Patent GB-2254157-A (GB)
Title: Testing printed circuit boards
Inventor: KOJIMA TATSURU
IPC: H05K3/00
Filed: 1992-03-27
Abstract: A printed circuit board (10) allows the characteristic impedance and wavelength compaction ratio of microstrip lines (not shown) on a main circuit part (12) to be determined without disconnecting the lines from surrounding circuitry. As shown, a strip conductor (18) on an auxiliary part (14) has a land (20) for measurement at one end thereof and chip lands (22, 24) connectable to a chip resistor (24) at the other end. The results obtained for the strip conductor (18) will thus be the same as those that would be obtained for microstrip lines on the main part (12). The strip conductor (18) and lands (22) may be arranged on the main board part (12) without the auxiliary part (14). <IMAGE>

Title: Concrete slab and a method of fabricating a floor using the concrete slab
Inventor: JARVI JOUKO UOLEVI
IPC: E04B5/36
Filed: 1992-04-29
Abstract: A concrete slab has an axis (5) extending between first and second ends (6) of the slab and an upper face (3) having a first set of abutment surfaces (9) arranged to abut against engagement surfaces of an overlying concrete topping to prevent axial slippage at the interface between the slab and the topping. The concrete slab (1) may be used to form a floor by positioning the concrete slab at the desired location in a building and then casting the concrete topping on top of the slab. The slab acts as shuttering for the concrete topping. <IMAGE>

Title: Dental adhesive composition
Inventor: SAKUMA TETSURO
IPC: A61K6/00
Filed: 1992-07-14
Abstract: A compound having a carbodiimide in its molecule is incorporated in a dental adhesive composition. With this composition, dental composite material can be firmly bonded to the enamel and dentin of a tooth, thereby avoiding formation of a gap which may otherwise cause secondary caries. The adhesive composition may comprise a methacrylate or acrylate monomer having at least one unsaturated double bond and a polymerization initiator. The adhesive may be photopolymerized or chemically polymerized, and may include fillers and/or solvents. Suitable carbodiimides are dicyclohexylcarbodiimide, 1 ethyl-3-(3-dimethyl-aminopropyl)carbodiimide and 1-cyclohexyl-3-(2-morpholinoethyl) carbodiimide.

Title: Filmless radiography device
Inventor: SCHONARTZ NORBERT
IPC: B23K31/00
Filed: 1994-01-20
Abstract: The device is for testing the welding of extended, welded hollow structures made of metal, in particular steel pipes. The device comprises a liquid-cooled X-ray tube (3) which can move in the hollow structure (12) and is connected to a high-tension generator (8) by means of cables (11). An X-ray iconoscope (16) is located in the irradiation area of the X-ray tube (3).

High-tension cable(s) (11) are connected to the X-ray tube (3) via guide means (4, 5) disposed outside of the hollow structure (12). The length of the cable(s) (11) is such that the X-ray tube (3) can move from one end to the other of the longest hollow structure (12) to be tested. The device is suitable for hollow structures with a short inside diameter and having lengths of more than twelve metres. Further, it is sufficient for the concrete shielding to have a length which is only slightly greater than the longest hollow structure to be tested. <IMAGE>

Title: Fishing rod holder and hook setter
Inventor: FLISAK RONALD GERALD JOHN
IPC: A01K97/11
Filed: 1994-03-14
Abstract: The device includes a tube 10 for holding a fishing rod, which pivots to an at-rest position under the action of a main spring 14. The tube is held in an at-ready position by a latch 33. The latch is tripped by a tug on the fishing line. A safety-catch 47 is automatically cocked, when the fisherman sets the tube, to a position where the safety catch blocks the latch, and prevents the latch from tripping. This enables the latch 47 to be set automatically also when the fisherman sets the tube. The safety catch is released by hand when the device has been fully prepared and adjusted. <IMAGE>

Title: Video printer using a thermal printing head following a curved cam surface
Inventor: KIM JONG-WOO
IPC: B41J19/20
Filed: 1994-03-25
Abstract: A printer for a video is disclosed, the printer comprising a plate-like platen 1, upon which paper 9 is clamped, by means of paper holders 2. A colour ribbon 8 is disposed between the paper 9 and a printing head 3. The printing head 3 is mounted on a bracket 7 which includes a follower 6 arranged to travel on a curved guide path 5. In use, when the follower 6 is between positions B and C on the guide path surface 5, the head 3 may cause colour to be transferred from the ribbon 8 to the paper 9, in response to a printing signal. The head 3 is raised from the paper when the follower is in either of positions A or D. The follower 6 may follow path B to C or C to 13 a number of times so that, in each pass, a different colour may be transferred to the paper and a coloured image may thereby be printed.   <IMAGE>

Title: A field effect transistor and a production method
Inventor: FUJITA KOICHI
IPC: H01L21/336
Filed: 1994-04-22
Abstract: The device comprises a double diffused type MOSFET having a lightly doped drain (LDD) 4b. An embodiment where the distance separating the source contact region 6b and the gate region 3 is less than the distance between the drain contact region 6c and the gate region 3 is described. Due to the impurity diffusion layer 7 having the same conductivity type as the substrate 1 and a higher impurity concentration than the substrate, an improvement in the drain-source breakdown voltage, suppression of the variations in the threshold voltage, and reductions in the gate-source capacitance and gate-drain capacitance are attained. <IMAGE>

Title: Liquid crystalline copolymer
Inventor: PARRI OWAIN LLYR
IPC: C08F220/30
Filed: 1994-06-30
Abstract: The invention relates to copolymers made from mono reactive liquid and/or di reactive liquid crystals which can be photopolymerised to form copolymers and to novel reactive liquid crystal compounds having a nematic phase. Preferably the reactive liquid crystal is polymerised while in the liquid crystal phase to produce an oriented birefringent polymer film. To do this the reactive liquid crystal, in its nematic or smectic phase is aligned (by well known techniques such as rubbed polyimide etc.) and the thin film containing a small amount of photoinitiator, is subjected to ultra-violet light whereupon it polymerises into a thin, aligned polymer film. Some of the monomers are claimed to be novel.

Title: Power saving arrangement in a mobile telephone
Inventor: LANSDOWNE RICHARD
IPC: H04W52/02
Filed: 1995-02-07
Abstract: A mobile telephone has a high frequency system clock (41) and a processor (61) arranged to process polling signals received while the telephone is in its standby condition. When polling signals are not being received, it is possible for the telephone to be placed in a sleep condition, by de-activating the system clock. Re-activation occurs in response to a calibrated number of clock cycles produced by a lower frequency sleep clock (65). Upon re-activation, system clock counters (43,44), specifying sub-frame periods and frame periods are re-loaded so that they may be re-activated at the required phase. The phase of these counters is compared with signals received from base stations and modifications are made to system counts as required. The extent to which modifications are required is also used to re-calibrate the sleep clock. <IMAGE>

Title: An impact dot printer having a gap adjusting device
Inventor: IKEHATA TSUTOMU
IPC: B41J25/308
Filed: 1996-04-12
Abstract: A printer (P,Fig.3) having a printhead (10) and a platen (18) comprises a gap adjusting device (GG) which moves a print head (10) vertically via a carriage shaft (17) eccentrically supported by a displacement gear (42). The displacement gear (42) is provided with a gap lever (45) movable between stop members (48a) and (48b), which restricts rotational movement of a driving force transmission mechanism (40) by abutting on the stop (48a) when a pulse motor (41) drives the print head (10) to move away from a platen(18). The pulse motor (41) becomes out of phase, thereby defining this position as a reference position. The amount of rotation of the pulse motor (41) is adjusted, starting from the reference position, thereby adjusting a vertical position of the print head (10). The reference position of the print head (10) is established without the risk of causing damage to dot pins, by defining an initial condition of the pulse motor (41). The width of a gap (G) is controlled via a controller (19,Fig.2) according to the print media thickness detected by a print media thickness detector (27,Fig.5) including a photo sensor (31,Fig.5).
