  • Patent number: 6075334
    Abstract: A system for automatically calibrating a semiconductor wafer handling robot so that the robot will move wafers into and out of precise locations within enclosures that form process stations or storage cassettes is disclosed. The system comprises a controller having memory and logic sections connected to a robot having an articulated arm that is movable in vertical (Z), horizontal (.theta.), and radial (R) directions and having a wafer retaining wand at the end of the arm. Dimensional characteristics of the robot wand and the enclosures are stored in the controller memory. Sensors are provided at each enclosure and/or the robot wand which are activated and provide signals to the controller that are relative to the wand position. The robot is programmed to execute a series of progressive movements at each enclosure location which are controlled by a combination of sensor response signals and the appropriate dimensional characteristics.

  • Patent number: 6071145
    Abstract: A protective housing for an elongated metal connector attached to the end of an electrical conductor wherein the connector comprises a tubular portion at its rear end for receiving the conductor and a contact portion at its forward end. The protective housing comprises a bottom section of rigid non-conductive material having a semi-cylindrical portion and a forward tubular portion for holding the metal connector. A top section of the housing fits against and is secured to the semi-cylindrical portion of the bottom section to form the assembled protective housing. Internal members within the top and bottom portions are adapted to engage the outer surface of the metal connector and provide heat insulgating air spaces around the metal connector within the assembled housing.

  • Patent number: 5936913
    Abstract: A receiver section for an acoustic oil well logging tool comprised of a plurality of receiver sub-units connected longitudinally within a rigid tubular member. Each receiver sub-unit has a series of acoustic wave sensors located for receiving and detecting monopole, dipole, quadrupole and unipole waveforms. Separate channels are provided for conveying waveforms data from each receiver sub-unit to an above ground data processing unit. Each receiver sub-unit also includes a compensating sensor for detecting tool vibrations and for producing signals which are combined with waveform data in the processing unit to eliminate the effects of tool vibration.

  • Patent number: 5893360
    Abstract: An inflatable solar oven is comprised of two sheets of flexible material which are sealed at their edges to form an enclosure. The top sheet is clear and the bottom sheet has a reflective layer. The two sheets can be inflated to form a spherical enclosure by passing air through an edge opening that is also large enough to access a water or food holding receptacle which can be placed with the inflated enclosure. Extended portions of the sheets that form the opening can be rolled up to form a closure for it. The inflated enclosure can be secured to the ground in an appropriate position to receive the sun's rays which pass through the clear sheet and reflect from the bottom sheet to heat the receptacle therein.
