Title: Shift fork shaft
Inventor: ODAKAWA NOBUYUKI
IPC: F16H63/32
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To reduce work processes and provide a shift fork shaft of high reliability by forming a shift yoke of sheet metal by pressing, and plastically deforming both ends of a fixture to fix a shaft fitting part with a slit of a yoke revealed, to a shift shaft. SOLUTION: A shift yoke 56 is formed of sheet metal by pressing, and a shaft fitting part at the other end is mounted on an intermediate part of a shaft part by a winding-fastening system so as to reveal a slit 60. At the time of fixing the shaft fitting part 58 to the shaft part 52, a spring pin 54 is inserted through a first hole part 64 on the shaft 52 side and a second hole part 66 on the shift yoke 56 side, and both ends are caulked to fix the shaft fitting part 58 to the shaft part 52. With the shift yoke 56 thus formed of sheet metal by pressing, work hardening is generated during press working so as to dispense with a hardening process after press working, and only machining of drilling the second hole part 66 on the shift yoke 56 side has to be performed so as to reduce work processes.

Title: Insulating type semiconductor device and molding tool thereof
Inventor: HAGIWARA YOSHIMI
IPC: H01L23/31
Filed: 1986-02-19
Abstract: PURPOSE:To improve packaging reliability, by increasing the thickness of a screw inserting hole part and a package part covering a chip, and partially decreasing the thickness of the package at the main surface of a header on the side of the screw inserting hole just like the package at the back surface of the header. CONSTITUTION:Leads 2 are protruded from a package 1. The other end part of the package 1 or the opposite side of said protruded part is made partially low by one step along the direction of the width. At the low part 3, resin is positively injected in the lower surface of a header when the resin is molded. Holes 4 are provided at the back surface of the low part 3 when the resin is molded. The holes 4 are filled with a hardened filler 5. A screw inserting hole 7 is provided at a part close to the low part 3 in the package. The hole 7 is used when an insulating type semiconductor device 6 is attached to an attaching plate. The resin at the package part is as thick as several mm. Therefore, even if a screw is inserted in the screw inserting hole and tightened with a large force when a power transistor is packaged, the resin part is not crushed with the tightening force. Cracks are not yielded and the resin is not peeled off. Thus the packaging reliability is enhanced.

Title: Flame-retardant finishing agent
Inventor: OGAWA YOSHIKATSU
IPC: C09K21/12
Filed: 1982-03-04
Abstract: PURPOSE:To provide a flame-retardant finishing agent consisting mainly of acidic phosphate of dibromoneopentyl glycol and imparting excellent flame retardance, drape and hand and resistance to light. CONSTITUTION:The flame-retardant finishing agent consists mainly of acidic phosphate of dibromoneopentyl glycol obtained by interaction of dibromoneopentyl glycol and phosphoric anhydride in the molar ratio of 3:0.5-4. When phosphoric anhydride is used in less than 0.5mol, the amount of unreacted dibromoneopentyl glycol increases leading to lowering of flame retarding effect and drape and hand. When it is used in more than 4mol, the amount of unreacted phosphoric anhydride increases leading to insufficient drape and hand since phosphoric acid is formed by the addition of water and the resultant flame retarder has poor compatibility with synthetic resin emulsion. The agent is suitable for flame-retardant finishing of fibers, textile goods, urethane foam, cellular plastics, etc.

Title: Mass spectrograph
Inventor: MATSUDA HISASHI
IPC: H01J49/28
Filed: 1983-03-01
Abstract: PURPOSE:To obtain a highly efficient mass spectrograph for focusing an ionic current which has passed through a deflecting magnetic field by use of a cylindrical electrode, which can be easily made, by installing electrostatic tetrode lenses between the slit of an ion source and the deflecting magnetic field. CONSTITUTION:An ion source 1 consists of an ionization chamber 2 and a plural number of accelerating electrodes 3. An ionic current accelerated is discharged from an ion source slit 4. The ionic current, after passing through electrostatic tetrode lenses 5 and 6, becomes incident upon a deflecting magnetic field 7 and deflected. Among the thus deflected ions, those passing through a detection slit 8 are catched by an ion detector 9. The intensity of the deflecting magnetic field 7 can be externally varied. The position of the detection slit 8 is fixed. The ionic current is accelerated in such a manner that the kinetic energy of ions becoming incident upon the deflecting magnetic field 7 is constant. The ions becoming incident upon the magnetic filed 7 are deflected by different angles according to the mass of each ions since its momentum differs according to its mass. Therefore, ions with a different mass are catched by the ion detector 9 when the intensity of the magnetic field 7 is changed, thereby enabling mass analysis of ions to be carried out.

In reception mode, section marks RS are printed and in local mode, section marks LS are printed by three each. Thus, a copy having clear sections of a telegraphic message is taken with the simple constitution.

Title: Vibro-isolating device for engine
Inventor: WADA YUTAKA
IPC: F16F15/08
Filed: 1983-02-28
Abstract: PURPOSE:To make a spring constant suited to running conditions, etc., selectable at will and aim at improvements in a vibro-isolating effect as well as the promotion of longer service life, by making up a tilt angle in vibro-isolating rubber alterable. CONSTITUTION:With turning force added to a plate 10 at the lower side by a motor 14 via a piston 15 and a segment gear 13, a vibro-isolating device 4 is turned round clockwise and counterclockwise each centering on pin 7 along a rail 12 and able to optionally select a tilt angle theta. When this tilt angle is made to be smaller, vibro-isolating rubber 3 comes to deformation in a compression direction,becoming high in a spring constant, and when the tilt angle theta is made to be larger, the vibro-isolating rubber 3 comes to deformation in a shearing direction, causing the spring constant to be reduced. Therefore, in time of idling and so on, the spring constant of the vibro-isolating rubber is made to be brought down, raising up the vibro-isolating effect, and simultaneously in time of running on a rough road, the spring constant is made to be larger and its displacement is reduced to some extent, thus longer service life is well promoted.
