Abstract: Provided is at least one of an improvement in the thermal stability of a CHA-type zeolite, which is achieved by a method different from that of the related art for improving thermal stability; a method for producing a CHA-type zeolite that improves thermal stability; and such a CHA-type zeolite. Provided is a CHA-type zeolite having a 1H-MAS-NMR spectrum and an IR spectrum in which, preferably, in the 1H-MAS-NMR spectrum, a ratio of an integrated intensity of a maximum peak having a peak top at a chemical shift of 3.0 to 3.5 ppm to an integrated intensity of a maximum peak having a peak top at a chemical shift of 4.0 to 4.5 ppm is greater than 0.12 and 0.5 or less, and, in the IR spectrum, a ratio of a maximum peak height of an absorption peak having a peak top at a wavenumber of 3630 cm?1 or greater and 3650 cm?1 or less to a maximum peak height of an absorption peak having a peak top at a wavenumber of 3590 cm?1 or greater and 3610 cm?1 or less is 0.40 or greater and 1.0 or less.

Abstract: A diagnostic device includes: a generation circuit that generates an inspection signal that is an alternating current signal of a single frequency, a conversion circuit that converts, into a direct current signal, a response signal of a piezoelectric element in response to the inspection signal, and a controller that analyzes the direct current signal and determines whether the piezoelectric element operates normally based on the analysis of the direct current signal.

Abstract: A cutting liquid supply device in a machine tool is configured to remove gas mixed in a cutting liquid supply line to improve the response of discharging a mist of cutting liquid. Cutting liquid is supplied from a pump (42) through a rotary joint (28) to a mist generation device (24) within a rotating spindle (29). The pressure of the cutting liquid is measured by a pressure sensor (47). An air vent device (30) for opening and closing, with respect to atmospheric pressure, piping (3) that supplies the cutting liquid is provided above the rotary joint (28). A detection signal is inputted in the control board (70) from the pressure sensor (47), and when the control board (70) detects, after the pump (42) stops the supply of the cutting liquid to the piping (3), that the pressure of the cutting liquid does not decrease to a level lower than a predetermined threshold value, the control board (70) instructs the air vent device (30) to open the piping (4) to the atmosphere.
