Abstract: In order that a plurality of discharge lamps (LL1, LL2), which are connected to a common ballast (10), can be switched on and off separately from one another via external switches (S1, S2), the operating section (BT) of the ballast (10) is connected to the external switches (S1, S2) via decoupling elements (G1, G2). The operating section may be supplied via any of the decoupling elements (G1, G2). A detector (D1, D2) identifies which of the switches (S1, S2) has been closed and closes a switching element (T1, T2) contained in the lamp circuit (LK1, LK2) of the relevant discharge lamp (LL1, LL2) so that only those lamp circuits are closed whose detector (D1, D2) has been triggered.

Abstract: A number of heated injection molding nozzles (10) are mounted along the side surface of a melt conveying manifold (12). In one embodiment of the invention, a connector collar having a tapered flange portion is bolted to the side surface of the manifold to provide each melt bore outlet. Each nozzle has a matching flange portion with a melt bore inlet extending laterally from a side surface. The nozzle is mounted on the manifold by securing the flange portions together by bolting a wedge clamp having two halves over the aligned flange portions. This accurately aligns the inlet with the outlet and allows the nozzle to be rotated to a particular angular position. In another embodiment, a melt conduit member (152) is mounted between the manifold (12) and each nozzle (10). The melt conduit member (152) is clamped to the manifold after being rotated to a desired angular position about a first axis. A nozzle (10) is clamped to the melt conduit member (152) after being rotated to a desired angular position about a second axis (166) which is substantially perpendicular to the first axis. Thus, each nozzle can be located with any desired angular orientation without the melt flowing through an acute angle bend.

IPC: H01L27/02

Abstract: In certain circuits, it is desirable to match the electrical characteristics, (e.g., thresholds), of two (or more) MOS transistors. For example, in an ECL output buffer, a first transistor is a voltage reference, and a second transistor is an output buffer controlled by the voltage reference. However, the orientation of the transistors may affect their electrical characteristics. This may be due to the source/drain ion implantation step that occurs at an angle off the vertical, or other processing effects. The present invention provides symmetrical MOS transistors having characteristics that are independent of orientation. For example, a square gate (11) layout provides both vertical (I 3 , I 4 ) and horizontal (I 1 , I 2 ) current components, thereby obtaining 90 degree rotational symmetry.

Abstract: A pneumatically-pulsed dampening device that allows precise variations in the amount of water transferred to selected regions (zones) on a vibrator roller (21) and ultimately to a lithographic printing plate, blows independently operable and adjustable flat air streams (17) over the upper surface of an open-celled sponge (15) whose lower portion rests in a reservoir of water (11). This results in a linear carburezation of the water on the surface of the sponge into a fine atomic mist which is sprayed on the vibrator roller. Capillary tubes can be mounted before the sponge to insure continued wetting of its surface. A shroud (52) open at one end for allowing spraying of the roller, may also be formed with a baffle to further assure the horizontal contour of the air stream and with a Bernoulli effect capturing device to suck in fugitive mist.

Abstract: An improved technique for inserting variable text or images into shell documents (150) to produce complex reports and form letters. This technique greatly simpli­fies the control structure used to insert the variable data and makes the maintenance and updating of shell documents much easier. To accomplish this, shell documents have common text (20, 24) and at least one variable docu­ment command (152). Variable document commands are per­mitted to have variable fields (154, 156, 158). In this way, variable text or images may be inserted based upon reference to variables stored in variable fields without the need to use conditional instructions in the shell document.

Abstract: An automatic winding and doffing apparatus of a circular knitting machine includes a winding unit (4) that revolves synchronously with the cylinder of the circular knitting machine. The apparatus includes opposed winding apparatus frame arms (16,17). A fabric winding roll (21) has one roll end pivotally mounted on one of the arms. A guide mechanism guides the knitted fabric to the winding roll. The fabric roll is stopped after a predetermined amount of fabric has been wound. A doffing apparatus doffs the fabric from the winding roll after a predetermined amount of fabric has been wound on the fabric roll. In preferred embodiment, the other winding roll end is freely supported by a turning lever (28) pivotally mounted on the frame. Upon pivoting movement of the lever arm, the winding roller may be moved from a home, winding position to an unloading, doffing position in which the other end of the winding roller is removed from the support arm. A lock mechanism operatively connects to the turning lever for locking the turning lever in a position in which the turning lever supports the winding roller in the home, winding position and for unlocking the turning lever to allow the turning lever (28) to pivot and disengage from the winding roller (21).

Abstract: The invention provides an apparatus capable of automatically changing over continuous paper and cut paper, wherein manual changeover is possible even if an actuator is locked in case of an accidental paper jam, to thus facilitate a processing. A platen gear (38) can be associated with a tractor drive gear (28) via a clutch gear (64) for connecting or disconnecting both gears to or from each other upon oscillation of a clutch lever (60). The clutch lever (60) is oscillated by a changeover lever which is moved by a changeover cam (34) driven by a stepping motor (M). Therefore, the changeover cam is manually moved under a normal condition so that the changeover of the continuous paper and the cut paper can be manually performed without any application of a load of the stepping motor (M).

Abstract: A portable cellular radio telephone (1) comprises a transceiver including a voltage controlled variable gain amplifier (11) operable at one of a plurality of predetermined output power levels selected automatically under the control of a microprocessor (4) in response to a signal from a base station indicative of a requirement for a change in level of the output power. A battery save mode can be manually selected which causes the output power at the maximum power level to be reduced to a value below the nominal value of the maximum power level imposed by the system specification. Power consumption is thus reduced when the transceiver is transmitting at maximum power, and battery life is therefore extended. The battery save mode may be selected from a menu which can be viewed on a display (5). The respective menu function can be accessed and enabled/disabled by using the keys (6a, 6b) on the telephone keypad (6). The selection and de-selection of the battery save mode may be accompanied by a legend such as "BATTERY SAVE ON" and "BATTERY SAVE OFF" on the visual display.

Abstract: An electrical system wherein the electrical conductive traces on the circuit boards are routed to achieve a balanced net to reduce noise caused by transmission line reflections. A trace (202,216,248,274) is routed from the source terminal (200,214,236,260) of the net to a balanced junction (204,218,238,288) wherein if there are an odd number of load terminals, or loads, the balanced junction is located at one of the loads (204,238). The remaining loads are grouped into branches wherein each branch includes an equal number of loads. A trace is routed between each of the loads of each branch to serially connect the loads of each branch together, or, a trace is routed from a center one of the branch loads to each of the remaining branch loads, forming subbranches. In an alternate embodiment, a balanced subbranch is developed. The balanced load is connected to a pseudo-balanced load, which further receives an equal number of branches. The 3 pseudo-balanced load is then connected to another pseudo-balanced load, which may also receive an equal number of branches. This pseudo-balanced load is connected to the source. In another alternative, two balanced subbranches have their balanced loads connected to a central balanced load. This balanced load may receive even further numbers of equal branches. The balanced load is connected to the source.
