Title: Extracting device of external shape data on figure
Inventor: YAMAMURA TATSUO
IPC: G06K9/46
Filed: 1983-07-22
Abstract: PURPOSE:To discriminate an external shape efficiently without any complex operation by extracting only an external shape data regardless of an internal pattern. CONSTITUTION:When a normal vertical scan is started, an A/D conversion part 7 outputs a binary-coded signal indicating that only the background is present (all-''1''), a connectivity detection part 20 outputs a connection presence/absence signal 20a indicating ''no connection'', and the writing to a background line data memory 26 is inhibited. Then, a horizontal scan on the horizontal lines of the binary-coded image is started. When a current scan is made on a horizontal scanning line, run numbers ''1'' and ''1'' are written in a run number memory 10 as a current scanning run number 24 at respective read end part of two background runs on the scanning line with a connection presence/absence signal 20a showing the ''presence of connection''.

Title: Optical space transmitter
Inventor: IGUCHI KAZUO
IPC: H04B10/116
Filed: 1984-06-30
Abstract: PURPOSE:To detect easily collision of transmission while eliminating nutual cancellation of subcarriers even when plural optical transmitters transmit optical signals at the same time by making a detected subcarrier n-time or 1/n-time. CONSTITUTION:A transmission data fed to a modulator 15 via an interface section 17 from a terminal device 20 is modulated by the subcarrier made n-time or divided into 1/n in frequency by a multiplier/frequency divider circuit 14 and the result is fed to an electrooptic converting section 16. Thus, the optical signal converted into an optical signal by the converting section 16 and transmitted toward a transmission/reception section 1 of a main optical space transmitter is synchronized with the phase of the subcarrier of the optical signal from the transmission/reception section 1 and modulated by the subcarrier same in frequency and phase with those of the subcarrier of the optical signal transmitted from the other optical space transmitter and even if collision of transmission takes place, the subcarriers are not cancelled together.

Title: Data communication control equipment
Inventor: FUKUTOME NAOFUMI
IPC: H04L29/08
Filed: 1986-06-10
Abstract: PURPOSE:To prevent a drop in transmission efficiency in the case of the increased processing quantity of information in CPU by controlling communication speed according to the processing quantity of information in a communication terminal equipment. CONSTITUTION:As for CPU 4 in the communication terminal equipment if its own quantity of information exceeds the prescribed value, the CPU 4 slows down its own communication speed. If said quantity is less than the prescribed value, the CPU 4 restores the speed. For changing the communication speed in such a way, an escape sequence is transmitted to a communication line terminal equipment 2 and a one on the opposite side, and instructions as to the modification of the communication speed are given. Thus the sudden stop of communications is hardly occurred even if the processing quantity of CPU 4 becomes critical.

IPC: H04N5/369
Filed: 1988-06-02
Abstract: PURPOSE:To realize a rapid read scanning speed by making an element area or a photoelectric transfer element smaller than a picture element area. CONSTITUTION:A first electrode 1 consisting of Cr, a semiconductor material 2 consisting of a-Si:H, and a second electrode 3 consisting of a transparent conductive film such as I.T.O are successively laminated. A region whereon the three layers are laminated functions as a charge storage type photoelectric transfer element. Therefore, an element area SS of the photoelectric transfer element is formed as the first electrode 1, and an actual element area SS is made smaller than a picture element area Sp by forming a defective section D at the first electrode 1. A time constant at read and reset can be thereby reduced, thus improving a read scanning speed.

Filed: 1980-09-29
Abstract: PURPOSE: To obtain a drum that withstands high coiling force and does not cause segment mark by providing a device that expands a segment of a coil winding drum divided into plural sections and wedges that fix the segment to the direction of diameter.  
     CONSTITUTION: When a piston united to an axis 25 of winding drum is moved to the left in axial direction by supplying pressurized oil to the cylinder, the axis 25 of the winding drum moves to the left. Consequently, the segment 21 which is in wedge-like contact with the axis 25 of winding drum expands in radial direction. On the other hand, when the piston moves to the left in axial direction, a rod 29 united to the piston, a connector 30 and a lower wedge 27 move to the left. In consequence, an upper wedge 28 which is in wedge-like connection with the lower wedge 27 expands in radial direction and push the upper wedge against a gap at the end face of adjoining segment 21. Accordingly, the segment 21 and upper wedge 28 from an even, truly circular drum and prevents generation of segment marks.

When the bar stock P is further ascendingly transported and approaches the roll 11, the middle part in the width direction is brought into contact with the peripheral surface of the roll 11 and, after that, both the side parts are brought into contact with the peripheral surface of the roll 11. In this way, the whole in the width direction of the bar stock P is brought into contact with the peripheral surface of the roll 11, the bar stock is mades to change its direction in a horizontal direction and transported to other place.

Title: Method for impressing magnetic field in continuous casting of double-layered cast billet
Inventor: KISHIDA YUTAKA
IPC: B22D11/04
Filed: 1993-05-14
Abstract: PURPOSE:To manufacture a cast billet having a superior separability of two layers by impressing a static magnetic field with the optimum impressing intensity and impressing direction in connection with the density of the two layers, electric conductivity and the size of a casting mold. CONSTITUTION:A static magnetic field with 80-150% of the magnetic intensity is impressed in which the growth rate of the displacement of two-layer interface is minimum that is obtained by a dispersion relational formula of Rayleigh- Taylor instability. The impressing direction for the static magnetic field is the direction either orthogonally crossing the short side of the cast billet 2 or perpendicular to the cast billet 2. Compared to the method for impressing a magnetic field with the long side of a cast billet orthogonally crossed, the cast billet with the two layers separated is satisfactorily manufactured by a small magnetic field intensity.
