Title: Magnetic recording method and magnetic recording and reproduction device
Inventor: ITOU KIYONARI
IPC: G11B20/14
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the change with time of recording magnetization by replacing a continuous nonreversing code train with a recording code train, which includes two continuous reversing codes having the reversing interval shorter than a code interval at the position that is out of a clock timing, and conducting a recording. SOLUTION: The magnetization formed on a vertical magnetic recording medium 2 having a positive direction is indicated by a white color and the magnetization having a negative direction is shown in a black color. If nonreversing codes, which do not generate reversing magnetization, are continuously produced in a first recording code train, that is correspondingly generated with a recording current, while a magnetic head is relatively moved from the left to the right, the code train, that includes the continuously reversing codes in which magnetization is reversed with the interval shorter than the case of continuously reversing codes in the first recording code train, is replaced with a portion of the nonreversing codes or all of the codes and a recording is conducted.  A second recording code train is generated like this, the recording current corresponding to the second recording code train is supplied to the magnetic head for a recording to form a desired recording magnetization condition.

Title: Control circuit for motor-driven driver
Inventor: TOKURA HIROAKI
IPC: H02P1/16
Filed: 1983-01-31
Abstract: PURPOSE:To prevent the damage of a screw and a screw hole by providing a slow starting function for lowering the electric power for a motor supplied at the initial starting time. CONSTITUTION:When an initial start signal is applied to a driver 13, a transistor T3 is turned ON, and a counter 4 produces an output Q. A timer 5 is operated by this output, and produces an output <->Q for the prescribed period. This output is inverted by a Schmitt trigger 20, inputted to the base of a transistor T2, thereby energizing a relay 7, and an electric power for a motor is supplied through a load resistor R12 to the driver 13. When the prescribed time is elapsed, the relay 7 is deenergized, the power for the motor is supplied directly to the driver 13. When twice start signals are applied in one cycle operation, the output of the counter 4 becomes inverted state. Accordingly, the timer 5 does not set the time, and the power for the motor is supplied directly to the driver 13.

Title: Device for checking upper limit value of reactor physical test of zero-power of nuclear reactor
Inventor: HORIMOTO TOSHIAKI
IPC: G21C17/108
Filed: 1989-01-24
Abstract: PURPOSE:To easily and surely check the upper limit value of the reactor physical test of a zero-power by detecting the current obtd. from a neutron detector, inputting the detected current value and time and calculating a regression line by a regression calculation. CONSTITUTION:A current detector 2 detects the current signal obtd. from the neutron detector 15 for detecting neutron fluxes and supplies the signal to an arithmetic unit 4 after A/D conversion 12. The neutron flux increases exponential-functionally when the positive reactivity is applied from the critical state to the reactor. This neutron flux is measured at equal intervals, is plotted to a plotter of an X-Y recorder, and is stored in an external memory device 6. The regression calculation is simultaneously made by the unit 4 to calculate the straight line 13a. Judgment is made that the inclination by a Doppler effect arises when the plot point of the neutron flux level deviated by a certain width from the straight line 13a is obtd. Further, the neutron flux level is sampled at several points and the regression calculation is made (the calculation is made at the sampling point after the generation of the inclination) to calculate the straight line 13b. The intersected point of the straight lines 13a and 13b is measured as the upper limit of the reactor physical test of the zero-power.

Filed: 1990-01-25
Abstract: PURPOSE:To effectively exclude a defective product without executing a useless bonding operation by a method wherein, when any one out of an IC chip, a lead frame and a terminal is dislocated, it is detected. CONSTITUTION:An image signal which has been picked up by using a video camera 12 is displayed on a monitor screen 13; it is sent to a computation part 14 and computed. A check part 15 compares data obtained from a plurality of images, and checks whether a lead or a pad has been recognized erroneously or not. A control part 16 moves an X-Y table 19 and generates a control signal used to align a bonding position. A bonding head 18 is actuated by a drive part 17. At this stage, straight lines X1, X2, Y1, Y2 formed by rows of leads 5 are found; distances between four apexes of an IC chip which have been found separately and straight lines are computed and designated as l1, l2, l3, l4. When the chip is dislocated in parallel and a dislocation amount is large, l2 becomes excessively large and l4 becomes excessively small. Thereby, whether the dislocation amount of the IC chip is within a permissible range or not can be judged.
