Title: Object inspection system
IPC: G06V10/10
Filed: 1979-04-10
Abstract: In an inspection system in which a reference object is photoelectrically scanned and the scan signal stored for comparison with the signal produced when a sample object is scanned, a calibration body is included in both reference and sample scans and any difference between the parts of the reference signal and sample signal corresponding to the calibration body is used to correct at least the part of the sample signal corresponding to the sample object.

Title: Optical System for Reproducing Information
IPC: G11B7/135
Filed: 1980-06-20
Abstract: An optical system for reproducing information has a semiconductor laser 21, forming a light source, which emits a beam L of light towards an optical disk (not shown). The beam L passes through an opening 24 in a holder 25, through a beam splitter 22, and is then incident on a plano-convex lens 23, with its planar surface nearest to the laser 21 which collimates the beam L. The beam L is then focused onto the disk and reflected. The reflected beam, which varies in intensity in dependence upon the information recorded on the disk, is reflected by a joint plane in the beam splitter 22 and received by a photodetector (not shown). With this arrangement, the elliptical beam from the laser 21 is rendered circular by opening 24 and is focused as a circular spot on the disc and aberrations produced by the system are less significant. To increase the optical efficiency, the lens 23 and the beam splitter 22 may be combined in a one-piece structure (Figures 4, 5). <IMAGE>

Title: Cathode-diaphragm unit for chloralkali electrolytic cells
IPC: C25B9/19
Filed: 1981-06-01
Abstract: A cathode-diaphragm unit comprises:     a. a cathode; and b. a deposited diaphragm comprising a self-adherent, entangled fibrous mass of non-woven, unoriented fibers, conforming to, spaced from the non- adherent to the cathode.   The unit can be prepared by depositing fibers on the cathode to form an entangled fibrous web, and depositing protective material atop the cathode and thereafter depositing the diaphragm and forming the fibrous entanglement. Since the surface of the cathode facing the diaphragm is essentially free of adherent diaphragm material hydrogen is collected between the diaphragm and cathode and the cell voltage is lower than that of prior art cells in which the diaphragm is applied directly to the cathode. Moreover removal of the diaphragm does not result in removal of catalyst from the cathode surface.

Title: Methods manufacturing field effect transistors
IPC: H01L29/20
Filed: 1981-12-01
Abstract: The gate insulator of an InP field effect transistor comprises aluminium oxide formed by pyrolytic decomposition of aluminium alkoxide. The insulating layer is obtained by heating the substrate 1 to 350 DEG  to 450 DEG C in a chamber 11 held at a pressure below atmospheric pressure e.g. 1 Torr. Aluminium alkoxide in a nitrogen gas carrier is then caused to impinge on the substrate, where it decomposes. The remainder of the apparatus is maintained below the reaction temperature, e.g. maintained within the range 100 to 300 DEG C. Aluminium alkoxide is formed by passing nitrogen 18, 20 over liquid aluminium isopropoxide 14 heated to around 124 DEG C. <IMAGE>
