Patent CA-2085143-A1 (CA)
Inventor: MARUI TOMOHIRO
IPC: G01B11/06
Filed: 1992-12-11
Abstract: An apparatus for controlling a process, in which a control system is structured by having a direct desired value (for example the film thickness d) as the control target, with an emissivity power ratio Ku * ([the .lambda. i power of .epsilon. 1]/[the .lambda. j power of .epsilon. 2]) used as an indirect desired value, and a measured value of emissivity power ratio Ku obtainable from detection signals (Si (S1, S2, ...) of a radiation sensor (160) used as an indirect controlled variable.  A process manipulated variable (170) is automatically controlled in accordance with the direct desired value (actual film thickness) such that the indirect controlled variable attains an indirect desired value as target.  Thus, the controlling effect of the control apparatus is improved by the use of the excellent control parameter.

Title: Method and apparatus for measuring crimp frequency of a web
Inventor: KAMINER JON J
IPC: D06H3/08
Filed: 1991-07-16
Abstract: A method and apparatus (12) to non-destructively inspect and quantify yarn crimp characteristics (10) either off-line or on-line at speeds in excess of 2,000 yds./min. by acquiring images of yarn crimp on-line during the manufacturing process, then digitizing the images of yarn crimp and performing all data processing from the digital data required. Each image is segregated into features (e.g. valid crimp, low frequency oscillations, high frequency oscillations, edge oscillations, and unconfirmed oscillations) with each parameter being analyzed separately. Features are segmented two dimensionally using techniques such as, but not limited to, local max/min intensity profiles and spatial intensity and frequency thresholding. Regions identified as abnormal are separated from areas of valid crimp before determining crimp frequency.  Outputs of individual analysis are combined to determine global tow quality. This method provides a complete statistical analysis for each lane in the tow as well as the overall tow width. Software analysis allows operator interaction if desired.

Abstract: Champ magnétique (202, 302), permettant de confiner le plasma, généré dans une zone de pulvérisation (105, 106) d'une cible de pulvérisation (40) avec une ligne de champ critique (202b, 302b) qui détermine la forme du plasma (204, 304). La ligne de champ critique est progressivement aplanie pendant la durée de vie de la cible au fur et à mesure qu'elle s'érode. L'aimant (51, 52) comprend de préférence des pôles (57, 61, 65) espacés autour de la partie de la cible située sous la zone de pulvérisation afin de créer un champ magnétique qui s'aplatit au fur et à mesure qu'il perd de son intensité. L'alimentation stabilisée (122) maintient un niveau stable qui est augmenté au fur et à mesure que la cible s'érode afin de conserver un taux de dépôt constant. La tension de l'alimentation électrique est maintenue à une valeur égale ou supérieure à un niveau constant en diminuant progressivement le courant qui alimente un électro-aimant (52, 54) afin de réduire progressivement l'intensité du champ et de l'aplatir. La présente invention permet d'élargir le sillon de la cible et d'accroître la quantité de plaquettes enduites par la cible durant sa durée de vie.

IPC: G01F15/04
Filed: 1993-08-05
Abstract: Abstract of the Disclosure A method and apparatus for determining a volume correction ratio for a gas (12) by measuring the temperature and pressure of sample gas (20) tapped from a pipeline (14) as it undergoes controlled expansion. Sample (20) gas flows through first chamber (22) and mechanical pressure regulator (24), where the pressure of the sample gas (20) is reduced. The pressure decay rate of sample gas (20) is measured in the second chamber (26) and compared to a reference gas (31) pressure decay rate. The volume correction ratio is determined from the rate of change of pressure in the first chamber (22), the absolute pressure of the pipeline gas (12), and the absolute temperature of the pipeline gas (12). The volume correction ratio is used to determine the flowing condition density Pf from a measured base condition density Pb.

Abstract: This invention relates to reading and analyzing the contents of sealed mail.  The invention has utility in the sorting of sealed mail and in the matching of mail envelopes and its contents.  The contents of sealed mail are read by having a light in the near infrared directed to the sealed envelope and creating an image of the printed matter on the contents by directing the light to an optical detector.  The image thus received is analyzed and a determination can be made whether contents are of high value or whether the addresses on the envelope match the addresses of the contents.  If the envelopes are not addressed, the address can be printed on the envelope after analysis of the address block of the contents.

Title: Random access in mobile telephone systems
Inventor: DENT PAUL W
IPC: H04B7/26
Filed: 1993-04-08
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention includes a system and method for minimizing interference between two radio stations, e.g., a mobile radio telephone and a fixed base station, at the initiation of a radio communication.  A mobile station initiates a random access at the lowest power level and increases the transmission power level until the base station detects the access signal.  Once detected, the power level of the message is maintained at the detected level so that the signal interference is avoided.  The present invention also provides a mechanism for synchronizing random access communications between mobile stations and the base station despite variation in distances between the mobile and base stations.

Title: Preparation of peroxyacids
Inventor: WILSON SHARON LESLEY
IPC: A61L2/16
Filed: 1992-09-03
Abstract: Dilute solutions of chlorinaceous compounds have been employed as disinfectants, but it is desirable to find alternatives to them in view of their possible implication in the formation of carcinogenic or otherwise harmful substances. Dilute solutions of hydroxyaliphatic peroxyacids are made by first reacting a satured or near satured solution of the precursor hydroxyaliphatic carboxylic acid with concentrated hydrogen peroxide, preferably employing a mineral acid catalyst, until the concentration of peracid available oxygen (Avox) has attained or nearly attained a maximum and then diluting with water, preferably containing additional hydrogen peroxide and a stabiliser for peroxygen species. By adopting this method, a higher concentration of the more active peroxyacid species can be maintained in the dilute solution without increasing the amounts of hydroxyaliphatic acid and hydrogen peroxide employed. The solutions are available for disinfection, and the other uses of peracids, such as for bleaching.
