Title: Material charging method for cold pilger mill
Inventor: TAMAISHI ZENICHI
IPC: B21B21/04
Filed: 1987-02-18
Abstract: PURPOSE:To prevent degradation in rolling accuracy without generating a clearance between materials by stopping material charging before a fresh charging material contacts the charged material and changing over this state to the charging by a feed carriage, then starting rolling as it is. CONSTITUTION:A charging pusher 13 pushes out the fresh charging material 6'' by the instruction of a charging pusher controller 59 when the fresh charging material 6'' is transferred in front of the pusher 13 and stops said material at some spacing provided between said material and the last charged material 6. The pusher 13 retreats upon ending of the material charging by the pusher 13 and in turn, the feed carriage 21 moves and a motor 24 is driven at low torque by the instruction of a controller 56 to rotate a feed screw 23 and to advance the carriage 21. The front end contacts the final end of the charged material 6 on progression of the fresh charging material 6''. A load cell 51 detects the contact and the controller 56 applies a command to the motor 24 to execute rolling by changing over the driving of said motor to high-torque driving so that the carriage 21 feeds the whole of the materials 6, 6'' in the rolling direction.

Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To cancel the fluctuation of the amplitude of a tracking error signal due to the eccentricity of an optical disk by setting the gain of positioning control of a track based on the obtained amplitude of the tracking error signal. SOLUTION: In this optical disk device, a laser beam LB from an optical pickup 20 is converged/projected on an optical disk 21 and the reflected beam is introduced to a photodetector 22 in the optical pickup 20. A CPU 24 reads out the amplitude of a tracking error signal corresponding to the rotated angle of the optical disk 21 from a memory at the time of ordinary tracking servo operation and the gain of positioning control of a track to be set in a variable gain amplifier 25 is calculated/set based on the amplitude obtained. Consequently, in the optical disk device of three beam tracking method, by measuring the fluctuation of the amplitude of tracking error signal due to the eccentricity of the optical disk and setting a gain in inverse proportion to the measured value for every rotating angle, the fluctuation of gain is canceled.

Title: Lightning arrestor
Inventor: KIMURA JUNICHI
IPC: H01C7/12
Filed: 1988-02-17
Abstract: PURPOSE:To elongate the durable life of a lightning arrestor element by providing a dielectric resistant insulation cylinder with thin-walled portions at several locations to serve as discharge points of high temperature, high pressure gas produced in the dielectric resistant insulation cylinder. CONSTITUTION:Thin-walled portions 2A to serve as discharge points of high temperature, high pressure gas produced in a dielectric-resistant insulation cylinder 2 are formed on the dielectric-resistant insulation cylinder 2 so that the gas breaks through the thin-walled portions 2A and through a porcelain tube 5 to the outside. The behavior of the high temperature, high pressure gas at the time of discharge depends on the relationship between the gas pressure and the thickness of the thin-walled portion 2A. Namely, the gas breaks through the thin-walled portion 2A when it becomes impossible to stand the pressure any more and is discharged outside the porcelain tube 5. As a result, the shock of discharge is much smaller compared with the conventional discharge structure. This arrangement elongates the durable life of a lightning arrestor element 1.

Abstract: PURPOSE:To detect a fault quickly without increasing a database of protocol specification by providing an auxiliary database section of a database section for state estimate processing and fault monitor in addition to a protocol specification database section and detecting a fault of sequence for each input event. CONSTITUTION:When a monitor signal from a monitor line 6 is supplied from a decode processing section 3a of a state analysis section 3, a state estimate processing section 3c applies matching processing between a decoded signal and a data of a state estimate processing auxiliary data section 2a of an auxiliary database section 2 to discriminate whether or not the connection is established. When not established, the state is specified depending on the matching with the state transit rule stored in the protocol specification database section 1. Then the matching between a decode data for each input sequential event based on the specific state and a data in the fault monitor auxiliary database section 2b of the database section 2 is implemented by the fault monitor processing section 3c and quick protocol fault detection is implemented without increasing the size of the protocol specification database.

IPC: G06F9/28
Filed: 1992-02-24
Abstract: PURPOSE:To prefetch a necessary instruction out of a core instruction and a software instruction by a processor. CONSTITUTION:A STAT detection circuit 32 detects a STAT tag indicating the start of a core instruction during the execution of software and sends the derected result to a competition control circuit 31. An EOP detection circuit 35 detects an EOP tag indicating the execution of the succeeding software during the execution of the core instruction and sends the detected result to the circuit 31. The circuit 31 receives these detection signals and dynamically changes the extraction priority order of the core instruction and the software instruction.

Abstract: PURPOSE:To deflect the small diameter work roll into the required shape, and to roll the sheet material into the desired section shape, by backing up the work roll with the sleeve through the intermediate roll, and by shifting the sleeve along the roll axis. CONSTITUTION:The rotary shafts 52, 53, are driven to rotate by the driver. Since threads 56, 57, are cut in opposite directions, the sleeves 43, 44, and the sleeves 46, 47, respectively make movement in opposite directions, that is, so as to mutually approach or to mutually part. Since the sleeves 43, 44, 45, 46, 47, are contacting with the intermediate roll 33, the loading point of the intermediate roll 33 changes depending on the position of the sleeve. Hereby, the longitudinal deflection of the intermediate roll 33 changes, and besides, the deflection of the work roll 32 changes. Accordingly, the sleeve is previously located at the specified position correspondingly to the quality, breadth, and thickness of the rolled material S, and the sheet material of the desired section shape is rolled.
