Patent GB-2067337-A (GB)
Title: Tape recorder
IPC: G11B15/04
Filed: 1980-01-08
Abstract: Movement of any one of a playback 16, rewind 17 or fast forward 18 (Figure 2) selecting member to an operative position moves a power switch operating member 39 to the left and thereby moves an erroneous-recording preventing member 61 into a position preventing operation of a recording selector 15. Pushing in recording selector 15 from the stop position simultaneously pushes in playback selector 16 via an L-shaped part 151 of selector 15. If rewind selector 17 is pushed in during recording, it shifts locking plate 38 sufficiently leftwards to release recording selector 15 but not playback selector 16, and plate 38 will not then lock rewind selector 17 so that on release of the latter playback is assumed, thus giving the quick review mode. Fast forward selector 18 can similarly be used to give the cue mode. Member 61 is integrally formed of plastics with elastic 611 and inelastic 612 prongs between which is located a projection 63 on member 39. On release of recording member 15 by pressing member 17 or 18, a projection 65 on member 15 engages a cam surface 642 on member 61 to pivot the latter anticlockwise out of the path of member 15, the elastic prong 611 thereafter returning member 61 to the position in which a surface 641 (Figure 5) thereon blocks movement of the recording member 15 to its operative position. <IMAGE>

Title: Solid state switching system for coupling a d-c power supply to a load
IPC: H02M3/155
Filed: 1980-09-02
Abstract: A d-c power supply is connected to a load via a power transistor triggered to its saturation condition by periodically recurring pulses having a time separation between successive pulses less than the transistor's storage time. Due to the storage time, the transistor (10) remains saturated in the absence of base drive current between pulses and maintains a continuous coupling of the d-c power supply to the load. With intermittent base current, substantial power is saved not only in the base drive circuit but also in the transistor itself. <IMAGE>

Patent GB-2059944-A (GB)
Title: Fabrication method of optical fiber preforms
IPC: C03B37/014
Filed: 1980-10-02
Abstract: In fabricating an optical fiber preform, a synthesizing torch (4) is inclined by 10 DEG  to 60 DEG  with respect to the rotation axis of a seed rod (2). Moving the rod while rotating it, a glass raw material gas and a flame forming gas are blown out individually from the torch to synthesize glass particles which are deposited onto one end of the rod, so that a cylindrical porous preform is grown in the direction of the rotation axis of the rod. Then the porous preform is heated at a high temperature to vitrify the porous preform into a transparent optical fibre preform. At least one exhaust port (9) is disposed with a distance of 1 mm to 50 mm from the periphery of the porous preform and in the vicinity of the growing surface of the porous preform. In fabricating the porous preform the outer diameter fluctuation is small, and the preform is formed stably without formation of crack on the periphery of the preform. The growing speed is improved easily. The synthesizing torch, e.g. Figure 15a (61) for core is so arranged to produce a glass particle stream deviated from the center area of flame stream. The diameter of a core may be narrowed to 10 mm or less, cladding-to-core-diameter ratio may be increased to be three or more. The mass-production of long-length and low-loss single-mode optical fibers is possible by VAD method. <IMAGE>
