Title: Metal organic vapor phase epitaxial growth of group iii-v semiconductor materials
Inventor: KUECH THOMAS F
IPC: C30B25/02
Filed: 1989-05-25
Granted: 1993-02-02
Abstract: ABSTRACT     METHOD ORGANIC VAPOR PHASE EPITAXIAL GROWTH OF III-V                SEMICONDUCTOR MATERIALS            This invention is directed to a method of epitaxial growth by metal organic vapor phase epitaxy (MOVPE) of Group III-V compound semiconductors in a hot wall reactor.  Epitaxy is accomplished by use of precursors having a metal, an organic ligand, and an inorganic ligand.  The system is operated at very low pressures to provide a high throughput of wafers and a highly uniform deposition growth.  The invention is further directed to the use of the class of precursors to selectively grow III-V compounds on a masked substrate, wherein growth occurs epitaxially on the exposed areas of the substrate but not on the surrounding mask.

Granted: 1994-02-08
Abstract: ABSTRACT OF THE DISCLOSURE           A pressure saturator system includes a grooved mandrel and an opposed element which define a converging chamber therebetween.  A web is passed through the chamber with a first side of the web adjacent the mandrel.  A liquid saturant is introduced into the chamber such that the saturant contacts the second side of the web and impregnates the web as the web passes through the chamber.  A gas receiving belt is passed through the chamber with the belt interposed between the web and the mandrel and in contact with the first side of the web.  The belt receives gases and any excess saturant from the first side of the web as the saturant enters the web in the chamber, thereby facili-tating the removal of gases from the web, improving the saturation process, and protecting the mandrel from undesired contact with the saturant.  In alternate embodiments the belt is formed of a porous material or defines an array of gas receiving slots positioned against the first side of the web.

Abstract: METHOD AND APPARATUS FOR MOLDING                   SHOE INSERTS                 Abstract of the Disclosure A method and apparatus are provided for rela-tively  convenient  and efficient production of  custom molded  inserts  for  shoes.   The apparatus utilizes a molding pillow arrangement,  upon which a user stands during use.  The molding pillow arrangement has a com-posite construction including a first resilient layer, a middle resilient layer and a bottom support layer.  The bottom support layer preferably includes a generic arch curve therein.  The upper resilient layer is formed from a relatively soft foam, and thus molds around a user's feet.   The middle layer is resilient,  but relatively hard by comparison to the upper layer.  The middle layer provides for a relatively firm cushion underneath the user's foot, facilitating contouring of a molded insert to the bottom of the user's foot.  Preferably, at least the upper cushion portion of the molding pillow arrange-ment comprises left and right cushions,  independently moldable with respect to a user's left and right feet. A preferred insert construction for use in association with the method and apparatus is provided.

Abstract: A cuvette for holding a liquid to be examined optically has front, back, and side walls defining a rectangular cross section and a Y-shaped structure at the bottom thereof for holding the liquid. The Y-shaped structure extends between transparent front and back walls with an upper funnel mouth extending to the side walls, and a liquid holding portion formed of inner walls spaced between the side walls, and extending down to a rounded, tub-shaped bottom. The front walls are transparent and serve also to form the front and back of the liquid holding portion. The bottom preferably has a frustroconic surface to minimize the amount of liquid required for examination and to facilitate mixing of liquids added to the cuvette. The side walls extend below the tub-shaped bottom, and are joined to the front and back wall midway up the liquid holding portion by means of a rib, so that light is not scattered by the side walls and optical inhomogeneities are prevented.

Abstract: Coherent bands (1) of suction tubes (2) wrapped in individual protective envelopes are used to make possible the mechanical and automatic application of suction tubes to individual packing containers. The bands consist of two strips (7) of flexible plastic material which are sealed to one another and between them enclose the suction tubes. To facilitate the separation of tne suction tubes and surrounding protective envelopes from the band on application to the packing containers, the suction tube band is provided in accordance with the invention with transverse cuts (6) situated between the suction tubes which at their ends lead into further cuts which extend in longitudinal direction of the band or have a certain length in the said direction. The individual protective envelopes entering into the suction tube band are thus held together solely by two parts situated at a distance from one another and extending bandlike between the envelopes which can be cut through comparatively simply on application to the individual packing containers.

Granted: 1993-08-10
Abstract: ABSTRACT   A variable damping shock absorber is disclosed.          The shock absorber has a two-wire electrical lead extending  into the piston rod.   The  electrical energy provided by the lead drives a drive motor, which rotates in alternating directions depending on the setting of an internal switch that switches upon occurrence of voltage spike, which occurs when the motor has driven an internal rotatable valve as far as the valve can go within the confines of rotation permitted by the valving.   The drive motor then drives an internal valve between an open and closed position,  which in turn opens and increases,  or closes or reduces, a path in fluid flow from one cavity to another as the piston moves within the shock absorber.
