Title: Reverse image forming method
Inventor: MIFUNE HIDETSUGU
IPC: G03G15/22
Filed: 1987-09-18
Abstract: PURPOSE:To easily and surely form a reverse image by using a copying machine in a normal image copying system, forming a toner image corresponding to an original image on a colored transfer sheet with white toner and performing copying on a white transfer sheet with black toner by setting an obtained copied substance as an original. CONSTITUTION:A developing device incorporating the white toner is fitted in a copying machine main body and colored paper is used as a transfer sheet. By performing an electrophotographic process, white toner image corresponding to the original image is formed on the colored paper. Then the colored paper where the white toner image is formed is placed on an original platen and the developing device is exchanged for the developing device incorporating the black toner, and copying is performed by using conventional white paper as a transfer sheet. If the exposure of image is performed on the colored paper in such a state, charges on a photosensitive body are removed and the toner is not made to adhere on a part where the white toner image is formed. Meanwhile, the charges on the photosensitive body are not removed and the toner image is formed on a background part (colored part) because it can not obtain reflected light. Thus, the reverse image of the original image can be obtained without necessitating a special device or a control mechanism.

Title: Fluid cutoff valve control method
Inventor: SUGA YUKIO
IPC: F16K31/04
Filed: 1991-09-17
Abstract: PURPOSE:To reduce the extent of power consumption in a device by controlling the driving motor speed of a fluid cutoff valve such as a gas cutoff valve or the like. CONSTITUTION:In a motor driving type gas cutoff valve, since gas pressure is so large at time of valve opening (or closing), in order to get a motor thrust, motor's rotational speed is delayed to sane extent and, after the elapse of the specified time, it is accelerated into constant revolution, and further at time of valve closing, a driving part 5 is operated by a microcomputer 4 so as to rotate the motor at constant speed in equi-pulse width, through which rotational control over a driving motor 1 is performed. With this constitution, a span of impressed pulse time becomes shortened, thus power consumption is reducible in this way.

Filed: 1992-09-04
Abstract: PURPOSE:To provide a high quality by forming a pleat-shaped protrusion in a surface of a holding member, brought into contact with an outer ring of a bearing, so as to improve the production efficiency, in a bearing device for a magnetic disk device. CONSTITUTION:A pleat-shaped protrusion 2a is formed by cutting work in a surface of a hub 2, brought into contact with an outer ring 3a of a bearing, by using a broach or the like. Other wise, a pleat--shaped protrusion-provided hub 2 may be formed by casting and molding. When a shaft 1 is press fitted to a bearing 3, a pressure only from the pleat-shaped protrusion 2a is received in the outer ring 3a, and it is secured to the hub 2 by this pressure. In this way, the pressure received by the outer ring 3a is reduced more than in the case of a uniform surface of the hub 2, to suppress deformation. Height and width of this protrusion 2a are changed so as to adjust force applied at press fitting time in accordance with a size of the bearing. The above work may be performed, or a pleat-shaped protrusion 1a may be formed in a surface of the rotary shaft brought into contact with an inner ring 3b of the bearing.
