Title: Position detector for liquid pressure cylinder
Inventor: YUASA YASUHIRO
IPC: G01B7/00
Filed: 1990-08-18
Abstract: PURPOSE:To obtain the position of this cylinder continuously with high resolution by varying the magnetic resistance of a coil part on the side of a cylinder main body continuously through one cycle and detecting the position of a rod continuously within a range of one cycle correspondingly. CONSTITUTION:Primary coils A1 - D1 and secondary coils A2 - D2 are provided individually for respective groups A - D. A magnetic circuit varies in reactance among respective phases A - D according to th linear displacement of a magnetic ring rod 2 and deviates by 90 deg., phase by phase. The primary coils of the phases A and C excited in mutually opposite-phase relation with a sine wave signal sinomegat and the outputs of secondary coils A2 and C2 are added in in-phase relation. The phases B and D are the same. When the output signal Y of a detection part 20 is Ksin(omegat+phi) and K is a constant, a phase shift phicorresponding to a reference signal sinomegat is measured to detect the position of the rod 21. The absolute linear position within a range of a distance P can be detected with the electric phase shift value phi of the signal Y.

Title: Device for fitting spiral tube
Inventor: ISHIDA TAKASHI
IPC: F16L57/00
Filed: 1990-08-17
Abstract: PURPOSE:To fit a spiral tube to a material to be fitted easily, securely and quickly, by driving a rotary driving member to rotate a spiral tube in the reverse direction for enlarging a diameter thereof, and inserting a material to be fitted. CONSTITUTION:A spiral tube 5 is inserted into a semicircle pipe 4 for location, and one end thereof is hooked on a shaft 2 of a motor 1, and the other end is hooked on a supporting part 3 of the semicircle pipe 4. The spiral tube 5 is thereby fitted to be supported. Next, a switch of the motor 1 is turned on to rotate the shaft 2 in the direction reverse to the spiral direction of the spiral tube 5, and a diameter of the spiral tube 5 is therefore enlarged. When the outer periphery of the spiral tube 5 abuts on the inner surface of the semicircle pipe 4, the switch of the motor 1 is turned off, and a rubber hose 6 is inserted into the semicircle pipe 4. After the insertion, when both ends of the spiral tube 5 are removed, the spiral tube 5 is rotated by the restoring force from the diameter-enlarged condition to be fitted to the outer periphery of the rubber hose 6.

Title: Grooving tool
Inventor: ARAI TATSUO
IPC: B23B27/16
Filed: 1994-09-12
Abstract: PURPOSE: To reduce the pressing force required to insert a throw away tip and reduce the labor and time in tip replacement and the like by forming a relief part partitioning a clearance to a guide part in the mounted state of the tip. CONSTITUTION: When the tip of a guide part 27 goes over the intersection part of the pressed part 36 and relief part 35 of a tip 23, a clearance C is partitioned between the guide part 27 and the relief part 25, so that there is no force acting on the tip 23 from the guide part 27. As a result, the force required for tip insertion is reduced from the maximum value. With the tip 23 further pushed in by this reduced force, the pressing part 28 of a clamping part 25 adheres closely to the pressed part 36 of the tip 23, so that the tip 23 is fixed being pressed onto the seat part 24 side of a tip fitting seat. The tip 23 can thereby be inserted and fixed with small force.

Title: Method and device for changing coefficient in complex adaptive equalizer
Inventor: UU ETSUCHI PAIKU
IPC: H04L25/03
Filed: 1992-07-27
Abstract: PURPOSE: To reduce a convergence time by updating in parallel each product with preceding data as to N-set of coefficients, to bring about complex coefficients whose N-set of coefficients are updated for selective input to an equalizer filter. CONSTITUTION: A multiplier means may be made up of a plurality of programmable logic array(PLA) multiplier stages, corresponding to a plurality of delay stages in a delay section 94. Each delay stage and PLA multiplier stage corresponds to an accumulator and to any of gain adjustment stages 102a-102n to provide a parallel processing path. Each parallel processing path 120 causes a distributed VLSI slice in the manufacture of an integrated circuit. Since a coefficient update calculation circuit updates all N-set of coefficients, in parallel for each filter clock cycle in place of updating one coefficient for one cycle, then no detrimental adverse effect is received on a convergence time of an equalizer, due to the actual execution of the LMS algorithm.

IPC: B29C35/02
Filed: 1990-08-20
Abstract: PURPOSE:To obtain a vulcanized rubber body, the surface state of which is favorable, by a method wherein excess rubber material due to thermal expansion is escaped from the central part of a green rubber material through tubes outside a mold at the vulcanization of the green rubber under pressure in the mold. CONSTITUTION:A lower flange 4, a green rubber material 2' and an upper flange 3 are inserted so as to be laminatingly arranged in the order named in an internal space, which is formed by the bottom plate part 6 and the cylindrical part 7 of a mold. Tubes 12 and 12 are embedded in the green rubber material 12' by being inserted in mounting holes 13 and 13, which are bored on the upper flange 3 so as to arrange the lower end parts of the tubes at the central part of the green rubber material 2'. After that, when the green rubber material 2' under pressure is vulcanized, the green rubber material 2' expands thermally. Excess rubber material 10 due to the thermal expansion escapes from the central part of the green rubber material 2' through the tubes 12 and 12. Accordingly, no flow of rubber under vulcanization occurs at the surface of the green rubber material 2', resulting in making the development on the surface of a vulcanized body difficult.

Title: Radial piston pump
Inventor: YAMAMURA MAKOTO
IPC: F04B1/053
Filed: 1989-08-25
Abstract: PURPOSE:To prevent the phenomenon of back flow from a cylinder to a cam chamber and obtain stable flow rate characteristics by making a cylinder continuous to another cylinder in an expansion stroke immediately before a piston reaches upper dead center, and interrupting the continuity immediately after the piston is reversed from the upper dead center. CONSTITUTION:When a piston 6 of (a) reaches the vicinity of upper dead center at the end of a contraction stroke, a hole part 16 is overlapped with an annular groove 15. As a result, a cylinder 5 becomes continuous to the cylinder 5 of (b) adjacent to the opposite side of the rotational direction of a cam 3 via a passage 11. The cylinder 5 of (b) is already in the process of an expansion stroke and has low pressure. Due to the aforesaid cylinder continuity, a part of hydraulic fluid in the cylinder 5 of (a) near upper dead center flows to the cylinder of the adjacent (b), thereby causing a drop in the pressure of the cylinder 5 near upper dead center. When the cylinder 5 of (a) enters an expansion stroke and the piston 6 thereof comes slightly lower than upper dead center, continuity between the hole part 16 and the annular groove 15 is broken and normal intake operation is thereafter until the piston 6 reaches the lower dead center thereof.
