Title: Intermediate antenna for multiwave
Inventor: KATOU YASUTAROU
IPC: H01Q5/35
Filed: 1980-02-01
Abstract: PURPOSE:To energize intermediate-wave antennas for multifrequency efficiently, by providing a circuit which shows infinite impedance to the output wavelength of the transmitter itself and also shows zero impedance to the output wavelength of other transmitters. CONSTITUTION:A power lambda1 in wavelength output from a transmitter T1 is not absorbed in a circuit Q1 2 but fed to a power feeding conductor F1 from the energizing point A because the circuit Q1 2 shows infinite impedance to the wave lambda1 in wavelength, and also it is given to an iron tower T and other feeding lines F2. On the other hand, the circuit Q1 2 of the power feeding conductor F2 shows zero impedance to the wave lambda1 in wavelength, then the lower end of the conductor F2 is grounded to the wave in wavelength lambda1. Thus, the wave lambda1 in wavelength does not cause interference through flowing to the transmitter T2. Similarly, the wave lambda2 in wavelength does not cause interference through flowing to the transmitter T1 fed from the lower end A2 of the conductor F2. Thus, the antenna in common use for two waves can make energizing operation for two waves lambda1 and lambda2 in wavelength.

Title: Through-current preventing circuit of output inverter
Inventor: AOKI HIROSHI
IPC: H03K19/00
Filed: 1985-01-24
Abstract: PURPOSE:To prevent a through-current with a simple element by connecting an output of a control P channel and control N channel respectively to a gate of P and N channels of an output inverter and forming a resistor on a separa tion region between the control P channel and the control N channel. CONSTITUTION:When a level of a terminal (a) is inverted from1 to 0 as shown in a figure (a), a P channel P2 is turned on. Thus, a terminal (b) is charged by a time constant decided by an on-resistance R1 of the P channel P2 and a gate capacitance C1 and since the time constant is small, the terminal (b) is charged rapidly as shown in a figure (b). When the level of the terminal (a) is inverted from 0to 1, the M channel N2 is turned on. Thus, the terminal (c) is discharged rapidly by the time constant comprising the on-resistance R2 of the N channel N2 and the gate capacitance C2 as shown in a figure (c). On the other hand, since the terminal (b) is in the way of a resistor R0, the level is discharged slowly as shown in a figure (b). Thus, the P channel P1 and the N channel N1 are both turned off for a time t4.

IPC: G08B25/10
Filed: 1990-01-19
Abstract: PURPOSE:To constitute the device so that a person having a transmitter can communicate with a person having a receiver by providing the receiver for demodulating and encoding a radio wave signal from the transmitter for sending out a radio wave based on a specific code train and generating an output signal only at the time when the obtained code train and a code train determined internally in advance coincide with each other. CONSTITUTION:A radio wave sent out of a transmitter TR is received by a receiving part through an antenna ANT, and this received signal is demodulated in a processing part 6, encoded and inputted to a comparing part 7. In that case, in a setting part 8 with a monitor, a coded train determined in advance is set, therefore, in the comparing part 7, only when both code trains of this set code train and the code train encoded by the processing part 6 coincide with each other, an output signal is sent out. In such a way, an exact communication can be executed from a person having the transmitter TR on the sea to a person having the receiver 5 on the shore.

IPC: H02M3/335
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To materialize a small-sized and light-weight power unit by omitting a smoothing reactor. SOLUTION: Rectangular wave voltage of high frequency is generated from DC input voltage by first and second converters 3 and 4, and the output voltages of the first and second converters 3 and 4 are insulated and transformed, and further they are rectified with first and second rectifiers 7 and 8, and the outputs after rectification of these first and second rectifiers 7 and 8 are coupled with each other in parallel into DC voltage. This DC voltage is inputted into an inverter 10 not through a smoothing reactor, and is converted into AC voltage, and is outputted as AC voltage. A power conversion control circuit, which converts this DC input voltage into specified AC voltage and outputs it, is switches the first and second converters 3 and 4 such that they switch at a conduction ratio of 50% or over, sliding their phases by 90 deg. each.  Hereby, the DC voltages being rectified via the first and second rectifiers 7 and 8 and are coupled with each other in parallel prior to output do not contain a ripple voltage, which dispenses with a reactor for smoothing.

Title: Electric signal-air pressure conversion unit
Inventor: ODAJIMA KATSUHIKO
IPC: G01D5/42
Filed: 1985-01-25
Abstract: PURPOSE:To control an air pressure by using a pressure sensor with high accuracy by acting the pressure of a control object such as pressure tank as a direct feedback signal to a pressure sensor. CONSTITUTION:The free end of a nozzle flapper mechanism 22 consisting of an electrostrictive element 24 is displaced in the direction where a nozzle 18 is closed when the voltage to be impressed to said mechanism increases. The quantity of the air ejected from the nozzle 18 is thereby decreased and the pressure in a nozzle back pressure chamber 16 is increased. This pressure acts atop an upper diaphragm 30. As a result, the equil. state is broken and the upper diaphragm 30 and a lower diaphragm 32 descend. An exhaust valve 34 and an inside valve 36 formed integrally therewith descend. An air feed port 53 is therefore opened and part of the supply pressure from a supply port 38 is supplied to an output port 52. The output air pressure thus formed is supplied to a pressure tank 63, by which the intended function is attained.

Title: Wave-length discrimination type photo-detector
Inventor: NISHIDA KATSUHIKO
IPC: G01J1/44
Filed: 1979-02-05
Abstract: PURPOSE:To discriminate wave length with superior characteristics using only electric circuits by a method wherein the output of a semiconductor photo-detector is processed by electric operational circuit utilizing the spectral sensitive characteristics of the detector. CONSTITUTION:A wave-length discrimination type photo-detector is constructed by connecting an operational circuit to the output side of a semiconductor photo- detector obtained by providing P-N Junctions 2, 3 on a semiconductor which has more than two kinds of the different energy of forbidden band width, and connecting lead wires 5, 6 and 4 to each junction. If it is assumed that the wave lengths are L1, L2, and the spectral sensitive characterisrics of detectors A and B21, B22 are each 18, 19, the detecting portion B22 responses to only light L1, letting a light current L1(t) flow. The detecting portion A21 responses to both L1, L2 light, producing an output L1(t)+L2(t). Therefore, the difference L2(t) in outputs between the detecting portions of A and B via a differential amplifier 23 can be taken out. Thus, it is possible to discriminate wave lengths with superior characteristics using only electric circuits.

Filed: 1982-01-28
Abstract: PURPOSE:To carry out focusing automatically by comparing the first and second threshold values near the average density level of shaded picture detected through an optical system and a photographing signal and determining signal amount between threshold values.

Abstract: PURPOSE:To detect the direction of rubbing on the basis of an information on a running route between two points by providing a receiver receiving a running route information signal, a selecting means to select data on destination corresponding to the direction of the goal and a previously notifying means to notify the direction of running previously. CONSTITUTION:A running route information signal received by a receiver 1 is taken in CPU 3 through an input/output circuit 2.
