IPC: H04N5/68
Filed: 1986-06-05
Abstract: PURPOSE:To reduce power consumption and prevent a variation in electron radient quantity and shortening of life due to temperature increase by driving a cold negative electrode type cathode with pulse voltage. CONSTITUTION:A cold negative electrode type cathode 1 driven with pulse voltage by a driving power supply 3 is arranged at the rear end of a glass tube 2. And, the cathode 1 is driven by means of pulse voltage impressed thereto with the power supply 3. Then, electrons are generated periodically from the cathode 1 for 25s a time in 500ns for example and displayed by a modulating electrode 5, a deflecting electrode 6 and a face plate 4. As a result, heat generation of the cathode 1 becomes approximately 5%, with little heating caused, of the one generated when constant voltage is impressed.

Filed: 1986-06-04
Abstract: PURPOSE:To increase the processing speed of a substitute memory area by providing a substitute memory area which is designated by a main memory when an error occurs in a memory area where the data stored in an auxiliary memory device is written. CONSTITUTION:If a CPU 1 detects an error while data are transferred to a memory area 5 from the CPU 1 to write data to an auxiliary memory device 3, the CPU 1 first discontinues the transfer of data and reads the information on a substitute memory area 4 stored on a main memory 2 at a high speed to detect that the substitute area is equal to a memory area 6 at and after an address (A+m+1). Then the CPU 1 transfers data to the area 6 of the device 3 and writes them there. The CPU 1 detects the final address (A+B) of the area 6 storing data and writes fast a fact that the next substitute memory area is equal to a memory area 7 set at and after an address (A+B+1) after addition of 1 to a self-substitute information memory area 4 with replacement.

Title: Automatic original feeder
Inventor: NAGASAWA KIYOTO
IPC: G03G15/04
Filed: 1977-10-28
Abstract: PURPOSE: To achieve the prevention of occurrence of mis copying, jam mode, etc. owing to mis-insertion and mis-alignment of originals by starting conveying and copying motions of the original only when the original has been inserted.  
     CONSTITUTION: When no original is inserted and a microswithch 1 is OFF, the output of an inverter 5 becomes low potential and a NAND circuit 22 cuts off the fall pulse from a differentiation circuit consisting of a capacitor 10 and resistance 11. Hence, a start signal is generated only when the insertion of the original is checked with the circuit 22. An insertion control circit 23, upon receiving of this start signal, drives an inlet solenoid 24 and motor 25, thereby stopping the original in the exposure position on the original base of the main unit of the copying machine and at the same time causing the copying motion to be started.After this, a discharge control circuit 28 upon receiving of the discharge signal owing to the exposure completion of the original and end of its copying turns ON an outlet solenoid 29, causing discharge motion to be accomplished. Thereby, mis-copying, jam mode, etc. owing to mis-insertion and mis-aligngment of the originals may be prevented.

Abstract: PURPOSE:To make displacement information extending over a wide range detectable so accurately in getting a high resolution even at a low frequency domain by inputting a sine wave signal and a cosine wave signal into two comparators and an integral type analog-to-digital converter, and adding the output thereto. CONSTITUTION:Two comparators 13 and 14 detect a time range between a sine wave signal (a) based on displacement (position) information and a zero-cross point of a cosine wave signal, outputting a double waveform frequency signal (c) from an XOR circuit 15. An integrating means 16 counts pulse numbers of the signal (c), and resolution outputs a 1/4 periodic signal (d) of these signals (a) and (b). This signal (d) is not varied as far as both these signals (a) and (b) are not varied at the 1/4 period. integrating type analog-to-digital converters 18 and 19 measures these signals (a) and (b) into a high resolution through a voltage level, but when these signals (a) and (b) are not changed as long as the 1/4 period within the specified time, so far as during the while yet smaller signal is outputted from an adding means 21 by means of a digital signal (position information) to be outputted from a signal processing circuit 20 by control over a connecting means 17, so displacement information on a moving body is detectable at a high resolution.

Abstract: PURPOSE:To make low the cost and small the size, by taking all the weight element values as two values, +1 and -1, in N types of irregular signal generators, which have no correlation and in which the state of a n-stage shift register transferred with binary random numbers is added with weight by each weight vector. CONSTITUTION:The state of the n-stage shift register 2 to which the binary random numbers from a simple random number source 1 are transferred, is added with weight at the weight vector W<k>=(W1<k>, W2<k>,...,Wn<k>) to produce the irregular signal of the normal distribution. In this generating method, N units of weight vectors W<1>, W<2>,...,WN shown in equation I, orthogonal to each other, are connected in parallel with the n-stage shift register 2, and weight addition 3 is made with relevant weight vector to simultaneously produce the irregular signal of N types normal distributions without correlativity with each other. In this case, the weight vectors are used, in which the element value of the weight vector at an arbitrary value K takes two values of +1 or -1, and the self-correlativity function shown in equation (II) is zero at j 0.
