Title: Fluorescent lamp device
Inventor: MISONO KATSUHIDE
IPC: H01J61/56
Filed: 1990-05-31
Abstract: PURPOSE:To achieve long life of a lamp without reducing the emission efficiency by properly controlling a cathode descending voltage of a pair of electrodes of a fluorescent lamp to an optimal value. CONSTITUTION:When a fluorescent lamp 2 is lighted, a lamp voltage is applied between a pair of electrodes 3a and 3b from a lighting circuit 3, and the lamp is preheated. An arc discharge is then formed, and since an ultraviolet ray is generated by exciting a quicksilver atom, a fluorescent film is excited, and a visual light is thus emitted. The cathode descending voltage of each of electrodes 3a, 3b is detected by each of cathode descending voltage detection circuits 9a, 9b through each of probes 6a, 6b, at every negative semi-cycle of the voltage to be applied at the time. The voltage is compared with a voltage set by a controller 10, and a control signal is sent to a circuit 3, and by controlling a preheating current given to the electrodes 3a, 3b, the long life of the fluorescent lamp 2 can be achieved.

Title: Automatic work device
Inventor: FUJIOKA SHINGO
IPC: H05K1/02
Filed: 1986-06-18
Abstract: PURPOSE:To prevent a board from being accidentally defectively manufactured by arranging both a means for reading information of work contents from a workpiece on which the information is displayed and a means for applying the work to the workpiece based on the information read. CONSTITUTION:While a camera 5 detects a displacement amount between a component mounting position instructed and a contact point pattern 2, the camera also reads information of the component to be mounted such as its name from a set of bar code in the central part of the contact point pattern 2. A control device of a robot 7 then processes the name of a component to be mounted included in the instructed information of the bar code 3 and changes the name into information of a supply position of an IC supply device 6. If an i-th supply position out of 1st to n-th supply positions of the IC supply device 6 is selected as a result of said process, an IC holding part 5 is moved from the supply device 6 via a position immediately above the i-th supply position to the i-th supply position so that the IC component is held.

Abstract: PURPOSE:To improve speed change responsiveness by arranging two counter shafts in parallel to an input shaft through a counter shaft selecting clutch and meshing a gear, selected by a gear selecting clutch on each counter shaft, with the gear of an output shaft. CONSTITUTION:Drive torque, input through a torque converter 5 from an engine, is selectively transmitted to counter shafts 3, 4 from an input shaft 1 through gears 37, 35, 36 and counter shaft selecting clutches 6, 7. A forward 1-speed gear, 2-speed gear 9, pinion, reverse 1-speed gear 10 and a 2-speed gear 11, selected by gear selecting clutches 14, 15, are deceleration-transmitted to a gear 13 of an output shaft 2 partly through idle gears 38, 39. Thus improving speed change responsiveness, drive power is transmitted without interruption not only between the first and second speeds but also between the forward and reverse, and work efficiency can be substantially improved.

IPC: G03F7/20
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To improve the positioning precision of an aperture blade for defining the exposure field angle of an exposure light. SOLUTION: The exposure field angle of an exposure light which projects the pattern of a mask M1 on a wafer W1 is defined by a variable aperture 10, constituted of four aperture blades 11. In this case, the exposure light is cast on a pair of light-receiving sensors 14 arranged on the side edge of a wafer stage 1. When the aperture blades 11 are made to advance and the exposure light is cut off, the positions of the aperture blades 11 in the X-axis direction and the ωZ direction (rotational angle) are detected by using the decrease of light-receiving amount of the light-receiving sensors 14. By adjusting the rotational angle of aperture blades 11 with a piezoelectric element 12b, positioning precision of the aperture blades 11 can be improved.

Filed: 1977-11-25
Abstract: PURPOSE: To decrease the using amount of the hydrogen peroxide as well as to increase the exfoliation force by using the mixture water solution of the hydrogen peroxide and thiourea as the exfoliation agent.  
     CONSTITUTION: The photosensitive resin film is formed on the panel inner surface; the resin film is exposed via the shadow mask to cure the photosensitive resin at the desired area of the fluorescent coat; and the uncured part of the resin is removed to make remain only the desired area which is exposed and cured. Then the graphite film is formed on the entire area of the exposed glass panel surface and the residual cured area of the photosensitive resin, and then the graphite film is removed only on the residual cured part of the resin via the exfoliation agent. Thus, the glass panel surface is exposed to complete the black matrix film. In this way, the using quantity of the hydrogen peroxide is reduced with increased exfoliation force by using the mixture water solution of the hydrogen peroxide and thiourea as the exfoliation agent.

Title: Method of forming phosphor screen for color picture tube
Inventor: MIURA SEIJI
IPC: H01J29/22
Filed: 1981-09-09
Abstract: PURPOSE:To prevent generation of fog and form a phosphor screen with high quality by containing boric acid in a photosensitive component that manifests tackiness by exposure with regard to the method of forming a phosphor screen using the optical tackiness method. CONSTITUTION:A photosensitive component that manifests tackiness by exposure/consists of a principal component of double salt with salt halometallate or nonmetallic salt fluoride of a diazo compound and an aqueous solution in which a small amount of polymer, surface active agent, or the like is added to the double salt. A phosphor film without fog can stably be obtained by containing boric acid in a component that contains propyleneglycol alginate, PVA, etc. as such a polymer. That is, since the gelation of polymer is accelerated by adding boric acid when the coat of an optical adhesive component is formed, a hard film can be formed. As a result, a phosphor is hard to adhere to the film and fog is hard to generate so long as a deliquescent substance is not generated by exposure.

Abstract: PURPOSE:To make the intensity of an ion beam radiated onto a sample so that the sample may be polished over its wide field by forming a tapered place in the edge of an opening in the center of a discoid sheet-mesh so that the ion beam may be prevented from being struck against the edge. CONSTITUTION:A sheet mesh 11 in the form of a disk has an opening 11a formed in its central part, with a sample A placed and fixed on one-side surface thereof so as to cover the opening 11a thereof. A tapered place 11b is formed in the edge part of the opening 11a on the other-surface side of the sheet mesh 11. The tapered place 11b in this case is formed at such an angle that an argon ion-beam B for polishing the sample A may be radiated onto the sample A. When the sample A is polished, the sheet mesh 11 is mounted onto a rotary supporting-body 8, and then the ion beam B is radiated onto the sample A while the supporting body 8 is being rotated. The ion beam B can thus be radiated onto the sample A over its wide surface-field without being struck against the edge part, so that the sample A may be excellently polished.
