Title: Tap winding of transformer
Inventor: YAMAMOTO SHOICHI
IPC: H01F27/28
Filed: 1989-04-08
Abstract: PURPOSE:To prevent the generation of local excessive heating of an iron core and an iron core clamping fittings by making the total current of lead wires be cancelled as a whole. CONSTITUTION:A tap winding is divided into an inner layer tap winding 3A and an outer layer tap winding 3B; lead wires 6A, 7A are led out from the upper part and the lower part of the inner layer tap winding 3A and the outer layer tap winding 3B whose directions of winding are mutually inverse. In order to be able to alternately use each tap of the inner layer tap winding 3A and the outer layer tap winding 3B, the upper lead wires 6A (13', 15', 17', 19', 13, 15, 17, 19) and the lower lead wires 7A (12, 14, 16, 18, 14', 16', 18', 20) are wound in the manner in which the inner layer tap winding 3A and the outer layer tap winding 3B are alternately connected in order. By this constitution, the lead wire current of the inner layer tap winding 3A and the lead wire current of the cuter layer tap winding 3B become inverse in direction, so that the total currents of the lead wires are cancelled as a whole. Thereby the tap winding of a transformer, wherein the generation of local excessive heating of an iron core 1 and iron core clamping fittings 8, 9 is prevented, can be obtained.

Title: Ceiling current supplying circuit
Inventor: KAWANA MASAKI
IPC: H04M19/00
Filed: 1989-04-07
Abstract: PURPOSE:To prevent the thermal destruction of a ceiling current supplying circuit occurring even when an abnormal voltage is applied by directly mounting a PTC resistor on a substrate. CONSTITUTION:The subject circuit is the one in which the PTC resisters RP1 and RP2 having positive temperature coefficients such as a posistor are connected in series to film thickness resistors R2 and R4, and a film thickness resistor 12 is provided on one plane of a ceramic substrate 10 as resistors R1-R4, and the PTC resistor 13 is provided on the other plane of the substrate 10. When an abnormal voltage source 3 is applied on a subscriber line 5, the resistance values of the PTC resistors RP1 and RP2 are increased by generating heat in the ceiling current supplying circuit 1, and a current that flows on the circuit 1 is limited, and the heating value of the circuit 1 can be suppressed less than a constant value. Thereby, the thermal destruction of the circuit 1 can be prevented from occurring.

Title: Ultrasonic wave flowmeter
Inventor: TAKAMOTO MASAKI
IPC: G01F1/66
Filed: 1983-05-20
Abstract: PURPOSE:To obtain a flowmeter characterized by a simple constitution and high measuring accuracy, by measuring the flow rate of a fluid flowing in a flow path, based on a time period from a rise-up time to the attainment of a specified level. CONSTITUTION:A trigger circuit 1 simultaneously starts oscillators 2 and 3, turns ON an SR flip flop circuit 12, and opens a gate circuit 14. Clock pulses from a clock pulse generating circuit 13 are counted by a counter 15. Ultrasonic waves are transmitted by ultrasonic-wave transmitting devices 4 and 5, received by ultrasonic-wave receiving devices 6 and 7, and added by an adder 10. The result is converted into a signal. A peculier level spot appears in the output signal from the adder 10, and it is detected by a waveform shaping circuit 11. Then the flip flop circuit 12 is turned OFF. Thus the time period from the ultrasonic wave transmission to the generation of the peculier level is measured by the counter 15. Since the time period from the receiving to the generation of the peculiar level is constant, the transmitting time period of the ultrasonic waves in the fluid to be measured can be obtained from the counted value of the counter 15.

Title: Apparatus for converting physical quantity
Inventor: KIMURA ATSUSHI
IPC: G01D5/24
Filed: 1983-05-20
Abstract: PURPOSE:To impart long damping time constant characteristics by a capacitor having small capacity, by providing an opening and closing means for changing the time constant in a smoothing circuit, driving the opening and closing means by ON and OFF duty pulses, which are obtained based on a pulse signal from a detecting circuit, and controlling the time constant of the smoothing circuit. CONSTITUTION:A pulse signal, whose ON and OFF duty ratio is associated with variable electrostatic capacitors CH and CL, is imparted to a counter CT2 from a counter CT1. Then the frequency of this signal is divided, and pulse signals S1-S4, whose frequency divided ratios are 1/8, 1/16, 1/32, and 1/64, respectively, are imparted to fixed contact points S1-S4 from an output terminals. A movable piece M1 is moved so as to select the desired signal out of said puls signals, and a switch SW1 is driven. An opening and closing means SW1 in a smoothing circuit FL1 is closed during the time period only when the high level pulse signal is imparted. During the other time period, since the signal voltage is maintained, the smoothing circuit operates as if the time constant were larger. When the movable piece M1 is contacted with a fixed contact point S5, the switch SW1 remains closed, and the time constant of the smoothing circuit FL1 becomes the minimum.

Title: Shared branching filter for orthogonal double polarized wave
Inventor: TAKEDA FUMIO
IPC: H01P1/213
Filed: 1981-06-11
Abstract: PURPOSE:To obtain a shared branching filter for orthogonal double polarized wave, by forming a tapered waveguide with a square waveguide and varying the taper in a curve. CONSTITUTION:The higher order mode produced from a square tapered waveguide 3 is equal to a TM2 (square shape) mode and opposite to a TM11 (round shape) mode of a round waveguide, and the cutoff frequency fCTM21 is equal to fCTM21=335.19/a2 (GHz). While the cutoff frequency fCTE10 of the basic wave TE10 (square shape) mode of the square waveguide is equal to 149.9/a2 (GHz). Accordingly fH/fL is set at 2.236-fold value (2.08 with the round tapered waveguide) to realize a wide band. At the same time, a change of position is reduced for the equivalent reflective surface of a tapered waveguide 3 to the wave within the band fL by varying the taper in a curve. As a result, the optimum position has no big change by the frequency for a coupling hole 2 for the branching of the wave of fL. Thus the brahching filter characteristics can be improved over a wide range for the wave of fL.

IPC: H04N9/835
Filed: 1990-04-04
Abstract: PURPOSE:To improve operability and to prolong play time by reproducing digital video signals after reproducing analog video signals. CONSTITUTION:When playing a disk, identification information outputted from a digital data generation source 39 is read. When it is decided based on this read information that the class of the disk to be reproduced is a composite disk, signals are read from multiple recording areas and one of the analog video signal and the digital video signal decided in advance is reproduced and outputted from a video signal source 31 or a video signal source 37. After finishing the output, the signals are read from the multiple recording areas and the other kind of signals are reproduced and outputted. Thus, since the analog video signals are reproduced first and afterwards the digital video signals are reproduced in the case of the composite disk including the analog video signals and the digital video signals, the user enables operation without distinguishing the normal video disk and the composite disk, and the play is automatically prolonged.
