Filed: 1988-07-28
Abstract: PURPOSE:To smoothly rotate a holder and to prevent an image carrier and developing units from being vibrated unnecessarily by moving the developing units in a direction away from the image carrier when the holder is rotated and shifting a rotor in a direction away from the developing units. CONSTITUTION:The image forming device is provided with the holder rotatably placed near the image carrier 2, plural developing units 23 movable in the direction in which they move toward or away from the image carrier 2 disposed along the rotating direction of the holder, and the rotor 43 imparting driving force to the developing units 23. When the holder is rotated, the developing units 23 are moved in the direction away from the image carrier 2, and the rotor 43 is also moved in the direction away from the developing units 23. As a result, the developing units never abut on the image carrier and the rotor when the holder is rotated, whereby the holder can be rotated smoothly. In addition, the image carrier and the developing units are never vibrated unnecessarily.

Title: Processing agent for sodium hypochlorite
Inventor: ETO SATONOBU
IPC: C01B11/06
Filed: 1989-07-19
Abstract: PURPOSE:To make an aq. sodium hypochlorite soln. harmless by only sprinkling the processing agent over the soln. to cause a reaction as well as to prevent the fluidization of the soln. by combining a sodium hypochlorite reducing agent and a gelling agent for the soln. CONSTITUTION:The processing agent consists essentially of a hypochlorite reducing agent and a gelling agent for an aq. sodium hypochlorite soln. When a gel stabilizer consisting of a polyvalent metal salt is added to the composition, the gel stability is enhanced by the polyvalent ion in the stabilizer. Hence the gel state is maintained for more than several to several ten hours, the reduced material can be treated by a scoop, and the subsequent handling is extremely facilitated. A highly water-absorptive polymer based on PVA/polyacrylate, starch/polyacrylate, etc., is preferably used as the gelling agent. Meanwhile, calcium hydroxide, calcium carbonate, calcium chloride, aluminum hydroxide, etc., are exemplified as the gel stabilizer.

Title: Amplifier circuit
Inventor: KANEKO AKIRA
IPC: G05F1/585
Filed: 1993-06-30
Abstract: PURPOSE:To suppress switching loss by driving two FET elements in an H-type output amplifier circuits based on the logical product of outputs from a PWM circuit and a voltage comparator thereby conducting two FET elements on a diagonal out of four FET elements in the H-type output amplifier circuit.

Title: Calibrating device for reference reception signal generating device for synthetic aperture radar
Inventor: KIRIMOTO TETSUO
IPC: G01R31/00
Filed: 1981-11-20
Abstract: PURPOSE:To determine whether the varation of a reproduced picture of a body to be tested is caused by the abnormality in the operation of the body or by the distortion of a standard signal, by detecting quantitatively the distortion generated in the standard signal. CONSTITUTION:A correlative processing device 16 reproduced a picture by using video signals MI (t) and MQ (t) transmitted from a reference reception signal generating device of a synthetic aperture radar, and a reference function h (t) generated from a reference function generating device 15. The reference function is a function which is determined primarily by the flying conditions of a flying body, the radar elements of the synthetic aperture radar, etc. When the operation of a radar, a body to be tested, is normal, the picture in a picture reproducing device 17 and the picture of the radar to be tested are identical. On the other hand, when the body to be tested has any factors generating distortion, the above two pictures are different from each other. This difference is quantified by a data analysis computer 19.

Title: Draw forming method and die therefor
Inventor: YAMANAKA NAOKI
IPC: B21D22/20
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To enlarge clearance for a bead vertical wall by draw-forming a material with the material held by a blank holder with a drawing bead formed on its holding surface and by its opposing die. SOLUTION: At least a part of bead 1 becomes non-parallel to parallel lines, in a drawing profile (outside profile 2 of the lower die), therefore, in the inside profile 3 of the cushion ring. Draw-forming is performed with a material held by the blank holder 6 and the opposing die 5, the blank holder 6 being formed on its holding face with a drawing bead 1 having that non-parallel continuous bead part. Consequently, a bead resistance can be increased without tightening the clearance for the bead vertical wall, while that clearance can be enlarged if the bead resistance is kept constant.

Filed: 1983-10-08
Abstract: PURPOSE:To obtain a more simple inclined position adjusting means by inclining a casing until an engaging part fitted to a shaft is disengaged from a shifting member by an operation knob enabled to operate only in one direction. CONSTITUTION:When the casing 7 is to be inclined, the knob fitted to the right end of the shaft 13 is rotated in the arrow A direction and projections 16-16c are rotated in the same direction. When one projection 16 is inserted into the hole 20 of the shifting member 17, engaged with a lower end 20a and pushed downwards, the lower end of the shifting member 17 is put on a setting board 9 through a buffer member 19, so that the casing 7 is lifted together with a guide rod 22. Even if the casing 7 is separated from the operation knob at a required inclined position, the shaft 13 is not reversed because of the operation of one- way clatch. If the operation knob is rotated moreover in the arrow A direction to restore the casing 7 to the initial position, the projection 16 is disengaged from the lower end 20a of the hole and the casing 7 is returned to the setting board 9 by gravity.

Title: Display device employing color picture tube
Inventor: URATA HIROSHI
IPC: H04N9/28
Filed: 1990-07-17
Abstract: PURPOSE:To prevent mis-landing due to repulsion among electron beams by setting horizontal overlap among three electron beams to be a half of a radius of an electron beam in the horizontal directly or below to cause a different delay among the three electron beams. CONSTITUTION:An electron gun 6 is of in-line type and consists of a B electron gun 16, a G electron gun 17, and an R electron gun 18. Then a delay time 27 is given to the B electron gun 16 and a delay time gamma is set to the G electron gun 17 with respect to the R electron gun 18 as a reference, where gamma is a half of the radius of an electron beam on a panel in the horizontal direction. The three electron beams are subject to deflection scanning by a deflection yoke 7 mounted to the outside of a funnel 4. Thus, the three electron beams are not overlapped at the same time and then an orbit portion causing repulsion among the electron beams close to each other is remarkably reduced and a picture with excellent color purity is obtained even at a high brightness.
