Title: Loading device for a tape recorder
Inventor: KIM DONG-KYU
IPC: G11B15/675
Filed: 1989-08-16
Abstract: A loading device for a tape recorder provides the loading of the tape cassette and the tape winding by a single loading motor. The separate driving motor which has been used previously only for tape loading in conventional loading devices of tape recorders is thus excluded. A change gear 12 and its guide hole 101, which transmit the driving force of a loading motor 2, conveyed through a worm 3 to connection gears 14 and 15 of the tape loading device, are formed at a specified position of the deck between the conventional tape loading mechanism (including loading arm 21 and ring gear 18) and the conventional driving force transmitting mechanism for cassette loading (including speed reduction gear group 5, 6 and 7 and rack 9). <IMAGE>

Title: Snooker/pool aim trainer
Inventor: JACK DONALD BRIAN
IPC: A63D15/00
Filed: 1989-10-28
Abstract: The aim trainer comprises a stationary object ball 12, a stationary cue ball 11 and, rotatably mounted on the object ball, an aim indicator 15 and target 24.

Title: Making superconductive components by electrodeposition
Inventor: HUR PIL HWA
IPC: B21F19/00
Filed: 1990-08-31
Abstract: A method of making a superconductive component is disclosed. A tank 21 is filled with an electrodeposition solution 22, and a plurality of rollers 12-15 guide a substrate 19, which may be wire- or web-shaped, through the electrodeposition solution within the tank. A pair of electrodes 17, 18 is installed, one (18) being in contact with the electrodeposition solution and the other (17) with the substrate in order to apply a voltage to the substrate running through the electrodeposition solution. As a result superconductive material contained within the electrodeposition solution is electrodeposited on the running substrate 19 for carrying out the method, and superconductive compositions, are also disclosed. A substrate e.g. running wire 19 is immersed in a solution of a superconductive material in HNO3 and a voltage applied e.g. between electrodes 17, 18 to electrodeposit the superconductive material on to the substrate. This process is simple and also avoids the deterioration in characteristics produced by some heat-treatment or drawing processes. The superconductive material can be: i)  alpha 1-x beta x R2 Cur O7-8 where  alpha  is lanthanum series metal,  beta  is K, Li, Na or Ca, R = Ca, Sr, or Ba and 0 </= x </= 0.5, r=3 or 4,0< delta <1; or ii)  alpha m  beta p  gamma q Cur Oy (where  alpha  = Bi, = Sr,  gamma = Ca and either m = 2,0 </= p </=9,1 </= q < 10, r = q + 0.5 x (0 </= x </= 10) and y = 3 + p + q + r; or m = 4,p + q = 7 + 2x with 0 </= x </= 9, p/q = (3+n) / (7-n) With 0 </= n </= 4, r (p + q + 3)/2 and y = (p + q + 5) 3/2. <IMAGE>

Title: Monopole antenna.
Inventor: CHU MICHAEL WAH CHEUNG
IPC: H01Q9/40
Filed: 1990-09-17
Abstract: A broadband monopole antenna comprising a radiating element extending vertically with respect to a horizontal ground plane (2). The radiating element comprises upper (6) and lower (5) conductive sheets carried on opposite main faces (7, 8) of a dielectric substrate (1). The two sheets (5, 6) are separated by a narrow slot (10) parallel to the ground plane (2). The lower sheet (5) is connected along one edge (9) to the ground plane (2), whereas the upper sheet (6) is connected to a stripline feed (4) with which it forms a continuous conductive layer. The capacitance of the slot (10) at the feed point maintains a low input impedance for the antenna over a wide frequency range. The antenna produces radiation patterns substantially the same as a conventional monopole whip antenna, but offers a superior impedance match bandwidth in excess of 5:1 with VSWR less than 2.5:1. The antenna is conveniently fabricated using microstripline circuit board.

IPC: E01C5/20
Filed: 1991-10-11
Abstract: A tile shown generally at 10 has a square body portion 11 and leg portions 12 at each corner thereof. The tile 10 is moulded from plastics material and has reinforcing webs (13, 14), (shown in broken lines in figure 2) on its underside and downwardly extending flanges 15 at each of its four edges. The leg portions 12 are tapered to provide sharp spikes for penetration into the ground in use. The upper surface of the body portion 11 comprises a moulded inset portion 16 having a coarse texture (not shown) so as to provide grip for a person walking on the tile 10. The coarse texture is incorporated in the inset portion 16 during moulding of the inset portion 16.

Title: Two-colour image reader with reduced grey sensitivity
Inventor: OHTA EIICHI
IPC: H04N1/56
Filed: 1991-12-16
Abstract: In an optical image reader black and red portions of an original are distinguished from each other, and from the original base colour (white) by successively illuminating the original with yellow and red light. Light reflected from the image is converted into electric signals. and the colour of a pixel determined by thresholding and logic means. In order to prevent grey spots from being recognized as red, the sensitivity of the red reading system is made lower than that of the yellow reading system (the red light can be of lower intensity than the yellow light, or the amplification of the red signal can be lower than that of the yellow signal). if grey spots are determined to be non-white, the reduced sensitivity of the red signal channel will cause them to be recognized as black rather than red, leading to a more natural looking image. <IMAGE>

Title: Windscreen washer pump
Inventor: SATO TOSHIHIRO
IPC: B60S1/48
Filed: 1991-12-17
Abstract: A cylindrical peripheral wall 25 is formed by extending the peripheral wall of the pump inlet (15) upward so that the upper end of the cylindrical peripheral wall (25) serves as the opening thereof to cleaning liquid 10; and a flow passage 26 serves as a through-hole provided on the cylindrical peripheral wall 25 at a lower portion thereof. Preferably, the through-hole 26 is provided on the cylindrical peripheral wall 25 such that the height H3 of the through-hole 26 is almost the same as that H2 of the inlet 15 or below the inlet 15. The through-hole 26 may consist of a groove (40 Fig 4, 5) vertically extending in the direction from the upper end of the cylindrical peripheral wall 25 toward a lower portion thereof. Thus, the interior of the washer tank 11 communicates with the interior 25b surrounded with the cylindrical peripheral wall 25. The arrangement is such that when the liquid level is reduced and the pump operated the liquid delivered is reduced and when re-operated after a break in pump operation the liquid delivered appears normal again to thereby warn the driver that the washer tank 11 needs re-filling without opening the vehicle bonnet. <IMAGE>
