Title: Manufacture of compound semiconductor crystal
Inventor: MARUYAMA KENJI
IPC: H01L21/84
Filed: 1987-05-15
Abstract: PURPOSE:To form crystal in which a misfit dislocation is not created on a substrate by a method wherein, after a crystal layer of fluoride of calcium or barium and mixed crystal layers are formed so as to have thicknesses less than the critical thickness at which a misfit dislocation is not induced, a zinc telluride layer is formed and further a mercury-cadmium-tellurium compound semiconductor crystal layer is formed as an uppermost layer. CONSTITUTION:After a crystal layer 12 containing at least one of calcium fluoride, barium fluoride and strontium fluoride and mixed crystal layers 13 and 14 of the fluorides are formed so as to have thicknesses less than the critical thickness at which a misfit dislocation is not induced for the lower layer, a zinc telluride layer 15 is formed. After compound semiconductor crystal layers 16 and 17 containing at least one element among elements, i.e. zinc, mercury, cadmium and tellurium is formed on the substrate, a mercury-cadmium-tellurium compound semiconductor crystal layer 18 is formed as an uppermost layer. With this constitution, as a misfit dislocation is not created in the compound semiconductor crystal formed on the substrate, high quality compound semiconductor crystal can be obtained.

Title: Guide route controller for electromagnetic guide type travel vehicle
Inventor: KANZAKI NORIKAZU
IPC: A01M7/00
Filed: 1991-05-24
Abstract: PURPOSE:To control an electromagnetic guide type travel vehicle traveling along a guide cable so that it can easily select a guide route, such as direction change, at the branching point or the crossing of the guide cable. CONSTITUTION:A pair of right and left magnetic sensors 11a and 11b provided for the traveling travel vehicle 1 detect the strength of a magnetic field generated from the guide cable provided along the guide route. The sensors control steering to eliminate the side shift of the travel vehicle 1 as against the guide cable. When the upper part of the guide cable on a side where the travel vehicle 1 is covered by an electromagnetic shielding sheet 54, the magnetic field at a place where the guide cable branches on a plane view by one magnetic sensor cannot be detected at that place. Thus, the travel vehicle 1 can be guided so that it travels along a guide cable where the magnetic field is detected.

And when a wearing amount Ai, added in an addition means 4 in every cut completion signal 9, is fed to a comparing means 5, a device, which compares the wearring amount Ai with a saw blade cuttable limit value B set in the input means 1, outputs a saw blade exchange instruction to a cutting machine control unit 8 when the wearing amount Ai increases to the limit value B or more, exchanging the saw blade. Accordingly, the device enables the optimum exchange time of the saw blade to be instructed while the wearing amount of the saw blade to be quantitatively estimated even in a manufacture line of small quantity and multiple product kinds, and the saw blade can be used to its optimum condition.
