Title: Oxide/sulfide dispersion strengthened steel
Inventor: SHINPO YUKIO
IPC: C22C38/00
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To stably produce a strengthened steel by specifying particle size and the content of oxide/sulfide particles to be incorporated into the steel and dispersing combined particles, which precipitate a copper sulfide on the surface of oxide particles thereby preventing oxide particles to be added in a molten steel from aggregating and coarsing. SOLUTION: Oxide/sulfide particles of 0.01-0.06 μm particles are incorporated into the steel by a volume % of 0.05-2%. Oxide/sulfide particles are dispersed in the steel by using combined particles which precipitate a copper sulfide on a surface of oxide particles as taking an oxide particle for a nucleus. In the case a fine oxide is dispersed in a steel, because sulfur is an element having an activated surface, the sulfur is stuck to a surface of the oxide. The sulfur stuck to surface reacts with copper in a steel to produce a sulfide. Boundary energy of a copper sulfide with a molten metal is small, the oxide particles coated, a surface of which is coated with sulfide copper, are not flocculated. The method, by which a combined oxide is dispersed in the molten steel, is used for dispersing the fine oxide in the molten steel.

Abstract: PROBLEM TO BE SOLVED: To improve operability of a top plate lifting/lowering pedal arranged in a supporting leg and to prevent an erroneous operation of the pedal when a plurality of equally shaped tables are housed closely to each other. SOLUTION: When a supporting column 24 raised in a substantially horizontal supporting leg 2 is expanded/shrunk by means of an expansion mechanism arranged inside the supporting column 24, a top plate 26 supported by the supporting column 24 is freely lifted/lowered. For overlapping tables 1, which are same in the shape and in the size, to this table 1, the rear and front parts of supporting legs 2 in other tables 1 are brought closely to the front and rear sides of the supporting leg 2 of this table 1.

Title: Burner for liquid fuel
Inventor: WATANABE EIICHI
IPC: F23D3/18
Filed: 1982-04-21
Abstract: PURPOSE:To suppress a rise in temperature around a burner and to cause to have steady fire extinguishing properties, by a method wherein a top part is located above an inner fire grate of a wick guide tube, and a punched part, where a part except coupling parts is punched, is formed in the top part to suppress thermal conduction to said inner fire grate from the top part. CONSTITUTION:In a top part 4, facing a burner 19, of a wick guide tube 2, the part except a plurality of coupling parts 6 located in the proximity of an inner flame tube 17 is all punched. Even if the heat is going to transfer to an inner fire grate part 3 from the top part 4 of the wick guide tube 2 which is heated to a high temperature by the radiant heat from the burner 19, there remains nothing but the coupling parts having a very small area, and thereby a thermal conduction may be almost cut off. This enables lowering of temperature at the inner fire grate and below the inner fire grate, providing steady fire extinguishing properties, permitting the reduction of production of tar.

Filed: 1984-04-06
Abstract: PURPOSE:To reduce the dependence of a delay circuit in a semiconductor IC device upon a supply voltage by actuating a CMOS delay circuit under a bias voltage which cancels a variation of the supply voltage. CONSTITUTION:A P type MOSFETQ4 and an N type MOSFETQ5, Q6 are serially connected between a supply voltage VCC and the earth, whereby a bias circuit is formed, and a bias voltage for canceling a variance of the voltage VCC occurs. This bias voltage controls a P type CMOS delay circuit of a semiconductor IC device, Q-type MOSFETQ1 and Q2 and an N type MOSFETQ3 of a constant current source serially connected, whereby a temperature dependence of the CMOS delay circuit for delaying rise, etc., of an input phiin can be reduced. Accordingly charging and discharging periods of a capacitor due to a delay output is kept constant irrespective of the variation of the supply voltage. As a result, a series of time series action timing signals such as the dynamic RAM can be formed with the necessary minimum margin, and a stable high-speed acting cycle can be executed.
