Provided is a novel crystalline solid electrolyte which can be used as a dispersion medium when slurrying polar solvents such as NMP, acetone, and DMF, and for which a decrease in conductivity when the crystalline solid electrolyte is immersed in said solvents can be suppressed. Proposed is a crystalline solid electrolyte represented by Compositional Formula: LiSiPSHa(here, Ha includes one or two or more of Br, Cl, I, and F, and 2.4&#x3c;(x&#x2212;y)/(y+z)&#x3c;3.3), in which the content of S is 55 to 73% by mass, the content of Si is 2 to 11% by mass, and the content of a Ha element is 0.02% by mass or more.

Crystalline solid electrolyte and production method therefor

A thermal sensor in which, when an object to be measured is a water-based liquid, attachment of air bubbles to the external surface of the sensor is reduced to improve measurement accuracy. The thermal sensor has a sensing element () including a heat producing body and a temperature sensing body, a resin mold () for sealing the sensing element (), and a heat transmission member () for transmitting heat between the sensing element () and a water-based object to be measured. A part of the heat transmission member () is exposed from the resin mold () to form an exposed surface section. A hydrophilic film () formed of a silicon oxide film is applied to the exposed surface section and to that part of the surface of the resin mold which is positioned around the exposed surface section.

A flow rate/liquid type detecting method for detecting the flow rate of a fluid and, at the same time, detecting any one of or both the type of the fluid and the concentration of the fluid, characterized in that, by using a flow rate/liquid type detecting apparatus comprising: a main passage through which a fluid to be detected flows, an auxiliary passage branched from the main passage, and a flow rate/liquid type detecting sensor device provided in the auxiliary passage, is provided, and in conducting any one of or both the detection of the type of the fluid and the detection of the concentration of the fluid, the auxiliary passage opening/closing valve is closed, and the fluid is allowed to temporarily stay within the flow rate/liquid type detecting sensor device to conduct any one of or both the detection of the liquid type and the detection of the concentration, and in detecting the flow rate of the fluid detected, the auxiliary passage opening/closing valve is opened to allow the fluid to flow into the flow rate/liquid type detecting sensor device to detect the flow rate.

A flow rate/liquid type detecting method for detecting the flow rate of a fluid and, at the same time, detecting any one of or both the type of the fluid and the concentration of the fluid, characterized in that: by using a flow rate/liquid type detecting apparatus comprising a main passage through which a fluid to be detected flows, an auxiliary passage branched from the main passage, and a flow rate/liquid type detecting sensor device provided in the auxiliary passage, is provided, and in conducting any one of or both the detection of the type of the fluid to be detected and the detection of the concentration of the fluid to be detected, an auxiliary passage opening/closing valve is closed, and the fluid to be detected is allowed to temporarily stay within the flow rate/liquid type detecting sensor device to conduct any one of or both the detection of the liquid type and the detection of the concentration, and in detecting the flow rate of the fluid to be detected, the auxiliary passage opening/closing valve is opened to allow the fluid to be detected to flow into the flow rate/liquid type detecting sensor device to detect the flow rate.

A pipe line for fluid to be detected is formed so that heat from a flow rate detector in which a thin-film heating element and a thin-film temperature sensing element are laminated on a first surface of a substrate through an insulating layer is transferred to and absorbed by the fluid. In the flow rate detector, the temperature sensing which is affected by the heat absorption of the fluid due to the heating of the thin-film heating element is executed by the thin-film temperature sensing element, and the flow rate of the fluid in the pipe line is detected on the basis of the temperature sensing result. A fin plate extending into the pipe line is joined to a second surface of the substrate of the flow rate detector by a joint member, and the fin plate extends so as to pass through the central portion on the circular section of the pipe line. The dimension of the fin plate in the direction of the pipe line is larger than the dimension L of the thickness. Accordingly, even when the fluid is viscous fluid having relatively high viscosity, and further even when the flow rate is relatively small or under a broad environmental temperature condition, the flow rate of the fluid-flowing in the pipe line can be accurately measured.

Flow rate sensor, flow meter, and discharge rate control apparatus for liquid discharge machines

A flow rate sensor for performing a flow rate detection of fluid with high accuracy without suffering adverse effect of the environmental temperature condition even when the fluid is viscous fluid having relatively high viscosity or the flow rate is relatively small is provided. The flow rate sensor includes a flow rate detector having a heating function and a temperature sensing function, and a pipe line for fluid to be detected which is formed so that heat from the flow rate detector is transferred to and absorbed by the fluid. The temperature sensing which is affected by a heat absorption effect of the fluid due to the heat is executed in the flow rate detector, and the flow rate of the fluid in the pipe line is detected on the basis of the temperature sensing result. Unit retaining portions formed on a casing in which the pipe line is formed, the unit retaining portions being disposed adjacent to the pipe line. A flow rate detecting unit comprising the flow rate detector is retained by the unit retaining portion, and a temperature detecting unit comprising a fluid temperature detector is retained by the unit retaining portion.
