Each auxiliary control unit includes local control means for generating local control signals from the master control signals which are synchronised with the local control signals of other auxiliary control units, for initiating operation of the delay devices, so that a large blast can be carried out in a perfectly synchronised manner. The master control unit may transmit master programming signals to the auxiliary control units, which each program the electrical delay devices of their respective group. Synchronisation of the local control signals can be achieved in a number of different ways.      A method of activating a plurality of groups of electrical loads is also described.

Title: Ink jet recording apparatus provided with means for calculating waste ink amount, and information processing system provided with such an ink jet recording apparatus
Inventor: UCHIKATA YOSHIO
IPC: B41J2/165
Filed: 1994-01-14
Granted: 1999-10-19
Abstract: In an ink jet recording apparatus having recovery means for executing the recovery operation of the recording head by discharging ink from the recording head and waste ink storage tank to store the ink exhausted by the recovery means, the amount of waste ink currently stored in the waste ink storage tank is calculated in accordance with the exhaust amount which is exhausted by said recovery means up to the present, the elapsed time since the last recovery operation, and the amount of ink exhausted by the current recovery operation. In this way, it is possible to accurately monitor the amount of ink stored in the waste ink storage tank so that no waste ink is allowed to flow out from the waste ink storage tank. Users can be informed of overflow of the waste ink from the waste ink storage tank to exchange the tank so that a space for the tank can be reduced.

Granted: 2005-04-26
Abstract: A module for insertion into a combined signal and power carrying line, especially into a CATV line, for protecting a system associated with the line from an overcurrent comprises (i) a housing (50)having connection ports (51, 52) for cables (53,54) forming the line and being, impedance matched to the line, one of the conductors of the cables being connected together via a capacitor (23); and (ii) a solid-state overcurrent protection circuit that is connected, across the capacitor via inductors ~ to isolate it from the signal on the line, the protection circuit being capable of switching from a conducting to a blocking state in response to an overcurrent and being capable of resetting itself or attempting to reset itself into its conducting state one or more times after it has switched into its blocking state. If line containing a number of such modules is subjected to an overcurrent, the protection device in the nearest module upstream will switch so that only that part of the line downstream of the module will be affected. In addition, tracing the location of the fault is much simpler because the section of the line in which the fault occurred is known from the protection circuit that has tripped.

Abstract: In a DS/CDMA receiver, each of first and second receiving units (211 and 221) receives a DS/CDMA signal as a received signal. First and second adaptive interference cancellers (212 + 213, 222 + 223) are connected to the first and the second receiving units, respectively.      Each of the adaptive interference cancellers cancels an interference on they received signal. Connected to the first and the second receiving units and to the first and the second adaptive interference cancellers, a single interference canceller control circuit (204) controls the first and the second adaptive interference cancellers in common. An all output. combiner (201) combines all of output signals of the first and the second adaptive interference cancellers. Preferably, each of the adaptive interference cancellers has an adaptive filter (212 or 222) to cancel. the interference with respect to all other stations by adaptively making its tap coefficients orthogonal to spreading codes of the all other stations. Each of the adaptive interference cancellers further has a differential detection circuit (213 or 223) to compensate for phase fluctuation of an output signal of the adaptive filter. The single interference canceller control circuit may control the adaptive interference cancellers in common on the basis of best quality control information relating to one of the received signals of the first and the second receiving units that has a best signal quality.

Abstract: An optical wavelength filter has a polarizer, an analyzer, and an optical waveguide, formed in a substrate displaying an acousto-optic effect, that guides light from the polarizes to the analyzer. A transducer formed on the substrate excites a surface acoustic wave, thus creating an acoustic beam. The amplitude of the surface acoustic wave is small at the two sides of the acoustic beam and larger in the middle. The optical waveguide enters the acoustic beam at a point on one of the two sides of the beam, then moves into the center of the beam, and exits the beam at another point on one of the two sides.
