Title: Hydrogen peroxide carrier and method for purifying water using the carrier
Inventor: JODAI TOSHIHIKO
IPC: C02F1/50
Filed: 1989-09-26
Abstract: PURPOSE:To obtain the hydrogen peroxide carrier with the duration of reaction increased and capable of sufficiently diffusing in water and efficiently purifying water by impregnating a porous granular body contg. a trace of iron (except hydrated calcium silicate) with hydrogen peroxide. CONSTITUTION:The porous granular body contg. a trace of iron (except the porous granular body of hydrated calcium silicate) is impregnated with hydrogen peroxide. The hydrogen peroxide is absorbed in the void of the body at this time. When the body is placed in water contaminated with the red tide, etc., hydrogen peroxide is gradually liberated and allowed to react with the plankton and suspended dust in the water to generate active oxygen, and the carrier is floated or sunk as the oxygen is attached to or detached from the carrier. Meanwhile, a part of the hydrogen peroxide generates OH radical by the Fenton reaction with iron ion to increase the oxidizing force. Consequently, the duration of reaction is increased, hydrogen peroxide is sufficiently diffused, and phytoplankton, etc., are efficiently exterminated.

Title: Optical modulator
Inventor: SAKAKI HIROYUKI
IPC: G02F1/017
Filed: 1988-10-05
Abstract: PURPOSE:To obtain a high on/off ratio even under a high electric field by forming the well layers of semiconductor quantum well structures of a non- mixed crystal semiconductor and specifying the compsn. of the semiconductor having a wide band gap to be included in the semiconductor which is an insertion barrier layer to >=0.5. CONSTITUTION:The optical modulator consists of an n<+>-GaAs substrate 11, an n<+>-GaAs buffer layer 12, an n<+>-AlGaAs layer 132, 30 periods of the semiconductoer quantum well structures (PIQW) 14, a GaAs cap layer 15, a Schottky electrode 161, an ohomic electrode 162. The compsn. of the Al in the layer 132 is 0.5. The basic wave function 21 of electrons and the wave function 22 of the base state of holes are superposed but the wave function 21 and the wave function 23 of the excitation state of holes are not superposed. Absorption is, therefore, generated by the energy difference E0 between the base states of the electrons and the holes. The wave function 21 shifts to the well 1410 on the low energy side when the electric field is impressed to the modulator. Since the AlAs insertion barrier layer 1420 is high, the absorption by the overlap between the base states is weakened and the change in the absorption at E0 increases.

Title: Switched capacitor integrating circuit
Inventor: MASUDA EIJI
IPC: H03H19/00
Filed: 1983-12-27
Abstract: PURPOSE:To compensate assuredly offset voltage of a operation amplifier by operating the second switching circuit which synchronizes to the first switching circuit and is driven by switching. CONSTITUTION:When an input signal voltage VIN is impressed upon an input terminal 31, the offset voltage VOS of an operation amplifier 37 is outputted to an output terminal 38 when a clock signal phi2 is in the H level period. Then, an input signal voltage VIN is impressed upon the side which is connected with a switched capacitor circuit 36 when a clock signal phi1 is in the H level period. However, as mentioned above a condenser C12 holds the offset voltage VOS of the operation amplifier 37 as it has the charged voltage. Therefore, the voltages VIN - VOS are impressed upon the inversion input end (-) of the operation amplifier 37 after all, and the normal integration operation is executed.

Title: Method of driving ferrodielectric capacitor
Inventor: ESU SHIEFUIIRUDO IITON JIYUNIA
IPC: H01L29/792
Filed: 1988-10-05
Abstract: PURPOSE: To maintain a polarization state after this state is set by an impressed voltage by coupling writing pulses to one end of a capacitor and opening the electrode before changing the potential of the writing pulses. CONSTITUTION: This capacitor 20 is used to store data by using the polarization state of a ferroelectric material. The open circuit state is, however, deliberately induced in such a manner that the pulses of certain long duration time are supplied from the visual point of the ferroelectric material after the supply of the writing pulses is started by capacitor plates 20a, 20b. More preferably, the gate electrode of a field effect transistor(FET) 26 is pulse driven to close the gate before the drop of a drain voltage down to 0 volt in such a manner that the ferroelectric capacitor 20 receives the writing pulses through the source and drain passages of the FET 20. As a result, the charges are moved through the ferroelectric material and the polarization state is stabilized.

Title: Improving method for resolution in laser beam deflection
Inventor: NAKAGAWA KIMIO
IPC: H01S3/101
Filed: 1985-11-07
Abstract: PURPOSE:To readily improve resolution by a simple optical system by repeatedly applying a laser beam deflected by a movable mirror to the same mirror to increase a deflecting angle. CONSTITUTION:A laser beam deflected by a movable mirror 4 is repeatedly applied to the mirror 4 to multiply the deflecting angle by the number of applications to substantially improve the resolution. When an optical system for multiplying the resolution having, for example, a stationary mirror 3 and cylindrical lenses 1, 2 is added to the normal mirror 4 to be operated, the applied laser beam 5 is repeatedly reciprocated between the mirrors 4 and 3 through the lenses 1, 2 to increase the deflecting angle by phi whenever the beam is applied to the mirror 4. Therefore, when the beam is applied three times to the mirror 4, the emitted beam obtains three times deflecting angle. Since the resolution of NRpi/4(phiD/lambda) (where lambda is the wavelength of the laser beam) of the case of only the movable mirror when the diameter of an incident beam 5 is D is proportional to the product of phiD, the resolution is improved to three times in this case.

Title: Terminal network controller
Inventor: YAMASHITA KUNIHIKO
IPC: H04M1/00
Filed: 1993-10-06
Abstract: PURPOSE:To obtain a terminal network controller which does not conduct a communication operation caused by insignificant outgoing by utilizing a speech path means and conducting communication caused by outgoing, only in the case a prescribed voltage is outputted from a line power source means. CONSTITUTION:This terminal network controller 1 is connected to a telephone line 5, and also, when a communication request by outgoing is generated from a terminal 4, a communication control means 10 drives a line power source means 11, and the line power source means 11 draws a current from the telephone line 5 and supplies electric power to a speech path means 9, etc. Subsequently, since it can be decided that the line power source means 11 supplies electric power, the communication control means 10 utilizes the speech path means 9 and conducts a communication operation by outgoing. In the case this controller is not connected to the telephone line 5, or if the telephone line 5 is disconnected, the line power source means 11 cannot supply electric power. Accordingly, the communication control means 10 does not conduct the communication operation caused by outgoing. In such a manner, by utilizing the line power source means 11, the communication operation caused by invalid outgoing can be eliminated.

Title: Digital control type temperature compensating quartz oscillator
Inventor: TAKEUCHI TAKASHI
IPC: H03H9/02
Filed: 1987-10-06
Abstract: PURPOSE:To reduce the FM noise by inserting a waveform converter to convert the waveform of the output of a decoder to a staircase wave, between the decoder and plural transistors(TRs) to control capacitors for temperature compensation. CONSTITUTION:When the output of a decoder 4 is inputted to a waveform converters 5, and the waveform converter 5 detects the rise or the fall of input to output a staircase waveform in a determined number N of steps at intervals of >10ms determined time which is not a problem for the FM noise. The output of this waveform converter 5 becomes a TR control signal 6 and is supplied to a TR 8 to control a capacitor 9. Since the TR control signal 6 is applied to the gate of the TR 8, the on-state resistance of the TR is changed, the capacitive component is also changed at the time of the change of the resistance with respect to the impedance for series connection between the capacitor and a resistance. Consequently, the oscillation frequency is changed at intervals of a determined time little by little when the on-state resistance of the TR is changed. Thus, the FM noise is reduced.
