Then the signal RESET is set at L at a time point t1 to release the reset state of the switching circuit. While the signal DATA is set at H at a time point t2. Thus the signal DATA is latched at the first rise edge of the clock CLK0 at a time point t3. Then an internal selection signal A is changed to H from L; and an inverted section signal, the inverse of A is changed to L from H. Then the output Q is obtained synchronously with an clock input, the inverse of CK since the input D1 of a gate switching circuit 2 is kept at '1'. Thus the clock CLK1 does not emerge any more at the output of an AND gate 4 and the clock CLK2 does not emerge any more at the output of an AND gate 5.

Title: Electrode feeding device for electric discharge machining
Inventor: MORITA HIROMITSU
IPC: B23H7/32
Filed: 1993-06-30
Abstract: PURPOSE:To provide an electrode feeding device for electric discharge machining which can feed only the electrode backward, allows continuous service of the electrode, presents good response in the machining operations, and which can be structured in a small size. CONSTITUTION:The first piezo element 11 and second piezo element 12 both being of laminate type and secured to the slope part 13a of a pedestal 13, and the other ends of the elements 11, 12 are coupled with an electrode driving part 14. An insulation 15 presses an electrode 17 to the electrode driving part 14 with the energizing force of a coil spring 16. A difference is generated in the elongation/contraction amounts of the two piezo elements 11, 12 by dislocating the phases of the drive voltages to be impressed on them. The generated difference causes the electrode driving part 14 to make a circular motion, and the electrode 17 solely is fed backward with the friction force generated relative to the part 14. This enables fine adjustment of electric discharge machining, and the device can be embodied small due to low voltage and lightness.
