Title: Assembling a ball bearing
Inventor: KAWAMURA KATSUYUKI
IPC: F16C19/18
Filed: 1991-01-25
Abstract: A method of assembling a double-row ball bearing of a preload-type includes the steps of: (a) inserting a plurality of balls in a crescent-shaped gap formed between an outer race and an inner race which is displaced with respect to the outer race; (b) producing a temperature difference. e.g. by heating the outer race 11 by a heating coil 14 to a temperature of 100 - 150 DEG C to expand the outer race; (c) distributing the balls between the races at equal intervals; and (d) disposing the outer race and the inner race concentrically with each other. As a result of the heating step, the negative clearances between the outer and inner races and the balls are reduced or removed, and thus, the distribution of the balls at equal intervals can be achieved without causing flaws by dragging of the balls and without causing indentations in the raceway surfaces and in the surfaces of the balls. <IMAGE>

Title: Display cover
Inventor: LYNCH MICHAEL JOHN
IPC: A47F3/00
Filed: 1991-03-27
Abstract: A display cover (12) for e.g. protecting models or craft items has at least two faces formed from a single shoot of material by bending the material to form a substantially 'U' shaped or 'V' shaped body section (16), to the opposite open ends of which may be attached further shoots (18) of material to complete the cover (12). The cover is of a transparent plastics material.

Title: Video game
Inventor: YAMAMOTO MASAO
IPC: A63F13/45
Filed: 1991-06-21
Abstract: When a player sets the start of the game, the display shows a number of second objects which are fixed for the duration of the game the number of which corresponds to the set degree of difficulty. Thereafter, first objects are generated based at random and are displayed to fall, and the coordinate positions of the first objects are changed by the player operating a controller. When a prescribed number of the first objects and/or second objects of the same type are detected to be continuously aligned in a vertical or lateral direction, the first objects and/or second objects of the continuously aligned state are erased. If there is a first object which has been supported only by the erased first objects and/or second objects, the first object is also displayed to fall. When the second objects displayed on the display means are all erased, it is determined that the game is cleared. <IMAGE>

Title: Optical detection device and optical playback systems
Inventor: WILLIAMS EDWARD WATKIN
IPC: G11B7/13
Filed: 1992-08-20
Abstract: An optical detector assembly (19) comprises first and second position sensitive semiconductor detectors (PSDa and PSDb) each having an edge extending generally in the direction of position sensitivity and being arranged with their respective said edges abutting or in close proximity to each other but electrically separate from each other, whereby a beam of light falling onto the adjacent detectors causes output signals (17,17', 18, 18') to be generated which vary in dependence upon deviation in beam position and1or intensity on the detector regions. The two PSD's may be formed as separate regions on a single substrate or independently on separate substrates. In a reading head for an optical disc track 26, a beam from a laser 21 is reflected by the tracks and deflected by a beam splitter 22 through an astigmatic lens to the pair of detectors. The outputs (17, 17', 18, 18') produce focusing, teaching and data signals in the conventional way. <IMAGE>

Title: Bearings
Inventor: TANAKA TADASHI
IPC: C22C9/08
Filed: 1993-03-29
Abstract: A Cu-based alloy for a sliding material consists essentially of, by weight, 10 - 35% Zn, 2 - 20% Pb, 1 - 10% Ni, 0.1 - 1% B and, as required, 0.5 - 10% of Sn. The alloy may be used under severe conditions at elevated speed and temperatures with reduced risk of seizure and corrosion. The alloy is produced by mixing Pb powder and NiB alloy powder with Cu-Zn powder or Cu-Zn-Sn alloy powder, or mixing Ni-B alloy powder with Cu-Zn-Pb alloy powder or Cu-Zn-SN-Pb alloy powder. The alloy is then compacted and sintered to form a sliding member, or a composite sliding member can be obtained by sintering and integrating the alloy on a steel backing plate optionally having a surface plated with copper.
Patent GB-2267779-A (GB)
Title: Optical amplifier with a filter
Inventor: TAKEDA TOSHIYUKI
IPC: H01S3/067
Filed: 1993-06-02
Abstract: In an optical amplifier a signal light 1 of a wave length  lambda  a is coupled with a continuous light 2 of a wave length  lambda b and amplified by an optical fiber amplifier 4. Then, the amplified output light is subjected to filtration to select the light of the wave length  lambda  a alone. The effect is to reduce ASE power and to increase dynamic range of the optical fiber amplifier from the minimum light receipt power to the saturation after amplification. If the signal light 1 is pulse-modulated, the deterioration of the extinction ratio is minimized. <IMAGE>

Title: A process for manufacturing writing pads
Inventor: MOLLOY PAUL
IPC: B42C19/00
Filed: 1993-11-02
Abstract: Stacks of sheets are prepared and delivered to a loading station (13), each stack comprising a selected number of writing sheets mounted between outer cover sheets. The sheets in each stack are aligned and then conveyed horizontally to a gluing station (40) where hot melt adhesive is sprayed onto a binding edge of the stack. Excess glue is scraped away from the binding edge and the stack is delivered to a taping station (50). A binding tape is fed from a supply reel over a roller which applies glue to one side of the tape. The tape is then aligned with the binding edge of the stack and pressed into engagement with the binding edge and folded around the binding edge. Downstream of the binding station (50) the tape is cut and the stack conveyed to a drilling station (70) where pairs of spaced-apart holes are drilled in the stack. From the drilling station (70) the stack is passed to a guillotine (78) where excess material is cut from free side edges of the stack. The stack is then cut in two to produce a pair of bound writing pads. <IMAGE>

Patent GB-2275207-A (GB)
Title: Talking playset
Inventor: ARAD AVI
IPC: A63H3/52
Filed: 1994-01-31
Abstract: A toy playset includes a doll house 12 with one or more socket type receptacles 31 - 37 located on the floors of each of several rooms. The receptacles interchangeably receive any of three different toy figures (Fig. 5) and form sensors. Each figure has a distinct outer appearance identifying the figure and is uniquely encoded by identifying rings in its base (Figs. 6 and 7) which activate selected switches in any of the receptacles in which it is placed (Figs. 4 and 7). A processor/synthesizer (60 Fig. 8a) powers and polls the status of the switches and identifies through the switches each receptacle receiving a figure and the figure received. The processor/synthesizer generates a unique sound response to the state of the playset in the form of a monologue or conversation, whichever is appropriate. In the case of two or three figures being received in receptacles, the unique sound response also depends upon the order in which the figures were received in the receptacles. The sound response may be further varied depending upon the state of a time switch indicating day or evening and the orientation of any character placed in a receptacle located at the front door of the doll house. Selected sound effects may be generated at any time through a plurality of momentary switches. <IMAGE>

Patent GB-2290155-A (GB)
Title: Automatic winding mechanism
Inventor: LITCHFIELD KEVIN
IPC: G04C1/08
Filed: 1994-06-07
Abstract: An automatic winding mechanism for a clock includes an electric drive motor 18 for imparting drive through shafts 26, 28 to an epicyclic gear arrangement. The latter comprises a sun pinion wheel 30 Fig. 1, not shown, meshing with a planet pinion wheel 34, the latter in turn meshing internally of an outer gear ring 36 which controls an operating mechanism for the clock. The wheel 30 is rotatably mounted on a barrel 44. When the motor 18 is switched off, a weight, hanging from a wire rope which is wound around the barrel 44, unwinds the rope from the barrel 44, so that the latter is rotated and drives the gear arrangement and thereby the operating mechanism for the clock. When sufficient revolutions of the barrel 44 are monitored, the drive motor 18 is actuated and, through the gear arrangement, continues to impart drive to the clock operating mechanism, while rotating the barrel 44 to raise the weight for subsequent weight driving of the clock mechanism. <IMAGE>
