Title: Dry etching apparatus
Inventor: ONUMA HEIICHIRO
IPC: H01L21/302
Filed: 1991-03-19
Abstract: PURPOSE:To enhance the uniformity of an etching operation inside the face of a wafer by a method wherein a lower-part electrode on which the wafer is placed is constituted of an insulating disk and of a ring-shaped conductive disk which has been formed at its circumference and on which the wafer is mounted. CONSTITUTION:An upper-part electrode 1A and a lower-part electrode 3A are constituted respectively of Teflon disks and of ring-shaped aluminum disks 6 which have been formed at the circumference of the Teflon disks 5. The aluminum disks 6 are anodized, and their width is set at 1.2 to 1.5 times of the diameter of a wafer to be mounted. When a high-frequency voltage is applied across the upper-part electrode 1A and the lower-part electrode 3A by using a high-frequency power supply 4, the high-frequency voltage can be applied one hundred percent across the aluminum disks 6. As a result, the unevenness of an etching operation inside the face of the wafer can be improved to 10 to 15% from 25 to 30% in conventional cases.

Abstract: PURPOSE:To avoid mis-operation, by making an idler and a driving source reconnectable, coupling an operating member to a control member controlling this removal, and keeping the neutral position of the idler through the operation of  the operating member for an operating mode other than fast feed and rewinding operations. CONSTITUTION:A solenoid 70 is energized with fast feed operation and reel brakes 64 and 65 for supply and winding are released. A rotating shaft 16 of a drive motor turns clockwise, this rotation is delivered to the 2nd idler 54 in pressing with a roller 60a via the 3rd belt 62 and the 4th pulley 60c to turn the idler 54 counterclockwise. Simultaneously, the 2nd idler support lever 55 supporting the 2nd idler 54 turns clockwise with a slip mechanism to press the 2nd idler 54 on a winding reel pulley 15b and to turn a winding reel 15 clockwise, allowing to wind up a tape 2 in high speed.

Title: Reflection type temperature sensor
Inventor: HIDAKA HIROMI
IPC: G01K11/12
Filed: 1985-03-18
Abstract: PURPOSE:To enable temperature measurement with a high sensitivity and a high accuracy, by inserting the tip of an optical fiber into a through hole of a holder with a reflector arranged at a hollow part thereof while a position compensating member is provided on the back side of the reflector. CONSTITUTION:An optical fiber 11 and a reflector 12 are fixed through a holder 13 and light incident through the optical fiber 11 reaches the reflector 12 without being reflected uselessly. Hence, this reflection type temperature sensor can obtained an intense reflected light from the reflector 12 and receive no noise from any unnecessary boundary, proving high sensitivity. Moreover, the difference in the expansion between the optical fiber 11 and the holder 13 as caused by changes in the atmospheric temperature is eased by a position compensating member 16. Thus, the reflector 13 arranged in a hollow part 15 of the holder 13 is held at the proper position from the tip face of the optical fiber 11 thereby enabling temperature measurement with a high sensitivity and a high accuracy.

Title: Wave step motor
Inventor: MIYAZAWA OSAMU
IPC: F03G7/08
Filed: 1990-03-06
Abstract: PURPOSE:To enable intermittent driving without requiring complex position control and to facilitate determination of stop position by setting the value of displacement, at the time when a rotor is fed intermittently through displacement of vibration mode position, smaller than 1/4 of wavelength in the moving direction of rotor. CONSTITUTION:An electric field is applied onto a piezoelectric element 2 in order to drive the piezoelectric element 2 and to resonate a stator 1. A protrusion 3a stops stably at a node in this state. When the stator 1 moves from a state where the node is shifted by a distance shorter than lambda/4, a rotor 3 moves in the direction 40a and the protrusion 3a moves to a node N and stops thereat. When the position of the node N is shifted by lambda/4, functioning force 41 to the protrusion 3a for the stator 1 functions vertically for the rotor 3 which thereby does not rotate but vibrates unstably in the vertical direction. When the position of the node N is considerably shifted from lambda/4, the rotor 3 moves in reverse direction.

Abstract: PURPOSE:To make a startup control ending timing optimum by detecting an engine load at the time of start, and controlling the operational condition of a speed change step setting means in response to the detected result so as to make an effective time of the startup time control longer as the load is larger, in the tightening force controller mounted on a vehicle. CONSTITUTION:Tighting force of a frictional element provided on a multiple step speed change mechanism 10 is controlled via an oil pressure control circuit 30 by a speed change step setting means 64 so as to set the speed change step to a specified high-speed step, when the startup condition is detected by a startup detection means 65. At this time, engine load is detected by a load detecting means 66 on the basis of a startup detection signal. The detection signal is inputted to an operation control means 67. The startup control time for setting the speed change step to the high speed step is set longer as the engine load is larger by the operational control means 67, in response to the engine load signal inputted therein and then the speed change step setting means 64 is controlled.

Title: Dry etching device
Inventor: YASUDA KOUKI
IPC: C23F4/00
Filed: 1984-03-23
Abstract: PURPOSE:To realize uniform dry etching by covering the surface of a first electrode opposed to a second electrode at least in the periphery of a wafer provided thereon with a material which can reduce etchant and by injecting a reactive gas from holes on the surface of the second electrode. CONSTITUTION:A cover 105 of ultra-high-moledular-weight polyethylene resin is provided on the periphery of a wafer 104 covered with an Al film. A reactive gas principally consisting of BCl2+Cl2 is injected from holes 108 so that plasma of the reactive gas is formed by means of electric discharge. Etchant thus produced is absorbed by the cover 105 and therefore the density of the etchant is reduced on the periphery of the wafer. Accordingly, the density is uniformized in the surface of the wafer. A supporting electrode 102 is intermittently rotated so that each wafer can be always supplied with fresh gas when it is stopped directly under the gas outlet 108. Further, if the gas is supplied to the central portion of the wafer where more etchant is consumed during the etching of Al, the etching rate of that portion can be caused to approximate that of the peripheral portion. Still further, the etching rate can be uniformized among the wafers without being affected by local gas flow within the reaction chamber.

Title: Method for preventing coating-unevenness on flat plate in electrostatic spray coating
Inventor: BANDO RYOTA
IPC: G03F7/16
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent a trouble such as blocking on a coated plate, which is obtained by electrostatic spray coating on a flat plate, by installing a conductive frame with a specified width in the whole surrounding of the flat plate at the time when a coating film is formed on a flat plate by an electrostatic spray coating. SOLUTION: To form a coating film on the surface of a conductive flat plate by an electrostatic spray coating, a conductive frame with 10mm or wider width is formed in the whole surrounding of the flat plate. The width of the frame is preferably set to be within a range of 10-30mm and due to that, the coating film formed on the conductive frame is made to be thick at the time of electrostatic spray coating and the coating film in the peripheral rim part of the flat plate is prevented from being thickened. At the time of installing the frame in the whole surrounding of the flat plate, it is preferable for the frame to be prevented from overlapping the parts of the flat plate to be coated. After electrostatic coating formation on the flat plate, if necessary, drying is carried out and the frame is taken out of the flat plate to give a flat plate coated with a coating film.  The taken out frame is reused after the coating material and coating film are removed by washing.
