A telephone apparatus includes: a call signal detecting unit that detects a call signal transmitted via a public telephone line; an identification information detecting unit that detects source identification information transmitted via the public telephone line; and a source identification information detection control unit that controls an operation of the identification information detecting unit. The source identification information detection control unit actuates the identification information detecting unit when the call signal detecting unit detects the call signal and a predetermined condition is satisfied, and stops or does not actuate the identification information detecting unit when the call signal detecting unit detects the call signal and the predetermined condition is not satisfied.

A device includes a facsimile circuit, a voltage detector, an open-circuit voltage detector, and a telephone status monitoring unit. If a first voltage difference is less than a predetermined voltage difference, the monitoring unit judges that the public line is released if a second voltage difference is less than the predetermined difference, and that the public line is closed if the second difference is not less than the predetermined difference. If, when the facsimile circuit has released the public line, the first difference is not less than the predetermined difference, the monitoring unit judges that the public line is released if the second difference is less than the predetermined difference or if the detected line voltage equals the open-circuit voltage, and that the public line is closed if the second difference is not less than the predetermined difference and if the detected line voltage is different from the open-circuit voltage.

Provided is an epoxy resin composition for fiber-reinforced composite materials, which serves as a matrix resin composition for use in a self-adhesive prepreg for a face sheet of a honeycomb panel. The epoxy resin composition enables to increase self-adhesiveness of the prepreg, while improving workability and appearance quality of the prepreg. The epoxy resin composition is characterized by containing an epoxy resin (A) which is in a liquid state at room temperature; a thermoplastic resin (B) which dissolves in the epoxy resin (A) at a temperature not less than 90° C.; thermosetting resin particles (C) which do not completely dissolve in the epoxy resin (A) at a temperature less than 90° C. and has a softening point of not less than 120° C.; and a curing agent (D).

A method of correcting temperature characteristic of a rotation angle detecting device that includes a permanent magnet, a magnetic core, a Hall element that rotates relative to the permanent magnet when a rotating object rotates to provide an output signal. The method includes a step of setting temperature correction values for correcting a temperature characteristic of the rotation angle detecting device according to magnetic flux density. The magnetic flux density is divided into a plurality of grade ranges and the temperature correction values are respectively set for the grade ranges.

A headset of the present invention includes: a housing 10 worn on one auricle of a wearer; an arm 41 having a predetermined length, one end side of which is accommodated in the housing and the other end side of which is pulled out of a hole 13a of the housing to the outside, accommodated in the housing by adjusting the length pulled out of the hole 13a of the housing to the outside; and a microphone attached to the arm 41. When the headset is being used, the end of the arm 41 comes close to the wearer's mouth by pulling the arm 41 out of the housing 10. When the microphone need not be used, the arm 41 is stored in the housing 10 so as not to protrude from the housing 10.
