Title: Digital-analog converter
Inventor: KANEKO YOSHIO
IPC: H03M1/66
Filed: 1987-04-23
Abstract: PURPOSE:To improve the resolution of digital/analog converting operation by varying a minimum output voltage in response to the change in a reference current so as to vary the digital/analog conversion output proportionally to the reference current. CONSTITUTION:Since a positive reference terminal Vr+ of a digital/analog conversion section 1 receiving an 8-bit digital data D' (0-255) is at a ground level, the reference current Ir is expressed in equation 1. Moreover, an output current of an arithmetic amplifier 2 is expressed in equation 2 and its output voltage Vout is expressed in equation 3, that is, equation 4. With a reference voltage Vin given as V1, the output voltage range of the digital data D'=255 is A and the output voltage of the digital data D'=80 is Va. If the reference voltage Vin changes to V2 due to external disturbance, the range of the output voltage Vout is B and the output voltage is Vb. Thus, the resolution in the conversion is improved.

Title: Exhaust gas efficiency promoting device
Inventor: MISHINA TAKASHI
IPC: F01N13/20
Filed: 1990-04-16
Abstract: PURPOSE:To exhaust an exhaust gas efficiently by the driving wind by enlarging the wind striking area through a widened exhaust port for exhaust gas of internal combustion engine, and enabling the exhaust port to receive wind equally through its entire area through a short cylindrical fine mesh formed thereon. CONSTITUTION:In an internal combustion engine an exhaust gas is exhausted by an energy obtained by its combustion, but the level enough to draw out the exhaust gas efficiently is not attained because the gas goes through the place where there is an exhaust resistance by an exhaust gas purifier or a muffler A. To cope with this an exhaust port B of the internal combustion engine is widened and the wind striking area is enlarged with an angle. Also, a short cylindrical fine mesh C is formed on the exhaust port B so that it may receive wind equally through the entire area. The exhaust gas is efficiently exhausted by the wind obtained by a speed by a car, or the like. It is thereby possible to raise combustion efficiency, and further attain an improvement of gas fuel expense saving, elevation of output and purification of the exhaust gas.

Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To easily understandably express the contents of a dynamic image file by one sheet of still images by extracting the images of a large change amount from the plural images for a specified number, reducing them, synthesizing them to one image and turning it to the first frame of a digital dynamic image file. SOLUTION: The number of frames to be extracted is inputted from a keyboard 5 and data for one frame are read from the dynamic image file composed of the plural frames in an auxiliary storage device 4 to a RAM 3. They are compared with the data of a previous frame and the change amount ΔD is obtained. An operation table to which the one whose change amount from the previous frame is large among the checked plural frames is inputted is searched by the ΔD. Whether or not the frame of the change amount smaller than the ΔD is registered inside the operation table is checked. At the time of YES, the frame whose change amount is smallest from the ΔD inside the operation table is eliminated and present frame information is registered.  The still images are reduced to a prescribed size corresponding to the extracted frame number and the respective frame data are synthesized and inserted to the head of the dynamic image file.

Inventor: KOBAYASHI TATSUYA
IPC: B41J29/00
Filed: 1993-04-27
Abstract: PURPOSE:To provide an image forming device having stable environmental characteristic at a low cost by transmitting reference frequency from an engine controller to a high voltage power source impressing bias on an electrostatic charging member. CONSTITUTION:The engine controller 100 consisting of a CPU, a ROM, a RAM, a clock generation circuit, a motor control circuit, a heater temperature regulation control circuit, and an image control circuit transmits the reference frequency equivalent to the frequency of AC electric field impressed on an electrostatic charging roller 2 to the high voltage power source 201. The high voltage power source 201 to which the reference frequency is transmitted impresses the bias obtained by superposing the AC electric field in accordance with the reference frequency on DC voltage on the core bar 21 of the roller 2. The AC electric field is controlled in terms of constant- current, and a photosensitive drum 1 is uniformly electrostatically charged by the roller 2 on which the bias is impressed. Therefore, a transmission circuit need not be set in the high voltage power source, so that the image forming device whose cost is low can be provided. Also, the electrostatic charging having the stable environmental characteristic can be performed by stabilizing the frequency.
