Abstract: ABSTRACT OF THE DISCLOSURE     An improved method for fabricating an isolated region for dielectric isolated complementary IC is disclosed.  In order to avoid the difficulty of mask alignment and patterning on a deep etched uneven surface of the substrate, the present inven-tion intends to align the pattern before etching.  The etching to form the p-type and n-type islands on the surface of the substrate is done at the same time.  Next on the surface of the substrate is grown a polysilicon layer.  Then the substrate is lapped off from its back surface and removed, leaving the island parts in the polysilicon layer, which becomes a new substrate.

Abstract: ABSTRACT   This invention relates to an implant device.  It is well known in the art that there are various methods for externalizing an internal vessel, or providing fluid communication from the vascular system to a cleansing source outside the body.  In the former, the ulceration of the skin, and in the latter the trauma of connecting and reconnecting arteries and veins with tubes or needles have proved to be serious problems.  The present in-vention seeks to do away with these problems by providing an implant device which connects to an implantable connector in order to provide access to the body conduit or vessel external from the body.  The implant device has a passageway, which is either straight or curved at the outlet, an anchor means for establishing a biological anchor, and a grafting mesh annularly and longitudinally diposed about, and longitudinally spaced apart from, at least a portion of the exterior of said implant device whereby tissue is permitted to grow between the exterior of the device and the mesh.  The passageway, anchor means and grafting mesh are formed from a material se-lected from the group comprising pyrolytic carbon disposed on a graphite substrate and vitreous carbon.

Abstract: Summary:            Process of Molded Parts from Fibrous Material and Fiber Mat for the Manufacture of Molded Parts A process for the manufacture of molded parts from fibrous material, in particular cellulosic fibers, is described. For this purpose a particulate bind-ing agent is introduced into a fiber fill, the mix-ture then precompressed into a fiber mat, subsequent-ly subjected to high-temperature steaming and finally, after preforming as the case may be, molded into the final molded part under the influence of pressure and heat. The binding agent consists of thermoplastic particles incorporating a foaming agent in a state analogous to an alloy which is activated before the molding of the final molded part, preferably by high-temperature steaming, and of a binding agent that cross-links under heat and which is deposited on the particles in the form of a layer.

Abstract: Abstract In a system for measuring torque, torsional vibrations and power, emitters and sensors are arranged on at least one rotating shaft. From one of the frequencies (f1 or f2) of the signals (S1 or S2) of the sensors, a new signal (S3) is generated whose frequency (f3) corres-ponds to the sum or difference frequency of the frequen-cies (f1, f2), and which is phase-locked to the signal (S1 or S2) from which it is generated. The rela-tion of the initial phase of the new signal (S3) with the frequency-generating signal (S1 or S2) is determined also by the other signal (S2 or S1). The signals (S1, S2) and the new signal (S3) are fed to a multiplier. The measure of the torsion-dependent twist of the emitters with respect to each other, from which the torsional vibration signal can be derived, is determined by inte-gration of the signal (S1.S2.S3) supplied by the multi-plier over one or several of the least common periods of the frequencies (f1, f2, f3) or by appropriate filtering.

Diaphragm (34) in the fluid inlet chamber (76) is secured to a piston slidable body (40) extending within inter-mediate fluid chamber (104) and having a valve seat (88) thereon between inlet fluid chamber (76) and intermediate fluid chamber (104).  A second fixed valve seat (64) is provided within the body (40) between the intermediate fluid chamber (104) and the outlet fluid chamber (106).  A valve spool (92) has a pair of O-ring seals (94,  96) thereabout adapted to seal  against the valve seats (88, 64).  Unseating of the O-ring seals (94, 96) from the seats (88, 64) results from predetermined pressure changes in the sensed fluid pressure in fluid pressure chamber (76)  and communicating such pressure changes through a fluid line (22) from the intermediate fluid chamber (104) to the control valve (C).  An embodiment shown in Fig. 11 provides a delayed response to the control valve resulting from pressure changes in the sensed fluid pressure.  The delayed response is obtained by a flow restriction (150) in a  line (148)  from an intermediate fluid chamber portion (144) which is separated by a diaphragm (140) from a balancing intermediate fluid portion (142).
