Title: Measurement of approximate yield strength mainly for metal material
Inventor: MAEKAWA AKIRA
IPC: G01N3/08
Filed: 1988-12-09
Abstract: PURPOSE:To enable simple and quick measurement of approximate yield strength by setting a ratio of a value of a tensile load rising rate at a yield strength point obtained empirically for individual material of a test piece for a value of a tensile load rising rate of the test piece stored and fixed by a memory/fixing means for the tensile load means rising rate. CONSTITUTION:When a load rate constant device 2 is used, a load rate dp/dt =ten theta1 is fixed before a yielding, showing a proportional range. In the second half of the proportional range, a value (voltage) of a tensile load rising rate is stored by a memory/fixing means 3 for a tensile load rising rate to fix a mechanical tensile rate at the moment. A value (electric energy) of tantheta2, for example, tantheta2/tantheta1 = k (k is 0-100%) is set and stored on a comparison detec tion means 4 for a load rate with a setting device 4. A value of tantheta2 is obtained empirically in terms of the type of a test piece. A changing load rate tantheta is compared with the load rate tantheta2 set to detect a point of tantheta=tantheta2. Thus, an approximate yield strength of material is given by a load at this point.

Title: Steam turbine
Inventor: NIKORAI NIKORAEUITSUCHI GUDOKO
IPC: F01D9/06
Filed: 1987-12-10
Abstract: PURPOSE: To improve the reliability and durability of a valve chamber and to shorten the start time of a turbine by arranging a valve chamber between an inner and an outer casing, and firmly fixing it on the outer casing. CONSTITUTION: While a turbine is working, the temperature difference and the pressure difference acting on the wall of the valve 16 equals to the temperature difference and the pressure difference of the steam delivered to a nozzle chamber 7 and the steam between the inner and the outer casing 4, 9. Therefore, as the temperature difference and the pressure difference acting on the wall of the valve chamber 16 is smaller than the traditional one, the mechanical stress and the thermal stress acting on the wall is therewith smaller, its reliability and durability are therefore improved. And, while starting the turbine, the valve chamber 16 and its interior are meanwhile heated from outside, the heating from outside is realized by a steam flowing through the space between the inner and the outer casing 4, 9.  By this constitution, as the valve chamber 16 is heated from both inside and outside, the necessary start time for starting the turbine is shortened.
