Title: Method of molding skin-covered foamed article
Inventor: OMATA YOUICHI
IPC: A47C7/18
Filed: 1989-06-23
Abstract: A foamed cushion (25), is moulded against only a central portion of a skin member (21), having a peripheral portion (21b) which, during the foaming within the mould cavity, is maintained out of contact with the foam, by folding back around the edged a central mould part (13b) which is movable to clamp it against a seat (15) of a stationary mould part (13). After removal of the moulded foam and skin member from the mould, the unattached peripheral portion of the skin (21b), is turned out to cover the side surfaces of the foamed cushion (25) and attached to a seat frame by clips at its periphery. According to the invention, leakage of foamable material into the skin member between the seat (15) and the mould part (13b), is prevented by a film (24), which is fixed e.g. by heat pressing, to the surfaces of the skin member which confront the foam and the seat (15).

Title: A colour image reading apparatus
Inventor: SHIRATA ATSUSHI
IPC: H04N1/028
Filed: 1989-06-28
Abstract: In a colour image reading apparatus which uses a combination of both directional and non-directional light sources, e.g.red and green LEDs 6 and blue fluorescent lamp 5, directivity is imparted to the light from the non-directional source(s) 5 by a slit plate 13 or a rod lens so that when the reading position changes, as when part of the image 1 is not in intimate contact with the scanner platen 7, the reflected light of the light emitted from the non-directional light source is reduced in substantially the same manner as the reflected light of the light emitted from a directional light source, thereby preventing colour tone deviation which might otherwise occur in use of a mixture of both directional and non-directional light sources. As described lines of image are illuminated by the sources in turn, for detection by a CCD line sensor 3. The non-directional source may be an electroluminescent panel.

Title: Electrically-programmable semiconductor memories
Inventor: MIDDELHOEK JAN
IPC: H01L21/8247
Filed: 1989-09-22
Abstract: Efficient and fast injection of hot carriers into a charge-storage region (11) of an electrically-programmable semiconductor memory is achieved by vertical punch-through of a depletion layer to a buried injector region (2), by application of a programming voltage to a control gate (12) and to the surface of the punch-through region (1). A well- defined punch-through region (1) can be obtained with a higher-doped boundary region (3) at at least one side of the punch- through region (1) to restrict the lateral spread of the depletion layer(s) and prevent parasitic connections. This permits closer spacing of the injector region 2 to other regions of the memory cell in a transistor area (4), and the injector region (2) may adjoin an inset insulating field pattern (29). A compact cell array layout can be formed with a common connection region (8) for the injector regions (2) of two adjacent cells and for either a source or drain region of four other adjacent cells. <IMAGE>

Title: Longitudinal PLZT light modulator
Inventor: STAPPAERTS EDDY A
IPC: G02F1/055
Filed: 1992-10-19
Abstract: A spatial light modulator comprises a plate 32 of non-ferroelectric PLZT ceramic. An array of pixels 38a, 38b, 38c is formed by depositing a reflecting coating 34 in the desired array on one side of the plate. A longitudinal electric field is applied so that the light entering the plate from the side opposite the reflecting coating experiences a polarization- independent refractive index change when the electric field is applied as it propagates parallel to the electric field. The required voltages may be decreased when a partially reflecting coating is deposited on the side opposite the reflecting coating. Grooves 40 in the plate effectively isolate the pixels from electrical and mechanical crosstalk. <IMAGE>
Patent GB-2261087-A (GB)
Title: Faster address calculation in a pipelined microprocessor
Inventor: HINTON GLENN
IPC: G06F12/10
Filed: 1992-10-27
Abstract: A processor includes a mechanism in which logical addresses are translated into physical addresses by a translation lookaside buffer (TLB) 11 within one clock cycle. This is achieved by the TLB translation being performed in parallel with the calculation of the effective address, the effective address being calculated by a "base-plus-displacement/offset" computation. Such a computation usually does not cross a page boundary, that is, the upper 20 bits, which correspond to the logical page number, are the same after the add. Therefore, only the upper 20 bits of the logical address are translated by the TLB, since it is assumed that these will not change. After the add, if the upper 20 bits did not change, then the 20 physical address bits from the TLB plus the lower 12 bits from the address computation are concatenated to produce the complete correct 32-bit physical address within a single clock cycle. If, however, the upper 20 bits did not change then a signal is generated which enables the translation using the correct logical address, as computed by the effective address generation hardware, to be performed. <IMAGE>

Patent GB-923406-A (GB)
Abstract: 923,406. Indicating-apparatus. ANSCHUTZ & CO. G.m.b.H. Jan. 20, 1961 [Jan. 20, 1960], No. 2463/61. Class 106 (4). [Also in Groups XX and XXXVI] A damping mechanism, as shown, for a crossed coil meter introduces a time delay between the rotation of the rotor 2 carrying coils 3, 4, and its support 13 from which it is suspended by a spring 5, torsion of the spring providing the damping action. The indicator disc 12 is attached to the hub of a wheel 9 and is driven by a motor-friction wheel drive 8, 15, 19 under control of a sensing element 7 detecting any difference in position of 2, 3, 4 and disc 12 so that the disc takes up a position corresponding to that of rotor 2. Element 7 is a photo-cell co-operating with a mark on members 2, 3, 4. The supporting member 13 is coupled to disc 12 by an electromagnet 16 and a cam 14 and arm 17. Magnet 16 is energized each time rotor 2 reverses in direction by an output pulse from a drag switch 21 and remains energized for a time interval determined by a relay (not shown) so that during this time support 13 and the indicator 12 are coupled and the former is driven to a position, against the action of brake magnet system 19, 20, in which spring 5 is not under tension. At the end of this period, magnet 16 is de-energized, member 13 uncoupled and held by the brake magnet system so that only indicator 12 will be driven and the torsion produced in spring 5 will act as a damper for rotor 2. The speed or period of operation of the repeater motor may be proportioned to the amplitude of the oscillation. Switch 21 may be replaced by an electric circuit influenced by the output of element 7, and elements 14, 16, 17, 18 may, in this case, be omitted and support 13 coupled rigidly to wheel 9 and indicator 12 and motor 8 operated by a time relay whenever there is a reversal of the oscillation of rotor 2. The invention may also be applied to a compass needle, gyro system or pendulum.

Title: Liquid level sensor
Inventor: SINCLAIR DAVID
IPC: G01F23/296
Filed: 1993-03-05
Abstract: An ultrasonic liquid level sensor has a transducer 68 mounted at the lower end of an aluminium tube 30 that projects upwardly in a liquid tank (4) so that the tube is filled with liquid (6) to the same height as that outside the tube. Internally, the tube has a layer 32 of an acoustically- absorbing plastics to damp the transmission of ultrasonic vibration from the wall of the tube into liquid within the tube. In use, energy is directed up towards the liquid/air interface which reflects the energy back down to the transducer 68. By measuring the time taken between transmission and reception of an energy pulse, it is possible to determine the distance between the transducer 68 and the liquid/air interface, and from this, the depth of the liquid (6). <IMAGE>
