Title: Photosensitive devices using semiconductor bodies and optical detectors including such devices
IPC: H04B10/60
Filed: 1963-05-30
Abstract: 1,035,167. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. May 30, 1963 [June 11, 1962], No. 21616/63. Heading H1K. A photo-sensitive device consists of a semiconductor body of one conductivity type and of relatively low resistivity having on one of its faces a mesa whose surface is formed by a thin epitaxial layer of the same conductivity type but of higher resistivity. The minority carrier lifetime in the mesa portion is higher than that in the remainder of the body. A low resistance connection is made to the main part of the body and an electrode penetrating the epitaxial layer is alloyed thereto to form a small area PN junction in the layer close enough to a surface of the device to receive incident radiation. The device may be used as a photo-detector in an optical communication system. In the manufacture described a low resistivity P-type germanium body is polished on one side which is then vapour coated with a thin expitaxial deposit of high resistivity P-type germanium. For reasonable performance it is necessary to have a high minority carrier lifetime in the layer and a low lifetime in the body. It may be necessary to use known methods to increase or decrease lifetime in the various regions. The deposited layer is masked and etched to provide a plurality of mesa, and then to enable the slice to be divided into many wafers. A rectifying connection is made to each individual wafer 11 with a ribbon foil made of gold containing a donor such as arsenic or antimony. The tip of the foil is cut to a sharp point 14, placed against the epitaxial layer 13, and formed with a square voltage pulse so that it alloys about halfway into the layer. The gold in the foil has the additional merit of reducing the lifetime in the N-type germanium alloy formed beneath the foil. The original portion of the wafer is now jet etched to produce a cavity 17 into which radiation is directed during operation of the finished device. During etching the alloy bonded contact may be protected with epoxy resin which may be left permanently to strengthen the device. The cavity may be produced before the point contact is alloyed to the device. In devices in which no cavity is formed the radiation is directed on to the epitaxial layer and is preferably polarized in the plane of the foil electrode and incident at an angle # equal to Brewster's angle. The devices may be mounted in wave guides or between coaxial conductors, Figs. 2 and 3 (not shown). A curve provided in the foil electrode gives some flexibility. The Specification states that silicon and A<SP>III</SP>B<SP>V</SP> compounds may also be used. The detector may use more than one semiconductor in its construction. For 7000 Š radiation from a ruby laser a high resistivity gallium arsenide layer may be provided on a gallium phosphide substrate, the alloy bonded element being of cadmium. For 1À153 Á (helium/neon laser) an epitaxial layer of germanium on gallium arsenide is suitable. Devices may be constructed with the conductivity types transposed.

[Class 17 (ii)] A welt strip is cut to produce a two-unit welt which is in some cases wider than that usually produced from a given width blank. A slanting cut 23, a horizontal lateral cut 24 adjacent to the grain surface, and a short cut through the grain surface produces two units 25, 26, Fig. 5. The unit 26 is placed below and is moulded and cemented to the unit 25 with the grain lip 27 cemented to the edge, as. shown in Fig. 6, to produce a welt strip having a receding welt shoulder with an inseam flange below it. In modifications, the angles of the cuts are varied to produce different welt shapes but the angle between the cuts 23, 24 is always obtuse. In some cases, Fig. 8, one unit is inverted before moulding and cemented at its flat flesh side to the upper unit so as to form an elevated inseam flange 34, particularly advantageous for shoes with receding toes, which may be trimmed flush without severing the inseam stitch which passes through the crease 36 at the bottom of the receding shoulder. Specification 308,930, [Class 17 (ii)], is referred to.

Abstract: 1382312 Digital transmission; synchronizing INTERNATIONAL STANDARD ELECTRIC CORP 11 May 1972 [21 May 1971] 22127/72 Headings H4P and H3A A synchronizing arrangement has means at the output of a shift register receiving data for extracting timing signals which are compared with a reference clock, the difference controlling register shifting circuitry to bring the received data into a determined phase relation. Incoming diphase signals enter a multistage shift register I where they are shifted by pulses from a controlled oscillator 2 of higher frequency than that of the initial diphase clock frequency. Timing data is extracted by a series arrangement of a sawtooth generator 3 and phase lock oscillator 4. Extracted timing signals are compared at 5 output from which is low pass filtered at 6 and which controls the frequency of oscillator 2. The delay introduced by shift register 1 is sufficient to bring incoming signals into synchronism with the reference clock.  The arrangement described so far will follow slowly changing phase jitter hence to remove rapid jitter signals are passed through gated register 7, also controlled by the reference clock, which strobes signals about the centre of each pulse, i.e. remote from leading and trailing edges.
