Title: Wire drawing device having surface flaw detector
Inventor: OKANO KIMITAKA
IPC: G01N27/82
Filed: 1979-07-12
Abstract: PURPOSE: To effectively suppress the oscillation of wire by arranging three wire drawing dies in a specific manner on a surface flaw detector.  
     CONSTITUTION: A group of wire drawing dies 6 and 7, each containing three or more dies of the reduction difference less than 30% and arrayed substantially in a row, is disposed at each of the upstream and downstream sides of a surface flaw detector 3. The distance between two groups 6, 7 is selected to fall between 100 and 1,500mm. In operation, the wire 1 supplied from a wire swift 2 is made to run through the dies of the group 6, measuring section 4 of the surface flaw detector 3 for detection of any surface flaw and then through the dies of the group 7. The wire is then wound round a take-up drum 5. According to this arrangement, the oscillation of the wire 1 is greatly suppressed to permit an accurate and smooth operation of the surface flaw detector 3.

Abstract: PROBLEM TO BE SOLVED: To position the ends of all elastic bodies on one and the same plane, and thus prevent a large step to be formed on the driving face of a stator, by bringing the end of the elastic bodies into contact with the reference plane contained in a positioning member. SOLUTION: One of two semicolumnar elastic bodies is placed on the base plate 62 of an assembling jig. Then, a first piezoelectric body layer, an electrode plate, a second piezoelectric body layer and the other piezoelectric body are placed on the one of the elastic bodies in this order. A pressure receiving member 70 is pressed against the driving faces of the elastic bodies, and two flank pressing members 66 are pressed against the elastic bodies from the circumference side. Thereby, the piezoelectric bodies and so on are positioned in the direction of the radius. A pressing member 72 is pressed from the opposite side to the pressure receiving member 70, thereby positioning the driving faces of the elastic bodies on one and the same plane.  The driving face of a stator 30 is ground and flattened to the extent that the driving face can favorably slide on the sliding material of a mover, thereby enhancing the efficiency of the production of the vibration actuator.

Title: Ceramic gas turbine
Inventor: WADA KATSUO
IPC: F02C9/18
Filed: 1988-04-13
Abstract: PURPOSE:To reduce flow rate of working fluid appropriately and reduce thermal stress of a ceramic member by a method wherein when a gas turbine suddenly stops, a passage area of an air flow path from a compressor to a combustor is reduced and at the same time an opening communicating with outside an instrument is opened. CONSTITUTION:Air compressed by a compressor 1 is supplied to a combustor 2. Fuel is injected from a fuel nozzle 3 and burned in the combustor 2. Burned gas is further supplied via a stationary blade 4 to a moving blade 5 to generate power. At least one of the combustor 2, the stationary blade 4 and the moving blade 5 is made of ceramic. In this constitution, fuel is cut when a gas turbine suddenly stops. At the same time, a combustor flow rate adjusting valve 6 is closed and an adjusting valve 9 which communicates with an exhaust hole 8 outside an instrument is opened. This decreases an amount of working fluid flowing in the turbine and lowers thermal stress of the ceramic member, preventing damage.
