Title: Formation of film on metallic base material
Inventor: OGAWARA TAKASHI
IPC: C25D5/04
Filed: 1988-03-16
Abstract: PURPOSE:To prevent a metallic member from being thermally deformed by heating or the like by burying a pit-shaped hole with metal and then forming a plated layer on the surface in case of the pit-shaped hole exists on the surface. CONSTITUTION:In case of forming a protective film on the whole surface of a metallic base material in which a pit-shaped hole 1a exists, when formation of the protective film is performed by build-up welding or a thermal spraying method of stainless steel, there is such possibility that the metallic base material is deformed due to excess heat imparted thereto. In order to eliminate this fault, build-up metal 10 excellent in adhesion for the base material is built up to the large parts in the pit-shaped hole 1a and thereafter metal 11 harder than the build-up metal 10 is built up thereon to form the same even face as the base material. Then, plating liquid 8 in a tank 7 is fed between a cathode consisting of the base material and an anode 2 moving thereon through a pipe 5 and both electrodes are electrified with an electric source 4 to form a plated layer 9 for the protective film. Thermal deformation of the base material is not caused by forming the whole protective film by plating, instead of build-up welding and a thermal spraying method.

CONSTITUTION:A wafer 5 is placed on a holder 3 and introduced into the reaction furnace 2 of the atmospheric CVD device 1 from a gate 6 part, the gate 6 is closed, and the gaseous SiH4 and N2O as the gaseous reactants are introduced into the furnace with gaseous N2 as the carrier gas and sent down on the surface of the wafer 5 from the small hole 9a of a distribution plate 9 to form an SiO2 film by CVD. In this case, since SiO2 particles are liberated in the furnace and deposited on the wafer 5 to damage its quality, the reacted gas in the furnace is sucked and discharged into an exhaust pipe 6b through many holes 6a provided on the inner surface of the gate 6. When the wafer 5 is discharged from the furnace 2, the gate 6 is opened, and the SiO2 particles in the furnace are sucked and discharged from many holes 13a of the exhaust plate 13 provided at the external upper part of the gate. As a result, SiO2 particles are not deposited on the SiO2 film on the wafer surface, and a high-quality wafer is produced with good productivity.

IPC: G02F1/1337
Filed: 1983-04-13
Abstract: PURPOSE:To obtain a controlling film for orientation having good regulating power for orientation, electrical insulating property and mechanical strength with a relatively thin film thickness by dispersing fine powder of an oxide in an org. high polymer film thereby forming the controlling film for orientation. CONSTITUTION:Fine powder of SiO2 having 50-200Angstrom  grain size is mixed with an org. solvent in which a polyimide high polymer is dissolved to prepare a coating liquid. Such liquid is printed by a printing method such as stamping on an electrode substrate 1 and is calcined. A controlling film consisting of the fine powder 7 of the oxide dispersed in the org. high polymer film 6 of polyimide is thus obtd. The surface which is in contact with a liquid crystal is the film 6 according to such structure and therefore the regulating power for orientation is strong. The controlling film for orientation has the pulverous powder 7 of the oxide in the film 6 and has therefore good mechanical and electrical insulating properties. Since the film 6 and the powder 7 are not divided to two layers, the formation of the film to a thin thickness over the entire part is made possible.

Abstract: PROBLEM TO BE SOLVED: To recognize an image with a proper size by correcting magnification errors. SOLUTION: Reference marks 40, 41 printed on a white reference part 24 of an original guide 21 at a prescribed distance in a main scanning direction are scanned and the interval between the reference marks 40, 41 is measured before reading an original on the basis of image data. The measured interval is compared with the design reference interval recognized by an image reader as the interval between the reference marks, and the output position of pixels in the main scanning direction is corrected on the basis of the compared result. Thus, the image is recognized with a proper size, without being affected by the magnification of an optical system changed with mounting errors.

Filed: 1990-03-16
Abstract: PURPOSE:To prevent a specific call classification from occupying all line groups to an outgoing path to effectively use lines by using all outgoing lines to the outgoing part for the call originated from its country and preventing the repeated call from another country from using them beyond a registered allowable frequency in use for repeated call. CONSTITUTION:A storage means (trunk call table) 3 where the allowable frequency in use for a prescribed call classification is stored for each trunk group number and a deciding means 4 which decides the call classification of an outgoing connection request call are provided. The call classification of the request call is decided by the means 4 at the time of requesting the outgoing connection; and when it belongs to the prescribed call classification and an allowable frequency (j) in use is set in the storage means 3, outgoing connection is allowed within the range of the allowable frequency (j). When the outgoing connection request call does not belong to the prescribed call classification, outgoing connection is allowed up to a number (i) of all lines of the outgoing path. Thus, repeating is prevented from occupying all line groups to the outgoing path to efficiently use lines.

Title: Speed control system of induction motor
Inventor: YAMASHITA NARIAKI
IPC: H02P23/16
Filed: 1982-04-19
Abstract: PURPOSE:To increase the torque in case a load is abruptly changed by a method wherein an output voltage is temporarily boosted by means of supplying a deviation voltage between speed command value and speed detection value as a correction voltage. CONSTITUTION:When the speed deviation due to abrupt change of load and the like is increased, the speed command value commanded by a speed setter 9 deviates from the speed detection value of a motor speed supplying output of a limiter circuit 12 with voltage, therefore the voltage and the command value V1 of frequency are changed by means of an adder 13 to be corrected. Besides the output voltage of the limiter 12 is made variable by means of a voltage divider 16 converting the output voltage V3 of the voltage divider 16 into the input voltage of the adder 17. Resultantly when the speed deviation due to an abrupt change of load and the like is increased. The torque of an induction motor 5 is temporarily increased by means of supplying the voltage.frequency command value V1 with voltage V3 as the voltage command value of a voltage V2 increasing the voltage of an inverter device and V/F ratio to increase the torque of the induction motor 5 temporarily.

Title: Position sensor housing mounting construction
Inventor: UCHIDA MASATO
IPC: B24B37/12
Filed: 1988-03-17
Abstract: PURPOSE:To improve the accuracy of a position sensor by loading a position sensor housing on a mounting fixed plate with the housing assembled on a fan-type elastic plate, thereby absorbing the displacement of the housing in the direction of thrust due to the lifting of a runner during the time of rotating a driving shaft, and preventing the looseness due to the radial displacement. CONSTITUTION:When a rotor rotates, the displacement of a runner 10 in the direction of thrust by a dynamic pressure bearing 8 is transmitted to a position sensor housing 32 through a driving shaft 16, while the displacement in the direction of thrust is absorbed by a fan-type elastic plate 62 consisting of an elastic body. The looseness due to the radial displacement of the runner caused by the rotation of the driving shaft 16 is also blocked by a mounting fixed plate 65 fixing an arm member 64 of the fan-type elastic plate 62 and a supporting bar of the mounting fixed plate 65. As a result, the accuracy of a position sensor incorporated in the position sensor housing 32 can be improved, and the mounting operation of the position sensor housing 32 can thus be simplified.
