Patent JP-S55116152-A (JP)
Title: Error detector
Inventor: NISHIHARA MASATO
IPC: G06F11/10
Filed: 1979-03-01
Abstract: PURPOSE: To make it possible to detect securely even an error occurring in a short time by providing a gate circuit which allows the output of a parity checker to pass through for a certain time and circuit which stores temporarily a parity-error occurrence output signal.  
     CONSTITUTION: When the total number of bits of logic "1" of data on data bus 1 is odd, partiy checker 2 outputs signal 3 of level "H" to NAND gate 14 as a parity error. Gate 14 is applied with strobe signal 13 of level "H" as long time as the rightness of data should be secured. Normally, reset signal 17 of level "H" is applied to the R terminal of RS-FF16, and no error signal is outputted from checker 2, so that while the output of gate 14 is held at level "H", that of FF16 will be at level "L". If a short-period error would occur at this time, the output of gate 14 changes into level "H" and the output of FF16 increases up to level "H", and even after the error disappears afterward, the output of FF16 is held at level "H", so that the error  occurring when the rightness of data is secured will be latched definitely.

Title: Manufacture of semiconductor device
Inventor: HORI ATSUSHI
IPC: H01L21/76
Filed: 1993-02-12
Abstract: PURPOSE:To provide a simple device-isolation formation step, by eliminating a step part while a gate electrode is formed, and ensure carrier movement at a high rate, along with a fine pattern without punch through in the pattern. CONSTITUTION:A silicon oxide film 2 is deposited on a single-crystal silicon substrate 1, and a part of the silicon oxide film 2 included in an active region is selectively removed. A single-crystal silicon film 3 is formed only in an active region in a selective epitaxial growth step. After a gate oxide film 4 and a gate electrode 5 are formed, arsenic ions are implanted into the single-crystal silicon film 3 to form an n<+>-type source 6a and an n<+>-type drain 6b on the single-crystal silicon film 3. An interlayer insulating film 7 is formed all over, and a contact hole is drilled to connect metallic electrodes 8a and 8b to the source 6a and drain 6b. Since there is no step part between the gate-electrode part and device-isolation part, a break in wire or a variation in width of the wire is prevented in a fine pattern.

Abstract: PURPOSE:To conveniently and efficiently denitrate an NOx-contg. gas by providing a treating vessel through which the gas is passed and arranging a zeolite with the layer of an azide compd. added with an acetate formed on its surface in the vessel. CONSTITUTION:A treating vessel 1 through which an NOx-contg. gas is passed is provided, and a zeolite 7 with the layer of an azide compd. added with an acetate formed on its surface is arranged in the vessel 1 to constitute the denitrator.

Title: Decoding device
Inventor: IMANISHI HIROSHI
IPC: H03M7/40
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To accept the next code string with one-shift operation by shifting a code that consists of high order N bits within two N bits that are connected after successively acquiring each code word of variable and fixed length codes of parallel input data of N bits to high order side by the number of bits, that is equal to value which adds each word length of variable and fixed length codes. SOLUTION: A high order filling shifter 23 shifts high order sixteen bits within thirty-two bits that combine parallel input data D1 and D2 of sixteen bits to be connected based on shift quantity M and outputs a code C1. An output controlling part 13A shifts the code C1 to a high order side, based on variable/fixed code length VCL/FCL and a code word VCW which are decoded by a variable length decoder 24. A shifter controller 27 supplies a quantity M, that is equal to addition value AD of those adders 25 to the shifter 23. By this means, the shifter 23 accepts the next code string with only one-shift operation and accelerates the operation.

Title: Power on reset circuit
Inventor: MONMA HIDEO
IPC: H03K3/356
Filed: 1980-02-29
Abstract: PURPOSE: To avoid the malfunction caused by the noise, by reducing the integrating resistance when the charging voltage of an integrating capacitor becomes to a certain level or higher.  
     CONSTITUTION: With a rise of the power supply voltage VDD, the capacitor C is charged via the transistor Q 1 . When the charging voltage increases up to the threshold voltage of the inverter I 1 , the inverter I 1  is inverted to turn on the transistor Q 2 . Thus the capacitor C is also charged via Q 2  to increase the charging time. At the same time, the transistor Q 2  functions as a pull-up resistance to eliminate an effect of noise as well as increase the resistance of Q 1 .

IPC: H01S5/00
Filed: 1988-02-05
Abstract: PURPOSE:To prevent abrasive sags from being produced as well as locate a bonding position of a laser device in a manner that it is not away from a package window of a semiconductor laser by machining a heat sink into such a configuration that a pair of protrusions are formed on the exit surface of a laser light beam so as to extend from the edge on the device bonding surface side of the heat sink to an edge opposite to the former, and then abrading the device bonding surface. CONSTITUTION:A heat sink 1 includes a pair of protrusions 6, 6 formed integrally on a surface 4 which has an edge 3 jointly with a device bonding surface 2, the protrusions extending from the edge 3 to an edge 5 located in opposition to the edge 3. The device bonding surface 2 of the heat sink 1 is abraded. Thereupon, although edges which are possessed jointly by the upper surfaces of the protrusions 6, 6 and the device bonding surface 2 suffer from abrasive sags, the edge 3 enjoys no such abrasive sags. Thereafter, the upper surfaces of the protrusions 6, 6 are abraded. Hereby, a distance 1 between a position 7 where a laser device is bonded and the uppermost portion of the heat sink 1 can be shortened.

Abstract: PURPOSE: To obtain positive-positive and negative-positive copying images through changing over  of charging polarities by forming the intermediate insulation film of the electrophotographic receptor comprising subsequently laminating an intermediate layer, photoconductive layer and surface insulation layer on a conductive substrate by using oil-modified polyurethane resin.   
     CONSTITUTION: An intermediate layer 2 is formed by oil-modified polyurethane resin (clear for  floor made by Nippon Paint, etc.) to a film thickness from 0.1 to 20μ on a conductive substrate  (Al plate or the like) 1, on which a photoconductive layer 3 of amorphous Se or the like is  formed to a thickness from about 5 to 200μ, and further a surface insulation layer 4 of high resistance and abrasion resistance such as of polyester is formed, whereby the photoreceptor is  made. The layer 4 of this photoreceptor is subjected to primary charging to positive or negative  by a corona charger 5, thence to uniform exposure 6 then to the secondary charging at the polarity opposite from the primary one with a corona charger 7, after which it is subjected to the  image exposure 9 of the line original 8, whereby the positive images are made in case the primary  charging is positive and the negative imges in case it is negative, the latter owing to the peripheral  electric field effect. The negative images are effective for line images in this case. The formation  of the negative images of wide region images simply necessitates the use of developing electrode.

Abstract: PURPOSE:To prevent the generation of dead space where liquid remains near the lower part of the diffusing appliance by installing a diffusing appliance discharging bubbles into liquid in the lower part of a vessel and vertically installing flow guide plates with their lower part allowed to come near the bottom face of the vessel on both sides of the diffusing appliance. CONSTITUTION:A diffusing pipe 2 is arranged in a purifying tank 1 on the inner bottom side. When air supplied through an air pipe 3 from the diffusing pipe 2 is discharged as bubbles into sewage water W in the purifying tank 1, convection as shown by an arrow A is generated in the sewage water W to purify it by aeration. In this case, flow guide plates 4, 4 formed in the shape of a plate are vertically installed with their lower end allowed to come near the bottom face of the tank on both sides of the diffusing pipe 2. The distance B between the flow guide pipe 4 and the tank bottom face is set at about 5-20cm. Thereby, when air is discharged from the diffusing pipe 2, convection is generated through the clearance B between the lower end of the flow guide plate 4 and the tank bottom face and dead space is not caused near the lower part of the diffusing pipe 2.
