摘要： A screen panel includes a rigid glass, a lenticular lens and a Fresnel lens laminated with each other, and the edges of the screen panel are sealed. An air evacuation path is formed between the lenses by wires inserted between the contact surfaces of the lenses, or by convexes or concaves previously formed on one of the contact surfaces. Because of the provision of the air evacuation path, the air between the lenses of the screen panel is sufficiently evacuated, and the lenses can closely attached to each other. Therefore, the flatness of the screen panel can be enhanced, and the degradation of the image quality can be prevented.
摘要翻译： 屏幕面板包括彼此层压的刚性玻璃，双凸透镜和菲涅耳透镜，并且屏幕面板的边缘被密封。 通过插入在透镜的接触表面之间的导线，或者通过预先形成在一个接触表面上的凸起或凹部，在透镜之间形成排气路径。 由于设置了排气路径，屏幕面板的透镜之间的空气被充分抽真空，并且透镜可以彼此紧密地相连。 因此，可以提高屏幕面板的平坦度，并且可以防止图像质量的劣化。

摘要： A disk cartridge having a case including a first planar protion and a second planar portion which are disposed opposite to each other with a given spacing therebetween, and a plurality of walls which join the first planar portion and the second planar portion together. The case contains an information carrying disk in a rotatable manner and has an opening formed in one of the walls through which the disk can be inserted or removed. The disk cartridge has a lid mounted on the case for opening or closing the opening. The lid is formed so that an outer surface of the lid is located inside an outer surface of the wall in which the opening is formed.

摘要： A turntable is a table mounted to a shaft (4) of a spindle motor and the turntable supports a laminated disc thereon and drives the disc in rotation. The laminated disc includes a lower disc and an upper disc stacked on the lower disc, and is supported on a disc-supporting surface. When the disc is loaded on the turntable, a fitting member fits into the center hole of the laminated disc for centering the laminated disc with respect to the shaft. The fitting member fits the center hole of the lower disc when the laminated disc is supported on said disc-supporting surface. The turntable may include a tapered member which guides the laminated disc to the disc-supporting surface. The laminated disc includes lower and upper discs each having an edge which defines the center hole. The corners of the edges are cut away along a circumference of the center hole. The upper and lower discs are placed together so that the cut-away corner directly face each other.

摘要： A rotary magnetic head device has a plurality of bobbins to which coils are respectively fixedly attached, and a place spring fixedly attached to the bobbins. The plate spring has a plurality of front ends to which magnetic heads are respectively fixed. The magnetic heads are held in such a manner that, when a current is selectively supplied to one or more of the coils, the respective one or more of the magnetic heads independently moves in the axial direction. A rotary magnetic head device has a head supporting base plate, and a head supporting table which is tilted by an angle with respect to the head supporting base plate. The tilt angle is adjusted by moving the head supporting table. In a rotary magnetic head device, the position in the axial direction of a magnetic head is detected, and the level of a current to be supplied to a coil is adjusted on the basis of the detection result.

摘要： In a magnetic recording/playback system having a magnetic head drive device for moving a movable head disposed within and mounted to a rotating upper drum in parallel with the axis of the drum, and a fixed drum supporting the upper drum so that the upper drum can rotate, an AC magnetic field generator is disposed along the peripheral surfaces of the drums at a location at which the magnetic tape is not wrapped on the drums. The AC magnetic field generator applies an AC magnetic field to the movable head that varies in the direction of the axis of the drums. Information on the position of the movable head is detected in accordance with the detection signal of the AC magnetic field derived by the movable head and the position of the movable head is controlled by feeding the detected positional infromation back to the magnetic head driving device.
