Title: Oscillation detection circuit
Inventor: OYAMA KAZUHISA
IPC: H03B1/00
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To allow the circuit to easily change an oscillation detection level and to reduce current consumption, even when the amplitude of an oscillation signal is small by using a current limit means, so as to limit a current flowing to a differential amplifier. SOLUTION: A reference voltage is given to the gate of a transistor(TR) 4 that is a first input terminal B of a differential amplifier 1 and an oscillation signal is given to the gate of a transistor(TR) 5 being a second input terminal X, a voltage of a capacitor 11 is changed in response to an output of the gate, and an oscillating state of the oscillation signal is detected based on the voltage. Thus, the oscillation detection level is easily changed by changing the reference voltage given to the first input terminal B. Since a current flowing into the differential amplifier 1 is limited by a transistor(TR) 7, even when the amplitude of the oscillation signal is small, the current consumption is reduced.

Abstract: PURPOSE:To produce a thin film having a large area and a small distribution of film thickness and film qualities in manufacturing an oxide superconducting thin film having a large area by laser abrasion method by increasing partial pressure of oxygen at the central part of a film forming face of substrate. CONSTITUTION:In forming an oxide superconducting thin film having a large area by laser abrasion method by irradiating a target 5 with laser beam and growing a thin film on a substrate 2 arranged opposingly to the target 5, oxygen is fed from a ring-shaped nozzle 6 having such a size as possible to put the film forming face of substrate in the inside of the nozzle, pressure at the central part of the film forming face of substrate is increased, partial pressure of oxygen at the peripheral part is reduced so that a thin film is grown in the same way even at part apart from the tip of a bloom (plasma which is collection of active film-forming particles) as at the central part. For example, partial pressure of oxygen at the film forming face of substrate has a distribution wherein partial pressure is 0.8Torr at the central part, 0.5Torr at part 10cm apart from the central part and 0.2Torr at part 20cm apart from the central pare, preferably.

Title: Thermal transfer printer
Inventor: KOMURO KIYOTO
IPC: B41J17/24
Filed: 1987-12-11
Abstract: PURPOSE:To enhance a color overlapping accuracy particularly in a three-color system wherein colors are arranged in order, by a method wherein, an ink film feed force is set larger than the total loads in carrying an ink film by approximately a fixed difference, and a film holding force between an ink film and a transfer paper is set larger than the difference. CONSTITUTION:A film tension after transfer FR, that before transfer FB, and a load FH of a recording head 4 acting to an ink film 1 are made to meet a formula 1 regardless of a loss of a roller shaft such as a platen. Where a rotation load torque of the platen is TP and a platen radius (r), a paper back tension (FP=TP/r) can be applied to a transfer paper 2, and FR is determined to meet a formula 2. With the rotation of a paper feed roller 5, both the ink film 1 and the transfer paper 2 are carried in a direction A. Furthermore, where an ink film holding force alpha by the transfer paper acting at the contact part between the ink film and the transfer paper is determined by a formula 3, a load applying on the paper feed roller 5 comes to FP-alpha. Since the value FP-alpha can be set small, a remarkably small paper feed force is made available.

Title: Electronic circuit component
Inventor: HOSOI YOSHIHIRO
IPC: H05K1/03
Filed: 1986-12-26
Abstract: PURPOSE:To remarkably improve the reliability of polyimide resin and metal thin film in an electronic circuit component made by forming the metal thin film on the polyimide resin formed on a substrate surface with respect to bonding strength by specifying the formula of the resin. CONSTITUTION:A polyimide resin layer is formed on a substrate surface which forms an electronic circuit component, and a metal thin film is formed on the layer. In this case, the resin selects a type represented by the general formula. In this formula, at least one of functional groups R1, R2, R3 is selected from an electron attracting group. The bonding energy of the resin and metal is remarkably high in the chemical bond of identicalC-O-M structure or identicalC-M structure formed by supplying the outer orbital electrons of the metal to the carbonyl group of the polyimide. Accordingly, the bond of the resin to the metal is not cut even in a high temperature oxygen atmosphere, thereby significantly improving the reliability with respect to the bonding strength.

SOLUTION: A side face electrode 4 connected electrically to the radiation electrode 2 and the earth electrode is divided into a plurality of side face electrodes 4a, 4b, and a feeding electrode 10 is placed between the side face electrodes 4a, 4b. Although the feeding electrode 10 is connected to the radiation electrode 2, because the electrode 10 has a gap 12a (12b) with respect to the side face electrode 4a (4b) formed on a side face 1c of a board 1, the feeding electrode 10 is not in contact with the side face electrodes 4a, 4b.  Since the side face electrodes 4a, 4b and the feeding electrode 10 are formed on the same side face 1c in this way, the shape design or the like of the side face electrodes 4a, 4b and the feeding electrode 10 on the side face 1c can be made at the same time, a degree of freedom of product design and a degree of freedom of mount position can be enhanced by making the size of the antenna small and the profile thin.
