Title: Power source
Inventor: KOYAMA OSAMU
IPC: H02M3/28
Filed: 1991-02-08
Abstract: PURPOSE:To rapidly restart a power source by switching on a driving transistor when a transistor across a restarted capacitor is interrupted to charge the capacitor by a DC input voltage if an oscillation is stopped, so that it becomes a predetermined voltage. CONSTITUTION:A partial voltage of an output of a feedback winding 21B of a switching transformer 21 is applied to a base of a transistor (RT) 10 for a restarting switch. A DC input voltage is divided and applied to a collector of the TR 10. A restarting capacitor (RC) 9 is connected between a collector and an emitter of the RT 10. A restarting resistor 8 is connected between the collector of the RT 10 and a base of a driving transistor (DT) 5. That is, when a circuit is normally operated, the RT 10 is switched on, so that no voltage is generated at the RC 9. When an oscillation is stopped, the RC 9 is charged, a microscopic current is supplied to the base of the transistor DT 5, and the oscillation is again started.

Title: Sine wave generating circuit
Inventor: OOISHI YASUNOBU
IPC: H03B28/00
Filed: 1984-02-02
Abstract: PURPOSE:To obtain a sine wave output having a reduced degree of waveform distortions by supplying the output frequency of a programmable frequency divider to an integration filter after switching said frequency. CONSTITUTION:The pulse train applied to a pulse train input terminal 21 is supplied to a programmable frequency divider 22, and the output of the divider 22 is supplied to a filter 23. While multiplexers 271-27N function as digital switches which set with switching the preset data of the divider 22 in response to the contents of a counter 26. Therefore the division ratio of the divider 22 is changed ever time the preset data is switched. Then the frequency of the output pulse is also changed. This switching cycle is equal to the cycle of a sine wave obtained by the filter 23. Thus the waveform distortions can be reduced for a sine wave output.

Title: Magnetic card
Inventor: YASUGATA KAZUHIRO
IPC: G06K19/00
Filed: 1988-01-28
Abstract: PURPOSE:To prevent recorded information from being erased by an external magnetic field by providing superconductors to cover both faces of a magnetic medium and rebounding the magnetic flux of the external magnetic field by the superconductors. CONSTITUTION:The front and rear faces of a magnetic film 12 with which writing and reading-out of information are carried out are covered by the superconductors 14, 16. The superconductors 14, 16 are formed of a yttrium oxide and become superconducting in liquid nitrogen. A magnetic card 10 constituted in such a manner exhibits a superconducting state when the superconductors 14, 16 are preserved in liquid nitrogen. The magnetic flux is, therefore, rebounded by the superconductors 14, 16 by the Meissner effect thereof and is prevented from intruding into the conductors 14, 16 even if the external magnetic field exists around the magnetic card. Since the external magnetic field does not act on the magnetic medium 12, the erasing or changing of the information recorded on the medium 12 is prevented.

Title: Method for treating waste water with clarification vessel of intermittent aeration type
Inventor: NAITO SHINJI
IPC: C02F3/30
Filed: 1992-02-03
Abstract: PURPOSE:To improve the reaction efficiency in a denitrification process to obtain high quality treated water by passing water through precipitated sludge while passing the sludge through the supernatant by transferring the precipitated sludge and water from upstream cells to downstream cells while transferring the precipitated sludge and water from the downstream end cell to the upstream end chamber. CONSTITUTION:A clarification vessel 1 is divided into cells 8A-8E. In a denitrification process, precipitated sludge and water are transferred from upstream cells to downstream cells while the precipitated sludge and water are transferred from a downstream end cell 8E to an upstream end cell 8A. Since water transferred is passed through the precipitated sludge while the sludge transferred is passed through the supernatant in each cell during the denitrification, the contact efficiency between original water and the precipitated sludge can be effected as is the case with the mechanical agitation of the clarification vessel. In this way, organic substances contained in the original water are sufficiently supplied to the sludge so that the denitrification reaction is carried out efficiently.
