Patent GB-2163616-A (GB)
Title: A memory device
Inventor: MITSUMOTO KINYA
IPC: G11C11/409
Filed: 1985-08-19
Abstract: A memory device in which a switching element (QE1) is interposed between two data lines (D1001, D1001) pairing to each other, that the conduction of the switching element is controlled by a selecting signal applied to other switching elements (Q1001, Q1001) for the data lines, and that when the data lines are in a non-selected state, the switching element is rendered conductive, thereby to reduce the difference of the potentials of the two data lines. Since the potential difference between the pair of data lines is reduced under the non-selected state, the potentials of the respective data lines are rapidly changed to a high level and a low level on the basis of information stored in a memory cell when the non-selected state has been switched to a selected state, so that a period of time in which the information is read out can be shortened.   Moreover, since the switching element is controlled by utilizing the data line selecting signal, any special control signal generator is not required, and circuitry is not especially complicated. <IMAGE>

Title: Circuit for detecting asynchronism in alternating-voltage signals
Inventor: BRANDSTATTER WOLFGANG
IPC: G01R29/18
Filed: 1985-10-02
Abstract: A circuit for detecting asynchronism in two alternating-voltage signals comprises an edge-triggered flip-flop 5 in which one alternating-voltage signal MD is present at the set input and the other alternating-voltage signal SD is present at the clock input, if necessary via comparators 3, 4, and the output of the flip-flop is connected to a low- pass filter 6 at the output of which half the maximum output voltage of the flip-flop can be picked up in the case of asynchronism, as a result of the flip-flop output switching between zero and maximum. The circuit is used in a mains-operated power supply having an isolated secondary (output) side, to detect mains undervoltage/failure from the secondary side. Two DC/AC converters 11, 12 driven by a common AC/DC converter 10 are normally linked W3-W4' to maintain synchronism, but if a threshold circuit 16 detects mains undervoltage the link is broken 15 and the resulting asynchronism signal at AA provides an isolated "mains failure" message. <IMAGE>

Title: Locking arrangement for an actuator
Inventor: TREGONING GEOFFREY ROBINSON
IPC: F15B15/26
Filed: 1985-12-23
Abstract: A lock arrangement for capturing an axially movable member such as the output rod of a linear stroke actuator. The exemplary embodiment consists of a vehicle door actuator. The actuator output rod passes through a lock housing attached to an actuator mounting bracket. Within the housing the output member passes between a pair of pawls which are arranged to pivot in one direction only to allow a collar fixed to the member to pass between them in said one direction. The pawls engage the collar and capture the member preventing its return movement until released. The housing consists of two sections which can be separated slightly to allow the pawls to slide radially outwards and thereby to release the collar. The actuator cylinder is coupled to one of the housing sections and has a limited lost motion relative to the mounting bracket so that when the actuator is energised for release the lock housing sections are separated to free the pawls. <IMAGE>

Title: Particulate spacers for touch sensitive overlay panel applications
Inventor: EPPERSON DAVID LAWRENCE
IPC: H01H13/702
Filed: 1986-08-28
Abstract: Fine particles (53) sized to be within a predetermined size range, are deposited on, and thereafter adhere in random distribution to, one of two adjacent surfaces, serving to keep the surfaces uniformly spaced apart except when an external force causes them to make local contact. The particles are conveniently applied in the form of a spray of a suspension of particles and a fluid carrier material, preferably water with alumina particles, or an aqueous solution of a chloride salt of an-alkaline earth metal such as calcium, potassium or sodium when small glass beads are used as the particles. Brown alumina particles (approximately 96% Al2O3) in the size range 3-50 microns, so utilized, are found well suited as parallel surface spacers in optically transparent touch sensitive overlay (TSO) panels. Particle distribution densities in the range 300-1,000 particles per inch are satisfactory for TSO panels,with the higher particle density requiring a higher actuation pressure to be applied. Applicable to contact-making or optical touch sensitive switch panels. <IMAGE>
