Patent JP-S55120203-A (JP)
Title: Acoustic amplification output circuit
Inventor: KOJIMA SHINICHI
IPC: H03F1/00
Filed: 1979-03-09
Abstract: PURPOSE:To prevent a residual sound from being generated at the time when power is turned off, by rapidly discharging a ripple removal capacitor provided to an initial-stage amplifier circuit. CONSTITUTION:The output of an initial-stage amplifier circuit formed of transistors TRQ1 and Q2 is inputted to A-class large-amplitude amplifying TRQ4, whose output drives B-class PP output circuit 1. Here, TRQ7 is provided which has its emitter connected to the terminal of power-ripple removal capacitor C1 and its base applied with bias voltage Vb obtained by Zener diode Z and resistance R9. This bias voltage applies a reverse bias between the base and emitter of TRQ7. As a result, TRQ7 is rapidly turned on by detecting the lowering of power voltage Vcc after the power is cut off to discharge capacitor C1, thereby stopping the operation of the initial-stage circuit. Therefore, the generation of a residual sound can be prevented. Additionally, a hop sound can also be prevented.

Title: Waste water treating device
Inventor: SUMINO TATSUO
IPC: C02F3/08
Filed: 1990-02-07
Abstract: PURPOSE:To efficiently execute a biotreatment without leaking microorganisms into treated water and without providing ancillary equipment, such as sterilizing tank, by installing a UV sterilizing device in a treating tank in which inclusively immobilized microorganisms are packed. CONSTITUTION:The UV sterilizing device 2 is installed in the treating tank 1 in which the inclusively immobilized microorganisms are packed. The inclusively immobilized microorganisms are produced from an inclusively immobilizing material 7 (e.g. polyurethane pellet) having low UV transmissibility. Namely, the UV rays do not penetrate the inside of the immobilizing material and do not hinder the activity of the microorganisms. Since waste water can be sterilized while components, such as BOD and COD, are removed with high efficiency in the treating tank, bacteria do not intrude into the treated water. Since the ancillary equipment is not provided, the formation of the compact treating device is possible. Moreover, the included and immobilized microorganisms are sterilized on the pellet surfaces but the microorganisms interior thereof are activated and, therefore, the treating efficiency is improved.

Title: Method for desalinization of condensed water
Inventor: TSURUMI TAKESHI
IPC: C02F1/42
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To prolong a water-passing period of a NH4 type condensed water desalinization device while blockage for water passing is surely prevented by a method wherein the number of fine particles reaches the specific number of pieces by measuring the number of fine particles in desalinization treated water from a mixed bed column, back washing of the mixed bed column or regeneration of a resin is carried out. SOLUTION: When water passing treatment is carried out by arranging a plurality of mixed bed columns in parallel, the number of fine particles of treated water is measured per each mixed bed column by using a fine particle detection meter for which laser beams, ultrasonic, etc., are utilized. In the case where the number of fine particles per unit volume of the treated water reaches the specific number of particles by this measurement, the water passing is changed to another mixed bed column, and back washing of the mixed bed column or regeneration of the resin is carried out. Thereby, blockage for water passing and deterioration of the treated water are surely prevented, and an operation period of time as a NH4 type condensed water desalinization device can be prolonged to a maximum limit.

Title: Optical communication method and system difficult in tapping, optical transmitter and optical receiver used therefor
Inventor: NITTA ATSUSHI
IPC: H04B10/516
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To transmit an optical signal in a state hardly causing tapping on a transmission line by separating at least one modulated light capable of restoring a signal from mixed light by utilizing mode differences and restoring at least one modulated light signal capable of restoring a signal. SOLUTION: A receiving side returns received mixed light to two optical signals in linear polarization states by using a polarization converting means 3 and selects one polarization state with a polarization selecting means 4. Finally, an optical transmitter 5 converts this selected polarization information into an electric signal. Since the receiving side understands the relation of polarization conversion performed by a transmitting side in this way, it can detect a polarization signal corresponding to TE polarization (or TM polarization) of the transmitting side and can reproduce an electric signal. Thus, it is difficult for a person who does not know how to change the modes to perform tapping on a transmission line and only a receiving side knowing how to change them can demodulate the signal.
