Title: Sequence control device
Inventor: KUMASAKA TATSUAKI
IPC: G05B19/05
Filed: 1979-10-15
Abstract: PURPOSE: To make it possible to select arbitrarily a holding type or nonholding type as the set state of an internal memory, by providing interlocking switches.  
     CONSTITUTION: If switches SW 1  and SW 2  are closed and opened respectively, the internal memory circuit is set to the holding type. That is, reset data DS for condition truth and reset data DR for condition truth are supplied to OR gate 1. Consequently, the internal memory holds the set state during the time from coming of condition truth signal DS to set the internal memory to coming of cindition truth signal DR to reset the internal memory. If switches SW 1  and SW 2  are opened and closed respectively, the internal memory circuit is set to the nonholding type. That is, since signal DR is broken and reset pulse RP is supplied to addressable latch part 3 in stead of signal DR, the internal memory circuit is set to the set state only during the time when signal DS for condition truth exists. Thus, the holding type and the nonholding type can be selected arbitrarily.

Title: Method for positioning image frame
Inventor: SETO YASUHIRO
IPC: G03B27/32
Filed: 1992-05-25
Abstract: PURPOSE:To accurately position an image frame even by the feed of a fixed quantity even though the faulty positioning of the image frame whose edge is not detected by an image frame detecting device occurs. CONSTITUTION:When transmission density distribution is abnormal, the edge of the frame is not detected. Then, in order to position the image frame by the feed of the fixed quantity, the mean value of the length of the image frame is calculated by adding the length L1n of the respective image frames whose number is (n) from the first image frame which is automatically detected and dividing it by the number of the frames (n), and the mean value of the space between the image frames is calculated by adding the space L2n between the image frames which is automatically detected and dividing it by the number of the frames (n-1). Since the carrying quantity for the feed of the fixed quantity is set based on the sum of the mean value of the size L1 of the normal image frames 16A(OK) before the image frame 16A which can not be detected in a carrying direction and the mean value of the size L2 of the space between the normal image frames even in the case that the image frame is not detected, the accurate positioning is executed by fitting a tendency peculiar to a processed negative film 16 in comparison with the previously set carrying quantity on standard.

IPC: G06F9/32
Filed: 1979-10-17
Abstract: PURPOSE: To reduce the count delay time and make various program branching possible, by constituting the program counter circuit with an adder circuit and a latch circuit.  
     CONSTITUTION: In case of instructions other than the jump instruction and the skip instruction, "L", "H" and "L" are given to signal input terminals 25, 23 and 24 respectively. In this case, the code signal which is obtained by adding 1 to the output of adder circuit 28 is obtained, and selecting circuit 29 selects the output of circuit 28 and supplies it to latch circuit 21. Consequently, when the clock pulse is supplied to terminal 22, the code signal of output signal terminal 27 is increased by +1. Next, in case of the skip instruction, circuit 28 transfers the code signal increased by 2 to circuit 29 because terminals 25, 23 and 24 become "H", "H" and "L"  respectively. Consequently, the output of circuit 28 is supplied to circuit 21, and the  code signal incerased by 2 is obtained at terminal 27. Next, in case of the jump  instruction, terminals 23 and 24 become "L" and "H" respectively, and circuit 29 selects the signal of signal input terminal 26 to supply it to circuit 21. Consequently,  the address code of the jump destination given to terminal 26 is obtained at terminal 27.

Title: Sense amplifier circuit
Inventor: MIYATA SHINOBU
IPC: G11C17/18
Filed: 1982-07-30
Abstract: PURPOSE:To shorten the time required for charging up the capacity of a digit line and to improve the operating speed, by inserting a P type transistor between power supply input terminals and connecting a gate to the output terminal of a sense amplifier circuit. CONSTITUTION:An electric current Ip which charges up the capacity of a digit line is I1+I2 and the capacity C1 is charged up by the electric currents I1 and I2. Since the potential variation of an output terminal C is sufficiently large in comparison with the potential variation of a gate voltage of QN2, and QP5 is biased sufficiently deep in comparison with QN6, the relation between the I1 and I2 becomes I2>M1 and the charging up current IP is sharply increased and, therefore, the charging-up time tp is sharply shortened. Moreover, if a memory cell QN4 is in an off-condition when the charging up of the capacity C1 is completed, the gate potential of the QN2 is lowered and QN1 is turned off and the output terminal C rises to the supply voltage and becomes an ''H'' level and QP3 is completely turned off.

Abstract: PURPOSE:To stabilize oscillation frequency, by selecting the laser oscillation frequency by means of an external resonator consisting of a light phase synchronizing loop, stabilizing the frequency by synchronizing it with the light injected from outside, and at the same time synchronizing it by using the frequency difference between injected light and oscillation light, when it is not in synchronism. CONSTITUTION:The oscillation frequency of semiconductor laser 1, which is temperature-controlled by oven 2, is selected by an external resonator consisting of the end surface of laser 1 and diffraction grating 5, and it is fine-tuned by means of tuner 4. By this, the frequencies are restricted within a certain width, and the light for laser 6 having a stable frequency is injected into laser 1 and it is made to synchronize with the oscillation frequency of laser 6. When the synchronism is disturbed due to oscillation power distortion, the light from laser 6 is separated by half-mirror 7, and by deviating the frequency by modulator 15, it is impressed on light receiver 18. On the other hand, the light from laser 1 is also separated by half-mirror 12 and is impressed on light receiver 18. It is negative-fed back to tuner 4 by using the beat signal produced during this time.
