Title: Method for processing photomask
Inventor: KAWAHARA MASAAKI
IPC: G03F1/68
Filed: 1989-06-07
Abstract: PURPOSE:To improve the accuracy of pattern sizes by a uniform developing and etching by obliquely holding plural photomasks at spaced intervals in parallel with the processing surfaces faced upward and obliquely holding dummy plates at spaced intervals in parallel at the end on the processing side of the array. CONSTITUTION:The photomasks 4 with the processing surfaces faces upward are paralleled and inserted into a mask holder 12 which is so formed as to incline the photomasks 4 and to array and set the same forward and backward at equal intervals. One sheet of the dummy plate 13 is similarly set in front of the foremost photomask 4. A pump 7 for circulation is operated to feed a liquid chemicals 3 through a current rectifier plate 11 in the bottom of a processing tank 5 into the processing tank 5 in the case of the processing with the liquid chemical. The effect of the liquid chemicals on the photomask surface is, therefore, uniformly maintained during the processing with the liquid chemicals, such as developing and etching and simultaneously, the substitution of the liquid chemicals and the desorption of the reaction product on the processing surfaces of the photomasks are rapidly executed. The accuracy of the patterns of the photomasks is improved in this way.

Title: Driving gear of piezoelectric actuator for vehicle
Inventor: HARA YOSHIMICHI
IPC: B60G17/015
Filed: 1989-06-07
Abstract: PURPOSE:To prevent damage and accidental extension-contraction of a piezoelectric actuator or the like by discharging accumulated electric charge in piezoelectric unit in association with a drive voltage output inhibiting means, which inhibits an output of boosted drive voltage, when voltage abnormality is detected. CONSTITUTION:Output voltage of an on-vehicle power supply is boosted in a booster means H2, and drive voltage is applied to the piezoelectric unit HP of a piezoelectric actuator H1 by an applying means H3 to drive the actuator. In driving of the piezoelectric actuator H1, when abnormality of the voltage, boosted in the booster means H2, is detected by an abnormality detecting means H4, a drive voltage output inhibiting means H5 is actuated to inhibit an output of the drive voltage in the booster means H2 and also accumulated electric charge in the piezoelectric unit HP is rapidly and forcibly discharged interlockingly by an electricload discharging means H6. Thus, damage of the piezoelectric actuator and a drive voltage generating source and accidental extension-contraction of the piezoelectric unit due to the abnormality of the drive voltage can be avoided previously.

Title: Member elevation device
Inventor: ITOU HIROMI
IPC: A47L3/00
Filed: 1990-06-05
Abstract: PURPOSE:To adjust height without dropping a member and to achieve adjustment with safety and high accuracy, by supporting the member whose elevation is controlled through pulleys and a rope, and applying frictional resistance suitable for supporting the member to the rope passing the pulleys. CONSTITUTION:A member elevation device engages a container 10 for a window washing detergent as a working member by means of a rope 100. The height of the container is adjusted by vertically moving the rope 100 in a pulley part 8. The pulley part 8 is fixed to one end side of a horizontal arm part 2. The horizontal arm part 2 is supported by vertical post parts 1A, 1B whose interval is adjustable. Pulleys 82 and 83 of the pulley part 8 are pressed to side faces of a protrudsing base part 84 by arbitrary means such as a spring. This pressing force causes frictional resistance to be applied to the rope so that the container 10 can be retained at a constant position, when force is not applied to the rope 100. When it is desired to change the height of the container 10, one of two ropes 100 is pulled down by the height changed by hand, so that the rope 100 overcomes the frictional resistance due to the pressing force and vertically moves.

Filed: 1977-12-07
Abstract: PURPOSE:To improve focussing accuracy and reduce the time of positioning of focus in laser machining in which the detection of focus on the optical axis is necessary. CONSTITUTION:A slope plate 11 with a specified inclination angle theta is put on a loading base 8 which is moved in the direction of horizontal Z-axis (X,Y) as shown by an arrow mark w, and the height d of the lower end upper edge of the plate 11 is also specified beforehand along with the angle theta. On the base 8, a laser machined work is also placed.
