Patent JP-S6217950-A (JP)
Title: Manufacture of porous lithium-lead alloy electrode
Inventor: KUBOTA TADASHI
IPC: H01M4/1395
Filed: 1985-07-16
Abstract: PURPOSE:To obtain a large specific surface by forming and burning porous powder which has been generated by adding lead powder, having proper particle size and of which surface has adsorbed moisture, in molten lithium in an atmosphere of inactive gas. CONSTITUTION:Lead powder which is to be alloyed with lithium consists of particles of diameters from 1-10mum and is left to stand in a high humidity to adsorb sufficient moisture on its surface. After melting lithium 2 in an electric furnace 1 in an inactive gas atmosphere, lead powder 3 with moisture adsorbed on it is added in the molten lithium gradually in small quantity at a time. By this, moisture adsorbed on the surface of lead powder reacts with lithium to generate lithium hydroxide. This reaction raises the temperature of the lithium and melts the lead to make lithium-lead alloy. Generated lithium hydroxide decomposes into lithium oxide and water, with a part of lithium-lead scattering in powdery form as water vapor spouts. Scattered powder is collected on a mesh 5 placed outside a crucible 4, and porous lithium-lead is formed on the surface of alloy in the crucible after it has cooled down.

IPC: C10B57/04
Filed: 1979-12-05
Abstract: PURPOSE: To obtain blast furnace coke in which the reactivity of the coke produced is easily controlled, by a method wherein regenerated coal in which the H/C mole ratio is adjusted to a value corresponding to the volatile matter of low-grade coal, is blended with the low-grade coal.  
     CONSTITUTION: In the production of blast furnace coke from low-grade coal by blending regenerated coal with the low-grade coal, regenerated coal in which the H/C mole ratio is adjusted to a value corresponding to the volatile matter of the low-grade coal, is used. The reactivity of the coke is greatly varied depending on the H/C mole ratio of each component of the regenerated coal. Even when low- grade coal having a high content of the volatile matter is used as the raw material, the coke having low reactivity can be obtd. by blending regenerated coal having a small H/C mole ratio, or the component of the regenerated coal or a mixt. thereof with the low-grade coal. In order to classify the regenerated coal into components having different H/C mole ratio, a method such as a solvent separation method, a centrifugation method, a filtration method or a gravity settling method can be used.

Title: Gas laser oscillator
Inventor: SUMINO TSUTOMU
IPC: H01S3/097
Filed: 1988-06-27
Abstract: PURPOSE:To stabilize output by eliminating effect of impulse wave produced during discharge without preventing flow of gas laser medium by using the impulse wave. CONSTITUTION:Gas laser medium contained within an airtight container 1 is fed from a side of an air duct 7a to a discharge space of a main discharge electrode through an air blower 9 and circulates. A protection plate 10 is supported by a shaft 11 adjacent to the main discharge electrode 5 inside the air duct 7a and installed to rotate freely. The protection plate 10 stops at a position II during and before/after main discharge, and impulse wave generated during discharge collides against the protection plate 10 and an action of forcing back the flow of gas laser medium is prevented. Moreover, the impulse wave reflects from a recessed section 12 and works to allow gas laser medium to flow readily to a side of the main discharge electrode, that is, to a downstream side. While the protection plate 10 remains at the position II, the gas laser medium passes through a bypass 30 formed by the protection plate 10 and an auxiliary air duct 17 and a through hole 13 which is shaped on the protection plate 10, and then fed to a discharge space of the main discharge electrode. Flow of gas laser demium is not prevented at all.

Abstract: PROBLEM TO BE SOLVED: To limit an over current to flow to an NPN transistor with high accuracy through a simple overcurrent limiter circuit without being affected by the temperature characteristics of circuit elements, in a current output circuit for outputting a current through the NPN transistor. SOLUTION: A 1st PNP transistor Tra for base current control is connected to an NPN transistor Tro for output, and a 2nd PNP transistor Trb consisting of a current mirror circuit is connected to this transistor Tra. Then, the current to flow to the transistor Trb is controlled into constant current 11 by a constant current circuit so that the base current of the transistor Tro can be controlled. Besides, a resistor Ro is provided between the emitters of transistors Tra and Trb and according to a voltage drop (I3.Ro) at this resistor Ro, the base current of the transistor Tro is reduced. As a result, when the constant current circuit having negative temperature characteristics is used, the output current I3 can be always limited to lower than the constant current.

Abstract: PURPOSE: To manufacture a carbon electrode which has high mechanical strength and from which carbon particles are prevented from falling off and the service frequencies of which can be improved by filling a graphite base material with a thermosetting resin composition contg. a surfactant and converting the resin composition into glassy carbon. CONSTITUTION: Fine powder such as powdery coke is kneaded with a binder such as pitch and the kneaded material is pulverized and formed, then, the formed body is fired and carbonized and graphitized to obtain a graphite base material. The graphite base material thus obtained is filled with a thermosetting resin composition contg. a surfactant, such as furan resin or phenolic resin composition by subjecting the material to immersion treatment in the thermosetting resin composition, or the like. As the surfactant, an alkyl sulfosuccinate or the like is appropriate and preferably used in an amount enough to provide an about 0.1 to 10wt.% content in the composition based on the weight of the thermosetting resin.  Then, the graphite base material is heated to about 120 to 160 deg.C to cure the resin and thereafter, fired and carbonized at about 800 to 1,500 deg.C in a nonoxidizing atmosphere and further, graphitized at about 2,300 to 3,000 deg.C to convert the resin into glassy carbon. Thus, the objective carbon electrode having an about 7 to 20% filling ratio of glassy carbon is manufactured.

Abstract: PURPOSE:To obtain an easy-to-see picture by decreasing the residual vibration of a belt drive system caused at tape intermittent running for slow motion picture reproduction to avoid position change of noise bar in the reproduced picture. CONSTITUTION:This methid is a so-called short control form where a motor 4 is stopped by applying a motor drive voltage V1 for a time T1 and short-circuiting a switch 8 and the application time T1 of the motor drive voltage V1 is set by a monostable multivibrator 14.
