Inventor: NAGAKURA YOSHIYUKI
IPC: G01B17/00
Filed: 1992-06-22
Abstract: PURPOSE:To enable a self-traveling flaw detecting device to perform highly accurate flaw detection when the device is actuated after the device is carried onto a plate to be inspected and moved to a starting position by providing ultrasonic transmitters-receivers which transmit and receive surface waves for measuring the distances to the edges of the plate to be measured. CONSTITUTION:Ultrasonic transmitters-receivers 16A and 16A' which are mounted on the front face of a self-traveling truck 12 and transmit and receive surface waves in the advancing direction of the truck 12 perform position measurement in the advancing direction and meandering control when the truck 12 advances in the direction shown by the arrow A. In addition, ultrasonic transmitters-receivers 14A and 14A' which are mounted on one side face of the truck 12 and transmit and receive surface waves in the direction perpendicular to the advancing direction of the truck 12 perform position measurement and meandering control in the direction perpendicular to the advancing direction of the truck 12 from the distance to the edge 10A of a plate 10 to be inspected. Since the meandering of the truck 12 is prevented by the actions of the transmitters-receivers 14a and 14A' and 16A and 16A' mounted on the truck 12 in the advancing direction and the direction perpendicular to the advancing direction two sets by two sets, the plate 10 can be inspected for flaw with high accuracy by means of a flaw detecting sensor 18A mounted on the front section of the truck 12.

IPC: G11C16/02
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To elongate the life of a memory cell for erasing data, by providing a control circuit for changing an erasing voltage, which is applied on a control gate CG based on identification data. SOLUTION: A control core circuit counts the number of data rewritings. At every time when the counted value exceeds the specified value and the like, the fact is stored in a memory cell 101. Thereafter, when the number of the data rewritings exceeds the specified value, a row decoder increases the voltage applied on the selected word line by 1 V from the initial value in the erasing mode and sets the voltage an 13 V. By the same way, the erasing voltage is increased by every 1 V at every time when the number of the rewritings exceeds the specified value. Thus, the advance of the abrasion and deterioration of a silicon oxide film 104 as a tunnel oxide film formed between a floating game FG and a control gate CG can be controlled, and the operating life of the memory cell 101 can be elongated.

Filed: 1986-07-11
Abstract: PURPOSE:To attain the good quality special reproduction without using a head for special reproduction by having a pair of heads and an image memory circuit to synchronize to a head changingover pulse and operate it. CONSTITUTION:A changing-over switch 15 is changed over by a pulse from a gate pulse generating circuit 17, and also for an image memory circuit, the writing and reading of a reproducing image are controlled by the same pulse. A head changing-over pulse generating circuit 18 is connected to the circuit 17, and when the reproduction by one side magnetic head 2a is executed, a gate pulse instructing the memory to the memory 14 is outputted from the circuit 17. Consequently, at the time of the frame feeding reproducing mode, the reproduction output by one side head 2a is written to the memory circuit 14 by the above-mentioned gate pulse, while a head 2b is traced, the switch 15 is changed over to the memory 14 side by the above-mentioned gate pulse and the latest reproducing image of the memory 14 is read. In consequence, the same reproducing output by the head 2a is continuously outputted in a pair, and the excess of the noise bar due to the difference in the azimuth of both heads at the time of the frame feeding reproduction is eliminated.

Title: Power supply circuit
Inventor: SUGAWARA SHOGO
IPC: H02J1/00
Filed: 1991-06-10
Abstract: PURPOSE:To ensure dielectric strength through a simple constitution wherein a current transformer is fed with primary current from an AC current supply circuit and a current/voltage converter is connected to the secondary of the current transformer. CONSTITUTION:Primary currents of current transformers(CTs) 5a, 5b are fed from an AC power supply circuit 4. Current/voltage converting circuits 6a, 6b for converting the secondary current into power supply voltage are connected to the secondary of the CTs in order to feed driving circuits 3a, 3b with regulated voltages. Since an insulating means comprises the CT, only several turns are required on the primary and thereby the inter-winding capacitance can be decreased remarkably. Consequently, resonance between isolated power supplies due to inter-winding parasitic capacitance or imbalanced voltage at the time of series connection of semiconductors can be eliminated.
