Abstract: According to one embodiment, a high-frequency conversion circuit includes a conductor posts, a transmission path, and a path cutoff unit. The conductor posts form a waveguide that guides the high-frequency signal. The transmission path mode-converts the high-frequency signal output from a semiconductor circuit chip and guides the same to the waveguide. The path cutoff unit cuts off the path of a high-frequency current generated when the high-frequency signal output from the semiconductor circuit chip is transmitted to the waveguide via the transmission path.

Abstract: 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.

Abstract: 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.
