Title: Superconducting device having an extremely thin superconducting channel formed of oxide superconductor material and method for manufacturing the same
Inventor: INADA HIROSHI
IPC: H01L39/14
Filed: 1991-11-01
Granted: 1996-08-06
Abstract: A superconducting device comprises a substrate, an extremely thin superconducting channel formed of an oxide superconductor on the principal surface of said substrate. A superconducting source electrode and a superconducting drain electrode of a relatively thick thickness is formed of the oxide superconductor on said superconducting channel separated  from each other but  electrically connected by said superconducting channel, so that a superconducting current can flow through said superconducting channel between the superconducting source electrode and the superconducting drain electrode.  A superconducting gate electrode is formed of the oxide superconductor through a gate insulator on said superconducting channel for controlling the superconducting current flowing through said superconducting channel. And a side insulating region is formed to completely cover each of opposite side surfaces of the superconducting gate electrode. The superconducting channel and the gate insulator are formed of the same oxide thin film of which oxygen amount is locally decreased and said gate insulator being formed of a compound oxide which is composed of the same constituent elements as those of the oxide superconductor of which the superconducting channel is formed but includes the oxygen amount less than that of said oxide superconductor. And the superconducting gate electrode is surrounded by the superconducting channel, the superconducting source electrode and the superconducting drain electrode but electrically isolated from the superconducting channel, the superconducting source electrode and the superconducting drain electrode by the gate insulator and the side insulating region.

Title: Reactive power compensator
Inventor: EL-SHARKAWI MOHAMED A
IPC: H02J3/18
Filed: 1992-03-05
Granted: 1996-11-05
Abstract: A system and method for determining and providing reactive power compensation for an inductive load. A reactive power compensator (50,50') monitors the voltage and current flowing through each of three distribution lines (52a,52b,52c), which are supplying three-phase power to one or more inductive loads. Using signals indicative of the current on each of these lines when the voltage waveform on the line crosses zero, the reactive power compensator determines a reactive power compensation capacitance that must be connected to the lines to maintain a desired VAR level, power factor, or line voltage. Alternatively, an operator can manually select a specific capacitance for connection to each line, or the capacitance can be selected based on a time schedule. The reactive power compensator produces control signals, which are coupled through optical fibers (102/106) to a switch driver (110,110') to selectspecific compensation capacitors (112) for connections to each line. The switch driver develops triggering signals that are supplied to a plurality of series-connected solid state switches (350), which control charge current in onedirection in respect to ground for each compensation capacitor. During each cycle, current flows from ground to charge the capacitors as the voltage on the line begins to go negative from its positive peak value. The triggering signals are applied to gate the solid state switches into a conducting state when the potential on the lines and on the capacitors reaches a negative peak value, thereby minimizing both the potential difference and across the charge current through the switches when they begin to conduct. Any harmonic distortion on the potential and current carried by the lines is filtered out from the current and potential signals used by the reactive power compensator so that it does not affect the determination of the required reactive compensation.

Title: Cervical videoscope with detachable camera unit
Inventor: ADAIR EDWIN L
IPC: A61B18/24
Filed: 1992-04-14
Granted: 2001-07-03
Abstract: A simple yet highly useful cervical videoscope has been provided which can easily be used by the doctor to examine the cervix and vagina far cancerous lesions or other abnormalities. Also, because of the small size of the video camera unit there is sufficient space between the video camera unit and the blades of the speculum for inserting forceps and other instruments that may need to be used. By using the cervical videoscope in combination with a monochromator the physician can step the wavelength of light from one end of the light spectrum to the other until he observes florescence which identifies abnormal cells. Thereupon, he can destroy the cells by use of a laser beam. When he observes that no more florescence is occurring, then he can discontinue the operation of the laser, knowing that the lesion has been completely eradicated. Also, a channel for drawing a suction to remove smoke created by the destruction of the lesion can be provided. The video camera unit also is adjustable along a guide on the fixed blade of the speculum to focus it. The video camera unit can be removed from the speculum and inserted into a sterile sheath for reinsertion into the vagina for examination for lesions and areas covered by the speculum blade. It can also be inserted into the colon and other body passageways where lesions are suspected. The video camera unit can be removed from the sheath, resterilized or disinfected and reattached to a sterile speculum for use with another patient.

Granted: 1999-01-05
Abstract: A method and apparatus is provided for controlling the speed of a slave drive roller in a coating machine. Speed of the slave drive roller at a second coater is regulated by an adaptive gain allowing greater tolerances when not at run speed.  That is, in addition to normal speed correction, the system accommodates greater web speed fluctuation during threadup,  acceleration,  and deceleration.   This accommodation may be based on the sensed position of the float roller or, alternatively, on the sensed rate of acceleration/deceleration of the master drive roller.

Abstract: Telephone headsets used by operators and airline pilot headsets are subject to substantial amounts of interfering ambient noise which detract from the intelligibility of incoming speech.  Noise reduction circuitry does not altogether eliminate the interfering sound.  A headset speaker and error microphone housing are disclosed which enable a greater amount of unwanted noise elimination.  The speaker and microphone are configured closely with respect to each other and also to the user's ear.  They are acoustically isolated in their own chamber.  The microphone is located approximately on the speaker axis and protrudes substantially into the user's ear; and also is disposed close to the speaker cone surface.  Additional acoustical tuning features include venting ports in the housing, and acoustic damping padding at the microphone entrance and on either side of the speaker.  These expedients enhance the ability of the noise-cancelling circuitry to effectively reduce the undesired noise heard by the user.

Granted: 2002-10-01
Abstract: In this tiltable supporting roller bearing according to the invention for supporting a rotary drum there are provided a freely rotatably mounted supporting roller and an appertaining bearing structure which is tiltably supported with respect to a stationary foundation plate with the aid of easily shifted support bearings which are arranged inclined against one another in such a way that the point of rotation of the line of contact between the supporting roller and the riding ring of the rotary drum lies with the vertical central axis of the supporting roller. With a particularly simple and reliable design, this construction makes it possible to compensate for skewing of the rotary drum riding ring and at the same time markedly to reduce or largely avoid undesirable consequences of the axial forces resulting from longitudinal movements of the rotary drum. In a first embodiment two supporting rollers with their bearing structures are combined to form a supporting roller set. The two bearing structures are connected to one another by at least one spacer element in order to maintain a constant spacing. In another embodiment, there is a stationary support element, to which each of the two bearing structures is connected by a spacer element.
