Title: Apparatus for preventing terminal of flow passage from contamination
Inventor: SHOJI MASASHI
IPC: C02F1/32
Filed: 1988-05-23
Abstract: PURPOSE:To prevent the propagation of bacteria in a part not irradiated with ultraviolet rays by providing a back flow preventing means in a spigot so as to prevent the water discharged from the spigot from flowing backward to the flow passage at the time of the stoppage of water supply. CONSTITUTION:A bent pipe 1 composed of an ultraviolet ray permeable substance connected to a terminal straight pipe 3 in an upwardly bent state is provided in a spigot 2. When the water supply from the straight pipe 3 is stopped, the water in the spigot 2 is gradually discharged through a shower plate 2c. At this time, the water in the spigot 2 becomes violent in variation toward the lower part thereof but the water at the leading end part of the bent pipe 10 receives almost no symptons of vibration and both waters are perfectly separated and perfectly sealed by the water accumulated in the bent pipe 10 and, therefore, no air can not enter the straight pipe 3. As a result, air or water mixed with air does not reach the vicinity of the suction part of the straight pipe 3 and, even if there is a part not irradiated with ultraviolet rays, the propagation of bacteria can be prevented.

Title: Failure model for failure simulation
Inventor: MOTOMURA HIROSHI
IPC: H01L29/00
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To eliminate the defective built-in parts in an IC check mode and to produce a pattern of high reliability by keeping the output at its immediately preceding value if the output has a high impedance due to an internal failure of a block. SOLUTION: When a P type transistor TR P1 has an OFF failure, an input terminal I1 is equal to 'L'. When an input terminal I2 is equal to 'H', a P type TR P2 and an N type TR N1 are turned off with an N type TR N2 turned on respectively. At the same time, an output terminal O1 has a high impedance due to the OFF failure of the TR P1. Thereby, the terminal O1 is operated to keep its immediately preceding value. In the same way, the terminal O1 is also operated to keep its immediately preceding value in a combination of inputs of both input terminals I1 and I2 where the terminal O1 has a high impedance even against the OFF failures of the TR P2, N1 and N2 respectively.

Title: Production of single crystal
Inventor: KAWACHI AKIHIKO
IPC: C30B13/26
Filed: 1978-10-16
Abstract: PURPOSE: To easily produce a high quality single crystal of a large diameter by vertically moving a raw material rod and/or a growing crystal while turning them in production of a single crystal by a floating zone method using infrared rays.  
     CONSTITUTION: In production of a single crystal by floating zone method by which infrared rays from a halogen lamp or a xenon lamp are concentrated with a spheriocal mirror to heat melt a raw material rod followed by crystallization, the rod and a growing crystal are usually turned in opposite directions, and motions for bringing them close to each other and detaching them are repeated periodically. By this method, when they are brought close to each other, a thick melting zone is formed, resulting in a single crystal of a large diameter. As they are detached, the zone becomes thin, and infrared rays reach the central part of the rod to well heat the rod.

Abstract: PURPOSE: To surely prevent water or the like from entering the inside of a brake drum. CONSTITUTION: A base end side 19a of a tubular member 19 is fixed to a back plate 9, and a tip side 19b is inserted in an annular groove 18, a ring-shaped projecting part 20 which is radially and inwardly projected Is formed on the tip side 19b, and a ring-shaped elastic member 21 is fitted to an end part of a second flange 17 so as to be projected radially and outwardly. Because the ring-shaped part 20 which is radially and inwardly projected is formed on the tip side 19b, the clearance 22 on a second flange side becomes small and water W or the like is difficult to pass.  Because a ring-shaped elastic member 21 is fitted at the end part of the second flange 17 so as to be radially and outwardly projected, water W or the like is blocked by the elastic member 21 even when water or the like passes through the clearance 22 on the second flange side, and water or the like is prevented from entering a brake drum 7. During the assembly, the elastic member 21 is pushed by the projected part 20 and deflected, and the tubular member 19 can be easily inserted in the annular groove 18 to realize the excellent assembly.
