摘要:
A synchronization signal control circuit according to embodiments includes a phase difference detecting section and a vertical synchronization correction control section. When a vertical synchronization period of an input video signal is within a compensation period range between a minimum vertical synchronization period and a maximum vertical synchronization period, the synchronization signal control circuit outputs a display vertical synchronization signal used for displaying the input video signal to a display section capable of providing a display based on the input video signal. The phase difference detecting section detects a phase difference between an input vertical synchronization signal based on the input video signal and the display vertical synchronization signal. The vertical synchronization correction control section corrects the cycle period of the display vertical synchronization signal within the compensation period range so as to reduce the phase difference.

An antenna device includes a printed circuit board and an antenna element. The printed circuit board has a face a portion of which is formed by a conductive layer overlaid with a magnetic material layer made of anisotropic magnetic material. The magnetic material layer is arranged in such a way that a hard magnetization axis of the anisotropic magnetic material is directed almost parallel to the face. The antenna element is arranged almost parallel to the printed circuit board on a side of the face. The antenna element is arranged in such a way that an antenna current distributed on the antenna element if the antenna element is excited is directed almost perpendicular to the hard magnetization axis.

A method for manufacturing a centrifugal casting die includes the steps of supplying a first liquid agent for forming a backup layer to be releasably bonded to an inner surface of a cylindrical die, rotating the die body so that the first liquid agent is uniformly spread over the entirety of the inner surface of the die body, and curing the first liquid agent spread over the entirety of the inner surface of the die body to form the backup layer. A second liquid agent is applied to be bonded to be integral with an inner surface of the backup layer to form a top layer. Then the die body is rotated so that the second liquid agent is uniformly spread over the entirety of the inner surface of the backup layer and cured to form the top layer. The top layer releasably holds a centrifugally casting material supplied to the inner surface thereof.

A camera apparatus equipped with an optical system, a photographing element for converting a light signal of an object to be photographed from the optical system to an electric signal, an A/D conversion unit for converting the electric signal from the photographing element to digital image data, a data compression unit for compressing the image data from the A/D conversion unit with a prescribed form based on a software program. Data conversion converts the compressed data from the data compression unit to a prescribed form of data that is recordable into a direct read after write type optical disk or a rewritable optical disk that records the compressed data. The camera enables a user to watch on a personal computer static images that have been photographed without making data transfer to the personal computer.
