Abstract: A temperature sensor having a structure in which electrode wires are butted against signal wires with their weld portions and a method for manufacturing the temperature sensor. In a temperature sensor (1), outer circumferential portions (57a) and (57b) of each of weld portions (55) between electrode wires (25) and sheath core wires (3) are located outward of a first straight line D1 and a second straight line D2, respectively. A forward end-side length L1 is set to be longer than a rear end-side length L2. In addition, the sheath core wires (3) are larger in diameter than the electrode wires (25).

Abstract: Objects of the present invention are to provide a mayenite compound which can induce electron donation reaction, H? donation reaction, deoxygenation reaction, and dehydration reaction; a multifunctional agent which contains the mayenite compound which is not dissolved in a solvent, and which can induce electron donation reaction, H? donation reaction, deoxygenation reaction, and dehydration reaction; and a method for producing a mayenite-compound-containing product. The invention provides a mayenite compound characterized by comprising enclosing electron and H?, a multifunctional agent characterized in that the agent contains at least one of the mayenite compound I and a mixture II of the mayenite compound enclosing electron and the mayenite compound enclosing H?, and exhibits radical scavenging activity, reducing property, deoxygenation performance, and dehydration performance; and a method for producing a mayenite-compound-containing product containing the aforementioned mayenite compound.

Abstract: An expansion valve used in an air conditioner having a passage for a liquid-phase refrigerant sent from a reservoir to a valve body, and a passage for a vapor-phase refrigerant after passing an evaporator 8. The refrigerant passage includes a valve chamber to control the amount of the refrigerant passing through the valve by means of a member configured to engage with a valve seat. The valve member is operated by a valve driving rod which can move in the axial direction in response to the temperature and pressure of the vapor-phase refrigerant. An orifice is interposed between a liquid-phase refrigerant inlet port and the valve chamber to decrease that bubbles contained in the refrigerant entering into the valve chamber by means of its throttling hole. Also the passage from the valve chamber to the valve seat is tapered to prevent collapse of bubbles.
