    • An optical directional coupler of the invention has a first surface which is formed at the one end of a first or second graded index type light transmission body and which is perpendicular to the optical axis of the light transmission body, and also has a plurality of second surfaces which are formed at parts of the one end of the light transmission body which are different from the first surface. The light which is transmitted from a first optical fiber through the first surface is further transmitted through the second light transmission body, and then becomes incident on a second optical fiber. The light which is transmitted from the first optical fiber through the second surfaces is further transmitted through the second light transmission body and then becomes incident on a plurality of third optical fibers.

    • An optical disk device includes a DPDTE signal generating section that detects misalignment between a light spot and a mark or a pit, an FE signal generating section, an optical crosstalk correcting section which corrects a signal output by the FE signal generating section using the DPDTE signal generating section, and a focus control section which controls an actuator so that a light beam converges on an information layer. The DPDTE signal generating section detects the misalignment on the basis of phase information obtained from signals received from predetermined light receiving areas. The optical crosstalk correcting section performs a correcting operation of removing a signal component from predetermined receiving areas of a detector which component is used for a DPDTE signal, the signal component being contained in the signals from the predetermined light receiving areas of the detector which signals are used by the FE signal generating section.

    • In an ultrasonic washer for washing by splaying washing toward an object to be washed or a portion to be washed from a front end of a nozzle, a part of an ultrasonic wave propagation member connected to an ultrasonic transducer is protruded into a cavity of the nozzle into which the washing is filled in order to propagate ultrasonic vibration generated by the ultrasonic transducer to the washing efficiently. Furthermore, the ultrasonic wave propagation member is formed so that a cross-sectional area becomes gradually smaller as approaching to the front end thereof, so that the ultrasonic vibration is converged to the end face of the ultrasonic wave propagation member. Still furthermore, a length of the ultrasonic transducer and the ultrasonic wave propagation member is made to be integral multiplication of a half-wavelength of ultrasonic standing wave oscillation, and the end face of the ultrasonic wave propagation member from which the ultrasonic wave is emitted to the washing is disposed at a position of antinode of the ultrasonic standing wave oscillation where the amplitude becomes the largest.
