Abstract: PURPOSE:To obtain a sharp image even in special reproduction by generating horizontal synchronizing pulses and vertical synchronizing pulses by a synchronism processing circuit, and taking a field detection signal and a playback signal for timing control from the output relation between those synchronizing pulses and driving active matrix LCD cells. CONSTITUTION:The synchronism separating circuit 2 of the synchronism processing circuit 1 separates a horizontal synchronizing signal and a vertical synchronizing signal and the D type flip-flop 1 of a field detecting circuit 7 inputs the horizontal synchronizing pulses at its D input terminal and the vertical synchronizing pulses (a) at its CK pulse input terminal. A special playback signal generating circuit 8 inputs a Q output (b) and a (Q) output (c) to an X-OR gate U3 and an output (d) becomes H. A NAND gate U7 inputs the L signal inverted by an inverter 6 to enter a closed state and the NAND gate U7 is opened; and a NAND gate U5 outputs a pulse signal (f) and the active matrix LCD cells are driven alternately to obtain the sharp image.

Abstract: PURPOSE:To enhance the process contents of a microcomputer for a robot-controlled interpolation circuit that performs an interpolation of a straight line or a circular arc with the tip of a torch, by storing the distribution data in each pulse distributor and then using this data as a data output when convenient for the computer. CONSTITUTION:The pulse distributors 10 and 13 deliver the X axis command pulse PX and the Y axis command pulse PY, counts the pulses PC supplied from the oscillator 16 and then delivers evenly the pulses PX and PY in the number designated by  the registers 11 and 14 until an overflow starts. Then the registers 11-15 set the X  and Y components DELTAX and DELTAY of the segment to receive a linear interpolation, and  the data following the data that are set to the registers 11 and 14 is set at the registers 12 and 15 each. At the same time, the registers 17 and 18 set the data Df to  decide the oscillation frequency of the oscillator 16. Then the data Df varies the oscillation frequency of the oscillator 16 in accordance with the length of the segment  to be interpolated. Thus the torch speed can always be set at a constant level.

Abstract: PURPOSE:To enhance the quality of picture by an ink jet plotter by printing a letter in diagonal dots upon forward moving of a carriage and the residual dots upon backward moving of the carriage to eliminate the strain of the dots due to the integration of adjacent dots. CONSTITUTION:The content of one line shift register 10 is alternatively applied at the data of odd address to an upper 20 shift register 11 and at the data of even address to a lower 20 shift register 12 with a D flip-flop 13 by a data clock CLK. After this operation is repeated to fully load the registers 11, 12, a carriage is moved in one direction. When a forward signal becomes high level, an AND gate 14 is opened to feed the content of the register 11 to a switching circuit 16 to print a letter in diagonal dots as disignated with white small circles. When the carriage is fed to the end, the forward signal becomes low level and a return signal becomes high level. Thus, the carriage is moved in opposite direction and an AND gate 15 is opened to feed the content of the register 12 to the switching circuit 16 to print the letter in the residual diagonal dots as designated with black small circles.

Title: Electrophotographic device
Inventor: YAMAGUCHI YASUKI
IPC: B41J2/44
Filed: 1990-01-31
Abstract: PURPOSE:To exchange an image carrier with high frequency of exchange by forming slits on both sides of a supporting body which supports an exposure part and is loaded freely attached to / detached from a main body and forming shaft holes in these slits to which both edges of shaft parts of an image carrier are engaged. CONSTITUTION:When the image carrier 14 is exchanged, a connector 36 is removed, and the image carrier unit 18 is taken out upper ward in a state where a hook 48 and a shaft part 41 of the image carrier 14 are engaged together. At this time, slits 43 are widened and the shaft parts 41 are allowed to fall from a shaft holes 42 by the supporting body 18a. That is, the image carrier 14 is separated from the supporting body 18a and remains on a frame 45. Following this, by removing the hook 48 from the shaft part 41, only the image carrier 14 with a high frequency of exchange is removed from the frame 45 and disposed as a single unit. Furthermore, since a drum 52 and a flange can be separated by extracting the shaft part 41, the image carrier 14 removed from the supporting body 18a can have only the deteriorated drum 52 exchanged. Thus the running cost can be greatly decreased.

Filed: 1980-02-21
Abstract: PURPOSE:To make possible continuous flow of opration without semifinished products being stuck by heating a rotary auger for perforation at temperature for melting a foam and piercing a hole in a hot foam right after manufacture. CONSTITUTION:During the hot state without cooling of synthetic resin foam mainly based on polyethylene, poly PVC and their copolymer which can be softened and molten by heating right after manufacture, a rotary auger for perforation is heated at foam melting temperature and perforation is carried out, so that continuous flow of operation is enabled. The auger used here is a round bar of 6mm. in diameter with a cone-shaped nose 1, and a tapered center 2 measuring 5mm. and further with one mm.-deep ''V'' letter-shaped groove 3, 3' running provided at two spots from the nose to the center on the surface in parallel with an axial direction. Under this constitution, the hole surface presents the same condition as if it were pierced in a foam. Because of a thin center, scraps can easily be discharged and a 6mm.-hole having no difference between the inlet of an auger and the diameter of a hole diameter can be opened.

Title: Signal delay device
Inventor: KANEKO TADASHI
IPC: H03K5/13
Filed: 1985-02-06
Abstract: PURPOSE:To output a delay pulse having less variance in delay time even when it is large by obtaining the delay pulse whose time does not exceed T from a clock having a time width T and triggering an FF at the trailing edge of the said pulse so as to obtain the delay pulse having a time T or over. CONSTITUTION:When a signal having a pulse width T is impressed to a terminal 1 and a start signal is impressed to a terminal 72, an output of a prescribed phase appears at each output terminal of a counter circuit 71, further output terminals (a-f) giving outputs with different delay time from the delay circuit 2 are selected and a delay signal from the terminal (a) is inputted to a clock terminal CL of an FF61 via an inverse circuit 51. When the signal from the terminal (a) falls since a J input of the FF61 goes to H by an output 1 of the counter circuit, the FF61 is inverted and the level of an output 31 goes to H. Then the signal at the terminal (a) falls again when outputs 1, 2 of the counter circuit go to L, H, and then the FF61 is inverted and the output 31 goes to L. This is applied also to output terminals 33, 32.

Title: File re-formation system
Inventor: ONO YUJI
IPC: G06F12/00
Filed: 1990-01-30
Abstract: PURPOSE:To enable file re-formation from a judgement of whether a file needs to be re-formed or not to file re-formation without any operator's intervention and to prevent an operator from making a misjudgement in the file re-formation by providing a condition setting means and a medium control file and only setting the conditions of the re-formation of a sequential access storage medium. CONSTITUTION:A file storage state monitoring means 5 calculates the ratio of the sum of the sizes of unnecessary files to the capacity of sequential access storage media 7 and 8. Assuming files F2 and F3 to be unnecessary, it is decided that file re-formation is required when the ratio of the sum of their sizes exceeds the area use rate of the unnecessary files which is set by the condition setting means 2. Then an unnecessary file discarding means 6 copies the files F1 and F4 from the sequential access storage medium 7 whose files need to be re-formed to the other medium 8. Lastly, the means 6 copies the file F1 and F2 from the medium 8 where the files F1 and F4 are copied to the sequential access medium 7 in order from the beginning. Consequently, the sequential access media 7 and 8 having the files F1-F4 stored come to have the files F1 and F4 stored.
