Title: Driving device for electrochromic display element
Inventor: ONISHI TORU
IPC: G09G3/19
Filed: 1988-08-08
Abstract: PURPOSE:To increase the response speed of a color change and to prolong the life of the electromagnetic element by providing a control part for quantity of electricity between a constant voltage power source and a switching means to prevent the overcurrent on the element. CONSTITUTION:The control part 30 for quantity of electricity which limits the quantity of electricity to 5mC/cm<2> is provided between the constant voltage power source 20 of 1.5V to the electrochromic display element (ECD) 10 and the switching means 40 which switches the polarity of the voltage impressed to the ECD 10. This control part is constituted of capacitors 31, 32 and diodes 33, 34. The ECD 10 attains required 1.2V after +1.5V, 5mC/cm<2> charge is implanted as the quantity of electricity at the time when the ECD 10 discolors from red to blue; therefore, the limitless high voltage is not impressed on the element and the life is prolonged. The voltage attains 0V after the biasing of -1.5V at the time of the change from blue to red and, therefore, the response speed is faster than mere short-circuiting of 1.2V.

Filed: 1990-07-28
Abstract: PURPOSE:To suppress the wasteful use of a storage area by specifying binary image data by a video signal supplied from a camera part, and performing an operation so as to store it in an internal storage area. CONSTITUTION:An image processing part 10 compares the binary image data stored in the storage areas Mi (i=1, 2, 3...m) of image memory 7 with the binary image data of one frame, and calculates the absolute value of data difference between two binary image data. The binary image data of background (no visitor exists) stored in frame memory 8 is compared with the binary image data including the background and the visitor, and the binary image data with the maximum difference area value Si is specified. Therefore, the image data in which the visitor is photographed extending over the widest range can be specified and stored in the image memory 7. Thereby, when the binary image data stored in the image memory 7 is reproduced afterwards via a reproducing part 4 and a reproducing video signal is displayed on a monitor 6 via a change-over switch 5, the visitor can be recognized more precisely.

Title: Rotary head type magnetic picture recording and reproducing device
Inventor: TACHIBANA SABURO
IPC: H04N5/783
Filed: 1985-09-10
Abstract: PURPOSE:To observe a desired still picture in a short time by varying the width or the cycle of the driving pulse in terms of time in a frame feed reproduction mode and therefore increasing the average driving speed of a magnetic tape in accordance with the lapse of time. CONSTITUTION:The switches 5 and 7 are changed to the sides of terminals (b) and (d) respectively in response to the push of a frame feed operating button in a frame feed reproduction mode. Then a switch 10 is turned on and a capstan drive circuit 3 is driven by the output of a pulse width varying circuit 8. For the circuit 8, the switch 10 is closed with push of the frame feed operating button and the output voltage of an integration circuit 11 rises up to a fixed level according to a prescribed time constant. Thus the degree of conduction of a transistor 12 is increased and the time constant of a monostable multivibrator increased and the time constant of a monostable multivibrator 16 is changed. Therefore the duty cycle of the output of the circuit 8 varies as the time elapses against the output A of a feed pulse generating circuit 4. Then the drive time of a capstan motor 6 is increased to increase the number of frames that are fed at a time.
