Title: Pdpc receiving system
Inventor: OOSATO TATSUO
IPC: G01S15/86
Filed: 1983-03-07
Abstract: PURPOSE:To remove mutual interference in the simultaneous operation of a sonar, radar or the like by making a delay element corresponding to a filter bank programmable. CONSTITUTION:A received signal filtered with a filter bank 1 comprising a BPF is converted into energy with an energy detector 2. The energy is delayed with a delay time programmable delay element 3 according to a delay time program of a delay time program supply controller 5. An adder 4 adds up output of the element 3 to obtain an output close to a matching filter. Thus, the mutual interference of a sonar or the like can be prevented without changing the bank 1.

Title: Picture communication equipment
Inventor: KUSAO HIROSHI
IPC: H04N7/14
Filed: 1991-03-01
Abstract: PURPOSE:To obtain a still picture with high picture quality by devising the use of two field memories provided for moving picture transmission. CONSTITUTION:A TV camera converts a video image into an electric signal and outputs the electric signal to an A/D converter 2. A memory control section 7 receives a signal representing whether the output picture signal is in an odd number field or an even number field. A selector 5 connects field memories 3, 4 selectively to a coder 6. In the case of still picture transmission, the field memories 3, 4 are used differently from that in the case of moving picture transmission. That is, an odd number field picture of the field memory 3 is coded and sent and then an even number field picture is coded and sent. Since only the odd number field picture is received at a receiver side, high picture quality is not obtained at this point of time, but the high picture quality is obtained from the picture as the even number field picture is being received. High picture quality is obtained without increasing number of memories.

Abstract: PROBLEM TO BE SOLVED: To detect overheating at each part of a belt conveyor reliably at low cost by driving the belt conveyor at a desired speed at a specified time when it is not operated thereby monitoring the conveyor entirely at all times. SOLUTION: An infrared radiation thermometer 2 and the like are arranged on a belt conveyor 1 and the temperature thereof is measured. When the measurement of thermometer 2 is higher than a preset abnormal temperature 8, an alarm 9 is actuated. An operation decision unit 11 monitors an operation signal 10 and actuates a timer 12 when the belt conveyor is not operating such that the conveyor 1 is turned through a drive circuit 14 for a motor 13 at a predetermined time interval. An overheated part 4 generated during operation of stoppage of conveyor causes local temperature rise of belt and since the local hot spot passes through the field 3 of thermometer 2 as the belt turns, the hot spot 4 can be detected. Hot spot 4 generated during operation conveyor can be detected in early stage by temporarily stopping the operation of conveyor 1 intentionally and then turning the conveyor again.
