Filed: 1994-11-07
Abstract: PURPOSE: To surely perform focusing adjustment, to secure operability and to efficiently perform focusing operation by detecting the light that a projected indicator is reflected on an object to be inspected and a focal position based on the detected result. CONSTITUTION: An infrared projecting indicator emitted from an infrared light emitting element 13 is reflected toward an operating part P by means of a mirror 16 through a light emitting optical system 14 and reaches the operating part P through an objective optical system 9 with variable focal distance. The infrared projecting indicator reflected on the operating part P again forms the image on the light receiving surface of a photoelectric conversion element 18 through the objective optical system 9 with variable focal distance again. A received light quantity arithmetic circuit calculates the light quantity of the reflected beam of the infrared projecting index on the light receiving surface of the photoelectric conversion element 18 and compares it with a reference value stored in a memory.  An emitted light quantity setting circuit calculates the reflectivity of the operating part P and an infrared light emitting quantity appropriate to the focusing operation within a limit that does not affect a human body based on the reflectivity.

Title: Tool chuck
Inventor: NAKAMURA DAIJIRO
IPC: B23B31/12
Filed: 1989-10-19
Abstract: PURPOSE:To fasten a chuck by a manual force without using a chuck handle with a compact arrangement by providing such an arrangement that a manual torque is amplified by a mechanism in which an input ring, a stationary ring and an output ring are formed in a ring-like shape, and loosening is prevented by mesh urged by a resilient member. CONSTITUTION:No load caused by clamping of a tool 10 is applied to chuck pawls 12 at the initial stage of rotation of a manipulation ring 18 so that an output ring 20, an input ring 21 and a stationary ring 22 are rotated as one unit body so that the rotation of the manipulation ring 18 directly rotates a thread ring 15 which therefore feeds the pawls 12. When the pawl 12 makes contact with the tool 19 so as to apply a load, the output ring 20 and the input ring 21 push the stationary ring 22 rearward so that pressure contact surfaces 28, 29 are pressed against each other while balls 25 roll, and accordingly, the input turns into a high torque output which is then transmitted to the output ring 20 so as to clamp the tool 19. When the tool 19 is removed, by rotating the manipulation ring in a loosening direction, the pawls 12 is loosened so that a backlash of the thread ring 15 is eliminated, and accordingly, a resilient ring 33 pushes back the stationary ring 22 so that the press-contact between the pressure contact surfaces 28, 29 are released. Thus, a torque-up mechanism 17 is released so that the thread ring 15 loosens the pawls 12 in cooperation with the manipulation ring 18.

Title: Laminated ceramic piezoelectric body
Inventor: FUJII AKIRA
IPC: H01L41/083
Filed: 1986-11-17
Abstract: PURPOSE:To prevent the cracking and breakdown of an insulating plate and a ceramic piezoelectric plate generated during use, and to improve durability by disposing a dummy plate constituted of a metal having high rigidity between the base selection of a casing and the insulating plate. CONSTITUTION:A dummy plate 3 is organized of a metal having quality having high rigidity such as S45C, SUS304 or the like, and the hardness of the dummy plate is set at a value (approximately HRC 14-54) lower than that of a casing 5. Load applied to a ceramic laminate 1 is supported and fixed by the base section 5a of the casing 5 through an insulating plate 2 and the dummy plate 3. That is, reaction force by the load works on the dummy plate 3, the insulating plate 2 and the ceramic laminate 1 in succession from the base section 5a. Since the dummy plate is disposed between the base section 5a and the insulating plate 2, however, the projection of a contact surface 5b is absorbed by the dummy plate 3. Accordingly, durability is improved largely.

Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To improve stabilization of a torque in a low speed region and radiating effect of a frictional heat so as to suppress torque ripple at the time of low speed rotation by changing electromagnetic powder into a magnetic fluid. SOLUTION: When a magnetic fluid 12 formed by mixing magnetic powder with a fluid having viscosity is pushed from a magnetic fluid filling port 11a2, the magnetic fluid 12 flows down to a space 16b through a narrow space 16B2 from right and left spaces. The magnetic fluid 12 is held in the narrow space 16B2 of an annular protruding part and in a narrow clearance 16B1 between 11c1 and 15b1 by action of a magnetic flux ϕ2 of permanent magnets 20a and 20b, and the role for sealing is executed. Magnetic powder in the magnetic fluid 12 of a part where the flux ϕ2 of the permanent magnets 20a and 20b is not acted is collected in spaces 16c1 and 16c2 around a cylinder 15a when current-carrying is carried out on a coil, deviation of magnetic powder components is suppressed in a low level, and fluctuation of a torque is suppressed in a low level.  It is thus possible to prevent deterioration caused by abrasion of sealing, and it is possible to use a device semi-permanently.

IPC: B41N1/06
Filed: 1990-10-12
Abstract: PURPOSE:To prevent linear and planar fogs by forming fine grooves extending in a direction across the circumferential direction of a gravure printing block at non-printing image parts on the surface of the block and not only forming these fine grooves but also abrading other parts except the fine groove parts to a given level or below in surface roughness. CONSTITUTION:Fine grooves 18 are formed on a block 15 in a direction across the circumferential direction of the block and, even in the case where a foreign matter 11 is held between the block 15 and a doctor 8, the foreign matter 11 is caught in one of the fine grooves 8 at the time when the fine grooves 18 pass under the doctor 8 by the rotation of the block 15, and is discharged in the rotational direction of the block from a gap between the doctor 8 and the block 15. Accordingly, printing defect due to a liner fog is not caused. Then, the surface of the gravure printing block 15 is abraded smoothly to the level of 0.08S or below in surface roughness so as to minimize and smoothen the protruding parts of irregularity of the surface. As a result, when the doctor scrapes off excess ink on the surface of the block, the doctor does not bounce up, and ink can be favorably scraped off so as to prevent a planar fog.
