Title: Surge absorber with safety function
Inventor: KARASAWA ATSUSHI
IPC: H01H37/76
Filed: 1990-06-18
Abstract: PURPOSE:To avoid ignition of a varistor element and a circuit to be protected by a method wherein a low melting point metal element is melted by heat from the varistor element and separated by the shrinkage of a heat-shrinkable insulating tube and the heat shrinkable insulating tube which is an insulator isolates the separated parts of the low melting point metal element from each other. CONSTITUTION:A surge absorber is composed of a varistor element which has an insulating coating made of inorganic material such as glass on its whole surface, a low melting point metal element and a plurality of heat-shrinkable insulating tubes which are provided with a predetermined interval. If a continuous overvoltage is applied, the varistor element 21 gradually generates heat and the heat is transmitted to the low melting point metal element 25 through the heat-conducting insulating coating 24 such as a glass coating to melt the element 25. At the same time, the heat-shrinkable insulating tubes 28 are made to shrink and separate the melted low melting temperature metal element 25. The insulating tubes isolate the separated parts of the low melting temperature metal element 25 from each other to break an overcurrent applied to the varistor element 21 without an arc discharge.

Filed: 1995-06-26
Abstract: PURPOSE: To calculate accurately a position of a mobile station without provision of a specific GPS device to the mobile station and to reduce the information amount to be sent from a base station to the mobile station in this case. CONSTITUTION: A GPS device 23 of a base station 2 receives a signal from plural GPS satellites to measure the position, an arithmetic device 24 calculates error information from the position information and stored true position information and sends the error information to the mobile station and the arithmetic unit 44 of the mobile station 4 calculates the position of its own station based on the position information measured by the GPS device 43 of its own station and the error information. As a result, the position of its own station is accurately calculated without provision of a special GPS device in the mobile station 4. Since the position is calculated by two sets of information as longitude and latitude, the information amount sent from the base station 2 to the mobile station 4 is reduced.

Title: Forming method for high-resistance layer of gallium arsenide
Inventor: KOUZU HIDEAKI
IPC: H01L21/265
Filed: 1981-10-06
Abstract: PURPOSE:To prevent high-resistance layer from being of low resistance due to heat treatment, to remove an impediment, such as exudation to any region other than a desired region, due to a large diffusion coefficient, and to maintain the high-resistance layer even after the heat treatment of high temperature, by implanting boron ions into an N type GaAs substrate. CONSTITUTION:A layer with implanted ions is formed in a desired region on an N type GaAs substrate by implanting boron ions in a dose quantity of five times or more of the sheet carrier density of the substrate, and the surface of the N type GaAs substrate is coated with an insulation film. Thereafter, the substrate is subjected to heat treatment in an ambience under a prescribed pressure of arsenic, and thereby a high-resistance layer of N type GaAs is formed. The figure shows the relations of the ratio (separation resistance ratio) between the resistance of the layer with implanted boron ions and the resistance of a layer without implanted ions, to the dose quantity and to the temperature of heat treatment (for 15min in an ambience of nitrogen at a prescribed temperature). It is apparent from this figure that the quantity of boron ions implanted for maintaining the high-resistance layer even after the  heat treatment at a high temperature of 700 deg.C or above is about five times larger than the sheet carrier density of the substrate. The injection of boron may be reduced by a prescribed quantity when the temperature of heat treatment is low.

Abstract: PROBLEM TO BE SOLVED: To prevent malfunction by static electricity and generation of signal error by releasing static electricity generated on a headphone jack to a supporting frame to prevent generation of malfunction and signal error by static electricity. SOLUTION: In a supporting frame 13 of a PCB15, a receiving portion 30a of a headphone jack 30 is exposed to the outside through the through holes 13b, 14b of the supporting frame 13 and front panel 14, a ground terminal GND 30 of the headphone jack 30 is loaded on the PCB15 with its end portion being in contact with a projected portion 40 arranged at the lower surface of the PCB15 for the electrical connection. Thereby, if static electricity is released to the headphone jack 30, static electricity flows into the supporting frame 13 as indicated by a broken line via the projected portion 40 from the GND terminal 30b of the headphone jack 30 to prevent that static electricity flows into the PCB15. Therefore, generation of erroneous operation at the driver resulting from static electricity and signal error can be prevented.
