Title: Superprecision surface working device
Inventor: YOKOYAMA RYOHEI
IPC: B23K15/00
Filed: 1990-09-28
Abstract: PURPOSE:To perform superprecision surface working by controlling acceleration of ion particles based on a measured result of surface roughness of a workpiece in angstrom order. CONSTITUTION:The surface roughness to be worked is measured by an interatomic power microscope 9 which is a measuring means capable of measuring the surface roughness of the workpiece 5 in angstrom order. Based on this measured result, the acceleration of ion outputted from an ion gun 14 is controlled and the ion articles are emitted toward a part to be measured of the workpiece 5. Consequently, when the part to be measured of the workpiece 5 is recessed, the ion particles are stuck thereto and when the part to be measured thereof is projecting, projecting part atoms are cut out by the impact force of the ion particles and the part to be measured can be made flat, hence the surface roughness to be worked can be made ultra-precision.

Title: Reference power supply circuit
Inventor: TAKIMOTO HISAICHI
IPC: G05F3/26
Filed: 1993-10-14
Abstract: PURPOSE:To improve the load drive capability by adopting a PNP transistor(TR) for an output TR and adopting emitter connection for the PNP TR so as to use a low voltage for a reference power supply circuit. CONSTITUTION:A PNP TR is adopted for an output TRQ10 in the reference power supply circuit. Thus, a minimum voltage of a power supply VCC at which the operation of the reference power supply circuit is possible is the sum of a reference voltage VREF and a voltage VCE between collector and emitter of the output TRQ10 that can make voltage of the reference power supply circuit lower. For example. Let the reference voltage be 1.8V and the collector- emitter voltage be 0.1V, for example, a voltage of 1.9V or over is enough for the voltage of the power supply VCC and the voltage can be made lower by a base-emitter voltage VBE of the TR. Since common emitter connection is adopted for the output TRQ10, load drive capability is excellent. Furthermore, Darlington connection is adopted for TRsQ10, Q11, a base current of the TRQ10 is set to be 1/hFE by the TRQ11.

Title: Optical shutter
Inventor: YAGI TSUKASA
IPC: G09F9/30
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To limit a shift amount of a half-wave length voltage in continuous driving to a minimum level to always maintain a light quantity constant in terms of a solid scanning type optical shutter using a PLZT as an optical shutter means. SOLUTION: An optical shutter forms an image on a photosensitive body by turning on or off multiple optical shutter elements for printing each consisting of a PLZT and passing the light therethrough when the optical shutter element is turned on. While a printing mode is effective, an electric field is switched to be in a ratio of non-inversion/inversion. Optical shutter elements for monitoring are provided adjacent to the elements for printing. Each optical shutter element for monitoring is driven by being switched between non-inversion and inversion states similarly to the element for printing. At a non-printing mode, a half-wave length voltage of the element for monitoring is measured, then a ratio of non-inversion/inversion of the electric field in the next printing mode is determined.

Title: Device for positive feed picking in fluid jet type loom
Inventor: TAKEGAWA YUJIRO
IPC: D03D47/34
Filed: 1990-09-27
Abstract: PURPOSE:To enable improvement in weft feeding efficiency with prevented occurrence of yarn breakage by operating a positive feeding mechanism during a period from start of picking to a time of unwinding a prescribed amount of weft before completion timing and positively feeding an accurate length of yarn. CONSTITUTION:An enging pin 7 is retreated with a controller 14 at a rotation angle corresponding to timing of picking start. Weft 2 in a stored state is then unwound from the outer periphery of a fixed drum 6 and an operation command is simultaneously sent to a rotation controller 15 after a prescribed time lag to drive a feed plunger 21. A roller 18 in a standby position is subsequently brought into contact with a roller 17 to nip the weft 2, which is then positively pulled out from the outer periphery of the drum 6 through the rotation of a servo motor 16 and delivered to a main nozzle 9. The plunger 21 is returned with the controller 14 on a sensed signal of a sensor 13, indicating the unwinding of the prescribed amount of the weft. The rollers 17 and 18 are separated to stop the operation of the positive feeding mechanism 12. The rotational speed of the serve motor 16 at this time is sufficiently lowered without causing a rapid change of tension in the weft 2.

Title: Pneumatic tire
Inventor: KOMATSU TATSUYA
IPC: B60C11/11
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To improve brake performance without increasing rolling resistance. SOLUTION: In this tire, by recessing side wall faces 18A, 18B along the tire circumferential direction of a block 18 in the circular arc shape, rubber volume near the side wall faces 18A, 18B is reduced, and therefore, neighbors of the side wall faces 18A, 18B easily expand circumferentially and radially of the tire even when rubber whose dynamic modulus of elasticity E' is high to improve performance of the first half of the brake. Therefore, even when tire circumferential side wall face neighbors separate from a road surface 22 for prior blocks due to slow return of the neighbors of the side wall faces, in this block 18, the neighbor of an end 20D of a tread 20 is still grounded, actual grounding area is larger than that for the prior block, and performance on the second half of the brake is improved.  Because brake performance can be improved without changing area (negative radio) of the tread 20, rolling resistance does not increase.

IPC: G05B19/18
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To make use of the advantage that working information about a working robot can be input based on numerical information and to apply the working information to practical working processes. SOLUTION: A jig 7 of a fixed shape is used which secures a workpiece 3a to the worktable 6 of a working robot as to one type of the workpiece 3a. With the jig 7 secured to the worktable 6, at least three predetermined points are visibly preset at positions appearing on the surface of the table. The coordinates of these predetermined points are input to numerical information in advance. To proceed with operations, the numerical information is sampled, position information is newly input as to the predetermined points from a true object, and coordinate transformation is performed so that position information preinput as numerical information coincides with the newly input actual position information about the predetermined points, thus controlling the working robot 1 based on the numerical information which has undergone coordinate transformation. Therefore, the number of processes for teaching can be reduced.

Title: Gas-filled discharge bulb
Inventor: KASAHARA MASATAKA
IPC: H01T1/14
Filed: 1987-10-14
Abstract: PURPOSE:To simply constitute a fail-safe mechanism and facilitate assembly by arranging a low melting point material interposed on the outer surface of a discharge bulb body by means of a resilient force of a plate spring. CONSTITUTION:In normal times, as the tip of a plate spring 18 secured to one electrode 14 is separated from the other electrodes 12a, 12b, the line electrodes 12a, 12b are insulated from a ground electrode 14. If a discharge bulb discharges continuously and is overheated due to some cause, a low melting point material such as solder 24 in contact with the outer surface of an insulation body melts, the plate spring 18 comes into contact with other electrodes 12a, 12b by its own resilience, and the line electrodes 12a, 12b are short-circuited to the ground electrode 14. As a result, the discharge of a gas-filled discharge bulb stops. This makes the constitution simpler and assembly easier.
