Title: Recording and reproducing device
Inventor: NISHIMOTO NAOMICHI
IPC: H04N9/81
Filed: 1983-10-31
Abstract: PURPOSE:To obtain a picture without lateral noises, etc., by absorbing a quantizing error when averaging the level of the reference level of a color difference signal which is added to a time-base compression color difference signal and recorded, and by adding the error to the preceeding part of a restored reproduction color difference signal. CONSTITUTION:After a luminance signal and a color difference signal of a color image signal are compressed in terms of time base, they are multiplied by time division, and recorded in a recording medium by modulation of frequency. A quantizing error absorbing circuit when averaging the digital signal level of the reference level signal of the color difference signal, which is added to the preceeding part of a time base compression color difference signal and recorded in the part at the time of reproduction, is inserted to R-Y and B-Y color difference signal systems from DA converters 18 and 37 in which a restored color difference signal having the time base extended is supplied. Switches 79 and 76 operate cooperatively. During the period of horizontal blanking, the switches 79 and 76 turn on, an achromatic level signal is grounded through capacitors C3 and C4, and a quantizing error is absorbed. In this way, a picture signal without lateral noises, etc., can be reproduced.

Title: Intermittent drive device
Inventor: TANAKA SOSUKE
IPC: F16H27/08
Filed: 1990-08-01
Abstract: PURPOSE:To thin a whole device which is accurate to change over and is not required to add a rotational force to promote engagement by providing a gear part and an outer peripheral cam part to engage with a partial gear part on each step of an engine gear. CONSTITUTION:When a master gear 1 rotates in the counterclockwise direction and an untoothed part of a first loading gear 2 runs on an outer peripheral cam part 11c of its first step, a second loading gear 3 engages with an output gear 8 and this second loading gear 3 stops rotating by braking from the mechanism side. Consequently, the first loading gear 2 causes a slippage of a small angle in the clockwise direction against the second loading gear 3, and accordingly, an elastic force is energized to a torsion spring 4. This energized elastic force turns the first loading gear in the direction to follow the master gear 1 when the master gear 1 rotates in the clockwise direction and is changed from the non-conductive state over to the conductive state, and it is quickly engaged with the first step.

Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a signal processor and a signal processing method by which an extracted image area can easily be recognized when outputting image signals obtained through high-speed scanning as video signals. SOLUTION: The video signals outputted from a CCD 2 having n-fold scanning speed in comparison with ordinary speed are received through a camera signal processing circuit 3 to an image extracting circuit 4. The image extracting circuit 4 extracts the image area within the range of 1/n from respective frame images related to the received video signals and outputs only the images in the extracted image area to a synthesizing circuit 5. The synthesizing circuit 5 synthesizes the received extracted images so as to two-dimensionally arrange (n) pieces of images. On the other hand, a character generator 8 outputs frame information showing the contour of the image area extracted by the image extracting circuit 4 to an adder 9. The adder 9 adds this frame information to the video signals thinned just for the number of frames by the camera signal processing circuit 3.  Together with the picked-up image, the frame showing the extracted image area is displayed on a finder 6.
