Title: Supporting method of diaphragm for underwater transmitter
Inventor: KOTANINO KIYOSHI
IPC: H04R7/20
Filed: 1981-09-24
Abstract: PURPOSE:To reduce the supporting stiffness, to increase the oscillation amplitude and to attain low frequency transmission, by interposing a magnetic fluid at the intermediate part of a support frame and floating a diaphragm in it. CONSTITUTION:A plurality of permanent magnets 11 and 12 are used for the support of a diaphragm, the circumference of the diaphragm 1 is freely supported with a magnetic fluid 15 and a support frame 7. Further, a driving system consists of a magnetic circuit comprising a center pole 4, a permanent magnet 5 and a yoke 6, a bobbin 2 and a voice coil 3 wound on the bobbin. A signal current flows to the voice coil 3 and the diaphragm 1 is driven through the vibration of the coil. A magnetic fluid supporting the circumference of the diaphragm 1 is liquid, and even if excitation with large amplitude is repeated, no fatigue and damage is given to the material and long period of stability can be realized. Thus, since the resonance frequency of the small sized drive system can be lowered without increasing the diameter of the diaphragm, low frequency drive can be performed.

Title: Circulating type vacuum degassing method
Inventor: NOBEMOTO AKIRA
IPC: C21C7/10
Filed: 1979-11-20
Abstract: PURPOSE:To accelerate vacuum degassing treatment, such as decarburization reaction, by homonizing a molten steel in a ladle by forced mixing at the initial stage of the circulating vacuum degassing treatment that a molten steel having constant quality may be supplied to the vacuum degassing treatment tank always. CONSTITUTION:During an unstable period at the begining of vacuum degas treatment (RH treatment), namely at least 5-10min from the commencement of treatment, molten steel 6 contained in ladle 5 is agitated by a blown gas from plug 7 and density difference between upper and lower layers of molten steel is eliminated. As a result, the total processing time can be reduced. Moreover, when this gas blowing is performed at the time of alloy adding to RH treatment tank 1, the adding amount required for each time can be increased and adding time required can be reduced. The above-mentioned agitation can also be made by blowing a gas from pipe 8.

Abstract: PURPOSE:To prevent a film from entering between a magazine and the shaft of a film feeding roller by lifting one end of a guide together with a rotor which is rotatably provided on the coupling shaft of the film feeding roller along the coupling shaft as the magazine is inserted. CONSTITUTION:When the magazine 1 is inserted, the V-shaped part 11c of the guide 11 is pushed by the magazine 1 and moves in the right direction. When the guide 11 is pushed and butts on a fixing shaft 20, the guide bar 12 on the top end of the perpendicular part 11a of the guide 11 rotates a rotor B 17 against the energizing force of a spring 19, so that the perpendicular part 11a and the guide bar 12 lift. Then, when the magazine 1 is inserted into a prescribed position, the rotor 17 is reversely rotated by the elasticity of the spring 19, the guide 11 descends, and the space between the shaft of the film feeding roller and the magazine 1 is eliminated. When the shutter 21 of the magazine 1 opens, the V-shaped part 11c of the guide descends and loads the film 2 falling in the magazine 1 thereto.

IPC: G06F3/12
Filed: 1988-06-20
Abstract: PURPOSE:To eliminate an omission of printing when a printer is faulty, by a method wherein when any one of printers in a plurality can not execute printing, a print output is made collectively to another normal printer after its operation is ended. CONSTITUTION:Various signals detected at a detection end are converted into signals for measurement by a converter 2 and incorporated into a control computer from an input interface 3. At a time point when prescribed computation is executed and time comes according to a signal from a clock 6, the result of computation is sent to printers 9 and 10 through interfaces 7 and 8 and a print output is made sequentially. On the occasion, the result of computation is stored in a storage element 5 simultaneously. In the case when either of the printers 9 and 10 turns incapable of printing due to a fault or the like, it is registered as faulty. When no recovery is made from the fault of the like even after the completion of a series of operations, the print data in the storage element 5 are outputted for printing to the normal one of the printers 9 and 10.

Title: Refining method for stainless steel using semi-reduced chromium pellet
Inventor: KATAYAMA HIROYUKI
IPC: C21C5/52
Filed: 1978-12-07
Abstract: PURPOSE: To refine stainless steel at low cost, which is not saturated with carbon, in good yield of Cr, by charging an electric arc furnace with steel scrap at the bottom and peripheral wall, and by charging the furnace with semi-reduced Cr pellet, coke, and lime, then by melting these raw materials.  
     CONSTITUTION: Steel scrap 3 is charged to spread all over the bottom and the peripheral wall of an electric arc furnace 1, and coke 5, lime 6, and semi-reduced Cr pellet 7 are charged to the central space and is mixed suitably. Some scrap 4 is placed on the top of the pellet 7 and an electric circuit is formed between the scrap and the electrode 2. The raw materials are melted by energizing the circuit after the raw materials are charged, then the slagging and melting of the pellets 7, the reduction of Cr, Fe with coke 5, formation and settling of carbide are effected, and the scrap 3 begins to melt molten slag 9 floating on the molten steel 8, and residual coke 5 floats on the slag 9. Because the molten steel comes into contact with the coke 5 through slag 9, it is hardly saturated with C.

Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To provide stable performance at low costs by providing one transparent substrate and the other opposing substrate and forming one substrate to have a chevron portion and a nearly flat portion. SOLUTION: A resin 9 is formed by a metallic mold to be separated into a part 3 having a slope 4 and a flat part 8. The slope 4 is folded at a pitch of 20μm so as to prevent the uneven increase or decrease of a liquid crystal cell gap. The slope 4 is formed to be wedge-like and one dimensional and a peak 5 and a valley 6 are formed in a horizontal direction. An ITO film 7 as a transparent electrode is formed on the full surface of the resin 3. By injecting high molecular dispersion crystals between these substrates, a liquid crystal cell is completed. A light passed through a glass base board 1 and made incident vertically from the lower side is reflected by several percentages on a boundary surface between the resin 3 and the ITO 7.  In this case, since the angles of elevation θ1 and θ2 of the slope 4 are set to 10 degrees, a reflected light is reflected by being inclined by ±20 deg. in left and right directions according the inclination of each slope.
