Title: A Method of Manufacturing a Semiconductor Device and a Semiconductor Device Obtained Thereby
IPC: H01L23/29
Filed: 1968-05-01
Abstract: 1,190,893. Semi-conductor devices. HITACHI Ltd. 1 May, 1968 [4 May, 1967], No. 20694/68. Heading H1K. A method of etching an insulating passivating layer 13 on the surface of a semi-conductor device without the occurence of excessive lateral etching of a glass layer 14, provided on the layer 13 to prevent channel effect, comprises covering the surface of the glass layer where required with a film 15 of silicon nitride before etching. This layer of silicon nitride is used as a mask during the etching process for which suitable etchants are those consisting mainly of hydrofluoric acid such as HF-HNO 3  or HF-NH 4 F. The required pattern of the silicon nitride layer is obtained by using a photo-resist film 17 on a silicon dioxide film 16, both of which are removed by being etched with boiling phosphoric acid. The glass consists principally of silicon dioxide combined with at least one of an oxide of phosphorus, boron or lead, and the insulating passivating layer is silicon dioxide.

Title: Improvements in and relating to refrigeration defrost control
IPC: F25D21/02
Filed: 1964-05-20
Abstract: 1,023,328. Defrosting. CONTROLS COMPANY OF AMERICA. May 20, 1964 [July 3, 1963], No. 20707/64. Heading F4H. A defrost control comprises a frost-sensing member movable cyclically towards and away from a surface on which frost accumulates, means responsive to the detection of a predetermined accumulation of frost to change the temperature within a housing and means responsive to said change in temperature to initiate a defrosting cycle. As shown, a heater 12, a first bimetallic element 14 and a second bimetallic element 20 are mounted in a housing 10, element 14 being connected to a bracket 17 which carries a sensing finger 18 at its face end and a plunger 24 intermediate its ends. The plunger is arranged to actuate a snap-action switch 28 controlling the heater 12 and the arrangement is such that when the heater is energized the element 14 moves the finger 18 away from an evaporator tube 44 until the plunger permits the switch to open and de-energize the heater. As element 14 cools it moves the finger towards tube 44 and if the post thereon is of less than a predetermined thickness the movement continues until switch 28 is again closed. If the movement is previously arrested by the presence of frost, the temperature in the housing continues to fall and the second element 20 actuates a defrost switch 38 to initiate defrosting which is terminated when the ambient temperature rises sufficiently to cause element 20 to open switch 38. The latter may be included in a control circuit so that when closed it de-energizes the compressor, an evaporator fan and heater 12 and energizes a defrost heater and a defrost-water drain heater (Figs. 2 and 3, not shown). The circuit may also include a thermally responsive switch which either de-energizes the defrost heater before the drain heater is de-energized by opening of switch 38 or re-energizes the compressor and de-energizes the defrost heater prior to switch 38 opening to de-energize the drain heater. Alternatively, closing of switch 38 energizes a drain heater and the solenoid of a hot-gas defrosting valve, the solenoid being de-energized before the drain heater by a thermallyresponsive switch (Fig. 4, not shown).

Filed: 1958-06-30
Abstract: 835,188. Control of several motors. TELECOMMUNICATIONS S.A., DE. June 30, 1958 [July 12, 1957], No. 20879/58. Class 38 (3). [Also in Group XXXVI] In a machine for preparing a random-twisted pair for incorporation in a telecommunications cable (see Group XXXVI), the twisting head 1 (Fig. 1) carrying supply reels 4 1 , 4 2  is driven by a constant-speed motor 3 and the take-up winch and drum 6, 7 are driven by a variablespeed motor 11. The speed of motor 11, and therefore the ratio of the speeds of the motors 3, 11 is varied by a control device 15 fed at 16 with signals obtained from a random signal source 17 via a filter 18 and sampled at intervals by a device 19. Figs. 3 and 4 show the layout of the control device 15. Voltages from tachometer generators 14, 13 on the motor shafts are fed to a variable potentiometer 21 and a fixed potentiometer 22 respectively. The outputs from the two potentiometers are combined in opposition and the error signal fed to two parallel-connected amplifiers 24, 25 and a power amplifier 26. The amplifier 26 is connected to the rotor of motor 11. Thus the speeds of the motors 3, 11 are kept at a ratio depending on the position of the wiper arm of potentiometer 21 and this wiper arm is positioned according to the random signal fed in at 16 by a permanent magnet D.C. motor 31. The signal at 16 is fed to the centre point of a potentiometer 32 (whose wiper arm is mechanically connected to the wiper arm of potentiometer 21), the potentiometer being connected to a D.C. source 33. The resultant voltage from the wiper arm is fed to an amplifier 34 whose output is connected to the armature of the motor 31.

Title: Apparatus for detecting the presence of foreign bodies in bottles
IPC: G01N33/00
Filed: 1977-05-19
Abstract: A beam splitter (16) with a semi-reflecting interface is arranged in the beam path between the bottle bottom, which is illuminated by a light source (4), and the two photoelectronic scanning devices (10, 11 and 17). The beam splitter (16) transmits an image of the bottle bottom to each scanning device (10, 11 and 17). The first scanning device (10, 11) inspects at least the edge region of the bottle bottom and the second scanning device (17) inspects at least the central region of the bottle bottom, the inspection regions of the two scanning devices partially overlapping each another. As a result of this, the sensitivity of the apparatus is completely independent of the position of the foreign body on the bottle bottom and a high degree of reliability is achieved in the detection of foreign bodies, even in drinks bottles which are in continuous motion. <IMAGE>

Filed: 1974-05-14
Abstract: 1446123 Actinide gel particles INTERFUEL BV 14 May 1974 [18 May 1973] 21264/74 Heading C1A Gel particles of actinides are prepared by contacting a jet of an aqueous sol. containing a compound of an actinide metal and optionally carbon, with a stream of water-imiscible gelling liquid, where at the point of contact both jet and stream are in a state of laminar flow, the linear velocity of the gelling liquid being lower than that of the stream of sol., the jet of sol. being in a state of free flow before coming into contact with the stream of gelling liquid. The stream of gelling liquid may be in a state of free flow at the point of coming into content with the jet of sol. The jet of sol. and stream of gelling liquid may come into contact at a right angle. A plurality of jets of sol. may come into contact with a broad stream of gelling liquid. The stream of gelling liquid may have a viscosity of at least 10 centistokes under operating conditions. The gelling liquid may exert its gelling action by the presence, e.g. of ammonia donas, e.g. hexamethylene tetramine and urea. The actinide gel particles obtained may be converted to globules of hydroxides, oxides and/or carbides by washing, drying, calcination, sintering and/or reducing. A tube containing the globules may be used as a fuel element for a nuclear reactor. The process provides globules with an improved uniformity of size.
