Title: Voltage controller for energy storage system of superconducting magnet
Inventor: HIRANO MASARU
IPC: G05F1/56
Filed: 1987-09-03
Abstract: PURPOSE:To control effective power at high speed with high accuracy by installing a voltage controller outputting an effective-voltage operation signal controlling the deviation of an effective-voltage reference signal and a voltage feedback signal so as to be brought to zero or kept constant. CONSTITUTION:A voltage controller 11c outputs an effective-power operation signal Vp controlling the deviation of an effective-voltage reference signal Vdr input from a divider 11a and a voltage feedback signal Vf acquired by compensating a DC voltage signal Vd by a voltage drop section by commutating reactance so as to be brought to zero or kept constant. A reactive-voltage operation signal Vq related to a value obtained by dividing quantity as the reference of reactive power by DC currents is set by a reactive-voltage reference generator 12. A firing angle alpha is arithmetically operated from the rate of effective and reactive voltage operation signals Vp and Vq and the ratio of the effective voltage to non-load maximum DC voltage in a firing- angle computing element 7A. A phase controller 8A transmits ignition pulses corresponding to the phase of the firing angle alpha over a power converter 2. Effective power can be controlled univocally by the control of DC voltage determined by the firing angle alpha. Accordingly, effective power can be controlled at high speed with high accuracy by voltage control using the DC voltage.

Abstract: PURPOSE: To make the distributing state of an organometal gas on a susceptor uniform by introducing the organometal gas to a reaction chamber after electrostatically charging the gas and controlling the flow of the gas toward the top of the susceptor in the chamber by utilizing an electric field and/or magnetic field. CONSTITUTION: An organometal gas vaporized along an organometal gas introducing pipe 4 is introduced to a reaction chamber 2 after it is electrostatically charged with plus charges and accelerated when it passes through a screen grid 7. When the mesh of the grid 7 is made closer as going toward the outer periphery of the grid 7, with the mesh at the central part in the top view being the coarsest, the distributing state of the charged organometal gas after the gas passes through the grid 7 can be made uniform to some extent. The charged gas near the outer periphery of the susceptor is pushed toward the central section side by the resiliency from a suppressor grid 8 as shown by the arrow (a) and reaches the surface of each sapphire substrate 11 on the susceptor 6. As a result, a uniform distributing state is obtained as shown by the dotted line S2 .

Filed: 1997-08-15
Abstract: PROBLEM TO BE SOLVED: To test a semiconductor memory without directly and externally outputting each output data by selecting either operation mode of the first test mode of normal mode and semiconductor memory function test and the second test mode of coincidence detection and circuit failure detection. SOLUTION: If at least one of NMOSs 28, 30, 32, 34 of a result outputting circuit 16 is on, the coincidence detecting line 35 is discharged through NMOSs 28, 30, 32, 34 and the buffer 36 outputting signal TDO becomes 0. And only when NMOSs are all off, a coincidence detecting line 35 is not discharged but the output signal TDO becomes 1. When, for example, the EOR gate 20 output signals of the semiconductor memory 12 test circuit and the coincidence detecting circuit 14 are stuck to 1, the NMOS 28 of the result outputting circuit 16 is firmly on. Accordingly at the time of semiconductor memory 12 function test in the first test mode, the coincidence detecting line 35 is discharged through NMOS 28 and the output signal TDO becomes 0 to detect the trouble of the EOR GATE 28.

Title: Recovery of gallium from dust in aluminum electrolytic furnace
Inventor: IKEDA HIDETSUGU
IPC: C01G15/00
Filed: 1982-12-17
Abstract: PURPOSE:The dust from aluminum electrolytic furnaces is subjected to floatation to separate and concentrate gallium and the resultant froth is roasted and leached with an acid at elevated temperature, then the gallium is precipitated in the form of its hydroxide, whereby gallium is simply and inexpensively recovered in high efficiency. CONSTITUTION:The dust from Al electrolytic furnaces containing a relatively high concentration of Ga is made into a slurry of 50-200g/l concentration and subjected to floatation together with a decarburizing agent and a foaming agent to obtain the froth containing Ga concentrated doble, then the resultant froth is roasted at 500-800 deg.C. Thus, the concentration of Ga is doubled further and the product is subjected to leaching out with a mineral acid such as sulfuric, hydrochloric and nitric acid at high temperature of 80-100 deg.C to obtain a slurry. The slurry is combined with a reducing agent such as iron dust to reduce Fe<+++> to Fe<++>, then the slurry is filtered. The resultant filtrate is combined with an alkali to adjust its pH to 4-5 to convert the gallium component selectively into its hydroxide to precipitate. The resultant hydroxide is about 20 times the concentration of Ga in the roasted product and recovered for the production of metallic Ga.

Title: Hot water boiler
Inventor: TAKAYAMA SHOICHI
IPC: F24H1/18
Filed: 1987-09-03
Abstract: PURPOSE:To uniformize the temperature of hot water in a hot water reserving tank, thereby reduce the number of ON-OFF shifts of a burner and enhance durability of a controller, by providing a fan in the hot water reserving tank, and rotating the fan to circulate the hot water in the tank when the temperature difference in the hot water in the tank reaches or exceeds a predetermined value. CONSTITUTION:When the temperature difference between an upper part and a lower part of hot water contained in a hot water reserving tank 11 is increased, outputs from thermistors 15, 16 are varied, so that an output from an operational amplifier 19 is increased accordingly. The output voltage from the amplifier 19 is inputted to the plus (+) side of a comparator 21 through a differentiating circuit 20 provided with a discharge circuit. As the temperature difference detected through the thermistors 15, 16 is increased, the output voltage from the amplifier comes to exceed a reference potential, and the differentiating circuit 20 so functions that the voltage portion in excess of the reference potential is outputted as a pulsed voltage from the comparator 21. As a result, a transistor 22 is turned ON to make a thyristor conduct, whereby a motor 17a for a fan 17 is rotated to uniformize the temperature in the tank 3, so that the temperature of the hot water fed out through a hot water supplying port 14 is stabilized.
