Title: Device and method for preuenting parasitic electricdis charge in magnetic disk drive
Inventor: SAMUERU EICHI GEIRUBURESU
IPC: G11B5/60
Filed: 1990-02-15
Abstract: PURPOSE: To prevent electric discharge between a read/write head and the surface of a magnetic disk by applying to the conductive surface a DC voltage nearly equal to one that is applied to the read/write head. CONSTITUTION: A bias is imparted to the surface 26 of a magnetic disk at the same DC voltage level as one applied to a read/write head. As a result, two 'plates' are on the same DC voltage level for a parasitic capacitance between the surface 26 of the magnetic disk and the read/write core 12, 14, so that no charge is generated to this parasitic capacitance cg. Consequently, an electrical discharge can be removed between the read/write head 10 of the magnetic disk drive and the surface 26 of the magnetic disk, preventing error data or unnecessary noise from generating in a read output signal.

Title: Biller for hot extrusion
Inventor: YAMANO TAKUMI
IPC: B21C23/00
Filed: 1979-03-26
Abstract: PURPOSE: The billet which is made difficult to cause thickness deviation by forming a small-diameter part of a slightly smaller diameter over the wide range of the intermediate of the billet in its axial direction and limitng the contact surface of the billet with the container inside surface to the small segment between the leading end part and trailing end part.  
     CONSTITUTION: A billet 1 assumes nearly a cylindrical shape and is made into a cylindrical shape having a small-diameter part 2 of an equal diameter made slightly smaller than the outside diameter of the both end parts over the wide range of the intermediate part of its axial direction. It is desirable that the difference in the outside diameter between said small-diameter part and the leading end part 3 and trailing end part 4 is made, e.g., 0.2W1mm. It is also desirable that the portions near the boundaries between the small-diameter part 2 and the leading end 3 and trailing end part 4 are connected gently by tapers or the like. As a result of this, the foregoing small-diameter part 2 has no contact with the container inside surface just before extrusion, at the time of making pipe, hence the one-side cooling at this segment is prevented and the thickness deviation of the product are reduced.

Inventor: OOTA RIYOUZOU
IPC: C02F3/08
Filed: 1982-03-06
Abstract: PURPOSE:To save power required for rotation, by controlling specific gravity of a rotary body obtd. by assembling a large number of contact plates to <=1.0, and alleviating load applied to rolls for supporting the shaft of the rotary body or bearings for supporting it. CONSTITUTION:Contact plates 1 are made of low-ratio expanded plastic plates of, e.g., 0.1-0.6 in specific gravity so as to give proper rigidity. They are fixed to a rotary shaft of specific gravity as small as possible, e.g., a hollow shaft 2, and tires 3, 3' used for fixing a rotary body to the shaft 2 are supported by pairs of supporting rolls 4, 4' and 5, 5'. When the shaft 2 is arranged near the level of a water treatment pond, the weight of the rotary body is alleviated by its buoyancy, thus permitting drive of the rotary body with a small power through a reduction motor 9, chain wheels 7, 6, 6', a chain 8, the rolls 4, 4', and the tire 3.

Title: Branch switch drive system
Inventor: HIGAKI TETSUSHI
IPC: H04B1/74
Filed: 1984-02-28
Abstract: PURPOSE:To attain ease of switch control by applying a switch control at the same time to the switch of an intra-office line into a matrix line (2nd intra-office line) and the opening of a spare line (2nd intra-office line) from the matrix line by means of one drive signal in a digital network switching device. CONSTITUTION:Drive sections V1-V3 are differential winding relays and when a current flows to coils l1-l4 (in a way of full selection), contacts S1-S3 of a switch section 1 are opened, and when a current flows to the l1 and l2 only (or l3 and l4) (in a way of half selection), contacts are opened. In inputting a drive signal (b) to, e.g., a drive terminal (b), a current I1 applied full selection to the drive section V1 and half selection to the drive section V2 so as to connect the intra-office line DR to a network line NL. If a fault takes place in the line NL, the intra-office line DR is connected switchingly to the matrix line M. That is, the contact S1 of the switch section 1 is turned off and the S2 is turned on. The contact S3 is turned off in this case so as to prevent mis-connection of the spare line E to the line M. The selection control of each contact of the switch section is attained by using a diode D5 at the switching so as to have only to apply a signal C to a drive terminal (c).

Abstract: PROBLEM TO BE SOLVED: To accurately design even by a memory of small capacity without deteriorating the analysis accuracy of a threedimensional electromagnetic field simulator by modeling a part of a connector based on the periodic boundary condition and then extracting and dividing a model. SOLUTION: It is decided whether the periodic boundary condition of a three-dimensional electromagnetic field model produced based on the physical information on a connector is satisfied or not.

Then the model is divided at the part where the mismatching of impedance occurs, and a model file is produced. Then an equivalent circuit produced based on the impedance, the inductance, etc., that are decided by the electromagnetic field analysis is analyzed by a circuit simulator. Then a characteristic waveform is simulated.
