Abstract: A magnetic field enhanced vacuum single wafer plasma etch reactor (60) is disclosed. The features of the reactor include an electrically-controlled stepped magnetic field for providing high rate uniform etching at high pressures; temperature controlled reactor surfaces including heated anode surfaces (66 I, 67 I) (walls and gas manifold) and a cooled wafer supporting cathode (72) and a unitary wafer exchange mechanism comprising wafer lift pins (79) which extend through the pedestal (72) and a wafer clamp ring (78). The lift pins (79) and clamp ring (78) are moved vertically by a one-axis lift mechanism (140) to accept the wafer (75) from a cooperating external robot blade (76), clamp the wafer (75) to the pedestal (72) and return the wafer (75) to the blade (76). The electrode cooling combines water cooling (170, 172, 174) for the body (128) of the electrode and a thermal conductivity-enhancing gas parallel-bowed interface between the wafer (75) and electrode (72) for keeping the wafer surface cooled despite the high power densities applied to the electrode. A gas feed-through device (175, 176, 178, 180) applies the cooling gas to the RF powered electrode (72) without breakdown of the gas. Protective coatings/layers (811, 83) of materials such as quartz are provided for surfaces such as the clamp ring (78) and gas manifold (80). The combination of these features provides a wide pressure regime, high etch rate, high throughput single wafer etcher (60) which provides uniformity, directionality and selectivity at high gas pressures, operates cleanly and incorporates in-situ self-cleaning capability.

Abstract: Method of producing printing plates by means of a laser beam, said laser beam being scanned by means of a rotating polygonal mirror (32). According to the invention the rotational movement is transferred to the polygonal mirror (32) by means of a magnetic coupling, possible oscillations being dampened by a hysteresis-dampened, i.e. a faraday-dampened, magnetic coupling. The magnetic coupling is formed by intermeshing, radially projecting members, which can be slightly rotated relative to one another and which comprise strong magnets (62) . The resulting rotational accuracy is 6 ppm per rotation. In this manner it is possible to perform a laser scanning at a high speed while maintaining a high accuracy. The rotational shaft of the polygonal mirror (32) is disposed in an air bearing and comprises a cylinder (53) of a relatively heavy material, such as granite.

Abstract: An upright-crosspiece unit is described for the formation of metal shelves, particularly in thin sheet, with perfected means of coupling. The upright mainly consists of a tubular body with polygonal cross-section, on the faces of which at least two series of projections are provided, shaped to resemble a "mushroom", as they are composed on one side by end or "head" of larger cross-section, and on the other, with cross-section smaller or equal to the "shank" which connects the head to the upright body. The end of the crosspiece is correspondingly equipped with at least one series of openings obtained in corresponding positions to the upright projections, each of which presents a part with larger cross-section with wall projecting from the plane of the end of the crosspiece and a part with smaller cross-section suitable to receive, with slight forcing, the shank of one of the upright projections. The upright projections are obtained, for example, by drawing and therefore without removal of material. Furthermore, the shank of the projections is connected to the body of the upright with an undercut, also obtained by drawing, which forms a reinforcement to the stress of the projection. <IMAGE>

Abstract: A lancet unit has a finger plate (1) with an opening (10) and a stiletto (4) with a pointed front end and a rear end (5) upon which an impact may be imparted to make the pointed end shoot out through the opening (10) in the finger plate (1). The stiletto (4) is suspended behind the finger plate (1) in a meandering leaf spring (14, 15, 16) guiding its displacement perpendicularly to the finger plate (1). A tool for operation of the lancet unit is shaped as a pencil and may be loaded by twisting its front end carrying the lancet unit in relation to the rest of the housing (21). A multifunction button (22), which may be pressed or rotated, will when pressed trigger an impact on the stiletto when the tool is loaded; or eject the lancet unit when the tool is unloaded, and will when rotated define the pricking depth of the stiletto. The double press button function is obtained by centering a hammer (30) in the housing (21) when the tool is loaded, which hammer in the unloaded status is oblique in relation to the axis of the housing (21).

Abstract: An alarm apparatus comprises an oscillator circuit (20) which provides an oscillating current to an antenna (A) from where a location (1) to be surveyed is irradiated with electromagnetic waves of in the RF frequency range provided by the oscillator circuit (20). The oscillator and the antenna are slightly mismatched with respect to their resonance frequency so as to avoid the oscillation current to go into resonance. Reception in the antenna (A) of an in-phase reflection of the emitted wave results in a superposition of the currents of the emitted and the received waves and increases thus the RF oscillation current. This current is coupled through a capacitor (C6) to a switch circuit (30) such as to trigger an alarm through actuation of the switch circuit if the RF current exceeds a defined threshold. Due to the arrangement of a non linear resistance energy sink (I) in series with the oscillator circuit (20), the switch efficiency is considerably increased by rapid variation of the supply voltage of the oscillator circuit in response to a variation of the oscillator current due to the action of the non linear resistance of the energy sink (I). <IMAGE>

Abstract: A power supply which senses whether a primary battery is discharging to below a predetermined dead battery level or the primary battery has been removed and the system is operating from an auxiliary battery, which has a lower voltage. When the battery voltage goes below the dead voltage level, the system is in a low power mode and the power supply output voltages are satisfactory, a timer may be started. If the battery voltage does not drop to the auxiliary battery voltage level within a predetermined time, a shutdown signal is generated and the power supply ceases providing output voltage levels. In this manner the primary battery can be removed and the system can continue running on the auxiliary battery until a charged primary battery is installed and yet the primary battery discharge rate will be greatly slowed when the primary battery voltage is below a given level and the primary battery is still installed in the system. <IMAGE>
