Title: Transfer member for forming wiring, production method thereof and wiring board
Inventor: KURAMOCHI SATORU
IPC: H01L23/48
Filed: 1999-10-19
Abstract: PROBLEM TO BE SOLVED: To deal with fine patterning, sophistication and mass production of wiring board by providing a thin conductive layer separably. SOLUTION: At first, a thin conductive layer 120 is formed on one side of a base substrate 11 comprising a stainless conductive substrate exhibiting separability. When the thin conductive layer 120 is a copper plating layer, electrolytic plating is performed under specified conditions using a well-known copper plating bath. An adhesive layer 140 is then patterned on the thin conductive layer 120 according to the shape of wiring. The adhesive layer 140 is formed by dispenser method, screen printing method or intaglio printing method. Subsequently, the thin conductive layer 120 is etched using the adhesive layer 140 as an anti-etching mask to form a transfer member for forming the wiring. The adhesive layer 140 must function as adhesive at the time of transfer and as a mask at the time of etching the thin conductive layer 120.

IPC: H05K7/00
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To prevent hang-down of a cable bearer by a method wherein the intermediate part of the cable bearer is supported at the support axle having an outside diameter lower than that of a support roller rolling along the running passage of a machine bed and being coaxial with the support roller. SOLUTION: A cable bearer 1 has one end 3 fixed at a machine bed running along a rail 2 and the other end 4 fixed at the rail 2. An auxiliary rail 5 is arranged on the rail 2 in parallel to the rail 2 and two pairs of support rollers 6 and 6 are rolled on the auxiliary roller 5. The support rollers 6 and 6 are intercoupled through a coupling lever 7 with a constant distance kept therebetween and support axles 8 are arranged at respective axes the support rollers. The support axle 8 has an outside diameter lower than that of the support roller 6 and is coaxial with the support roller 6 and supports the intermediate part of the cable bearer 1. This constitution, since the intermediate part of the cable bearer is supported without being bent, reduces the occurrence of the damage of the cable bearer and a cable itselt.

The upper press 12 moves to the left in the direction of X-axis and the holder 11a, together with the label L and the cloth 7, moves to the left. When the needle insertion is started and sewing reaches the right end of the label L, the upper press 12 moves upward in the direction of Y-axis, and the needle 3 makes a sewing line at the right end of the label L. The upper press 12 and the holder 11a move to the right in the direction of X-axis so that the lower margin of the label L is sewn. When the sewing reaches the point F, the holder 11a moves downward, the sewing line reaches the point A, the sewing line is overlapped and the sewing of the label L is finished.

Title: Gas laser oscillation device
Inventor: KAKIZAKI KOJI
IPC: H01S3/0977
Filed: 1989-11-17
Abstract: PURPOSE:To obtain a gas laser oscillation device of X-ray pre-ionization type in which X-ray is made small in attenuation and laser oscillation of high repetition operation can be obtained by a method wherein an electron beam generating means which irradiates a target with an electron beam is provided, and the target is provided at an angle which is so set as enable an X-ray generated from the target irradiated with an electron beam to be reflected toward a transmitting window. CONSTITUTION:An electron beam 40 is made to travel intersecting equipotential surfaces 41 nearly at a right angle through a focusing electrode 35 and impacts against an X-ray generating anode 28. The impact angle is determined on an set angle formed by the focusing electrode 35 with the X-ray generating anode 28 provided to a recess 27. An X-ray generated by the impact of the electron beam 40 enables a primary discharge space to be pre-ionized penetrating through the top of an electrode section 26, a negative high voltage is applied to a cathode 22 from a high voltage power supply 24 after pre-ionization takes place, and then a primary discharge arcs to start laser oscillation. The X-ray 34 is introduced into the main discharge space 23 just after it penetrates only through the top of the electrode section 26, so that its traveling distance to the primary discharge space 23 can be sharply shortened. By this setup, an X-ray is hardly attenuated in dose, so that a device that laser oscillation of high repetition operation is realized can be obtained.

Title: Clock noise detection circuit
Inventor: SHIMOMUKAI KOICHI
IPC: H03K5/00
Filed: 1988-11-24
Abstract: PURPOSE:To detect noise without using a clock other than an input clock by generating a signal having a period twice that of an input clock, retarding the signal, using it as a permission signal for a counter and counting a change point of the input clock. CONSTITUTION:While the clock signal (a) is normal, number of changes in the trailing of the signal (a) when a retarded double period signal (c) is active is one, a count output of a counter 3 is '1' and a level of a signal (f) from the counter 3 is unchanged. Then if noise takes place in the signal (a), although a double period signal (b) of a FF 1 is simultaneously disturbed, the signal (c) keeps a double period. Then the change in the trailing of the signal (a) while the signal (c) is active is two or over, the count of the counter 3 is two or over and the signal (f) is changed. The change point is held by a FF 5 via an OR circuit 8 and a fault signal (h) is outputted at an output terminal OR. Since the signal (c) is used for the permission signal in the counter 3 and only a half the period of the clock signal is monitored, the permission signal and a reset signal are inputted while being inverted respectively and the counter A monitors the other period.

Title: Controller for inverter
Inventor: SHIMIZU HIROKI
IPC: H02P27/06
Filed: 1987-11-27
Abstract: PURPOSE:To utilize the energy of a flywheel sufficiently without lowering power efficiency, and to smooth torque pulsation by imparting speed-torque characteristics by controlling the output characteristics of an inverter. CONSTITUTION:Since a current command signal I has current-drooping characteristics and upper-limit limiting characteristics to the speed of an induction motor 3, the input/output characteristics of a current-drooping characteristics imparting circuit 9 are adjusted, thus making the induction motor 3 correspond to speed-torque characteristics. The current drooping characteristics are changed arbitrarily, thus operating the induction motor 3 by optimum speed- torque characteristics from the viewpoint of the economical efficiency of a system. The maximum torque of the induction motor 3 is limited by the working of an upper-limit limiter command circuit 12, thus reducing the capacitance of an inverter 2 and the induction motor 3.
