    摘要： When communications of the same data are performed using a multi-carrier modulation method between a plurality of base stations and a mobile station at the same time and with the same frequency, a standing wave interference is generated to lower the carrier electric field level and the bit error rate is increased if the mobile station is located in an area where the reception powers of the electric waves from the base stations are almost identical. In order to prevent this, phase differences are set between the sub-carriers at the base station so as to enable the mobile station to avoid a situation in which all the sub-carriers are mutually cancelled. Thus, it is possible to easily correct an error, thereby improving the quality of communication.

    摘要： A DC-DC converter switches a semiconductor switch device for converting a DC voltage to a certain level and supplies the converted DC voltage to a load. The DC-DC converter is configured to be able to switch between a first feedback control mode and a second feedback control mode. The DC-DC converter selects the second feedback control mode when a load current flowing through the load is below a predetermined value. The DC-DC converter selects the first feedback control mode when a level of the DC voltage supplied to the load changes irrespective of a value of the load current.

    摘要： A photo film cassette contains a photo film, which is exited from a cassette shell when a spool is rotated in an unwinding direction. A data disk is integrally rotatable with the spool. The spool, if the photo film is unexposed, is stopped in an unexposed position with the bar code portion located in a first opening and with the quiet zone located in a second opening. The spool, if the photo film is partially exposed, all exposed or developed, is stopped in one of other predetermined positions. In a camera at first, a spool drive shaft is set in a reference position. To discern a used status of the cassette, after the camera is loaded with the cassette, the spool drive shaft is rotated in reverse to the unwinding. The spool drive shaft is engaged with the spool being in the initial position, to rotate the spool further. While the spool is rotated, the black and white bars and the quiet zone are detected with two photo sensors respectively through the first and second openings. As per a signal from the first photo sensor, it is determined whether the used status of the cassette is an unexposed status of the photo film. If the used status of the cassette is determined different from the unexposed status, then either one is determined between a partially exposed status and an exposed or developed status of the photo film as per a signal from the second photo sensor.

    摘要： A film magazine includes a spool which is supported for rotation in a magazine body and around which the roll film is wound, and a data disk which carries bar codes representing information inherent to the film magazine such as the ISO sensitivity, the number of exposure frames and the like of the film and is rotated together with the spool. The spool is held in a predetermined position when the film is completely in the magazine body so that the angular position of the spool relative to the magazine body represents the condition of use of the film. A photosensor is disposed in a fixed position to read the bar codes while rotating the spool and the condition of use of the film is distinguished on the basis of an angle by which the spool is rotated by the time the photosensor reads a predetermined particular point on the bar codes.

    摘要： For the solution growth, a solvent is used which is composed of a mixture of an oxide containing at least one member of those elements which constitute the oxide crystal and a halide containing at least one member of those elements which constitute the oxide crystal. The process enables the temperature of crystal growth to be lowered to a significant extent, avoids inclusions such as impure anionic elements from getting intruded into the oxide crystal, while retaining adequate crystal growth through solution growth, and affords, in spite of an atmospheric mode of crystal growth and with the pinning force of magnetic flux used to advantage, the same level of beneficial effects as in a mode of crystal growth at a low oxygen pressure.
