Granted: 1991-02-19
Abstract: ABSTRACT OF THE DISCLOSURE         A machine tool comprises an upstanding column, a tool-driving unit vertically movable relative to said column, and a pair of guide rails laid on a front surface of said column to extend vertically thereon and horizontally spaced apart from each other for guiding the upward and downward movement of the tool-driving unit.  The tool-driving unit includes a lift frame on the guide rails and a tilting-type turret head which is supported on a front surface of the lift frame and is rotatable about an axis inclined to the longitudinal direction of the frame on a horizon-tal plane.  One of the pair of guide rails is relatively disposed ahead of the other guide rail, so that the individual guide rails both assume positions close to the turret head thereby to minimize the amount of overhanging of the tool-driving unit.

Title: Field effect transistor
Inventor: SASAKI GORO
IPC: H01L29/812
Filed: 1987-07-21
Granted: 1992-01-07
Abstract: Abstract A field effect transistor (FET) has an In P substrate of semi-insulation material.  A non-doped Ga In As layer is epitaxially grown on the In P substrate, and an n type Ga In As P layer is epitaxially grown on the Ga In As layer. An Al In As layer is formed directly, or through another In P layer, on the Ga In As P layer by epitaxial growth.  A source electrode and a drain electrode are formed on the Al In As layer with ohmic contacts, and a gate electrode is formed on the Al In As layer with a Schottky contact.  The arrangement enables an enhancement type FET, which is superior in relation to the ease of construction of the power supply, to be of the heterojunction type using two dimensional electron gas with the advantages inherent in this type of construction.

Filed: 1987-12-11
Granted: 1993-06-29
Abstract: Abstract of the Disclosure A method for growing a Group II-VI epitaxial layer over a substrate is described.  The method includes the steps of directing a plurality of vapor flows towards the substrate, including a Group II organic vapor, a Group VI organic vapor, and a Group II elemental mercury vapor.

Abstract: ABSTRACT OF THE DISCLOSURE   Selective compliance in up to six degrees of freedom in a magnetically levitated fine motion device, or ro-bot wrist, with limited motion in X,Y,Z, ROLL, PITCH, YAW, is provided by controlled actuation cur-rents applied to six electrodynamic forcer elements. The wrist has a stator support base defining a dual periphery, carrying a number of stator magnet units. A shell flotor unit nests within the stator support base dual periphery, and carries forcer coils at locations corresponding to respective magnet units. The magnet unit and related flotor coil form a forcer element. There are a number of forcer elements. The vector sum of all the translational forces and rotational torques established at the forcer elements deter-mines the X,Y,Z, ROLL, PITCH, and YAW motion of the flotor. The flotor carries an end effector which may be a tool. Position and orientation of the flotor is monitored by light emitting diodes and lateral effect cells. Coil currents are controlled as a composite of present position, desired final position, and desired compliance. As the fine motion device approaches its final position, the control unit changes forcer coil current patterns at various sets of forcer elements, to provide selected compliance in one or more degrees of freedom while approaching and finally while maintaining the desired position. Cooling is provided as needed; docking ant locking provision is made to allow de-energizing the coils for cooling, motion of the base, or shutdown.
