Title: Condensation vaporizer
Inventor: FUJITA IKUO
IPC: B01D5/00
Filed: 1988-08-31
Abstract: PURPOSE:To make it possible to heat liquefied oxygen more effectively by forming a condensation passage which has a downward inclination in terms of a horizontal direction from an introduction inlet of gas to a discharge outlet of condensed liquid, and reducing a drop in a heat transfer capacity due to a condensed liquid of nitrogen gas. CONSTITUTION:Nitrogen NG introduced into a condensation vaporizer 20 is introduced into each condensation n flow passage 25 on an equal basis by way of an inlet header 27 from the upper part of a lower part tower 13. The nitrogen gas GN present in the flow passage 25 exchanges heat with liquefied oxygen LO in an adjoining oxygen chamber 2. While it is being condensed, the liquefied nitrogen gas flows toward the outlet of the condensed liquid 24 through a downward inclination of each condensation passage 25 and flows down from the outlet 24 and is discharged from an outlet header 28. At that time, non-condensation gas GX contained in the nitrogen gas GN is discharged from a purge nozzle 27a installed at the upper part of the inlet header 27. In this manner, film heat transfer coefficients in the vertical direction in a nitrogen chamber can be almost identical to each other. Therefore, this construction makes it possible to exchange heat with the liquefied oxygen OL in the lower part of the oxygen chamber 2 to a satisfactory extent, thereby exerting the maximum heat transfer performance due to condensation vaporization.

The formation of the wells of the potential for the electrons in the transmission band and the formation of the wells for the holes in the valency bands are made possible by combining the layers of these three semiconductor materials having the widths of the different forbidden bands.  As a result, the application to an optical device to be actively led in the range of the medium IR rays or far IR rays is made possible.

Filed: 1990-08-20
Abstract: PURPOSE:To make the accuracy of vehicle kind decision making high and to make the kinds of classifications more by comparing time-series features of electric outputs corresponding to a series of inductance variation generated every time a traveling vehicle passes a loop coil with plural time-series features corresponding to the kinds of traveling vehicles, and determining the most similar feature.

The features are compared by a vehicle kind decision means 5 with features of sampled data by the kinds of vehicles stored in a sample means 4 and an additional sample storage means 6 to determine the most similar sample data. The vehicle kind decision means 5 sends out a vehicle kind decision signal indicating clearly the kind of the vehicle corresponding to the determined sample data to a following device or transmission line. Consequently, the number of the kinds of classifications can be increased and the kind of the traveling vehicle can be decided with high vehicle kind decision accuracy.
