Abstract: PURPOSE:To achieve continuously long period stable operation by providing a pressing means to press an auxiliary roller to compress, by means of its circumferential surface, a layer of raw material to be captured by a grinding roller against the upper surface of a rotary table under an optional, pressure. CONSTITUTION:A plurality of grinding rollers 4 are disposed rotatably on the upper surface of outer periphery of a rotary table 3A to grind raw material fed to the central region of the table 3A by applying a predetermined grinding pressure to the rollers 4 so that the raw material is compressed between the upper surface of the table 3A and the circumferential surfaces of the rollers 4. And, auxiliary rollers 20 are rotatably disposed over the outer periphery of the table 3A between the rollers 4 and 4 so that a layer of the raw material to be captured by the rollers 4 is compressed by the circumferential surfaces of the rollers 20. And, by means of a pressing means comprising an arm 21, hydraulic cylinder 22, gap adjuster 24, etc., the roller 20 is pressed against the upper surface of the table 3A under optional pressure. As a result, by changing pressing forces of the auxiliary roller, vibration values can be reduced, thereby long period stable operation can condinuously be performed, resulting in improved productivity.

Title: Control device of engine
Inventor: YAMAMOTO MASARU
IPC: F02D23/02
Filed: 1991-10-11
Abstract: PURPOSE:To properly correct an engine control value for which output of an intake temperature sensor is utilized by compensating influence of high heat generated in an engine. CONSTITUTION:A value for controlling a regulating valve 20 by which a bypass air amount bypassing a throttle valve 15, is regulated, is corrected according to an intake air temperature. When an engine is cold with its cooling water temperature low, the minimum opening degree of the throttle valve 15 is enlarged so as to increase an intake air amount. On the other hand, after warming up the engine, the minimum opening degree of the throttle valve 15 is closed fully so as to decrease the intake air amount. Thus the degree of an intake air temperature correction in relation to the regulating valve 20 is changed according to the magnitude of the intake air amount.

Filed: 1991-10-11
Abstract: PURPOSE:To effectively prevent transmission of vibration over a wide range by variably setting a spring constant and damping coefficient of a device by a compact structure without providing a valve unit or the like. CONSTITUTION:A rubber elastic material wall 1 is spread to open downward into an umbrella shape to support a vibrating unit to a top surface. A pair of spaces 11, 12 are formed in a wall adjacent to an internal surface in a position of diametric directional symmetry of the rubber elastic material wall 1 and sealed with electric viscous fluid to form acting chambers C, D. A fluid circulating path F2, in which an electric field forming electrode film is formed on a path wall, is provided by connecting the acting chambers C, D, and an acting subchamber E with a rubber film 4 serving as a chamber wall is provided to connect the fluid circulating path F2 to branch. When an electrode is electrified, an electric field is generated in the fluid circulating path F2 to make the electric viscous fluid difficult to circulate. When vibration is input, the electric viscous fluid in the acting chambers C, D is disabled from flowing into the acting subchamber E, and an expansion spring constant of the rubber elastic material wall 1 is substantially increased to generate a small device spring constant and a large device damping coefficient in a high frequency side.

Title: Method for oxidation of ammonium ion and organic carbon in waste water
Inventor: KAARU GERUHARUTO BAUA
IPC: C02F11/08
Filed: 1993-11-24
Abstract: Oxidation of ammonium ions and organic carbon in ammonium-ion-containing and organic carbon-containing waste waters (effluents) by nitric acid at 100 to 350@C, in that the molar ratio of organic carbon to ammonium nitrogen is established at a range of 0.3:1 to 4:1 by addition of organic carbon or ammonium nitrogen. In a preferred embodiment which is reproduced by way of example in the figure, the waste water, which can be enriched, depending on the TOC content, with organic carbon, is transported via the feedline (1), possibly from an intermediate tank (2), by a pump (3) through a heat exchanger (4) in which it is preheated to, for example, 270@C. The preheated waste water is then heated by direct feed of 100 bar high-pressure steam via feedline (5) or by indirect heating to 290@C. After establishing the nitric acid concentration necessary for the ammonium degradation, e.g. via a feedline (6) in the waste water at 290@C, this is conveyed through a reactor (7) without back-mixing (e.g. a tubular reactor having internals and which is clad with titanium). After a residence time of, for example, 5 to 10 min, the reaction solution is cooled in counter-current with the feed and is depressurised in a separator (8). The waste water is removed via a line (9), via an intermediate tank (10) and a heat exchanger (11). <IMAGE>

Title: High withstand voltage semiconductor element
Inventor: NAKAGAWA AKIO
IPC: H01L21/336
Filed: 1987-11-20
Abstract: PURPOSE:To obtain sufficient high withstand voltage characteristics even through a first semiconductor layer is a thin one by a method wherein a fifth semiconductor layer having a low-impurity concentration is provided on a part adjacent to an insulator film under the bottom part of an element and part of an inverse bias applying voltage to the element is borne by a dielectric isolation film by a third semiconductor layer. CONSTITUTION:When a reverse bias is applied between first electrodes 11 and a second electrode 12, a depletion layer first spreads from an n<+> layer 6 in the center of the surface of an element into a high-resistance Si layer 4 in the longitudinal direction. If the thickness of the layer 4 and the impurity concentration of a p<-> layer 10 are each ready-set at a proper value, the largest electric field of the layer 4 is obtained at a value or less, at which an avalanche breakdown is generated, even though the layer 4 is depleted completely and the layer 10 under the bottom part of the layer 4 is depleted soon. If the layer 10 is depleted, the potentials of the electrodes 11 do not transmit up to right under the electrode 12. That is, a potential difference is generated in the depleted layer 10 in the lateral direction, the voltages between the electrodes 11 and 12 is finally divided into two components, one in the thickness direction of the layer 4 and one in the lateral direction of the layer 10, and high withstand voltage characteristics are shown even though the layer 4 is not thick.

Abstract: PURPOSE: To make it possible to measure with low cost by providing a measuring tank at the passing position of a sensor beam injecting specimen, subjecting it to sleeve action several times, and adopting an electric resistance value measuring method and an optical analyzing method of absorbing beam. CONSTITUTION: Liquid containing white blood corpuscles to be analyzed is poured from a duct 20, and fed to an inner chamber 18 via an orifice 21.

Further, the liquid preloaded from a duct 14 is poured, second sleeve action is conducted, and directed toward the inside of an annular chamber 13. In the case of passing the tank 5, it is optically measured by the beam 24. On the other hand, a resistance value measurement is conducted while the liquid passes the orifice 12 by applying a current to the two electrodes provided at both ends of the orifice 12, and volume is measured. An optical white blood corpuscle absorbing capacity measurement is conducted by the beam 24 passing the tank 5.  Thus, the measured values are computer processed, and the number of the white blood corpulcles is measured.
