Abstract: An oxidation treatment apparatus for metal pipes, adapted to carry out the passivation of metal pipes used for, especially, a super-clean gas piping system and an ultra-high vacuum apparatus. A holding portion of a retainer is made tubular, and a tapering section is provided on the outer circumferential surface of the holding portion, the retainer being further provided with a spring so that it can be displaced. Therefore, even when the stainless steel pipes vary in inner diameter, they can be retained easily in the holding portion. Even when the stainless steel pipes vary in length, the retainer is pressed constantly against a stainless steel pipe being treated. The oxidizing gas diffused outward from a pipe being treated can be discharged to the outside of the oxidation treatment furnace without causing the gas to touch the pipe.

Abstract: Il est proposé un système pour la surveillance du bon fonctionnement d'un dispositif de chauffage de sonde qui se compose d'un chauffage de sonde, d'un dispositif alimentant le chauffage de sonde avec la puissance électrique nécessaire, ainsi que des lignes d'amenée correspondantes. L'essence de l'invention consiste en ce que le courant de chauffage pour un chauffage de sonde provoque sur une résistance de mesure mise en série avec le chauffage de sonde une tension de mesure qui sera comparée avec une autre tension, laquelle est émise par un élément de référence. Ce dernier se trouve à une température proche de celle de la résistance de mesure ou bien reçoit un signal de mesure correspondant à la température de la résistance de mesure, et il émet une tension qui présente une courbe de température similaire à celle de la tension de mesure. La comparaison de ces deux tensions permet de déterminer le courant traversant le chauffage de sonde et par conséquent le bon fonctionnement du chauffage de sonde, sans qu'il soit nécessaire de monter une résistance trop élevée en série avec le chauffage de sonde.

Abstract: A device or method of the invention provides, or utilises, a sheet 5 of material which when used with a damp backing 4 for wiping of a surface to be cleaned collects dust and grit from that surface in a smear-free fashion. The material of the sheet 5 is non-absorbent, at least over a portion of its thickness providing the wiping surface 5b, and is porous with the property that dampness from the backing 4 permeates the material only so as to provide a vapour state at the surface being wiped. As a result of the vapour state the wiped surface is not damped or wetted in a manner which leaves smears - so far as the surface is concerned the effect is as with a dry wipe whereas so far as the dirt collection is concerned dust and grit adheres to the sheet more in the manner of a wet wipe material.

Abstract: Apparatus for electrostatic clamping of a workpiece such as a semiconductor wafer in a vacuum processing chamber wherein an ion beam is applied to the wafer is provided. In one embodiment, the apparatus includes an electrically conductive platen, a resilient, thermally-conductive dielectric layer affixed to the platen and one or more conductive wires positioned on the clamping surface. The wires protrude at least slightly above the clamping surface except when the wafer is clamped thereon. A clamping voltage is applied between the wires and the platen to firmly clamp the wafer against the clamping surface and depress the wires into the resilient dielectric layer. The clamping voltage preferably comprises a bipolar square wave in the frequency range of less than one Hz to 300 Hz and having a switching rate of about 1000 volts per millisecond or less to limit charging current to the wafer and thereby prevent arcing. In another embodiment, a three-phase wafer clamping apparatus includes a platen divided into three electrically-isolated sections. One phase of a three-phase clamping voltage is connected to each of the platen sections. In the three-phase configuration, the wafer charging current is very small, and the clamping force is essentially constant.

Abstract: In a lens colouring or tinting method, the provision of a sample colour is avoided by converting spectral information concerning the colour desired into numerical information at the optician's shop. This is transmitted on-line to a host computer 3 by a terminal device 2 at the shop. The host computer processes the information and passes it to a dyeing prescription calculating computer at a dye plant from which a dyeing prescription is printed out by a printer 5. A photospectrometer 1 is used to determine transmittance over a range of wavelengths. The differences between these and the transmittances of the lens material are calculated and a concentration number obtained. By combining the relative intensity characteristics of various dye baths, this concentration may be achieved to set up the desired dyeing prescription.

Abstract: The method of threshold triggering of a transmission signal E consists in allocating two triggering threshold values S1 and S2 for the rise and fall of the signal E and in enabling triggering on each of the two threshold voltages S1 and S2. The threshold circuit comprises two threshold amplifiers A1 and A2 receiving the same transmission signal E. The output paths V1 and V2 of the amplifiers are selected by a multiplexer MUX (14), itself controlled by a pilot circuit CP (16). The thresholds S1 and S2 of the amplifiers A1 and A2 are chosen fairly near the "high" and "low" levels respectively of the signal E. The invention is especially advantageous in combination with a signal transmission line between CMOS integrated circuits of VLSI type, or with highly capacitive links. <IMAGE>
