Title: Graphic generator
Inventor: YOSHIDA JUN
IPC: G06T11/00
Filed: 1986-02-26
Abstract: PURPOSE:To quickly generate a multicolored picture approximate to a real one by generating a painted-out graphic in a picture memory based on the contents of a graphic memory. CONSTITUTION:A picture drawing part 1 generates a graphic in the graphic memory 2 as a figure (a) illustrates, and a drawn picture element and non-drawn picture element are stored '1' and '0', respectively, in the memory 2. An edge detection part 3 sequentially reads picture elements in the memory 2 at the beginning shown by arrows in the figure (a), and repeats the reading until '1' to show the edge part is detected. Simultaneously a write control part 5 writes color data stored in a color data register 4 in a picture memory 6 shown by arrows in the figure (b) while the detection part 3 is reading the color data. In that case, the memory 2 and the large capacity memory 6 are separated, and the former uses one bit per picture element, whereby the memory 2 can be quickly read in order to detect the edge.

IPC: H04M17/00
Filed: 1982-03-15
Abstract: PURPOSE:To apply the system to both coin pre-deposition and post-deposition systems, by opening a DC loop to a main trunk for monitor, after the information is transmitted to a dialed address, when no charging signal is incoming for  a prescribed time after automatic dialing. CONSTITUTION:If off-hook or removal of cash box is performed, a contact (gs) of a relay controlling circuit 50 is closed in response to the operation of a hook switch SW40 or a cash box SW100, a DC loop to the main trunk is closed. A CPU20 performs self-diagnosis and executes the automatic dialing, then the CPU22 waits for the response of a called party and discriminates whether or not the charging signal is received. When the exchange is the pre-deposition system, the charging signal is incoming immediately through the response of the called party. When the exchange is the post-deposition system, since the imposition signal is incoming in response to the opened DC loop after the response of the called party, after waiting for a prescribed time, a forced cutoff circuit 14 is controlled and the loop opening for a prescribed time is done and the reception of the charging signal is waited. When no charging signal is incoming, the automatic dialing, the transmission of information and the opening of the DC loop are repeated for five times.

Abstract: PROBLEM TO BE SOLVED: To enable displaying an image without burning it regardless of a display pattern even when a video of an interlaced scanning system is displayed on a liquid crystal display by further inverting a polarity at every prescribed cycle of a prescribed period and applying a voltage to a liquid crystal and a material. SOLUTION: A frequency division circuit 109 generates a field inversion signal PR taking exclusive ORing between a polarity inversion signal FR and the signal several frequency dividing a vertical synchronizing signal VS to output it to a polarity inversion circuit 103. The field inversion signal PR inverts the polarities of an oddnumbered field and an even numbered field each other for the prescribed cycle, e.g. for the prescribed period at ever two frames. The polarity inversion circuit 103 inverts the polarities of image signals RGB around certain reference potential at every field and two frames corresponding to the field inversion signal PR. In such a manner, the polarity at every prescribed period in the prescribed cycle at every prescribed cycle of the prescribed period is inverter further, and the voltage is applied to the liquid crystal material.

Abstract: PURPOSE:To secure an intraoffice communication even in case the transmission line has some fault, by connecting the subscribers within the own office via the intraoffice folding connection DC cut-off capacitor and with no passing through transmission line between the own office and the master station. CONSTITUTION:In case both the transmission lines HwO and Hw1 connecting to the master station CO become faulty, the intraoffice folding change-over relay R works. Then the working contacts r0 and r1 are connected to the side of the DC cut-off capacitor C to ensure a connection between the two subscriber trunks LCT0 and LCT1. Thus a route is formed to connect the intraoffice outgoing/incoming subscribers with no passing through the transmission line Hw, i.e., the route of originating subscriber SUBO-space-division line concentration network SD-subscriber trunk LCTO-intraoffice folding connection DC cut-off capacitor C-subscriber trunk LCT1- network SD-incoming subscriber SUB1. Thus a talking is possible between the two subscribers within the own office.

Abstract: PROBLEM TO BE SOLVED: To accurately measure the threading speed of a steel strip and to surely detect the slip of plural bridle rolls in a tension bridle device which is installed on lines for rolling, pickling, surface treatment or the like of a steel strip. SOLUTION: A threading speed measuring device 6 having a ascendable and descendable threading speed measuring roll 7 bodies the bridle rolls 2-2 to 2-4 which are the measuring object of the tension bridle device 1 and, by changing the angle θ of contact of the steel strip S with the roll 7 in accordance with the conditions of the steel strip, the slip between the roll 7 and the steel strips S is prevented. After the accurate measurement of the threading speed is made possible, the threading speed V0 of the steel strip is determined from the number of rotation and diameter of the roll 7, the circumferential speed Vi (i=1, 2, 3, 4) of each bridle roll 2-1 to 2-4 is determined from the number of rotation and diameter of the bridle roll.  When the threading speed V0 is compared with the circumferential speed vi (i=1, 2, 3, 4) of each bridle roll and the absolute value |V0 -Vi | becomes larger than a prescribed threshold Vth , it is judged that the slip is generated between the bridle roll and the steel strip.

Title: Detecting system on abnormality of absolute signal of absolute encoder
Inventor: SEKI SHINJI
IPC: G01D5/249
Filed: 1984-03-08
Abstract: PURPOSE:To detect the abnormality of an absolute signal, by adding incremental signals in one direction while subtracting incremental signals in the reverse direction, and by determining the result of these operations. CONSTITUTION:When an incremental signal P is inputted from an OR circuit G3 after an absolute signal A is inputted to an input end D of FFF1, a counter C count the signal P to be added. When the input of the signal A is discontinued, the count value of the counter C is stored in a latch circuit R.

Title: Malfunction preventive circuit
Inventor: ISOTANI HIROSHI
IPC: G01D5/12
Filed: 1978-04-11
Abstract: PURPOSE: To eliminate input signal superposed with noise, by comparing the sampled input signal and the input singnal after storing, and controlling the hold of input signal through sequence control.  
     CONSTITUTION: A stabilized input signal is sampled and stored in an analog memory 1. This stored value and the input signal in the subsequent specified period are compared in aboslute values by a comparator 3. When the subsequent input signal is less than the stored value, the output of AND gate 4 through the comparator 3 becomes low level, and latch circuit 5 does not provide latch operation, so that the input signal is outputted through a second analog memory 2. When noise is superposed in the input signal and the input signal becoms larger than the stored value, the input signal is latched by the circuit 5 due to inverting output of the gate 4, and is elimenated. This inverting output is, at the same time, applied to a sequence controller 7 to reset the gate 4, so that the measurement may be started again immediately without having to wait for the next period. As a result, the noise is completely eliminated, so that occurrence of malfunction due to noise may be prevented.
