Title: Clock oscillation circuit and clock extraction circuit
Inventor: TAYA TAKASHI
IPC: H04L7/033
Filed: 1992-02-10
Abstract: PURPOSE:To output a clock signal whose phase is synchronized with that of an input signal for oscillation phase control that is inputted by controlling a self-running oscillation phase corresponding to the input signal for oscillation phase control. CONSTITUTION:An emitter-coupled multivibrator circuit 11 performs self-running oscillation simultaneously with the supply of a power source. Meanwhile, a driver circuit 10 fetches a pulse signal for oscillation phase control, and detects whether or not it exceeds a threshold value, and such detection signal is supplied to one terminal of a timing capacitor C1 via a diode D3, and when it is judged that it exceeds the threshold value, the detection signal is used for control to lead or lag the oscillation phase, and when it is less than the threshold value. no change control of the self-running oscillation phase is performed. In such a way, the clock signal can be outputted by performing the self-running oscillation simultaneously with the supply of the power source, and also. the self- running oscillation phase can be controlled corresponding to, for example, a pulse rise or fall timing.

Title: Method of adding binder to raw kneaded material for briquet
Inventor: NISHIDA SHINICHIROU
IPC: C10L5/22
Filed: 1982-02-16
Abstract: PURPOSE:To enable a binder to fully exhibit its extending effect in a simple device without causing heat loss as in conventional processes, by directly adding a preliminarily emulsified and foamed binder to raw pulverized coal in a kneader. CONSTITUTION:A binder is pumped in from an inlet 2 and vapor is pumped in from an inlet 3 through a nozzle 4. A combined flow of the separately introduced binder and vapor is divided, reverted and rotated in a short period time by means of elements 5 in a static internal mixer 1 in a right-turn, left-turn, bisecting or quadrisecting manner to undergo radial mixing. Thus the binder is completely emulsified and foamed when it reaches a mixer nozzle 6. The preliminary emulsification and foaming of the binder improves its extendability, enables the binder to be directed sprayed into a kneader 7, and allows satisfactory  extension and coating of the raw pulverized coal in a short residence time with  the aid of the kneader 7. Thus a good starting material for briquet can be obtained.

Title: Method of treating leakage of battery
Inventor: MIYAZAWA KANAME
IPC: H01M50/186
Filed: 1982-02-18
Abstract: PURPOSE:To remove the effect of the leakage of an alkaline storage battery on a mechanical body by neutralizing it by the ion exchange method. CONSTITUTION:The places where treatment is to be applied are the gap between a negative electrode and a packing section and a peripheral section, that is, shaded portions 1. These places are bonded and coated by dispersing the H-type ion exchange resin into water soluble polymer. The water soluble polymer shall be such one as polyvinyl alcohol, polyvinyl pyrrolidone, cellulose, etc. and any mixture containing proper quantities of these polymers can also be used. The reason why the water soluble polymers are used is to effectively improve the ion exchange reaction between the leaked liquid that is an alkali and the H- type ion exchange resin. Both strong and weak acid exchange resins can be used as the H-type ion exchange resin and their particle diameter should be preferably about 0.5-500mu. Since the surface and contact areas are increased as the particles become finer, the efficiency of ion exchange is improved more as the particle size decreases.

Title: Machining method for three-dimensional curved surface shape
Inventor: MIZUNO RIE
IPC: G05B19/4093
Filed: 1992-02-12
Abstract: PURPOSE:To correct only a detected surface and to accurately machine the shape by detecting the presence of an overhang surface of a drawing before the CAM machining. CONSTITUTION:The type of a curved surface is decided 3 and a point on the surface is selected 4 by a method matching the type of the surface. Then, the normal line of the curved surface is calculated 5 for each of selected points, and the direction of the normal line is checked to decide whether the surface is an overhang surface or not 6. This decision is carried out based on the angle formed between the Z axis of a three-dimensional coordinate system and the normal line. This operation is carried out for every curved surface in a drawing. Thus an overhang surface is decided in the drawing and a prescribed shape is accurately machined with the previous correction of the relevant curved surface.
