IPC: H04N5/64
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain the safe video observation device which is smallsized and high in definition and has small electromagnetic wave trouble by providing a fiber bundle for sending a linear light signal from a light source unit to a display unit. SOLUTION: The linear light signal is made incident on the optical fiber bundle 3 from its end surface 3a, guided to the display unit 4, and reproduced on an end surface 3b to form a linear image. The linear image is projected as a virtual image by an ocular 8 on a position of 1m to an infinite distance. Linear images which are projected in sequence are scanned by a galvanometer mirror 9 at right angles to the array direction of the linear images. The rotation of the galvanometer mirror 9 and the light emission of an LED array 6 are controlled by a control circuit 7 synchronously. A two-dimensional image is not projected actually at a time, but the scanning of the galvanometer mirror 9 is so fast that an observer can observe a twodimensional virtual image. The ocular 8 and galvanometer mirror 9 are constituted in the display unit 4.

Title: Transmission source identifying device and transmission source identifying method
Inventor: UEDA MAMORU
IPC: H04N21/236
Filed: 1995-03-24
Abstract: PURPOSE: To detect the switching of a signal on a reception side and to prevent the generation of a transmission error by the switching of the signal by looking at only the change of a transmission source identification code. CONSTITUTION: A transmission source identification code extraction circuit 3 extracts a transmission source identification codes 9 from the inside of the header of the SDDI format of a reception signal and supplies the codes to a previous transmission source identification code holding circuit 4 and a transmission source identification code comparison circuit 5. The circuit 5 compares the previous transmission source identification code 10 before one line that the circuit 3 latches and the code that the circuit 3 newly latches. When the codes 9 and 10 are not matched, the circuit 5 judges that a signal is switched and outputs a signal switch detection signal 11. Thus, because the change of the transmission source identification code 9 is detected and the switching of a transmission signal is detected, the switching of the transmission source can be detected by a line unit.

Abstract: PURPOSE:To enable contacts to come in contact with and part from each other more properly. CONSTITUTION:This device has a stationary contact 1 fixed to a stationary contact plate 2, and a movable contact 3 fastened in such a way as faced to the contact 1 on the forward end 4b of a movable contact plate 4 having a supported base end 4a. The contact surface 3a of the movable contact 3 comes in contact with and part from the contact surface 1a of the stationary contact 1 for open/close operation, when the movable contact plate 4 is actuated. The contact surface 1a of the contact 1 is formed to be higher at the side of the forward end 4b than at the side of the base end 4a of the movable contact plate 4, in order to have a slope for the fixed surface 2a of the plate 2. According to this construction, the contact surface 3a of the contact 3 first comes in contact with a forward end point P formed to be higher and, then, migrates to a base end point P so pressed as to maintain contact pressure. Thus, a travel amount during the motion becomes larger, and the contacts 1 and 3 can come in contact with and part from each other more properly.
