Title: Data transfer device
Inventor: ABE SHIGEHARU
IPC: G06F13/28
Filed: 1987-05-29
Abstract: PURPOSE:To enable block transfer by specifying transfer receiver areas as areas to which data are transferred actually and areas to which data are not transferred. CONSTITUTION:The contents of a data transfer receiver start address register SSR1 are outputted to an address bus through an address generator 7 and a sequencer 10 generates a memory read timing signal into a system to read data in a bit computing element 9. Then the contents of a data transfer sender start address register DSR2 are outputted to the address bus through the address generator 7 and the sequencer 10 sends the memory write timing signal into the system, so that the bit computing element 9 writes data. Then the SSR1 and DSR2 are updated so as to indicate next pointers. At this time, the number of transfer bits is subtracted from the value of a data transfer receiver transfer area length register SLR5 to decide whether or not a transfer area specifying device 6 indicates a block transfer area. When the block transfer area is finished, the SSR1 is updated to the value obtained by adding the value of a transfer receiver nontransfer area length register SUR4.

Title: Magnetic head and its production
Inventor: KAMINAKA NOBUMASA
IPC: G11B5/31
Filed: 1987-05-29
Abstract: PURPOSE:To enhance the efficiency of a core and to prevent the degradation in magnetic characteristics by adopting the constitution in which a track width is defined by butting of magnetic metallic films to prevent exposing of glass parts to a surface for sliding with a head. CONSTITUTION:A nonmagnetic film 4 consisting of SiO2, etc., or the same material as the material of a nonmagnetic material 3 consisting of ceramics is formed on the nonmagnetic material 3. The magnetic metallic film 6 consisting of amorphous CoNb or 'SENDUST(R)' material or the like is then formed in the form of multi-layered structure with the nonmagnetic film on said film. Two sheets of the nonmagnetic materials 3 exposed with the films 4 by flattening the surface are thereafter disposed to face each other via a magnetic metallic film 8 consisting of an amorphous CoNb or 'SENDUST(R)' material, etc., to constitute a main magnetic circuit and are adhered to each other. Such bodies are then cut and are butted to each other via a spacer to form the head gap. The efficiency of the core in a high-frequency region is thereby improved, by which the high wear resistance is obtd. and the degradation in the magnetic characteristics is obviated.

Abstract: PURPOSE: To perform fully automatic welding continuously by determining the swiveling center of a welding torch by detecting the circumferential surface of a pipe corssed with a base metal, and controlling the height of the welding torch in such a way that the projecting length of a wire from the torch is made constant thereby forcing the torch to copy the joint part.  
     CONSTITUTION: In the case of crossing a pipe 2a with a tubular base metal 1, and welding its joint part 5 of a saddle-like curved shape, the swiveling center of the welding torch of an automatic welding device 6 is detected by moving the X-axis part 4X and Y-axis part 4Y of a manipulator 4 laterally and longitudinally on the circumferential surface of the pipe 2a. Thereupon, the projecting length of a wire from the welding torch is detected with a control device, and a command is emitted to the control device to control the height of the welding torch in such a way that the projecting length of the wire from the welding torch is made constant, whereby the welding torch is forced to copy the joint part 5.

Title: Wheel cylinder with clearance adjustor
Inventor: TANAKA RYUICHI
IPC: F16D65/54
Filed: 1986-06-12
Abstract: PURPOSE:To enable both the stabilization of the clearance adjusting function and the prevention of the excessive adjustment by deciding the friction force of a friction member regardless of the liquid pressure in a liquid pressure chamber and mounting a relief valve to interrupt the clearance adjusting function when a brake is operated by the pressure over the specified value. CONSTITUTION:The friction force against the internal wall of the hole 18b of a friction member 32 can be obtained over the specified value by such means that said friction is set over the loading force of a shoe spring, and the friction member 32 is molded out of spring steel or plastics and pressed into the internal wall of the hole part 18b unforcedly. And if a lining is worned in excess of the specified clearance, the clearance adjusting function can be realized by moving a piston 18 only to the right as much as the worned clearance. Furthermore, when the pressure in a liquid pressure chamber 24 becomes over the preset relief pressure by a value spring 46 due to high braking force, a valve body 50 is separated from a valve seat 54a, and the liquid pressure supplied from a master cylinder to the liquid pressure chamber 24 is also supplied to a back chamber 26 to move an adjustment piston 16 together with a piston 18 so that the clearance adjusting function will be cancelled and therefore no excessive adjustment will be executed.

Title: Hydraulic driving circuit for hydraulic machinery
Inventor: NOZAWA YUSAKU
IPC: E02F9/22
Filed: 1994-06-20
Abstract: PURPOSE:To switch over the regeneration and non-regeneration of a regeneration valve according to the amount of operation without using pilot pressure. CONSTITUTION:When the amount of operation of an operation lever 23 in Y direction is rather small and a flow rate Qr passing a fixed choke 32 is below a specified limit, a regenerative valve 28 is kept in closed condition and regeneration is not performed. When the amount of operation in Y direction becomes large relatively, and the flow rate Qr passing the fixed choke 32 starts to exceed a specified limit Qt, a pressure difference across the fixed choke 32 which is led into pressure chambers 29 and 30 through pipes 7a and 11 exceeds a specified pressure difference, and thus the regenerative valve 28 opens against the force of a spring 14. By this, a rod side pipe 5 is connected to a bottom side pipe 9 through pipes 7a and 7b to feed pressurized oil Qc exceeding a specified flow to the bottom side pipe 9. Thus the flow fed to a hydraulic cylinder 2 becomes Qb+Qc so as to increase the speed of the hydraulic cylinder 2.
