Title: A method for controlling coming and going personnel, and a system thereof
Inventor: NISHIKAWA YOSHIHIRO
IPC: E05B65/00
Filed: 2001-08-20
Abstract: The present invention provides a high-level security coming and going personnel control system by prohibiting a coming person who has dealt with a dangerous substance from entering a facility through a control area. Whether a person coming into the control area carries a dangerous substance such as explosive material with him or has dealt with such dangerous substance can be checked by: ionizing air which has been contacted with the person coming into a control area by a discharging device; detecting the ionized air by a mass spectrometer as a molecular weight; inputting the molecular weight into a control processor; and if the detected molecular weight is matched with a molecular weight of a dangerous substance which has been registered previously into the control processor, closing the door in a direction forward to the coming person.
Patent CA-2357430-A1 (CA)
Title: Media improvements to enhance optical auto-focus performance
Inventor: WANG TANGYU
IPC: B41M5/48
Filed: 2001-09-18
Abstract: Multi-layer imaging media having outer layers that are transmissive at the wavelength of an optical auto-focus system present significant difficulty for the auto-focus sensing and servo systems. Multiple reflections are often in-distinguishable resulting in imaging failures. Improved media include an absorber which absorbs light of a wavelength used to control an auto-focus system. This substantially reduces multiple reflections and reduces the likelihood of imaging errors.

Title: Organic composite insulator and method of producing the same
Inventor: YONEMURA TOKUI
IPC: H01B17/26
Filed: 2001-11-19
Abstract: An organic composite insulator (tube) and method for production thereof giving an external flashover characteristic, enabling a reduction of the cost, and enabling a reduction of the size of the insulator. The outside diameters of the insulator sheath body and watersheds at only the intermediate insulator sheath 3c corresponding to the vicinity of the tip 6a of the top of the inside electrode 6 are made larger than the outside diameters of the body and watersheds of the upper and lower insulator sheaths 3a and 3b. The electric field of the sheath surface in the vicinity of the tip 6a of the top of the inside electrode 6 exhibiting the maximum electric field in the large size insulator is weakened and the maximum electric field part is moved to the top portion of the sheath body and watersheds enlarged in inside diameter. Further, the insulator act to block the propagation of the air dielectric breakdown occurring at the maximum electric field part to the ground side end fitting 2' and thereby to increase the external flashover voltage.

Title: Pharmaceutical formulations
Inventor: FANNING NIALL
IPC: A61K39/39
Filed: 2000-08-29
Abstract: The application discloses novel pharmaceutical formulations adapted for delaying the release of a pharmaceutically active agent. A delayed-release drug formulation encapsulates the active ingredient, which may be applied to  microparticles or in tableted form, in a release-delaying coat comprising polymeric materials of predetermined swelling/permeability characteristics. In particular, acrylate and/or acrylic acid polymer blends modified with ionic groups may be used. One preferred embodiment uses a polymer of pH dependent permeability as a more permeable element of the coat. The delayed-release formulations are deployed in a single dosage form together with instant release or sustained release formulations, so that a unit dosage form, preferably an oral dosage form, can effectively administer two doses to a patient at different times.

Title: For stopper gate for product conveyor
Inventor: BREWER MARVIN VINCENT
IPC: G01G13/02
Filed: 2000-10-10
Abstract: A conveyor for distributing food products consisting of a distribution conveyor (100) and a recirculation conveyor (115) where the distribution conveyor (100) has a plurality of slide doors (105) leading to weighing hoppers underneath. A plurality of stopper gates (110), each located downstream of and adjacent to one of the slide doors (105) in the distribution conveyor (100), momentarily holds the food products over the slide doors (105) thereby increasing the likelihood that the product will drop into a weighing hopper rather than recirculate, which helps prevent the food from cooling and becoming stale before it is bagged. Sensing and timing devices, such as level sensors (390), are used to control the actuation of the stopper gates (110) for the most efficient operation.

Abstract: A flowmeter for determining a fluid flow rate on the basis of calibration curves and the output of a sensing circuit comprising a flow rate sensing part including a heater (33) for an indirectly heated flow rate sensor unit and a bridge circuit (73) including sensing elements of a fluid temperature sensing part as constituent resistors. The circuit characteristic value of the bridge circuit (73) are varied in steps by a multiplexer (731) for selectively connecting one of the terminals for connection between resistors connected in series and the output terminal. The number of calibration curves agrees with the number of circuit characteristic values, and one of the calibration curves is selected in accordance with the circuit characteristic value selected by the multiplexer (731). For each calibration curve, a range of flow rate to be measured is determined. A calibration curve is selected in accordance with the range where the measured fluid flow rate lies by controlling the multiplexer (731) according to the measured fluid flow rate. The flowmeter enables measurement of flow rate with good precision in a wide flow rate range.
