Title: Scanning device
Inventor: FUKAZAWA MOTOMU
IPC: G03B27/50
Filed: 1986-11-04
Abstract: PURPOSE:To obtain a reproduction image of high quality by moving a slit part arranged in front of a photosensitive body in synchronism with the scanning of a scanning mirror in such a direction that the quantity of the distortion of an image projected and formed on the photosensitive body surface is minimum. CONSTITUTION:The scanning mirror 5 is moved linearly for scanning as shown by, for example, a dotted line 51 so that the distance from the reflection point D of the main light beam of luminous flux to an ideal image surface 3 becomes equal to the distance to the reference point 50 of the photosensitive body 4. At this time, the slit part 6 is moved around the center 41 of rotation of the photosensitive body 4 or in the tangential plane direction of the reference point 40 in synchronism with the scanning of the mirror 5 to adjust luminous flux passing through the slit opening 61. Consequently, the distortion of the projection image formed on the photosensitive body is minimized.

Title: Method for production of optical waveguide
Inventor: OTOMO KATSUYA
IPC: G03F7/20
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing an optical waveguide which is capable of exactly aligning even a substrate having warpage and slight foreign matter to a wafer chuck of an exposure device. SOLUTION: This process for producing the optical waveguide consists in bringing only the one point of the substrate 1 on the side abutting on bearings 21 into contact with the wafer chuck 19, floating the opposite side and sliding the floated side of the substrate 1 in a slope part 28 of a jig 26 when setting the substrate 1 to the wafer chuck 19 of the exposure device, by which the substrate may be pressed to the plural bearings 21 without allowing the rear surface of the substrate 1 to come into contact with the wafer chuck 19. Consequently, even the substrate having the warpage or the substrate having the slight foreign matter 31 on the rear surface may be surely mated with the plural bearings 21 without being hooked to the wafer chuck 19 and the substrate 1 may be aligned and set at the center 22 of the wafer chuck 19.

Title: Circulator for bath water
Inventor: KITA SHIGEHIRO
IPC: A61H23/00
Filed: 1989-10-06
Abstract: PURPOSE:To prevent decrease in an amount of water circulated with a passage of a jet nozzle when a bath water is heated by removing a detachable jetting section from the side wall of a bath tub when the bath water is boiled up and mounting it for massaging. CONSTITUTION:After a bath tub 1 is filled with water, with a jetting section 3 of a detachable jet nozzle not on a fixed section 2, a circulation pump 6 is driven to such the bath water with a hydrocircuit 4 and returned to a both tub through a jet nozzle fixed section from the hydrocircuit 5 via a heat exchanger 7. Thus, while the bath water is circulating, a burner 8 is combusted to heat the heat exchanger and when the bath water is boiled up, the jetting section is removed. In this manner, the circulation water contains no bubble as it does not pass through the jet nozzle and hence, there is no reduction in the amount of circulating water. In addition, switching over to a jet bubble injection is accomplished easily by mounting the jetting section.

IPC: B65D41/04
Filed: 1993-10-20
Abstract: PURPOSE: To provide an integrated plastic closure which is resistant against loads applied on the top and free of shrink-fitting to the outer side surface of a mouth edge of a container. CONSTITUTION: A sealing ring 24 extending inwardly downward from a closure body is provided. When a closure is tightened, the sealing ring 24 is supported from its back side by a stepless connection and counteraction surface 34 of the closure body, and covers the circumference of the outside diameter of a bottle neck and a whole annular flat surface.

However, when the pressure in the product becomes high, effective sealing is formed between an outer side surface of the bottle and the sealing ring.  In this way, the connection an counteraction surface 34 is rough-finished, and the pressure of the product is applied to the back side of the sealing ring.

IPC: C25D11/04
Filed: 1990-10-02
Abstract: PURPOSE:To shorten machining time and a manufacturing process by forming a delicate Al2O3 membrane at the sliding face of one seal ring, and jointing a porous ceramic sliding member to the sliding face side of the other seal ring. CONSTITUTION:The sliding face of an Al alloy made seal ring 21 is ground to make wavy deformation small, and then a delicate Al2O3 membrane is formed at the machined face. This Al2O3 membrane 24 is formed by electrochemical growth so as to have constant membrane thickness. Also, Si3N4 combined SiC is suitable for porous ceramics used for the sliding member 22 of the seal ring 21 of joint structure. Since this ceramics hardly has measure change at the time of sintering, the deformation of the sliding member 22 is small. Accordingly, the waviness of the sliding face of the seal ring 21 of joint structure with this ceramics jointed to the sliding part is also small. This results in shortening machining time for reducing the waviness of the sliding face and thereby a manufacturing process.
