Title: Phase pulse signal transmitting circuit
Inventor: ARAI YUKIO
IPC: H04B3/56
Filed: 1983-01-10
Abstract: PURPOSE:To stabilize the generation of plural phase pulses by setting characteristic values between capacitors and impedance elements of a charging and an injection circuit larger than the on time of an electronic switch and smaller than an interval of transmission. CONSTITUTION:The charging circuit 4 and injection circuit 8 are connected together by a resistance 9 where a direct current flows. Then, the time constant of the capacitor 3 and resistance 9 of the charging circuit 4 is made far larger than the on time of the electronic switch 7 of the injection circuit 8, and the time constant of the capacitor 5 and resistance 9 of the injection circuit 8 is made smaller than the transmission interval of phase pulses. Therefore, even when the electronic switch 7 is turned on, the charging voltage of the capacitor 3 does not drop greatly. Consequently, even when the phase pulses are generated at short intervals, the capacitor 5 is charged to the same level and the level of the phase pulses is invariably stable.

Title: Optical reader
Inventor: MINE KAZUNORI
IPC: H04N1/19
Filed: 1988-01-08
Abstract: PURPOSE:To clearly read a white line image in a wide black area by forming a casing so that it provides an optical path in a specific length having light- shielding walls that protrude from the both sides of a slit in order to limit the width of transmitting light beam and thus trimming the shape of the light beam. CONSTITUTION:On the upper surface of the casing 3, the optical path 13 in specific length having the light shielding walls 12 that face to each other protruding from the both sides of the slit 10 toward an original is formed. The optical path 13 is so tapered that its sectional area comes the wider the lower its position is. A light beam radiated from a light source 4 and reflected on the original 2 transmits through the optical path 13, is reflected by mirrors 5, 6, 7, and condensed by a condensing lens 8 to be formed as an image by an image sensor 9. During said process, the reflecting beam from the original 2 is limited of its width by the optical path 13 and at the same time its shape is made trimmed. Therefore, the influence of reflection factor immediately before and after a read line is made less, hence a white line image in a wide black area can be read clearly.

Filed: 1991-01-14
Abstract: PURPOSE:To print image data in a limited memory size by comparing calculated memory capacity with detected remaining memory capacity and changing the output of the printer to monochrome corresponding to the capacity of a memory. CONSTITUTION:A CPU 3 uses a RAM 7 as a work area and calculates the memory capacity required for storing the input image data. On the other hand, the CPU 3 detects the remaining capacity of a frame memory 7b required for storing the printing data of the RAM 7 and compares the detected remaining memory capacity with the calculated memory capacity. Then, according to a color output flag 7a and the memory 7b, it is decided whether a color picture to be inputted is printed with colors or monochrome. Corresponding to the capacity of the memory 7b, the color image data to be inputted is converted to the image data of monochrome. Thus, the image data requiring the large capacity memory can be printed in the limited memory size.
