Patent JP-H03236218-A (JP)
Title: Compound semiconductor substrate and manufacture thereof
Inventor: IWASAKI HIROSHI
IPC: H01L21/20
Filed: 1990-02-14
Abstract: PURPOSE:To obtain a compound semiconductor substrate whose dislocation density is less by providing undoped semi-insulating epitaxial compound semiconductor substrate on a compound semiconductor substrate having the specified conductivity type and the specified impurity concentration or higher. CONSTITUTION:As the impurity concentration of a compound semiconductor substrate, 5X10<17>cm<-3> or higher is required. For example, the substrate is cut out of an N-type GaAs single crystal having low dislocation density obtained by lifting N-type GaAs wherein a silicon element is added as impurities by 5X10<17>cm<-3> or higher by an LEC method. Thus a substrate 1 for epitaxial growth is obtained. Mirror surface treatment, chemical treatment and the like are performed on the surface of the substrate 1. An undoped semi-insulating GaAs crystal layer 2 is epitaxially grown on the surface. Then, the high-quality compound semiconductor substrate having the low dislocation density with the semi-insulating property being maintained is obtained. As the film thickness (t) of the crystal 2, the minimum thickness required for the active region of an element formed in the crystal layer is necessary. When any of MBE, MOCVD or MOMBE is used for the epitaxial growth of the crystal layer 2, the controllability of the film thickness (t) and the film quality can be improved.

Abstract: PURPOSE:To make it possible to apply a positioning operation with desired accuracy to a multi-joint robot without directly influencing the resolution performance of a detecting means installed on a multi-joint arm by providing a means for instructing the displacement given to an instruction arm after enlarging or contracting it by a desired magnification. CONSTITUTION:When an operator gives a motion to an instructing multi-joint robot 1, the given displacement is fed in a control means 3 on the basis of the operation of a switch means 15. Then, this control means 3 finds out the coordinates, in a space coordinates system, corresponding to the displacement of an instructing multi-joint arm 2 through a prescribed way of calculation on the basis of detected signals from respective detecting means 7, 9, 11 and 13, while on the other hand, reads a desired magnification setting signal from a magnification setting means 14 so as to find out the enlarged or contracted amount of relative displacement to be given to this robot 1 so that a movement instruction may be given to the multi-joint robot 1. As the result, it is possible to have the multi-joint robot 1 subjected to a positioning operation with desired accuracy regardless of the resolution performance of the detecting means 7, 9, 11 and 13.

Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To control the humidity increase in purified air discharged from an air outlet by mixing ethylene glycol into water to be mixed and brought into contact with dust. SOLUTION: Air containing dust is supplied to a dust removing channel 11 and mixed and brought into contact with the mixed solution of fog-shaped water and ethylene glycol while ascending in the channel 11.

When the dust and the mixed solution pass through a dust removing filter 21 between partition plates 9, 10, most of the dust is removed and most of the mixed solution is adsorbed by the filter 21. By passing through the filter 21 of fine meshes between the partition plate 10 and a side plate 4b, air which passed through the filter 21 and was nearly purified is discharged outside an apparatus as purified air. The dust which dropped into the tank 2 precipitates by its own weight, is transferred by a discharge conveyer 16, and is received by a dust collecting box 18.

Abstract: PURPOSE:To enhance the focus uniformity in the center and the circumference of the picture screen of a picture tube, by rendering the electron beam-passing hole of the fourth lattice to be rotation-asymmetric, and said holes of the other lattices to be rotation-asymmetric. CONSTITUTION:The shape of the electron beam-passing hole of the fourth lattice is not round. The plate thickness of the fourth lattice is forced to be thin towards the horizontal axis direction and thick towards the perpendicular axis direction. The electron beam-passing hole is composed of two rectangules where the two long axes intercept each other at a right angle. Also, the tube-axis-direction-depth 63 of a rectangular hole 62 whose long axis is parallel with the horizontal axis is larger than other depth 601, and further, the shape of the common hole 64 of the two rectangular holes is preferable to be a regular square, so that the shape of the electron beam does not become an oblong in the central area. Consequently, the image-resolution on the circumference of the picture screen can be greatly enhanced without lowering the image-resolution in the center of the picture screen of the picture tube.
