Title: Redundancy system for semiconductor device
Inventor: ADACHI YUKINOBU
IPC: G11C29/04
Filed: 1988-07-12
Abstract: PURPOSE:To make the distance between a fault bit and normal bit larger by relieving the adjacent bit line pairs of the bit line pair in which the faulty bit occurs. CONSTITUTION:When a faulty point A occurs in a bit line pair B and the inverse of B connected with a sense amplifier, the adjacent bit line pairs B and the inverse of B on both sides of the faulty bit line pairs B and the inverse of B in which the faulty point A occurs are relived together with the faulty bit line pairs B and the inverse of B. Therefore, the distances between the faulty bit line B and the inverse of B and normal bit line pairs B and the inverse of B become larger and adverse influences from the faulty bit line pair B and the inverse of B to the normal bit line pairs B and the inverse of B can be reduced.

Title: Shape detecting method
Inventor: NAKAO SHINYA
IPC: G01B11/00
Filed: 1993-07-14
Abstract: PURPOSE:To accurately detect a shape when portions having a sharp density change other than a detected object exist by converting the partial density correlation value with a conversion table constituted of optional functions having output values below input values. CONSTITUTION:A circle 22 having the same shape as that of a circular hole to be detected is assumed, and eight small regions Ra-Rh (density reference regions) made of picture elements are set on and near the periphery of the circle 22 respectively. The relative positions of the picture elements constituting these regions with an attention picture element O are stored in a memory, and coefficients are set. A product of the set coefficient and the detected image density is obtained, and the sum of the products is obtained for each small region as the partial density correlation value. The partial density correlation value is converted by a conversion table constituted of optional functions having output values below input values, and the total sum of them is obtained. This process is repeated while the attention picture element O is moved, and the position of the attention picture element O where the total sum of the partial density correlation values becomes the maximum is judged as the existing position of the circular hole (detected shape).

Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To improve the attracting performance of a means for transporting a material to be transferred by applying an electric charge on the electric field dependency type resistance layer of this means for transporting the material to be transferred, thereby attracting the material to be transferred. SOLUTION: The charge is applied on the electric field dependency type resistance layer 80 by attraction Corotron in the attraction start position where the attraction starts at the time of electrostatically attracting a paper by a transfer film 42. The charge of the polarity reverse to the polarity of the charge of the electric field dependency type resistance layer 80 is induced in the roll for attracting the material to be transferred and an electric field is generated in the circumference of the electric field dependency type resistance layer 80, thereby, the resistance value of the electric field dependency type resistance layer 80 is lowered.  As the result, the charge applied on the electric field dependency type resistance layer 80 moves to a photoreceptor layer 70 side and the paper 12 is electrostatically attracted on this photoreceptor layer 70 in the attraction start position. There is no electric field in the circumference of the electric field dependency type resistance layer 80 on the downstream side form the attrition start position in the direction where the material to be transferred is transported. The resistance value of the electric field dependency type resistance layer 80 is thus increased and the movement of the electric charge is restricted.

Inventor: SUGAYAMA SHIGERU
IPC: H01L29/74
Filed: 1984-08-24
Abstract: PURPOSE:To realize the stable operation, by connecting in parallel two gate turn-off thyristors in each of which two gate terminals are connected to a package separately from a gate electrode. CONSTITUTION:Anode terminals 9A and 9B are connected to each other with an external lead 101, and main current flows between a cooling fin and the lead 101. Gate terminals 10aA and 10aB are connected to each other with an external lead 102, while gate terminals 10bA and 10bB are connected to each other with an external lead 103. When the gate is turned OFF and a gate signal is applied to the leads 101 and 102, a potential difference is produced between gate electrodes 8A and 8B. Since the lead 103 is disposed between the gate terminals 10bA and 10bB, electric current flows therethrough to nullify the potential difference between the electrodes 8A and 8B. The unbalance in the main current between the gate turn-off thyristors is alleviated in this manner.

IPC: H01H33/91
Filed: 1989-07-06
Abstract: PURPOSE:To enhance the arc extinguishing performance by extending the tip of an insulated flow guide till the position covering the foremost surface of a movable arcing contact, and confronting the inside surface of the tip of flow guide to the outside surface of a fixed arcing contact. CONSTITUTION:When a gas blast circuit breaker as per the present invention is to be shut, the arc 19 contacts not only the throat part 13a of an insulated nozzle 13 but the throat part 20a of an insulated flow guide 20. Accordingly gas is generated also from this throat 20a, and it flows into a buffer chamber 9 from a discharge path 12. This boosts the pressure in the buffer chamber 9 above a conventional arrangement. Thus the insulative gas in the buffer chamber 9 with boosted pressure is compressed by a piston 17 and blasted to the arc from the discharge path 12. Because of provision of the insulated flow gas 20, the opening of the discharge path 12 separates from a movable arcing contact 7, so that the cooling ability for the arc in the neighborhood of an insert hole 11 is enhanced, which enhances the arc extinguishing performance.
