Title: Earthquake-proof automatic electric circuit breaker
Inventor: NAGAI MASAYA
IPC: H01H73/00
Filed: 1995-02-07
Abstract: PURPOSE: To sense an earthquake and automatically interrupt an electric circuit by providing a conical body top type vibration sensitive pendulum, a disc clamp, and a pressing element for pressing a cantilever spring contact terminal to a ratchet with beam so as to bring into contact with it. CONSTITUTION: A switch pressing element 16 provided on a ratchet with beam 10 presses a cantilever spring contact terminal 17 onto a fixed contact terminal 18 and brings it into contact with it, whereby an electric circuit is closed to make a current flow, and laid in usable state. When an earthquake takes place in this state, a conical body top type vibration sensitive pendulum 3 is fallen down, the disc clamp 5 of a shaft 4 acts on the lever 7 of a claw with beam to operate the lever 7, and the claw 6 of the claw with beam is released from the tooth 11 of a ratchet 10. Thus, the ratchet 10 is reversely rotated by the elasticity of a power spring 13, and touched and stopped by a reverse rotation ratchet stopper 14.  The pressing element 16 is moved upward by this rotation, the terminal 17 is returned and separated from the terminal 18 to open the electric circuit, and the current is interrupted. Since the electric circuit is thus automatically interrupted at the earthquake, occurrence of an electric fire can be prevented.

This slag is stripped by means of quarts glass, etc., and borax is added and the resulting mixture is heated at a temp. of the melting point (878 deg.C) of borax or above and agitated so as to take the noble metals into borax and form the lumps of mixture. Moreover, the above borax is in the form of decahydrated slat with a chemical composition of Na2B4O7 and is used by the quantity above 5-30 times the quantity (by weight) of the noble metals. Subsequently, the lumps of the mixture of the noble metals and borax are broken, so that noble metals can be easily recovered.

Title: Resistor and its trimming method
Inventor: MAKI HIDEYA
IPC: H01C7/00
Filed: 1994-02-28
Abstract: PURPOSE:To obtain a resistor which is small in allowable error in a relatively short trimming time by continuously trimming a blank resistor until a desired resistance value is obtained by reducing the revolving speed of the blank resistor after the resistance value of the blank resistor approaches the desired value and terminating the trimming when the resistance value substantially becomes the desired value. CONSTITUTION:At the time of trimming a cylindrical blank resistor 1, a spiral trimming groove 24 is formed with a cutting edge by moving the resistor 1 forward in the axial direction as shown by the arrow 23 while the resistor 1 is rotated in the direction shown by the arrow 22. When the groove 24 is formed by rotating the resistor 1, the groove 24 is formed at regular pitches W1 within the extend of one or more rotations from a point P0 to another position P1. The rotating speed of the resistor 1 is reduced when it is confirmed that the resistance value of the resistor 1 approaches a desired value with a resistance value measuring instrument. Therefore, the pattern of the groove 24 varies as that in the P1-P2 section and the pitch becomes W2 which is wider than the W1. The trimming is terminated when the resistance value of the resistor 1 substantially becomes the desired value.

Abstract: PROBLEM TO BE SOLVED: To provide an oxide sensor for measuring the quantity of oxides in a gas to be measured with extremely high accuracy without being affected by the moisture or carbon dioxide contained in the gas to be measured. SOLUTION: O2 contained in a gas G to be measured, introduced into a first chamber 60 through a first diffusion control section 56, is removed by applying a pump voltage Vp1 between pump electrodes 64, 66.

Abstract: PURPOSE: To improve the combustion efficiency by finely glanurating fuel under a centrifugal force with the rotation of a cylindrical diaphragm provided in a rotary cylinder successively provided at the tip of a rotary pipe connected to a fuel feeding pipe.  
     CONSTITUTION: When fuel such as low-grade oil is fed into a rotary pipe 2 through a fuel feeding pipe 1, it is transferred to a fuel heating section 8 with the action of a centrifugal force by the rotation of the pipe 2 and a line or groove (a). The rotation of a cylindrical diaphragm 5 integral contructed with the rotary cylinder 3 forces the fuel to be attached to the inner wall surface of the cylindrical diaphragm 5 under a centrifugal force. Moreover, the fuel is sucked fast as finely glanurated with the sucking action of an inner blade 7 through a hot air passage port 6. Consequently, the heated fuel is sent into a furnace body A in the form of particles and then, burned there after mixed with a secondary air delivered with a blade 4 for sucking the air and a tartiary air from outside the furnace.

Title: Dry etching device
Inventor: WANI ETSUO
IPC: C23F4/00
Filed: 1984-03-23
Abstract: PURPOSE:To uniformize the etching rate in a wafer, by exposing polyolefin resin near a substrate to be treated within a reaction container of a dry-etching device. CONSTITUTION:A cover 105 of polyethylene resin (polyolefin resin) is provided on the periphery of a wafer 104 supported by an electrode 102 and covered with an Al film. When a mixture gas principally consisting of BCl3 and Cl2 is injected from holes 108, it is also consumed and absorbed by the cover 105 and therefore the density of the etchant can be reduced in the periphery of the wafer. Accordingly, the density gradient between the peripheral and central portions of the wafer is reduced and the etching rate is uniformized within the wafer. Special consideration is required in arrangement of the cover 105: it will be advantageous if the cover 105 is arranged such that each wafer is stopped directly under one gas outlet 108 and then another so as to uniformize the etching rate also among the wafers. This constitution can prevent the reduction of a pattern and damages of the ground due to excessive etching in the periphery of the wafer.

IPC: G01R27/02
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To eliminate a dispersion in the measurement value obtained by the charging and discharging action of a capacitor when measuring the resistance value of each of resistance recording elements by providing a switching element which switches the capacitor to an action state or a non-action state, in series to the capacitor installed between a power supply line and a grounding line. SOLUTION: A switching element 103 is provided in series to a capacitor 102 installed between power supply lines 30, 40 and a grounding line. This switching element 103 performs an ON/OFF action in response to a control signal. That is, during a routine recording operation, the switching element 103 is set to an ON state and the capacitor 102 is set to the action state. Further, when measuring the resistance value of each of resistance recording elements r1-6, the switching element 103 is turned OFF, while the capacitor 102 is turned to a non-action state. In addition, at the time of measuring the resistance value of each of the resistance recording elements (r), the resistance recording elements (r) are sequentially turned ON one by one. Consequently, an electric current runs into only one of the elements (r) to be measured directly from a power supply V.  Thus it is possible to correctly measure the resistance value of each of the resistance recording elements.
