Title: Conductivity improving method for copper powder
Inventor: MIYAGAWA NAOFUMI
IPC: H01B1/00
Filed: 1994-11-22
Abstract: PURPOSE: To suppress surface oxidizing of copper powder and positively improve conductivity even during preservation and transportation by storing the copper powder in a packing film with an absorbent of absorbing oxygen and water, and sealing the packaging film in a vacuum. CONSTITUTION: Copper powder and an absorbent, stored in a permeable bag to absorb oxygen and water, are stored in a packaging film of high air-tightness. This packaging film is placed in a vacuum packaging machine and sealed. From the beginning, oxygen and water in the packaging film are sufficiently removed, to maintain its absorbing force for a long period, to continue absorbing oxygen and water in the packaging film. In a copper powder surface of large surface acitivity, its surface sticking oxygen and water are absorbed. As the result, by advancing deoxidizing and dewarering the copper powder, its conductivity is improved from the initial value. The absorbent in use is a mixture of an active organic substance and an inorganic substance.

Title: Optimization system for production system
Inventor: ISHIDA TORU
IPC: G06F17/30
Filed: 1987-12-10
Abstract: PURPOSE:To minimize the join arithmetic value by optimizing the method (join topology) for sequence and combination of the join arithmetic operations at the condition part of each rule of a production system based on the dynamic characteristics of a program. CONSTITUTION:An initial topology is produced with input of an unoptimized production rule and a set of nodes is obtained. Then two nodes are selected out of said set of nodes for production of a test node which performs the joint arithmetic operation. The cost of the test node is evaluated. Then the test node is eliminated if it is not necessary and then added to the set of nodes if necessary. Then the termination node having the lowest cost is selected out of the set of nodes and an optimized production rule is produced based on the selected node. The cost of the test node is evaluated by applying the equivalent conversion to the sequence and combination of the join arithmetic operations for decision of conditions based on the measurement data on the dynamic characteristics of a production.

Inventor: TSUKIJI MASARU
IPC: H01L21/336
Filed: 1993-12-14
Abstract: PURPOSE:To reduce electrical stresses applied to a tunnel insulation film and to suppress the fluctuation in threshold value accompanied with the repetitions of write/erase when pulling out electric charge accumulated at the floating gate to a semiconductor substrate in a floating gate type non-volatile memory. CONSTITUTION:N-type source 6 and drain T are formed on a P-type semiconductor substrate 1, and a first insulation film 2, a floating gate 3, a second insulation film 4 and a control gate 5 are formed by lamination on a channel region between the source and drain. When negative voltage pulses are applied to the control gate 5 for pulling out an electric charge accumulated at the floating gate 3 to the substrate, then a depletion layer is extended within the floating gate 3 and a voltage applied is mostly given to the depletion layer, by which the electrical stresses applied to a tunnel insulation film can be suppressed. The pulling out of the electric charge is performed efficiently through an electric charge created by avalanche amplification within the depletion layer.

Inventor: SHIBATA KAZUNARI
IPC: H01J29/87
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To securely ground a safety glass surface of a front surface of a cathode-ray tube so as to prevent the charge, and to securely prevent the explosion of the cathode-ray tube, and to facilitate the removal of a metal band at the time of recycle by sewing conductive fibers in an adhesive tape. SOLUTION: Conductive fibers 3 are sewed in a supporting base 1 so as to form a conductive adhesive agent 2, and while an exposed conductive fiber part 31 of the supporting base 1 is made to contact with a metal band 7, and an exposed conductive fiber part 32 of a surface of an adhesive agent 2 is made to contact with a surface of a sealing conductive tape 61. Since the conductive fiber 3 can be safely held without generating a damage thereof in relation to the shrinkage of the metal band 7, the sealing conductive tape 6 and the metal band 7 can be securely electrified with each other. Since a conductive film 52 of a most front surface of a cathode-ray tube 4 is set at a grounding electric potential by grounding the metal band 7, charge can be prevented.  With this structure, strong connection of the metal band 7 and a panel part 41 to each other is avoided so that the metal band 7 can be easily removed at the time of recycle.

Title: Display controller
Inventor: ISHIYAMA YUKIO
IPC: G09G5/22
Filed: 1990-11-19
Abstract: PURPOSE:To attain high-speed access and to save electric power by rapidly receiving the access from a main device and activating a character memory pattern only during this access period at the time of making urgent access from a main device. CONSTITUTION:The output of flip-flop F1 rises to a HIGH level when the instruction for a low-current consumption mode is written into the flip-flop F1 from the main device. The output of the flip-flop F2 rises to the HIGH level at the fall of the next signal TMGS tuned to the display access of the character pattern memory and, therefore, the same state as the state of forcibly raising the signal HACH to the HIGH level is obtd. in an OR gate G1 and the output of an AND gate G2 falls to the LOW level only when the output of a selector S1, i.e., the signal HST, falls to the LOW level and, therefore, the control signal of the character pattern memory which is the output of an OR gate G3 attains the LOW level active only when the request for the memory access form the main device is detected. The signal attains the HIGH level (inert) in the periods exclusive of the above-mentioned period. The unnecessary currents are thus controlled.
