Title: Treatment of substrate of resinous coating of roots rotor
Inventor: IWASE TAKAHIRO
IPC: F04C18/18
Filed: 1985-01-30
Abstract: PURPOSE:To enhance the adhesive strength between the substrate surface and a resin and to guarantee the strength even when the rotor is rotated at high speed by striking hard grains against the substrate at high speed, and then degreasing and washing with water before the resin is coated on the base material of a Roots rotor. CONSTITUTION:Hard grains such as steel ball shots are blown on a substrate surface 26 by compressed air to form much fine ruggedness, before a resin is coated on the base material of a Roots rotor 20. Then the contaminants such as fats and oils deposited on the substrate surface 26 are removed by a degreaser and washed, and the substrate surface 26 is showered to wash off the degreaser to obtain the clean substrate surface 26 and then dried. When the surface is thereafter coated, the bonding surface area of the substrate surface 26 is increased, the bare surface is exposed by grinding, and the bonding surface is activated. Accordingly, the adhesive strength between the substrate surface and the coating layer of the resin is enhanced and sufficient adhesive strength can be kept even when the rotor is rotated at high speed.

Title: Liquid-crystal display element
Inventor: ITO TAKAFUMI
IPC: G09F9/35
Filed: 1985-01-30
Abstract: PURPOSE:To make the formation of a defective picture-element hard and to improve the quality and yield of a liquid-crystal display by driving a liquid- crystal display element by an active matrix integration system and forming no picture-element electrode on its switching element. CONSTITUTION:The majority of the cause of a defective picture-element which is apt to be formed in the liquid-crystal display element driven by a active matrix lamination system is a leak due to a pinhole at the overlap part of a picture-element electrode and the switching element or the picture-element electrode and a wiring electrode. for the purpose, the picture-element electrode is changed in shape so that a gate line 1 does not overlap with the picture- element electrode 3, so the picture-element electrode is not formed on the switching element to prevent a leak between the gate line and picture-element electrode, thereby improving the quality and yield of the liquid-crystal display.

Title: Alkaline battery
Inventor: YOKOYAMA TAKAO
IPC: H01M2/08
Filed: 1992-01-31
Abstract: PURPOSE:To provide an alkaline battery which stays stable over a long period by using as a gasket material a composite material of a polyamide resin mixed with 20 to 30 weight percentage of alkali-proof engineering plastics. CONSTITUTION:A gasket 7 insulates and seals the openings of the positive electrode container 1 and the negative electrode container 6 of a battery. In addition, the gasket 7 is molded by mixing a polyamide resin with 20 to 30 weight percentage of an engineering resin having good heat and moisture resistance, for example, a polyphenyleneether resin (a PPE resin.) This consitition provides leaktightness even under severe conditions and eliminates the need of conditioning the humidity of the gasket 7 in assembling a battery sealing plate, reducing manpower by 20% and stabilizing quality characteristics. Alternatively, besides PPE resins, resins such as polyphenyleether, polycarbide, polyethylenetelephthalate, and polybutylenetelephthalate provide equivalent effects if a similar prescription is used.

IPC: G03G21/10
Filed: 1982-02-03
Abstract: PURPOSE:To improve the removing and collecting efficiency of a magnetic toner, by forming a cleaning brush from a magnetic fiber, and also magnetizing this magnetic fiber. CONSTITUTION:Against a magnetic toner To adhering onto the surface of a photosensitive drum 1, a slide-rubbing action by a cleaning brush 3 operates, and also the cleaning brush 3 is formed by a magnetized magnetic fiber 3a. Therefore, to the magnetic toner To, a magnetic action operates geometrically, too. In addition, the cleaning brush 3 is made to lightly press-contact with the surface of the photoreceptor drum 1 moving in the upper direction, therefore, to the magnetic toner To, a gravity action operates, too. As a result, said magnetic toner To is separated exactly from the surface of the photoreceptor drum 1. The magnetic toner To separated from the surface of the photoreceptor drum 1 drops downward successively by its tare, and is collected into a toner collecting vessel 5.

Abstract: PROBLEM TO BE SOLVED: To provide a method for expediting the detection of amplified DNA fragments after a sampling stage and PCR. SOLUTION: The E. coli O157 strains in a sample of food, drinks, etc., are collected by adding water to this sample, subjecting the sample to a homogenization treatment and mixing the sample with the magnetic particles coated with an anti-O157 lipopolysaccharide antibody.

The sample is then suspended in sterilizing water and is washed and thereafter, the sample is again put into the PCR reaction vessel, into which a reaction liquid (PCR reaction liquid) for amplifying a gene contg. FITC-dUTP is put to effect the PCR reaction.  If the E. coli O157 strain contg. a Verotoxin gene is included in the sample, the FITC-dUTP is taken into the DNA chain, by which the degree of polarization of fluorescence increases and, therefore, the presence of the E. coli O157 strain contg. the Verotoxin gene may be detected from the value of the degree of the polarization of the fluorescence.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To realize the image pickup device in which charges are transferred efficiently in the case that a vertical blanking period is short like that of a video signal for an advanced TV(ATV). SOLUTION: Photoelectric conversion elements 1 are arranged horizontally and vertically in a matrix, charges produced from the elements 1 are read and transferred in a horizontal direction by a horizontal transfer CCD 2. A storage section 3 stores the charges transferred by the horizontal transfer CCD 2. A vertical transfer CCD 4 reads charges stored in the storage section 3 and transfers them in the vertical direction. A memory circuit 5 rearranges and outputs the charges transferred by the vertical transfer CCD 4. After the charges are transferred horizontally in one field period, they are transferred vertically, then it is possible to decrease the transfer speed of the charges to the storage section 3 and then the characteristic such as a dynamic range is improved.

Title: Radar display
Inventor: USUI RYUSABURO
IPC: G01S13/89
Filed: 1989-01-26
Abstract: PURPOSE:To prevent a symbol from being worm-bored in image composition by comparing the brightness level of a radar image with the brightness level of the symbol, and setting priority according to the comparison result and switching the displays of the both. CONSTITUTION:A comparing circuit 11 compares display data on the symbol read out of a symbol display frame memory part with radar image data RD read out of a radar display frame memory part and generates an output signal corresponding to the large-small relation between their brightness level. Respective registers 12 hold data SD and RD and the output signal of the comparing circuit 11. A switching circuit 13 switches the data DS and RD held in the registers 12 with the output signal of the comparing circuit 11 held in the register 12. Then when the brightness level of the radar image and the brightness level of the symbol are different, an image with a high brightness level is displayed preferentially. When the brightness levels are equal to each other, an image with high priority is displayed, so the symbol is never worm-bored in the image composition.
