Title: Optical fiber
Inventor: SATO AKIRA
IPC: C03C13/04
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To obtain enough light quantity with a small cross section area of a fiber by using a specified perfluoropolyether or specified low mol.wt. ethylene chloride to form a coating layer having lower refractive index than that of a clad layer. SOLUTION: This optical fiber has a coating layer around an optical fiber comprising a core layer and a clad layer and has a coating layer on the outside. The coating layer has lower refractive index than that of the clad layer and consists of perfluoropolyether expressed by formula I: F-(C2 F4 -CF-O)n -C2 F5 , perfluoropolyether expressed by formula II or low mol.wt. ethylene chloride expressed by formula III. In formulae I-III, m and n are integers >1. When structural mismatch is produced on the interface between the core layer and the clad layer, the light leaking into the clad layer outgoes from the optical fiber. However, because the coating layer formed around the clad layer has lower refractive index than that of the clad layer, the light is reflected on the interface between the clad layer and the coating layer and the light is enclosed in the core layer and the clad layer.  Thus, light is transmitted through the fiber by multiple inner reflection.

Filed: 1987-08-10
Abstract: PURPOSE:To attain operation with a high line recording density and a high track density by specifying the track width of a head, the thickness of a magneto-resistance effect film, and the depth of the signal detecting part of said film. CONSTITUTION:In case the track width is 1-10mum, the thickness of the magneto-resistance effect film is made 50-250Angstrom , and corresponding to these, the depth of the signal detecting part of said film is made 8mum or below. This means that the influence of reverse magnetic field on a thin magneto-resistance effect film can be made small even for a narrow track width, hence the reproduction sensitivity can be upgraded. As a result, a signal can be reproduced efficiently, the recording density can be improved, and a magnetic disk device can be miniaturized and its capacity can be made larger.

Abstract: PURPOSE:To produce an aromatic sec-amino compound important as a raw material for rubber chemical, dye, etc., under a mild condition in high yield. CONSTITUTION:An N-cyclohexylideneamino compound of formula I (R is H, alkyl, alkoxy, NH2, OF or F; n is 0-5; R' is alkyl, phenyl, benzyl, naphthyl, furyl, furfuryl or cyclohexyl) is dehydrogenated in the presence of a hydrogen transfer catalyst (preferably palladium-carrier catalyst) and a hydrogen acceptor, preferably an olefin or a nitro compound by using a polar solvent not containing sulfur such as N,N-dimethylacetamide or p-cresol and/or a co-catalyst such as an alkali (alkaline earth) metal to give an aromatic sec-amino compound of formula II.

Title: Guide structure for press-fit part having o-ring
Inventor: ONISHI YOJI
IPC: F02F1/16
Filed: 1987-08-10
Abstract: PURPOSE:To prevent rise in oil pressure at the time of press fitting even when a shaft surface is coated with a large amount of lubricating oil by setting the maximum value of the gap volume of a guide part to be not larger than a value obtained by subtracting the volume of an O-ring from the whole volume of an O-ring groove. CONSTITUTION:The maximum value of the gap volume of a guide part which is sealed by an O-ring 16, i.e., a sealed volume V formed by a fitting gap in between the guide part of a cylinder liner 14 and a hole 13 is set to be not larger than a value obtained by subtracting the volume V2 of the O-ring 16 from the whole volume V1 of an O-ring groove 17. Thereby, at the time of press fitting the liner 14 with its surface being coated with a dragging preventing lubricating oil, even if the surface is coated with a large amount of lubricating oil, a space equal to or more than the maximum value of an oil quantity which is caught in the gap volume remains in the groove 17. Hence, at the time of press fitting the liner 14, rise in oil pressure within a closed gap which is sealed by the O-ring 16 including the groove 17 can be prevented, preventing the tendency for a part of the O-ring 16 to be floated up from the groove 17.
