Abstract: PURPOSE:To perform measurement highly accurately without the effects of the dot size, pitch or the like of a light emitting array by receiving the data of a photosensor when the image of the measuring dot of the light emitting array is located at a position which is not rejected by a slit all the time. CONSTITUTION:The dot size of a light emitting arrays 1 is made to be (a), and the dot pitch is made to be (b). The magnification of an objective lens is (m). For example, images 6b - 6d are shown on the imagery surface of dots 1b - 1d. A slit forming member 3 having a slit 4 whose width is (c) is provided on the imagery surface such as this. A photosensor 5 is provided at the rear side of the member 3. When the lens 2 and the light emitting array 1 are realtively moved at an equal velocity (v), the image 6c of the light emitting dot 1c is moved at 2 velocity (mv) in the vicinity of the imagery surface. The next image 6b arrives at the center of the slit 4 after a specified time. When the image of the measuring dot of the light emitting array is located at a position which is not rejected by the slit 4 all the time, timing is controlled so as to receive the data of the photosensor.

Abstract: PURPOSE:To reduce variability of processing condition, by a method wherein a substrate to be processed is contacted directly with cooling gas. CONSTITUTION:A target electrode is set at lower section, and a cooling gas conduit that has a jet nozzle 15 is connected to a vacuum container 14 that has an etching gas conduit 12 and exhaust pipe 13. Pressured cooling gas is gusted into an etching room 14 through the jet nozzle 15, causing collision of cooled gas due to Joule effect against the substrate 17, to cool it. As the cooling gas is directly released in the etching room 14, some composition consisting of the same as the etching gas or the main composition of the etching gas must be used as cooling gas in order not to exert influence on the etching. The quantity of the gas must be less than one tenth of the etching gas. In addition, the quantity of the cooling gas should be reduced by gusting it intermittently. The jet nozzle must be faced directly towards the center of the substrate 17. The distance S from the nozzle to the substrate 17 must be covered enough not to generate temperature profiles.

IPC: B60L9/16
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To enable effective use of adhesion at all times by swiftly detecting slip and skid using estimated time differentiated values of tangential force and promptly performing readhesion control. SOLUTION: A tangential force Ttrh and a time differentiated value Tdrh of the tangential force are estimated, and the estimated value Ttrh of the tangential force is input to a commanded torque generator 2, and the time differentiated value Tdrh of the tangential force is input to a torque reduction start signal generator 3. Based on the estimated value Ttrh of the tangential force, the commanded torque generator 2 outputs a torque Tcz which is slightly higher than the estimated value as a torque command value. As the result, the sliding speed is gradually increased and enters a slip-skid region. Meanwhile, the torque reduction start signal generator 3 detects when the input time differentiated value Tdrh of the tangential force has become negative and generates and outputs a torque reduction start signal Sdn to a reduced commanded torque generator 4.  The reduce command torque generator 4 generates a reduced torque command δTc and controls so that the wheels in the slip and skid range for re-adhesion.

Abstract: PURPOSE: To make it possible to check a head with simplicity and accuracy, in a label printer in which numerous heads are arranged on a lateral row, by printing stripes by heads on the both ends and also printing a checker-like pattern in the middle.  
     CONSTITUTION: Stripe-like patterns 2 and 3 (including dotted lines) are printed by continuously or intermittently operating heads 1a and 1z on the both ends of a label printer in which numerous printing heads 1aW1z are arranged on a lateral line, and at the same time, by operating printing heads 1bW1y located between the patterns 2 and 3, checker-like patterns 4 and 5 or teeth-like patterns 7 and 8 are printed. In the case of printing the checker-like patterns, adjoining parts, of the checker-like patterns 4 and 5 are overlapped and thus overlapped pattern 6 is also printed at the same time. When such a checker-like pattern is printed on a label, in case if there is a head which did not operate, that part becomes a line of label color, and therefore, it can be detected with simplicity.

Title: Plasma ashing apparatus
Inventor: IKEGAMI KOJI
IPC: H01L21/302
Filed: 1986-07-15
Abstract: PURPOSE:To detect a moisture irrespective of a temperature in a reaction chamber and to inexpensively obtain a dry etching apparatus by detecting the end point of a photoresist ashing by an absolute moisture sensor, such as a moisture sensor. CONSTITUTION:A photoresist coated and cured on a wafer 2 is represented by CXRY, and a chemical reaction is generated with oxygen radical 0* excited by a high frequency discharge in a reaction chamber 1. That is, the photoresist is converted to gas of carbon dioxide and steam and removed, and when the photoresist ashing is completed, the generation of the steam is eliminated. Thus, the moisture is high on the way of the photoresist ashing, and when the ashing is completed, the moisture is reduced. Accordingly, the end point of the photoresist ashing can be detected as the invertion of the output of a comparator 23 by suitably setting a reference voltage Vre applied to the comparator 23. Thus, a system controller 20a stops the application of the high frequency power, the introduction of O2 gas and evacuation of vacuum.
