A fuel cell body has an anode having an anode-side separator with projections and depressions formed on its surface, a cathode, and a membrane electrode assembly disposed between the anode and the cathode, and the fuel cell body is disposed in a container for storing liquid fuel so that at least the anode side is immersed therein. Fuel passageways through which the liquid fuel flows are formed by regions surrounded by the projections and depressions on the surface of the separator and the membrane electrode assembly. By this, the downsized, simplified and lower power consuming structure of auxiliary equipment such as fuel feed system is achieved.

An optical head device includes a light source (30) configured to emit a light beam, a light collecting optical system configured to converge the light beam onto an information recording medium (10), a hologram element (20) configured to diffract the light beam reflected from the information recording medium (10), and a photodetector (40) having a plurality of detection regions configured to receive the light beam diffracted by the hologram element (20). The hologram element (20) has two diffraction regions (261 and 262) separated from each other by a straight line (260) extending in a radial direction of the information recording medium (10). At least one of the two diffraction regions has a pattern which introduces coma aberration in the radial direction. The light diffracted by the diffraction region having the coma aberration has coma aberration in the radial direction.
摘要:
A method for DTMF transmission between different address systems in a communication system containing a first network (NW) 20A including an SIP terminal 41A connected to an SIP server 30A, a second network (NW) 20B including an SIP terminal 41B connected to an SIP server 30B, and an SIP converter 10 connecting the first and the second NWs. When the SIP converter 10 detects coded DTMF information from one of the NWs while a session is established between the SIP terminal 41A and the SIP terminal 41B, the SIP converter 10 determines whether the other of the NWs supports the coded DTMF information. If the other of the NWs does not support the coded DTMF information, the SIP converter 10 stores voice-data DTMF corresponding to the coded DTMF information into a payload of RTP and transfers the information to the SIP terminal of the other network.

摘要:
An optical pickup has a semiconductor laser, a diffractive optical element that has first diffraction regions and second diffraction regions and diffracts a beam emitted by the semiconductor laser, an objective lens that focuses the diffracted beam on an optical disc, and a detection unit that detects a tracking error signal using the diffracted beam reflected by the optical disc. When a zero order diffraction beam is focused on the optical disc, a first order diffraction beam is diffracted by the first diffraction regions to be focused at a position between the objective lens and the optical disc, and diffracted by the second diffraction regions to be focused at a position beyond the optical disc. The first order diffraction beam has a beam width that, on the optical disc in a radial direction thereof, is two times or greater a track pitch of the optical disc.
