Patent CA-2294291-A1 (CA)
Inventor: IIJIMA YUKIKO
IPC: H01M10/052
Filed: 1999-04-22
Abstract: A solid-electrolyte secondary battery is provided which comprises a positive electrode, negative electrode and a solid electrolyte provided between the electrodes. The solid electrolyte contains as a matrix polymer a fluorocarbon polymer of 550,000 in weight-average molecular weight (Mw). The fluorocarbon polymer having a weight-average molecular weight of more than 550,000 shows an excellent adhesion to the active material layers of the positive and negative layers. Therefore, the high polymer solid (or gel) electrolyte adheres to the active material layers of the electrodes with a sufficient adhesive strength. A  fluorocarbon polymer having a weight-average molecular weight (Mw) over 300,000 and under 550,000 may be used in combination with a fluorocarbon polymer of 550,000 or more in weight-average molecular weight to lower the viscosity for facilitating the formation of a film of the electrolyte.

Title: Dynamically adjustable high resolution adjustable slit
Inventor: MCCULLOUGH ANDREW W
IPC: G03F7/23
Filed: 2000-01-06
Abstract: Blades (48) pivotally attached together linked to push rods (34) and inserted into an illumination field, energy or flux (510). The blades (48; 520) extend longitudinally along the length of a rectangular illumination field or slit (510) used to image a reticle (537) onto a photosensitive substrate. The blades (48; 520) controllably adjust the width of the rectangular illumination field (510) to modify the illumination intensity or energy provided to a photosensitive substrate. The illumination field (510) is scanned across the photosensitive substrate (560) to expose it with the image of a reticle (537). The blades (48; 520) are dynamically controlled (541) during the scanning exposure to adjust the illumination intensity or energy in a predetermined way. The resulting selective change in exposure dose corrects local area of line width variance. Various errors in pattern reproduction using a photolithographic system are relatively easily corrected. This is particularly advantageous in a scanning lithography system used in the manufacture of semiconductors.

Patent CA-2297835-A1 (CA)
Inventor: COMTE CHRISTOPHE
IPC: G01R31/36
Filed: 1998-07-23
Abstract: A distributed battery system includes a number of energy storing modules, each of which includes a processor and communications interface. In a network mode of operation, a battery computer communicates with each of the module processors over an intra-battery network and cooperates with individual module processors to coordinate module monitoring and control operations. The battery computer monitors a number of battery and module conditions, including the potential and current state of the battery and individual modules, and the conditions of the battery's thermal management system. A module transitions to a stand-alone mode of operation if the module detects an absence of communication connectivity with the battery computer. The module processor autonomously coordinates monitoring of current, potential, and temperature conditions, effects bypassing of defective cells, equalizes cell voltages during charge and discharge cycles, and detects and logs fault conditions arising in the module.

Title: Method and system for detecting the state of dialling a codenumber
Inventor: HANSEN FLEMMING
IPC: H04Q3/78
Filed: 1998-07-30
Abstract: In a method for detecting the state of dialling a codenumber a number of already dialled digits (Nx) is counted and is compared with a defined number of digits to be dialled. If this number is reached, a timer (Tx) is started and during the runtime of the timer it is detected whether further digits are dialled. If further digits are dialled the timer is restated at every detection. If no further digit is detected, after time out of the timer a query is launched. Alternatively after launching a first query it is possible to analyse the already dialled number of digits and to define a number of digits to be dialled. If then this number is reached, a timer is started and the further method is processed.

Patent CA-2303637-A1 (CA)
Title: Label adhesive with dispersed refractive particles
Inventor: KILLEY EDWARD J
IPC: C09J11/08
Filed: 2000-03-31
Abstract: A pressure sensitive adhesive composition comprised of a substantially tacky polymer containing a number of prismatic or holographic platelets. When the composition is applied to a substrate, the platelets align themselves in a planar fashion parallel to the broad face of the surface on which the coating is applied. The resulting composition layer is transparent except for the platelets that refract and reflect the light striking the platelets back towards an observer. The color of the reflected light changes as the angle at which the platelets are viewed is changed. In this manner, the platelets in the coating provide an overall aesthetically pleasing appearance for the coated material that adds distinctiveness to decorative labeling, as well as to the objects on which the labeling is placed and other suitable types of laminations in which the adhesive coating may be used. Furthermore, the labeling may be used as an indication of counterfeit objects or of tampering with the object on which the labeling is placed because the platelets will either not be in an aligned position, or will shift from their aligned position within the adhesive composition when the labeling is disturbed.

A reversing lever (18) is coupled to the ratchet mechanism (25, 26) and is movable to forward, non-ratcheting and reverse positions to select a ratchet direction. The direction control element (18) carries a protruding element (20) that is shaped to fit into a recess (6) in the tool release actuator (3) when the direction control element (18) is in the forward position, to remain outside the recess (6) when the direction control element (18) is in the non-ratcheting position, and to fit into the recess (18) when the direction control element is in the reverse position. The protruding element (20) impedes inadvertent operation of the tool release mechanism (2, 3, 5, 12) when the direction control mechanism (18) is in either the forward or the reverse positions.

IPC: G01N21/35
Filed: 1998-12-04
Abstract: An improved gas detector apparatus (100) includes a spectral source/bolometer (102) for conducting an electrical current and for producing infrared radiation. The source/bolometer has a characteristic resistance that is a predetermined function of the source/bolometer temperature.

A driver/detector (110) drives a current through the source/bolometer, determines the characteristic resistance of the source/bolometer, and detects the gas from a variation of the characteristic resistance.
