Patent CA-2143293-A1 (CA)
Title: Electronic component
Inventor: ISHIHARA SUSUMU
IPC: H05K3/30
Filed: 1993-07-05
Abstract: An electronic element A1 has a lead electrode at the edge and a supporting member A2, positioned so that it faces the electronic element across a gap G. The supporting member A2 also has an external connecting terminal A5 at a location opposite the lead electrode A4. A resin layer A3 is positioned between electronic element A1 and supporting member A2, indented by the distance d from the edge of the electronic element A1. The resin layer bonds the electronic element (A1) and supporting member A2. The relationship of the distance d with G should satisfy this expression; d > G. A solder A6 fills the space created by the gap G between the lead electrode A4 and the external connecting terminal A5 over the distance d which is the distance from the edge of the electronic component A1, to the resin layer A3. The solder connects the lead electrode A4 and the external connecting terminal A5. No defective connection occurs between the lead electrode and the external connecting terminal when the electronic component is mounted on the printed board.

Title: Water quality monitor for a water purification system
Inventor: BURROWS BRUCE D
IPC: G05D21/02
Filed: 1995-02-27
Abstract: An improved water quality monitor is provided for use in a water purification system of the type having a reverse osmosis unit for producing relatively pure water from a tap water supply. The reverse osmosis unit supplies produced purified water to a reservoir for storage until dispensing, as by opening a faucet valve. An inlet shut-off valve closes to prevent tap water inflow to the reverse osmosis unit when the reservoir reaches a substantially filled condition. The water quality monitor includes electrodes in contact with the tap water and the produced purified water to obtain comparative conductivity readings which represent the performance level of the reverse osmosis unit in removing impurities from the tap water inflow. The monitor includes a test circuit responsive to movement of the inlet shut-off valve to take a conductivity reading at a point in time substantially after the shut-off valve, opens to resume tap water inflow to the reverse osmosis unit, and substantially prior to shut-off valve closure when the reservoir reaches the filled condition. This conductivity reading is stored in memory for subsequent periodic display, for example, each time the faucet valve is opened, by energization of one or more indicator lights.

Patent CA-2151839-A1 (CA)
Title: Electronic engine timing
Inventor: IMBERG HANS
IPC: F02D41/34
Filed: 1993-12-14
Abstract: An electronic  timing system for producing precise timing control signals to the fuel injectors and ignition coils  of  an  internal  combustion engine.    The  system includes a means for generating an engine cycle reference signal based on the detected operational position of the engine as indicated by a TDC signal and a fly wheel teeth (FWT)  signal.    The  system also  includes  a means  for controlling  the  sequence  of  combustion  in  respective cylinders of the engine responsive to the engine cycle reference signal.  A multiplying circuit in the form of a phase lock loop (PLL) circuit is provided for multiplying the incoming FWT signal to produce a high resolution engine rotation signal which is a programmable integer multiple of the FWT signal.   Injector and ignition timing control signals can be delayed by timers with a programmable delay specified in terms of an integer multiple of the multiplied FWT signal, and can therefore be precisely set in terms of crank angle before TDC regardless of the engine speed. Furthermore, being angle referenced each programmable delay at least maintains the last calculated advance setting regardless of changes in engine speed.

Title: Naphthalene alkylation with partial rare earth exchanged catalyst
Inventor: ARDITO SUSAN CHMURA
IPC: C07C2/86
Filed: 1994-12-09
Abstract: Long chain alkyl substituted naphthalenes are produced by the alkylation of naphthalene with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite having rare earths associated with less than 50 % of the exchangeable sites of the zeolite.
