20120081847 | SOCKET FOR HOLDING ELECTRONIC DEVICE AND FLAME SENSOR - A case is provided for holding an ultraviolet detecting device in a state wherein an electrode-side terminal portion of the ultraviolet detecting device is inserted into one end portion. A conducting portion is provided connected on one end to an electrode terminal portion of the ultraviolet detecting device with the other end led out from the other end portion of the case. A sealing member is provided attached removably to the case. The sealing member seals airtight between the inside and the outside of the case in a state wherein a cable of the conducting portion passes therethrough. | 04-05-2012 |
20120083168 | SOCKET FOR HOLDING ELECTRONIC DEVICE AND FLAME SENSOR - A recessed portion is provided into which an ultraviolet detecting device is inserted, and a case is provided for holding removably in the state wherein the ultraviolet detecting device is inserted into the recessed portion. A conducting portion is provided that is connected on one end to the electrode portion of the ultraviolet detecting device and wherein the other end is led out from the case. The recessed portion is provided with first through fourth protrusions which insert into grooves that are formed in the ultraviolet detecting device. | 04-05-2012 |
20130256548 | REFLECTING MEMBER AND FLAME SENSOR - A reflecting member made from a tube-shaped member has an inner peripheral surface that structures a reflecting surface on an axis of the tube-shaped member. A slope, relative to the axis, of a tangent line of the inner peripheral surface in a cross-sectional plane containing the axis changes monotonically along the axis. In relation to a target facing a smaller opening of the tube-shaped member, at a specific distance therefrom, and having a flat region perpendicular to the axis and axially symmetrical relative to the axis, of an electromagnetic radiation incident along the axis from a larger opening of the tube-shaped member, that radiation reflected at a specific location on the larger opening side is incident on one end side of the flat region, and that radiation reflected at a specific location on the smaller opening side is incident on the other end side of the flat region. | 10-03-2013 |
