Inventor: OKAZAKI SHINICHI
IPC: F16N7/38
Filed: 1979-06-05
Abstract: PURPOSE: To improve efficiency with a simple structure by forming a viscosity pump from the thrust collar of a thrust bearing apparatus, the outer peripheral surface of a rotary plate, and pum casing, and by allowing oil to circulate into an oil tank through an oil cooling apparatus.  
     CONSTITUTION: A viscosity pump is formed of the outer cylindrical surface 5a of a thrust collar 5 and a pump casing 9a which is arranged in annular form, keeping a prescribed clearance on the outer peripheral side of the cylindrical surface. The exit 9c of the casing 9a is connected with an oil tank through a conduit 2a. With such a constitution, the pressure generated in the pump can be calculated with the length (l) of pump casing, depth (h), width (b), circumferential speed U on the thrust collar, flow amount Q, and viscosity μ of lubricating oil. Therefore, when these values are designed properly, the pressure corresponding to the pressure loss in the circulation conduit and oil cooling apparatus can be generated, so the efficiency applicable over a remarkably wide range can be obtained.

Title: Optical recorder
Inventor: WADA HIDEHIKO
IPC: G11B7/0055
Filed: 1993-03-29
Abstract: PURPOSE:To achieve a narrowing of a track by suppressing a crosstalk with a sufficient S/N ratio of a signal by erasing a specified part of a mark to record information on an optical recording medium with the irradiation of another light beam after the formation of the mark. CONSTITUTION:A physical change. herein a change from an amorphous to crystalline state, is caused on a recording medium and a focusing spot 21 is controlled to be position so that the center 24a of an area to be erased with the irradiation of a second beam is located at a position in the center between one track and an adjacent track, for example, at the central part between 23a and 23b. Here, a quantity of light of the spot 21 is always suppressed to a level at which an optical recording medium changes to an amorphous to crystalline sate, namely, at which a mark recorded is erased. If so, the state is always crystalline (shaded part) after the passage of the spot 21. Thus, after the formation of the mark 22 by a first beam, the mark 22 is erased partly by a second beam to form a substantial information mark 22a. In the amorphous area, reflection factor and refractive index are different from the crystalline area thereby enabling the reading of a record from this difference.

Title: Electric contact member
Inventor: SHIBATA AKIRA
IPC: H01H1/04
Filed: 1992-02-19
Abstract: PURPOSE:To improve the high-temperature strength of an electric contact material by junctioning a copper alloy base and a silver contact material through metal in iron group or alloy. CONSTITUTION:A copper alloy base and a silver contact material are junctioned through the powder, the particles or the line of metal in iron group or alloy so as to make an electric contact member. The metal in iron group or alloy and the base are welded first by a concentrated current by letting a welding current flow between the contact material and the base while pressing them. Next, the silver contact material softens by heat, and is junctioned in contact with the base while burying the metal in iron group or alloy therein. Hereby, the junction strength between the contact material and the base becomes firm dependent upon the alloy between the metal in iron group or copper. The electric resistance becomes small, depending upon the silver contact material and the base. By these merit, a highly reliable electric contact member can be gotten.

IPC: H03F3/30
Filed: 1979-06-06
Abstract: PURPOSE:To make bias set for output MOSFET at the class AB operation, by providing the temperature compensation means having positive temperature coefficient in the bias circuit. CONSTITUTION:In the push-pull output circuit constituted with a power MOSFET, the circuit is at the class B operation under the idling current (bias) in which the temperature coefficient of FET is zeroed. On the other hand, when the push-pull circuit is biased to the class AB, the temperature coefficient of MOSFETs(Q1, Q2) is negative, but compensation is made with a positive temperature coefficient of the saturation voltage between the collector and emitter of the bipolar transistor Q4 in the bias circuit. That is, since the temperature coefficient of the output circuit is zero, the idling current is set so that the temperature coefficient of the said bipolar transistor Q4 is in agreement with that of MOSFET.

Title: Magnesia-spinel brick
Inventor: TAMAKI TAKEYUKI
IPC: C04B41/87
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a magnesia-spinel brick capable of applying as a refractory for a vacuum degassing furnace, excellent in slaking resistance and hardly causing structural spalling accompanied with slag wetting. SOLUTION: A brick structure is coated with a silica deposited layer by impregnating or coating the magnesia-spinel brick with a colloidal silica solution and then drying to leave, stick and deposit a silica component on the surface and the inside surface of pores of the magnesia-spinel brick. The silica deposited layer plays a role in isolating the brick structure from the contact with the outdoor air and prevents the hydrating reaction of magnesia.  Moreover, the silica component deposited on the surface and the pore inside wall of the brick easily reacts with a liquid component entering from outside such as a slag, in the case that the liquid component such as the slag enters into the pores in the course of operating furnace, to increase the viscosity of the liquid component and thus the silica component has an action of preventing the slag or the like from entering further into the inside.
