Title: External joint member for constant-speed universal ball joint
Inventor: PEETAA URUBAN
IPC: B21J5/12
Filed: 1995-03-13
Abstract: PURPOSE: To extend a ball track center line in non-parallel to the axis of an outer joint member by limiting and contracting an axial center part of a tubular member in cross section more than a tip area and forming a flange on an axial one tip side of the tubular member. CONSTITUTION: This outer joint member has a ball track 22 which is manufactured from a tubular member 1 as a formed planar metal member and receives a torque transmission ball. An axial center part 8 of the tubular member 1 is limited and contracted in cross section more than axial tip areas 6, 9, 7, 10 and a flange 6 extending in the radial direction is formed on an axial one tip side of the tubular member 1. Further, the center line of the ball track 22 is extended in non-parallel to the axis of an outer joint member 11. Therefore, a material of the ball track area is strengthened and at the same time, the ball track 22 is deformed and the extending of the ball track 22 in the strengthened flange area is ensured.  Because the ball track 22 is not extend up to the other tip part side of the tubular body having no flange area, a crack from the axial tip of the tubular body can be prevented.

Simultaneously with release of the smell component adsorbed to the deodorizing catalyst covering layer 30a, oxidative decomposition of the smell component is effected through catalysis of a catalyst material to bring the smell component into an odorless state. This constitution produces a stable deodorizing effect.

Title: Optical modulating device
Inventor: BABA TAKESHI
IPC: H04B10/54
Filed: 1983-05-06
Abstract: PURPOSE:To obtain an optical modulating device which is capable of obtaining a signal light having a good S/N ratio by irradiating by a luminous flux the foams which have reached a position where a light scattered by other than the foams is not generated even if the luminous flux is irradiated. CONSTITUTION:A liquid layer 2 of an optical modulating element is illuminated by selecting various conditions such as an illuminating position where a pattern of a heating resistor is not illuminated by an illuminating luminous flux 22, and a luminous flux incident angle, etc. Accordingly, vapor foams generated in the vicinity of the surface of heating resistors 6a, 6b rise in the vertically upper direction by a buoyancy, and when they reach a height (h), the illuminating luminous flux 22 is scattered. The luminous flux which has not been scattered by the vapor foams passes through a cylindrical lens 23, and thereafter, is shielded by a light shielding plate 24, but a luminous flux 26 scattered by the vapor foams passes through the cylindrical lens 23, and thereafter, its one part is shielded by the light shielding plate 24, and the greater part of the scattered luminous flux advances without being shielded by the light shielding plate 24. In this way, a signal light whose intensity has been modulated is obtained. In this way, the illuminating luminous flux is not scattered by the heating resistor patter, etc., therefore, it becomes a signal light having an excellent S/N ratio and can be extracted.

Title: Device for inverting and discharging recording paper sheet
Inventor: KOBAYASHI HIROYUKI
IPC: B65H29/52
Filed: 1985-04-16
Abstract: PURPOSE:To aim at preventing a paper jam during invert discharge of paper sheets and at also preventing an ink paper sheet from being wasted during normal discharge of the paper sheets, by setting the peripheral speed of an inverting and discharging roller to be higher than that of a paper discharge roller in accordance with the length of an added inverting path so that the discharging time of the paper sheet upon normal discharge is made to be equal to that upon invert discharge. CONSTITUTION:In order to perform the invert discharge of a recording paper sheet, an inverting and discharging device 20 is mounted on the paper discharge section of a thermal printer instead of a guide unit, and therefore, the recording paper is fed onto an inverting path B after passing through a discharging path A. In this arrangement the conveying force of an inverting and discharging roller 24 for the recording paper sheet is set such that it is greater than that of a paper discharge roller 15 but is less than the carriage force of a platen roller 9 so that the recording paper sheet is discharged by means of the roller 24 when the trailing end of the recording paper sheet has passed through between a thermal head 6 and the roller 9 after the leading end of the recording paper sheet reaches the roller 24. Thus, the time for invert discharge is made equal to that for the normal discharge, thereby, it is possible to prevent a paper jam due to a lack of the time for the invert discharge in the device 20, and to prevent an ink sheet from being wasted due to excessive a normal discharge time.

Abstract: PURPOSE:To obtain a highly rigid sliding material that features a excellent slidableness and a good toughness by blending a synthetic resin with 6 potassium titanate whiskers made from a natural rutile sand and given by the formula K2(Ti, M)6. O13. CONSTITUTION:6 potassium titanate whiskers made from a natural rutile sand is descrived by the following formula: K2(Ti, M)6.O13. Unavoidable impue elements such as Mg, Ni, Cu, Zn, Al, Fe, Cr, Ga, Si, Nb, Zr, V, Mn, P, S, etc. (indicated by M in the formula) originated in impurity of the national rutile sand are taken in molecules of a material to improve its toughness.
