Title: Manufacture of image display
Inventor: SUZUKI ATSUSHI
IPC: H01J9/24
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To enhance manufacturing efficiency, reduce the thickness of an adhesive resin layer and suppress peeling-off by allowing one side of a front panel to abut against one side having a greater thickness of the adhesive resin layer which is applied to a flat panel in such a manner that one side becomes thicker with inclination of the flat panel in the state in which the front panel is inclined with respect to the flat panel, followed by overlapping with each other, and by hardening the resin layer. SOLUTION: A reinforcing band 10 slightly projecting from a flat panel face 22 can prevent an adhesive resin 13 from flowing out and facilitate positioning of a front panel 8. The adhesive resin 13 having a predetermined viscosity is applied, with movement of nozzles, to the inclined flat panel face 22 of a bulb 11 placed on support mounts 52a, 52b which are different in height from a horizontal level 50. The thickness of the adhesive resin 13 is different on both short sides. After being left for a short time, the front panel 8 inclined at an angle α of 10-20 deg. with respect to the flat panel face 22 abuts on one side 8e thereof against the other side having a greater thickness of the adhesive resin 13, and then, gradually falls by pressing, so that the adhesive resin 13 is hardened by an ultraviolet ray. With this constitution, bubbles is difficult to be generated.

Title: Electrodeposition coating method
Inventor: OTAKE MAKOTO
IPC: C25D13/10
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To decrease the amt. of the tar and soot in a baking furnace by drying and removing the moisture sticking to a electrodeposition coating film at a prescribed temp. before curing this coating film in the furnace. SOLUTION: This coating method comprises subjecting a material to be coated with a coating material contg. a cationic resin and a block isocyanate compd. to electrodeposition coating and drying and removing all of the moisture sticking to and impregnating in the coating film at 40 to 70 deg.C, after washing with water, then curing the coating film by heating in the baking furnace. The removal of the moisture among the stages described above is to be noted particularly. An important care is not to allow the steam, etc., of the removed moisture to flow into the furnace. Namely, this drying stage is required to be executed as a stage separate from the subsequent baking stage. Consequently, the amt. of the tar and soot generated in the furnace is drastically decreased.  If the drying temp. exceeds 70 deg.C, dirt and dust stick to the coating film lead to the degraded appearance of the coating finish and, therefore, such temp. is undesirable.

IPC: G11C11/409
Filed: 1989-01-27
Abstract: PURPOSE:To improve the data readout speed by connecting a 1st wiring element located at a sense amplifier circuit block side and a 2nd wiring element located opposite to the sense amplifier circuit block side at both ends of the wiring only. CONSTITUTION:A slit SLIT extended in the prolonged direction is formed in a wiring SAN and the 1st wiring element SAN 1 located at the side of a sense amplifier circuit block 10 with respect to the slit SLIT and the 2nd wiring element SAN 2 located opposite to the sense amplifier circuit block 10 are connected only at both ends of the wiring and plural sense amplifier circuits 10 are connected in common to the wiring element SAN 1. Thus, the current source 2 and the sense amplifier circuit SAMn parted most from the current source 2 are connected by the 2nd wiring element SAN 2 and the voltage drop due to the parasitic resistance of the wiring is reduced. Thus, each sense operating speed of the sense amplifier circuit close to the current source and the sense amplifier circuit apart from the current source is made nearly equal to each other, thereby improving the data readout speed.

Title: Blower protection method
Inventor: SHIBATA MINORU
IPC: F23J15/00
Filed: 1993-02-05
Abstract: PURPOSE:To inexpensively resolve the problem of surging of blower at starting by continuously supplying coolant gas when the exhaust gas temperature of an incinerator at starting is lower than a temperature set lower than a heat- resisting temperature of filter. CONSTITUTION:The temperature of exhaust gas having passed a cooler 4 is measured with a thermometer at starting and whether this is below the set temperature is judged. The set temperature is set lower than the heat-resisting temperature of a secondary filter 5. As the result of the judgment while the measured exhaust gas temperature is lower than the set temperature, it is judged the starting state of an incinerator is continued and a valve 12 is opened fully for example, to supply a determined amount of air. When the measured exhaust gas temperature exceeds the set temperature for the first time, the completion of starting is judged and by switching to the normal feedback control, the valve 12 is controlled so that the exhaust gas temperature measured with the thermometer 11 becomes the set temperature. When the incinerator becomes the state of operation completion, the feedback control is terminated.

Title: Current limiter for synchronous generator
Inventor: KITANI YOSHIAKI
IPC: H02P9/14
Filed: 1987-01-28
Abstract: PURPOSE:To prevent a burning defect, etc., from occurring by inputting the sum of the multiplication output of a reactive power converter output and an overcurrent detector output, and a reactive power converter output to an automatic power factor regulator. CONSTITUTION:When the output current of a synchronous generator is the set value or lower of an overcurrent setter 20, the output (y) of the detector 20 is zero. Accordingly, the input signal of an automatic power factor regulator 12 becomes only (p) from a power factor setter 11 and (x) from a reactive power converter 16 to obtain a constant power factor operation. Then, if the output current of the generator exceeds the set value of the setter 20, the setter 20 outputs an output (y), and a multiplier 22 outputs an output z = xy. Then, an automatic power factor regulator 12 increases or decreases a set voltage V0 so that z + x = x (y + 1) of the addition of the output (z) and the output (x) of a reactive power converter 16 is equilibrated with the output (p) of the setter 11. Thus, the overcurrent can be suppressed to the minimum limit.

Filed: 1981-02-13
Abstract: PURPOSE:To stop constant voltage power supply output at a reset signal output, by making the reference voltage for a constant voltage power supply circuit and a reset circuit common so that the operation limit voltage of a control logical circuit and a reset detection voltage can be equal. CONSTITUTION:A Zener diode 19 is set as a reference voltage element, and a current flows with fixed resistors 17, 18. A transistor (TR) 15 detects a current flowing to the Zener diode 19 and collector current is outputted. For example, if a power supply voltage Vcc is decreased and approaches the reference voltage, the current decreases extermely and the TR15 turns off. A fixed resistor 16 is ready to obtain logical outputs ''0'', ''1'' and the logic ''0'' is obtained at the on- state of TR15 and a reset signal is generated via a diode 13. Thus, the function of a control logical circuit 24 is stopped. At reset, a voltage of the resistor 16 is at ''0'', the base voltage of a TR20 approaches ''0'' via a diode 23 to turn off the TR20 and to stop the output of constant voltage power supply.
