Title: Centrifugal turbo-machine associated with delivery regulation mechanism
Inventor: AOKI MASANORI
IPC: F04D27/00
Filed: 1984-02-06
Abstract: PURPOSE:To save energy by reducing delivery freely while reducing work (power) of impeller through simple flow regulation mechanism provided in pump casing. CONSTITUTION:Flow regulation mechanism comprising a tubular barrier board 6 is fixed at the flow-in side of guidevane 5 while at the delivery side of impeller 3 advancably/retractably in axial direction while penetrating through an intake cover 1a. When enlarging the opening of flow regulation mechanism 6 to reduce the impeller power from A to B, the head-discharge curve H (impeller power divided by delivery) will shift from (x) to (y) to operate at the cross point with the resistance curve (a) thus to reduce the delivery from Q1 to Q2. Here, the power is L'2 which is lower than the power L2 of normal centrifugal pump. Consequently, the delivery can be reduced freely while reducing the work (power) of impeller 3 through flow regulation mechanism 6 of relatively simple structure provided in the casing, resulting in saving of energy.

Title: Welding method of stainless steel
Inventor: ASAKURA JIYUUJI
IPC: B23K9/00
Filed: 1979-02-21
Abstract: PURPOSE: To obviate the deposition of chrome carbides on the front layer part of the welding heat affected zone by decarburizing stainless steel to turn the surface layer part near the weld zone to a decarburized layer then performing welding at the time of welding stainless steel to itself.  
     CONSTITUTION: C amount above the solubility limit (0.03% or more) of austenite stainless steel 1 such as SUS304 is decarburized so that at the surface layer part near the weld zone it becomes below the solubility limit. Next, the portions between the weld zones composed of the decarburized layers 5 formed are welded by using weld metal 2. According to this method, the deposition of chrome carbides on the surface layer part of the welding heat affected zone 3 forming the decarburized layer 5 does not occur even if it is heated to a carbide deposition temperature range by welding heat cycle, thus the occurrence of stress corrosion cracking may be prevented.

Abstract: PURPOSE:To enhance the stiffness of a beam and provide high precision sensibility by supporting the beam at the two ends, securing the degree of freedom in the axial direction of a probe, and preventing motions such as twisting. CONSTITUTION:The two ends of a beam 2 are supported by a supporting tool 5, and a probe 1 is installed in the middle. and through the beam 2 a contactless displacement meter 4 is installed on the side opposite to the probe 1.

A Z-axis piezo element 9 is driven by a control device 12 so that this displacement sensed is kept constant, and the gap between the probe 1 and specimen 3 is kept constant. When two-dimensional scan is made with X-axis and Y-axis piezo element 7, 8 while this condition is kept, the Z-axis piezo element changes on the basis of the surface shape of the specimen 3 so that a three-dimensional shape of the specimen surface is obtained, and it is possible to indicate the micro-structure on a display device 13.
