Abstract: A semiconductor device structure includes a region of semiconductor material with a first major surface and an opposing second major surface. A contact structure is disposed in a first portion of the region of semiconductor material and includes a tub structure extending from adjacent a first portion of the first major surface. A plurality of structures comprising portions of the region of semiconductor material extend outward from a lower surface of the tub structure. In some embodiments, the plurality of structures comprises a plurality of free-standing structures. A conductive material is disposed within the tub structure and laterally surrounding the plurality of structures. In one embodiment, the contact structure facilitates the fabrication of a monolithic series switching diode structure having a low-resistance substrate contact.

Abstract: A treating apparatus and method of the present invention carry out dyeing, scouring, bleaching and other treatment for feeling of a textile fabric by transferring and circulating the textile fabric with jetting force of air and liquor using an air jet flow type apparatus which is equipped with a fabric treating passageway in circular form comprised of a transferring passageway and a residence chamber both ends of which are jointed to one another, and perform a series of treating operations such as charging fabric, raising and holding of temperature at a constant degree, cooling and drying more efficiently in a short time. The exit section of the residence chamber is located at a position lower than the entrance section of the chamber, close to the ground on which the apparatus is installed, whereby charge and take-out of a textile fabric is facilitated.

Abstract: A process and apparatus for automatically weighing and introducing chemicals are intended to automatically weigh the chemicals and introduce the chemicals into a treatment tank; the chemicals are injected into a chemical container and weighted, and then transported to a dissolving tank adjunct to the treatment tank, and then introduced into the dissolving tank. A control means is provided to put under its control the operations of injecting into a chemical container a desired amount of desired chemicals selected from among plural sorts of chemicals and driving a transportments and an introducing means automatically in association with this injecting operation.

Abstract: A continuous method of rapidly and uniformly treating textile fabrics in an endless loop configuration. The endless loop is continuously advanced longitudinally so that runs advance successively through a residence bath, for wet treatment in a treating liquor, contained in a partially filled elongated, tubular vessel and increasing gradually in depth in the direction in which the textile fabric is advanced in zigzag form. Suction is taken on the residence bath for piling control of the textile fabric therein and to develop a jet flow of treating liquor therefrom flowed in an enclosed path outside of the residence bath through which the textile fabric is rapidly transferred substantially zigzag free from one end of the residence bath and back to the other immersed in the jet flow liquor as the treating liquor is recirculated by return to the residence bath.

Abstract: An apparatus for the liquid flow treatment of fabrics in which a fabric is set in the form of an endless rope and the fabric and a treating liquid are circulated to effect the liquid flow treatment, the apparatus comprising a lateral cylindrical fabric reservoir tank for storing and delivering the fabric, which tank has an inclined rear portion so that the depth of the treating liquid is gradually increased in the direction of advance of the fabric, a header portion arranged above an inlet part of the tank and provided in the interior thereof with a fabric driving reel or roll for pulling up the fabric from the tank, a treating liquid jet nozzle connected to an outlet part of the header portion to generate a stream of the treating liquid, a fabric delivery tube extended from the jet nozzle to a fabric inlet part of the rear portion of the tank to deliver the fabric substantially linearly together with the treating liquid stream generated by the jet nozzle, a fabric-expanding plate which is arranged so that th

Abstract: Very efficient and economical treatment of textile material in a continuous loop can be carried out in an improved circular treating passageway comprised of a portion for allowing the transient residence of the textile material while transferring in an approximately horizontal position, but in a zigzag form, in a treating liquor and another portion for moving the textile material through a rapid flow of the treating liquid, wherein the residence portion is inclined so that the depth of the treating liquor increases gradually in the advancing direction of the textile material and a baffle plate is provided so that the textile material transferred with the rapid flow of the treating liquor strikes against the baffle plate at a high speed.

Abstract: A bearing wear detector for an AC rotary electric instrument such as an electric motor or a generator in which more than three detecting coils are mounted around a core of the electric instrument having poles of three or not three multiples at a relative space angle and the detecting coils are connected in series to obtain a resultant voltage.
