Title: Protecting device for gate turn-off thyristor
Inventor: YANAGIDA KEIICHIROU
IPC: H03K17/73
Filed: 1981-03-31
Abstract: PURPOSE:To prevent the delay in the protecting operation of a gate turn-OFF thyristor (GTO) by providing an AND circuit for inhibiting an OFF gate signal to the GTO. CONSTITUTION:When GTO thyristors 6a, 6b are simultaneously fired, a shortcircuit current flows from a power source 1, and a current simultaneously flows through current detectors 10a, 10b, thereby facilitating the simultaneous firing of the thyristors 6a, 6b of respective upper and lower arms 12a, 12b. Since the arms 12a, 12b are not absolutely simultaneously fired at the normal control time, the protection can be effectively performed. Accordingly, when its state is detected to inhibit the OFF gate signals of the GTO thyristors 6a, 6b, the thyristors can be protected without time delay.

The plating soln. here is fluidized so as to satisfy  the relation between the traveling speed U of the steel strip and the jetting speed U1 of the plating soln. when the required value of the relative flow rates between the electrode surfaces  and the plating soln. is defined as UA, and the required value of the relative flow rates between the surfaces of the steel strip and the flow of the plating soln. as Ux. More specifically,  the electrode side is set at the equationIand the steel strip side at the equation II in the case of counter current, and the electrode side is set at the equation III and the steel strip side at  the equation IV in the case of forward current. The automatic control of jetting is made possible if a detector 13 for the speed U and a pump 14 for controlling the discharge from the  nozzles 8, 9 are provided to the device through an electronic circuit 15 for braking.

Title: Method for controlling amount of exposure
Inventor: OZAWA KEN
IPC: H01L21/027
Filed: 1993-03-08
Abstract: PURPOSE:To eliminate the need for creating a complex control map for each exposure device by improving throughput by reducing time required for energy adjustment process before correction exposure. CONSTITUTION:The amount of proper exposure for a wafer is divided by an average pulse energy to obtain the number of average rough exposure pulses N. The actual amount of integration exposure to the wafer is divided by the proper amount of exposure under conditions where the number of average rough exposure pulses N is equal to or more than the number of minimum pulses Nmin to obtain a target accuracy R and then rough exposure is performed until the target accuracy R reaches a rough exposure end criterion level Rc. After that, the rate for reducing light for pulse light is set to a specific state and then exposure is performed by the cutoff control system until the target accuracy R reaches the correction exposure end criterion level Rcc.

Title: Controlling method for thickness of tail end of strip
Inventor: HAMAMOTO YASUO
IPC: B21B37/72
Filed: 1980-04-09
Abstract: PURPOSE: To previously decrease the interstand tension for diminishing the influence of disappearance of tension of the next stand, to be caused by the dropout of tail end of the strip, and to reduce the amount of off-gauge strip, by increasing the roll gap of the next stand just before the tail end of strip drops out of the preceding stand.  
     CONSTITUTION: When the tail end of strip S passes over the detector 4, the timer 11 generates and inputs a signal to the screw position controller 12 after a prescribed time. The screw position controller 12 thereupon computes the correction value for the roll gap of the stand 2, and sends out a signal to the screw down device 9 which then increases the roll gap of the stand 2 so as to decrease the strip tension between the stands 1, 2 to ≤50% of the strip tension working just before increasing the roll gap. Thereby, the fluctuation of strip thickness in the stand 2, to be caused by disappearance of tension as a result of dropout of the tail end of strip S from the stand 1, is decreased. When the tail end of strip S passes over the load cell 5, the screw down device 10 increases the roll gap through the timer 11 and the screw position controller 12 similarly to above; hereby, the strip tension between the stands 2, 3 is decreased and the correcting operation is repeated so as to decrease the fluctuation of thickness in the stand 3.

Title: Reverse insertion detecting system for betting ticket in betting ticket pay-back device
Inventor: ARIMA HIROHIKO
IPC: G06Q50/10
Filed: 1990-02-27
Abstract: PURPOSE:To smoothly execute pay-back work by reading image data (bet contents) recorded onto a betting ticket by an optical reading means and detecting it when which character (figure) this signal is can not be recognized whether the betting ticket is inserted to a betting ticket pay-back device in a normal state or not. CONSTITUTION:When the signal read by the optical reading means can not be recognized as image data 2, the state of inserting a betting ticket 1 to the betting ticket pay-back device is investigated at first by calculating the position of auxiliary data 3, which is recorded onto the betting ticket 1, to the optical reading means. As a result, when it is discriminated that the betting ticket 1 is inserted in the reverse state, the betting ticket 1 is returned to a betting person and it is guided by a sound, etc., to insert the betting ticket 1 again in the regular state. When it is not decided that the betting ticket 1 is inserted in the reverse state, it is judged that the image data 2 recorded onto the betting ticket 1 is defectively read. Thus, the case of the original read defect is distinguished from the case of the read defect caused by the reverse insertion and the pay-back work is smoothly executed.

Title: Culture of bacteria
Inventor: YAMADA HIDEAKI
IPC: C12N1/20
Filed: 1989-02-28
Abstract: PURPOSE:To obtain cell bodies of Rhodococcus rhodochrous which produces nitrile-hydratase in high yield by adding at least one selected from specific urea derivatives and cobalt ion to the culture medium. CONSTITUTION:At least one selected from urea derivatives of formulas I through IV such as methyl urea of urethane (the concentration is 1 to 30g/lifter) and Co ion such as cobalt chloride (the concentration is 5 to 15mg/lifter calculated as CoCl2) are added to the basic culture medium containing glucose or the like. Then, the cell bodies of Rhodococcus.rhodochrous J.1 strain (FERM No.1478) is cultured in the medium at 15 to 50 deg.C over 30 hours. This cultivation very markedly increases the nitrile hydratase activity per unit volume of the culture mixture. This phenomenon is presumable due to the increase in cell body concentration (cell body yield) and/or the activity of cell bodies (the amount of the enzyme, nitrile hydratase in cell bodies) and the present invention is very effective for increasing the hydratase concentration.

IPC: H04N5/782
Filed: 1984-03-12
Abstract: PURPOSE:To eliminate noise on a reproduction picture plane by using two rotary magnetic heads which have the same head gap tilt and reproducing one recording track repeatedly during still picture reproduction. CONSTITUTION:When a start signal (a) for still picture reproduction is applied, a circuit 6 is turned off and a circuit 11 is turned on. A motor low-speed driving signal is therefore applied as a signal (c) to a circuit 7 and a magnetic tape is switched to a low-speed run. A circuit 21 is off during normal reproduction and turned on by the application of the signal (a); and its output is inputted to a level discrimination circuit 19 and a signal (s) is outputted when the voltage level of an output (j) rises above a specific level, integrated by a circuit 20, and inputted to a circuit 12 as a signal (t). When the output (t) is above the specific level, the circuit 13 is turned off with an output (k) and a capstan motor 8 stops. When the magnetic tape is run at a low speed in a reproduction state and scanning track of magnetic heads A1 and A2 shift regularly in order. Therefore, an optimum still picture is obtained by stopping the tape run when the playback signal level does not drop.
