IPC: H01L21/331
Filed: 1991-01-11
Abstract: A method of making a bipolar transistor comprises forming a buried layer 5 and an epitaxial layer 6 on a silicon substrate, forming a well region 10 by ion implantation in the epitaxial layer, forming a diffusion layer 17 in the well region. forming a base region by ion implantation, depositing an oxide layer 21, forming a contact window by etching the oxide layer, forming a polysilicon layer by a temperature ramp-up process, forming an emitter region by ion implantation and forming the base 27 and emitter 28 simultaneously by diffusion of the implanted impurities. The contact window for forming the emitter is formed by reactive ion etching the oxide layer and the substrate surface damaged during the etching is subjected to plasma enhanced C.V.D. The polysilicon layer is then deposited by ramping up the temperature in the deposition apparatus to prevent the formation of oxide, thereby ensuring that the emitter resistance is kept low. <IMAGE>

Title: Optical switch and method for producing the optical switch
Inventor: TAKIGUCHI TOHRU
IPC: H01S5/50
Filed: 1994-01-25
Abstract: An optical switch includes a semiconductor substrate (1) having a surface, a ridge waveguide (2A, 2B, and 2C) on the surface of the semiconductor substrate (1) and including an optical waveguide layer of MQW structure and first and second cladding layers sandwiching the optical waveguide layer and a switch (30a or 30b) in a part of the ridge waveguide (2A or 2C). A part of the MQW optical waveguide layer included in the switch is thicker than the other part of the optical waveguide layer, whereby the energy band gap of the optical waveguide layer of the switch (30a or 30b) is smaller than the energy band gap of the other part of the optical waveguide layer and larger than the energy of said signal light. Therefore, the absorption loss of the signal light travelling through the optical waveguide layer is reduced. <IMAGE>

Title: Fraud-resistant print-wheel setting mechanisms for postage meters.
Inventor: GILES CHRISTOPHER MICHAEL
IPC: F16H19/00
Filed: 1994-02-16
Abstract: In a print-wheel setting mechanism of the kind in which a reciprocable toothed driving member [e.g. a rack (14)] drives a print-wheel driving pinion (10), an endmost tooth (16') of one component is of reduced height and meshes with a complementary root (12') of reduced depth on the other component. If a fraud (of the kind in which the mesh of the drive component and pinion is displaced by one or more teeth) is attempted, the mismesh of a full sized tooth with the undersized root will prevent the driving component from being set back to the zero position during intitialisation (i.e. prior to a value setting operation) thereby rendering proper operation impossible. The apparatus may be rendered wholly inoperable by the resulting jam. <IMAGE>
Patent GB-2276760-A (GB)
Title: Particle-beam generator, e.g. for LC/MS interface
Inventor: WHITT ROBERT T
IPC: G01N1/00
Filed: 1994-03-10
Abstract: A particle-beam generator, e.g. for a LC/MS (liquid chromatography and mass spectrometry) system (100), handles aqueous inputs with enhanced efficiency. A carrier gas such as helium from a source (112) is passed through organic liquid in a bubbler (116). The organic liquid is maintained at between 0 DEG C and 8 DEG C. The resulting mixture of helium and organic vapor is used as a dispersant gas by the particle-beam generator. The dispersant gas contacts a predominantly aqueous liquid chromatography effluent before a nebulizer (130) causes the effluent to break up into droplets. The solvent in the droplets is vaporized in a desolvation chamber (134). A momentum separator (140) removes helium, organic vapor, and solvent vapor from an analyte particle beam. The analyte particle beam is directed to a mass spectrometer for identification and quantification. Alternatively the beam may be directed to an ion trap or be used to bombard a target. Examples of organic liquid are acetonitrile, isopropyl alcohol, tetrahydrofuran and dimethyl formahide. <IMAGE>

Patent GB-2279215-A (GB)
Title: Increasing the reliability of multiple frequency communication systems
Inventor: COOK MICHAEL WINSTON
IPC: H04B1/713
Filed: 1994-05-26
Abstract: The inherent structure of redundant information fields contained in the message format of a multifrequency communication system determines if the information on the individual frequencies or hops has been degraded due to interference. By detecting bit errors in the received data sequence and identifying the frequencies on which signals representing the bits in error were transmitted, one can block out data from those frequencies on a dynamic basis. The received data sequence is correlated (27) against the possible code words that might have been transmitted. Then, the code word that the receiver decides was transmitted is compared against the received data sequence, bit errors are identified, (29) and also the frequencies on which signals representing the bits in error were transmitted (31). When the error sum exceeds some predetermined threshold (35) present and future data associated with the interfered frequency will be discarded (37). <IMAGE>
