Abstract: A multiple ratio gear box has two coaxial input drive shafts (38,44), driven directly by a drive motor (26). Each of these input drive shafts can be coupled directly to an output drive shaft (54), located coaxially with respect to the input drive shafts, via a clutch device (56). In addition, the outer input drive shaft (38) is provided with gear wheels (46,48) which can be connected in a known manner, for drive purposes, via a reduction gear (58,60,62,56) to the output drive shaft. In this manner, speeds from about 200 to 5,000 rpm can be generated on the output drive shaft (54) with gear ratios which do not exceed the ratio of about 3 to 1. The speed regulation of the drive motor 26 in the range from about 3 to 1 allows a speed range on the output drive shaft (54) of about 60 rpm to about 5,000 rpm to be represented. <IMAGE>

Abstract: In certain processes for depositing uniform coatings of close tolerance thickness on semiconductor substrates, full shell cage type clear fused quartz wafer processing carriers are required. It is desirable to mass transfer wafers from semi standard plastic wafer carriers into these full shell clear fused quartz wafer carriers. This mass transfer operation generally increases yield of devices per semiconductor substrate by reducing damage due to handling and particulate contamination generated during handling. The invention provides a three part clear fused quartz full shell wafer carrier that meets all requirements for processing and is compatible with many mass transfer machines. The invention is specifically applicable to systems used in producing oxide and polycrystaline coatings on silicon wafers where a mass transfer of wafers from plastic carriers to clear fused carriers is desirable.

Abstract: A pipe connector with socket and plug-in part, particularly for plastic pipes, the socket having an entry guide piece, a final guide piece and an expansion, the expansion consisting of a retaining groove for a holding ring and a sealing bracket for a sealing cone of the sealing component which is connected to the holding ring and, in the non-coupled state, converges in the form of a funnel in the insertion direction. On its inner side, the holding ring has a circumferential compression rib which is provided with a chamfer at least directed towards the entry guide piece, which chamfer continues to the insertion-side flank of the holding ring, at an obliquely inclined surface. The holding ring is pressed over the compression rib into the retaining groove, with the aid of the plug-in part, the retaining groove having a trapezoidal cross-section, in the same way as the holding ring. The compression rib is arranged in the insertion direction of the plug-in part behind the centre point of the trapezoidal cross-section of the retaining groove and holding ring and the insertion-side flank of the retaining groove is longer than the associated flank of the holding ring. The sealing cone consists of two sealing lips with a different radial level, between which there is arranged a circumferential spacing annular gap in the non-coupled state. The sealing lip on the pipe-axis side projects beyond the sealing lip on the socket side in the direction of insertion and is bent in the form of a beak to the radial level of the sealing lip on the socket side. <IMAGE>

Abstract: The cleaning compositions of the present invention comprise pyridine or substituted pyridines alone or in admixture with sulfoxides. The present invention is employed to treat integrated circuit modules enclosed in a cap or can. Following treatment the cap or can, which is sealed to the substrate by means of the cured epoxy, can be removed to allow rework. The preferred method of removing the cured epoxy from module substrates is by refluxing in the solution. The cured epoxy is totally removed and there is no attack of the Al-Cu or Sn-Pb metallurgies or chip polyimide passivation. The silicone overcoat material is not removed from behind the chips, eliminating the need to reapply the material after rework.

Abstract: Method and device for measuring the depth of the bottom below a water surface, in particular of the seabed, through echo sounding from a vessel moving over the surface of the water, in which, by means of a transmitter-receiver unit fixed on the vessel and equipped with a measuring probe, ultrasonic pulses are transmitted to said bottom and the pulses reflected by the latter are received, and where the time difference between the transmission and receiving of the same pulse is measured and recorded. 
     A depth sensor fixed to the vessel is fitted to determine the slowly varying depth of the measuring probe, followed by a low-pass filter to filter out high-­frequency interference signals largely caused by rapid waves. The output signal of the low-pass filter is added in a summator to the output signal of the transmitter-­receiver unit. 
     Disposed in series with the output of a heave compensator added to the transmitter-receiver unit is a high-pass filter for filtering out the low-frequency decay in the integrated signal of the heave compensator, caused by the compensation. The output signal of the high-pass filter is added in the summator to the output signals of the transmitter-receiver unit and the low-pass filter of the depth sensor.

Abstract: A low actuation pressure bar vent (10) for use in a tool string having low pressure therein, includes a body portion (12) and a piston (14) slidingly disposed in the body. The piston and body define a first cavity (68) therebetween and a second cavity (70) therebetween, spaced from the first cavity. The body further defines a plurality of transverse ports (58) therethrough providing communication between a body central opening and a well annulus. When in a closed position (Figure 1), the piston sealingly closes the ports. In a first embodiment, the first cavity has a spring (16) disposed therein. The body also defines a second plurality of ports (72) therein providing fluid communication between the first cavity and the well annulus. Pressure in the well annulus and the spring bias the piston toward an open position uncovering the ports. In an alternate embodiment, a pressurized gas biases the piston. The second cavity (70) is filled with a fluid such that movement of the piston is prevented. A break plug (88) is positioned in the piston and includes a shearable portion (92), which when sheared, allows the fluid in the second cavity to be released to the tubing string. The biasing force moves the piston to the open position, displacing the fluid from the second cavity. During assembly, an assembly plug (104) temporarily holds the piston closed.

Abstract: A process for fabricating a multiplicity of semiconductor devices comprises the steps of applying electrodes (14', 16') to both faces of a semiconductor wafer, and mounting the semiconductor wafer to a substrate (18) by means of an intervening layer of wax (20) which bonds to the substrate and to the wafer. The wafer is then divided by grooves which extend through the wafer and at least partially through the layer of wax. The grooves are filled with a flexible resin (28) that bonds to and passivates the edges of the chips, and the resin is subsequently cured. Next, the wax is removed from the cured resin and chips to provide a discrete flexible unit separate from the substrate. The discrete unit is divided into cells, each of which includes one of the chips for subsequent fabrication into a completed semiconductor device.
