Title: Current controller
Inventor: KIMURA MITSUTOSHI
IPC: H02M3/155
Filed: 1984-03-31
Abstract: PURPOSE:To improve economic value without heat loss, by a method wherein voltage between drain sources when a field effect transistor is ON is detected and the current quantity of the transistor is controlled according to the voltage. CONSTITUTION:A diode 3, a current-limiting coil 4, a condenser 5 and a load 6 are connected to the source 1 of power made into AC via a field effect transistor (Tr)2 of MOS type, and the current quantity is controlled. Then, voltage between drain sources when the Tr2 is ON is detected by a detection circuit 7. So far as the voltage detection circuit 7 is concerned, the collector of the Tr8 is connected to the drain of the Tr2 via a resistance 9 as shown in the figure. And so far as the Tr2 is concerned, the switching duty ratio is variably controlled according to the input voltage by the pulse width modulation (PWM) control circuit 15 in the control circuit 13. Thus, as the electric current ID sent to the Tr2 is increased, the voltage between drain sources gets higher and the output of an error amplifier 14 is increased and the Tr2 is PWM-controlled.

Title: Ofdm signal transmitter
Inventor: SATO KAZUMI
IPC: H04L27/26
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To reduce instantaneous maximum power of a time waveform of an orthogonal frequency division multiplexed(OFDM) signal. SOLUTION: A serial/parallel conversion section 2 provides the output of a complex information subcarrier signal to a fast inverse Fourier transform section 3, based on an information bit series. The transform section 3 applies fast inverse Fourier transform to a received subcarrier signal to obtain complex baseband time waveform with an OFDM symbol. A complex redundant subcarrier signal generating section 4 generates a complex redundant subcarrier signal for reducing the amplitude of a complex baseband time waveform of the OFDM symbol, and the transform section 3 applies fast inverse Fourier transform to the complex redundant subcarrier signal, together with the complex information subcarrier signal. Thus, the amplitude of the complex baseband time waveform of the OFDM symbol is reduced.

Title: Lithium secondary battery
Inventor: SUGANO NAOYUKI
IPC: H01M10/0569
Filed: 1990-03-16
Abstract: PURPOSE:To improve cycle life by using a mixed solvent consisting of ethylene carbonate, a specified ether compound, and lithium salt as the electrolyte of a lithium secondary battery, and specifying the mixing ratio of ethylene carbonate. CONSTITUTION:As the electrolyte of a lithium battery using a lithium alloy as a negative electrode active material and a transition metal chalcogen compound as a positive electrode active material, those in which lithium salt is dissolved in a mixed solvent of ethylene carbonate and an ether compound represented by the formula I (wherein R1 and R2 are hydrocarbon groups celeoted from CH3, C2H5, and C3H7) are used. The mixing ratio of ethylene carbonate in the mixed solvent is 25-75% by volume. Hence, charge and discharge cycle life in long-time discharge is improved. When the mixing ratio of ethylene carbonate is high, the viscosity is increased, and when it is low, the dielectric constant is reduced. Hence, the deterioration of the battery by long-time discharge is prevented.

Title: Cleaning device
Inventor: ASAKAWA TOSHIYUKI
IPC: G03G21/00
Filed: 1982-04-16
Abstract: PURPOSE:To prevent satisfactorily an accident caused by forgetting either one of an operation, by exactly interlocking a setting operation and a blade attaching and detaching operation of a cleaning device which is freely attachable and detachable. CONSTITUTION:When screw-setting of a set-screw 11 is released, the left end side of a free torsion spring 10 turns clrckwise, contacts with a release lever 8, further turns to contact with the left end of a handle in common use part of said set plate 9, and stops (shown by a broken line). In this case, the release lever 8 is also turned clock-wise, and the cleaning blade is moved to a separating position from an image carrying body. That is to say, the torsion spring 10 is energized clockwise, and the image carrying body separating operation of the blade 8 can be completed by only a release operation of the set-screw 11. The operation for fixing the release lever 8 to its release position is unnecessary. The setting operation is executed only by reversing said operation, therefore, it is extremely simple.

Inventor: MATSUO MASAYUKI
IPC: H04B1/26
Filed: 1981-04-28
Abstract: PURPOSE:To save power consumption of a superheterodyne receiver, by supplying power separately to a PLL frequency synthesizer and other circuits periodically and changing the period selectively. CONSTITUTION:A power is always given from a DC power supply to an oscillation circuit 28 giving signal to a reception controlling circuit 19 and a synthesizer SYN controlling circuit 27, and a switch 32 for oscillating frequency change is provided. When a switch 32 is closed at a time t1, the frequency is higher and the switching period of switches 18 and 19 controlled by the circuits 19 and 27 becomes faster. The circuit 27 closes the switch 26 by a time W1 to supply power from a power supply 17 to a PLL frequency SYN3 and interrupts the switch 26 for the time W2. The circuit 19 closes the switch 19 in the time W3 to supply power to each circuit other than the SYN3 and opens the switch  19 for the time W4. The switch 26 closes faster than the time W3 by the time  W5 required for the locking of the SYN3, allowing sure reception at the time W3.

Filed: 1992-03-23
Abstract: PURPOSE:To avoid tone influences of the surface recombination and to enable also the analysis in the depthwise direction when the recombination life of a minority carrier of a silicon substrate is measured. CONSTITUTION:A voltage is impressed by a power source 15 to a transparent electrode 12A coated over a transparent insulating substance 11A and an electrode 12B coated over an insulating substance 11B, whereby a depletion layer 13 is generated in a silicon substrate 3. Accordingly, a minority carrier generated in the silicon substrate 3 is prevented from scattering to the surface of the substrate, so that the surface recombination at the front and rear surfaces of the substrate is eliminated. When the thickness of the depletion layer is changed by changing the voltage of the power source 15, it becomes possible to analyze in the depthwise direction.

Title: Synchronizing time reduction system for pll circuit
Inventor: FUKUMOTO SHINICHI
IPC: H03L7/12
Filed: 1990-03-15
Abstract: PURPOSE:To reduce the time required for synchronization while keeping high accuracy by using a triangle wave as a control voltage to drive a VCO(Voltage Controlled Oscillator) circuit, and using a voltage when a rate of a change in a phase comparison output at that time is zero as the initial value of control voltage to the VCO circuit to activate a PLL circuit. CONSTITUTION:A rate of change zero detection means 12 detects a time of a rate of change in the output of difference between a frequency division output of the oscillated frequency of a VCO circuit 16 and an external clock frequency is almost zero. When the output of a rate of change zero detection frequency is generated, it is fed to a storage means 14 and a signal level of a triangle wave generating means 13 outputted from a selection means 15 is stored to the storage means 14. A control voltage generating means 11 sets the output of a signal level stored in the storage means 14 as an initial value to start the synchronization. Thus, accurate synchronization is reached in a short time.
