Title: Switching power amplifier circuit
Inventor: MITSUNAMI MICHITOSHI
IPC: H03F3/30
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To unnecessitate to differentiate edges of a drive signal, to drastically reduce loss and to perform efficient amplification by inserting an inductive element between an outputting stage and ground and utilize counter- electromotive force that occurs when one transistor is turned off to make inter- terminal voltage of the transistor 0 V when the other transistor performs the on-operation. SOLUTION: A condenser 10 and an inductor 11 are connected between an outputting stage and ground in order to compensate loss for an inclined part. For instance, when a field-effect transistor 6 is turned on and a field-effect transistor 7 is turned off, current flow into the inductor 11 through the transistor 6 and the condenser 10. Here, when the transistor 6 is turned off, counter- electromotive force occurs in the inductor 11, voltage between its drain and source is made 0 V before the transistor 7 performs an on-operation and after that, the transistor 7 performs the on-operation. This makes it possible to perform a switching operation with both the transistors 6 and 7 at 0 V between their drains and sources.

Title: In-mold plating molding method
Inventor: FUJITA OSAMU
IPC: B29C45/14
Filed: 1993-08-31
Abstract: PURPOSE:To form a metallic plated layer on the inside of a cavity side of a bottom force member, by a method wherein simultaneously with allowing a plating solution to flow in a plating solution flow path to be formed between the inside of a cavity side and the surface of a plating electrode material an electric current is applied to the bottom force member and plating electrode material. CONSTITUTION:A plating electrode material 2 is provided on the inside 11 of a cavity side of a mold in close vicinity to the inside. A space between the inside of a cavity and the electrode material is in such a form as to form an air gap having the fixed size for an inflow and outflow of a plating solution. An insulation material 6 is provided on the surface of the electrode member 2 by corresponding to a resist layer 5. Then the plating solution is allowed to flow in a plating solution flow path 4 to be formed between the inside 11 of the cavity side and the surface of the plating electrode material. Simultaneously with the above an electric current is applied to a bottom force member 1 and the plating electrode material 2 and a metallic plated layer is formed on the inside 11 of the cavity side. Since the electric current is held at low electric current density, to begin with, a uniform plated layer can be formed. Then a plated layer can be grown by short time electrification at high electric current density.

Title: Tape traveling controller
Inventor: MARUYAMA KAZUHIKO
IPC: G11B15/43
Filed: 1989-08-22
Abstract: PURPOSE:To prevent a tape from being damaged by sending a tension control driving signal when the tension control driving signal is smaller than a speed control driving signal and the speed control driving signal when the relationship of both driving signals is in the contrary. CONSTITUTION:When a tape 3 is under an accelerating state, a detecting signal of an angle detector 6 becomes larger, in other words, tension of the tape 3 becomes larger. In response to this, a value of the tension control driving signal V1 becomes smaller, and when it is below a value of the speed control driving signal V2, the tension control driving signal is sent from a switching means 5 to a driving means 16. By this method, a reel motor 2 is driven by the means 16 to control the tension of the tape 3, so that the tension of the tape 3 should never exceed allowable tension. Moreover, when the value of the signal V1 becomes larger than the value of the signal V2, the speed control driving signal is sent again to the means 16, and the motor 2 is acceleratedly driven by the means 16 to make the tape 3 travel at high speed. By this method, the tape can be accelerated without receiving any damage.

Inventor: SUDA KOICHI
IPC: G01D5/245
Filed: 1989-08-23
Abstract: PURPOSE:To suppress an eddy-current loss and to ensure a good output characteristic by forming a core with a bar-shaped laminated body of silicon steel plate, the tip end of which is formed to the tapered state with small diameter. CONSTITUTION:An electromagnetic pickup 2 is arranged to face oppositely to a signal rotor 1 which is formed with teeth on the peripheral surface and revolved synchronously to an internal combustion engine (not indicated in the figure). The pickup 2 is furnished with the core 3, permanent magnet 5 connected to the base end of core, and bobbin 9 on which a coil 7 is wound around the core housing part. The core 3 is the bar-shaped body laminated with plural silicon steel plates in approximately a table shape and formed in the tapered state as a whole. A specified magnetic flux distribution is formed in the core 3 by the permanent magnet 5 and a cross sectional area of its tip end is made small, therefore a leaking of magnetic flux from the tip end is suppressed to have the most suitable magnetic flux density. When the rotor 1 is made to revolve, the magnetic flux density is changed for every time the teeth formed on the periphery are faced oppositely to the tip end of the core 3, and the amount of magnetic flux intercrossed with the coil 7 is changed, then an AC voltage according to the revolution of rotor 1 is induced in the coil 7 and outputted as a signal indicating the number of revolution.

Title: Press forming method with excellent dimensional accuracy of formed part
Inventor: FURUNO YOSHIKUNI
IPC: B21D22/20
Filed: 1985-09-30
Abstract: PURPOSE:To produce the press formed part excellent in the dimensional accuracy by forming either a punch metal die or die metal die or the both with heating at the specified temp. in the forming of a thin steel plate. CONSTITUTION:A spring back is reduced in case of forming a high strength thin steel plate by increasing the temp. of either a punch metal die or die metal die or the both in pressing. In order to obtain this effect the punch metal die and die metal die are heated 100 deg.-400 deg.. By this heating the steel plate to be formed is softened and the conformability with the metal die is increased as well. On the other hand 400 deg.C is taken as the upper limit because of an extremely thin oxidized film being formed and the external appearance being remarkably spoiled on the steel plate heated upto high temp. while under cooling in the atmosphere as well as hardening the steel plate to be formed with heating of the metal die to high temp. too much. This method is effective for applying to a mild steel plate as well besides high strength thin steel plate.

IPC: H01L21/205
Filed: 1983-11-17
Abstract: PURPOSE:To increase the utilizing efficiency of a reactive gas by projecting the reactive gas from a nozzle to the point where the optical axis of a laser beam projected on a movable substrate crosses with the substrate and by projecting the laser beam only when the optical axis comes in accordance with the necessary position on the substrate surface as moving the substrate so as to form a selective film on the substrate. CONSTITUTION:Reactive gas are blown off from gas blow-off outlets 6a and 6b into a vacuum container. The front end of this gas outlet is thin and the gas is blown off from that end. Meanwhile, an optical axis of laser goes along the arrow A and is reflected by a mirror 3 and goes along the arrow B to reach the surface of a substrate 8. As a manipulator 9 can move upward, down ward, right and left, it is moved only at a constant pace and is stopped and the laser beam is projected the position where the manipulater is stopped. As the reactive gas is blown off in the vicinity of the substrate which is irradiated with the laser beam, a thin film of a-Si is formed on the substrate which is exposed to the spot of laser by laser CVD. Accordingly, if movement and stop of the manipulator is synchronized with the intervals of irradiation of laser, it is possible to form the spots of a-Si film on the substrate at a constant pace.
