Patent GB-1139970-A (GB)
Title: A laser apparatus
IPC: H01S3/101
Filed: 1968-01-05
Abstract: 1,139,970. Lasers. INTERNATIONAL BUSINESS MACHINES CORP. 5 Jan., 1968 [13 Jan., 1967], No. 734/68. Heading H1C. A laser includes an angularly degenerate resonant cavity comprising a first reflecting surface 11 and an electro-optical element 20 presenting a second reflecting surface 21, the refractive index of a selected portion or portions of the element being variable in such a way that stimulated emission occurs from a laser active medium 10 in the cavity along a selected path or paths. Fig. 1, shows a scanner. Element 20 has a dielectric reflecting surface 22 spaced from the conducting reflective surface 21 such that the element defines an etalon normally resonant at the output wavelength of the laser. The element is formed as the face of a cathode ray tube 23 which can be controlled to direct electrons on to a selected portion of surface 22. The resulting local electric field changes the refractive index of a portion of element 20 so that it is no longer resonant near this portion. The corresponding portion of surface 21 then becomes highly reflective and forms a high- Q resonant cavity with its own image in mirror 11. All other possible modes remain in low-Q conditions and are suppressed. The initial resonant condition of element 20 is adjusted by controlling its temperature, or the initial mechanical or electrical stress applied to it. In Fig. 2 two laser cavities have a common electro-optical element 30, which is in this case normally non-resonant so that the cavities are not coupled. Laser A is pumped above its lasing threshold, whereas laser B is just below threshold. When a region of dielectric reflector 35A is selected by an electron beam from 37 or 39 the etalon becomes resonant in this region, and the two cavities are coupled for a mode which resonates in the cavity between mirrors 31A and 31B and through the " window " formed in element 30. Mirror 31B (or 31A) is partially transparent. The provision of two electron guns 37, 39 permits the performance of logic. Since the etalon formed by element has a series of transmission peaks corresponding to different electric field strengths it is possible to open a " window " with an electron beam from one gun (binary 1), to close it again with a second beam (binary 0), and re-open it with a third (binary 1), there being a delay between the placing of a charge on the element and its decay. Instead of using an electron beam the dielectric reflector 22 or 35A may be replaced by a mosaic of conductive and reflective areas, each connected individually to a voltage source.

Title: Improvements in film projection apparatus with two or more synchronously driven gramophone turntables
IPC: G03B31/00
Filed: 1930-01-08
Abstract: 342,492. Gramophones associated with kinematographs. NAAMLOOZE VENNOOTSCHAP HANDELMAATSCHAPPIJ LOETAFOON, The Hague. Jan. 8,1930, No. 758. Convention date, Jan. 8, 1929. [Class 40 (ii).] Relates to film-projection apparatus adapted to work in association with any one of two or more gramophone turntables. In order that the same apparatus may be used with records of different manufacture requiring different rotational speeds, provision is made whereby the ratios between the respective speeds of the different turntables and the speed of the cinematograph driving shaft are different. A cinematograph projector A is driven through a flexible shaft 10 from an electric motor B which also drives a multiple gramophone device C through a flexible shaft 11. The device C comprises three turntables 12, 13, 14 which are driven singly by a shaft 15. The shaft is slidable longitudinally by a lever 16 to make driving connection with one of the three turntables. Each set of gear wheels from the shaft 15 to the respective turntable spindle has a different gear ratio so that the respective speeds of rotation of the turntables are different for the same rotational speed of the shaft 15. Other dispositions of the turntables are illustrated, and the toothed change-speed mechanism may be replaced by friction wheels or driving belts.

Title: Crossed-field amplifier tubes
IPC: H01J25/55
Filed: 1962-01-10
Abstract: 968,904. Magnetron amplifiers. S-F-D. LABORATORIES Inc. Jan. 10, 1962 [Jan. 23, 1961], No. 960/62. Heading H1D. In order to stop the continued operation of a high-frequency crossed-field amplifier tube having a non-re-entrant slow wave circuit and a re-entrant space charge space after it has been turned off, due to self-sustained secondary emission at the surface of a cold secondary emissive cathode, a control potential pulse is applied to the cathode end hats 27, Fig. 1, to distort the carbode-anode potential distribution. The control pulse may be negative or positive. In Fig. 1 the anode structure comprises cavity resonators 16 communicating through apertures 19 with a serpentine non- re-entrant wave circuit 18. In the cathode structure of Fig. 3 control wires 37 extend between the end hats 35 and are positioned beyond the periphery of the cathode 34 or, as shown, within grooves in the periphery of the cathode. In another arrangement the control wires extend circumferentially. In Fig. 7 control electrode discs 51 intervene with cathode discs 52. The separate cathode and/or control sections may be operated at different potentials or different cathode-anode spacings may be used for the different cathode sections, e.g. to secure broad-banding of the tube operation. The control discs 51 need not extend beyond the surface of the cathode discs 52 or the control discs may be serrated by radial slots or by the provision of spaced-apart projecting hairpins or wires in order to avoid shorting out of the R.F. fields.

Abstract: PURPOSE:To prevent an attracting capacity from deteriorating coused by the deposition of dust on an attracting surface and the surface roughness of an object to be attracted in the object to be attracted with an electrostatic force in the application of DC current between electrodes by forming an elastic layer on the surface of an electrostatic chuck body. CONSTITUTION:An electrostatic chuck has an electrostatic chuck body 20 having two metallic electrods 2a, 2b incorporated in a dielectric 1. A dielectric polalization phenomenon is generated in the dielectric 1 by applying DC voltage between two electrodes 2a, 2b from a DC power source 3. When under such a condition an object 4 to be attracted such as a conductor and semiconductor is mounted on the electrostatic chuck body 20, the object 4 to be attracted is attracted fixedly by an electrostatic force. Then, the dielectric 1 is composed of a non-elastic dielectric layer 1a and elestic layer 1b and the electrodes 2a, 2b are embedded in the non-elastic dielectic layer 1a side. Thus, even if dust is deposited on the object 4 to be attracted, the dust is buried in the elastic layer 1b so that the object 4 can be fixedly surely attracted.
