Patent JP-S58182318-A (JP)
Title: Frequency-voltage converter
Inventor: TANAKA TAKUMI
IPC: H03K9/06
Filed: 1982-04-19
Abstract: PURPOSE:To attain the device of high accuracy, by using the principle that the phase difference is a linear function of the frequency of a rectangular input signal and converting the input frequency into an output voltage. CONSTITUTION:A comparator 4 detects the phase difference phi between a leading edge of a reference signal 2A delayed from the leading edge of a rectangular signal 1A by a prescribed time T0 and a trailing edge appeared next to the leading edge of the signal 1A. The phase difference phi (radian) is expressed as phi=pi(1-2T0f), where T is the period of the signal 1A and (f) is the frequency (=1/T), then the phase difference phi is a linear function of the frequency (f) of the rectangular input, because pi and T0 are constant values independently of the frequency (f). A low pass filter 5 converts the phase difference phi into a DC voltage 5A proportional to the phase difference phi, then the DC voltage 5A corresponds with the frequency of the signal 1A. The frequency detecting range is decided by the prescribed time T0 and the range is 0-2f0.

Abstract: PURPOSE:To prevent fluctuations of detection characteristics stopping neither a charging nor discharging current from flowing the capacitance of the negative feedback network of a control amplifier and capacitances of a smoothing circuit even if a reference voltage from a reference voltage generator fluctuates. CONSTITUTION:Parts in an IC shown by the broken line are constituted in a monolithic semiconductor integrated circuit. One-side terminals of capacitances C8 and C9 of a smoothing circuit 15b are connected to no.4 and applied with a DC reference voltage VREF generated by a reference voltage generator 22.

Filed: 1984-04-02
Abstract: PURPOSE:To reduce the capacity of an antenna and also to stabilize the impressed voltage by dividing a power supply into plural different power supplies and attaching specific one of these power supplies within an attachment surface of a transmission/reception device and at a position where no transmission/reception device exists. CONSTITUTION:Transmission/reception devices 131-13n are used as antenna elements, and the drive voltage is supplied to these devices 131-13n from a distribution circuit 14 via an interface connector 9. While stabilized power supply devices 201-20m are put into the areas where devices 131-13n are not provided. The devices 201-20n have different types for gate bias, drain bias and control circuit, for example, and supply the stabilized voltage to the circuit 14 after receiving the electric power of a non-stabilized power supply 15. Thus it is possible to reduce the antenna capacity and also to improve the stability of the impressed voltage owing to reduction of the length of the feeder of the stabilized power supply.

Title: Servo recorder
Inventor: OTSU HIROSHI
IPC: G01D3/06
Filed: 1985-03-29
Abstract: PURPOSE:To prevent the damage due to shake-off of a carriage by fixing the input applied to a servo system to an upper limit value in case of over scale and fixing it to a lower limit value in case of under scale. CONSTITUTION:A measured signal X impressed to an input terminal 31 is amplified by a preamplifier 32 and is read into a microprocessor muP 35 through an A/D converter 33 and is subjected to the arithmetic processing. The muP 35 compares an output X1 of a D/A converter 39 with the lower limit value and the upper limit value of the effective span of the carriage. If the value of the input X falls and the output X1 is smaller than the lower limit value, the muP 35 fixes the output X1 of the converter 39, namely, the input applied to the servo system to the lower limit value independently of the input. If the input X is increased and its value will exceed the upper limit value, the muP 35 fixes the output X1 to the upper limit value. As the result, the carriage is stopped in a position before striking against a mechanical stopper.

Title: Division system
Inventor: MIYAMOTO KIYOBUMI
IPC: G06F7/535
Filed: 1989-03-20
Abstract: PURPOSE:To improve the speed of an operation cycle by looping back the output of a carry preservation adder without allowing it to pass through a carry foresight adder and continuing the operation cycle. CONSTITUTION:The inverse approximate value of a divisor is processed by using a multiplier. The divisor of a system obtaining a partial quotient is changed so as to loop back a carry and a sum outputted from the carry preservation adder CSA to a division decoder 3 since it has looped back the output of the carry foresight adder CPA thus far. The division decoder 3 is constituted in such a way that it can directly decode two inputs and control multiplier gates 4 and 5. Thus, the operation cycle can be continued without obtaining an operation result in carry CPA whose operation speed is comparatively slow, and the processing speed can be improved, whereby a system can be miniaturized.

Filed: 1981-05-01
Abstract: PURPOSE: To perform easy and sure loading of a disc, by the constitution that a positioning through-hole and a projection are mated when a disc is loaded on a disc support and the disc is pressed and fixed with a compression spring of a pressing body.  
     CONSTITUTION: When a disc 7 is loaded on a support plane 13a of a disc support 13, a positioning through-hole 2 and a positioning projection 13b are mated to regulate the position. When a guide hole 17 is mated to a rotary shaft 10 and a main body of a disc holder 14 is pushed in, a slope of a lower end hook 22a of a latch lever 22 contacts the upper end surface of the rotary shaft 10 and  when the main body is further pushed in, the latch lever turns against an energizing force of a compression spring 24 and overrides the upper end circumference of a latch groove 19 and drops in the groove 19 to be held in latch state  with the compression spring 24. In this case, a pressing body 16 pushes a disc 7  to a support 13 via a compression spring 25. When the projection 22c of an  operation section 20 is pressed, the latch between a latch 18 and the groove 19 is released. Thus, the disc 7 can easily and surely be loaded.

Abstract: PURPOSE:To reversibly obtain a transparent and opaque state change in conformity with heating and cooling by forming a thermal sheet by the coating with a reversible thermal material in a film form to reversibly generate a transparent and opaque state change by heating or cooling. CONSTITUTION:A reversible thermal material is applied in a film form to form a thermal sheet and a transparent and opaque state change is reversibly generated by heating or cooling the thermal sheet.
