Filed: 1992-06-01
Abstract: PURPOSE:To prevent the mechanical interference occurring between the axes and to make the best use of the moving range of a specific axis by setting the mechanical coordinate value of the soft limit of the specific axis and the mechanical coordinate value of other axes and deciding the moving range of the specific axis corresponding to the mechanical coordinate value of the mechanical coordinate value of other axes while computing or reading the coordinate value. CONSTITUTION:The parameter input part 6 of an NC device sets the mechanical coordinate value of the soft limit of a set specific axis and the mechanical coordinate value of other axes. A comparison arithmetic part 8 calculates the mechanical coordinate value of other axes set at the part 6 and the mechanical coordinate value 7 set with the movement of other axes. In other words, the part 8 calculates the end point coordinates before the start of the movement based on the present position of a machine and the commanded movement amount. Meanwhile, the present position of the machine is read with no moving command and the soft limit of the specific axis is selected in response to the coordinate value of the machine. Then, the soft limit value 9 of the specific axis is validated. In such constitution, the mechanical interference can be prevented among the axes and the moving range of a specific axis can be used to the maximum.

Filed: 1985-06-28
Abstract: PURPOSE:To reduce the threshold current and improve the differential quantum efficiency by deciding the well width constituting a quantum well or the barrier- well energy difference so that the uppermost end of the quantum levels in the well does not match the energy level of the barrier layer. CONSTITUTION:On an N<+> GaAs substrate 1, an N<-> GaAs buffer layer 2, an N Al0.5Ga0.5As cladding layer 3, undoped multiple quantum well layers [Al0.3 Ga0.7As 4a in five layers, GaAs 4b in four layers] 4, a P<+> Al0.5Ga0.5As cladding layer 5 and a P<+> Gaas layer 6 are sequentially grown using the molecular beam epitaxy process. And a stripe electrode 7 and a back electrode 8 are formed on this wafer by vacuum deposition, and the well width is made, for instance, 74Angstrom . Since the well width is decided in such a manner that the uppermost end of the quantum levels in the well does not match the energy level of the barrier layer, the energy levels of the electrons and positive holes to be formed in the quantum well deviate from the height of the barrier layer, by which the charging into the quantum well is promoted. With this, the threshold current is reduced, and the quantum efficiency is improved.

Title: Device for blocking vapor flow from evaporating source
Inventor: KUMANO KATSUFUMI
IPC: C23C14/24
Filed: 1981-09-09
Abstract: PURPOSE:To prevent the sticking of the vapor from a evaporating source on a window for introduction of a light beam, etc. by providing a means of generating the flow of a gas between a slit provided at (near) the focus of a lens  for condensing an introducing light beam and the window for introduction. CONSTITUTION:The laser 7 emitted from a laser oscillator 5 is condensed with a lens 8, and is irradiated to the tip of a vapor depositing material 2 through a slit 10 disposed at or near the focus thereof. The tip part evaporates instantaneously but since the material 2 is let off successively from a supplying machine 3, the evaporation takes places continuously, and the evaporating material deposits on a substrate 4, thus forming a vapor deposited film. On the other hand, the evaporating material scatters toward a window 9, but the greater part thereof is shut off by the slit 10 of approximately the same diameter as the beam diameter of the laser 7. The evaporating material trying to pass through the slit is prevented from passing therethrough by the gaseous flow introduced through an inlet 11 for introduction of gas or is bent of the advancing direction, whereby the arrival at the window 9 is prevented.
