Title: Control circuit for variable discharge pump
Inventor: SATOU YOSHITO
IPC: F04B1/26
Filed: 1978-07-28
Abstract: PURPOSE: Constitution of a variable discharge pump to be able to be controlled increasingly or decreasingly by a servo valve and a servo cylinder makes the discharge amount of the pump possible to increase or decrease in proportion to the operating strokes of a change-over valve to control to supply of oil pressure to an actuator.  
     CONSTITUTION: With increase of load to work on an actuator 4, when discharge pressure P 1  of a pump 1 has come over a setpoint PL in low pressure, if a pilot change-over valve 23 is controlled, as pressure P a  increased or decreased in proportion to the discharge pressure P 1  is increased or decreased in proportion to the operating strokes by a second control valve 36, pressure P c  supplied to a pilot pressured part 24 of a servo valve 19 increases or decreases in proportion to the operating strokes by taking the pressure P a  as the upper limit. And when the discharge pressure P 1  has gone up beyond high pressure setpoint PH, the discharge pressure P 1  is supplied to a third control valve 40, the valve 40 moves in the direction of decreasing the pressure resulting in dropping the pressure PC to the servo valve 19 and minimizing its discharge amount QC.

Title: Gypsum mold
Inventor: ARISHIRO TADASHI
IPC: B28B7/34
Filed: 1989-04-13
Abstract: PURPOSE:To perform an excellent mold releasing property by containing gypsum as a main ingredient and at least containing talc. CONSTITUTION:Talc should be added in a necessary quantity for making the mold releasing property excellent, however, since when the talc is added appropriately relative to the quantity of the gypsum, the strength of the gypsum becomes low, the upper limit should be set in view of this point. For example, it is preferred to set the talc to be 5 - 20pts.wt. with respect to 100pts.wt. gypsum. And, in the case of adding calcium carbonate in substitution of talc, the adding quantity of the calcium carbonate should be added at least in view of obtaining an excellent releasing property in the same manner of the case in talc, and the upper limit thereof should be set in view of the strength of a gypsum mold, moreover, should also be desirable to set in view of the prevention against the deterioration of an inner wall surface in the gypsum mold.

Title: Movable table device
Inventor: YAMASHITA KENKICHI
IPC: F16C29/00
Filed: 1984-05-10
Abstract: PURPOSE:To eliminate deviation of a retainer due to micro slips thereof by reducing an elastic displacement caused on a side wall by a preloading force applied to both side walls of a base platform from its inner side as it goes toward the axial end portion without depending on the moving position of a table. CONSTITUTION:The side wall 12 of a base platform 10 has a gentle slope at a right-hand ball 15B in a range wherein the ridigity on both ends of the side wall 12 and the deflection quantity is small and a sharp slope at a left-hand ball 15A. Therefore, the ball line deviates rightwardly. Conversely, in a case where the table 1 moves rightwardly and the ball 15B comes to the right end of the side wall of the base platform 10, the ball line tends to deviate leftwardly, and the retainer 20 constantly deviates toward the central direction. Therefore, micro slips of the retainer 20 are accumulated and large deviation of the retainer is not caused.

Title: Photoreceptor drum rotating mechanism and electrophotographic device using the same
Inventor: SUZUKI MASAHITO
IPC: G03G15/00
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To enable stably driving a photoreceptor drum, easily and surely achieving ground, and improving an assembling performance by constituting so that a thrust into the photoreceptor drum bore surface is executed, without a flange member, and a shaft fixing and rotation of the photoreceptor drum is performed. SOLUTION: When this mechanism is about to rotate the photoreceptor drum 1 clockwise, a master gear 3 mounted on a driving shaft 2, rotates a pinion gear 4 counterclockwise. Since a pinion gear 4 moves a rack 5 in the direction of the arrow so as to press the drum 1, a top part 6 of the pinion rack 5 comes into internally contact with the drum 1 bore so as to stick thereon, and the photoreceptor drum 1 begins to move integrally with the driving shaft 2 by the friction. Accordingly, since the photoreceptor drum 1 is not provided with a flange for solidly setting, and conductive material is adopted for the drum receiving member, the ground is made to be easily and surely achievable, and the scratch to the photoreceptor at the assembling time or the like can be prevented.
