Title: Lock-up mechanism
Inventor: SHIBAYAMA NAOSHI
IPC: F16H45/02
Filed: 1989-10-03
Abstract: PURPOSE:To obtain a necessary and sufficient damping frictional force by providing such an arrangement that a lock-up clutch piston and a turbine member are frictionally engaged with each other by the friction force which is increased as a differential pressure between a fastening hydraulic chamber and a release hydraulic chamber increases. CONSTITUTION:A frictional force generating means 27 frictionally engages with a lock-up clutch piston 20 and a turbine hub 17 by a friction force which depends upon a differential pressure between a fastening hydraulic chamber and a release hydraulic chamber 23. Accordingly, when the lock-up pressure is built up while the hydraulic pressure in the release hydraulic chamber 23 starts dropping, a differential pressure between the fastening hydraulic chamber 22 and the release hydraulic chamber 23 is produced so as to press the lock-up clutch piston 20 against a cover 13 in order to produce a pressing force, and accordingly, a lock-up facing 25 initiates power transmission between the cover 13 and the lock-up clutch piston 20. Simultaneously with this initiation, the frictional force which increases as the differential pressure between the lock-up clutch piston 20 and the turbine hub 17, is generated. Accordingly, it is possible to obtain a necessary and sufficient damping frictional force.

Title: Picture forming device
Inventor: MAEJIMA KATSUYOSHI
IPC: H04N1/40
Filed: 1989-10-03
Abstract: PURPOSE:To form a moving picture without blur and to form a still picture with high resolution by outputting a picture data by one field in a picture signal and a picture data by one frame switchingly. CONSTITUTION:A picture data from a conversion means 1 is led to a picture forming means 2 with a switching means 204, and when the picture is formed based on the picture data, the conversion means 1 outputs a picture data by one field in a picture signal and a picture data by one frame switchingly. Thus, when the picture signal inputted to the conversion means 1 represents a moving picture, the picture data by one field is outputted and when the picture signal inputted to the conversion means 1 represents a still picture, the picture data by one frame is outputted with changeover. Thus, one moving pattern is formed without blur and a still picture is formed with high resolution.

Abstract: PURPOSE:To decrease the local abrasion of a cylinder liner and to prevent the seizure by radiating laser light whose energy density is high and welding a metal being excellent in wear resistance and seizure resistance to an area where the abrasion quantity is the largest on the inner wall surface of the cylinder liner. CONSTITUTION:A cylinder liner 1 is set to a rotation holding device 3, and by a preheating device 9, especially a top dead center area 2 of the cylinder liner 1 is preheated to a prescribed temperature. A laser radiating part 6 of a laser radiating device 5 is inserted into the cylinder 1, and a material being excellent in the wear resistance and the seizure resistance is brought to laser padding to the surface of the preheating part. The laser radiating part radiates a laser light, while moving at a prescribed speed, supplies a flux, and also, supplies a wire 8 for buildup welding from a wire supplying device 7. In such a way, the service life can be extended by welding a dissimilar metal, excellent in wear resistance and the seizure resistance, to the inside surface of the top dead center area 2 of the cylinder liner 1 by the laser light whose energy density is high.

Title: Image forming apparatus
Inventor: SASANUMA NOBUATSU
IPC: B41J2/52
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To provide an image with a high gradation without the cycle irregularity in the sub scanning direction even if there is the overlap with respect to an image with a low resolution by dividing an image signal into a high and low density areas and repeating the interval of forming picture elements in the recording medium feeding direction and/or in the perpendicular direction per each area. SOLUTION: A reflected light beam of a light source 3 from a manuscript 1 is focused by an optical lens 6 on a line sensor 7 such as a CCD, or the like so that an image in the main scanning direction is read out. With the optical system moved in the V direction for scanning, the image in the sub scanning direction is read out. A light beam received by the CCD is converted to the density scale as a digital signal. The non-linear part of the printer gradation characteristic is corrected and dots are thinned out with respect to the sub scanning direction in the low density area of the manuscript 1 so that it is converted into a vibration pulse width of a laser emission pattern capable of reproducing the area gradation.  Then, it is converted into A, B picture element groups arranged in the sub scanning direction by the LUT of A, B so that a latent image is formed selectively by a laser beam only in the low or high density area, respectively.

Title: Decarburization annealing method for grain oriented electrical steel sheet
Inventor: MIZUGUCHI MASAYOSHI
IPC: C21D9/46
Filed: 1989-10-06
Abstract: PURPOSE:To produce a grain oriented electrical steel sheet having excellent magnetic characteristics and stable surface insulating films by detecting a change in the compsn. of the gas in a decarburization furnace and controlling the amt. of decarburization and surface oxidation of the steel sheet at the time of decarburization annealing of the grain oriented electrical steel sheet. CONSTITUTION:The steel sheet 3 passes through the decarburization annealing furnace 1 and the wet gas contg. H2 is supplied from a supplying pipe 2 into the furnace to decarburize the C on the steel sheet surface to a prescribed grade by the H2O in the wet gas and to oxidize a part of Si in the steel sheet to SiO2 at the time of hot rolling, annealing and cold rolling of a high-silicon steel slab to a steel, then subjecting the sheet to the decarburization annealing. The amt. of the annealing of the steel sheet is estimated with high accuracy from the compsn. of the gas supplied to the decarburization annealing furnace 1 and the detected values of the H2O and CO in the gases discharged from a flue 5 of the decarburization annealing furnace 1. The amt. of the H2O in the supplied wet gas is then so regulated as to attain the desired amt. of the decarburization and the good-quality glassy insulating films are formed of an annealing and separating agent consisting of an MgO system and SiO2. The steel sheet is accurately nitrided by a difference in the components of the atmosphere gases before and after the nitriding in the same manner as in the case of the decarburization even when the steel sheet is thereafter nitrided by gaseous NH3 in a nitriding zone 8.

Title: Formation of dot
Inventor: IKUTA KUNIO
IPC: H04N1/405
Filed: 1984-12-07
Abstract: PURPOSE:To form dots without any complicate projections nor recesses at a peripheral edge by reducing each dot area on a virtual screen and shifting them at random. CONSTITUTION:Part of an undistorted (normal) unit dot area is so cut as to approximate a distorted unit dot area most. This small cut piece is determined by the quantity RX and RY of a position shift in the undistorted unit dot area and the density value at the screen coordinates P(x, y) in the distorted unit dot area is equal to the density value at the screen coordinates P'(x-PX, y-PY) in the undistorted unit dot area. For the purpose, the coordinates (x, y) are converted into (x-PX, y-PY) to obtain a distorted approximate screen pattern equivalently. Therefore, RX and RY corresponding to each unit dot area in one array section consisting of, for example, 32X32 unit dot areas is calculated previously and written in memory device, and then the converting operation requires only by addition and is easily carried out.
