Patent EP-0231895-A2 (EP)
Inventor: SATOU YUKIMASA
IPC: H01L29/10
Filed: 1987-01-30
Abstract: The present invention relates to a buried gate type gate turn-off thyristor. A low-resistance layer which is buried in a cathode base layer has a multiplicity of small bores below a cathode emitter layer. The distance between each pair of adjacent small bores and the thickness of the low-resistance layer are each set so as to be smaller than the carrier diffusion length in an anode base layer. In an on-state, carries flow through the low-resistance layer, thereby allowing the low-resistance layer to become conductive, and thus lowering the on-state voltage. A reduction in the dimension of the small bores lowers the resistance of the low-resistance layer and hence lowers the gate drawing out resistance, so that the interrupting capacity is improved. When gate turn-off thyristor is arranged so as to have an amplifying gate structure, the distance between each pair of adjacent small bores in the amplifying auxiliary thyristor section is set so as to be greater than the carrier diffusion length in the anode base layer. In consequence, the on-state voltage in the auxiliary thyristor section is increased, so that the current selectively flows through the main thyristor section, and the auxiliary thyristor section automatically turns off. Accordingly, when the thyristor is to be turned off, it suffices to turn off the main thyristor section alone.

Abstract: A fluidizable catalyst composition is provided containing about 2% to about 8% by weight of copper (about 4% to about 17% by weight of copper salt), from about 0.2% to about 10% by weight of a rare earth metal salt(s), preferably the chloride salt(s), and from about 0.25% to about 2.3% by weight of an alkali metal salt(s), preferably the chloride salt(s), all weight percents based upon the total weight of the catalyst composition. The metals are codeposited on a fluidizable, high surface area alumina support. The weight of the alkali metal employed is not over 2.5% by weight (as the chloride) and the weight ratio of the rare earth metal salt(s) to the alkali metal salt(s) must be at least 0.8:1. Such catalyst compositions are extremely useful as fluid bed catalysts in the vapor phase oxychlorination reaction of ethylene, oxygen and hydrogen chloride to produce 1,2-dichloroethane (EDC). The use of the catalysts results in improved, high percent ethylene efficiencies and high percent HCl conversions, and avoids operating problems caused by stickiness of the catalyst in the fluid bed. A combination of copper chloride, potassium chloride and one or more of the rare earth chlorides on a fluidizable gamma alumina support, produces an excellent catalyst for a fluid bed ethylene oxychlorination process.

Abstract: A structure for interconnecting a timer mechanism (20) driving a cam (66) and a dispensing structure (137, 209) associated with a dishwashing apparatus comprises a cam follower (68) driven by a cam (66) and having a free end that is engageable with a portion of an actuating member (70). In the operating cycle, motion is transmitted from the follower (68) through the actuating member (70) with the actuating member (70) and cam follower (68) moving in a prescribed path in one direction and then in the opposite direction. Abutment means (126, 128) block the movement of the actuating member (70) at its extreme position of travel in the one direction and adjustment means (114, 116, 120) interconnect the follower (68) and actuating member (70) and accommodate relative movement between them until both are in their extreme positions. Thus, by simply moving the cam follower (68) through its path using a manual control knob (24) a precise and repeatable interconnection between the actuating member (70) and the cam follower (68) is achieved.

Abstract: snRNP proteins are isolated, as by immunoaffinity chromatography, using antibodies from a serum sample of a living being affected by systemic lupus erythematosus. The Sm-D polypeptide is in turn isolated from the snRNP protein complex as by gel electrophoresis and electroelution. The amino terminus of the Sm-D polypeptide is then sequenced, and labelled DNA probes with nucleotide sequences complementary to that encoding the amino acid sequence are synthesized. A human cDNA library in a lambda cloning vector is transferred to appropriate filters such as nitrocellulose filters. These filters are screened as by hybridization with the labelled probes to identify the cDNA clones in the library with sequences matching those of the labelled probes. The cDNA encoding the Sm-D protein is then subcloned. The Sm-D polypeptide is then isolated as by immunoaffinity chromatography and, if further desired, as by HPLC chromatography. An assay is then made with the isolated Sm-D polypeptide by reacting the Sm-D polypeptide with a serum sample of a living being to determine whether the living being is affected by systemic lupus erythematosus. The assay may be performed as by an enzyme-linked immunoabsorbant such as anti-human IgG/IgM antibodies covalently attached to an enzyme indicator. Lactoperoxidase/alkaline phosphatase are each an example of an enzyme indicator to indicate, as by distinctive color, an affected person.

Abstract: A single rotating NMR π pulse provides simultaneous spatially-selective inversion or spin-echo refocussing of nuclear spins in two orthogonal dimensions. The two-dimensional spatially-selective pulse utilizes a single RF pulse, with either a square or an amplitude-modulated or a frequency-modulated envelope, and applied in the presence of an amplitude-modulated magnetic field gradient which reorients through the desired dimensions in which selection is desired while the RF pulse is present. These rotating, or "p", pulses are useful for reduction of aliasing signal artifacts in restricted field-of-view high-resolution NMR imaging and, when combined with one-dimensional-localized chemical shift spectroscopy techniques (such as those employing surface detection coils) is especially useful for the production of three-dimensionally localized NMR spectra. Substantial suppression of undesirable residual excited signals, arising from outside the desired two-dimensional spatially selected region, can be obtained by simulated annealing optimization of both the RF and magnetic field gradient amplitude portions of the p pulse and/or by use of surface coil detection. The location of the selected volume is varied by frequency modulation of the RF signal pulse, or by variation of the ratio of currents in the halves of the magnetic field gradient coils.

Abstract: A transistor has a base region in a column (42) of selectively grown epitaxial silicon isolated from adjacent structures in a field of oxide. A layer of doped polysilicon which is embedded in the insulating material surrounding the column of epitaxial silicon forms a sidewall base contact. The collector contact is formed of another column (38) of selectively grown epitaxial silicon grown over and in electrical contact with a buried layer (34) underlying the first column of epitaxial silicon. The emitter region (56) is implanted into the top of column doped as the base region. The base contact can be a buried polysilicon layer or epitaxial silicon which is grown over oxide by uncontrolled growth following controlled selective growth. The transistor can be made by forming a layer of oxide, etching two holes in it and growing the epitaxial silicon in the holes. Thereafter, in one embodiment, the oxide is etched back to expose the sidewalls of the columns and polysilicon is deposited, doped and etched to form the sidewall base contacts. In another embodiment, the base contact is formed by allowing the selectively grown epitaxial silicon to grow laterally out over the top of the oxide layer in the columns of epi are grown. The structure is then planarized, the emitter region is formed, and the contact holes are etched and contacts are formed.
