Title: Cooling method of lance for stirring molten metal
Inventor: SHIRATANI YUUSUKE
IPC: B22D1/00
Filed: 1983-02-09
Abstract: PURPOSE:To extend the service life of a lance for stirring a molten metal and to reduce the cost ratio thereof in the stage of using said lance by feeding water into the metallic pipe of the lance from the upper or lower part thereof after the treatment and evaporating the same thereby cooling forcibly the pipe. CONSTITUTION:A molten metal is stirred and refined by using a lance 3 for stirring a molten metal consisting of a metallic pipe 7 having a gas passage hole 7' and refractories 8 covering the outside circumference thereof. The lance is removed to the outside of a refining vessel after the end of the treatment and a water feed pipe 10 is inserted into the lance through the hole 7' and the water in a tank 11 is fed into the pipe 7 from the lower part thereof. The water fed into the pipe is evaporated by the heat which the lance receives from the molten metal and retains during the treatment. The heat of evaporation thereof and sensible heat are removed from the inside surface of the pipe 7 whereby the pipe is forcibly cooled. The difference in thermal expansion between the pipe 7 and the refractories 8 is thus decreased to prevent the temp. rise of the lance 3 and the generation of crack and peeling in the refractories 8 is prevented, whereby the service life of the lance is extended.

Abstract: PROBLEM TO BE SOLVED: To alleviate and block the current concentration in a multilayered wiring structure, by connecting the regions where electric connection is performed with one or a plurality of interlayer connecting conductors, and arranging the interlayer connecting conductors in the asymmetric pattern at the side of the intersecting interior angle of the conductor-layers of a plurality of overlapped region of the second conductor layers larger than the first conductor width. SOLUTION: Lower wirings (dotted lines) 1 and upper wirings (full lines) 2 are connected by interlayer connecting wirings, so-called via wirings 3. A region 4, which is extruded in the inside, is present in the intersecting region of these upper and lower wirings. A part of the region becomes a region 5, which is recessed to the inside, between the upper and lower wirings 1 and 2. Furthermore, in the intersecting region of the upper and lower wirings, the positions of the via wirings 3, which are alinged on the diagonal line toward the outside B from the inside A, are located to the inside as a whole. Some of the plurality of via wirings 3 are located at the inner side of the intersection than the region, wherein the upper and lower wirings are externally inserted on the straight line.  Since the recessed region 5 in the wiring hinders the current, the current does not flow only on the via wiring 3 located at the innermost side.

Title: Method and apparatus for preventing adhesion of incinerated ash to inner wall of powder incinerator
Inventor: KATAOKA FUKUTARO
IPC: F23G5/00
Filed: 1988-01-29
Abstract: PURPOSE:To make it possible to clean a furnace wall and to control the combustion temperature in an incinerator through using a reducing gas, by mixing particles of completely incinerated ashes into a reducing gas for combustion and temperature control, thereby supplying the incinerated ash particles into an excessively high temperature combustion zone in the main body of the incinerator. CONSTITUTION:Incinerated ashes not smaller than a predetermined size are supplied through a chute 16 into a precipitation tank 20. On the other hand, when an excessively high temperature combustion zone is generated in the main body 1 of an incinerator, at least one of flow control valves 271-274 corresponding to the zone is opened, and a reducing gas is blown into the main body 1 through a passage 24 by a blower 33. The reducing gas is passed through the precipitation tank 20, which is disposed between reducing gas passages 32 and 24. Therefore, incinerated ash particles for cleaning which are not smaller than a predetermined size and are capable of being blown by the blast pressure are mixed into and conveyed by the reducing gas, and are blown into the main body 1 in a swirl flow. The incinerated ash particles collide against a powder being about to adhere to the inner surface of the furnace wall in a molten or semi-molten state, and separate the power from the inner surface. Simultaneously, the combustion temperature is restrained from rising, by the reducing gas blown in with a low oxygen concentration.

CONSTITUTION:At the time of writing, a comparison part 22 detects whether the time slot number of a multidrop line designation part 21 is coincident with the time slot number from a write order set part 17 or not. At the time of reading, it is detected whether the time slot number of the multidrop line designation part 21 is coincident with the time slot number from a read order set part 18 or not. At the time of writing and reading, when the both time slot numbers are coincident, the line exchange is executed in a multidrop memory 23 and the data on an input highway 11 are transferred to an output highway 13. When the time slot numbers are noncoincident, the line exchange is executed in a channel memory 12 and the data are transferred. Thus, the externally attached multidrop device is eliminated.

Title: Recording member detector
Inventor: OGATA YUKIHIKO
IPC: H04N1/23
Filed: 1981-02-13
Abstract: PURPOSE:To load recording paper correctly and to prevent malfunctio such as upside back loading, by discriminating the detection of a recording paper through the resistance value. CONSTITUTION:When a recording paper 1 is present on an isolator 12, a resistance value specific to a recording paper is present between two detection terminals 13 and 14 contacted with a recording plane. A voltage of a DC power supply 15 is divided with the resistance value between the terminals 13 and 14 and a resistor RS and a voltage VS specific to the recording paper 1 is generated. On the other hand, a voltage of the power supply 15 is divided with resistors R1, R2 and a reference voltage VR is generated. If the recording paper 1 is present so that the recording surface is in contact with the terminals 13 and 14, the voltage VS is greater than the VR, a voltage comparator 16 outputs a recording paper detecting signal (a). If the recording paper 1 is absent, or if the recording surface is not loaded in contact with the terminals 13 and 14, the resistance value between the terminals 13 and 14 is infinite. Thus, the voltage VS is smaller  than the VR and the signal (a) is not outputted from the comparator 16.

IPC: G03B13/06
Filed: 1989-01-31
Abstract: PURPOSE:To make a finder and a strobe light emitting window larger while keeping a camera small-sized by using the finder window of a direct optical view finder also as the strobe light emitting window. CONSTITUTION:When a stroboscopic switch 6 is turned on, the charging of a strobe light emission circuit is started and a solenoid 12 becomes in an action- enabled state. When a release button 2 is depressed, a shutter is driven. At the same time, the solenoid 12 is excited, a plunger 11 is attracted and a stroboscopic device 7 rushes in the optical path of the finder 5, when the stroboscope is allowed to emit light. Thereafter, when the shutter is closed and the energizing of the solenoid 12 is stopped, the stroboscopic device 7 is pulled by a coil spring 8 to retreat to the outside of the optical path of the finder 5. Since the finder window is also used as the strobe light emitting window, the finder and the stroboscopic device can be made larger while keeping the camera compact.

Filed: 1981-02-12
Abstract: PURPOSE:To enable to prevent drop of efficiency due to heating of fluid on the fluid inlet side, by closing an oil passage between a slide valve and a rotor casing at an intermediate portion thereof by shifting the slide valve. CONSTITUTION:Oil introduced from an inlet 71 is passed through an oil groove 72 and ejected from an injection port 75 into a work space formed on the outside of a male rotor 4 and a female rotor 5. Here, arrangement is such that the injection port 75 can be shifted by moving a slide valve 32 to the right. Therefore, in case of operating a compressor under partial load, the injection port 75 is shifted to a proper position where it is not communicated to a suction space. In this state, oil is carried through an oil passage 76 via oil grooves 72, 73, 74 and supplied into the work space on the outside of the male and female rotors 4, 5 at a position displaced one pitch to the outlet side from the end wall of the suction side. Therefore, leakage of lubricating oil can be prevented and fluid at the suction side is not heated by high-temperature lubricating oil, so that it is enabled to prevent the drop of the efficiency of the screw compressor.
