Title: Disk device
Inventor: TATEISHI HISAO
IPC: G11B21/08
Filed: 1990-07-31
Abstract: PURPOSE:To ensure high accuracy even in a long seeking state by detecting a cylinder No. where a moving read/write head is positioned by a cylinder No. detection means of a CPU and comparing the detected cylinder No. with a desired one for confirmation of match between both cylinder Nos. CONSTITUTION:A CPU 1 contains a cylinder No. detection means 1a which issues a read command to a disk controller 2 in order to detect a cylinder No. where a moving read/write head is positioned for execution of the control. Then the CPU 1 calculates the number of moved cylinders from the cylinder No. where the present read/write head is positioned and a desired cylinder No. serving as a seeking destination. The CPU 1 gives a command to a servo controller 3 to perform the seeking operations equivalent to the number of moved cylinders. At the same time, the equality is checked between the detected cylinder No. and the desired one with the comparison of them. As a result, the physical position of a head under seeking can be detected. Thus it is possible to accurately seek a desired cylinder even in a long seeking state.

Title: Charpy impact testing method
Inventor: MASUDA KIICHI
IPC: G01M7/08
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To calculate a total displacement value of a test piece by a method wherein a hammer lifted to a specified height is made to work on a test piece in the direction of a load to record an impact force in a waveform per sample in the period while the hammer impacts and breaks the test piece crossing it. SOLUTION: In a power detector 1, a hammer lifted to a specified height works on a test piece in the direction of a load by kinetic energy and an impact force is detected per sampling by an output from a strain gauge in the period while the hammer impacts and beaks the test piece crossing it. An output signal from the power detector 1 is inputted into an amplifier 2 and then, into a waveform memory 3 and subsequently, into a computer data analyzer 6. In this process, an impact force is measured from a relational expression of the impact force as applied and a displacement value. At the beginning of the impact, the impact force is determined at the rising thereof and the speed of the hammer at the moment is determined by the lift height of the hammer and the acceleration of the gravity.  Changes in the speed is calculated according to changes in the impact force and the displacement value is converted to determine a total displacement value.

Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To generate sufficient lead control power even when the number of revolution of a rotary drum is changed and to stably travel a tape by providing a projection on an outer periphery of an upper drum and reducing the projection amount of the projection when the number of revolution of the upper drum is increased. SOLUTION: When the upper drum 33 is rotated, and centrifugal force is operated on a projection member 39, an arm is rotated counterclockwise while making a bend part a fulcrum, and the projection amount of the projection part is reduced. The size of the centrifugal force proportionates to square of the number of revolution, and when the number of revolution of the upper drum 33 is R1, the projection part is moved inside to the lower position than the outer periphery of the upper drum 33, and when the number of revolution is changed, the elastic modulus of the bend part is selected so that the projection part becomes the prescribed projection amount from the outer periphery of the upper drum 33.  The sizes of a step between the upper drum 33 and fixed lower drum 34 and a groove 37 are set so that floating of a magnetic tape 36 and the lead control power become optimum when the number of revolution is R1, and when the number of revolution of the upper drum 33 is R1, the magnetic tape 36 is made travel stably along a lead 35 only by the lead control power occurring due to the floating of the magnetic tape 36.

Title: Hot rolling method
Inventor: HISHINUMA ITARU
IPC: B21B1/22
Filed: 1984-10-01
Abstract: PURPOSE:To reduce a sheet crown and to stabilize a sheet profile through a rolling cycle by setting a roll shifting pattern in consideration of the distribution of roll wear and the thermal expansion of roll. CONSTITUTION:A sheet 2 is shifted within a range that its both ends are kept from slipping out of the ground taper part 1' of a roll 1. On the other hand, as the roll 1 causes its thermal expansion with the advance of hot rolling, the upper limit of an EL value i.e. the gnawing amount EL of the taper part 1' into the sheet 2, is set to the limit value of a body-stretched shape of sheet 2 due to the thermal expansion of roll 1 by gradually decreasing the EL value to be set in conformity with the thermal expansion of roll 1. Therefore, the wear of roll 1 is dispersed along a pattern P prepared to shift the upper limit of EL value in a minute region along a curved line (l) to achieve the reduction of a sheet crown and the stabilization of a sheet profile.

IPC: B24B19/00
Filed: 1989-08-07
Abstract: PURPOSE:To polish a wire material under a uniform contact pressure by providing a movement means which moves relatively the wire material and polishing members in the wire material direction. CONSTITUTION:At the time of a polishing operation, each polishing member 4 is wound around the outer perimeter of a wire material 6 more than (1/the number of the polishing member) times as a turning member 3 makes a turning movement with the wire material 6 as a center. Polishing members 4 are wound around the wire material 6 under a fixed tensile strength by the rotation of the turning member 3, so polishing members 4 are wound around the outer perimeter surface of the wire material 6 under a predetermined contact pressure. Under this condition, a movement means 5 moves either of the wire material 6 and polishing members 4, for example, polishing members 4 in the direction of the center line of the wire material. As a result, polishing members 4 make a sliding movement in the generation line direction as they are polishing the outer perimeter surface of the wire material 6, and such as attachment as silicon or the like is being removed by polishing its outer perimeter surface.
