An imaging apparatus includes an image unit, a video recording medium configured to store video data generated by the imaging unit, and a controller configured to control recording of the video data in the video recording medium. The video recording medium includes a first recording medium having a data area in which data can be recorded, and at least one second recording medium having first and second data areas in which data can be recorded. The second data area can be written data at a higher speed than a speed for writing data in the first data area. The controller records video data and management data for managing the video data in the first recording medium, using whole data area of the first recording medium. The controller records video data in the second recording medium, using only the second data area of the second recording medium.

The objective is to provide a high-pressure treatment apparatus with which the pressure or temperature in a treatment chamber can be efficiently adjusted in a short period of time without an overall significant increase in the size or complication of the apparatus. The high-pressure treatment apparatus has a pressure-resistant container having pressure-resistant walls surrounding a treatment chamber, a lid member that closes an open end of the pressure-resistant container, a supply means that supplies a process fluid into the treatment chamber, a partition wall that is thinner than the pressure-resistant wall and is provided along the inside surface of said pressure-resistant container to form a partitioned chamber with said inside surface, and a heat transfer control means. Said heat transfer control means controls heat transfer between said treatment chamber and said partitioned chamber by heating or cooling a heating medium outside the container and feeding said heating medium into said partitioned chamber.

A system and method for performing ranging and positioning as follows by using the procedure for packet transmission and reception between a sender and a recipient. A first radio set transmits packets to a second radio set as a recipient. The second radio set returns the packets without fail after the lapse of time (from the detection of packets) which corresponds to an integral multiple of a prescribed unit time. The first radio set counts, by using its counter, the time which has elapsed from its transmission of packets to its detection of packets from the second radio set. The remainder of the thus counted time after subtraction of the time taken by the second radio set from packet detection to packet return and the processing time of the first radio set itself is converted into the distance of propagation between the first radio set and the second radio set as a recipient.

摘要:
A transferring apparatus transfers an article to be processed, which is carried by a carrier device, to a holder provided in a processing chamber defined by a processing vessel and adapted to hold the article at a specified processing position. The transferring apparatus includes a temporarily holding member, and transfers the article from the intermediate position to the processing position after receiving the article carried by the carrier device at an intermediate position distanced from the holder and temporarily holding it. The temporarily holding member is retracted to a position in the outside of the processing vessel after the article is transferred.

摘要:
For the purpose of efficient transmission based on the UWB system, first and second baseband waveforms are generated at a cycle equivalent to an integral multiple of a carrier to have a specified phase difference from each other. The first baseband waveform is multiplied by the carrier and a first transmission data sequence to acquire a first transmission waveform. The second baseband waveform is multiplied by a phase shifted carrier and a second transmission data sequence to acquire a second transmission waveform. The first transmission waveform is mixed with the second transmission waveform to acquire a transmission signal. The transmission signal is transmitted as a π/2 shift BPSK signal to transmit a UWB signal. Selecting the baseband waveforms and the carrier makes it possible to configure the transmission band and easily provide division multiplexing transmission.
