Title: Aligner
Inventor: YAMAMOTO YUKIHIRO
IPC: G01B11/02
Filed: 1988-06-13
Abstract: PURPOSE:To make it possible to make the dimension of patterns on semiconductor wafers constant regardless of error in the manufacture of photomasks by a method wherein photomask dimension measurement function is added to an aligner and exposure dose amount is varied according to the results of the measurement. CONSTITUTION:A photomask 3 having a pattern to be transferred is firstly fixed on an aligner. A measurement light flux 10 is radiated from a measurement light source 9 and it reaches a light receiving section 13 via the photomask 3 and a lens 12. Four patterns 11 for dimension measurement is positioned on the photomask 3, and its average value is determined. Next, this dimension measurement data is sent to a control system 8. In the case of the photomask 3 measured this time, it is calculated that how much of the exposure dose amount it to be adjusted to make the dimensions of a photoresist pattern on the semiconductor wafer 6 agree with a reference value, and an instruction is issued to a lighting optical system 1. Therefore, even when error in manufacture of two photomasks exists, the dimensions of the pattern on the semiconductor wafer 6 manufactured by using the two photomasks become the same.

Abstract: PURPOSE:To improve the heat transfer performance of the finned heat exchanger by setting the tube pitch of a flat heat transfer tube in a direction rectangular to an airstream direction larger than that in the airstream direction and allowing the long axis of the flat heat transfer tube to have a certain angle with respect to the airstream direction, and providing a plurality of slits opened in the airstream direction on flat fins disposed between the flat heat transfer tube. CONSTITUTION:The tube pitch in a direction rectangular to an airstream direction of a flat heat transfer tube is made larger than that in an airstream direction of a flat heat transfer tube 8, and the long axis of the heat transfer tube is allowed to have a certain angle with respect to an airstream direction 9. Slits 10 opening at two sides opposite to the airstream direction 9 on flat fins 6 between flat heat transfer tubes 8, are provided at the upper and lower parts using flat fins 6 as base plates. By this construction, flow-in is generated in the rear stream of the flat heat transfer tube 8 and the size of a dead water zone 12 is largely reduced. Further, since it becomes possible to suppress the development of a temperature interfacial layer, the front edge effect of the interfacial layer due to the slits 10 is amply displayed on the downstream side of the flat fines 6.

Abstract: PURPOSE:To simply and inexpensively form the whole production line, and also, to quicken a flow of the whole line by generating new recognition information corresponding to image data, based on the image data which has been stored in advance at the time of a teaching mode, when an image processor receives stage variation information of a pallet. CONSTITUTION:In case of a pallet 8 of the second stage, a distance between a camera 1 and a work plane of a robot 6 becomes longer than that of the first stage, therefore, an image becomes small. Therefore, by taking notice of an area in recognition data which has been registered in advance at the time of teaching, a ratio of this area and an area of a recognition object work which has been obtained by reading an image of the second stage is derived, and by multiplying this ratio by an area of an image obtained by the second stage, new recognition data is generated. Also, by registering this ratio in a storage circuit 12 and multiplying this ratio by the recognition data whenever the stage of the pallet changes, new recognition data is generated. This processing is executed by a stage number portion of the pallet. In such a way, even if a position in which a recognition object work has been placed, that is, a work plane changes, the recognition object work can be recognized, and also, teaching of once will suffice as usual.

Title: Separate tapping method for molten steel and slag, and its apparatus
Inventor: NAKANISHI KIYOUJI
IPC: C21C5/46
Filed: 1979-11-14
Abstract: PURPOSE:To prevent flowing out of slag and to improve available percentage of molten steel, by detecting arriving of slag in the tapping passage from the reduced speed of molten steel flow at the last period of molten steel taking out work and by adjusting tilting angle of the furnace body in accordance with the detected signal. CONSTITUTION:When slag 7 comes out into descending passage 8 of tapping passage 5 at the last period of molten steel taking out work, a sudden reduction in the flowing speed of molten steel occurs due to a density variation at the curved section of tapping passage, because of the molten steel remained in the ascending passage 12 of curved section. Measuring terminals 9 and 9' detect arriving of slag 7 through variation in electric resistance generated by penetration of slag 7 into descending passage 8. When this detecting signal is received tilting of furnace body 1 is restored toward the original state by driving the converter driving motor through a prescribed electric circuit. As a result, disadvantages, such as rephosphorization caused by admixture of slag which could not be avoided before, lowering of available percentage of adding alloy, wear of ladle refractories, etc., can be solved.
