A method and system are provided for configuring a variable direction of view endoscope generally comprising a graphical user interface and an endoscope having a view controlling device for moving the view vector between predefined, discrete view vector positions. The graphical user interface displays a set of these view vector positions, and the view vector is moved from one of these positions directly to another in response to a command from a user via the graphical user interface.

A foldable table includes a seat secured to a chair, a shaft pivotally secured to the seat at a pivot axle and rotatable from a horizontal position to a vertical position, and a board pivotally secured to the shaft at a pivot pin and rotatable relative to the shaft to a horizontal working position. A casing is secured to the board and includes a hub for rotatably receiving the shaft. A plate is secured to the casing and has a curved slot for receiving a fastener extended from the shaft and for l...

A method of manufacturing an electronic device using boron nitrides comprises the steps of adding impurities in boron nitrides by ion implantation to form a doped region and directing a laser beam onto the doped region while the boron nitrides are placed in a vacuum or a non-oxidizing atmosphere.

A traverse head for a rotary drill rig includes a motor and gearcase supported by and drivably connected to a rotatable shaft disposed on a frame. The shaft includes a pair of spaced apart pinions drivably engaged with a pair of parallel gear racks mounted on an elongated mast whereby the traverse head may be driven along the mast to perform pulldown and hoisting movements on a drill stem. The traverse head includes a motor and gear housing mounted on the frame and connected to the drill stem. T...

An arrangement for adding together two n-digit decimal numbers or subtracting one n-digit decimal number from another comprises 10-condition switch means, the 10 conditions corresponding respectively to digits in the range 0 to 9 to be added or subtracted, and means to determine the need for and to implement the necessary carries.

A chain-drive cargo-handling system within the cargo deck of an aircraft in the form of a conveyor mechanism involving an endless chain assembly continuously operated by a suitable motor. The chain comprises a plurality of interconnected rollers with support pads which are raised by inflatable tubes positioned thereunder to cause uniform frictional pressure contact to the bottom surface of cargo pallets to be moved on support rollers from station to station on the cargo deck. The frictional enga...

A mast mounted percussion rock drill having a force transmitting frame which provides for a feed force to be exerted on the drill and drill string in a direction which is coaxial with the longitudinal axis of the drill string. The force transmitting frame is adapted to be slidably retained in a mast structure having spaced inwardly facing channel members. The force transmitting frame is attached to a single feed chain centrally located on the drill mast and includes a hydraulic force sensor for ...

A ball cock has a housing that includes at least two housing parts. Each part has a flow-through channel as a flow-through path. The ball cock also includes a ball-shaped shut-off element having a passage bore as a flow path for optionally connecting the flow-through paths of the housing parts. This shut-off element is accommodated within the housing between ring-shaped seals, and can be switched by means of a switching shaft between an open position in which the flow path is released and a clos...

A method and system for clamping a part in an automated tool to produce the part includes selecting a part for production on an automated tool driving a cutter. Deriving a clamping scenario defines the positioning of a plurality of clamps to fix the part to the automated tool. Generating a numeric controlled cutting program is based upon the part and the clamping scenario. Simulating the running of the numeric controlled program predicts interferences between the cutter and any of the plurality ...

A rotation detection sensor, which is a wheel-speed sensor, has a detection unit placed in a metal capped cylindrical casing and a holder fit in an opening of the casing. A flange is provided along the entire edge of the opening of the casing. Between the flange and the holder, a viscoelastic liquid gasket is entirely applied. The edge of the opening of the casing and the exposed part of the holder are covered with a resin portion. Thus, the viscoelastic liquid gasket smoothly enters the gap bet...
