Title: Whiteness control apparatus in rice refining machine
Inventor: HIRANO HARUCHIKA
IPC: B02B3/06
Filed: 1987-07-24
Abstract: PURPOSE: To facilitate machine operation by making it possible to correctly mill rice to set whiteness when the position of a moving element is set to meet the whiteness by a whiteness setting means, such as whiteness setting push button switch. CONSTITUTION: The white adjusting device has an elastic body, such as a reduction spring 12 or expansion spring, to impart pressurizing force on a resistor 11 and the moving element 19 for changing the repulsive force of the elastic body. The position of the moving element 19 is set to meet the whiteness by the whiteness setting means, such as the whiteness setting push button switch. A motor control means, then, operates to rotate a moving element motor forward or backward in accordance with the output thereof, thereby moving the moving element 19. The elastic force of the reduction spring 12 is then changed and the pressurizing force of the resistor 11 on the milled rice is so adjusted as to attain the set whiteness. Consequently, the easy and exact adjustment to the desired whiteness is made possible without relaying on intuition.

Title: Device for preventing collision of carrying truck
Inventor: HATANAKA HIROYUKI
IPC: G05D1/02
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To surely prevent collision even at the time of running plural carrying trucks running on the same track at a high speed. SOLUTION: Carrying trucks 12a and 12b acquire the relative distance to carrying trucks facing each other by their distance sensors 18a and 18b, and relative speed calculation parts of controllers 20a and 20b calculate the relative speed based on this relative distance. Based on the relative distance and the relative speed, discrimination parts of controllers 20a and 20b discriminate the case that there is not a probability that carrying trucks facing each other collide in a safe braking area because of the low relative speed and the small change of the relative distance or the case that there is a probability that carrying trucks facing each other collide there because of the high relative speed and the high reduction rate of the relative distance; and controllers 20a and 20b properly control the speeds of carrying trucks based on the discrimination result.

IPC: G03G15/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To make the service life of a photoreceptor prolonged by minimizing a discharge quantity by a main charger. SOLUTION: With respect to a non-image area forming no image so as to correspond to a part between paper sheets that the image is not formed in the surface of a photoreceptor drum 1, charging potential by a main charger 3 is lowered. In other wards, the photoreceptor surface is charged to potential lower than the specific high potential, and at the potential to the extent that the toner on a developing device 5 is not to stick on the photoreceptor surface, even when bias of the developing device 5 is 0 V. On the other hand, the bias voltage of the developing device 5, is made to 0 V, at the time of facing to the non-image area. In such a manner, on the non-image area, the discharge of the main charger 3 is reduced, and evolution of ozone and nitrogen oxides are reduced.  Moreover, the development bias with respect to the non-image area is made into 0, therefore the toner is restrained from sticking on the non- image area from the developing device 5.

Abstract: PURPOSE:To realize low power consumption and low heating and besides to prevent needless displacement of a piezoelectric element by a method wherein electric charges accumulated in the piezoelectric element are effectively returned to a power source, and the electric charges remaining in the piezoelectric element are effectively released in non-excitation. CONSTITUTION:In the case where, for instance, the invention is applied to a driving circuit of a piezoelectric actuator of a dot printer, a circuit as given in the figure is formed, a control circuit 55 intercepts a transistor (Tr)2 by indication of drive, and makes Tr1 conduct. After accumulating enough charges in a piezoelectric element P, Tr1 is intercepted, and Tr3 is made to conduct. A current made to flow to a coil 53 is damped, the stand by Tr3 is intercepted for displacement time necessary for printing, and Tr2 is made to conduct. Though charges accumulated in the element P flow through a closed loop, consumption as heat hardly exists. All electric energy accumulated in the element P is accumulated in a coil L as magnetic energy adjacent to the coil 53 after specific time. When Tr2 is intercepted at this instant, all the accumulated electric energy is returned to a dc power source 51 via a diode D1 by action of the coil 53.
