IPC: G11C11/41
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain a memory device which can be accessed at high speed by preventing that a precharging operation and the time required for a read operation from, and a write operation to, a memory cell become an obstacle to a high-speed operation. SOLUTION: An address selection circuit 7 which connects a bit line 2 and a bit line 11 as two systems to a plurality of memory cells 1 used to store data and which controls an access operation to the respective bit lines 2, 11 is provided. An input/output selection circuit 8 in which the input/output operation of the respective bit lines 2, 11 is performed and in which the bit lines 2, 11 are selected is provided. The bit lines 2, 11 as the two systems perform a precharging operation to two machine cycles once each so as to be deviated by one machine cycle, and they perform a read operation from, and a write operation to, the memory cells 1. Thereby, the time required for the read operation and the write operation in the respective bit lines 2, 11 can be ensured to be twice as compared with that in conventional cases.  As a result, when the cycle of a fundamental clock 11 is reduced to 1/2, the high speed of a memory access operation is realized.

Title: Surface treatment of tile joint
Inventor: FURUYA KENGO
IPC: E04F13/08
Filed: 1989-03-20
Abstract: PURPOSE:To relieve repairing work as well as prevent cracking of tile joints by a method in which the surface of tile joint is flame-coated with a metal to form a metal film. CONSTITUTION:The flame coating of aluminum is applied by a low-temperature arc coating method to the surface of a tile joint 13 between the adjacent tiles 12 of a tile face 11 to form a metal film 14. In this case, the metal so coated adheres to the surface of the tiles 12, but is simply wiped out of the smooth surface of the tiles 12, where the metal coating is fixed to the surface of the tile joint 13 and the surface of the tiles 12 are kept original. The repairing work can thus be greatly relieved because no cracking or delamination occurs even under high-temperature and high-humid conditions for long periods.

Title: Wheel readhesion control method in gliding detector
Inventor: NAGASE KAZUHIKO
IPC: B60T8/1761
Filed: 1978-06-07
Abstract: PURPOSE: To reduce damping distance and damping time in the control system which prevents regliding after readhesion of the wheel.  
     CONSTITUTION: When braked in damping, the speed decreases gradually as shown in the diagram, but if a damping force greater than adhesion between the wheel and the rail is applied to, a gliding is occurred, the wheel speed decreases rapidly as in the time interval from t 1  to t 2 . At this time, the occurrence of gliding is detected according to the difference between the speed of braked wheel and the highest speed of all wheels or the speed decrease rate of wheel, an air send-out command and an air feed-off command for the brake are delivered to release the braking pressure by the detecting signal. When the gliding is extinguished and the wheel speed is raised by this way, the braking pressure is enhanced again since the wheel is readhered to the rail at t 3 . In this case, first the braking pressure is recovered up the 80% of the value before gliding for example, and the remaining 20% is done after sure readhesion.

Filed: 1985-04-01
Abstract: PURPOSE:To make it possible to take out a higher current than before by applying an alkaline earth metal oxide containing zirconium carbide as the first layer to a substrate metal mainly composed of nickel while applying thereto the alkaline earth metal oxide containing one or plural kinds of nickel powder or the like as the second layer. CONSTITUTION:In a cathode formed by coating a substrate metal mainly composed of nickel with an electron discharge material layer consisting of an alkaline earth metal oxide containing barium, the alkaline earth metal oxide containing 0.1-2wt% of zirconium carbide is applied in adjacent to the substrate metal as the first layer. Then thereto, the alkaline earth metal oxide containing 0.1-2wt% of one or plural kinds of alloy powder consisting of nickel powder, or cobalt powder or nickel and cobalt are applied. When the amount of zirconium carbide to be added to the alkaline earth metal oxide is smaller than 0.1%, the reduction of the alkaline earth metal oxide is not sufficient while improving no electron discharge. When exceeding 2%, the reduction leads too far thus generating surplus Ba and being evaporated and shortening life.

Title: Optical axis aligning device for vehicle headlamp
Inventor: TAKEDA HITOSHI
IPC: B60Q1/115
Filed: 1983-04-20
Abstract: PURPOSE:To prevent any hunting from being produced while preventing a current from keeping on flowing through a relay of a motor control circuit by providing two voltage comparators for detecting the sign of a difference between voltages outputted respectively from an optical axis set part and an optical detecting part. CONSTITUTION:When optical axis detection voltage Vd by a variable resistance VR2 is higher than voltage Va set by a variable resistance VR1, output voltage from a voltage comparator COM1 is H while that from a COM2L, and thereby only a relay RL1 is energized through a transistor Q1, allowing driving motors ML, MR to be inversely turned to cause an optical axis to be inclined downward. When Vd<Va is attained, the output from the COM1 changes to L to cause the driving motor to be stopped, but the voltage Vd becomes lower than Va due to inertia. Against this, the output from the COM2 never become H resulting in no huting if a difference between the lowest limit set voltage Vb and the upper limit Va of the optical axis is properly set by resistance R11. Further, no current keeps on flowing through the relay, avoiding the temperature rising thereof.
