IPC: G02B6/46
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To provide the traction terminal structure of an optical fiber cable which can excellently be towed in a conduit. SOLUTION: This traction terminal structure is constituted by compressing and connecting a compression sleeve 6 of a compression sleeve 5 with a traction ring to a tensile-strength body 4 exposed by removing the clad layer 2 and flexible rod type body 3 at a terminal of the optical fiber cable 1 composed of the flexible rod type body 3 which contains a coated optical fiber, the clad layer 2 covered with the flexible rod type body 3, and the tensile-strength body 4 for reinforcement compounded with the center part of the flexible rod type body 3.  In this case, the clad layer 2 and flexible rod type body 3 at the terminal of the optical fiber cable 1 are removed stepwise to expose the flexible rod type body 3 and tensile-strength body 4 to a specific length, and the compression sleeve 6 of the compression sleeve 5 with the traction ring is fitted to an engagement member 7, which is engaged and gripped by the flexible rod type body 3.

Title: Preparation of semiconductor device
Inventor: KITAHIRO ISAMU
IPC: H01L21/52
Filed: 1979-09-19
Abstract: PURPOSE:To readily form a gold foil and obtain an excellent ohmic contact by selectively coating the surfaces of an Au foil with a material to be a donor or acceptor for a semiconductor, and mounting a semiconductor pellet by using the Au foil. CONSTITUTION:Both surfaces of an Au foil 1 are provided with Al 2 insularly, and treated on heating to obtain Au-Al alloy 2'. Then a package 3 on which the Au foil 1 has been placed is heated to at approximately 400 deg.C, and a semiconductor pellet 4 is placed on the foil 1. Rubbing them each other causes the exposed Au of the Au foil surface to react with the Si in the pellet 4 to provide an Au-Si eutectic alloy. The reaction rapidly proceeds, and the Al dissolves into the Au-Si eutectic alloy. On cooling, the excess Si recrystallizes on the lower surface of the pellet 4, containing the Al. Because the segregation coefficient of Al is approximately 100 times larger than Au, providing the surfaces of the Au foil with Al with its amount previously calculated permits a sufficiently excellent ohmic contact to be obtained.

IPC: F16D11/04
Filed: 1979-09-19
Abstract: PURPOSE: To enable intermittent on-off operation of a clustch constructed with engaging clutch claws having a slope alongside one side of plate cam, by selecting  shape of the plate cam suitably.  
     CONSTITUTION: When a lever 24 is pulled in a direction of an arrow by suitable method to release its engagement with a stage 25 of a plate cam 19, the plate cam is allowed to turn and clutch claws 17, 17' tightly engage, and then a holder 8 is free from pressure against a leaf spring 13. A steel ball 9 within a holding hole 10 of the holder 8 gives stong pressure against a tapered inner wall 7 of an outer ring 3 rotated by a motor 5 and against a notched face 14 on an outer circumference of  an inner ring 12 to transmit rotation torque of the outer ring 3 to the inner ring 12  and a main shaft 1. When the lever 24 comes in an engagement with the state 25, a  sloped face 18' of the clutch 17' rides over a sloped surface 18 of the clutch claw 17  to release the steel ball 9 from the tapered inner wall 7 and to cause the main shaft  1 to stop.

Title: Data protecting system for direct access memory
Inventor: HONDA ISAO
IPC: G06F12/00
Filed: 1983-07-06
Abstract: PURPOSE:To protect the central information stored in a memory and important for operation from destruction for a direct access memory, by setting two types of modes, i.e., the normal and special right modes, in terms of a program. CONSTITUTION:When an access is given to a direct access memory DASD3, a normal mode and a special right mode are set in terms of a program. In a normal state the special right mode is used for the program which is offered to a user from a maker, and the normal mode is used with a user program. The special right mode is available only with a privileged user, and only a privileged user can give a write access to the memory DASD3. Therefore an access is possible to an area designated by a table of a magnetic disk controller DKC2 in any special right mode. While an access is possible with a writing system only in the special right mode. Thus the central information which is important for operation can be protected from destruction.
