Title: Dispersant for gypsum
Inventor: KAWAMURA MASANOBU
IPC: C09K23/52
Filed: 1993-01-08
Abstract: PURPOSE:To make it possible to have excellent dispersibility and obtain sufficient fluidity even if mixed water amount is reduced by limiting a molecular weight distribution of a formaldehyde condensate of a bisphenol and aminobenzenesulfonic acid in a dispersant consisting essentially of the formaldehyde condensate. CONSTITUTION:This dispersant for gypsum has the above-mentioned main components and the condensate has <=30000 weight average molecular weight and contain <=40wt.% condensate having <=2000 molecular weight. Since this dispersant has extremely excellent dispersibility even in the case of short stirring and mixing time of gypsum, water and the dispersant, compared with well- known dispersant, sufficient fluidity is obtained even if mixed water amount is reduced and productivity of gypsum composition can be improved. The molar ratio (A:B) of a bisphenol (mol number: A) to aminobenzene sulfonic acid (mol number: B) is preferably (0.8-1.4):1.0 and as the bisphenol, compounds expressed by the general formula [X is CH2, C(CH3)2 or SO2] or their isomers are preferably used.

Abstract: PURPOSE:To improve a core reactivity and to enable an improvement of fuel economy, by inserting reactor control rods into a central and a peripheral regions of the reactor core at a beginning of an operation cycle in advance and withdrawing the reactor control rods at the peripheral region before an end of a beginning stage of the operation cycle which is less than around 500 Mwd/st of a fuel burn-up. CONSTITUTION:As shown in the figure (a), for a central region of a reactor core 1 loaded with fuels which do not require a shakedown operation, 9 reactor control rods are inserted upto the axial position (POS) 14 and for the outer most part of a peripheral region of the reactor core, 8 reactor control rods are inserted upto the position of POS 36. For reference, POSO shows a fully inserted core. Thereafter, until an end of a beginning stage of an operation cycle with around 500Mwd/st of fuel burn-up, shallowly inserted control rods at the peripheral region are withdrawn, as shown in the figure (b). And then between the operation cycle of 500-9,000Mwd/st burn-up, 5 of 9 deeply inserted control rods are withdrawn. Finally, between the operation cycle of 9,000-10,000 Mwd/st, the remaining control rods are withdrawn. In this final condition, the reactor is operated during the operation cycle 10,000-10,500Mwd/st burn-up.

Title: Electric cooker
Inventor: OKABE YOSHIYUKI
IPC: F24C7/02
Filed: 1984-02-03
Abstract: PURPOSE:To obtain uniform scorched color of bread regardless of the number of pieces of bread, by setting the scorching time for bread by the opening or closing state of electrical contact points of a sensor, which senses whether a material to be cooked is laid on a rack, and of which electrical contact points are opened and closed by a sensing lever which touches a material to be cooked, in an electric cooker such as an oven toaster. CONSTITUTION:For example, when two pieces of bread 8 are put on a wire net rack 3, the bread 8 actuates a sensing lever 4, which is moved down. Interlocked with the closing action of a door, the rack 3 is moved into a heating chamber. The lowered free end of a sensing lever 4 touches the tip of the lever 6 of a sensing switch 5, to close its contact points. When toasting operation is started in this state, a controller senses the closed states of contact points, and the time to toast two pieces of bread is set in an electronic timer 7. When one piece of bread is toastes, a bread 8 is to be placed on the side of a rack where the lever 4 is not assembled in, so that the time to toast one piece of bread can be set in a toaster, with the switch 5 remains open. In such a manner, the same brown scorched color can be put on bread regardless of the number of pieces of bread to be toasted.

Title: Semiconductor circuit
Inventor: SUZUKI KOUICHI
IPC: H01L21/337
Filed: 1979-02-20
Abstract: PURPOSE: To improve the linearity of variable resistance in a wide range of voltage, by connecting diodes in series with each other between the gates of two junction FET's different in electroconductive polarity from each other.  
     CONSTITUTION: An n-channel source is connected to the p-channel drain of two junction FET's different in electroconductive polarity from each other. An n-type diode is coupled to the n-channel gate of the FET's and a p-type diode is coupled to the p-channel gate of the FET's to interrupt the forward currents of the gates. As a result, the forward currents of the pn-junctions of the gates can be interrupted even if a voltage Vcc rises. Thus, the linearity of variable resistance is improved.

The voltage between both ends N, M of the resistance 9 is amplified by a low gain amplifier 10 and outputted to a terminal 11. The current that flows in the coil 5 flows in the direction which generated magnetic flux cancels magnetic flux generated by the coil 1. The two magnetic fluxes balances automatically, the the current in the coil 5 is proportionate to the current of the coil 1. Signals from the terminal 11 are outputted at a high speed and at a high response speed.

Filed: 1985-02-05
Abstract: PURPOSE:To compensate the angle of divergence of a laser beam through simple operation by composing a laser beam converting device of a conic reflecting mirror, a concave annular reflecting mirror, and an annular reflecting mirror for guiding out a laser beam. CONSTITUTION:The converting device consists of the conic reflecting mirror 8 which diverges like an unfolded for a ring-shaped parallel incident laser beam 1 and the concave annular reflecting mirror 10 which reflects the diverged reflected laser beam from the conic reflecting mirror 8 toward the annular laser beam guiding-out reflecting mirror 12 which is provided nearby and concentrically with the conic reflecting mirror 8 as the center. Consequently, the angle of divergence of the laser beam 7 is compensated only by varying the distance L between the concave annular reflecting mirror 10 and conic reflecting mirror 8. Namely, the internal diameter of the laser beam is varied, not to mention the external diameter and the value M defined by the ratio of the internal and external diameters is converted freely to easily generate the laser beam which meet various requirements of the laser beam.

Abstract: PURPOSE:To convert waste to a reduced amount of a stable solidified body by reducing the final amount of waste, by treating a concn. chemical decontamination waste liquid by known unit operation and keeping a greater part of radioactivity as electroplated metal waste. CONSTITUTION:The waste liquid obtained by the chemical decontamination of machinery piping 1 to be decontaminated is discharged to a makeup tank 2 and supplied to a reverse osmosis membrane (RO) separator 3 by a high pressure pump 11 to be concentrated up to 15%. A part of the conc. waste liquid is sent to a digester 4, and hydrogen peroxide and sulfuric acid are added to the digester 4 to decompose org. acid and a chelate agent. When a pH meter or TOC meter detects that an org. substance is decomposed to predetermined concn. or less, the waste liquid is sent to an electrodeposition tank 5 and a DC power supply 9 is applied to perform electrodeposition. The obtained electrodeposition substance is preserved in a shield cask 7. The waste liquid after electrodeposition is transferred to a neutralizing tank 6 to be neutralized and subsequently discharged to a waste treatment system. By this method, the term of works in decontamination work can be shortened and the exposure at the time of the treatment of waste can be reduced. Further, the final amount of waste can be also reduced.
