Title: Rubber member of high surface resistivity
Inventor: YOSHIDA HIROSHI
IPC: B32B15/06
Filed: 1989-05-17
Abstract: If member made of rubber containing carbon black and a member made of metal, e.g. aluminium alloy, come into contact with each other in the presence of an electrolytic solution, corrosion of the metal member would proceed. Such corrosion of the metal member can be suppressed by selecting a surface resistivity (surface electric resistivity) of the rubber member at 10<6>  OMEGA  or high, and more preferably at 10<7>  OMEGA  or higher. Such a rubber member in combination with a metal member may be used in motorcars.

Title: Strengthening refractory oxide ceramics
Inventor: GODFREY DAVID JAMES
IPC: C04B35/01
Filed: 1989-06-23
Abstract: High strength refractory oxide ceramics of silicon nitride and silicon carbide become oxidised at temperatures in excess of 1400 DEG C and their protective film of SiO2 forms glasses which flow to reduce the protection. Refractory oxide ceramics of yttria or ceria possess high melting points but are mechanically weak. These may be strengthened by producing the ceramic with upto 50 mole percent of a strengthening material selected from zirconia, silicon carbide, alumina, magnesia, tentalum carbide, zirconium carbide, aluminium nitride or silicon nitride. Zirconia is the preferred strengthening material and is preferably present in its tetragonal crystal form. Uses of the strengthened yttria and ceria ceramics are in relation to heat engine technology.

Title: System for controlling active suspensions of a vehicle
Inventor: MINE ATSUSHI
IPC: B60G17/016
Filed: 1990-05-22
Abstract: In a system for controlling active suspensions of a motor vehicle, having fluid suspensions for the respective wheels, a longitudinal acceleration sensor (14), a lateral acceleration sensor (15), control valves for the respective suspensions, and a controller for producing a control quantity to adjust the control valves to charge and discharge fluid into and out of the fluid suspensions so as to control the vehicle attitude, the reaction force of each suspension is detected and a mean value of the suspension reaction force is calculated to determine the loading condition of the vehicle while the vehicle is driven straight ahead at a constant speed. The control quantity is corrected by a correcting circuit (30c) so as to match the loading condition of the vehicle whereby the vehicle altitude is precisely controlled so as to match the vehicle weight even in such a transient state as acceleration, deceleration and turning. The internal pressure of each suspension may be detected as the reaction force. <IMAGE>

Title: Carton closing resilient clip
Inventor: WHISTON DAVID THOMAS
IPC: B65D5/06
Filed: 1991-02-19
Abstract: The carton-closer is designed for the Tetrapak variety of beverage or foodstuffs carton. it overcomes the cartons' inherent problem of non-resealability, with its attendant problems of loss of freshness, contamination and accidental spillage. The closer is a clip which can be snapped into place on the raised seam at the top of the carton as in Fig. 5. Once in place it will remain there securely but moveably. When the carton is required for use it can be slid back into a position that will not impede the normal functioning of the carton - see Fig 5. When required it can be slid to the position shown in Fig 6, thereby resealing the carton. <IMAGE>

Title: Computer bus system with virtual memory data transfer capability
Inventor: BECHTOLSHEIM ANDREAS
IPC: G06F13/364
Filed: 1993-03-01
Abstract: A high speed bus system with virtual memory data transfer capability is disclosed. The system has particular applications in computer systems which employ peripheral devices. It employs tri-statable signals that are driven both active and inactive, facilitating interfacing the bus to low-power CMOS technology. Signals which have been driven inactive are maintained at the inactive level by passive pull-up resistors after the drivers turn off. The embodiment minimizes the number of lines required to implement the bus and minimizes the amount of time a particular device is required to wait before it can access the bus and complete a data transfer. <IMAGE>

Title: Method and device for biochemical sensing
Inventor: HOLM-KENNEDY JAMES W
IPC: G01N33/543
Filed: 1992-10-20
Abstract: A method and application for detecting and measuring the presence of a binding target material (64) employs a semiconductor device (50) having a receptor-covered surface (90) topgate (60), separated by a dielectric layer (58) from a substrate (56). Receptors (66) attached to this surface exhibit a chemical selectivity function. Binding occurs in a test solution (52), with charge associated with the target material (64) modulating at least one device characteristic. According to the present invention, measurement may occur under dry conditions, at a time and location different from when binding occurred, thus substantially eliminating problems associated with ionic shielding and reference electrodes, so prevalent with prior art wet measurement techniques. Preferably the device (50) includes backgate (62) to which a bias may be applied to restore the devices pre-binding characteristics. Measurement of the restorative backgate bias provides a signal indicating binding of the desired target material. <IMAGE>
