Title: Dielectric barrier discharge lamp device
Inventor: HISHINUMA NOBUYOSHI
IPC: G21K5/00
Filed: 1994-11-25
Abstract: PURPOSE: To sufficiently improve the irradiation just under discharge lamps, so as to make high efficiency and high reliability by preventing the illuminance distribution from being made uneven with the elapsed lighting time, by providing approximately V-shaped light reflecting plates between mutually adjacent discharge lamps. CONSTITUTION: V-shaped light reflecting plates 11, 13 constituted by bending an aluminum plates are provided between cylindrical dielectric barrier discharge lamps 1a, 1b and between 1b and 1c. The vertexes 12, 14 of these plates 11, 13 are positioned on a common tangent PQR on the peripheries of the lamps 1a, 1b, 1c facing a light take-out window 20. The space 26 between the lamps 1a, 1b, 1c and the window 20 is filled with gaseous nitrogen injected from an inert gas introducing port 24. Since the vacuum ultraviolet ray is not absorbed by the space 26, the total vacuum ultraviolet ray discharged from respective lamps is discharged from the window 20, and the window 20 substantially forms a rectangular vacuum ultraviolet ray beam. Accordingly, the light taking-out efficiency is improved, and the uniform irradiated surface can be obtained.

Title: Suspension device for vehicle
Inventor: TANAKA TADAO
IPC: B60G17/056
Filed: 1988-12-13
Abstract: PURPOSE:To prevent a sudden variation of car height when an ignition switch is OFF by making the pressure setting of a hydraulic actuator by control valves for a specific period under the condition same as the object car height regulation condition, when the ignition switch is turned off. CONSTITUTION:A control unit 10 controls the current flowing time to control valves 7 by converting an ignition switch 11 ON and OFF. That is, when the ignition switch 11 is ON, the current is started to apply to the control valves 7 when the hydraulic pressure of an oil pump reaches a specific value. On the other hand, when the ignition switch 11 is OFF, the control valves 7 are operated delaying a specific time from the time of the switch OFF. As a result, the current flowing control condition so far is maintained for a specific time after the ignition switch is OFF. By such a constitution, a sudden variation of the car height owing to turning OFF of the ignition switch is prevented.

Title: Method for sorting packaged component on mounting line
Inventor: KAWAMURA TATSUYA
IPC: B65G47/51
Filed: 1992-11-25
Abstract: PURPOSE:To reduce working hours and labor, and to improve reliability by automatically sorting packaged components to each mounting machine. CONSTITUTION:Concerning each mounting machine 2 of a mounting line 3, interference between components and between components and a mounting nozzle and a mounting chuck of a mounting machine is taken into account, in view of a mounting location of the components, relative to results of sorting based on a limitation and a service condition of the mounting machine for each packaged component. If there is interference, the packaged components are re-distributed so that they are not subjected to interference. The re-sorting leads to a superior tact balance, and adjustment is carried out again with allowance for interference in such a way that balance is attained.

Title: Protecting method for interpreter type basic program
Inventor: OGATA AKIATSU
IPC: G06F21/12
Filed: 1987-12-10
Abstract: PURPOSE:To intensively protect a program by searching a space formed between the instruction execution codes via an interpreter type BASIC program stored in a memory and closing said space code. CONSTITUTION:When it is confirmed that a program is stored in a memory, the first text is taken out and a space code is searched at and after the head of a text execution sentence. When the presence of the space code is confirmed, the program following the space code is moved forward (closed) by one byte on a memory address. This operation is repeated until the end of the text. Thus the correction of the program is difficult even though the program is loaded in the memory together with display of a list since the space code is closed.

IPC: B41C1/00
Filed: 1990-11-20
Abstract: PURPOSE:To obtain a printing plate available for producing of quality picture with simple and quick dry processing applied by a method wherein a polymerizable layer is selectively polymerized to form an image of polymerized and unpolymerized parts on a support body, powder is deposited on viscous unpolymerized parts, and furthermore the unpolymerized parts are polymerized. CONSTITUTION:An original plate 5 for printing is prepared, for instance, by forming a ploymerizable layer 2 containing a polymerizing compound and photopolymerization initiator over a support body 1. It is desirable to provide an oxygen barrier layer 3 over the polymerizable layer 2. The polymerizable layer 2 is exposed through a mask 4 to light containing wavelengths which the photopolymerization initiator absorbs, and thereby latent images are made up of polymerized parts 2-a and unpolymerized parts 2-b. Then the oxygen barrier layer 3 is peeled off and powder 6 is scattered only on the unpolymerized parts 2-b which are viscous. The surface on which the powder is scattered is then exposed all over to the same light source as before so that powder particles 7 buried entirely or partly in the unpolymerized parts are fixed by polymerization of the polymerizing compound. Surplus pulverulent bodies are removed, and thereby the printing plate is made up.

Filed: 1987-12-15
Abstract: PURPOSE:To prevent an oscillation phenomenon generated with a flow-through current by inserting a resistor between a drain of p-type MOS transistor and a drain of n-type MOS transistor on a CMOS gate preceding a final output stage of a comparator. CONSTITUTION:The title circuit is constituted in such a manner that an output of the comparator 22 to compare the voltage of a reference voltage part 21 and a voltage divided by a bleeder resistor 23 is inputted to the CMOS gate of a 2nd amplifying part 25 through a 1st amplifying part 24, and this output is inputted to the CMOS gate of a final amplifying part 26, where the output is taken out as an output 6. The flow-through current in p-type MOS and n-type MOS transistors 11, 12 is sufficiently decreased by inserting the resistor 13 between the drain of the p-type MOS 11 and the drain of the n-type MOS 12 on the 2nd amplifying part 25. A fluctuation of the input voltage is thereby kept down to a hysteresis voltage caused by a transistor 18 or lower, and the oscillation of the comparator can be prevented.
