Title: Antenna for cordless telephone system
Inventor: ROGERS MAX W
IPC: H04W88/02
Filed: 1989-04-11
Granted: 1992-11-10
Abstract: ABSTRACT OF THE DISCLOSURE            An antenna internally contained within a housing of a cordless telephone is configured generally as a plate disposed opposite the earphone transducer, and away from the user's face in position for normal use.  The antenna is disposed to lie generally vertically, and is counterpoised against a generally vertically disposed circuit board. Configuring the antenna generally as a plate and placing it outboard away from the user's face minimizes detuning effects during normal handling in use.  Optional side extensions to the plate increase the antenna capacitance. An optional counterpoising shield may be interposed between the receiver-transducer and the antenna plate to further minimize detuning effects.  Mode switches are disposed in a position on the handset remote from the antenna to further minimize detuning effects during switching operations.  A similar antenna may be disposed within the cordless telephone base unit with the antenna disposed remote from the surface on which the base unit is mounted, and further having its associated mode switch disposed at a location remote from the antenna so as to minimize detuning effects from proximity to metallic surfaces and mode switching.

Granted: 1994-10-18
Abstract: ABSTRACT OF THE DISCLOSURE      In control cylinder device in a variable displacement compressor, an annular cylinder concentric with the driving rotary shaft is provided in a housing of a compressor body, and annular control piston is slideably fitted in the cylinder to define a control pressure chamber within the cylinder.  The annular control piston is connected to the sleeve, so that the sliding movement of the sleeve can be controlled by the operation of the control piston.  Further, inner and outer seal rings are interposed in an axially misaligned relation to each other between inner and outer slide surfaces of the cylinder and control piston.  This eliminates a high machining accuracy of the inner and outer surfaces of the cylinder in the cylinder device on which the control piston slides.  Also, this easily insures sealing properties required between the slide surfaces of the cylinder and the piston.  In addition, it is possible to effectively prevent the inclination of the control piston within the cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention is an apparatus and method for automatically adjusting the moisture content of feed grains to a relatively constant target level.  As the grain is transported into, or within the feed manufacturing process, a sample is diverted through a continuous flow moisture sensor.  The sensor generates an electronic signal proportional to the moisture content of the grain.  This signal is used to control the application rate of a surfactant - water mixture, or of water alone.          The water may be either in the form of steam or, as a hot or cold liquid.  The grain then enters a mixing or contact chamber, into which the water is metered at a rate that is proportional to the moisture content of the incoming grain.  The treated grain will have a relatively constant moisture content, eliminating one of the largest variables in the manufacturing of livestock feeds.

Abstract: A tripod stand for supporting a musical in-strument or other object, wherein a main post is pro-vided with an upper slide member to which the upper ends of the three legs of the tripod are hingedly con-nected.  A respective articulated arm connects each leg with the lower portion of the main post.  Movement of the slide member up and down causes selective inward and outward movement of the legs.  One of the articu-lated arms is longer than the others and is attached further up its associated leg than the other articulat-ed arms. Consequently, the downward movement of the slide member causes that leg attached to the one arm to move outward further from the main post, making the bottom ends of the legs move from defining an equilat-eral triangle to defining an isosceles triangle and thereby tilting the main post.  Greater stability can be achieved by increasing the angle between the two legs that are opposite the leg having the one longer articulated arm.

Abstract: The preparation of highly densified ceramic bodies by the sintering of certain organopolysiloxanes filled with silicon carbide powders and metal-containing sintering aids is described.  Such highly densified ceramic bodies can be prepared by either a pressureless sintering process or a hot press sintering process.  The compositions of this invention can be formed into desired shapes and then sintered to form ceramic, shaped bodies with high densities.  One advantage of the present invention is that the green bodies have relatively high strengths and thus can be easily handled and, if desired, machined before being sintered.  The organopolysiloxanes useful in this invention must yield a ceramic char which contains free or excess carbon in addition to carbon in the form of silicon carbide upon pyrolysis to elevated temperatures.
