IPC: F23N1/00
Filed: 1991-09-24
Abstract: PURPOSE:To provide a gas effluent prevention valve which is constituted so as to prevent any hunting due to the valve opening motion of a valve element. CONSTITUTION:A valve element 4, partitioning off the inside of a cylinder chamber 6 to both first and second cylinder chambers 7 and 8, is usually held in a state of being opened by dint of pressing force of a coil spring 22 installed in the first cylinder chamber secondary pressure P2 is taken in the first cylinder chamber 7, and usually this secondary pressure P2 is taken in the second cylinder chamber 8. When this secondary pressure P2 is suddenly dropped by an excess flow rate at the downstream side, the primary pressure is taken in the second cylinder chamber 8, and thereby the valve element 4 performs its valve closing motion against the pressing force of the spring 22.

Abstract: PURPOSE:To improve the conveying ability for and the electrostatic charging performance of toner and to prevent toner from falling and scattering by putting a particle agitating material which is larger in particle size than toner in a toner hopper. CONSTITUTION:The particle agitating material 10 which is larger in particle size than the toner is put in the toner hopper 8. The particle agitating material 10 has >=100mum particle size and is much larger than the toner 9, so it is cut off by an elastic blade 5 and not conveyed to a developing roller 2. The particle agitating material 10 can charges toner 9 being agitated electrostatically and preliminarily, and the toner is charged electrostatically to some extent before being carried by the developing roller 2. Consequently, the quantity of electrostatic charging of the toner conveyed to the developing roller 2 increases sufficiently and the falling and scattering of the toner are reduced.

Title: Object detector
Inventor: FUJITA NOBORU
IPC: G01V8/20
Filed: 1991-08-30
Abstract: PURPOSE:To delete the mechanical adjustment and detect the existence of a detected object accurately by arranging a plurality of photoreceiving elements continuously in line and forming a photoreceiving element group and outputting the photoeletric conversion powers out of each half as positive and negative outputs and calculating the difference. CONSTITUTION:In the case of non-existence of a parking car 4, the reflection light from the floor reflection surface 20 is condensed through an optical system to form a floor surface light point 21. Wherever the light point 21 may be formed in the photoreceiving surface, positive or negative voltage is output in analog according to the relative point, and so the mechanical adjustment of the photoreceiving surface point is not necessary. In the case of existence of a car 4, the incidence angle of the reflection light from the car reflection surface 40 is different, and so the point of the car surface light point 41 is formed at different point from the light point 21. Therefore, by comparing the positive output and the negative output from a photoreceiving elements group 7, the shift of the light point forming is detected and the existence of the car 4 can be detected.

Abstract: PURPOSE:To attain to enhance magnification by enabling the use of a high magnification objective lens having a rear side focus position therein, by providing a relay lens for relaying diffracted beam formed into an image by an objective lens to again form the same into an image. CONSTITUTION:Laser beam from a laser beam source 12 is converted to parallel beam by a collimator lens 13 to irradiate a regular pattern 11. When the regular pattern is irradiated with parallel beam, a diffraction phenomenon is generated and diffracted beam transmitted through the regular pattern 11 is formed into an image as a diffraction image, that is, a Forier conversion image by an objective lens 14. Because this image is formed to the rear side focus surface (f) in the objective lens 14, diffracted beam is relayed by a relay lens 15 and again formed into an image on a space frequency filter 16 to detect the flaw part of the regular pattern 11.

Title: Actuator for telescope
Inventor: SAKABE MOICHI
IPC: G02B7/182
Filed: 1986-10-14
Abstract: PURPOSE:To permit position control with high accuracy and to eliminate the need for a lubricating material by using magnets to constitute a contactless bearing thereby decreasing frictional force. CONSTITUTION:This actuator is provided with an actuator body for driving a mirror 3 of a telescope, a frame 2 which houses the actuator body at one end and has the 1st magnet 8 at the other end and a rod 1 which is inserted into the frame 2, has the 2nd magnet 9 repellent from the 1st magnet 8 in the position opposite to the 1st magnet 8 and is connected at the other end to the actuator body. The magnetic pole directions of the permanent magnets 8a, 9a are so disposed that the magnetic poles repel each other on an opposed gap surface. Since the rod 1 is always returned toward the central axis by the repulsive force on the gap surface, the position thereof is maintained. The rod 1 and the frame 2 are held without contact in the above-mentioned manner and, therefore, the position control is permitted with the lower frictional force and the higher accuracy. Since no lubricating materials are used, the contamination of the periphery is obviated.

Title: Duplex switching control system
Inventor: HATAYAMA SHIGEAKI
IPC: G06F11/20
Filed: 1989-09-20
Abstract: PURPOSE:To eliminate the need of the confirmation processing of a system at the time of turning on a power source by switching the system when a prescribed time elapses after receiving a notice of an inoperable state from the other system. CONSTITUTION:When an inoperable state of the own system is detected by an informing means 111 of the own system, a notice is executed to a notice receiving means 121 of the other system, and a switching instructing means 141 of each corresponding system actuates a timer 131. When a prescribed time elapses after the actuation of the timer 131, the switching instructing means 141 sends a switching instruction to a switching means 151, and the switching means 151 executes system switching to the system of a sending origin of this switching instruction. Accordingly, for instance, even in the case of a power source switch is turned off and both the systems come to an inoperable state, in accordance with an inoperable notice by the informing means 111 of one system, system switching to the other system is not executed immediately, therefore, it does not occur that the operation stops on the way of switching of the system. In such a way, the confirmation processing of the system at the time of turning on the power source becomes unnecessary.
