Abstract:
When a main body of a sensor chip (1) is in a grounded state, a shield layer (71) constituting a shield electrode formed on a circuit layer (72) is grounded through a resistor (46).
Abstract:
Provided is a pressure detection unit in which a waterproof property can be improved. In a pressure sensor, a sealing-resin portion is joined to an outside side surface of an element main body made of stainless steel, aluminum, or nickel such that the sealing-resin portion surrounds a plurality of lead pins. In the pressure sensor, a roughened annular surface portion is provided at a region where the sealing-resin portion is joined on an upper end surface of the element main body so as to be disposed in a manner to partition an external peripheral edge and an internal peripheral edge arranged at the outside side surface of an element main body in the sealing-resin portion.
Abstract:
In a refrigerant circuit component or valve device, the present invention projection-welds a connector to a cap member and prevents intrusion of spatter into a refrigerant circuit. A-cylinder section in which an inside hole of the connector is open is inserted in an inside hole formed in the center of the cap member. The area between the A-cylinder section and a projection of the connector is used as a spatter generation space. The projection of the connector abuts against the cap member and is projection-welded to form a welded part. The open end of the inside hole of the A-cylinder section is crimped to pressure-join the open end to the open end of the inside hole of the cap member. Spatter is sealed inside the spatter generation space. A portion of the surface layer to which the generated spatter adheres may be removed by machining to provide a spatter-removed structure.
