Patent CA-2084722-A1 (CA)
Title: Information Recording and Reproduction Apparatus
Inventor: TERASHIMA SHIGEO
IPC: G11B27/034
Filed: 1992-12-07
Abstract: An information recording and reproduction apparatus has a recording-use memory and a reproduction-use memory. The reading speeds of the respective memories are set so as to be equal to the reading speed derived from the carrier central frequency of the absolute address which is pre-recorded on a disk based on the constant linear velocity control method. With the arrangement, the simultaneous recording and reproduction of information with respect to different portions on the disk is carried out at a high speed without changing the rotation speed of the disk.

Title: Temperature abnormality detecting structure for fluid pipe
Inventor: AMANO KAZUO
IPC: G01M3/00
Filed: 1993-02-10
Abstract: A temperature abnormality detecting structure for a fluid pipe detects a temperature abnormality location by laying an optical fiber serving as a temperature detecting portion of a Ramam scattering optical fiber distribution type temperature sensor along a fluid pipe.          The fluid pipe is divided into a plurality of sections in the longitudinal direction, independent optical fibers are laid along the fluid pipe in the respective sections.  A portion of the optical fiber laid along one of the adjacent sections is superposed to be laid on a portion of the optical fiber laid along the other of the adjacent sections in the vicinity of each of the respective boundaries of the sections.  Since the portion of the optical fiber laid along the pipe of one of the two adjacent sections is superposed on the portion of another optical fiber laid along the pipe of the other of the adjacent sections, if an abnormal temperature change occurs due to a trouble such as leakage or outflow of the fluid from the pipe in the boundary area, the temperature change peak position, i.e., the abnormality occurrence locations is detected by the two different optical fibers.  Thus, the detecting accuracy is remarkably enhanced as compared with a case wherein the abnormality is detected by only one optical fiber.

Title: Differential latching inverter and random access memory using same
Inventor: VINAL ALBERT W
IPC: G11C11/419
Filed: 1992-05-28
Abstract: A differential latching inverter uses a pair of cross-coupled inverters having a skewed voltage transfer function to rapidly sense a differential signal on a pair of bit lines in a random access memory and provide high speed sensing during a read operation. The differential latching inverter may also include a pair of symmetrical transfer function output inverters and additional pull-up circuits to enhance high speed operation. The differential latching inverter may be used in a memory architecture having primary bit lines and signal bit lines, with a differential latching inverter being connected to each pair of signal bit lines. The primary bit lines and signal bit lines are coupled to one another during read and write operations and decoupled from one another otherwise. The read and write operations may be internally timed without the need for external clock pulses in response to a high speed address change detection system, and internal timing signals generated by delay ring segment buffers. A high speed, low power random access memory may thereby be provided.
Patent CA-2110245-A1 (CA)
Inventor: FITE WAYNE C
IPC: H04M15/00
Filed: 1993-11-29
Abstract: A tone burst generator where a continuous tone voltage is applied across two series-connected semiconductor switches each having an ON state and an OFF state. A first control circuit controls the state of the first switch and the variable impedance in an intermediate region between its ON and OFF states to cause gradual, well-defined OFF/ON and ON/OFF transitions of the first switch. As a result of these first switch transitions, a voltage tone burst is generated that has precisely defined edges to eliminate clicking noise. The continuous tone voltage is of only one polarity--it has a non-zero DC component and an AC component having a peak-to-peak variation less the twice the magnitude of the non-zero DC component. A second control circuit controls the state of the second switch and the variable impedance in an intermediate  region between its ON and OFF states to cause well defined ON/OFF and OFF/ON transitions of the second switch. The second switch OFF/ON transition reduces the voltage tone burst to have a substantially zero AC component.
