Title: Active rf cavity
Inventor: CHEO BERNARD R
IPC: H03F3/60
Filed: 1993-12-22
Abstract: An active RF cavity is defined by a conductive wall in which a plurality of stolid state power amplifiers are mounted. The solid state power amplifiers induce an RF current at an inner surface of the wall to form an oscillating electromagnetic (EM) field within the cavity.      Preferably, the power amplifiers are in tha form of modules that contain a number of RF power chips. The structure operates as both a power combiner and a matching transformer and is powered by a relatively low voltage d.c. source. A high-amplitude field is generated using equipment that is more efficient and much lighter in weight than conventional equipment. Such a cavity may be applied in a drift tube linac, an RF quadrupole linac, a linac having aligned cavities, and in other types of particle accelerators, and as a high power RF amplifier with the EM waves piped out via a waveguide or a coaxial cable.

Title: Esd input protection arrangement
Inventor: ORCHARD-WEBB JONATHAN H
IPC: H01L27/02
Filed: 1994-02-11
Abstract: An arrangement for protecting an input of a monolithic integrated circuit against ESD events, comprises a thick field bipolar main transistor adapted to breakdown under ESD stress to dissipate ESD energy, a thin field bipolar main transistor adapted to breakdown under ESD stress, and an attenuator resistor.  The thin field transistor has a lower breakdown voltage than the thick field transistor whereby for an ESD event of a given polarity, the thin field transistor breaks down before the thick field transistor. During an ESD event current, the thin field device responds rapidly to the fast edge of an ESD transient and thereby shunts current that the thick field device is too slow to respond to.

Title: System for continuously monitoring curing energy levels within a curing unit
Inventor: MOORE ROBERT C
IPC: G02B6/44
Filed: 1994-02-14
Abstract: System For Continuously Monitoring Curing Energy Levels Within A Curing Unit Abstract The present invention continuously monitors the amount of curing radiation available for curing coating material on a moving optical fiber and includes a curing system having a radiation source capable of providing radiation energy for curing coating material on an optical fiber and a reflector system which redirects non-direct radiation back toward the article. An optical fiber which has been provided with a curable coating material is moved along a path of travel a curing area. The coating material is cured by causing the radiation source to emit energy suitable for curing the curable coating material. The predictable average amount of light energy properly redirected by the reflector system toward the curable article is sensed as the curable coating material is being cured to obtain continuous in-process reading. The average radiation value is obtained by positioning three longitudinally aligned holes adjacent the fiber path and between the fiber and a radiation sensing device. Furthermore, the amount of the light energy available from the reflector system may be sensed at a location which is outside the reflector system to obtain a reference reading. The in-process readings may then be compared with the reference reading to determine the portion of the radiation available from the radiation source which is actually available for curing the curable coating material.

IPC: A01M1/04
Filed: 1994-03-25
Abstract: An insect trap using attractant light, comprising a source of light and a housing can be mounted on a vertical surface or placed near a ceiling surface. The housing and the source of light cooperate to form an upwardly facing opening for the facilitated entry of flying insect pests and for the reflection of light onto the vertical surface. Insects that enter the trap are immobilized on a surface within the trap. Cooperation between direct radiant light, reflected light and an upwardly facing entrance for insects substantially increase capture rates.
Patent CA-2120261-A1 (CA)
Inventor: MATTHEWS JAMES A
IPC: H01L29/732
Filed: 1992-10-19
Abstract: 2120261 9308599 PCTABS00021 A bipolar transistor having an emitter (25), a base (31), and a collector (30) includes an intrinsic base (33) region having narrow side areas (p-) and a wider central area (37). The side areas are located adjacent to the extrinsic base region (31), while the central area (37) is disposed underneath the emitter (25). The lateral doping profile of the base is tailored so that the doping concentrations in the extrinsic region (31) and the central area (37) are relatively high compared to the doping concentration of the narrow side areas (p-) of the intrinsic base (33). The combination of the narrow side areas (p-) and the lateral base doping profile constrains the depletion region within the base thereby lowering punch-through voltage of the transistor without loss of beta.

Title: Method of regulating a torque transmitting system
Inventor: OTTO DIETER
IPC: F16H59/24
Filed: 1993-08-21
Abstract: A method of operating a torque transmitting system with a hydrodynamic power transmission and with a friction clutch which bridges the power transmission, involves controlling a lock-up clutch and the hydrodynamic power transmission of such system so that clutch slip is present.      The method of operating involves a regulation of torque and includes the breaking up of input torque furnished by a prime mover into a torque which is to be transmitted by the power transmission and a torque which is to be transmitted by the lock-up clutch. The lock-up clutch includes an annular piston which is disposed between the cover of the power transmission and the turbine wheel. The radially outer portion of the piston constitutes a clutch disc and its radially inner. portion is mounted on a complementary sealing hub. The power transmission is "soft" and exhibits a flat progress of the primary characteristic curve as well as a wide secondary characteristic curve, i.e., a wide torque conversion range.

Inventor: BENTZ R DENNIS
IPC: H01M10/42
Filed: 1993-03-12
Abstract: A metal-air power supply which provides improved control over air flow is provided. The reactant air and cooling air inlets are separate from one another and isolated from the exhausted reactant and cooling portions of the air flow. The reactant air flow is limited to a volumetric flow rate sufficient to provide from about 3 to about 10 times the stoichiometric amount of oxygen necessary to produce a predetermined level of current from the cell, and a total volumetric flow rate of air sufficient so that the cooling portion of the air flow has a volumetric flow rate from about 10 to about 1000 times the volumetric flow rate of the reactant portion of the air flow is provided. This limits the flow rate of the reactant air over the cathode, isolates the cooling air flow from the reactant air flow, and maintains the temperature of the metal-air cell at a low level without exposing the air cathode to an excessive air flow rate to reduce the likelihood of drying out the metal-air cells, reduce the exposure of the battery cell to contaminants, and minimize the effects of temperature on the vaporization of water within the cell. In a preferred embodiment, the power supply housing and the metal-air cell case form part of the air plenums. A substantially leak-proof metal-air cell is also disclosed.

Title: Clamp Control for Injection Molding Machine

IPC: B29C45/78
Filed: 1995-02-17
Abstract: A control system utilizing a programmable controller for an injection molding machine  in which the controller is periodically scanned in response to input signals to produce output control signals is provided with an impulse response filter arrangement.   The impulse response filter senses a plurality of current and past sensor input signals to accu-rately predict the occurrence of a variable triggering event which will in fact be sensed by a sensor.  A predictive sensor signal is then generated which is inputted to the controller in advance of the occurrence of the triggering event and at a time which corresponds to the processor scan time so that the controller generates the desired output at the precise time the  triggering  event  occurs  thus  eliminating  controller response latency from the control system.
