摘要:
An AV data recording apparatus and an AV data recording method are provided, in which even in the case of using the UDF file system, seeking can be minimized. The AV data recording method has file management information for managing continuous blocks on a disk as an extent, and dividing the extent into groups so as to manage the extent as a file, wherein a new directory is created on a disk, and a not recorded but allocated extent is kept as a reservation region for recording file management information.

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 a fuel feed system is achieved.

An initialization method of the present invention is a method for initializing a material (variable-resistance material) (2) whose resistance value increases/decreases according to the polarity of an applied electric pulse. An electric pulse having a first polarity is applied at least once between first and second electrodes (1, 3) connected to the variable-resistance material (2) such that the potential of the first electrode is higher than that of the second electrode.
摘要:
An audio/video information recording/reproducing device capable of easily implementing a post-recording function on an optical disk by using even a low-cost disk drive having a comparatively low-speed seek time. When recording a video file, it is recorded on an optical disk continuously for a duration equivalent to more than three times a seek time. When recording dubbing audio, it is recorded continuously only with constant data size at the same time with the reproducing of the recorded video file, thereby enabling concurrent real-time continuous reproducing and recording. Accordingly, concurrent reproductions of a video file and an audio file are ensured when reproducing dubbing audio.

An information output apparatus is provided, which is capable of displaying past contents, current contents and future contents so that these past contents, current contents and future contents are seamlessly handled and clearly distinguished from each other for easy viewing. An information output apparatus (12) includes an output unit (1209) which arranges all or a part of past content information, current content information and future content information in two or more approximately concentric approximate circles and outputs these information in visually different display styles.
摘要:
A method for accessing an information recording medium in which a data area is allocated is provided. First file management information which provides a first access method and second file management information which provides a second access method are recorded in the information recording medium. The first file management information and the second file management information manage files recorded in the information recording medium. The method of the present invention comprises the steps of: (a) reading out one of the first file management information and the second file management information; and (b) accessing the data area with the access method provided by one of the read out first file management information and the read out second file management information.
摘要:
An FM signal demodulator has a phase shifter including transversal filters for producing from a FM video signal two FM video signals which are different in phase by 90.degree. from each other, and a demodulator for detecting phase information of the FM video signal, wherein the carrier frequency is at least quadrupled prior to demodulation so as to suppress components of the FM video signal not to be included in the demodulated video signal.
摘要:
A fuel tank for a fuel cell includes a fuel valve which allows a methanol water solution to pass to a fuel supply portion from a fuel injecting portion after joining a fuel cell main body and the fuel tank for the fuel cell, and shuts off the passage of the methanol water solution before the fuel supply portion and the fuel injecting portion are disconnected. Accordingly, the fuel valve is properly opened and closed, the liquid fuel does not leak out from the fuel tank for the fuel cell at a time of attaching and detaching, and it is possible to improve a safety in the fuel supply in comparison with the conventional structure.
摘要:
A radio-type transmitting device capable of transmitting information other than information in an internal memory is provided. A RFID tag includes a encoding circuit for digitalizing receiving sensitivity of a radio wave sent from an external transmitting/receiving apparatus and then sending the digitalized receiving sensitivity to the external transmitting/receiving apparatus. Thus, the external transmitting/receiving apparatus can obtain a distance between the external transmitting/receiving apparatus and the RFID tag based on received sensitivity information.
