Abstract: A flat bag closure (17) of the type having at its edge a V-notch (12) which communicates at its base with a bag neck gripping aperture (14). The closure is made of a non-frangible material so that it can fold along an axis (20) aligned with said notch and said aperture without breaking. The closure thus can be repeatedly bent along such axis to facilitate repeated insertion and removal of a twisted poly bag's neck (36) into and from the aperture. The axis may contain a hinge formed by perforations (19, 24, 26, 28, 30), a concavity (22), or slits (32, 34) to facilitate bending.

Abstract: An optical recording method comprises writing in a ferroelectric material heated at or above the glass transition point, and holding the resultant written state below the glass transition point. Preferably, the ferroelectric material constituting the optical recording layer has an optical thickness capable of providing a multiple reflection state.

Abstract: A valve member (E) for a shut-off valve has a stem tip seal (F) and is adapted for selective movement axially towards and away from an associated valve seat (76). A generally cylindrical sleeve (80) is carried by the valve member (E) and has an end defining an outer annular seal surface (91) adapted for cooperative sealing engagement with the seat (76). Mounted centrally within the sleeve (80) for limited axial movement is a rigid cylindrical body (88) that defines an inner annular seal surface (90) adapted for engagement with the seat (76) at a location radially inwardly of the outer annular seal surface. Formed between the sleeve (80) and the rigid body (88) is an annular chamber (96) which opens axially inwardly from a narrow slot (94) located between the inner annular seal surface (90) and the outer annular seal surface (91). A mass of resilient packing material (97) substantially fills the chamber (96) and extends axially outwardly of the slot (94) to define a medial annular seal surface (103). Means are associated with the rigid body (88) for generating pressure on the packing material (97) when the body is forced axially towards the valve member (E). In addition, the inner annular seal surface (90) is configured to engage the seat (76) prior to engagement by either the medial annular seal surface (103) or the outer annular seal surface (91).

Abstract: Amemory cartridge is loaded in a main unit of a personal computer when used. The memory cartridge comprises a case, and a printed circuit board which is installed therein and on which a large-capacity, one-chip ROM is mounted. Storage area of the one-chip ROM is divided into a plurality of banks respectively having memory addresses of a number accessible by a central processing unit of the main unit, and one specific bank among them is allocated to an address space accessible all the time by the central processing unit. Bank selecting data for selecting other banks is stored in that specific bank. The bank selecting data is read out with progress of a program stored in the specific bank, being loaded in a counter. The content of the counter is inputted to the most significant three bits of address of the one-chip ROM. 
     The most significant three bits of the address function as bank designating bits. An arbitrary bank of the one-chip ROM is changed over at an arbitrary timing by the bank selecting data outputted from the other banks of the one-chip ROM.

Abstract: The present invention provides a digital communication system in which one time slot is divided into a first half section and a second half section and the carrier phase difference e between each neighboring first half sections is set to either (π, 0) with respect to a binary information symbol (1, 0) or (0, π/2, π, 3/2n) with respect to a quaternary information symbol (11, 01, 00, 10). In addition, the phase difference ψ between the first half and the second half of any time slot is a constant value ψ0 (for example, π rad) irrespective of the symbol, or ψi determined with respect to a symbol (for example, + n/2 with respect to a symbol 1 or -π/2 with respect to a symbol 0). Therefore, an arbitrary complementary characteristic can be obtained when differentially demodulated in a multipath fading channel, irrespective of the amplitude characteristic of a demodulation signal.

Abstract: 2.1.  In installation systems with automatic screw connection, satisfactory screw hardware is needed. In the past, defective screws have usually been eliminated manually or by costly optical sorting devices. The new sorting device is intended to single out defective fixing components reliably and economically. 
<??>2.2.  Defective components are sorted out from the dimensionally accurate fixing components by a consecutive arrangement of mechanical measuring stations (10, 13) and electrical measuring stations (21, 22, 25) which operate by the eddy current principle, and by ejector devices (10, 12, 3). The mechanical pre-sorting largely prevents dimensional errors from being compensated at the electrical measuring stations. As a result, very high reliability of the overall installation is achieved. 
<??>2.3.  The sorting device is suitable for automatic installation systems for feeding screws to screw pumps. It can also be used, for example, by screw manufacturers for the provision of satisfactory screw hardware.

Abstract: For use in recognizing an input pattern consisting of feature vectors positioned at a first, "" an i-th, ..., and an I-th pattern time instant along a pattern time axis, a connected word recognition system comprises first through N-th neural networks B(1) to B(N) which are assigned to reference words identified by a first,..., an n-th, ..., and an N-th word identifier and are arranged along a signal time axis divisible into a first, ..., a j-th, ..., and a J-th signal time instant. The n-th word identifier n corresponds to consecutive ones of the pattern time instants by a first function n(i). The time axes are related to each other by a second function j(i). Among various loci (n(i), j(i)) in a space defined by the word identifiers and the time axes, an optimum locus (n̂(i), ĵ(i)) is determined to maximize a summation of output signals of the respective neural networks when the consecutive pattern time instants are varied between the first and the I-th pattern time instants for each word identifier. The input pattern is recognized as a concatenation of word identifiers used as optimum first functions n(i) in the optimum locus. Preferably, the optimum locus is determined by a dynamic programming algorithm. If possible, use of a finite-state automaton is more preferred.

Abstract: A programmable protocol engine having a core central processor that implements a plurality of programmable finite state machines that perform context-dependent operations, and programmable satellite processing units that perform context-free operations. To assist in buffering the two way communications of the protocol engine, a memory is included which interacts with the central processor and the satellite units. The programmability of the protocol engine is achieved by realizing the satellite units with combinations of a processing unit and a memory unit which stores the instructions to be performed by the corresponding processing unit. The sequence of instructions to be performed is drawn from a small unique set of instructions which are adapted particularly to the tasks associated with protocol implementations. Instruction ports are provided for loading the necessary instructions to the satellite units and the central processor, thereby implementing a chosen protocol. To permit use of the protocol engine in environments where a plurality of users are multiplexed onto a single physical link, additional means are provided for storing the state of the finite state machines within the central processor, and for restoring the finite state machines to a previously stored set of states.
