Patent EP-0226383-A2 (EP)
Inventor: YOKOHAMA NAOKI
IPC: H01L29/08
Filed: 1986-12-02
Abstract: A resonant-tunneling heterojunction bipolar transistor (RHBT) device, having a superlattice structure and a PN junction, includes an emitter layer (17), a base layer (14), a collector layer (13) operatively facing the base layer to form a PN junction at the face between the base layer and the collector layer, and a superlattice structure (16) including at least one quantum well defining a sub-band of energy at which carriers resonant-tunnel therethrough, formed at least in the emitter layer and operatively facing the base layer. 
     The RHBT has differential negative resistance characteristics for realizing a variety of logic circuits and includes an electron resonance and a positive hole resonance, for which the generation condition is changeable in response to a mole fraction of material of the emitter layer. 
     Such an RHBT, unlike a prior RHET, can be made to operate satisfactorily at normal ambient temperatures with adequate current gain.

Abstract: Cutting insert for chip-removing machining comprising an upper face (11), a lower face (12) and, connecting those, edge surfaces (13). Lines of intersection between the edge surfaces and the upper face form cutting edges. The insert (10) has a substrate (14) comprising a metal and a radiation-­emitting material. The substrate (14) is covered by a radiation-tight layer (15). During wear of the layer (15) the substrate (14) is exposed, and therefore the intensity and direction of the radiation can be detected for determin­ation of the size and type of the wear damage.

Abstract: A process for the preparation of an organohalosilane of the general formula: X4-nSiRn in which, R represents a methyl, ethyl, n-propylisopropyl, n-butyl, isobutyl, phenyl or a tolyl functional group; X represents chlorine or bromine; and n is 1, 2 or 3, is disclosed. The process takes place by reacting an SiO2-containing material with a hydrocarbon halide of the general formula RX, in which R and X are defined as above. The reaction between the SiO2-containing material and RX takes place in the presence of iron powder and either: (a) carbon and a catalyst, in which the SiO2-containing material, the iron powder, the carbon and the catalyst are subjected to a heat treatment at 800 DEG  to 1400 DEG C. prior to the reaction with RX or (b) an aluminum trihalide and/or boron trihalide in which the halogen is either chlorine or bromine. Alternative (b) may be carried out in the presence of a catalyst. The organohalosilanes of the invention are useful, for example, as starting materials for the preparation of organopolysiloxanes and as starting materials for the preparation of SiC produced in the gas phase.

Abstract: A disk drive system comprises a magnetic disk apparatus which accurately positions read/write means for reading data from and writing data on tracks on the data surface of a rotary disk on a predetermined track on the disk on the basis of servo data written in the servo area formed on the data surface, and a disk controller which controls the mode of operation of the disk apparatus. Index signals respectively indicating the start and end of the servo area are generated on the basis of the result of detection of the angular phase of the disk. The mode of operation of the magnetic disk apparatus is discriminated on the basis of a write control signal provided by the disk controller. The index signals respectively indicating the start and end of the servo area are sent to the disk controller when the mode of operation is track format write mode, while the index signal indicating the end of the servo area is sent to the disk controller when the mode of operation is other than the track format write mode.

Abstract: There is disclosed a process for selecting half-tone screen systems for use with raster scanned images to ensure the absence of Moire effects when using two or more color separations. Mathematical analysis provides an ensemble of screen patterns which are based on an odd/even relationship between the number of screen "lines" per repeat cell distance for combinations of screens. From this ensemble a critical selection is made of suitable screen parameters for the chosen font(s) using computer integration over repeat cell areas to show which chosen screens give invariance of white fraction with off-set distance in the two directions (horizontal and vertical). This comparison is carried out between all pairs of the required number of screens to be used.

Abstract: A distributing device for chaff choppers for attachment to mowing-threshing machines has a top cover plate, beneath which right and left groups of baffles are arranged next to one another, preferably at right angles to the cover plate. The baffles are pivotably supported around axles at their ends facing the chopper and spaced therefrom, while being rigidly connected by guide bolts penetrating guide slots in the cover plate or in the machine casing. A set bar is associated with each group of baffles. The baffles are connected with each other by the guide bolts which are rotatable in fixed bearings and by two guide rails, and, at their ends facing the chopper, rotatably and displaceably arranged in points on the cover plate. The guide slots of each group extend displaced relative to each other in a transverse direction, substantially parallel to each other and to a line through the axles. The set bars are outwardly inclined to that line and spacing of the guide bolts from the axles decreases from baffle to baffle in correspondence with outward displacement of the guide slots. A set leave is connected jointedly to each set bar, and is articulated in a point spaced from its point of articulation on the set bar on the cover plate. A coupling rod connects the set levers. Thus, the groups of baffles can be adjusted to different extents. The set levers are displaceably connected with the coupling rod and displaceable lengthwise to extents limited by stops.
