Title: Manufacture of solid electrolyte type fuel cell
Inventor: KAKIGI MUTSUO
IPC: H01M8/02
Filed: 1992-12-22
Abstract: PURPOSE:To reduce gas permeation in an electrolyte film, and improve power generating efficiency and a fuel utilization factor by sealing a surface layer of the electrolyte film while using ion implantation or using the ion implantation and sputtering film formation at the same time. CONSTITUTION:This fuel cell is constituted by laminating a base body tube 1, a fuel electrode 2, an electrolyte film 11 and an air electrode 4 in order upon each other, and the electrolyte film 11 is constituted of a low pressure plasma thermal spraying coating film 12 and an ion implantation film 13 whose surface is sealed by an ion implantation method. This electrolyte film 11 is constituted of this coating film 12 and the ion implantation film 13 whose surface layer is sealed by using ion impantation or using the ion implantation and sputtering film formation at the same time after the low pressure plasma thermal spraying coating film 12 is formed. Thereby, since the thin film type solid electrolyte film 11 which cannot be obtained by conventional mere low pressure plasma thermal spraying can be obtained, high power generating efficiency and a high fuel utilization factor can be obtained, so that fossil fuel consumption can be reduced and CO2 discharge can be reduced by improving the power generating efficiency.

Title: Distance measuring device for automatic focusing camera
Inventor: UENAKA YUKIO
IPC: G03B13/36
Filed: 1991-11-30
Abstract: PURPOSE:To improve the distance measurement accuracy by a correlation method by obtaining a large step difference in the voltage level of an image signal by increasing the voltage level of the image signal from a photodetecting sensor at the time of low contrast of an object to be photographed. CONSTITUTION:A subtracter 4 calculates the difference of an output voltage of a dark monitor sensor DM and a reference voltage and sets it as the reference level voltage AGCo of a photodetecting sensor 1. A comparator 5 outputs a reversing signal at the time when the output of one of monitor sensors M1-M3 becomes larger than the reference level voltage AGCo. Based on this reversing signal, a central processor (AFCPU) outputs a charge accumulated before that time as an image signal from a line sensor consisting of a photodiode PD and a charge transfer device CCD. In the case an image signal is a low contrast, the AFCPU sets the reference level voltage AGCo to a correction level 2AGCo of two folds. In such a manner, the output obtained from the line sensor becomes about two folds and an electric level difference in the image signal is enlarged.

Abstract: PURPOSE:To enable detecting a plurality of gases by forming a plurality of gas adsorbent parts provided between a comb shape excitation electrode and a comb shape reception electrode almost vertically to the transmission direction of elastic surface wave as a stripe pattern with constant gaps. CONSTITUTION:Between a comb shape excitation electrode 2 and a comb shape reception electrode 4 on a piezoelectric base plate 1 surface, gas adsorbent 8 is formed as a plurality of stripe pattern almost vertically to the transmission direction of elastic surface wave 3. When a pulse voltage is given to a terminal 6, surface wave 3 is excited on the electrode 2, propagates on the base plate 1 surface and is received by the electrode 4 and output from a terminal 7. If the gap of the stripe pattern of the adsorbent 8 coincides with a half of the wave length of the surface wave 3, the output of the teminal 7 decreases. When the 8 adsorbs the detected gas, the degree of the decrease increases. If a plurality of kinds of adsorbents 3 are used, a plurality of gases are able to be detected independently with a single sensor. By this, gas concentration can be detected by gas adsorption by the gas adsorbent.

Title: Data packet filter operation method
Inventor: KRISHNAN P
IPC: G06F17/30
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To improve the performance of a data packet filter, even when the number of rules required for realizing a security policy is increased. SOLUTION: This data packet filter stores the plural ordered rules 222 to be successively adapted to a reception data packet for realizing the security policy. The rules are automatically re-arrayed to improve the performance of the packet filter. The rules to be more frequently matched to an incoming data packet are moved forward in order, and those which are to be less frequency matched to the incoming data packet are moved backward in order. When a certain rule matches with the packet, in order to permit the first rule to be matched with the reception data packet to control a method for processing the packet, the remaining rules need not be evaluated. The data packet is matched with the rule at high speed by re-arraying the rules, and the performance of the data packet filter is improved.

Title: Electrolytic capacitor
Inventor: UCHIYAMA KIMIO
IPC: H01G9/12
Filed: 1989-12-28
Abstract: PURPOSE:To improve safety by coating the outer surface of a porous separator which is placed between electrodes selectively with a thermoplastic resin. CONSTITUTION:A separator 4 consists of a paper produced of Manila jute fibers or craft fibers and a coating layer consisting of a thermoplastic resin 6 is formed on the surface selectively in mesh. Then, when any abnormality occurs at the electrolytic capacitor and current increases abruptly, the thermoplastic resin 6 which is formed on the surface of the separator 4 produces heat, becomes flexible, is absorbed between the fibers of the separator 4 due to capillarity, and is expanded so that a wider part on the surface of the separator 4 may be covered. Thus, a part where an anode electrode 2 and electrolyte contact is narrowed and current is limited, thereby causing heat buildup to be restricted.

IPC: H01L29/812
Filed: 1992-12-24
Abstract: PURPOSE:To provide a semiconductor device of high reliability which can be easily manufactured without using fluorocarbon gas, and its manufacturing method. CONSTITUTION:An InGaP layer 2 is interposed between an N<+> type AlGaAs layer 10 and an N'' type GaAs layer 12 of a usual HEMT. In the case of etching using sulfuric acid and hydrogen peroxide or the like for forming a recessed part 14, the etching rate of the InGaP layer 2 is extremely smaller than that of the N<+> type GaAs layer 12. Hence when the N<+> type GaAs layer 12 is etched, the progress of etching can be interrupted in the vicinity of the junction surface of the layer 12 and the InGaP layer 2.

Title: Method of manufacturing semiconductor device
Inventor: TAKEDA KAZUHARU
IPC: H01L21/336
Filed: 1989-12-28
Abstract: PURPOSE:To reduce and hence simplify a manufacturing process by changing an incidence angle of ions and separately forming a source drain region where the concentrations of impurities are different from each other without forming a side wall oxide film of gate silicon. CONSTITUTION:Impurities are implanted into a substrate at a low concentration, which is being rotated at a specified slanting angle rather than vertically from above to the main plane of the substrate in a region 3 where the concentration of impurities is lower. Then, impurities are implanted into the main plane of the substrate from a vertical direction, thereby forming a region 5 where the concentration of impurities is higher. Heat treatment is applied to both the region 3 where the concentration of impurities is lower and the region 5 where the concentration of impurities is higher in order to recover crystal defect caused during implantation and to do electrical activation. This construction makes it possible to reduce and hence to simplify a manufacturing process.

Abstract: PROBLEM TO BE SOLVED: To obtain the equipment for soft hand-off capable of high speed processing by using an analog sample-and-hold circuit so as to hold a received signal and using a circuit employing a multiplexer to distribute the signals so as to realize substantially multiplication. SOLUTION: A matched filter circuit MFC1 has plural sample-and-hold circuits SH31-3n and an input signal Vin1 is given in parallel to the sample-and- hold circuits. Each sample-and-hold circuit provides an output of one-set of hold data to plural systems and an output of the SH 31 is respectively given to three multiplier circuits MULs 11-13. Since the matched filter circuit MFC1 uses one system of the sample-and-hold circuits SH31-3n to hold the signals for correlation operation for plural systems in this way, the entire circuit scale and power consumption is reduced more in comparison with the provision of a sample-and-hold circuit for each system and high speed processing is realized.
