Title: Circuit packages and methods for making circuits packages
IPC: H01L23/433
Filed: 1977-08-05
Abstract: A circuit package exhibiting an excellent heat transfer path from a semiconductor chip or other heat-generating device to the heat-sink can or cover of the package. A heat-conducting pad is metallurgically bonded to either said cover or a surface of said device; the pad is also separably attached, but metallurgically unbonded, to the other. In one preferred embodiment, a readily deformable metal or alloy, such as indium, is metallurgically bonded to a limited central region of the heat sink cover. The deformable metal is separably attached to a major surface of the chip so that there is no stress between the chip or its joints and the solder during the electrical operation of the chip when it generates heat. The preferred method of fabrication involves the mechanical deformation of a mass of solder against the back side of the chip, after the solder has been metallurgically bonded to heat sink. The process may be accomplished either at high or low temperatures, depending upon the solder composition and the relative strength of the leads which join the chip to conductive lands on its supportive substrate.

Title: Improved releasable stop device for presses
IPC: B30B11/04
Filed: 1963-08-22
Abstract: 1,024,401. Releasable stop devices. CINCINNATI SHAPER CO. Aug. 22, 1963 [Sept. 6, 1962], No. 33345/63. Heading B5A. In a compression moulding machine for moulding powdered materials, a stop mechanism supporting one of the press members is released by a mechanism which is triggered independently of the pressure exerted by the other press member. In a preferred embodiment a platen 25 carrying a mould part is supported by a stop-rod 23 the lower surface 24 of which co-operates with a wedge member 11, slidable to an inoperative position along guide 10 against the action of compressed gas in cylinder 22. The wedge member is retained in the operative position shown in Fig. 1 by a latch member 16 which co-operate with suitable recesses 17a in the guide 10 and which is released by finger 19 of a trigger lever 14 pivoted in a recess 13 in the wedge member. At a predetermined stage in the compression moulding operation an ejected rod 30, carried by the movable platen, bears down upon a spring- biased trigger rod 26, 28 which depresses the trigger lever about pivot 15 to release the latch member as in Fig. 3. Continued pressure of the ejector rod upon the stop-rod 23 forces the wedge member to the right, as viewed in Fig. 3, into an inoperative position. The platen 25 is thus free to move downwards thus facilitating the ejection and subsequent removal of the finished article from the mould. The wedge member returns to the operative position upon release of the pressure by means of the compressed gas in cylinder 22.

Abstract: 1447881 Image recording coating TEIJIN Ltd 12 July 1973 [12 July 1972 17 July 1972 4 Sept 1972 25 Dec 1972 27 Dec 1972 4 May 1973] 33385/73 Heading B2E [Also in Divisions D2 and H4] In a facsimile receiver a direct image is reproduced on an electrically conductive coating formed on a base material by oxidising and/or reducing the coating which is transparent in a highly oxidised state and non-transparent in a state reduced to a greater degree than the highly oxidised state. The coating comprises solely an indium oxide, a tin oxide, a titanium oxide or a zirconium oxide or a mixture of two or more of these oxides. The coating of the base material may be effected by vacuum evaporation or sputtering of the oxide; or by formation of a layer of the metal by vacuum evaporation, supttering, plasma spraying, vapour-phase plating, chemical plating or electroplating followed by oxidation of the metal coating; or by a method involving the thermal decomposition of the metal chloride. The indium oxide coating preferably comprises a low oxide of indium i.e. In x O y  where O<y/x<1.5, and in a preferred embodiment the coating contains at least 80% by weight of a low oxide of indium and not more than 20% by weight of a low oxide of tin (Sn a O b  where O < b/a <2). Recording is effected by bringing an electrode into direct contact with the coating, by scanning the coating with a pulsed laser beam, or by bringing an electrode into contact with the coating through an electrolytic layer e.g. a transparent polymeric electrolyte or an electrolytic solution thereby to electrolytically oxidise the coating. The electrolytic layer may alternatively comprise water, aqueous solutions of inorganic acids, aqueous solutions of organic acids, aqueous solutions of salts of inorganic and organic acids, alcohols, phenols, ketones, esters, ethers, amides, nitriles, sulfoxides, nitro compounds, and aqueous solutions of organic compounds. The base material specifically comprises flexible transparent biaxially oriented polyester, although many other base materials are referred to.

[Class 40 (i).] In a mimic diagram of the type comprising an opaque screen having symbols representing station equipment cut out therefrom and having associated therewith groups of differently coloured lamps so disposed behind the screen that they are not directly visible from the front but illuminate diffusing surfaces, the rear of the diagram is subdivided into separate sections by partitions supported on strips secured to the rear of the diagram. As shown in the Figure, the diagram consists of a glass panel 6 having an opaque screen with symbols located adjacent the rear surface of the panel. Vertical strips 13, 14 are adapted to support trays which form partitions for the various compartments, the undersides of the trays being adapted for reflecting the light from the indicating lamps 9 through the symbols in the opaque screen. The trays 10 have upturned edges 11 and where adjacent trays are spaced apart, inverted U-shaped channel members are placed over the edges to prevent interference between the illumination in adjacent compartments. Vertical partitions at the rear of the screen are secured at front and rear to vertical strips supported from transverse members extending between strips such as 13, 14. The vertical partitions may be arranged to provide compartments which taper towards the front panel. To eliminate shadows, wiring associated with the lamps is located in channels 24 adapted to support the lamp-holders. When closely adjacent symbols are provided, the lamps may be provided in compartments which are not immediately behind the respective symbols, but communicate with the symbols by means of light conduits. Each compartment contains a plurality of differently coloured lamps, the different colours indicating the condition of the associated station apparatus. The lamps may be .mounted perpendicular to one another in staggered relationship in order to eliminate shadows. The sides of the front vertical strips 13 are illuminated by the lamps so that in the case of the representation of a bus-bar where no side partitions are provided, the strip appear; unbroken throughout its illuminated length.
