摘要： Ni-based super heat-resistant alloys have a composition in which the equilibrium precipitated amount of a gamma prime phase at 700° C. is 35 mol % or greater, and have grains having a maximum diameter of 75 nm or less in cross-sectional structure. One Ni-based super heat-resistant alloy manufacturing method includes preparing a raw material of a Ni-based super heat-resistant alloy having the aforementioned composition, and performing plastic processing of the raw material a plurality of times at a temperature of 500° C. or less so as to obtain a cumulative processing rate of 30% or greater. Another Ni-based super heat-resistant alloy manufacturing method includes preparing an alloy material having the aforementioned composition, a hardness of 500 HV or greater, and the aforementioned crystal grain maximum diameter, performing plastic processing of the alloy material at a temperature of 500° C. or less, and obtaining an alloy having a hardness of 500 HV or greater.

摘要： A mass flow controller and associated methods for providing indicated flow from the mass flow controller are disclosed. The method may include obtaining a measured flow signal indicative of a mass flow rate of a fluid that is controlled by the mass flow controller and filtering the measured flow signal to generate indicated flow that provides a representation of the actual mass flow rate of the fluid. The indicated flow is provided to an operator of the mass flow controller, and a rate of change of the mass flow rate of the fluid is determined based upon samples of the measured flow signal. A time constant used in connection with the filtering is then adjusted based upon the rate of change of the mass flow rate.

摘要： A recording means records a value of pressure of fluid on a downstream side of a differential pressure generation means during a time period after a flow control valve open and control of a flow rate is started or after the flow control valve is closed and the control of a flow rate is stopped until a measured flow rate becomes stable, and a diagnostic means contrasts a controlled value acquired based in a value of the pressure of the fluid on the downstream side recorded by the recording means, with a controlled value when abnormality has not occurred, and diagnoses that abnormality has occurred in the flow meter when a difference between the both controlled values exceeds a threshold. Thereby, a mass flow controller and a diagnostic method which can simply diagnose generation of abnormality in a differential pressure type flow meter without requiring time only for performing the diagnosis.

摘要： A method for testing a multicore cable that includes a single common shield covering plural insulated wires. The testing method includes inputting a test signal, by capacitive coupling, to an end portion of the insulated wire under test among end portions of the insulated wires exposed at one end of the multicore cable, and measuring voltages of output signals output by capacitive coupling respectively from end portions of the insulated wires exposed at the other end of the multicore cable, and identifying the other end portion of the insulated wire under test based on the measured voltages. The voltages of output signals are measured in a state that an output variation reduction capacitive element is connected in series with a coupling capacitance generated by the capacitive coupling.
