Patent CA-2200275-A1 (CA)
Title: Single operation detecting apparatus for a distributed power supply
Inventor: KONDO KOJI
IPC: H02J3/16
Filed: 1997-03-18
Abstract: A single operation detecting apparatus for detecting that a synchronous generator of a distributed power supply is switched to single operation from cooperation of the distributed power supply with another power system. It includes a frequency detector connected to a line system of a customer, reactive power regulating equipment connected to the output terminal of the synchronous generator, a fluctuation signal generator for providing periodic small fluctuations to a reactive power setter of the reactive power regulating equipment, and a single operation signal generator for monitoring the output of the frequency detector to output a single operation signal when the monitored output deviates from a range between allowable upper limit and lower limit around a reference frequency. It is possible to detect the single operation by actively disturbing the balance between the energy generated by the synchronous generator and the power consumed by the distributed power supply, when the synchronous generator is disconnected from the cooperation with power system.

Filed: 1995-09-07
Abstract: An extruded PVC clip-on label holder for use on glass shelves such as merchandise shelves in retail outlets has a label holder panel and a pair of resilient rearwardly extending arms forming a channel between which a shelf is gripped. The holder is suitable for use on both thinner and thicker glass shelves by virtue of a step which extends along the base of the channel in one corner. A thinner shelf is gripped between the arms with its front edge fitting over the step and abutting the rear surface of the label holder panel.      A thicker shelf is gripped between the arms with its front edge abutting the step.
Patent CA-2201324-A1 (CA)
Title: High speed flow cytometer droplet formation system
Inventor: VAN DEN ENGH GER
IPC: G01N15/14
Filed: 1995-10-13
Abstract: A droplet forming flow cytometer system (1) allows high speed processing without the need for high oscillator drive powers through the inclusion of an oscillator or piezoelectric crystal (10) within the nozzle volume (3) and directly coupled to the sheath fluid. The nozzle container (27) continuously converges so as to amplify unidirectional oscillations (11) which are transmitted as pressure waves through the nozzle volume (3) to the nozzle exit so as to form droplets from the fluid jet. The oscillator is directionally isolated so as to avoid moving the entire nozzle container so as to create only pressure waves within the sheath fluid. A variation in substance concentration is achieved through a movable substance introduction port (9) which is positioned within a convergence zone (32) to vary the relative concentration of substance to sheath fluid while still maintaining optimal laminar flow conditions. This variation may be automatically controlled through a sensor and controller configuration.    A replaceable tip design is also provided whereby the ceramic nozzle tip is positioned within an edge insert (29) in the nozzle body (24) so as to smoothly transition from nozzle body (24) to nozzle tip (25). The nozzle tip is sealed against its outer surface to the nozzle body so it may be removable for cleaning or replacement.

Title: Method of transmitting clock signal and device employing the same
Inventor: FUGO MASATOSHI
IPC: H03K5/1532
Filed: 1997-04-25
Abstract: A frequency divider 1 on the transmitting side divides the frequency of a clock signal of period T by 8, generates a pulse signal P2 of pulse width 4T and duty ratio 50%, and outputs the result to a shift register 2. The shift register 2 generates pulse signals P3-1, P3-2, P3-3, and P3-4 by giving delays 0, T, 2T, and 3T to the pulse signal P2, and sends them to transmission lines 101, 102, 103, and 104, respectively.  Edge detectors 3-1, 3-2, 3-3, and 3-4 on the receiving side detect respectively the leading edges and the trailing edges of the pulse signals P3-1, P3-2, P3-3, and P3-4, and output edge detection signals P4-1, P4-2, P4-3, and P4-4.          An OR gate 4 combines these edge detection signals.          A clock regenerator 5 generates a regenerated signal P6 having the frequency equal to that of the clock signal P1 based on the combined edge detection signal P5.
