    摘要: An image pickup apparatus includes a system controller and a face detector, and can register face data of a photographer for a self-timer shooting mode in advance. In the self-timer shooting mode, the face detector extracts face data of people in a subject field from an image signal. When the system controller determines, on the basis of the extracted face data and the registered face data, that the photographer can be detected, the apparatus starts countdown for automatic shooting. Consequently, the apparatus can pick up an image of the photographer without fail, and the photographer can securely strike a pose within the countdown period of time. Furthermore, the apparatus can determine the countdown period of time optionally, thereby enabling the self-timer shooting to be executed depending on the personality of the photographer.

    摘要: An internal combustion engine includes a connecting rod that connects a crankpin and a piston. The connecting rod has first and second connecting rods, and a guide piston is disposed at a connecting portion between the first and second connecting rods. Deformed portions are formed on a lower end portion of a guide piston and on a balancer weight portion of a crankshaft in order to reduce the whole length of the connecting rod, whereby a bottom dead center of the guide piston is set to a lower position. The engine has improved thermal efficiency by reducing the distance between the crank portion and the piston, increasing the speed of behavior of the piston at a position near a top dead center to reduce thermal energy loss, and preventing generation of knocking.

    摘要: An optical transmitter outputs WDM signal lights comprising signal lights with 100 wavelengths of 10 Gbit/s, onto an optical transmission fiber. In the optical transmission line, a transmission fiber and a local area dispersion compensation fiber are disposed per repeater span defined by an optical amplification repeater, the local area dispersion compensation fiber is for compensating the average chromatic dispersion in the repeater span to become 2 ps/nm/km as well as a dispersion slope to become zero, and a wide area dispersion compensation fiber for compensating the average chromatic dispersion to become −0.2 ps/nm/km as well as the dispersion slope to become zero is disposed per predetermined number of optical repeater spans. The optical transmission fiber comprises a single mode optical fiber with large core diameter having a zero dispersion wavelength at a 1.3 &mgr;m band and plus chromatic dispersion at a signal wavelength band (a 1.55 &mgr;m band). The optical amplification repeater comprises an erbium-doped optical fiber to be pumped by a 0.98 &mgr;m band pumping light.
