Patent GB-2253092-A (GB)
Title: Semiconductor memory device
Inventor: LEE KYU-PIL
IPC: H01L21/8242
Filed: 1991-09-03
Abstract: In a semiconductor memory device with a stacked capacitor, when misalignment occurs in forming a contact region 42 for contact between the storage electrode 50 of the stacked capacitor and a source region 34, ions of the same conductivity type as that of the source region are implanted to form another source region 48 under the surface of the contact region 42. In a modification, a successive ion-implantation provides a second diffusion region (58, Fig 5) surrounding the other source region 48. The second diffusion region has a dopant concentration which is higher than that of the substrate 30 and lower than that of the source region 34 and is of the same conductivity type as the substrate 30. On the other hand, when no mis-alignment occurs the semiconductor memory device further comprises a diffusion region (58a Figure 6) formed below the source region, the diffusion region being of the opposite conductivity type to that of the source region. Thereby, a memory device is provided with an improved refresh characteristic and decreased soft error rate. <IMAGE>

Patent GB-2271071-A (GB)
Title: Guiding rolled product
Inventor: TAZOE NOBUHIRO
IPC: B21B39/14
Filed: 1993-03-24
Abstract: Apparatus for preventing lateral curving in a rolled slab 1 comprises a first side guide 5 upstream at the entrance to an edging mill 2, a second side guide 6 downstream at the exit of a horizontal mill 3 and a third side guide 7 between the edging and horizontal mills. The first side guide 5 synchronously closes upon the entry of the rolled slab 1 into the first side guide, leaving a narrow space between the guide and the rolled slab. The third side guide 7 closes the separation spacing the instant the tail end of the rolled slab 1 passes through the edging mill 2. The second side guide 6 assumes a narrow separation distance when the head end 11 of the rolled slab 1 enters therebetween. The restraining force provided by the narrow separation distance prevents lateral shifting during the rolling process thereby reducing snaking of the rolled slab. <IMAGE>

Patent GB-2279623-A (GB)
Title: Collapsible steering column assembly
Inventor: HANCOCK MICHAEL THOMAS
IPC: B62D1/19
Filed: 1994-01-21
Abstract: The assembly has means to absorb energy transmitted by the steering column upon collapse, including a deformable U-shaped wire clip 7 engaged around a pair of pins 10. A skid member 9 adjoins the clip 7 and is coupled to the steering column so that, upon collapse of the steering column, the skid member is urged in a direction to deform the wire clip by drawing it over the pins 10. The clip and skid member are accommodated in a fixed mounting bracket 8 for the steering column. In an alternative embodiment (Figs. 5, 6), the pins (10A) are secured to a moveable plate (12) so that the plate moves upon vehicle impact to straighten the two wires (7A) around the pins, one end 15 of each wire being secured in a fixed plate (13). <IMAGE>

IPC: F03C1/40
Filed: 1994-06-02
Abstract: A pressurized fluid mechanism, which is a reversible motor or pump having two operating cylinder capacities, has a capacity selector device. The capacity selector device comprises two valves (33 - 38, 34 - 39) each having a body with two grooves (33A - 33B, 34A - 34B) and a sliding slide valve (38, 39) with only one groove (44, 45).

Title: Speech compression and reconstruction
Inventor: SINISALO ARI
IPC: G10L19/02
Filed: 1994-07-12
Abstract: The present invention relates to a method with which a speech signal can be compressed, respectively reconstructed, with the aid of two-dimensional algorithms developed for image processing. Both the compression and reconstruction can be thought of being formed from two different phases. In the first phase from a one-dimensional speech signal a two-dimensional image matrix (spectrogram) is formed in which the frequency components of a speech signal transformed from time domain to frequency domain with e.g. Fast Fourier Transform algorithm are presented frame by frame as a function of time. In the second phase of the method the image presented by the image matrix is compressed with a powerful two-dimensional compression algorithm, e.g. by JPEG. The reconstruction of speech is performed in inverse order; decompression (IJPEG) and inverse FFT (IFFT). The method is particularly appropriate for storing and transmitting speech when no strict real time properties are necessitated in the transmission or storing. <IMAGE>
Patent GB-2294855-A (GB)
Title: Needle destroyer
Inventor: ZANADO PHILIPPE
IPC: A61M5/32
Filed: 1994-09-16
Abstract: To destroy a needle 40, a current is first passed longitudinally through the needle as the needle is pressed between electrode portions 21c, 22a of electrode assembly 20, the needle progressively melting to leave just a stub which is then destroyed by passing a current transversely between electrode portions 21b, 22c. Waste material may be arranged to fall into a compartment 8, a gate 25 to which is opened when power is supplied to the electrodes. The needle destroyer may be powered by rechargeable batteries housed in a main body to which a cassette containing the electrodes and the waste compartment may be removably fitted. <IMAGE>

Title: A device for deriving an oscillating force
Inventor: LAURIE PETER CHARLES SOMERVILL
IPC: F03G7/00
Filed: 1994-10-28
Abstract: A device in which, two adjacent Casimir cavities are formed. The central partition is repeatedly switched from a reflecting to a transparent state. When it is in a reflecting state the outer walls are allowed to move inwards under the Casimir force, doing useful work. When it is transparent the two cavities become one with a larger plate separation. The walls are drawn outwards against a lower force, since the Casimir force is inversely proportional to the fourth power of the distance between the plates. The device therefore produces a net energy gain. A number of these devices can be stacked to increase the effect. A stack of devices may be fabricated in a block by the successive deposition of suitable conducting, semiconducting and insulating layers.
