Abstract: A conducting layer such as an additional wiring pattern or an electromagnetic insulation layer is formed on a conducting surface such as of a printed circuit board with an insulating layer being interposed therebetween, by a method which includes the steps of:
     (a) providing a liquid thermosetting composition containing an epoxy resin, a curing agent, a polymerizable compound having at least two acrylate or methacrylate groups and a photopolymerization initiator;   (b) applying the composition to the conducting surface to form a coated layer;   (c) irradiating actinic light on the coated layer to polymerize the polymerizable compound and to obtain a solid, thermosetting layer,   (d) heating the thermosetting layer to cure the epoxy resin and to form the insulating layer; and   (e) forming an electrically conducting layer on the cured resin layer.   
     Steps (b) and (c) are repeated until the solid thermosetting layer has a desired thickness. Step (d) may be performed before or after step (e).

Abstract: The width (11) of the yarn set (10) of a warping machine (2) is continuously monitored with the aid of a line camera (25). The measured width is compared in a processor (32) with a stored target value, and deviations form a control signal which activates a control motor (35) on the warp reed (9). This ensures continuous yarn set width control at full winding speed. …<IMAGE>…

Abstract: An apparatus and method for growing semiconductor quality oxide thermal layers on semiconductor wafers fast enough to be economically feasible as a single wafer process system. Process speed is insured by high pressure and high temperature. For example, if the pressure is about 100 atmospheres (1,500 psi) and at a temperature of 900°C, approximately 2.66 minutes are required to grow a 5,000Å oxide layer in a steam environment. The system can reach these operating conditions from ambient in approximately 30 seconds and depressurization and cool down require approximately 60 to 90 seconds. The apparatus includes a processing chamber to be pressurized with an oxidant, such as high pressure steam. The process chamber is contained in a pressure vessel adapted to be pressurized with an inert gas, such as nitrogen, to a high pressure. A pressure equalizing scheme is used to keep the fluid pressure of the process chamber and the pressure of the fluid pressure vessel substantially the same. The pressure equalization permits the use of thin walls for defining the process chamber.

Abstract: When cutting rod-shaped workpieces into discs using an internal hole saw, the saw blade often deviates from its desired position in the axial direction during the sawing operation, which ultimately leads to products with geometric defects. According to the invention, the deviation can be compensated for by the workpiece and the clamping system of the saw blade performing an appropriate translatory axial relative movement in accordance with the measured deviation. This movement is conveniently controlled via a computer which compares the actual position and the desired position of the saw blade with one another. The method can be used in particular in the sawing of semiconductor rods.

Abstract: A portable hammer machine comprises a cylinder (11) in which a reciprocating drive piston (40) via a gas cushion in a work­ing chamber (44) repeatedly drives a hammer piston (15) to impact on and to return from a tool (20) carried by the ma­chine as soon as a feeding force is applied via the machine housing (10) to the tool (20) under compression of spring means (23) interposed therebetween. The cylinder (11) is on the one hand provided with primary ports (45) for the passage of gas to and from the working chamber (44), which ports (45) at impacting are opened above the hammer piston (15) to venti­late the working chamber (44), and on the other hand with secondary ports (46) for ventilating the volume (47) below the hammer piston (15) during its reciprocation and impacting. The spring means (23) are pre-compressed in the machine hous­ing (10) so as to balance the weight of the hammer machine when the latter is kept standing on the tool (20) with the hammer piston (15) resting against the tool (20). In such position the primary ports (45) are disposed above the hammer piston (15), and their total ventilating area and distance above the hammer piston (15) are chosen such as to maintain the hammer piston (15) idle irrespective of the operating frequency of the drive piston (40), while bringing the hammer piston (15) into repetitive impacting work in phase with a selected drive piston frequency in response to an application of a feeding force on the hammer machine and a resultant dis­placement of the hammer piston (15) from the idle position thereof towards the primary ports (45).

Abstract: 2.1. A moulding of plastic material having thin-point and thick-point regions is to be shaped by moulding a melt injected into the mould cavity 5 of a mould by use of a pressure gas in such a way that, in particular, the transitions from the thick-point regions to the thin-point regions 16, 17 can be cleanly moulded in the correct shape without flow marks. 2.2. The thick-point inner spaces, corresponding to the thick-point regions 14, 16, of the mould cavity 5 of the mould 1 can be changed in their volume by means of an additional tool 4, acting in the manner of a torpedo. Before final shaping of the melt to form the moulding, the thick-point inner spaces of the mould are significantly smaller than after completion of the shaping process. 2.3. The method according to the invention and the apparatus for carrying it out can be used for example for lining sections, arm rests and the like in automobile construction, but also for furniture parts such as table tops, back rests, etc., as well as in all other conceivable application areas in which plastic injection-moulded parts of extremely different cross-sectional forms having thick-point and thin-point regions are used. <IMAGE>

Abstract: In a method for testing the sealing of the individual cells of a battery, the pressure drop is measured that occurs when pressure is applied for a short time. The pressure drops of the individual cells are different, to be precise they are greater for the external cells than for the central cells. Their behaviour describes a curve which can be approximated to by a parabola. The comparison between the values measured on a battery with the values specified for the battery type permits quality control.

Abstract: A fast technique for transferring units of data between transaction systems in a shared disk environment. The owning system, having updated the page, generates a version number for the page which is stored with a lock possessed by the owning system. When a requesting system seeks a record on the page, its request for a lock illicit an indication that a more recent version of the page is required in the local memory. The buffer management component of a DBMS, with assistance from the lock management, triggers a memory to memory transfer of the page from the owning DBMS to the requesting DBMS using a low overhead communication protocol. The transfer of page is without disk I/O or the log I/O for the updates made to the page.
