IPC: H01B13/22
Filed: 1988-11-30
Abstract: PURPOSE:To obtain an insulating cable keeping copper color for a long period and having a satisfactory adhesion between an insulator and a hard copper stranded wire by applying a rust preventive solution to the hard copper stranded wire. CONSTITUTION:A rust preventive solution consisting of 0.1-10wt.% of benzotriazole or/and benzotriazole derivative, 0.2-10wt.% of a polyester plasticizer, and the remaining of a solvent is applied to the surface of a hard copper stranded wire, and then an insulating coating layer is formed on the outer circumference of the resulting hard copper stranded wire. Before coating of the insulator, the rust preventive solution having the polyester plasticizer addition amount reduced to 0-0.5wt.% is applied to the copper element wire made in contact with the insulator. Hence, an insulating cable having an excellent adhesion with the upper stranded copper element wire contacting with the insulator and excellent anti-corrosive film and protective film on the stranded conductor can be obtained.

Title: Substrate heater
Inventor: ASANO TAKAHIRO
IPC: B23K3/04
Filed: 1987-12-02
Abstract: PURPOSE: To prevent a heater from suffering from failure heating by heating a substrate while measuring actual temperature of a substrate conveyed in a substrate heating apparatus and controlling a heat amount of the heater. CONSTITUTION: When a conveyed substrate is detected with an arrival sensor 5 in a zone A indicated by a substrate heating apparatus 3, substrate conveyance with a conveyor 2 is interrupted for predetermined time, and a non-contact temperature sensor 6 within the region A indicated by the conveyor 2 is acted, and substrate temperature at that time is measured. When heating is insufficient for purposed temperature as a measured result of the substrate temperature, an increase of a heat amount of the heater 4 in the zone A is increased. At the time the purposed substrate temperature is attained, the increase of the heat amount of the heater 4 is interrupted, and thereafter the heater 4 heats the substrate keeping the heat amount unchanged. Further, when an overheated state is reached, heater output is interrupted or decreased.  The same operation is performed for later zones, i.e., from a zone B to a zone E.

Title: Liquid crystal display device
Inventor: OTA YUICHI
IPC: G09F9/00
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of air bubbles from a liquid crystal element and to decrease air bubble defects. SOLUTION: When the liquid crystal element 1 formed by using a polymer film as a substrate is subjected to slow pressing, then to sudden pressure releasing, the liquid crystals in a liquid crystal layer rapidly move at the moment of the pressure release and the liquid crystal layer attains a negative pressure state. Air bubble nuclei are then generated and while the dissolved air bubbles on the circumference are taken in, the air bubble nuclei grow in some cases. Even in the case of the instantaneous pressing, the negative pressure state is attained by the rapid movement of the liquid crystals and the air bubble nuclei are generated and grown in some cases. This device comprises a liquid crystal display part 1 using the polymer film as the substrate and a protective case holding a window frame disposed to face the display surface of the liquid crystal display part 1.  The end of the window frame facing the surface of the liquid crystal display part of the protective case are subjected to an angle treatment (angle parts are dropped as shown by 5b). The negative pressure air bubbles may, therefore, be prevented even in the absence of a bezel.

Abstract: PURPOSE:To perform a technical calculation at a high speed without using any expensive numerical arithmetic processor and at the same time to reduce the necessary capacity of a memory byperforming a numerical operation through an integer arithmetic and in a block floating point format. CONSTITUTION:A fixed floating point arithmetic using an integer arithmetic is expressed in a block floating point number that showed the data in an exponent part or a coefficient part common to all data and a fixed decimal point of each data. Then a block floating point arithmetic applying an integer arithmetic is carried out. It is supposed that a decimal, point is set at the 13th bit of an integer and then that 8192=2<13> of an integer is equivalent to 1.01 of a fixed decimal point. In this fixed decimal point format, the value covering -4.0 (minimum) through about 3.9999 (maximum) can be expressed. The expressible number most approximate to 0 is about 0.000122 and a number approximate to 1.0 has the decimal accuracy equivalent to about 4 digits. The diagram shows a program used for calculation of a complex number end applying a fixed decimal point in a C language.

Filed: 1990-11-09
Abstract: PURPOSE:To enable noise due to coupling capacity between adjacent digit lines to be restricted by placing the digit lines which are connected to first group and second group sense amplifiers alternately and then preventing the other group from being activated while one group is activated. CONSTITUTION:A digit line D and an anti D forming a pair of digit lines which are connected to a first group sense amplifier 1a and a second group sense amplifier 1b are placed alternately. Then, when a potential such as a word line WL1 is increased after pre-charge signals PDL1 and PDL for the first and second groups become H and the corresponding equalize transistor(TR) QE is turned on, the amplifier 1a is activated and a potential difference between the corresponding digit line D and the anti D becomes large. During this cycle, the amplifier 1b is not activated, the corresponding digit line D and the anti D are turned into precharged state, and signal on adjacent digit lines cannot be amplified simultaneously, thus enabling noise due to coupling capacity between lines to be restricted.

Title: Delivery valve
Inventor: FUJII TSUNESUKE
IPC: F02M59/46
Filed: 1988-12-02
Abstract: PURPOSE:To reduce a residual pressure in a fuel injection pipe to a proper value regardless of the magnitude of a fuel injection amount by a method wherein a relief valve is disposed to the valve seat of a communicating passage running through a valve body, and is energized through the force of a relief spring. CONSTITUTION:In the fuel delivery stroke of a fuel injection pump, not shown, a pressure on the downstream side of a delivery valve is increased, and since a valve body 1 is raised against the force of a valve spring 4 and is opened, fuel is delivered. Since, at the completion timing of fuel injection, a difference between the upper and lower pressures of the valve body 1 is reduced to zero, the valve body 1 is lowered through tension of the valve spring 4. Meanwhile, in a fuel suction stroke, a pressure on the downstream side of the valve body 1 is reduced, a relief valve 8 is opened to escape fuel on the upper stream side to the downstream side. When a difference between upper and lower pressures is decreased to a value lower than the set pressure of a relief spring 9, the relief valve 8 is closed and returned to its original position.
