Title: Light source unit for multibeam plotting recorder and method for adjusting light beam emitting direction of led in light source unit
Inventor: WASHIYAMA HIROYUKI
IPC: H04N1/036
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To arrange a plurality of light emitting diodes two-dimensionally easily and accurately by arranging a plurality of hollow members of specified shape inserted with a plurality of light emitting diodes, a planar member having a plurality of openings to be fitted with the hollow members arranged specifically, and the like. SOLUTION: A light emitting diode LED 42 is selected after a tubular member 50 is bonded thereto and under a state where the positional relationship is determined between the LED 42 and the tubular member 50, the LED 42 is set in a specified jig and irradiated with light. The LED 42 is selected depending on the fact that the irradiating direction of a light peak part comes within a specified range. Since the tubular member 50 is bonded to the LED 42, the irradiating direction of a light peak part when the LED 42 is set in a jig through the tubular member 50 is identical to that when the LED 42 is fixed to an LED holder. More specifically, the irradiating direction of a light peak part has reproducibility because the tubular member 50 is bonded to the LED 42.

Abstract: PURPOSE:To stably produce a thin slab having good surface characteristic by setting scum weirs under regulating dipping depth into molten metal and distance between a cooling drum and meniscus to the scum weir to the specific ranges over the width direction of cooling drums. CONSTITUTION:Main stream of molten steel 5 flows as showing as the solid lines in the upper figure and is interrupted with the scum weir 6, but in the case the dipping depth of scum weir 6 exceeds 15mm the stream is developed as showing as the dotted line, and eddy or waving in between the scum weir 6 and the cooling drum 1 or strong stream to drum axial direction is developed. From the above result, by dipping the scum weir into the molten steel 5 under regulating in the range of a-b-c-d in the lower figure, the stream at the meniscus R becomes <=3m/min at the max. velocity and further, the eddy is not developed and the waving is made to form the molten metal surface having <=5mm amplitude without any disturbance. Therefore, the thin slab having excellent surface characteristic without involuving any scum and developing any surface crack on the cast slab S can be produced.

Title: Method of estimating epitaxial wafer for light emitting diode
Inventor: KURIHARA TORU
IPC: H01L21/66
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To judge quality of crystallinity of a P-N junction part, by grasping the degree of supersaturation at the time of epitaxial growth by using depth direction distribution of carrier concentration in the vicinity of the P-N junction part, from the surface side of an epitaxial wafer to the board side. SOLUTION: Carrier concentration of an epitaxial layer is changed by the amount of dopant captured in crystal at the time of growth. Under a stable growth condition, distribution of the carrier concentration in the depth direction of the epitaxial layer follows the intrinsic physical properties which elements constituting a crystal and elements turning to dopant have to the temperature at the time of growth. In the case of the growth condition wherein the degree of supersaturation is increased more than the necessary level, change is generated in the distribution of concentration. Quality of light emitting characteristics can be judged by measuring the distribution of carrier concentration in the vicinity of a P-N junction, in the state of an epitaxial wafer.
