摘要： In a disk cartridge, a round portion with a circular arc shape whose center substantially coincides with that of a disk is formed at the forefront edge of the disk cartridge in the direction of insertion into a disk drive unit, and the remaining portion is a rectangular shape. The round portion preferably is formed so as to be decreased gradually in thickness toward its leading end. On the other hand, part of the components of the disk drive unit is arranged in an open space at corner portions at the forefront of the disk cartridge. A space in the disk drive unit thus can be utilized efficiently, whereby a small, thin disk drive unit having excellent operability and a disk cartridge permitting such a disk drive unit can be obtained.

摘要： A speaker system has an acoustic diaphragm and an image projection screen provided on a surface of the diaphragm integrally therewith so as to enable the user to enjoy both realistic image on the screen and powerful sound reproduced through the diaphragm. The rear surface of the diaphragm is closed at a peripheral portion thereof while the central portion of the rear surface of the diaphragm is opened to the exterior, so that the speaker system can provide a high level of reproduced sound pressure in low-pitched region, while the thickness of the speaker is reduced remarkably. The diaphgram can be driven by a plurality of driving units so that the speaker system can operate only with an ordinary stereophonic amplifier. The diaphragm can be composed of a pair of diaphragm elements capable of vibrating independently of each other and the screen may be integrally and commonly attached to the surfaces of these diaphragm elements in such a manner as to allow the diaphragm elements to vibrate independently of each other, whereby the speaker system can operate in stereophonic mode. Any variation in the acoustic characteristic attributable to variation in the condition of installation is compensated for by a change in the ratio of the opened area of the rear surface of the diaphragm to the whole effective vibration area or by a selective provision of a sound absorbing member on the rear side of the cabinet.

摘要： For a recording and playback optical head used for a dual layer disc, it is difficult to reduce the size and the cost due to the need to correct spherical aberration caused by a difference in thickness of a light-transmitting layer.A reflection mirror having a reflection surface on which light is reflected and provided with a member having ferromagnetism at the center, and a switching device that switches between a deformed state and a non-deformed state of the reflection mirror using a magnetic force are provided. The switching device includes a hard magnetic member, and a magnetizing member that magnetizes and demagnetizes the hard magnetic member. When light is concentrated on a first recording layer farther from the light-incident surface, the reflection mirror is used as a plane mirror, and when light is concentrated on a second recording layer closer to the light-incident surface, the reflection mirror is deformed in the shape of a concave surface by means of the switching device.

摘要： A scanning type image display apparatus including a light source, a frame buffer, a scanning mirror, a drive controller which outputs a drive signal to the scanning mirror, and a display controller which reads out pixel data from the frame buffer, generates display data for modulating an intensity of a laser beam using the readout pixel data, and causes the light source to emit an intensity-modulated laser beam based on the display data. The display controller calculates a scanning position of the laser beam on the display screen by the scanning mirror based on information relating to the drive signal inputted from the drive controller, reads out pixel data corresponding to the calculated scanning position on the display screen by executing a burst access to the frame buffer, and implements interpolation to generate the display data corresponding to the scanning position of the laser beam on the display screen.
