Title: Steam generator
Inventor: KAMIMURA YUTAKA
IPC: F22B37/26
Filed: 1987-12-21
Abstract: PURPOSE: To provide a steam generator from which high-quality steam can be obtained, by constituting a can body in such a way that the water drops adhering to the internal upper and side faces of the can body do not come out together with the steam by protruding the steam outlet of the can body into the upper space in the can body. CONSTITUTION: In a can body 2, the steam outlet 5 of the body 2 is protruded one dimension into the upper space and a water inlet 4, and upper and lower sensors 9 and 10 which maintain the water level in the can body 2 are provided in the water 6 contained in the can body 2. When a burner 1 is ignited, fins 3 absorb heat and generate steam 7 by boiling the water 6 in the can body 2. When the water 6 is boiled, the water surface in the can body 2 runs in waves, and water drops 8 are scattered and adhere to the internal upper and side faces of the can body 2. The generated steam 7 is moved to the steam outlet 5 (as shown by the arrow C) and discharged from the outlet 5 by the steam pressure.  When the steam 7 is discharged from the outlet 5, the water drops 8 adhering to the internal upper and side faces of the can body 2 also moves in the direction shown by the arrow C, but, the outlet 5 is protruded in the opposite direction, the water drops 8 are not sucked into the outlet 5, but drop onto the surface of the water 6 and are again evaporated. This cycle is repeated. The steam 7, on the other hand, is efficiently separated from the water drops 8 and high-quality steam is obtained from the can body 2.

Title: Apparatus for lifting out of pure water and drying
Inventor: SAEGUSA HARUO
IPC: H01L21/304
Filed: 1989-12-13
Abstract: PURPOSE:To improve drying quality by providing a function of removing bubbles in pure water to be supplied to a pure water tank, and lifting a substrate while always allowing the water of the tank to overflow. CONSTITUTION:A lifting out of pure water and drying apparatus for lifting a substrate at an extremely low speed from a pure water tank 1 and drying it has a function of removing bubbles in the pure water to be supplied to the tank 1. For example, before the water heated by a pure water heating unit 15 and mixed with bubbles of steam is introduced to the tank 1, the bubbles in the hot water is separated by a bubble removing tank 12. The bubbles are moved to the top of the tank 12, drained from a bubble drain pipe 13, and the hot pure water is supplied to the tank 1 in a state having no bubble in the water. Thus, since the waving of the surface of the water of the tank 1 due to the bubbles in the wafer is eliminated, the substrate can be lifted while always allowing the water of the tank 1 to overflow. Accordingly, particles of the surface layer of the tank 1 can be reduced, and drying quality of the substrate can be improved.

Abstract: PROBLEM TO BE SOLVED: To reduce test pattern generation time and the number of test patterns when generating the failure detection test pattern of a logic circuit. SOLUTION: A target failure is selected from a created failure table (S103), a test pattern for detecting the target failure is generated (S104), a failure definition is made to all failures (S105), a failure simulation is performed (S106), a failure table is updated (S107), processing's S103-S107 are repeated until all failures are detected, and a redundant part is deleted from the test pattern (S108). In this case, the test pattern is successively selected from the test patterns with less number of failure detection, it is judged whether all failures detected by the test pattern can also be detected by another test pattern or not, and the test pattern is deleted as a redundant pattern when the failures can also be detected by other test patterns.
