IPC: H04N1/19
Filed: 1994-02-22
Abstract: PURPOSE:To provide a color line sensor camera, in which the resolution of color and position is excellent, and miniaturization and light weight configuration are facilitated. CONSTITUTION:A drive shaft 6a of a stepping motor 8 is coaxial to a shaft of a octal prism optical bandpass filter 2. A lens 4 receives an object light emitted from an object 9 and forms the image of the object 9 onto a line sensor 5. The optical bandpass filter 2 is made up of flat filters 2a-2h, and the transparent wavelength band of the filters 2a-2h differs from each other. A picture by one horizontal scanning line is generated by the line sensor 5. A galvanometer 1 drives a reflecting mirror 1c intermittently to scan an object image on the line sensor 5 in a direction orthogonal to a lengthwise direction of the line sensor 5. While the angle of the reflecting mirror 1c is advanced by one horizontal scanning line interval, the stepping motor 6 advances intermittently the optical bandpass filter 2 by 2pi/8 radian each to separate the object light by one horizontal scanning line into 8 colors.

Title: Digital relay unit for fault locating signal of transmission line
Inventor: NEMOTO KOJI
IPC: H04L25/02
Filed: 1992-02-12
Abstract: PURPOSE:To realize digital relaying and transmission of fault locating signal of transmission line between two communication networks having different clock frequency sources. CONSTITUTION:A transmission line fault locating signal inputted to a terminal 100 from a communication network A is written into a buffer memory 4 according to a clock A inputted to a terminal 200. A signal state change detecting circuit 2 detects variation of locating signal information and delivers thus detected variation to a phase control circuit 3. A phase comparing circuit 1 monitors the frequency difference between the clock A and a clock B inputted to a terminal 400 and delivers phase control information to the phase control circuit 3. The phase control circuit 3 processes the variation information fed from the signal state change detecting circuit 2 and information fed from the phase comparing circuit 1 and then produces a read out clock for a buffer memory circuit 4 for absorbing the phase difference between the clocks A and B at a position where there is no variation point of transmission line fault locating signal. Data signal is read out again according to thus produced read out clock and thus read out data signal is relayed and transmitted to other communication network B.
