Title: Spray washer
Inventor: MIYAO KIMIFUMI
IPC: B60S3/00
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To allow an operator to freely switch a washing mode between spray washing and brush washing at need by installing a high pressure discharge port, a low pressure discharge port and a washing brush at the tip and switching the discharge between high pressure discharge and low pressure discharge by the operation of a valve at hand. SOLUTION: A washing gun 2 incorporates a manual valve 21, and has a handle part 23 equipped with a lever 22 for opening and closing the valve 21 at hand, a barrel 24 of a metal pipe, and a nozzle part 25 and a washing brush 26 set at the tip thereof. The barrel 24 has double-pipe structure of two metal pipes of different diameters, and the inner pipe of small diameter forms a high pressure line, and a low pressure line is formed between the outer and the inner pipes. Washing water is normally sent to both the lines, but when the lever 2 is gripped, the low pressure line is shut off to send washing water only to the high pressure line.  Since the forced feed of water and washing water from a washer body 1 are automatically switched according to a prescribed sequence, in agreement with it, an operator operates the valve 21 of the washing gun 2 and can separately execute spray washing and brush washing.

Title: Method for evaluating infrared optical fiber
Inventor: WATARI MASABUMI
IPC: G01M11/00
Filed: 1987-10-26
Abstract: PURPOSE:To clearly detect a defect position of the optical fiber by placing the KRS-5 optical fiber between two deflecting plates, projecting light in the sectional direction of the optical fiber from behind one deflecting plate, and detecting light passing through the deflecting plate. CONSTITUTION:When CO2 laser beam is entered into the KRS-5 optical fiber 2 through a condenser lens 1, the laser beam is absorbed at the defect 6 to generate heat. A deflector 3 and an analyzer 4 are installed having a 90 deg. angle of deflection across the optical fiber 2. The light is projected from one side. The projected light is deflected linearly by the deflector 3 and no transmitted light is obtained through part of the optical fiber 2 which has no crystal strain. The defect part 6 rotates the light deflected by the deflector 3 because of crystal strain due to the heat generation, so the transmitted light of the analyzer 4 is obtained. This strain light is photodetected by a sensor. Consequently, the defect position of the optical fiber 2 is clearly detected.

Title: Diffusing method for impurity
Inventor: MIZUNO BUNJI
IPC: H01L21/265
Filed: 1987-10-26
Abstract: PURPOSE:To diffuse only an impurity at a position selectively opened by a mask material by diffusing the impurity in sold by exposing the solid containing the impurity in a plasma. CONSTITUTION:A CVD oxide film 4, a photoresist 6 are employed as masks on a silicon substrate 2, a desired opening position 8 is formed, and an impurity is, for example, ion implanted thereby to form an impurity layer 10. Only the desired position of thus implanted layer 10 is mask-opened with the photoresist 6 or the like, and exposed with a plasma. Then, the layer 10 of the opening 8 is diffused to form a diffused layer 16. Thus, since the whole substrate 2 does not become a high temperature, the impurity can be diffused only at the position 8 being selectively opened.

IPC: G02B6/12
Filed: 1990-10-08
Abstract: PURPOSE:To realize a connection structure of an optical signal without requiring a complicated optical-path pattern by a method wherein a planar-type optical waveguide is used for an interconnection whose wiring pattern becomes complicated. CONSTITUTION:A wafer 10 is composed of a substrate part 12 and thin layers 14, 16, 18, 20; the layer 12 is composed of GaAs with a thickness of 10mm and confines an incident optical pulse in an optical medium; the optical pulse propagates a length of the layer 14 in all directions. The optical waveguide 14 functions as a jointly owned transmission means to which all subsystems 18A have been connected. A layer 28 is provided with one set of light-emitting elements 26A for output use and one set of photodetectors 28B for input use. Information on an initial optical image is detected by the set of the photodetectors 28B for input use; electric outputs are input to the various subsystems 18A. Electric outputs of the subsystems 18A are used as inputs to light sources in the layer 16. The light sources supply optical pulses to the layer 14 as a jointly owned waveguide. The optical pulses are detected by reversal photodetectors connected to the subsystems 18A. After a processing operation of these, the subsystems 18A turn on the prescribed light sources 28A on their surface. Thereby, a picture element pattern after the processing operation can be formed on the surface.

IPC: H04L12/00
Filed: 1992-10-08
Abstract: PURPOSE:To reduce the intra-network traffic at the time of initialization by transferring intra-network messages correspondingly to transmission lines be tween exchanges. CONSTITUTION:The exchange where terminals are stored gives a UNI number to each group to be subjected to the same initialization to manage terminals and manages a connection port (NNI) number and the UNI number peculiar to the last communication destination terminal by a table at each time of call setting of a terminal, and a repeating station manages the UNI number of the transmission source terminal and that of the communication destination terminal by a table with respect to each NNI. The UNI number of the UNI where initializing procedures are started is included in an initializing message and an initialization confirmation message, and the exchange and the repeating station successively transmit the initializing message including the UNI number to the connected NNI corresponding to the UNI in the management table when receiving the initializing message. When all initialization confirmation messages of the NNI on the transmission side are received, the initialization confirmation message is transmitted to the NNI or the terminal on the original reception side, and management tables are cleared.

Title: Preventive curtain against diffusion of polluted water and preventive device against diffusion of polluted water by use thereof
Inventor: SUGIMOTO NOBORU
IPC: E02B15/00
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To improve the function, by providing braid cords in which the end of fiber is continuously fixed along the longitudinal direction, on a support rod and weaving them to form a curtain. SOLUTION: One end or both ends of fiber are continuously fixed to a support rod along the longitudinal direction to form braid cords. A thin plate or a string made of a synthetic resin, a fiber reinforced plastic, a natural fiber, etc., is used for the support body. And the synthetic resin, natural fiber, etc., are used as the fiber fixed to the support body. The braid cords are woven as the warp threads 3 and/or the weft 4 and the crossings 5 are fixed and bound to form a preventive curtain like a fishing net against diffusion of polluted water. On using it, the preventive curtain is hung under floats and sinkers are attached to the lower side.  In this way, since water can pass and mutual fibers are not entangled, the fibers can effectively catch particles in the polluted water and the polluted particles stuck on the fibers can be separated and coagulated and further settled by the movement of mutual fibers resulting from strong and weak water streams.

IPC: A01K87/00
Filed: 1987-10-27
Abstract: PURPOSE:To reduce the number of spiral projections produced in thermosetting thereby to simplify polishing process and improve strength, by tightly adhering and winding a fastening tape around an outer peripheral surface of a prepreg which is obtained by winding a core metal without the edge portions of the tape being overlapped, and winding further the tape with the side edge portions overlapped, then thermosetting, removing the core metal and polishing. CONSTITUTION:A woven fabric of reinforced fibers such as carbon fibers, glass fibers, etc., or a sheet of double fibers is soaked in with a thermosetting resin, for example, epoxy resin, etc., to be a prepreg 1. The prepreg 1 is then wound around a core metal 2. A fastening tape 3 such as a cellophane tape or the like having an appropriate width is spirally wound around the outer peripheral portion of the prepreg 1 in a manner that the side edges of the tape 3 are not overlapped with each other. Thereafter, the tape 3 is further wound in a spiral manner, with the side edges thereof being overlapped. Then, the prepreg 1 is processed through thermosetting, and the core metal is removed. The tape is peeled off. Thus, many small projections 5 are formed on the surface of the thermoset material 1 of a fishing rod. By polishing the thermoset material 1 to remove the projections, a fishing rod is obtained.
