Title: Steel making method of not discharging cao-base slag having decay characteristic
Inventor: YAMAMOTO SATOMI
IPC: C21C1/02
Filed: 1979-01-13
Abstract: PURPOSE:To avert the formation of a large amount of decayable slag by pre-dephosphorizing and desulfurizing raw material molten iron for steel making beforehand in a suitable range then separating the same from molten slag and charging it into a converter, refining the same to steel with a small amount of CaO-base slag and circulating the slag formed at that time to a blast furnace. CONSTITUTION:Molten iron is pre-dephosphorized and desulfurized to a range where dephosphorization and desulfurization may be done relatively easily, by Na2 CO3-base or CaO-base slag. At this time, the Si in the molten iron is let to remain relatively largely to suppress the extent of desiliconization. Next, this molten iron is separated from the molten slag and is charged into a converter, into which quicklime, fired dolomite, etc. are added as slag forming agents to make basic slag, thence C and residual P and S are oxygen-blown. At this time, the Si in the molten iron is oxidized to SiO2 and becomes slag of relatively low basicity, thus it becomes slag free from decay characteristic by water and since a large amount of FeO is also contained, the slag is suitably disintegrated after solidification and is returned to the blast furnace.

Title: Electrophotographic developing toner
Inventor: IDE YUKIO
IPC: G03G9/087
Filed: 1981-01-13
Abstract: PURPOSE:To improve peeling or separation of a colorant from magnetic fine powder and deterioration of a toner due to mechanical shock and shearing stress, by surface-treating the colorant or the magnetic powder with a substance same as or similar to a matrix polymer. CONSTITUTION:A colorant and/or magnetic fine powder is surface-treated with a substance same as a matrix polymer or approximate to the matrix polymer by <=3.0, preferably, <=2.0 in the difference of solubility parameter between this substance and the matrix polymer. This surface treatment method is embodied by graft-copolymerizing a monomer with the surfaces of the colorant or the magnetic powder, thus permitting the colorant or the powder to be strongly combined with the matrix polymer and its dispersion to be enhanced extremely favorably. For example, when polystyrene is used for the matrix polymer of the toner, styrene is graft-copolymerized with the surface of carbon black.

Title: Method for controlling speed of transfer press
Inventor: OKADA KAZUTOSHI
IPC: B21D43/05
Filed: 1991-01-14
Abstract: PURPOSE:To solve the troubles of breaking of the transfer mechanism or the troubles of remarkable damaging of the durability and the transfer precision on the conventional transfer press, to avoid the transfer mechanism from applying the large impact with the start, the stop and the inching of the press slide before occuring and to protect the transfer mechanism. CONSTITUTION:The transfer press having the transfer mechanism 13 is driven by rotating the eccentric shaft 9 which is the driving shaft of the press slide 5. By observating the driving speed of the above press slide 5, the start or stop of the press slide 5 is allowed only at the time that the driving speed is under the safety limit speed of the prescribed transfer mechanism 13 lower than the stationary press working speed. And the feature is that the press slide driving speed is controlled with the prescribed changing rate so as not to apply the excess impact of the acceleration or decceleration from the speed of starting time of the driving speed to the stationary press working speed against the transfer mechanism.

Title: Video signal recording circuit
Inventor: HIROSE KOUICHI
IPC: H04N5/922
Filed: 1982-01-13
Abstract: PURPOSE:To reduce the voltage level of a video signal recording circuit, by supplying the output of a clipping circuit to the voltage-current transistor of an FM modulator. CONSTITUTION:A video signal having the edge of a synchronizing signal fixed at a certain DC current voltage level is supplied to an input terminal 1 and then amplified by a differential amplifier to be extracted at the collector side of a transistor (TR)33 in the form of voltage. This amplified signal receives a proper DC level shift and division of signals to be delivered to a terminal (f) as well as to a voltage-current TR13 of an FM modulator. This signal delivered to the terminal (f) is negatively fed back to the 2nd input terminal (a) of a differential amplifier. Thus a feedback type preemphasizing circuit containing a clipping circuit within a loop is formed as a whole. As a result, the voltage level can be reduced for a video signal recording circuit.

Abstract: PURPOSE:To suppress surface defects of an epitaxial growth film and generation of dislocation by forming a polycrystalline or amorphous film of the same material as a substrate in advance at the surface a round counterbore which is formed in a susceptor. CONSTITUTION:A polycrystalline silicon film 10 is formed at the surface which includes the round counterbore 8 of a susceptor 6 by the CVD method. Next, a substrate 7 is placed and loaded on the round counterbore 8 of the susceptor 6, and then it is heated while rotating the susceptor 6 on introducing carrier gas H2 into a reaction furnace 1. At this time, until the temperature of the susceptor 6 reaches 1000 deg.C, the bonding by a film 10 between the substrate 7 and the susceptor 6 does not occur, and the substrate 7 rotates on its own axis inside the round counterbore with the rotation. And at the point of time when the susceptor temperature exceeds 1050 deg.C, light bonding occurs between the substrate 7 and the susceptor 6, and the substrate is fixed. When the temperature rise advances and the substrate temperature reaches 1100 deg.C, gas etching of the substrate 7 surface by HCl is done. Next, after stopping supply of the HCl gas, material gas 3 is introduced so as to do epitaxial growth, and a silicon epitaxial growth film of specified thickness is formed.
