Title: Butterfly valve with steam trap
Inventor: FUJITA SATOYUKI
IPC: F16T1/02
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To enable not only a function of steam trap but also a function of a temperature adjusting valve to be carried out by a method wherein a temperature responding element displaced in response to a temperature of fluid is oppositely arranged in a through-pass hole passing through an inlet and an outlet formed in a disk-like valve element. SOLUTION: The central part of a valve element 4 is provided with a detent part 11, a disk-like screen 12 for filtering some foreign material contained in fluid is fixed to the inlet port 2 and at the same time a temperature responding element 5 is arranged in the screen. The temperature responding element 5 is a closed body capsule of substantial disk-like member which is formed by a thin film diaphragm and with thermal expanding or shrunk liquid filled in it. A plurality of locations at an entire circumference of the temperature responding element 5 are held by a holding guide 13 and the bottom surface of the holding guide 13 is fixed to a valve element 4 by a trap valve seat 15. A through-pass hole 6 is formed at the central part of the trap valve seat 15.  The thermal expansion or shrinking capsule 5 acting as the temperature responding element is expanded to close the through-pass hole 6 and shrunk to open the through-pass hole 6 as shown in the drawing, and so this valve may act as a so-called temperature adjusting valve.

Title: Manufacture of semiconductor substrate
Inventor: YOSHIHARA SHINJI
IPC: H01L27/12
Filed: 1993-02-19
Abstract: PURPOSE:To provide a method of manufacturing an SOI substrate of low cost wherein an SOI having a desired thickness and area can be formed. CONSTITUTION:A seed part is formed in an insulating film on an Si substrate, and an Si layer is grown so as to have a thickness larger than that of the insulating film, in a chamber wherein Si epitaxial growth gas is applied to the seed part (step 1-3). Next the epitaxial growth gas is discharged (step 1-4). While ultraviolet rays are applied, etching gas is introduced (step 1-5). Since the upper surface of an epitaxial Si layer is directly irradiated with the ultraviolet rays, etching of the upper surface is more progressed than that of the side wall part. Thus the etching becomes anisotropic, so that the area of the epitaxially grown Si layer is scarcely decreased, and only the thickness of the layer is decreased. Next, the etching gas is discharged (step 1-6). If necessary, the epitaxial growth gas is again introduced, and the Si layer is further grown. Epitaxial growth progresses isotropically, so that the lateral direction, i.e., the area also is increased.

Abstract: PURPOSE:To perform a speed control system which has a rapid responsiveness and excellent stability by presuming the speed of the end of a machine load and the torque stress or an elastic displacement of a load feeding system from a speed signal and a torque command signal by a presuming unit. CONSTITUTION:A torque command signal (u) is output in response to a deviation between a torque command (r) and a speed signal (v). A presuming unit 1 presumes a torque stress or an elastic displacement (d) of a machine load feeding system and an end speed vl of the machine load from the signals (v) and (u) to obtain presumed values -d and -vl. The obtained values -d and -vl are added to the command (u). Thus, a speed control system which has a high speed responsiveness and excellent stability can be provided without using a sensor.

Abstract: PURPOSE:To dispense with the need to absorb changes in position by means of connected piping by connecting drain tanks for collecting drainage produced in heat-transfer tubes to the cylindrical main body of a moisture-separating heating device in such a manner as to have the drain tanks supported by the cylindrical main body of the moisture-separating heating device. CONSTITUTION:To the lower part of a cylindrical main body 22 is connected a cloth-around pipe 4 by which cycling steam flows in and to the upper part is connected a cloth-around pipe 6 by which the cycling steam flows out; heated- steam drain tanks 20, 21 are supported respectively by supporting plates 32a, 32b with the intermediary of hangers 33a, 33b. Even when the cloth-around tubes, and the like change their positions through expansion with start-up of th plant, the heated-steam drain tanks 20, 21 change their positions together with the main body 22. This constitution thus dispenses with bent piping or use of long heated-steam drain pipes for the connection of the heated-steam drain tanks 20, 21 to the cylindrical main body 22 of the moisture-separating heating device.
