Title: Diffracted beam separation optical system
Inventor: SATO TAKEO
IPC: G03F9/00
Filed: 1987-09-25
Abstract: PURPOSE:To take out a beam intensity signal having a high S/N ratio using a high sensitivity detector having a large caliber, by once condensing diffracted beams approaching each other and subsequently changing the beam paths of the diffracted beams by a reflecting mirror having a sharp wedge shape. CONSTITUTION:When the first diffraction lattice 5 is formed on a mask 4 and the second diffraction lattice 7 is formed on a water 6 to perform the alignment of the mask and the wafer, the beam emitted from a laser 1 is split into two beam by a splitting prism 2 and incident to an illumination lens 3 to parallelly illuminate the diffraction lattices 5, 7. The diffraction lattices 5, 7 emit parallel diffracted beams approaching each other and these diffracted beams are once converged by a cylindrical lens 9 and subsequently reflected to photodectors separately by a reflecting prism 10 whose leading end is formed into a sharp wedge shape. By this method, the diffracted beam from the diffraction lattice 5 on the mask 4 and the diffracted beam from the diffraction lattice 7 on the wafer 7 can be separated and detected using the photodetectors 11, 12 each having a large diameter.

Title: Multiple functional starter
Inventor: TANAKA TOSHINORI
IPC: F02B67/00
Filed: 1983-12-19
Abstract: PURPOSE:To prevent an erroneous operation and improve reliability by providing a protecting means to prevent driving for a load at the time of starting an engine, on the delivery conduit line of an actuator. CONSTITUTION:A starter part 12 consists of a starter motor 13, a main switch 14, reduction gears 15, and a hydraulic pump 16. A hydraulic-pressure solenoid valve 10, as a protecting means of preventing driving for a load 5 at the time of starting an engine, is provided on the delivery conduit line 6 of a hydraulic pressure shifting devide 9. Although the hydraulic pump 16 is driven through the reduction gears 15 at the time of starting the engine, driving for the load 5 can be stopped at all times since the source voltage is connected and applied, due to the closing of a key switch 33, to the solenoid device 10b of the hydraulic-pressure solenoid valve 10 through wiring A, causing the delivery conduit line 6 to be connected to a return conduit line 4. Thus, any erroneous operation can be prevented, improving reliability.

Title: Semiconductor integrated circuit device with electric fuse element
Inventor: WATANABE YOJI
IPC: H01L21/82
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To stably detect a program/non-program state by charging between electrodes prior to a latching operation of detecting a resistance on continuity of an electric fuse element. SOLUTION: A predetermined time signal PRCH is held to a high level when a power source is turned on, thereby charging a capacity of an electric fuse element 10. At this time, if the electric fuse element 10 is in a non conduct state, a potential of a node n2 rises to a potential obtained by subtracting a threshold value of a charging transistor 15 from the level of the signal PRCH. On the other hand, if the electric fuse element 10 is already programmed and in continuity, a reach level of the node n2 becomes lower than when the electric fuse element is in non-continuity. Thereafter, the time signal PRCH is turned to a low level, a reset signal bRESET is returned to a high level, and a latch set signal SET is raised after a predetermined time has passed. A potential of a node n3 in latch circuits 18 and 19 is lowered by this operation if the electric fuse element 10 is in continuity.

Title: Polarization plane maintaining optical fiber
Inventor: NAGANUMA NORIHISA
IPC: G02B6/24
Filed: 1989-09-20
Abstract: PURPOSE:To easily specify a polarization plane maintaining direction by containing a fluorescent substance in a stress applying part. CONSTITUTION:The stress applying parts 26c consisting of a material having a thermal expansion coefficient different from that of clads 26b are included in the clads 26b arranged on both the sides of a core 26a and the flurescent substance is contained in the stress applying parts 26c. In the case of connecting a wavegide optical device to the polarization plane maintaining optical fiber 26, a fiber core 26d is arranged so as to be rotated, opposed to the optical device and irradiated with white light from the side of the core 26d. Since the stress applying parts 26c are emitted by the action of the flurescent substance, the polarization plane of the fiber 26 can easily be allowed to coincide with the polarization plane of excitation light and optical coupling efficiency can be maximized.

Title: Cleaning device for image forming device
Inventor: NAKAZAWA NOBUO
IPC: G03G21/10
Filed: 1988-09-29
Abstract: PURPOSE:To prevent toner from falling in drops and clogging and to obtain a stable cleaning operation for a long time by allowing a magnetic roll to travel in a forward direction with respect to an image carrier and to travel at a lower speed than that of the image carrier. CONSTITUTION:The toner which reaches the blade 3 of a cleaning device 2 is scraped and drops on the magnetic roll 4 and reaches a control member 6 according as the magnetic roll 4 turns. A part of the toner is attracted to the roll 4 to form a magnetic brush and reaches a position near the photosensitive body 1 again and rubs the surface thereof. Moreover, it reaches the blade 3 by being accompanied with the rotation of the roll 4 and the photosensitive body 1 and is supplied to the blade 3 as lubricant. An amorphous silicone is used for the phtoosensitive body 1 and the roll 4 is allowed to travel in the forward direction with respect to the surface of the photosensitive body. At such a time, in the case that the circumferential speed of the roll 4 is 1/2 speed of the photosensitive body 1, the toner does not drop but the toner held by the roll 4 rubs the photosensitive body 1. Then, the lower the circumferential speed of the roll 4 becomes, the larger, a usable area becomes.

Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain high torque at fully-open and fully-closed times, when a torque motor actually requires torque. SOLUTION: A rotatable rotor 5-1 and at least one magnetic force source are integrally built in with a magnetic path in-between. Magnets 6-3 and 6-4 having integral or separate north poles and south poles magnetized in opposite directions are placed on the rim of the rotor 5-1, and three magnetic pole pieces 9 to 11 are placed at the rim of an opening with the rotor 5-1 placed therein with the two adjacent magnetic pole pieces coupled with each other through coupling paths to form a torque motor. In this torque motor, both the ends of the magnets 6-3 and 6-4 are relatively thickened by thinning their central portions on the side in contact with the rotor 5-1. That is, a thickness l2 of both the ends of the magnets 6-3 and 6-4 is relatively increased by reducing a thickness l1 of their central portions on a side, where the magnets are in contact with the rotor 5-1, and thereby a magnet shape suitable for driving throttle valves is obtained.
