Title: Pulse width converting device to be provided in integration type ad converter
Inventor: NAKAGAWA MICHIO
IPC: H03M1/52
Filed: 1980-01-16
Abstract: PURPOSE:To obtain a pulse width signal proportional to input data, by sending digital data of the output register of the integration type A/D converter to the preset counter and by counting this data until the clock pulse is counted up. CONSTITUTION:Analogue input 10 is converted to a digital data by the double integration type A/D converter and is latched by output register 40 and is sent to preset counter 50. Preset counter 50 counts clock pulses 2; and when the count value becomes maximum, counter 50 resets flip-flop 70 to stop output pulse 5. The time from preset to count-up is proportional to data of output register 40, namely, analogue input 10.

Title: Transmitting and receiving method and apparatus for digital encoded video image
Inventor: WITH PETER HENDRIK NELIS DE
IPC: H04N7/30
Filed: 1993-01-12
Abstract: PURPOSE: To obtain the method and system recording a video image with excellent image quality for reproduction at a higher speed by dividing an image into a plurality of blocks and specifying an image increment area for each block. CONSTITUTION: A first code word CW1-Bi of each data block DCT-Bi (i=1...N) is sent at first after a synchronizing code and then a 2nd code word CW2-Bi and a 3rd code word CW3-Bi of each block are sequentially sent. If a transmission error takes place, no code word succeeding to a next code word is recovered but the code word before the error is not affected. So long as no error takes place in the transmission of the 1st N code word, each 1st code word CW (that is, a DC level) of an optional block of a group at least is recovered. Thus, the image quality is more excellent than a conventional method not receiving blocks at all. As the occurrence of the error is slow, more detailed image of each block is reconfigured.

IPC: G03G15/01
Filed: 1988-01-12
Abstract: PURPOSE:To always obtain a correct image by estimating a surface potential curve caused by electrification and exposure, and making an optimum image forming condition by humidity, etc., variable. CONSTITUTION:The title device is formed by adding an environment sensor 19 to a conventional device. This environment sensor 19 is constituted of a temperature sensor and a humidity sensor, and provided on a position where moisture absorption of a toner in the vicinity of a toner hopper, in the vicinity of a developing device, etc. is reflected well. As for printing, under the same image forming condition, the density drops at a low humidity side, and the density is improved at a high humidity side, therefore, by detecting the humidity by the humidity sensor 19, a contrast potential corresponding to the humidity is derived, and based on its value, an image forming condition is set. In such a way, even if the environmental condition is fluctuated, a stable image is obtained, and also, since the printing density is different at each color in accordance with humidity, when the image forming condition is made variable at each color, the fluctuation of the image density caused by a difference of a color can also be corrected.

Abstract: PURPOSE:To quicken rising of lamp output in a photographic copying machine having manual exposure adjusting function by keeping the lamp current above a fixed value by an automatic exposure adjusting device only at the time of starting. CONSTITUTION:The value of voltage applied from a power source 31 to an exposure lamp 2 is known by rectifying voltage applied to a dummy-load circuit 33 which is equivalent to the lamp 2 by a waveform shaping circuit 34. A trigger pulse generating circuit 41 controls a thyristor 32 so that the sum of this and the value obtained by detecting reflected light from an original by a light detecting circuit 38 become equal to output of a reference voltage generating circuit 39, and lamp output is automatically adjusted to correspond to the density of the original. It is also possible to make manual adjusting by changing a switch 36 to a contact (b). However, as rising up is slow and amount of light is unstable if lamp current is small when lighting up of the lamp is started, the switch is kept to a contact (a) of automatic adjusting side during specified time determined by a timer.
