Title: Disaster signalling system by geostationary satellite
Inventor: SUGIMOTO OSAMU
IPC: G01S3/20
Filed: 1985-02-26
Abstract: PURPOSE:To grasp the position of disaster by utilizing a geostationary satellite without a transmitting signal from the ship in disaster by capturing a radio wave of the ship by the geostationary satellite, and receiving the antenna beam scanning direction and the intensity of the received electrical field at a ground station. CONSTITUTION:A beam scanning type antenna 7 of a transmitter and a receiver loaded on the geostationary satellite is driven for high speed scanning with a pencil beam 8 with a sufficiently narrow beam width. When a ship is in disaster, the transmitter position is scanned and the detected output signals indicative of the received field intensity is converted by a signal processing circuit 14 and transmitted by an antenna 10 to the ground station. Since the satellite is stationary relative to the ground station, the point of disaster is known from the beam direction of the maximum field intensity. Therefore, the disaster information can be easily obtained by utilizing the geostationary satellite without direct transmission from the ship to the ground station.

Title: Ultrasonic flaw detecting device
Inventor: SUGANO SATORU
IPC: G01N29/04
Filed: 1987-02-20
Abstract: PURPOSE:To easily find a defect by supplying a brightness adjustment signal to a display means and increasing its brightness when the level of an echo signal exceeds the level of the output signal of a filter circuit. CONSTITUTION:An original signal obtained by a probe contains the echo signal E generated by reflection at the defect. A signal F passed through the filter circuit 6, on the other hand, is filtered by the circuit 6 as a band-pass filter to cut its high frequency component. Further, a flaw detection gate generating circuit 10 indicates a prescribed flaw detection section, so an analog switch 7 is turned on, and an analog switch 8 is further switched on when the signal E exceeds the threshold value, so that when a defect is found within a prescribed flaw detection range, the output of the circuit 6 is inputted to a comparator 9. Then the signal F is compared 9 with the signal E and the comparator 9 outputs the brightness adjustment signal over a section where the level of the signal E exceeds the signal F. While this brightness adjustment signal is outputted, the brightness of a waveform displayed on a CRT display device 3 is increased and the defect is easily found.

Abstract: PURPOSE: To obtain a connector which lessens the unequal temp. of a resin, is capable of suppressing the intrusion of air bubbles and further, features high accuracy and good transferability by providing the connector with a resin injection path for connecting resin injection holes and V-grooves for bold pins. CONSTITUTION: This optical connector is molded in parts of cavities 11, 21 by heating metal molds 1, 2 and a core 3 and injecting an epoxy resin therein.

Filed: 1979-03-29
Abstract: PURPOSE:To secure the flatness property for the capacitive load even to the low frequency input via the broad-duration pulse, by supplying repetivively the narrow- duration pulse to the DC cut-off coupling element. CONSTITUTION:The serial circuit of a pair of switching TRQ1 and Q2 plus Q3 and Q4 is connected to DC power source VS. And then capacitive load PDP such as the gas discharge element or the like is connected to the joint of TRQ1/Q2 and Q3/Q4, and pulse transformers T1-T4 functioning as the DC cut-off coupling elements are connected to the input side of the switching TR.

As a result, the occurrence can be eliminated for the sag at the flat area when the broad-duration pulse is supplied.
