Title: Method and apparatus for production of high-carbon ferrochrome
Inventor: FUKAGAWA MAKOTO
IPC: C22C33/04
Filed: 1986-06-05
Abstract: PURPOSE:To decrease the content of P in ferrochrome in a process for producing the ferrochrome by a counter current moving bed type smelting furnace using a coke packed bed by separating the slag derived from the ashes generated by the combustion of coal, etc., to molten ferrochrome and molten slag and extracting the same. CONSTITUTION:Fuel essentially consisting of C and H is blown together with O2 and if necessary, steam, into a combustion chamber (f) from tuyeres 4 formed in the lower part of the coke packed bed (b) under a Cr ore packed layer (a) in a furnace body 1. The fuel is the gasified to form the reducing high-temp. gas essentially consisting of CO and/or H2. The gas rises in the bed (b), heats and melts the Cr ore in the bed (a) and is recovered from the upper part of the furnace body 1. The formed Cr ore melt drops in the bed (b) and is subjected to a heat exchange with the counter current of the above-mentioned high-temp. gas and is reduced by the coke; at the same time, the molten metal is carburized. The molten ferrochrome (d) and molten slag (c) formed in such a manner are separated from the molten slag (e) derived from the ashes in the carbonaceous material formed in the chamber (f) by a gate 7 and the extracted from a tap hole 5. The molten slag (e) is extracted from a slag off port 6.

Title: Centrifugal deoiling device for small product
Inventor: SAKAMURA YOSHIICHI
IPC: B04B3/02
Filed: 1980-09-22
Abstract: PURPOSE: To improve the efficiency of a process by discharging deoiled small products automatically from a deoiling drum directly under high speed rotation of the drum.  
     CONSTITUTION: When small products are discharged from above a discharge drum 14 into a deoiling drum 11 while a discharging disc 16 is positioned in the bottom part of the drum 11, they are rolled to the circumferential edge part of the disc by a circular conical surface 18 and contact with the inside circumferential surface of the drum 11. thereupon, when the drum 11 is rotated at high speeds, the small products are pressed to the inside circumferential surface by centrifugal force, and the oil stuck on the products is feed and expelled from small holes 11a by the effect of centrifugal force. When the disc 16 is moved upward up to the top end of the drum 14 by a shaft 17 without rotated, the small products drop over the top end of the drum 14 onto the circumference and go toward a chute 15, thus the deoiling and discharging of the products are automatically under the rotation of the drum 11.

Title: Filter circuit
Inventor: KUWABARA HISAO
IPC: H03H11/04
Filed: 1988-05-30
Abstract: PURPOSE:To reduce the minimum operating voltage and to simplify the configuration of the circuit in a filter circuit provided with the 1st - 3rd transistors whose emitters are respectively connected with a reference potential point by connecting an impedance changing element to the base of the 3rd transistor and reference potential point. CONSTITUTION:When the input AC iIN of an input signal current source IIN is zero (iIN=0), the collector currents of transistors Q1-Q5 and Q5 are equal to the current I1 of a current source I1 and no DC flows to an output terminal OUT. When the AC current iIN is other than zero (iIN=0), on the other hand, the input impedance of this circuit is a resistance re(Q1) equivalent to the emitter of the transistor Q1 and re(Q1)=VT/IC(Q1). The VT is the thermal voltage (=kT/q) of electrons and about 26mV at the room temperature. When the IC(Q1) is set to 100muA (IC(Q1)=100muA), the re(Q1) becomes very small to 260OMEGA. Moreover, when the iIN is set to 10muAP-P (iIN=10muAP-P) in this case, the amplitude of the input voltage becomes very small to 2.6mVP-P. Therefore, the minimum operating supply voltage can be made extremely low.

Title: Gas cut-off device and gas cut-off method

IPC: F17D3/00
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To avoid outflow of gas by cutting off the gas at high temperature such as a fire disaster. SOLUTION: A pressure in a gas meter 11 or a gas pipeline 12 is detected by a pressure sensor 13. A microcomputer 14 calculates a pressure change rate within a gas supply passage based on an output of the pressure sensor 13 at a predetermined sampling time measured by a time counter 15, and determines whether or not the pressure change rate is greater than a predetermined reference value. When the pressure change rate in a short time is greater than the predetermined reference value, the microcomputer determines that a pressure buildup occurs accompanied with a sharp temperature increase owing to fire disaster or the like, and outputs a cut-off signal and cuts off the passage of the gas by an cut-off valve.

Title: Formation of metallic film
Inventor: MATSUDA HIROSHI
IPC: C23C18/31
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To obtain a metallic film excellent in uniformity on a material to be plated with excellent reproducibility by electroless plating method by depositing an organic palladium complex or an organic mixture containing the organic palladium complex on the material to be plated by Langmuir- Blodgett's method in a non-catalytic adsorption process of electroless plating. SOLUTION: A film composed of the organic palladium complex or the organic mixture containing the organic palladium complex is deposited by Langmuir-Blodgett's method(LB method) and electroless plating is executed using the deposited film as a catalytic layer. Since the catalytic nucleus layer excellent in uniformity is formed by the method, the metallic film excellent in uniformity is formed on the material to be plated with excellent reproducibility by electroless plating method. In such a case, the organic portion in the film is decomposed by irradiating the deposited LB film with ultraviolet ray and the effect of reduction reaction in the subsequent plating process is improved. The removal of the organic material is further accelerated by further heating and firing the film irradiated with ultraviolet ray.
