Abstract: 1277290 Cine cameras CANON K K 28 Aug 1969 [28 Aug 1968 30 Aug 1968] 42829/69 Heading G2E In a cine camera, the film winding shaft, bearing a driving pawl for engagement with the film core 5 of a magazine, is carried on bracket 8<SP>1</SP> of a lever 8 which is spring-loaded for rotation about pins 7 such that insertion or withdrawal of a magazine 2 causes lever 8 with the winding shaft to be moved outwardly from the magazine chamber, this outward movement permitting the setting of a spring-loaded film-footage counter 15 to zero. Driven gear 14 drives a gear 9 carried on bracket 8<SP>1</SP> and spring-clutched to the winding shaft, and also drives a gear 18 having a spiral cam groove 19 engaged by follower pin 20 on counter 15. Pin 20 is disengaged by the outward movement of lever 8 in response to opening of door 3 to release a latch mechanism 12, 13. In another embodiment, the worm gear drive to a rotating disc footage indicator is disengaged by the camming action of a magazine during insertion into the camera. The pivoting lever bearing the winding shaft is cammed away from the magazine film core-until insertion is completed. A multi-start spiral 19 may be used.

Apparatus for producing longitudinal welded seams in a thermoplastic tube in a tubular bagwrapping machine of the type in which a tube of thermoplastic wrapping material 3 is formed from at least one web of wrapping material by welding the longitudinal edges of said web or webs together, said tube then being formed into filled packages by the formation of transverse welded seams and filling with the goods to be packaged, is characterized in that the superimposed longitudinal edges of the wrapping material 3 pass between at least one pair of rollers 1, 2 resiliently urged together and a heater 11, 17 is situated in close proximity to the rollers 1, 2 so that the heat of the heater is transmitted to the rollers 1, 2 by radiation and convection. As shown, the material 3 passes between three pairs of rollers 1, 2 secured on shafts 6, 16 mounted in parts 5, 15 of a housing. One of the rollers 1 is driven by a device (not shown) and the rollers 1, 2 are synchronously rotated by meshing tooth wheels 10, 18 mounted on the shafts 6, 16.

The post 5 is preferably provided at its lower end with a U-shaped bracket 13, one arm of which 15 engages with the arm 32 of latch black 26 mounted on a rectangular plate 24 which forms the base. The arm 15 is provided with a recess 16 which engages member 33 which extends through a recess in the latch block and is held in position by blade spring 29. The post may also be provided with a pivot block 17 which rests on a bearing plate 34 and with a bracket 38 having an inclined lower surface 39 situated between the pivot member 17 and the bottom of the post.

Title: Field-effect device with insulated gate
IPC: H01J37/317

Abstract: 1,139,623. Semi-conductor devices. HUGHES AIRCRAFT CO. 29 Sept., 1967 [27 Oct., 1966], No. 44455/67. Heading H1K. A method of making an insulated gate field effect device comprises the steps of (a) forming an insulated gate electrode on a portion of the surface of a semi-conductor body, and (b) causing ions of a conductivity-type-determining impurity to impinge on the surface so that source and drain regions of like type are established in the body adjacent the channel region under the electrode. In a preferred embodiment a layer 4 of silicon oxide or nitride is formed on the surface of a silicon body 2, an opening is etched in the layer, a thin layer 6 also of silicon oxide or nitride is formed in the opening, and an aluminium gate electrode 8 is vapour deposited on the layer 6. A beam of ions of a suitable impurity, e.g. boron or indium, is then directed on to the surface and penetrates into the silicon body, except where the surface is shielded by the layer 4 and electrode 8, to form source and drain regions 10 and 12. Finally, portions of the layer 6 are removed by etching and aluminium is deposited to form source and drain contacts 14, 16. In a modification the layer 6 is removed from the parts of the surface not covered by the electrode 8 before the ionic bombardment. The thickness of the layer 4 depends on the desired depth of the regions 10 and 12 and the ion beam energy; for a low energy beam and a penetration depth of 0À2-0À6Á the layer 4 should be in the range 0À1-0À6Á thick. If a high energy (100kv. or above) beam is used the layer should be about 1Á thick. The layer 6 may be 0À1-0À2Á thick, and the regions may be straight or concentric in shape. In an alternative embodiment the layer 4 is omitted so that the implanted regions extend to the edges of the body; the layer 6 may then be formed over the whole surface. An apparatus is described (Fig. 6, not shown) for vaporizing and ionizing the impurity.
