Title: Pwm controller
Inventor: TAKEUCHI HIROSHI
IPC: H02J3/38
Filed: 1990-06-06
Abstract: PURPOSE:To suppress the quantity of generated higher harmonics of converter power by generating a PWM carrier signal, whose zero cross point accords with the phase signal being corrected to synchronize with a PWM reference wave signal. CONSTITUTION:A three-phase/two-phase converting circuit 10 converts a three- phase voltage signal S100 into a two-phase voltage signal, while a feedback signal generating circuit 16 generates a feedback signal S103, and adds it to a phase difference detection circuit 11 through a D/A converter 17. The phase difference detection circuit 11 performs the following operation based on these signals so as to seek the phase difference between the converted two-phase signal and the feedback signal. Subsequently, the harmonics ingredients within this phase difference signal are removed by a loop filter 12, and a digital voltage control oscillator 13 generates such a pulse signal S104 as to make the phase difference signal zero. These pulse signals S104 are counted by a phase counter 14, and digital phase signals theta synchronous with the system voltage are outputted.

Title: Manufacture of non-aqueous secondary battery
Inventor: SAKATA TADASHI
IPC: H01M10/05
Filed: 1991-05-22
Abstract: PURPOSE:To enhance productivity and increase a battery capacity by conducting an electrochemical reaction between metal oxide and lithium of a positive electrode in the battery. CONSTITUTION:Lithium 4 is attached onto a side of a separator 3 of a positive electrode 1 obtained by pressurizing a mixture of manganese dioxide, graphite and polytetrafluoroethylene. A mixture of a carbon material and a binding agent is pressurized, thus obtaining a negative electrode 2. The separator 3 is made of a micro-porous polypropylene film. The above members are contained inside a positive electrode can 5 and a negative electrode can 6. A non-aqueous electrolyte where LiClO4 is solved is injected into a mixture solvent of propylene carbonate and 1,2-dimethoxyethane. At this time, the manganese dioxide and lithium of the positive electrode are electrochemically reacted so that the lithium is contained inside the positive electrode. Consequently, a process of containing lithium before assembling work of a battery can be unnecessary. Furthermore, the content of lithium is increased, thus enhancing productivity and increasing a battery capacity.

Title: Method for adjusting vehicle body posture of combine
Inventor: YOSHIMURA FUMIO
IPC: A01D67/00
Filed: 1990-06-05
Abstract: PURPOSE:To efficiently and stably perform a reaping work by preferentially subjecting a vehicle to a longitudinally horizontal control when a grain straw sensor does not detect grain straws or until the vehicle travels for a constant distance after the detection of the grain straws and preferentially subjecting the vehicle to a laterally horizontal control under conditions except the cases. CONSTITUTION:When a vehicle travels from a butt to a non-reaping row and is largely tilted in the longitudinal direction, the vehicle is corrected to a horizontal state due to the longitudinally horizontal control preferentially set with a controller 21 wherein a pitching cylinder 17 is elongated or shortened by the action of pitching valve 18 caused by the front-lower or rear-lower solenoid 26, 27 on the basis of the detection of a longitudinal tilt sensor 33 and the control is performed based on the detected value of a longitudinal stroke sensor 36 and a longitudinal tilt standard value set in the controller 21. The vehicle reaps a non-reaped row and travels under the longitudinal horizontal control and after a grain straw sensor 31 detects the grain straws, the travel distance is counted with a vehicle speed sensor 30 to reap the grain straws for a constant set distance under the control. After the grain straws are reaped for the constant distance under the control, the control is switched with a laterally horizontal control and the reaping work is continued.

Title: Semiconductor device
Inventor: SATOU MAKI
IPC: H01L29/78
Filed: 1978-11-30
Abstract: PURPOSE: To enhance characteristics by elaborating the way the gate and drain electrodes are leading out in an FET employing an insulator film in the gate area.  
     CONSTITUTION: n + -Layers 2, 3 are formed on p-type Si substrate and covered with an insulator film 4 and a resistor film 5 so that they extend over the n + -layer 3 through thick insulator film 6. The entire surface is covered with an insulator film 7, and windows are selectively opened on the films 7, 6 to form an electrode S on the layer 2 and an electrode G on the extended part of the film 5. On the layer 3, a through-hole is drilled through the films 7, 5, 6 to form an electrode D which lies on the insulator film 6 along the layer 3 and contacts the layer 3 through the hole 8. The resistor film used is O 2  added polycrystalline Si. In this structure, the n- layers 2, 3 have the same diffusion form to result in an enhanced characteristic as a bi-directional transistor. Also, the layers 2, 3 can be formed in small size to reduce the junction capacitance. The gate-to-layer 3 capacitance is added with the series resistance of the resistor film 5 outside of the layer 3 to permit the switching spike to be eliminated. Since the electrode D is leading through the hole 8, the drain resistance falls and thus the ON resistance is lowered.

The mechanism 2 follows the instructions of the computer 9 to move a dust measuring air take-in port 3 to the dust measuring position. When the inlet 3 is moved to the dust measuring position, the computer 9 issues a command for a dust measuring device 5 to start the measurement of dust through a dust measured value output cable 6. The value of the dust introduced from the inlet 3 through a dust measuring air introducing pipe 4 is measured by the measuring device 6 to be recorded on a recorder 7 through the cable 6.

Title: Demodulator for multi-channel record
Inventor: SUZUKI FUJIO
IPC: H03D3/02
Filed: 1977-12-12
Abstract: PURPOSE:To produce demodulated signals having their distorsion reduced by detecting the distorsion, which is generated during the modulation of reproduced angularly-molulated signals, with the use of a second phase locked loop (PLL)  thereby to control the lock range of a first PLL circuit. CONSTITUTION:When the reproduced signals containing the distorsion of a multi- channel record due to the non-linearity, higher harmonics and drop-out of a transmission system are fed, a voltage according to the distorsion is generated by a synchronous detector 30 by the phase difference between the output signals of a voltage control oscillator of a second PLL circuit 28 locked in a wide range and the reproduced angularly-modulated signals. By this voltage, the range of the first PLL circuit is controlled to be narrower so that the distorsion can be eliminated by a synchronous detector 33 and an LPF 34. As a result, a signal processor 35 does  not responde to the distorsion so that the signal demodulation processing having its distortion reduced can be accomplished through the processor 35.
