Title: Multicomponent mixed resin molding method and deivce thereof
Inventor: HORI TETSUHIRO
IPC: B29C45/14
Filed: 1991-07-02
Abstract: PURPOSE:To improve production efficiency by a method wherein the positions of nozzles are controlled so as to keep constant the pouring pressures of respective resin components in a mixing chamber in response to the changes of the flow rates, which change so as to maintain the resultant pressure of the mixing resin components in order to pour the mixing resin components, the controlling pressures of which are maintained just below the criticalpressure of a mold, in the mold. CONSTITUTION:A plurality of reactive resin components, the controlling pressures of which are maintained just below the critical pressure of a mold 60, are poured in a cavity 63. At the early stage of pouring, since the resistance in the cavity 63 is low and consequently resin pressure is low, the controlling pressures are maintained by increasing the deliveries of the resin components from a delivery port 64 by increasing the flow rates of pumps. At that time, the positions of nozzles 13 and 14 are controlled so as to keep the pouring pressures of resin components in a mixing chamber 15 constant also. When the resistance in the cavity 63 becomes larger and consequently the resin pressure becomes higher as the pouring proceeds, the deliveries of the resin components are gradually decreased so as to control the pressure in the cavity. Thus, the pressures of the respective resin components are maintained.

Title: Molding method for friction material
Inventor: YASUDA TAKESHI
IPC: B29B11/12
Filed: 1990-07-20
Abstract: PURPOSE:To eliminate the need for a heater and to heat the mixture of raw materials at the required low temp. and to perform pressure molding therefor by utilizing rubber and resin, etc., as a binder and imparting microvibration to the said mixture and causing self-heat therein. CONSTITUTION:The vibration conditions which are imparted to the mixture of raw materials for the friction material to be molded are set in a function generator 9. The mixture of raw materials is introduced into a bottom force 2. When a device is turned ON, a servo-amplifier 10 receives both a command signal sent from the function generator 9 and a signal sent from a differential transformer 6 and performs calculation, amplification and output. A servo-valve 11 is actuated by a command signal sent from the servo-amplifier 10. Liquid pressure supplied from a liquid pressure source 12 actuates a liquid pressure cylinder 8 through the servo-valve 11. This liquid pressure cylinder 8 lowers its rod. While a top force 1 imparts the preset microvibration to the mixture of raw materials in the bottom force 2, this mixture is repeatedly pressure-molded. Thereby the mixture causes self-heat release and gas generated in the inside is discharged and density of the whole molded form is uniformed. Since the mixture of raw materials is pushed into the bottom force 2 by the top force 1, extrusion of this mixture from the mold is made little. Flash is made small and the molded form having good quality is obtained.

Title: Voltage level converting circuit
Inventor: KONO JUNICHI
IPC: H03K19/018
Filed: 1984-09-12
Abstract: PURPOSE:To omit a resistance for bias voltage and to attain the reduction of cost with a voltage level converting circuit, by applying an intermediate level of the binary voltage supplied to the cathode side of a diode to an anode via a resistance and obtaining an output from the anode. CONSTITUTION:The cathode voltage of a diode 7 is set at a low or high level by turning on and off a switch 2. Here an intermediate voltage level +5V, for example, between low and high levels is applied to the anode of the diode 7 via a resistor 8. Thus a diode current flows to set the anode voltage at about 0V when a cathode is set at 0V. No diode current flows when the voltage +24V is applied to the cathodes. Then the anode voltage is set at +5V. Here the low/high levels of 0/24V are converted into the standard input voltage of a TTL logical circuit of 0/+5V, and applied to the TTL logical circuit connected to the anode. Then the high level of the converted output is changed by changing the level of the DC voltage applied to the anode of the diode. Therefore a diode can substitute a transistor and a resistance is omitted.

Abstract: PURPOSE:To provide an FPGA construction equipped with an antifuse element capable of accurately operating at a predetermined program voltage and its manufacture. CONSTITUTION:An opening 5 is formed in an insulation film 4 covering an aluminum wiring 2 in a lower layer; a Ti/TiN barrier metal layer 17 is formed over an exposed aluminum wiring 2, and this is used as the first electrode of the antifuse element. An antifuse film consisting of a silicon nitride film 20 (0.6<=N/Si<=1.2) is formed over it.

Abstract: PROBLEM TO BE SOLVED: To improve the pitting corrosion resistance and cracking resistance and to prolong the service life of the material by forming stainless steel or a coating layer on the surface by stainless steel in which the density of micro-defects as the specified surface opening diameter is extremely low, being equal to or below the specified one. SOLUTION: The density of micro-defects of 0.6 to <1000 nm surface opening diameter is <=60 pieces/μm2. As one method for prolonging the service life of the material, before the generation of big defects, the repair of the micro-defects of nanometer scale causing big defects is more effective. The repair of micro-defects is composed of each stage of mechanical polishing, cleaning treatment for the surfaces of defects, passivating treatment and the growth of oxidized coating films. In the final growth of oxidized coating films, after the passivating treatment, the surface is washed away by distilled water or ion exchange water, the water is blown off, and, after that, it is held in the air or in gas contg. >=20% oxygen. The granular or beltlike structure of the oxide formed by the passivation grows, and in this process, micro-defects are covered and repaired.
