Inventor: SHIGEMURA KOJI
IPC: B41J2/16
Filed: 1996-10-08
Abstract: A multinozzle ink jet recording device having a dense arrangement and a method of producing the same are disclosed. Two electrodes for applying a voltage to the side walls of a piezoelectric plate lie in the range of a pressure chamber, so that an electric field is prevented from acting on portions which do not contribute to the ejection of an ink drop. This obviates the waste of voltage and thereby realizes low voltage drive which reducing the size of the pressure chamber. All the grooves serve as pressure chambers without any slit or similar wasteful space intervening between them. This implements a multinozzle print head having a dense configuration. With such a print head, the recording device achieves a miniature and compact arrangement.

Patent CA-2194846-A1 (CA)
Title: System and method for the efficient control of a radio communications network
Inventor: FULTHORP RICHARD J
IPC: H04B7/185
Filed: 1997-01-10
Abstract: A means of optimizing throughput on a communications channel shared by multiple users. A communications channel that must be shared by a large number of devices has the potential of being very inefficient because of collisions or overlapping of transmissions by the various devices. The system combines a carrier sense, multiple access (CSMA) mode with a time division multiple access (TDMA) mode to achieve a channel utilization greater than 90 percent. The remote units send a poll request to a base station using the CSMA mode and receive a poll signal from the base station with a poll sequence. The remote units send their data in their assigned time slot. The remote units do not have to all be in radio contact with each other to maintain synchronization. Each remote unit selects the base station that it wishes to communicate with based on signal strength of various base stations. The remote units may switch from one base station to another by addressing the selected base station and using the selected base station's synchronization data pattern in radio transmissions from the remote unit. The synchronization data pattern may be different for each base station or may be identical for groups of base stations to provide broader regional control of the communications network. The base station will only communicate with remote units using the synchronization code for that base station. The system also recovers data from a more powerful signal that collides with a weaker signal by examining the received data for the synchronization code from the morepowerful signal.

Title: Cleaning of hollow fibre membranes
Inventor: BECK THOMAS WILLIAM
IPC: B01D63/02
Filed: 1995-09-08
Abstract: A method and apparatus for recovering fine solids from a liquid feed suspension is disclosed. The apparatus has an operating cycle including a concentration part of the cycle in which solids present in the feed suspension are concentrated and a backwash part of the cycle in which supply of feed suspension to the concentrator is interrupted, the concentrator comprises a shell (11), and a plurality of elastic, hollow, microporous, polymer fibres (12) being fixed at their ends within the shell (11). Pressurized feed suspension is supplied to the outside of the fibres curing said concentration part of the cycle and the filtrate may be withdrawn from the fibre lumens during the operating cycle. Tyuring the backwash cycle the concentration part of the cycle is terminated by ceasing supply of feed to said exterior surface of the fibres (12). The shell (11) is then sealed and the remaining filtrate removed from the lumens. A source of fluid under pressure is then applied to said lumens before, at the same time as, or just after opening the shell (11) to atmosphere, to cause explosive decompression through the walls of the fibres (12) whereby the fluid under pressure passes through said walls. The pressure level in said lumens is maintained at a predetermined value for a sufficient time following said decompression to cause substantial portions of solids lodged within and/or on the fibre walls to be dislodged. The dislodged contaminant matter is then washed away by the application of a flow of liquid over the surface of the fibre walls; and the concentration part of the operating cycle is recommenced by introducing the supply of feed suspension to said exterior surface of said fibres (12).
