Title: Automatic volume controller
Inventor: TAKEI TOSHIYUKI
IPC: H04R3/00
Filed: 1990-02-09
Abstract: PURPOSE:To prevent the generation of positive feedback or reproduction of extraordinarily large sound volume by separating and extracting voltage corresponding to a noise, and controlling an output increasing/decreasing means by the separated and extracted voltage corresponding to the noise. CONSTITUTION:A first impedance element 8 with impedance Z1 and a second impedance element 10 with impedance Z2 are inserted between an amplifier 2 provided with a volume 4 for increasing or decreasing the output of a sound signal to be reproduced and a speaker 6. The speaker 6 is used as a microphone as well. A noise detection circuit 12 inputs the output voltage e0 of the amplifier 2 and the voltage e1 between the impedance elements 8 and 10, and outputs the output voltage proportional to the voltage e2e2=e1-(e0-e1).Z2/Z1 corresponding to the noise. The volume 4 is controlled according to the output voltage from the noise detection circuit 12. Accordingly, the voltage corresponding to the noise can be easily separated and extracted through simple configuration.

Title: Short-circuit protection circuit of monitor
Inventor: YOSHINO SUMIYOSHI
IPC: H04L25/08
Filed: 1982-02-26
Abstract: PURPOSE:To prevent a fault due to fire in a circuit at the inside of a receiver,  by operating a failure stop circuit and stopping the output of a signal transmission circuit, if a signal line between the receiver and a relay device is short- circuited. CONSTITUTION:If the signal line 4 between the receiver 1 and the relay device 2 is short-circuited, a large current flows to a resistor R1, the voltage drop is amplified at an operational amplifier OP1, and the output voltage is charged in a capacitor C. In this case, since the current flows continuously, the capacitor C has no time for discharge, a base voltage of a transistor TR is increased and the TR turns on. When the TR turns on, a photocoupler PC is operated and a fault TR PT is turned on, then one input terminal of an AND gate A1 goes to L level. Thus, since the output of the gate A1 goes to L level, a signal transmission circuit 5 stops the pulse code transmission to the relay device 2. Then, the fault due to fire in an internal circuit in the receiver is prevented.

Title: Zeolite/resin composite material
Inventor: KUSAKAISHI SUSUMU
IPC: C08L67/00
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To improve temperature dependency of storage elastic modulus since decomposition of resin is inhibited and zeolite restricts a molecule of polyester by a method wherein a coupling agent is adsorbed on zeolite, and polyester resin is filled with a specific amount of the zeolite. SOLUTION: For a coupling agent, a silane coupling agent is principally used. Polyester resin is filled by 0.5-6wt.% with zeolite on which a coupling agent is adsorbed. In that case, for under 0.5wt.%, an effect is less, and when the resin is filled with zeolite exceeding 6wt.% in contrast with this, a ratio wherein an inside of the resin is occupied by zeolite becomes more. A discontinuous layer between the resin and the zeolite is produced numerously, and consequently thermal resistance is lowered. Therefore, zeolite/polyester resin composite material obtained by filling with a suitable amount of zeolite is improved in thermal resistance, which becomes material of excellent thermal stability.

Then the operating hande 7 is applied in the direction of tightening to push a shaft part 15 toward the bracket B, so that a tension plate 19 of the disc wheel D adheres tightly to the contact surface 3 of the bracket 4 through a stopper 18. Thus the spare tire S can be contained.

Abstract: PURPOSE: To inhibit corrosion of an electrode by performing an electrolysis in such a way that an electrolyte used contains water in a specified ratio to hydrogen fluoride, at the time of purifying industrial hydrogen fluoride by electrolysis.  
     CONSTITUTION: In the case of using a hydrogen fluoride aq. solution for producing electronic parts, problems are caused by the compounds of some elements such as arsenic, phosphorus, silicon and boron, which are presence as impurities in hydrogen fluoride, and therefore, these impurities are removed by performing electrolysis of the hydrogen fluoride. At this time, when an electrolyte used contains ≤200 mg of water to kg of HF, a nickel or carbon electrode is highly corroded. In the present invention, in order to inhibit corrosion of the electrode from being caused, the electrolysis is performed in such a way that the electrolyte contains ≥200 mg H 2 O/kg HF, to remarkably inhibit the corrosion. In this method, water originally present in hydrogen fluoride and water added to hydrogen fluoride are converted into oxygen, oxygen difluoride and hydrogen during the electrolysis, based on reaction represented by the formulas I and II. Also, the electrolysis is advantageously performed by adding water to the electrolyte in a 5 to 36 g ratio of water to 107.2 Ah of electric charge in the reaction represented by the formulas I and II.
