Title: Method of conditioning inter-pixel gaps in a ferroelectric liquid crystal display device
Inventor: YEOH COLIN T H
IPC: G02F1/133
Filed: 1993-05-14
Abstract: In a ferroelectric liquid crystal display (1) the inter-pixel gaps are conditioned to improve the contrast of the display by applying a voltage (11, 13, 17) of such magnitude, polarity and duration to the display as to set all inter-pixel gaps in a predetermined state without altering the initial alignment of the pixels.

Patent CA-2123520-A1 (CA)
Inventor: AUBIN JOSEPH J
IPC: F16H1/32
Filed: 1994-05-13
Abstract: Abstract of the Disclosure The present invention comprises an extended tooth contact harmonic drive gearing apparatus for transmitting rotary motion from an input drive to an output drive through mating contact between a flexspline and a rigid circular spline, the flexspline being swept into a non-circular shape by a wave generator.  The wave generator causes the teeth of the flexspline to precess from a normal to an inclined orientation and back to a normal orientation again. The teeth on both the flexspline and the circular spline have a profile which accomodates that tooth inclination, and thus avoids interference therebetween.

Abstract: The invention relates to a multiplexes for a digital switch, arranged to be included in a switch network whose data flow is organised in frames containing a number of time slots, said time slots including data time slots, which shall be directed through the switch from first to second sets of terminal units, such as subscriber connections, trunk connections, processors, etc. The multiplexes is controlled by a processor for controllable multiplexing, i.e. mapping, of a number of transmission links from each of a corresponding number of the terminal units of said first set to a transmission link leading to the switch, as well as of a transmission link leading from the switch to a number of transmission links leading to each of a corresponding number of terminal units of said second set. The mapping is performed on the data time slots. All data time slots arriving from the terminal units of said first set are to be sent forward via first buffer means to the switch in an order which is determined by a first control memory for the mapping, and all data time slots arriving from the switch are to be sent forward via second buffer means toward the terminal units of said second set in an order which is determined by a second control memory for the mapping. Said buffer means are implemented as fifos, one for each of the links from and to the terminal units.

Title: Apparatus for, and method of, maintaining a clean window in a laser
Inventor: AKINS ROBERT P
IPC: H01S3/034
Filed: 1993-10-25
Abstract: A first gas in a laser cavity is ionized by an electrical discharge in the cavity as a step in producing an energy radiation. Debris (particulates) is produced during the formation of the energy radiation. The radiation and the debris move toward an optical element in the cavity. The optical element may be a window or a mirror. The debris tends to deposit everywhere in the cavity, including on the optical element, thereby dirtying the optical element. This inhibits the efficiency in the laser operation. A clean gas is directed into the cavity through a passage at a position displaced from the optical element. The clean gas then passes in the cavity through an orifice further from the optical element than the passage. The flow of the first gas through the orifice creates a venturi effect on the clean gas to insure than the clean gas will move away from the optical element. In this way, the clean gas inhibits the first gas and the debris from moving to the optical element. Baffles in the cavity between the passage and the orifice provide irregularities in the movement of the first gas from the orifice to the optical element, thereby further inhibiting the movement of the debris to the optical element. Baffles in the cavity between the passage and the optical element also inhibit the movement of any gas to the optical element.    An electrically grounded screen in the displaced passage attracts any ions present in the clean gas.
