Title: Azimuth gage
Inventor: KANO YOSHIO
IPC: G01C17/08
Filed: 1981-01-27
Abstract: PURPOSE:To detect the azimuth excellently and accurately by attaching a magnet to a float, floating said float on liquid, and rotatably supporting the float at the center in a solid body by surface tension between the float and the solid body. CONSTITUTION:The float 22 to the lower part of which the magnet 21 is attached is floated in water 25 in a container 29. The surface of the water becomes a convex shape 25A by the surface tension between the ring shaped solid body 23 and the float 22. The float 22 is supported at the center in the solid body 23 so that it can be freely rotated. A Hall element 26 is attached on the north side of the side wall of the container 29. A voltage is applied by a power source 41, and an electric field and a magnetic field caused by a magnet 21 are crossed at a right angle. An electromotive force is obtained from the plane where the electric field and the magnetic field are crossed at a right angle. An output E is obtained through an amplifier 42. When the output E becomes the positive maximum, the Hall element 26 is located to the north. When the rotary angle of the magnet 21 is +90 deg., the output E becomes zero, and the Hall element is located to the east. Thus the azimuth can be detected excellently and accurately.

Title: Clock signal modeling circuit
Inventor: BOKU SEIMAN
IPC: H03K5/14
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To reduce a clock access time and current consumption by sampling a delayed external clock signal, comparing sequentially sampled signals and adjusting the output of a comparison signal through the switching operation. SOLUTION: Upon the input of an external clock signal CLK- IN, delay blocks D1-Dn of a delay section 10 delay the clock signal CLK- IN and delay clock signals CLK- D1 to CLK- dn are outputted to a sampling section 20 and an output section 40. Then flip-flop circuits FF1-FFn of the sampling section 20 sample the clock signals CLK- D1 to CLK- Dn at a rising edge of the signal CLK- IN to provide the output of noninverting output signals Q1-Qn, and comparators C1-Cn of a comparator section 30 compare sequentially the signals Q1-Qn to outputs comparison signals CS1-CSn. Thus, the output section 40 outputs one clock signal in the clock signals CLK- D1 to CLK- dn received from the delay blocks D1-Dn in response to the signals CS1-CSn.

Title: Mosfet driving circuit
Inventor: SHIMIZU HISAO
IPC: H03K17/687
Filed: 1981-01-28
Abstract: PURPOSE:To increase the switching speed, by discharging a capacitance between the gate and source of an MOSFET via another winding of a transformer, when the MOSFET turns off, in a circuit driving the MOSFET through the output of secondary winding of the transformer. CONSTITUTION:Mutually complementary driving pulses are applied to terminals 6, 7. When a transistor (TR) TR2 turns on, an MOSFET1 is driven with the output of the secondary winding N1 of a transformer T1 and turned on. When the driving pulses are inverted, a TR1 turns on, and charges stored in a capacitance between the gate and source of the FET1 are discharged via a ternary winding N3 and a capacitor C, and the FET1 turns rapidly off. When the  charges are discharged, an inverse voltage is generated in the ternary winding N3 and the FET1 is kept off.

Title: Constant current circuit
Inventor: MATSUYAMA EIICHI
IPC: H03F3/34
Filed: 1987-01-19
Abstract: PURPOSE:To obtain a constant current circuit having high accuracy by using a 2nd transistor TR which turns off a switch circuit when a 1st TR is turned on so that the constitution of the circuit of the next stage is simplified. CONSTITUTION:When a power supply B is applied with the input control voltage V kept at a high level, a transistor TRQ4 is turned on together with a switch S turned off. Thus no output current IOUT is produced. While both TRQ3 and Q4 are turned off when the voltage V is kept at a low level. Thus the current IOUT flows. In such a way, the switch S is added to turn off the TR when its constant current output is not needed so that a constant power output is obtained. As a result, the constitution of the circuit of the next stage is simplified and the accuracy of a constant current circuit is improved.

Title: Amplitude modulation circuit
Inventor: YOSHIKAWA YOSHIKAZU
IPC: H03C1/02
Filed: 1979-02-06
Abstract: PURPOSE:To prevent the interference to the radio unit in the vicinity, by preventing the spread of the carrier frequency spectrum with amplitude modulation, through the provision of the delay circuit taking longer the leading and trailing time of rectangular waves and through the intermission of carrier with the output of delay circuit. CONSTITUTION:When the transistor 21 of the delay circuit IV taking longer the leading and trailing of the rectangular waves of the rectangular wave osicllation circuit V is ON, electromagnetic waves are radiated since miximum carrier current flows to the bar antenna coil 6 of the carrier power amplifying circuit II. When the transistor 21 is OFF, the transistor 9 is OFF, no current flows to the bar antenna coil 6 and no electromagnetic waves are radiated. Since the leading and trailing of the amplitude modulation signal constitute exponential curve having the time constant of the (resistor 23)X(capacitor) 22 of the delay circuit IV, the harmonics included in  the amplitude modulation signal is less and the giving of electromagnetic wave interference is less.
