摘要:
A body section having a main channel through which a fluid to be measured flows and sections for shunting the fluid to be measured from the main channel, and a fluid measuring section provided removably from the body section and measuring the flow rate of the fluid to be measured flowing through the main channel based on the detection results of the fluid to be measured introduced from the shunting section. The fluid measuring section is fixed to the body section and shunt ratio data, i.e. the adjustment data about measurement processing inherent to the constitution of the body section, is registered in the fluid measuring section before adjusting measurement processing.

A battery includes: a battery element having a cathode and an anode; a package can containing the battery element and being electrically connected to one of the cathode and the anode; and external connection terminal being connected to the other one of the cathode and the anode; and having a plate-like base contained in the package can and a leading portion extending to outside of the package can; and an insulating member separating the external connection terminal from the battery element. The base of the external connection terminal is spaced from an internal wall face of the package can, and the insulating member has notches at a position where the base of the external connection terminal is layered on the insulating member in the thickness direction of the package can.

A simply structured flowmeter in which an influence of a dilatational wave on a thermal flow rate sensor is suppressed, and measurement accuracy is enhanced.The flowmeter has not only the thermal flow rate sensor that is placed to face a flow channel and detects a flow rate of fluid flowing through the flow channel but also a micro path (for example, narrow pipe) that is provided to the flow channel and blocks a dilatational wave created in the flow channel from being transmitted to the thermal flow rate sensor.
摘要:
A thermal flow meter has a sensor chip, a heater, first and second flow rate calculators, and an output controller. The heater increases the ambient temperature in the vicinity of a pair of temperature-sensing elements on the sensor chip by a particular temperature above a temperature of a fluid flowing along the sensor chip. The first flow rate calculator calculates a flow rate of the fluid from a temperature difference detected by the pair of temperature-sensing elements. The second flow rate calculator calculates a flow rate of the fluid from a driving energy of the heater. The output controller outputs the flow rate calculated by the second flow rate calculator, instead of the flow rate calculated by the first flow rate calculator, when the flow rate calculated by the first flow rate calculator exceeds a flow rate threshold value that is set in advance.

A non-aqueous electrolyte secondary cell in which inner shorting may be prevented from occurring and which is improved in operational reliability and safety. The non-aqueous electrolyte secondary cell is comprised of an electrode unit loaded in a cell casing. The electrode unit is comprised at least of a strip-shaped cathode and a strip-shaped anode layered together and coiled longitudinally around a center pin.
