Patent FI-19991929-A (FI)
Inventor: ANNAMAA PETTERI
IPC: H01Q5/00
Filed: 1999-09-10
Abstract: The invention relates to a planar antenna structure in small-sized radio apparatus. A layer of dielectric material (230), the dielectric constant of which is relatively high, is arranged outwards of the plane of the outer surface of the radiating element (210) of a planar inverted F antenna, or PIFA (200). The layer is located so as to cover at least the areas in which the electric field is the strongest when the antenna resonates. In the case of a dual-band antenna the slot (215) in the radiating element is made advantageously so wide that the effect of the coupling between the branches (A1, A2) of the element is small. An antenna according to the invention can be made smaller in size and at least as good in its electrical characteristics as a corresponding prior-art antenna. Alternatively, the electrical characteristics of the antenna can be substantially improved without making the size of the antenna bigger.  <IMAGE>

A buckle includes a female strap connector 2 and a male strap connector 7, Fig. 2, each having means for receiving a strap; projecting means in the form of a prong or prongs 6 on the male connector insertable into a channel or channels 4 in the female connector; releasable retaining means comprising a rocking element journalled in the female connector transversely of the channel or channels, the rocking element taking the form of a shaft 8, Fig. 5, having a cut-away portion or portions 12 corresponding to said prong or prongs whereby movement of the rocking element to a first position is effective to align said cut-away portion or portions with the channel or channels and thereby to permit the prong or prongs to be inserted in said channel or channels and movement of said rocking element to a second position is effective to displace the cut-away portion or portions from the channel or channels so that the shaft projects into the channel or channels and is engageable in a notch or notches 11 provided in said prong or prongs thereby to retain the prong or prongs in the channel or channels and handle means for moving the rocking element from said first position to said second position and vice versa. In one embodiment the handle means comprises a yoke lever provided with a handle bar 19, Fig. 5, when the yoke lever is released it rotates clockwise under spring action to the position of Fig. 5 in which the shaft 8 retains the prongs and is held against accidental rocking to its releasing position by a spring loaded flap 42 with flanges 48. So that the prongs may be inserted without releasing the yoke lever relative rotation of shaft 8 and the yoke lever is permitted in one direction by a lost motion connection, Fig. 10, not shown. Alternatively the yoke lever is rigidly attached to the shaft, Fig. 11, not shown. Correct alignment of the male and female connections is assured by having the prongs 6 of different widths, and providing projections 17, Fig. 2 on the male member which enter recesses 14 on the female member. In a second embodiment Fig. 12, dogs 64 on the yoke lever 53 enter recesses in the female member to prevent accidental rotation of the shaft 8. To release the prongs 6 a spring loaded cross head 52 is depressed which pivots the dogs 64 about pins 66 under the action of a pin and slot connection 69, 71 so that they are withdrawn from the female member and allow swinging of the yoke lever 53.

Abstract: 1,228,589. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MFRS. Ltd. 2 April, 1968 [9 May, 1967], No. 21414/67. Heading H1K. A planar semi-conductor device comprising a  first zone of one conductivity type formed as an inclusion in one face of a semi-conductor body or zone of the opposite type and a second zone of said opposite type formed as an inclusion in the first zone is made by diffusion. The second zone is formed by diffusion through a hole in a first masking layer and the first by diffusion through a larger hole, embracing the first hole or its site, formed in a second insulating layer. The material of the first masking layer is pervious to the impurity diffused to form the first zone. In making a bipolar transistor an epitaxially formed N surface of an N+N silicon wafer is first treated in wet oxygen to form an oxide coating. Silicon nitride is deposited over this by reaction of ammonia and a silane or halosilane, and is in turn coated with silica by pyrolysis of tetraethoxysilane. The base diffusion hole is formed in the nitride by etching with hot phosphoric acid through an aperture formed in the silica overlayer by photoresist and etching steps, using a hydrofluoric acidammonium fluoride mix. Then an emitter diffusion hole is formed in the exposed oxide by photoresist and etching steps. The wafer is next heated in a sealed ampoule containing galliumdoped silicon, the gallium diffusing through the oxide to form the base zone. The emitter is formed by reheating in a flowing mixture of phosphorus oxychloride, oxygen and nitrogen. In an alternative process the base and emitter are formed by simultaneous diffusion of gallium and arsenic, the gallium penetrating less deeply beneath the emitter zone due to the inhibiting, effect of the arsenic doping therein. The dopants may be derived from arsenic and gallium doped silicon powder in a sealed tube or from oxides of arsenic and gallium in an open tube process. Alternatively arsenic glass is predeposited by passing an arsenic halide, a siloxane and oxygen over the wafer and the wafer then heated in a sealed tube containing gallium-doped silicon. Another possibility is to form the emitter first by diffusion of arsenic and-then the base by diffusion of gallium. It is also possible to form the emitter diffusion hole after the base diffusion or the nitride masking after the emitter diffusion. In all cases electrodes are afterwards formed by etching away any glassy deposits in the emitter diffusion hole, etching an annular aperture through the oxide over the base zone, depositing aluminium overall, and then back-etching to form separate electrodes. JUGFETS are made in the same way save that the annular base electrode is replaced by spaced source and drain electrodes, the "emitter" electrode in this case functioning as gate. In a preferred device there are a plurality of parallel emitter regions interconnected by an electrode which is interdigitated with the base electrode (Fig. 19, not shown).

Abstract: 1,232,575. Making stators; welding by fusion. MATHER & PLATT Ltd. 21 June, 1968 [13 April, 1967], No. 16962/67. Headings B3A and B3R. A method of making core -packs for stators of dynamo-electric machines comprises locating a plurality of laminations at their outside edges to form a core stack, thereafter compressing the core stack and axially uniting the laminations to form a core pack. The laminations are placed over a shaft 16 of a core building apparatus and a key tab of each lamination engages in a keyway in one of four locating arms 15, the other arms locating the laminations diametrically. When the stack is of the required length, drifts are passed through slots in the laminations and through a core pressing plate 18, and the stack is then inspected for slot and bore linearity. A further core pressing plate 19, spherical washers 24, 25, and a press ring 26 are placed on the end of the shaft and a spider ring 30 is placed on the ends of the arms 15. The shaft 16 is then withdrawn hydraulically to compress the laminations and they are welded by three welding heads 21 of an automatically indexed rotational welding machine. Copper pads 20 on the plates 18, 19, allow high frequency arcs to be struck and permit stabilization of the arcs prior to the welding heads 21 traversing the laminations. Alternatively the circumferences of the plates 18, 19 are covered with copper. When the welding is completed the ring 30, plate 19, washers 24, 25 and press ring 26 are removed and the end of the shaft 16 retracted through the plate 18. A press plate (23) is fitted into an arcuate housing 22 on the plate 18. The shaft 16 is then advanced so that it abuts the plate (23) and presses the core pack out of the jig apparatus, Fig. 2 (not shown). The core pack is placed on a rotating turret head adjacent the welding machine, the head offering two support arms marrying radially with the two bottom arms 15, and from which it can be removed for winding.
