Title: Water inlet nozzle
Inventor: WILSON STEVEN R
IPC: D06F39/08
Filed: 1990-12-31
Granted: 1996-12-17
Abstract: A water inlet nozzle is mounted to a clothes washer so that water exiting therefrom during the spray rinse cycle is directed onto a load of clothes which has circumferentially accumulated near the bottom of the wash basket during the drain and spin cycle. The water inlet nozzle has an upper member joined to a lower member which forms a dispersion chamber therebetween. The lower member includes an inclined bottom wall which tends to cause water flowing into the inlet nozzle to disperse laterally. The lower member also includes a cascade portion which is curved downwardly and has a transversely convex crown formed within its radius of curvature which induces some water to flow toward the lateral side walls of the lower member. The upper member has a curved forward wall and a front lip which is angled downwardly and rearwardly. A discharge orifice is formed between the terminal edges of the cascade portion and the front lip which is narrower near its center than it is at its edges. The front lip has a radius of curvature formed therein which is larger near the front lip's center than it is near its edges so that water exiting near the edges of the discharge orifice is directed more rearwardly than the water exiting near the center of the discharge orifice thereby forming an arcuate spray pattern. The edges of the spray pattern are directed higher upon the load of clothes in the wash basket than the center of the spray pattern which assures that the clothes are rinsed as thoroughly as practically possible during the spray rinse cycle.

Title: Optical interferometric gyro having reduced light to the light source
Inventor: ASAMI EIICHI
IPC: G01C19/72
Filed: 1991-08-29
Granted: 1996-02-13
Abstract: The present invention relates to an optical interferometric gyro having reduced return light to the light source.  The gyro is configured such that light from a light source is split by a first optical coupler into two light beams.  One of the light beams is further split by a second optical coupler into two beams.  One of the second mentioned light beams is provided as a clockwise light beam to one end of a looped optical transmission line, and the other light beam is provided as a counterclockwise light beam to the other end of the looped optical transmission line.  The clockwise and counterclockwise light beams after having been passed through the looped optical transmission line are combined by the second optical coupler to interfere with each other.  The interference light is branched by the firs optical coupler to the light source and a photodetector, and an angular velocity applied to the looped optical transmission line about its axis is detected from the output of the photodetector.  The branching ratio of the first optical coupler is selected such that the quantity of light to be branched to the photodetector is larger than the quantity of light to be branched to the light source.

Granted: 1998-10-13
Abstract: A television apparatus includes a kinescope having a high voltage supply, a deflection circuit, a cathode driver amplifier and a control circuit for controlling operating modes of the receiver. A first means responsive to a turn-off command signal from the control circuit disables the high voltage supply and initiates turn off of the deflection circuit at a controlled rate. Concurrently, a second means responsive to the turn-off command applies a turn on drive signal to at least one electron gun of said kinescope for discharging high voltage therefrom. Advantageously, during turn-off the high voltage is drained from the kinescope as the displayed raster collapses thus providing benefits such as (1) the safety feature of having a fully discharged kinescope, (2) avoidance of kinescope spot burn and (3) prevention of kinescope after-glow.

Abstract: A fibre-optic gyroscope is provided herein for measuring an angular velocity of a fibre coil by propagating light beams clockwise and counterclockwise in a specified fibre coil, by detecting an intensity of an interference beam, and calculating a phase difference between a clockwise propagated beam and a counterclockwise propagated beam. The fibre-optic gyroscope includes a light source for emitting a quasi-monochromatic light beam. A photodetector is provided for detecting an intensity of the interference beam. A defined plurality of fibre paths are interconnected in a specific defined manner, with a polarizer, a first depolarizer and a second depolarizer as well as a first coupler and a second coupler being provided in specified fibre paths. The depolarizers are constructed by coupling a polarization-maintaining fibre to the front end and/or the rear end of the polarizer at a 45° inclin-ation angle between principal axes of the polarizer and the polarization-maintaining fibre. The polarization-maintaining fibre has a difference of optical paths between the quasi-monochromatic beam and the interference beam with different principal axes being longer than a coherent length of the light source.
