Title: Fibre optical ice detector
Inventor: DJORDJEVICH ALEXANDAR
IPC: G01B11/06
Filed: 1991-08-12
Granted: 1998-12-29
Abstract: This  invention  called  "Fiber  Optical  Ice  Detector"  (FOID) remotely detects early formation of ice around dedicated optical fibers on structure surfaces.  The fibers may be glued to the surface, embedded into it in case of composite materials, or otherwise attached to it.  The invention is based on the light diffusion by ice and light reflection from ice boundaries, that optically couple multimode optical fibres in specially built sensitive zones. Such zones may be multiple in order to achieve sensing distributed along the fibers (rather than at a single location). Sensitive zones consist of specially profiled cross sections that amplify the effects involved by allowing most of the light to be modulated. Thus, the invention makes it possible to achieve early detection of small quantities of ice at multiple locations along the fibers. A most widespread use of this invention is expected in the aircraft industry for remote detection of ice formation around critical parts - wings.

Title: Training device onboard instruction station
Inventor: GLASS RICHARD H
IPC: G09B9/30
Filed: 1991-08-22
Granted: 1997-01-28
Abstract: An onboard instructor station for a training device provides a human/computer interface that is designed to support an optimum instructor's scan pattern of the training scenario.  All displays and switches required to control and monitor the mission are resident at the instructor's work surface directly in front of, and tangent to the instructor's seated position.  This design allows for a dedicated over-the-shoulder observation position.  Therefore, the instructor may simultaneously observe trainees' actions, a visual scene and device instrumentation while controlling and monitoring the training environment through embedded situational awareness displays and corresponding switches at the work surface.  The unique aspect of this design is the one position from which all tasks can be accomplished through the support provided by the packaging.  This packaging employs flat panel displays which replace the traditional, larger CRT units.

Title: Rotary-anode type x-ray tube
Inventor: TAZAWA HIROAKI
IPC: H01J35/10
Filed: 1991-09-30
Granted: 1997-10-07
Abstract: In a rotary-anode type X-ray tube, a rotary-anode is fixed to a cylindrical rotary structure, and a columnar stationary shaft is fitted in the rotary structure.      A gap is formed between the rotary structure and the stationary shaft. The gap is filled with a liquid metal lubricant. Spiral grooves are formed in part of the outer surface of the stationary shaft to form a radial sliding bearing between the stationary shaft and the rotary structure. Spiral grooves are formed in the end faces of the stationary shaft to form a thrust sliding bearing between the stationary shaft and the rotary structure. A recess is formed in the stationary shaft to communicate with gaps in the radial sliding bearing.      A lubricant storage chamber for storing the liquid metal lubricant is formed in the stationary shaft along the center axis. The storage chamber communicates with communicating holes which radially extend to be open to an outer surface region, of the stationary shaft, in which no spiral grooves are formed. With this structure, a sufficient amount of liquid metal lubricant required for a long-term operation of the sliding bearings can be stored in the X-ray tube, thereby maintaining a stable dynamic pressure type sliding bearing operation for a long period of time.

IPC: G01R33/06
Filed: 1994-03-17
Granted: 1998-11-24
Abstract: A Hall-effect device for detecting a magnetic flux intensity has a pair of input terminals connected respectively to a constant-voltage regulated power supply and an FET.  The FET has a gate connected to the output terminal of an operational amplifier.  One of the input terminals of the operational amplifier is connected to the junction between a variable resistor and a temperature-dependent variable resistor which jointly serve as a voltage divider. The temperature-dependent variable resistor has a temperature characteristic of resistance which is opposite to the temperature characteristic of sensitivity of the Hall-effect device.          When the ambient temperature varies, the sensitivity of the Hall-effect device also varies, and so does the resistance of the temperature-dependent variable resistor.  The divided voltage applied from the voltage divider to the operational amplifier drops, lowering the voltage applied to the gate of the FET. The internal resistance of the FET also decreases to lower a drive current flowing through the Hall-effect device for thereby compensating a temperature-dependent sensitivity change of the Hall-effect device.  Therefore, the sensitivity of the Hall-effect device remains constant.
