Abstract: This invention is to improve procedures of maintenance of a fluid measurement system having a fluid measurement device and a control device. The fluid measurement system has a fluid measurement device and a control device to control the fluid measurement device, and the fluid measurement device comprises a fluid sensor and a related data store part configured to store fluid calculation related data for calculation of one or more fluid parameters with measurement data obtained by the fluid sensor, and the control device obtains the fluid calculation related data from the related data store part and calculates the one or more fluid parameters with the measurement data of the fluid sensor and the fluid calculation related data.

Abstract: This invention provides a diagnostic mechanism of a differential pressure type mass flow controller comprising a diagnostic parameter calculating section that obtains a mass flow rate integrated value by means of an integrating calculation from the lowering pressure value of an inlet side sensor among the inlet side sensor and an outlet side sensor arranged in communication respectively at the inlet side and the outlet side of a differential pressure generating resistive element that generates a differential pressure between the inlet and the outlet by changing a flow rate control valve arranged on the channel where a fluid flows from a flow rate control state to a closed state, and further obtains a diagnostic volume value from the obtained mass flow rate integrated value, and a comparing section that compares the diagnostic volume value obtained at the diagnostic parameter calculating section with a specified volume value.

Abstract: A glaze composition can be used to provide a glaze layer having excellent antifouling performance and visual beauty. The glaze composition contains a glaze forming material, which has a composition determined such that a baked product obtained by baking the glaze composition comprises 55.0 to 67.0 wt % of SiO2; 8.0 to 11.0 wt % of Al2O3; 2.0 to 8.0 wt % of SnO2; 15.0 to 21.0 wt % of a divalent metal oxide; and 4.0 to 6.0 wt % of a monovalent metal oxide, with respect to a total weight of the baked product. When a glaze layer is formed by use of this glaze composition, it resists contamination. Even when a dirt deposits on the glaze layer, the dirt can be easily removed from the glaze layer. In addition, the glaze composition can provide a beautiful semi-opaque glaze layer with luster and a reduction in pore generation amount.

Abstract: A deodorant composition comprises an activated carbon, a binder, an argillaceous material, and a basic zinc carbonate. A deodorant is manufactured by the following steps: (a) a mixing step of the composition materials, (b) a kneading step to knead the mixture, (c) an extrusion to shape the kneaded mixture into a honeycomb structured solid or a powder, and (d) a drying step to remove moisture from the solid. The honeycomb structured deodorant has excellent odor absorption particularly for odors, hydrocarbons, and nitrogen oxides in vehicle exhausts.
