IPC: C01B31/04
Filed: 1988-04-15
Abstract: PURPOSE:To obtain the graphite molding which has the desired shape to allow utilization over a wide range by the relatively easy process of a simple operation and is light in weight and porous by putting an expansive graphite raw material into a form consisting of an air permeable material and heat-treating the same in this form. CONSTITUTION:The expansive graphite raw material or the mixture composed of the expansive graphite raw material and expansive graphite is put into the form consisting of the air permeable material and is heat-treated in this form to change the expansive graphite raw material to the expansive graphite by which the expansive graphite molding having the desired shape is obtd. The resulted expensive graphite molding is impregnated with a resin and is heat- treated to cure the resin or after the molding is subjected to an infusibilization treatment, the molding is carbonized by heating at 800-3,000 deg.C in an inert gaseous atmosphere, by which the graphite/carbonaceous molding is produced. The expansive graphite raw material to be used is preferably the interlayer compd. formed by treating the particles of graphite such as natural flake graphite, kish graphite and pyrolysis graphite having developed crystallinity with mixed acids of sulfuric acid, nitric acid, etc.

Title: Detector of abnormal tape position of cassette tape player
Inventor: FUKAZAWA TOSHIHIKO
IPC: G11B15/02
Filed: 1985-04-26
Abstract: PURPOSE:To detect abnormal position of a tape and to inform it by connecting a conductive rubber provided at the outer circumference of the side face of a pinch roller and a capstan, applying a voltage to the connecting point and detecting the presence of a current of a circuit which is formed when the tape is loaded correctly between the both. CONSTITUTION:The conductive rubber 1 of the pinch roller and the capstan 6 are connected via a power supply 7 and an ammeter 8. When the tape 11 is at a normal position, that is, the tape exists between the capstan 6 and the conductive rubber 1, the circuit is closed and a current flows. When the tape 11 goes to the rear side fo the capstan 6, since the circuit is opened, no current flows to the circuit. Thus, the abnormal position of tape is detected electrically and a signal is sent to a tape deck eject or indicator display.

Title: Manufacture of voltage non-linear resistance body and arrester
Inventor: YAMADA SEIICHI
IPC: H01C17/00
Filed: 1991-04-23
Abstract: PURPOSE:To form a ZnO element having excellent electric power charging life and an arrester by conducting two cycles of heat treatment in which combination of temperature rise and fall rate after the sintering of ZnO element is moderated. CONSTITUTION:Raw materials including ZnO as the main element and metal oxides such as Bi2O3 are mixed. The mixed material is first sintered for one (1) to 12 hours at 1050 to 1300 deg.C. The temperature rise and fall rate in this process is set to 300 deg.C/h or less which does not bring about thermal breakdown of ZnO element. At the time of completing the sintering process, the temperature ms lowered up to 300 deg.C or less to stabilize crystallization of element and structure of grain boundary. After the temperature us lowered up to 300 deg.C, heat treatment is executed. In the first heat treatment, the sintered ZnO element ms heated up to 800 to 950 deg.C to execute the heat treatment for one (1) to three (3) hours Bi2O3 within the ZnO element is dissolved to generate type Bi2O3 in the ZnO element when the temperature is lowered. Thereby, operation life characteristic of element can be improved. An arrester is formed by inserting a voltage non-linear resistance body 1 forming an electrode to the end face except for the external circumferencial surface of a cylindrical sintered body into an insulator tube 2.

Title: Parts aligning feeder
Inventor: TAKANAKA HIDEYUKI
IPC: B65G27/02
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To make even an electrolytic condenser being different in a head size and a gravitational center position so as to be aligningly fed in combination by flexuously forming a suspending part so as to make either of a short part or long one of a lead part face to the front in proportion as magnetic attraction becoming lessened. SOLUTION: A lower end face of an upstream end 53s of a guide plate 53 is formed into a streamline shape and, after a long lead contacts with this upstream end 53s in a first gap G1, it is guided to a lower end face of the streamline shape, turning it round to the lower side, and then it is transferred along the lower end face of the guide plate 53. A short lead is attracted by a second magnet 59 and it is turned upside, while an electrolytic condenser is transferred after being arranged in the vertical direction. The long lead is transferred to a second gap G2 along the lower end face of the guide plate 53, while the short lead is attracted upward and being rather delayed as its attraction is lowered at a downstream end 59e of the second magnet 59, arriving at a transition region Gt, its attraction is extinguished and thus it gets into the second gap G2.  With this constitution, this electrolytic condenser being large in the head size and high in the gravitational position is aligningly conveyable without hindrance.

That is lowering of an external light-emitting efficiency is little. Further, since the GaAs layer 5 does not contain Al, the AuGeNi electrode 4 performs good ohmic contact to the GaAs layer 5. Further, AlGaAs layers 1, 2 are formed by a liquid growth method and the GaAs layer 5 is formed by an MOCVD method.

Title: Constant temperature type heat flow flux sensor
Inventor: MIZUSHIMA KIYOSHI
IPC: G01K7/18
Filed: 1989-04-11
Abstract: PURPOSE:To reduce the cost of the sensor and to make stable measurement with high accuracy by baking a resistor having a large coefft. of temp. resistance on a ceramics substrate having a low thermal conductivity. CONSTITUTION:The sensor is constituted by baking the resistor 2 consisting of the material having the large coefft. of temp. resistance onto the substrate consisting of the ceramics having the low thermal conductivity, connecting lead wires 3, 3' to both sides of the resistor 2 and coating the outside surface of the resistor 2 with a protective film 4. Since the heat conduction from a heat transmission tube mounted with the sensor cannot be disregarded with the substrate 1, the material having the lowest possible thermal conductivity is selected and the better result is obtd. with the smallest possible thickness of the substrate 1. For example, zirconia ceramics having the high strength to allow the working to a small thickness and having the low thermal conductivity is effectively usable. The material having the large coefft. of temp. resistance is preferable for the resistor 2 and a heating element part baked with, for example, nickel or the like on the substrate is formed. An inorg. thin film consisting of glass on the like is used for the protective film 4. The stable measurement is made in this way with the high accuracy.
