Abstract: An infrared apparatus includes a case, and an infrared device to input and/or output infrared rays. In the infrared apparatus in which the infrared device is received in the case, the case has an infrared transmitting window part which transmits only infrared light and which does not transmit visible light. Of a light transmitting resin through which near-infrared laser used for near-infrared laser welding passes and a light absorbing resin which emits heat and melts when receiving the near-infrared laser, the infrared transmitting window part is made of the light transmitting resin.

Abstract: A method for manufacturing a terminal includes: an electrically conductive member that has an electrical connection, which is formed at an end portion of the electrically conductive member; and a seal film that is formed on a surface of a intermediate portion of the electrically conductive member, which is other than the electrical connection. In the method for manufacturing, the electrically conductive member is formed by processing an end portion of a rounded rod, which has a cross section having an arcuate shape, into a planar shape to form the electrical connection. Furthermore, a liquid seal agent is coated on an intermediate portion of the rounded rod, which is other than the end portion. Then, the coated liquid seal agent is solidified to form the seal film.

Abstract: A method for manufacturing a terminal includes: an electrically conductive member that has electrical connections, which are respectively formed at end portions of the electrically conductive member, wherein the electrical connections are respectively connectable with a lead wire and a terminal of a Hall IC; and a seal film that is formed in a surface of an intermediate portion of the electrically conductive member. In the method for manufacturing, end portions of a planar rod having a rectangular cross section are respectively used as the electrical connections, and an intermediate portion of the planar rod is processed such that corners of the rectangular cross section are rounded. Thereafter, a liquid seal agent is coated on the intermediate portion. Furthermore, the coated liquid seal agent is solidified to form a seal film.

Abstract: A method for manufacturing a terminal includes: an electrically conductive member that has an electrical connection, which is formed at an end portion of the electrically conductive member; and a seal film that is formed in a surface of a predetermined portion of the electrically conductive member, which is other than the electrical connection. In the method for manufacturing, the electrically conductive member is formed by processing an end portion of a rounded rod, which has a cross section having an arcuate shape, into a planar shape to form the electrical connection. Furthermore, a liquid seal agent is coated on a predetermined portion of the rounded rod, which is other than the end portion. Then, the coated liquid seal agent is solidified to form the seal film.

Abstract: A temperature sensor includes a casing having a first part and a second part, a temperature detector for detecting temperature of fluid and a pair of outside wires connecting to the temperature detector. The casing further includes a mold portion and an insert portion. The mold portion is disposed in the first part of the casing. The insert portion is disposed in the second part of the casing, and includes a pair of holes for inserting the outside wires therein. The temperature detector is disposed in the first part of the casing. Each outside wire extends from the second part of the casing to an outside of the casing through the hole.
