Title: Contact type sensor
Inventor: YAMASHITA RIICHIRO
IPC: G01V9/00
Filed: 1993-02-12
Abstract: PURPOSE:To retain air in internal space to atmospheric pressure and to secure the insulation spacing of a contact for preventing erroneous operation by releasing the internal space of a sensor body to atmosphere via a continuity path. CONSTITUTION:Lead wires 17 and 18 which are led from the edge part of a sensor body 11 consisting of an insulation elastic body such as rubber is covered with a coating tube 20 and an air continuity path 21 consisting of a capillary is formed inside the tube 20. When a vehicle, etc., are on the sensor and crushes the body 11, both contacts 13 and 14 contact and current flows to the lead wires 17 and 18. It is detected, thus detecting the presence of the vehicle etc. In this case, when the body 11 is compressed and deformed, an internal space 12 contracts and air pressure increases. The air pressure is allowed to escape to the open air via the air continuity path 21. Then, when the load of the sensor is released and the body 11 is subjected to elastic return, the space 12 expands and the open air flows in from the path 21, the space 12 is maintained to be at the atmospheric pressure, and hence the insulation spacing between the contacts 13 and 14 is secured, thus eliminating the reduction in internal pressure due to oxygen absorption and gas transmission and preventing an unexpected short-circuiting.

IPC: H04N19/60
Filed: 1993-02-12
Abstract: PURPOSE:To minimize the disturbance of a transmission picture due to the revision of a picture input source at a sender side without using an expensive system by detecting the fluctuation of a synchronizing signal of input picture information so as to compression-code an inter-frame difference based on a result of detection. CONSTITUTION:Picture element data of a current frame and picture element data at a concerned position of a preceding frame (prediction data) are inputted respectively to a subtractor section 101. The subtractor section 101 applies subtraction processing to them and outputs an inter-frame difference. A synchronizing signal monitor section 102 always monitors a picture synchronizing signal to be inputted and detects the fluctuation of the synchronizing signal, then the section 102 sends a zero output selection signal. A prediction error selection section 103 normally outputs the inter-frame difference being an output of the subtractor section 101 to an orthogonal transformation section of a post-stage. When the zero output selection signal is received, the section 103 stops the output of the inter-frame difference and outputs zero instead.
