Title: Optical coupling parts
Inventor: TOUJIYOU MASAAKI
IPC: G02B6/28
Filed: 1983-09-29
Abstract: PURPOSE:To prevent degradation of optical coupling characteristics even if an adhesive is hardened and contracted, by sticking interference film filters, which reflect two lights difference in wavelength, to a face orthogonal to the optical axis of a rod lens and a face inclined to this face. CONSTITUTION:The light having a wavelength lambda1 from an optical fiber 11 passes an optical path 17 and is reflected on an interference film filter 15 orthogonal to the optical axis of a rod lens 4 and passes an optical path 18 and is coupled to a fiber 13. The light having a wavelength lambda2 from the fiber 11 passes the filter 15 and a prism 20 and is reflected on an interference film filter 16 inclined to the optical axis of the rod lens and is coupled to a fiber 12. The filter 16 is stuck at an angle to the filter 15, and the inclination deviation preventing prism 20 is inserted and adhered in the wedge-shaped part between them, and intervals between filters 15 and 16 and the prism 20 are approximately uniform; and therefore, variance of inclination of the filter 16 is prevented even if the adhesive is hardened and contracted, and degradation of optical coupling characteristics is prevented.

Abstract: PURPOSE:To simplify the decomposition and removal by providing a rib and a stopper with a holder integrally so that the rotary fulcrum of a lever and the lever are driven normally so as to eliminate the need for a special jig, thereby mounting the lever to the holder. CONSTITUTION:Both ends of a torsional coil spring 16 are spread in directions of arrows E, F and the inner diameter of the coil part 16a is increased more than the outer diameter of a falling off preventing rib 22 and fitted to a boss 21. In penetrating a pin 14 through the throughhole 23 of the holder 26, the angle between a notch 18 and the falling off preventing rib 22 is made coincident to fit the throughhole 17 of the lever 15 to the boss 21 and both ends of the torsional coil spring 16 are locked respectively to a locking part 19 and a locking rib 20, then the lever 15 is turned freely around the boss 25 and energized clockwise. Thus, the tip of the lever 15 is not floated upward by a retaining rib 24, the outer circumferences of the throughhole 17 and the notch 18 are clipped to the holder 26 and the escape preventing rib 22 and the lever 15 is not fallen off from the holder 26. The procedure for the decomposition/ removal is applied reversely to the loading procedure.

Filed: 1988-07-20
Abstract: PURPOSE:To obtain a uniform shape accuracy by forming a tapered surface along with the inner periphery of a bottom part inside the blank, forming tapered surfaces on the parts of the punch to be inserted respectively and abutting formed taper faces respectively. CONSTITUTION:The blank 22 is put externally on the punch 36 fixed on the upper face of the 1st die 32. At the time when the front end of the punch 36 is abutted to the bottom part of the blank 22, the taper faces 50 formed on the side face parts 46 of a square pillar 40 are abutted on the surrounding taper face 24 formed on the inner periphery in the bottom face of the blank 22. Because these taper faces 50 are formed on the symmetrical positions for the center of the punch 36, these taper face 24 and taper faces 50 are closely contacted mutually, the blank 22 is positioned accurately for the punch 36. By this method, in the next stage of ironing, the outside peripheral surface of the blank 22 is ironed by the die, the prior conditions for accurately forming the inner peripheral surface of the blank 22 are arranged.

CONSTITUTION:A cylinder 3 filled with compressed air is received in a receiving part 4 and a bottle 6a is moved to the left by revolving a knob 6c to engage the jet orifice 3a of the cylinder 3 with a connector part 5 in an inserted state. Whereupon, a closure plug 7 is pressed by a projection 7b and the compressed air in the cylinder 3 is emitted to flow in a pressure reducing control mechanism 10 through an emitting orifice 5d and a pipe 9. Further, the air whose pressure is reduced to predetermined one by the pressure reducing control mechanism 10 flows in an opening and closing mechanism 13 through a pipe 11. When the opening and closing mechanism 13 is opened, air of predetermined pressure flows in the hollow part of the housing 2a of a bubbling plate 2 to be injected into a bath as numberless small air bubbles through the small vent holes of an air bubble generating plate 2b. When the cylinder 3 is filled with oxygen enriched air as compressed air, air bubbles due to oxygen enriched air are generated in the bath.

Title: Magnetic recording medium
Inventor: YOKOZAWA HIROKI
IPC: G11B5/72
Filed: 1993-07-23
Abstract: PURPOSE:To enable simultaneous measurement of the film thickness and hydrogen content of a protective film of carbon hydride by measuring a reflection spectrum in an ultraviolet-visible region of the protective film. CONSTITUTION:In regard to the film thickness and hydrogen content of a protective film of carbon hydride, a reflection spectrum in an ultraviolet-visible region is measured by using an ultraviolet-visible spectrophotometry. In the case when the film thickness of the protective film of carbon hydride is such a specific film thickness as showing interference in the ultraviolet-visible region, the maximum absorption in the reflection spectrum of the protective film of carbon hydride is caused by the interference, and the film thickness is determined by measuring the wavelength thereof. As for measurement of the hydrogen content in the protective film, on the other hand, the hydrogen content is varied in a state of the film thickness being fixed and absorbance in the maximum absorption wavelength of each varied content is measured, since the intensity of the interference of the spectrum differs according to the hydrogen content. The hydrogen content can be known from the correlation determined between the hydrogen content and the absorbance.
