Title: Diversity receiver
Inventor: NIKAWA SUSUMU
IPC: H04B7/02
Filed: 1987-09-09
Abstract: PURPOSE:To attain sufficient response to fading by sampling and holding each output of logarithmic detection sections in a different sample timing, decoding it into a consecutive value of each branch, and outputting the result to a comparison section. CONSTITUTION:Sample-and-hold circuits 8a, 8b use a sample pulse DSa set at the latter half of an IF switching pulse TS and a sample pulse DSb set in the latter half of an inverse IF switching pulse TS alternately, the output of a DC amplifier 32 is sampled by switches SW3, SW4, the voltage is held by capacitors C1, C2 in case of the holding to decode the result into a consecutive output of each branch. Thus, even when one logarithmic detection section 3 is used in time division, the rise of decoding of an envelope detection signal from the sampling system to the continuous system is quickened, the fast fading is replied sufficiently and the interruption without time delay is detected.

Title: Arrester consisting of arrester element arrays and manufacture thereof
Inventor: OHASHI TAKASHI
IPC: H01C7/12
Filed: 1990-08-27
Abstract: PURPOSE:To enhance withstand discharge rating and to improve arrester performance by setting the ratio of arrester element arrays having lowest starting voltage and highest starting voltage within a specific range thereby making uniform the shunt ratio of surge current. CONSTITUTION:The ratio Sv between an arrester element array having lowest starting voltage VNmA (N=1-10) and an arrester element array having highest starting voltage is set to 0.98<=Sv<=1.0. Consequently, a lightning surge current or a switching surge current can be shunted uniformly to each arrester element array and an arrester having high withstand discharge rating can be realized. When a plurality of arrester element arrays having nonlinear voltage-current characteristics are arranged electrically in parallel, they are arranged selectively so that the ratio Sv between the arrester element array having lowest starting voltage VNmA (N=1-10) and the arrester element array having highest starting voltage satisfies a relation 0.98<=Sv<=1.0 for each arrester element array. According to the constitution, shunt ratio of surge current can be made substantially uniform for each arrester element array without requiring special high capacity measuring device.

Title: Arrangement optimizing display system
Inventor: OKADA KIYOSHI
IPC: G06F19/00
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To enable a network administrator to obtain an easy-to-understand display by compressing an M-dimensional space until the thickness in its coordinate axis becomes zero and displaying a group of objects which are rearranged in an N-dimensional space. SOLUTION: In the M-dimensional space, an arbitrary number of objects 10 are arranged. To display the arrangement of the objects 10 like this on, for example, a plane display, the objects 10 are arranged temporarily in a three-dimensional or more-dimensional space and after the arrangement is optimized, compression is carried out in a set axial direction, thereby replacing the three-dimensional arrangement with two-dimensional arrangement. In this case, the compression is performed while an object 10 at the left end is shifted slightly to the left. Thus, the compression and the optimization of distances between objects 10 are performed in parallel. Consequently, the intervals of the respective objects 10 viewed from the x-y plane are optimized and the thickness in the z-axis direction becomes 0.  Consequently, the arrangement of the objects 10 can be seen on the x-y plane by compressing the objects 10 arranged in the three-dimensional space along the z axis.

Title: Press processing of plastic
Inventor: HASHIMOTO TADASHI
IPC: B29C59/02
Filed: 1993-09-10
Abstract: PURPOSE:To improve a surface state and to prevent the shift of the surface of a raw sheet because molding is mode possible by a single heating and pressing operation by preliminarily providing an air venting continuous groove part to the surface of the raw sheet. CONSTITUTION:Air venting continuous groove parts 2 are preliminarily provided to a raw sheet 1 made of plastic and this raw sheet 1 is heated and pressed between hot plates. For example, when the raw sheet 1 with a thickness of about 1mm is produced by laminating two hard vinyl chloride resin sheets each having thickness of 0.5mm to press them, continuous groove parts each having a width of 0.2mm and a depth of 0.1mm are provided to the surface of the raw sheet 1 at an interval of 30mm by pressing a roll to the raw sheet 1 and this grooved raw sheetr is subjected to press processing. In this case, a hot plate is heated to 150 deg.C to press the raw sheet for 3min and subsequently cooled to 40 deg.C. When the continuous groove parts 2 are processed at the melting temp. of the raw sheet 1 or lower, molding strain is released when the raw sheet 1 is heated to processing temp. or higher and the continuous groove parts 2 have a tendency to disappear and, therefore, good surface properties are obtained.

Filed: 1982-12-24
Abstract: PURPOSE:To improve passenger service and to reduce the work load of a conductor, by detecting the position of a train, and making the passengers to observe the running position of the train by a line lamp and an indicator panel. CONSTITUTION:The present position of a train is detected by an on board position detector 1 and inputted to an input signal operating part 2 in an indicating device. The inputted data is computed, and the distance in kilometer of the train is computed and sent to an indicator lamp command part 4. A station name lamp 6 and a line lamp 5 are lighted in response to the distance in kilometer of the train. The present position of the train is indicated on a staion name and route indicator panel 7. The computed distance in kilometer is compared with the operation data, which is stored in a comparing part 3 in advance, and the hour and minute of arrival at the next station is computed and indicated on a next station arriving time indicator panel 8 at the front surface of the indicating device. In this way, passengers can know the position of the train and the time required to reach the next station all the time. Thus accurate information can be found. The present position of the train can be found even at night or when the train is delayed. Therefore the passenger service can be improved and the load of a conductor can be reduced.

Title: Semiconductor device
Inventor: YOSHIDA MIYOSHI
IPC: H01L21/60
Filed: 1984-10-27
Abstract: PURPOSE:To enable the stress at the junction caused by the variation in temperature of the titled device to be reduced by the deformation in the extension of a junction metal, by a method wherein a bump is bonded to the extension of a metal bonded to the wiring of the surface of a semiconductor chip. CONSTITUTION:When temperature varies, thermal strain generates between the semiconductor chip 1 and the package 7, and stress generates by the deformation of the junction between both. The strength of this stress depends on the amount of thermal strain and on the length of a part of deformation. But the extension of the junction metal 11 is capable of expansion and contraction: this part deforms. Therefore, the length of a part of deformation is the sum of the height of the bump 6 and the length of the expandable and contractable medium part of the junction metal 11, and so is larger only than the height of the conventional bump 6. The stress generating at the part of deformation is reduced, and the lifetime of the junction prolongates. Since the number of bumps 6 can be increased by reducing the volume, more electric functions than conventional can be accommodated in a semiconductor chip 1.

Title: Compound semiconductor selective dry-etching method
Inventor: UCHIYAMA HIROYUKI
IPC: H01L21/331
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To satisfy both anisotropy and selectivity and to make it possible to form a highly efficient thin-layered compound semiconductor element by a method wherein SiCl4 and fluorine gas, containing no carbon, are used as etching gas, and oxygen is utilized in etching. SOLUTION: SiCl4 gas, fluorine gas containing no carbon and oxygen are used as etching gas. As a result, the fluorine radical, which is formed on the surface of an etching stopping layer 14, is replaced with oxygen instantaneously, the selectivity ratio can be improved sharply using the surface of the etching stopping layer 14 as an oxide having a very large etching stopping effect. At the same time, as the quantity of residual fluorine is suppressed by the fluorine- oxygen substitution reaction, a stabilized device can be manufactured. Moreover, as a silicon oxide approximate substance, which can be easily removed by an aqueous solution of hydrofluoric acid, etc., is deposited on the sidewall of etching, the anisotropy by the sidewall protecting film can be improved.

IPC: C22F1/00
Filed: 1991-08-12
Abstract: PURPOSE:To prevent deterioration in baking hardenability by subjecting a sheet of Al-Mg-Si type Al alloy, having a specific composition and previously subjected to natural age hardening by means of air cooling after solution hardening treatment, to reversion treatment under specific conditions. CONSTITUTION:A sheet of an Al-Mg-Si type Al alloy which has a composition containing, by weight, 0.3-0.8% Mg, 0.5-1.0% Si, and 0.001-0.05& Ti and containing, if necessary, one or more kinds among 0.05-1.0% Cu, 0.05-2.0% Zn, 0.01-0.3% Mn, 0.01-0.2% Cr, and 0.01-0.2% Zr is subjected to solution hardening treatment and to air cooling to undergo natural age hardening. This alloy sheet is heated at the prescribed temp. in the range from 200 to 260 deg.C for a time shorter than the time necessary to minimize the hardness of the alloy sheet by means of heating so that Vickers hardness takes the value satisfying an inequality (where Hv0 means the hardness before heating, Hv1 means the hardness after heating, and Hmin means the hardness at the time when hardness is minimized). By this method, the subsequent natural age hardenability of the alloy sheet can be decreased and deterioration in baking hardenability can be prevented.
