Title: Plastic optical fiber and its production
Inventor: NONAKA TAKESHI
IPC: C08F20/22
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To provide a plastic optical fiber having excellent transmission loss in which the core has desired distribution of the refractive index. SOLUTION: In this plastic optical fiber, the refractive index of the core decreases from the center to the outer circumference and the core is composed of plural layers having different refractive indices. The resin which constitutes layers each having different refractive index from others is such a compsn. that contains a different amt. of a polymer produced by polymn. of monomers expressed by general formula CH2 CR<1> COOCR<2> R<3> R<4> from other compsns. In formula, R<1> to R<4> are halogen atoms, deuterium or halogenated alkyl groups. Each resin layer 5 which constitutes the core 1 is prepared by mixing the monomer and a nonpolymerizable org. compd. in the respective mixing ratio to obtain a mixture liquid 10, injecting the liquid 10 in a polymer tube 3 which is to be used as a clad, successively polymerizing the material while rotating the tube to form the layer.  Then the obtd. plastic optical fiber perform is heated and drawn.

Title: Water softening apparatus
Inventor: KAYAHARA TOSHIHIRO
IPC: C02F1/42
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To simplify the control of the whole body of a water softening apparatus, integrate a salt water supplying part, and miniaturize the water softening apparatus by arranging a raw water supplying part and a salt water supplying part in the upper part of a resin cylinder and regenerating the resin in the resin cylinder by passing the salt water from the salt water supplying part downward in the resin cylinder. SOLUTION: In a soft water passing process, raw water in a raw water tank 4 is supplied to a resin cylinder 1 through a raw water line 7 and hard water is softened by an ion exchange resin 3 during a process of passing the raw water as upward flow and the resultant soft water is supplied through a soft water outlet part 14. Then, in salt water generating process, saturated salt water in a salt water tank 5 is led downward through a slat water flowing down line 19 and, on the other hand, the raw water in the raw water tank 4 is led downward through a raw water flowing down line 22 and the salt water and the raw water are mixed at the soft water outlet part 14. The obtained salt water is led downward from the upper part of the resin cylinder 1 to regenerate the ion exchange resin 3.  On completion of regeneration, water washing process is carried out, and the remaining salt in the ion exchange resin 3 is pushed out and washed out by raw water from the raw water flowing down line 22.

Title: Grafting device
Inventor: NANBA IZUMI
IPC: A01G1/06
Filed: 1995-04-13
Abstract: PURPOSE: To check existence of abnormality in each process at several check points by setting the several check points at important parts corresponding to operation processes. CONSTITUTION: This grafting device is equipped with a main driving shaft 1 to which plural cams 2 are attached. Grafting operation is automatically carried out according to a prefixed order through the cams 2 and various actuators 5 by rotation of the main driving shaft 1.

Title: Die for cold forging
Inventor: OGAWA MASUJI
IPC: B21J13/02
Filed: 1982-05-25
Abstract: PURPOSE:To prevent occurrence of cracks in forming members at the time of forging and simplify the constitution of the die, by constituting the forming hole in the die body with plural forming members and, at the same time, by installing a hole through which a knockout pin is inserted, to the lower part of the forming hole. CONSTITUTION:A forming member 12 is fitted to the upper half part 2a of a reception hole 2 in a die body 1 and a forming hole 4 having a nearly hexagonal cross section and a knockout pin inserting hole 6 communicating with a concaved part 7 and the forming hole 4 are formed on the center line of the forming member 12. Moreover, the forming member 12 is equally divided into six parts by three planes containing the central axis of the hole 6 and two angular parts of the forming hole 4 which are opposed to each other, respectively, and each split piece 12a is closely contacted with each other. Since each split piece 12a can be deformed individually against elastic force when a nut is forged by placing a metallic material having a nearly cylindrical shape in the forming hole 4 and by pressing the metallic material with a pressure pin, the breakage of the forming member 12 by the angular part of the forming hole 4 can be prevented.

Title: Enclosed type rotary compressor
Inventor: HIKOBE ATSUO
IPC: F01C21/08
Filed: 1981-06-08
Abstract: PURPOSE:To minimize the leakage of high-pressure coolant gas, by increasing the thickness of a roller constituting a rotary compression element of a compressor at its upper end portion while decreasing the same at its lower end portion, said roller being designed to rotate eccentrically around an eccentric portion of a turning shaft in a cylinder. CONSTITUTION:A roller 8 adapted for compressing a coolant gas is fitted loosely around an eccentric portion 7 of a turning shaft 4. Here, since the thickness of the roller 8 is increased by an annular flange 17 formed at the upper end portion of the roller 8 in the manner of protruding into an annular space 16, flow resistance through a clearance 14 between an upper frame member 12 and the upper end 15 of the roller 8 can be increased without reducing the clearance 14. Therefore, leakage of high-pressure coolant gas from the high-pressure, annular space 16 to a low-pressure section in a cylinder 6, so that the coefficient of performance of a compressor can be increased without increasing the input. At the same time, the total weight of the compressor is reduced by decreasing the thickness of the roller 8 at the portions other than the upper end portion 15 of the roller 8.

Filed: 1989-04-06
Abstract: PURPOSE:To increase speed and make a device to be compact by insulating a gate electrode consisting of a second-layer polycide layer from both diffusion layers and a first-layer polycide layer for forming it in a direction crossing both diffusion layers. CONSTITUTION:Polycide layers 12 and 14 are formed on a substrate 2 being in contact with diffusion layers 8s and 8d. It reduces resistance of bit line and increases speed. Also, since the diffusion layers 8s and 8d of a memory transistor region are formed by diffusing impurities within the polycide layer, a shallow diffusion layer can be formed, thus miniaturizing the memory transistor. Also, since there are the polycide layers 12 and 14 between the diffusion layers 8s and 8d and a metal wire 22 at the memory transistor region, no aluminum spike occurs even in a shallow diffusion layer. Since there are the polycide layers 12 and 14 and oxide films 18 and 20 on the diffusion layer of the memory transistor region, it becomes difficult to allow a core ion to be implanted into the diffusion layers 8s and 8d when implanting the core of mask ROM, thus preventing junction capacity form increasing.
