Title: Filter circuit
Inventor: OKADA TAKAFUMI
IPC: H03H11/12
Filed: 1980-05-17
Abstract: PURPOSE:To constitute a filter suitable for circuit integration, by using a variable gain amplifier and a capacitor. CONSTITUTION:When a signal is fed to the base of a transistor (TR)Q1, this signal is amplified differentially by TRs Q1, Q2 in an amplifier 2 and picked up at the  emitter of a (TR)Q9 after being amplified differentially by TRs Q6, Q7. A capacitor C1 is in parallel connection between the input and output terminals of the amplifier 2, and according to the Miller's effect by the capacitor C1, a capacitance C viewing the amplifier 2 from a resistor R1 is C=C1A1, if the naked gain of the amplifier 2 is taken as A1. Thus, this circuit operates like an LPF, and the output of the LPF is picked up at terminal T2. Further, the cutoff frequency fC of the output of the LPF is fC=1/2piC1A1R1. Even if the value of the resistor R1 is in variance, the cutoff frequency fC can be compensated by changing the gain A1 of the amplifier 2 toward reverse direction, through the change in the collector current of a (TR)Q3.

Title: Formation of helical conductor
IPC: H01F6/06
Filed: 1992-03-24
Abstract: PURPOSE:To manufacture a high strength and high conductivity helical coil conductor by coiling a wire whose cross section is straight angle-shaped around a cylinder spirally, applying compression force to the wire drawing from the longitudinal direction of the cylinder and correcting the trapezoid-shaped wire drawing in its cross section and correcting the shape into straight angle in its cross section and then finishing both the inner and outer surfaces of the wire drawing. CONSTITUTION:With tensile force applied to a cylinder-shaped inner mold, a copper belt is mechanically coiled in such a fashion that the clearance between the copper belts may be minimized, thereby obtain a spirally-shaped coil 2114. After its winding, if tensile force is removed, the size of the coil will be increased by the portion of resultant elastic deformation. Then, an outer mold 15 in addition to the inner mold is inserted into the enlarged coil. The trapezoid-shaped cross section of each layer of the spirally-shaped coils 14 is subjected to forced deformation and returned to the original straight angle. Then, the inner mold 13 is removed and a coil conductor 17 is obtained. Furthermore, all the surfaces between the inner and outer molds and each layer are mechanically finished, thereby producing a coil conductor 19 having a finally-shaped inner layers 20a to 20h.

IPC: G05F1/455
Filed: 1983-04-15
Abstract: PURPOSE:To feed assuredly the switching state of a contact connected to an AC power supply without using any smoothing circuit, by performing the signal input processing only when the input current is set higher than a fixed level. CONSTITUTION:The switching state signal of a signal contact 2 connected to an AC power supply 1 is supplied to an input terminal 8a of a digital circuit 8 via input resistances 4 and 5 after undergoing the full wave rectification 3.

Filed: 1988-03-18
Abstract: PURPOSE:To prevent bouncing by suppressing a lift speed in a nozzle needle with a damper effect by fuel, when a valve is opened, and with a damper effect suppressing an outflow of fuel by an orifice. CONSTITUTION:A nozzle needle 9 is suppressed in its lift speed because the nozzle needle 9 is damped by pressurizing fuel in a spring housing chamber 16 by the nozzle needle 9 under a condition that a pressure of the fuel in the spring housing chamber 16 is not easily relieved by an orifice 20. Further because the volume of the spring housing chamber 16 is decreased by a pipe part 17a, the fuel pressure in the spring housing chamber 16 easily increases for a lift of the nozzle needle 9, more increasing a damper effect for the nozzle needle 9.

The inversion preventive layers are constituted from P<-> type regions 29 in low concentration and P<+> type regions 30. Accordingly, the generation of current leakage is prevented, thus increasing working speed and improving reliability.
