Title: Transistor production

Filed: 1963-02-18
Abstract: 1,028,424. Semi-conductor devices. INTERMETALL GESELLSCHAFT FUR METALLURGIE UND ELEKTRONIK. Feb. 18, 1963 [Feb. 16, 1962], No. 6535/63. Heading H1K. A process for the production of mesa or planar transistors comprises forming base and emitter electrodes 3, 4 on a surface of a body of semi-conductor material, covering the surface apart from the electrodes by an insulating layer 5, vapour depositing conducting strips 9, 8 on to the layer so as to contact the electrodes and thereafter detaching the strips from the layer. In the example described a silica layer is formed on a surface of a Si or Ge body 1 and Ag (Au or Cu) strips 8, 9 are then deposited through a mask on to the layer so as to touch the emitter and base electrodes 4, 3. The device is immersed in hydrogen peroxide whereby the strips are detached from the layer and provide rigid projections 8a, 9a to which connecting leads can be soldered. If strips of W, Mo, or Pt are deposited then the electrodes should be masked and the device immersed in an H.F. acid bath whereby the layer and some of the semiconductor body below the strips is removed (Fig. 3, not shown). The electrodes may be formed at the same time as the connecting strips by incorporating suitable doping impurities with the vapour during the deposition process. It is stated that the above process may be applied to a mass production process in which a plurality of transistors are formed from a single slice of semi-conductor.

Title: Diazo type photosensitive sheet developing devices
IPC: G03D13/00
Filed: 1972-02-15
Abstract: 1385373 Developing apparatus RICOH KK 15 Feb 1972 [15 Feb 1971 16 July 1971]  6873/72 Heading G2X A developing device for use with powder developing agent comprises a vessel 7 for the powdered developer, a supply means 14 for metering the powder on to a photo-sensitive sheet in  response to passage of the sheet beneath the vessel and conveying and pressing means 1, 6 for conveying the sheet away from the vessel 7 and pressing the powder into contact with the surface of the sheet to effect development. The device is of particular utility in developing diazo type sheets using a developer consisting of a powdered silica or glass beads moist with organic amine developing liquid. As shown a photo-sensitive sheet advanced on to plate 15 trips micro-switch 16 causing rotation of brush roller 14 to distribute developer on the sheet. The sheet is then advanced by belt 6 and compressed between the belt and the surface of cylinder 1. Heating means 18 may be provided within the cylinder. The discharged sheet is stripped from the cylinder by stripper plates 22 and passed between roller 19 and brush roller 20 which removes surplus developer and returns it to the vessel. A gilater 12 may be provided within the hopper. Brush roller 14 may be replaced by a slatted plate with an oscillating cover-plate which opens the slots to release developer from the vessel Fig. 2, (not shown). In a further embodiment Fig. 3, the opening 121a in the developer vessel 121 is sufficiently close to the photo-sensitive sheet supporting plate 106 for developer powder discharged from the opening to block the passage of further powder until a sheet is fed between the opening and the plate. A continuously rotating metering roller 227, Fig. 4, may be provided between the vessel and the sheet supporting plate 206. When no sheet is present beneath the vessel, accumulation of powder on the plate blocks the orifice 226a.

Title: Improvements in or relating to controllers for electric circuits
IPC: G05G9/047
Filed: 1956-03-06
Abstract: 806,037. Controllers. OFFICINE MECCANICHE RIUNITE S.p.A. March 6, 1956 [May 9, 1955], No. 6960/56. Class 38 (3). A drum controller for hoists and the like is keyed to a shaft 20 and is actuated through bevel gearing 18, 19, from a shaft 21 which is, in turn, coupled to a shaft 22 by means of spur wheels 23. A slotted sector 24 is keyed to the shaft 22, the slot being traversed by the shank of an operating handle 27 which is pivoted on spindle 28 in fork 29. The shaft 31 of another control drum is coupled through a chain drive 30, 32, 33, to a spindle 34 in the fork 29. The arrangement is such that movement of the handle 27 in one plane actuates only the shaft 22 and hence the upper drum, whilst movement in a plane at right angles to the first actuates only the chain drive and therefore the lower drum. A combination of these two movements of the handle provides simultaneous actuation of both control drums, when the handle performs a circular movement, for example. Release of the handle allows it to be returned to its neutral position. Spring-operated switches may be accommodated within the handle. The control gear is enclosed by a housing 14 having a side extension 16. In one arrangement, two similar housings are provided around the sides and back of a seat mounted on a circular hollow pedestal through which the leads to the control drums are passed, Figs. 1, 2 (not shown). The seat is adapted for limited circular movement with a foot-operated brake to hold it in a desired position. A circular foot-rail is provided for the operator. In another arrangement, the two casings are separately mounted upon columns 37 with a space for the operator to stand between them, Figs. 3, 4 (not shown). As shown, adjustment of the position of the casing is provided by a screw 41 in a mounting bracket 40 and engaging a slot 42 in the casing.

Abstract: 842,342. Screwing-up wire-coil inserts. HELI-COIL CORPORATION. March 2, 1959 [Jan. 2, 1959], No. 7087/57. Class 83 (3). A tool for inserting wirecoil screw-thread inserts comprises a casing 10 having a screwed spindle 18, the end 20 of which slides in a sleeve 13 which is rotated in a slide 23 by a spindle R from a powersource S. A non-rotating split-nut 56, 56<SP>1</SP>, releasably engages the spindle 18 and feeds it axially, thus causing the spindle end 19 to enter an insert C and engage a tang T thereon, thereby forcing the insert through a ring 42 and into an internally - screwed workpiece B. In operation, an insert C is placed on the ring 42, which engages the work B when pressure is exerted on the tool. The foot 37 and the sleeves 33, 30, secured thereon move axially inwards until a pin 52, secured to sleeve 30 and sliding in a slot 53 in a member 46, screwed in the casing 10 at 47, abuts the inner end of the slot, the nut 56, 56<SP>1</SP> being thereby closed on to the spindle 18 by fingers 61, 61<SP>1</SP> on the sleeve 30. The sleeve 13 is rotated, and rotates the spindle 18 through a pin 21 on the spindle-engaging slots 16 in the sleeve, thus feeding the spindle 18 until the slot 26 engages the tang T on the insert C and screws it through the ring 42 into the work B. The ring 42 is bevelled to contract the insert to a diameter less than that of the hole in the work.
