Title: Method for controlling pwm inverter
Inventor: YASUDA TAKASHI
IPC: H02M7/483
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To suppress the voltage change, when the pulse mode is switched to a one-pule mode from a synchronous three-pulse mode by expanding the upper limit of the output voltage control range in the synchronous three-pulse mode. SOLUTION: Phases α-γ in an ideal state, where the minimum pulse width θmin is set at '0', are read out from a voltage pulse changing phase table 2, based on a voltage command E*. A minimum pulse width computing means 3 converts the minimum pulse width θmin into the scale of the basic wave phase of an output voltage, by performing calculation from a basic frequency command Fi * and prescribed minimum pulse Tmin . A minimum pulse width checking/pulse changing-phase resetting means 4 compares the intervals among phases α*-γ* with the minimum pulse width θmin , and when the pulse width is narrower than the minimum pulse width θmin , the phases α-γ are reset. A voltage pulse pattern setting means 6 generates a voltage pulse pattern S, based on the phase θoutputted from an integrator 5 and reset phases α-γ.

Title: Production of oxide superconductor
Inventor: ISHIKAWA YUICHI
IPC: C01B13/14
Filed: 1988-06-22
Abstract: PURPOSE:To prevent generation of oxygen defect in a superconductor by the effect of oxygen generated by the thermal cracking of silver oxide by allowing silver oxide to be present in oxides of a superconducting material in a stage of heating the superconducting material. CONSTITUTION:In a heating stage (annealing, provisional calcination or calcination, sintering) for prepg. an oxide superconductor, silver oxide is cracked thermally by allowing silver oxide to be present in a predetermined mixture of oxides and heating said mixture. Since several stages of heating are necessary in a coprecipitation process or mixing process performed generally for the prepn. of an oxide superconductor, so the superconducting characteristics are degraded remarkably by the effect of oxygen defect. However, oxygen in a solid phase reaction system is held always in an excess amt. by the above- described method, so formation of a tetra phase exhibiting no superconducting characteristics is inhibited. A partial oxygen pressure in a reaction system can be increased in a silver sheathing method which is adopted as a general method for the prepn. of a superconducting wire, and generation of oxygen defect in a superconducting phase is inhibited also.

IPC: H03M11/08
Filed: 1986-06-30
Abstract: PURPOSE:To decrease the number of key switches and to attain the fast input of characters by operating the right and left switch groups with an independent operation or a simultaneous operation of right and left hands for input of the character groups of words/phrases set previously by the stenographic characters. CONSTITUTION:A character input device 1 contains an arithmetic memory means 4 which outputs the character symbols supplied with operation of a switch group 2 to a printer 3 after storage arithmetic. For input of characters five switches are selectively operated out of the left character input switches 11-15, the 1st left key switch 21 and the 2nd left key switch 23. At the same time, five switches are also selectively operated out of the right character input switches 16-20, the 1st right key switch 22 and the 2nd right key switch 24. In such a way, the number of key switches can be decreased and quick operations are secured with these switches since the fingers of both hands can be kept on each home position.

Title: Semiconductor ion sensor
Inventor: SHINOHARA ETSUO
IPC: G01N27/414
Filed: 1986-07-02
Abstract: PURPOSE:To facilitate the work of building a sensor body, by providing a window adapted to bring an aqueous solution to be measured into contact with an ion sensitive film to induce an interface potential generated at the window to a gate area. CONSTITUTION:A sensor and a collation electrode are combined to be immersed into an electrolytic solution to be measured. When a Ta2O5 layer 8 gets in contact direct with the electrolytic solution through a window 10, an interface potential is generated in the layer 8 corresponding to the activity of ion to be measured in the solution. The interface potential is induced to an Si3N4 layer 6 through a ground metal film 7. As the portion of the layer 6 corresponding to a gate area 4 reaches a potential equivalent to the interface potential, the dielectric constant of the area 4 varies with the interface potential. So, a specified voltage is applied between a source and a drain to obtain a current value corresponding to the activity of ions. Therefore, the setting of an appropriate size of the window 10 produces I>=SD current almost corresponding to the ion activity while the arrangement of the window 10 at a desired position facilitates manufacturing work with a lower dimensional accuracy.

Abstract: PURPOSE:To recover H2S as elemental sulfur at low cost as compared to a conventional method such as caustic soda method while repeatedly using inexpensive ferrous sulfate, by oxidizing ferrous sulfate to ferric sulfate by using iron oxidizing bacteria to use the same in absorbing H2S. CONSTITUTION:A small amount of seed culture of iron oxidizing bacteria is added to a solution containing ferrous sulfate and acidified with sulfuric acid introduced into an oxidizing tank and air is blown into said solution to propagate the bacteria and, at the same time, ferrous sulfate is oxidized to ferric sulfate. In the next step, this ferric sulfate solution is used as the absorbing liquid to absorb H2S in H2S-contg. gas and the treated gas is exhausted. A foaming agent is added to the solution contg. fine colloidal elemental sulfur after absorptive reaction to flocculate colloidal sulfur and, after a cation collector or the like is added under stirring, the treated liquid is applied to a floatation machine to perform floatation separation to remove sulfur. The clear floatation tail liquid is a ferrous sulfate solution which is, in turn, returned to a bacterial oxidizing tank and ferrous sulfate is again oxidized to ferric sulfate to be used in H2S absorption.
