Title: Electron beam/semiconductor devices
IPC: H03F5/00
Filed: 1975-08-27
Abstract: 1493601 Cathode-ray tubes DEFENCE SECRETARY OF STATE FOR 27 Aug 1975 [5 June 1974] 25043/74 Heading H1D In an electron beam/semiconductor device one or more electron beams are scanned over the surface of a reverse-biased distributed diode arranged as a length of transmission line. A beam at least equal to the width of the diode may scan it longitudinally (Fig. 3, not shown), preferably at a speed equal to the speed of propagation of the injected electron-hole pulse, the diode being connected to a matched load equal to the impedance of the line. The output pulse at the opposite end of the diode, which arises from the backward wave, is of the same energy as the forward pulse, but of lower amplitude and longer duration. A c.w. output may be produced by employing a sequence of electron beams following one after the other down the line. Alternatively, lateral scanning (Fig. 4, not shown) may be employed, in which the beam illuminates the whole length of the line simultaneously, equal pulses being obtained at each end of the line, unless a reflective termination is employed at one end. In Fig. 5, the diodeformed of an N<SP>+</SP> substrate 54, a depletion region 56 extending either side of a junction 57, and a P-type layer 58, is provided with upper and lower electrodes 50 and 52. The upper electrode 50, upon which the electron beam is incident, is regularly castellated along its length, the thicker portions 60 being opaque to the beam to define an apertured mask, the output being a train of pulses of number equal to the number of apertures in the mask. Repetitive scanning with the same repetition frequency as the pulse repetition rate yields a continuous sequence of pulses. A plurality of such masked diodes 70, Fig. 8, may be formed side-by-side on a single slice of semiconductor and laterally scanned by an electron beam 76, the diodes being connected to respective aerials 74 by lines of different length, as shown, to provide normal beam emission from the aerial array for a given electron beam scanning rate; variation of scanning rate then permits beam steering. Reference is made to the use of anisotropic diodes of the form disclosed in Specification 1,493,602.

Title: Improvements in or relating to the lasting of boots and shoes
IPC: A43D9/00
Filed: 1929-08-21
Abstract: 338,558. United Shoe Machinery Corporation, (Assignees of Fausse, J.). May 13, 1929, [Convention date]. Connecting uppers to insoles and soles. - Relates to methods of lasting wherein temporary binding members hold an upper in position about the end of a shoe which members have contact over a substantial area with the shoe. A binder of this kind, Fig. 7, has a flat portion 18, Fig. 7, for engagement with the marginal portion of the sole or insole perforated at points 22 along its length for the insertion of temporary holding tacks, and an upstanding flange 20 recessed at each perforation. The binder is pressed against the bottom face of the last by the wipers of a lasting machine, and the recesses allow the tacks to be driven beyond the edges of the wipers, the heads of the tacks engaging the edge of the upturned flange to maintain the pressure exerted by the wipers after their retraction. The binder remains in position until the upper has become set or secured in position, e.g. by the setting of a thermo-plastic stiffener or cement previously applied to the surfaces at the margin of the upper, the inwardly extending margin being, thereafter, trimmed. The margin of the upper at the sides of the shoe may be fastened to the sole by metallic fasteners anchored in the sole in bent condition without penetrating right through the sole as described in Specification 294,640. In making a shoe of the kind wherein the sole is secured direct to the inturned margin of the upper, which, therefore, is lasted over parallel to the insole, the margin of the lining and stiffener may be cut away so that the edge of the upper leather may be secured directly to the insole by cement. A lasting machine may be used of the kind having a toe band 16, wipers 14 and a treadle for moving these members heightwise of the shoe for upwipe and for producing a downward pressure of the wipers at the end of their travel. The upper is preliminary shaped, before the cement is applied, by manipulation of the wiping means, which are then retracted. The cement is then applied, and the wipers advanced over at least a portion of the width of the upper margin, lifted and partially retracted. The binder is then in- .serted and the wipers again advanced to force the binder inwardly and press it heightwise of the shoe. Fasteners are then inserted to maintain this pressure, e.g. two tacks at each side of the toe. When the cement has set the tacks are withdrawn and the binder removed. The binder is somewhat yieldable laterally, so that it may be used repeatedly on successive shoes. The margin of the upper beyond the flattened portion is then trimmed off. In the case of a welt shoe, Fig. 9, the wipers engage the binder to bed the upper into the angle between the feather and lip of the insole, this shape being maintained, after the removal of the binder, by the setting of a thermoplastic stiffener.
