Abstract: PURPOSE:To make a device compact having small pressurizing force and prevent a molded product from getting cracked by carrying out the compression molding process consisting of preforming by means of a die press and final molding by means of a hydrostatic press for powder in the powder metallurgical process. CONSTITUTION:When constant characteristics are provided to a molded product at the time of preforming by the pressurizing force or the force more than that for dealing with the molded product and molding is carried out in the magnetic field with an anisotropic magnet such as Ba or Sr ferrite, preforming of powder is carried out by a die press with the pressure of retaining said characteristics or the pressure more than that, and the required molded product can be manufactured by a hydrostatic press thereafter. Thus, the die press can be compact, and as a liquid impermeable bag is fitted compressively on the surface of the molded product even at the time of reducing hydrostatic pressure, cracks are not generated, and the grinding process thereafter can be saved or reduced to manufacture the molded product inexpensively and with high yield. The die press with lifting is used for preforming, and an upper punch is lifted up properly at the time of releasing after preforming to prevent the molded product from getting cracked.

Title: Treatment of clad material
Inventor: YASUI TAKESHI
IPC: B21C1/00
Filed: 1982-05-06
Abstract: PURPOSE:To prevent the core material of a clad material from receiving the influence of an atmosphere during heat treatment, in carrying out the heat treatment of the clad material consisting of a core material and an outer peripheral material made of a different kind of metals, by coating the core material with a material hardly reactive in a heat-treating atmosphere. CONSTITUTION:In preparing the frame of spectacles, a clad material consisting of Ti or a Ti alloy as a core matrial and an Ni alloy excellent in corrosion resistance as an outer peripheral material is used. Because Ti or the Ti alloy is easily susceptible to hydrogen brittleness due to a hydrogen atmosphere in heating the clad material in the hydrogen atomosphere during the production process thereof, Ti or the Ti alloy in the exposed part of the core material is coated with Ni, Cu, Cr, Co or an alloy thereof hardly reactive with hydrogen. As the result, heat treatment can be carried out without generating hydrogen brittleness of Ti or the Ti alloy of the core material.

IPC: G11B5/127
Filed: 1994-04-13
Abstract: PURPOSE:To prevent an increase in magnetic resistance by mispositioning of magnetic films and to improve recording and reproducing efficiency and reliability by providing the front side and rear side joint surfaces of core block half bodies where gaps are formed with joint part magnetic films. CONSTITUTION:The rear side joint surfaces opposite to the front side to be formed with at least one of the gaps of the core block half bodies 1a, 1b formed with magnetic metallic films 3a, 3b between nonmagnetic substrates of a composite type magnetic head in which magnetic paths are constituted of the magnetic films are provided with the joint part magnetic films 40. The joint part magnetic films 40 consist of the magnetic material having the high saturation magnetic flux density to magnetically connect the magnetic metallic films 3a, 3b to each other. As a result, the joint part magnetic films 40 absorb the mispositioning of the magnetic metallic films on the rear side even if such mispositioning arises at the time of joining the core block half bodies to each other. The magnetic resistance does not, therefore, increase and the deterioration in the electrical characteristics is prevented. The recording and reproducing efficiency and the reliability are improved.

Filed: 1991-03-15
Abstract: PURPOSE:To prevent rising of load current from deteriorating even if inductance component of line increases by feeding a load with a main power supply voltage superposed by an auxiliary power supply voltage when the load current is lower than a predetermined set level. CONSTITUTION:Positive pulse main power supply B11 and auxiliary power supply B12 are connected in series whereas negative pulse main power supply B21 and auxiliary power supply B22 are also connected in series. When a set pulse exceeds a threshold level, a control circuit 50 turns a positive pulse main power supply thyristor T11 ON and when the load current is lower than a set level, a control circuit 40 turns a positive pulse auxiliary power supply thyristor T12 ON. Consequently, a superposed voltage higher than the main power supply voltage B11 is applied onto a line 80 and the load current rises sharply. Similarly, control circuits 60, 70 turn negative pulse main power supply thyristor T21 and auxiliary power supply thyristor T22 ON, respectively, according to the set pulse or the load current value.
