Inventor: HAPGOOD ROBIN
IPC: F16B7/04
Filed: 1995-04-11
Abstract: CLAMPS          ABSTRACT OF THE DISCLOSURE A clamp for connecting together two parallel elongate members has a pair of body parts with respective recesses that can be brought together to define a through-opening receiving one of the members.  To one side of the through-opening each body part has spaced tubular portions with coaxial bores.  The tubular portions of the body parts can be meshed together to align their bores and the other of said elongate members inserted through the bores to lock the body parts together axially but allowing them to pivot on the further member.  To the opposite side of the through-opening the body parts have snap-fastening recesses that engage a clamping lever.  Cam means between the clamping lever and the body parts allow the body parts to be flexed together by pivoting the lever, so gripping both elongate members and locking them together releasably.

Title: Random access memory (ram) based configurable arrays
Inventor: FREEMAN RICHARD D
IPC: G11C11/406
Filed: 1994-03-16
Abstract: A field programmable device includes two separate and electri-cally isolated arrays (11 and 60) of rows and columns of conductors sharing the same area of an inte-grated circuit substrate, one array (11) interconnecting memory cells to form a random access memory (78) ("RAM"). The other array (60) forms a full or partial cross-point switching networt (65) that is controlled by information stored in memory cells, and/or connects to an operating electronic circuit (66) that is configurable and operable in ac-cordance with information stored in memory cells. In addition, the mem-ory array (11) is easily used to ac-cess desired modes of the circuit ar-ray (60) in order to be able to easily observe internal signals during oper-ation. A preferred memory structure is a dynamic random access memory ("DRAM") because of a high den-sity and low cost of existing DRAM fabrication techniques, even though periodic reading and refreshing of the states of the memory cells is re quired. Several circuits (21, 25 and 41) and techniques are used which allow continuous assertion of the memory cell states without interruption during their refreshing cycles.

Title: Apparatus and method for transmitting and receiving ultrasonic waves having an acoustoelectric, ultrasonic transducer
Inventor: ISHIDA YOSHIHIKO
IPC: G01H17/00
Filed: 1995-10-03
Abstract: An apparatus for transmitting and receiving ultrasonic waves has a transmitter for sending a pair of ultrasonic waves to a sample.  The pair of the ultrasonic waves have substantially symmetric waveform with respect to zero sound pressure each other.  One of the ultrasonic waves is separated from the other ultrasonic waves.  An acoustoelectric, ultrasonic transducer receives the pair of ultrasonic waves affected by the sample.  The acoustoelectric, ultrasonic transducer converts the pair of ultrasonic ways into a pair of electric signals accompanied by phonon-charge carrier interaction.  Each of the electric signals includes an acoustoelectric signal insensitive to phase and a piezoelectric signal sensitive to phase.  A processing device processes the pair of electric signals so as to remove the piezoelectric signal and obtain the acoustoelectric signal.  The initial ultrasonic waves have opposite phase so that superimposition of the pair of electric signals by the processing device of offsets the piezoelectric signals, thereby obtAining the acoustoelectric signals.

Title: A method for measuring a fluid level and an apparatus thereof
Inventor: KAWAKATSU HIROSHI
IPC: G01F23/26
Filed: 1996-05-17
Abstract: Switching means SW20 receiving capacitance measurement signals from a control part 35, controls a plurality of switches so as to consecutively measure capacitance between electrodes positioned adjacently. Capacitance values initially measured between the adjacent electrodes are stored in a storing circuit 30, and averaged to calculate an averaged initial value used in calculating correction values which represent differences between the averaged initial value and the initial capacitance values. Actual measured values are corrected using the correction values when detecting a fluid level. It is therefore possible to measure a fluid level without influence of floating items or the like with stability, by utilizing capacitance measured between adjacent electrodes. Also, actual measured values are corrected with the corrected value after measuring initial values, to allow measured substance level detection with high stability and accuracy.
