Title: Leakage detecting system
Inventor: KAKO AKIYOSHI
IPC: G01M3/04
Filed: 1988-02-22
Abstract: PURPOSE:To certainly and quickly detect a gas leaking state by controlling the monitoring direction of a TV camera by means of a gas leakage detecting signal so that the camera can be directed to a gas leaking part. CONSTITUTION:The inflammable gas detector 12 of a leakage detecting system 10 issues alarm signals and informs an operator of gas leakage when gas concentration exceeds a previously fixed reference value due to gas leakage. The alarm signals are sent to a control section 15 and a TV camera 16 which monitors the detector 12 issuing the alarm signals is selected. Then the positional data of an estimated leaking point are fetched from a memory 28 and the momentum of a camera driving device 17 is calculated, and thus, the camera 16 is fixed toward the detector 12 which detects the gas leakage. The video of the camera 16 is displayed on a monitor TV set 18 and data of leaking point, gas concentration, gas scattering direction, direction of the wind, etc., together with the arrangement plan of a plant 11 are displayed on a CRT display 19. Therefore, the operator can take a necessary countermeasure by watching the display. Therefore, a leaking state can be detected quickly and certainly and an accident resulting in injury or death which tends to take place when a person goes to the leaking site for confirmation can be prevented. Moreover, since the plan 11 can be stopped from the control section 15, a serious accident can be prevented.

Title: Communications device of sound and picture
Inventor: OOI TAKAHITO
IPC: H04N7/14
Filed: 1984-03-02
Abstract: PURPOSE:To make necessary communication capacity smaller by using a sound band of 300-3,400Hz for transmission of a picture during a silence period. CONSTITUTION:When a sound enters a transmitter 1, a sound detection part 3 operates through an amplifier 2, and contact points A and C of a switch 4 are closed and contacts V and C are opened. As a result, a sound signal enters a transmission/reception separation circuit 5 and transmitted to a telephone line 6. A picture signal from a batch photographing part 7 is split as a digital signal to a buffer 8 at every one screen and accumulated. When a sound to the transmitter 1 stops, the sound detection part 3 detects the stoppage to open the contacts of A and C and close those of V and C, respectively. Simultaneously said detection part 3 actuates a pointer 9 and transmits picture element data of the buffer 8 to a modulation part 10. The telephone line 6 is for transmitting a sound signal and has only a band of 300-3,400Hz. However, by switches 4 and 12, the line is switched for processing of a sound signal and that of a picture signal; therefore installation of a communications channel for a picture is unnecessary and the switching use allows transmission of a picture.
