Patent CA-2009001-A1 (CA)
Inventor: SCHAUDER COLIN D
IPC: B66B5/10
Filed: 1990-01-31
Abstract: A feedback controlled elevator system driven by a traction drive motor in response to a speed pattern provided by a car controller. The speed pattern is limited when the car approaches a terminal floor within a predetermined terminal slowdown zone adjacent to the terminal floor. A pattern limiting signal is provided in response to digital integration of shaft encoder signals which provides a digital position "x" of the car within a terminal zone. The position "x" of the car is then used to access a read-only-memory which contains the maximum car speed for the specific location of the elevator car. The value from the read-only memory is used to limit the speed pattern.

Title: Trench jfet integrated circuit elements
Inventor: SOLOMON ALLEN L
IPC: H01L27/098
Filed: 1990-02-01
Abstract: A method and construction are disclosed to form a trench gate JFET transistor.   The invention comprises forming a first trench in a semiconductor substrate, forming a gate channel about the trench and forming a conductive layer upon the surface of the gate channel. The conductive layer interfaces with the gate channel to form a p-n junction.  Source and drain regions are formed adjacent to a trench and disposed in electrical contact with the gate channel.   An integral capacitor may be added to the construction by forming a second trench, which extends through and excavates a portion of the first trench.   The drain region is extended about the surface of the second trench to remain in electrical contact with the gate channel.   A layer of insulating material is applied to the second trench, which is then filled  with  a  body  of  conductive  material.  The conductive material is insulated from the conductive layer by the insulating layer.

Abstract: HOLLOW CONNECTING ROD                          ABSTRACT           A precision cast connecting rod which has an elongate tubular shank member defining a hollow section for producing desired stiffness to weight characteristics.    Piston  and  crankpin  connecting members are attached to opposite ends of the shank member.   The connecting members are provided with passages which extend axially therewithin from the hollow section.  Defined within the elongate tubular shank member is a radially extending central aperture. A precision casting method for preparing the hollow connecting rod includes forming an elongate core with a locating member positioned at each end thereof and a   disk-shaped  protuberance   extending   radially therefrom.  The core is secured in a die and defines a cavity therebetween for preparing a pattern of the connecting  rod  using  a  molding material  which substantially encapsulates the core within the cavity. After removing the pattern from the die, coatings of refractory material are applied to form a shell mold which encrusts the pattern.  Removal of the molding material results from heating the shell mold.   The connecting rod is formed by filling the cavity with molten  metal  and  then  cooling  the  shell  mold. Unwanted material is eliminated from the connecting rod by separating the shell mold from the solidified metal and removing the core from the hollow section, thereby producing a near net shape of the connecting rod.

Abstract: DEHUMIFIFIER FOR WAVEGUIDE SYSTEM                 ABSTRACT OF THE DISCLOSURE      A dehumidifying system uses a membrane cartridge to filter water vapor from air or other gas introduced into the membrane cartridge via a main pump or compressor.          Dehumidified gas from the membrane cartridge is then delivered into a system which requires dry gas.  The dehumidifying system further includes valve arrangements or additional compressors which provide gas flow through the membrane cartridge when the main compressor is inactive. Therefore, the membrane cartridge receives a substantially continuous flow of gas which maintains the optimal efficiency of the membrane cartridge.  In addition to the arrangements which provide this continuous gas flow, a heating coil wrapped around the membrane cartridge raises the temperature of the fiber membranes within the cartridge.  The heated fiber membranes are less susceptible to retain moisture which decreases the efficiency of the membrane cartridge.

Abstract: ANTI-DECOUPLING DEVICE FOR ELECTRICAL CONDUIT CONNECTORS            Abstract of the Invention:         An assembly which prevents a nut carried by an electrical conduit from decoupling from a connector.  The inner periphery of the nut near the rear end teeth which define a pair of surface portions between each pair of adjacent teeth.  An adapter has a spring biased detent adapted to be received in the space between an adjacent pair of teeth or in engagement with one of the surface portions.  The first surface portion of each pair of teeth extends at a relatively steep angle away from the inner periphery of the nut, and a second surface portion extends at a relatively shallow angle away from such inner periphery.  When each detent is in a first position adjacent to the steep surface portions, a relatively large force is required to rotate the nut in one direction past the adjacent tooth against the bias force of the spring urging the detent into the respective space; whereas, a relatively small force is required to rotate the nut in the opposite direction as the detent is moved from the first position, at which it is normally located, past the adjacent shallow surface portion and past the next adjacent tooth.  The rotation of the nut in one direction corresponds to the loosening of the nut, and the rotation of the nut in the opposite direction corresponds to the tightening of the nut.

Abstract: A method and apparatus for electronically determining when a ribbon cassette in a printer should be replaced.  The ribbon cassette comprises a housing and an electrically conductive ink ribbon stored in the housing.  The apparatus comprises a detection apparatus which includes a first conductor and a second conductor which pass through the housing and contact the ink ribbon, thereby enabling a signal to be generated when the electrical resistance of the ink ribbon equals a predetermined resistance.  A controller coupled to the detection apparatus causes a message that the ribbon cassette needs to be replaced to be displayed on a display in response to the signal.  The method entails generating a first signal corresponding to the electrical resistance of at least a portion of the ink ribbon; and then generating a second signal when the first signal equals a third signal corresponding to the predetermined resistance of the ink ribbon.
