Title: Continuous desiliconization treatment of molten iron
Inventor: KAMANO HIDEYUKI
IPC: C21C1/04
Filed: 1988-12-05
Abstract: PURPOSE:To suppress the wear of the bottom part of an incline pouring trough and to prevent splashing of a molten iron by adjusting the infiltration depth of a desiliconizing agent for blowing up to the part right above the bottom of the incline pouring trough. CONSTITUTION:The molten iron 8 which is tapped from a blast furnace and is supplied from a molten iron trough 7 is transported via the incline pouring trough 9. The desiliconizing agent is blown via a projecting pipe 6 by a charging device 3 consisting of a hopper 3-1 and a rotary valve 3-2 and a blower 5 to the molten iron 8 in this incline pouring trough 9. The tilting angle of the incline pouring trough 9 of the above-mentioned method for continuous hearth desiliconization treatment of the molten iron 8 is detected by an angle gage 12 and the depth of the molten iron stored in the incline pouring trough 9 is determined. The depth of the infiltration of the above-mentioned desiliconizing agent for blowing into the molten iron is adjusted by a control device 13 to the part right above the bottom of the incline pouring trough 9 according to the change in the depth of the stored molten iron. The above mentioned adjustment is executed by changing the flow rate and pressure of the gas for blowing the desiliconizing agent, the distance between the front end of the projecting pipe 6 and the level of the molten iron stored in the incline pouring trough, etc. The wear of the incline pouring trough 9 and the splashing of splashes are prevented in this way and the desiliconization efficiency is improved.

IPC: B41J2/385
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To realize a smooth picture and a sharp edge by differentiating the size of a first set of apertures substantially from that of a second set of apertures. SOLUTION: In a DEP device, a voltage V1 is applied to the sleeve of a magnetic brush assembly 3, a voltage V2 is applied to a linear shield electrode 6b, and a variable voltage V3 takes a range from V30 to V3n for individual control electrodes 6a.

Title: Static induction transistor and manufacture of static induction transistor
Inventor: SHOJI HIROYOSHI
IPC: H01L29/80
Filed: 1993-12-07
Abstract: PURPOSE:To prevent the generation of a gate contact failure and to increase the yield of the manufacture of a static induction transistor without using a complicated process by a method wherein a taper having a specified angle is provided on the sidewall of a groove encircling at least one part of a source region. CONSTITUTION:An N<-> epitaxial layer 2 is formed on an N<+> semiconductor substrate 1. A groove 4 is formed in the side of the surface of the layer 2 and the angle A of a sidewall 4a, on which a nitride film 5 is formed, of the groove 4 is set at 60 to 80 degrees. Moreover, oxide films 6 consisting of a silicon oxide are respectively formed under the bottom of the groove 4 and on the side of the surface of the film 2 and a gate diffusion window 7 is provided from the sidewall 4a of the groove 4 to the layer 2 and makes ohmic contact with a gate electrode 9. When the groove 4 is formed by dry etching, an etching is performed using SF6+CCl4 gas. Whereupon, as the etching is performed while a polymer is applied the sidewall 4a, a taper is formed on the sidewall 4a. As a result, a reduction in the yield of the manufacture of a static induction transistor, which is caused by a gate contact failure or the like, can be prevented from being generated.

Title: Casting face of mold for casting continuously metal by movable wall
Inventor: YUUGU RUGURAN
IPC: B22D11/06
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent the microcracks by forming the circumference of dimples to a lobe form at the casting surface of the mold by the movable mold including the dimples of the circular or elliptic general shape. SOLUTION: The microcracks are generated by the thermal gradient which generates stress in the product skin solidifying on roll surfaces. The stress is decreased by providing the roll surfaces with wrinkles and trapping air or inert gas into these recessed parts before the contact of molten metal to form the blanket of gas. This blanket decreases the thermal gradient of the skin. The lobe (a flower pedal notch shape) shapes is so determined as to equal the surface area of the dimples 2 to the surface area in the case of the circular shape and the radius thereof is 1.22 times the radius in the case of the circle. The length at the circumference of the lobe shape is most adequately 1.1 to 1.5 times the circumferential length in the case of the circle in which the surface areas of the dimples 2 are equal. The shape to prevent the generation of the microcracks is thus obtained.

Title: Method for forming heat transfer path and heat transfer path device
Inventor: RUBENS PAUL A
IPC: H05K1/02
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To reduce heat transfer effects in the solder boundary surface between a microprocessor and a circuit board by providing a first part, that is nearly as thick as a printed circuit board for mounting a heat conduction substrate and a plurality of second parts spaced apart along the periphery of the substrate. SOLUTION: A heat sink 90, with an area that is equal to or larger than a substrate 50, is fixed to a tentative surface 70 of a printed circuit board(PC board) 52 and is separated from the PC board by a heat insulation spacer. The substrate 50 is useful as an effective heat transfer path for transferring heat from an IC 42 to a heat sink 90. An IC 42 is mounted to the substrate, and a normal heat conduction path is omitted for direct heat conduction to the PC plate 52. The air gap between the substrate 50 and the PC board 52 is formed, and other heat transfer paths are avoided.  Therefore, the heat conduction substrate 50 is inserted and fitted into the through-hole opening of the PC board 52, and an integrated circuit 42 with a lower surface 82 is brought into thermal contact with a first surface with the same area as that of the lower surface of the integrated circuit of the substrate for fixing, thus forming a heat transfer path.

Title: Metallic tube-containing optical fiber cable
Inventor: KAJIWARA KENTARO
IPC: G02B6/44
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To obtain a metallic tube-contg. optical fiber cable which is extremely low in transmitted light loss even if being used for a long term at a high temp. in a severe atmosphere filled with gaseous hydrogen sulfide, etc., by using a metallic tube, which has a clearance from an optical fiber and is a hydrogen sulfide resistant alloy contg. a specific ratio of Ni. SOLUTION: The metallic tube 6 of the metallic tube-contg. optical fiber cable 2 having a clearance between the optical fiber 5 and the metallic tube 6 is a hydrogen sulfide resistant alloy contg. 30 to 70wt.% Ni. If the Ni content is below 30wt.% the performance to withstand practicable use conditions is not obtainable. If the content exceeds 70wt.%, the resistance to the hydrogen sulfide is approximately equal but since the costly Ni is contained at a high rate, the cost is high and such high cost is not practicable. The content of Cu in this hydrogen sulfide resistant alloy is preferably >=1 to <=3wt.%. If the Cu content is below 1wt.%, the hydrogen sulfide resistance is deteriorated. If the content exceeds 3wt.%, the mechanical properties are deteriorated.

Filed: 1993-12-08
Abstract: PURPOSE:To establish a method for making operational control of a valve element to be operated by a solenoid directly or indirectly with good accuracy in responsiveness regardless of the magnitude of a command input signal. CONSTITUTION:A solenoid proportional valve 1 is equipped with a valve element 9 to be put under operational control directly or indirectly by solenoids 3a, 3b and a position sensing device 16 to sense the operating position of the valve element 9. The operational control of the valve element is performed so that an operating position signal for valve element 9 sensed by the device 16 and a command input signal to direct the operating position of the valve element 9 are fed to an computational amplifier 19 and that the magnetic forces of the solenoids are controlled with the computing result signal given by the computational amplifier 19, wherein the gain of the amplifier is made small temporarily, if the command input signal is large, and made large if the signal small during the period that the valve element makes movement to the specified operating position from the time the computing result signal is issued. Thereby there is no risk of dull or overshoot in the respond operation of the valve element regardless of the magnitude of the command input signal, and operational control can be conducted with good accuracy in the response.
