    摘要: An optical pickup comprises an objective-lens driving device including a movable section provided with an objective lens, a focusing coil, and tracking coils, and a fixed section provided with a single magnetic circuit having a magnetic gap, the focusing coil and the tracking coils being disposed in the magnetic gap. The point of application of a tracking-driving force, the point of application of a result force of focusing-driving forces occurring in and outside the magnetic gap, and the position of the center of gravity of the movable section are made to substantially coincide with each other. In addition, the objective lens and the magnetic circuit are disposed within an area of a window in a lower shell of a optical disk. Further, a through hole for accommodating a lower portion of a yoke of the magnetic circuit is provided in a mounting base on which the objective-lens driving device is mounted. An inclining fulcrum and a height adjusting means for inclining the objective-lens driving device about the inclining fulcrum are provided in the vicinities of the through hole.

    摘要: The present invention provides a slot antenna in which the radiation toward the zenith direction is not obstructed although it is arranged on an upper side of a ground conducting plate. The antenna device 11 operates as the slot antenna by providing a slot 14 in an upper plate portion 13 of a shield case 12. The shield case 12 is provided on a ground conducting plate 20. The slot 14 is composed of a first aperture 15 extending in a straight line, a second aperture 16 communicating with one end of the longitudinal direction of the first aperture 15, and a third aperture 17 communicating with the other end of the longitudinal direction of the aperture 15. The apertures 16 and 17 have the same triangular shapes which are point-symmetrical to the center of the aperture 15. When the power is fed by a feeding pin 18 to excite the slot 14, the directions of the electric fields generated at the apertures 16 and 17 are inclined to the direction of the electric field generated at the aperture 15 and the electric fields of the apertures 16 and 17 cancel the electric field of the aperture 15.

    摘要: A single substrate hydrogen and microwave absorber (20) attenuates spurious microwave signals in a metal Integrated Microwave Assembly (10, 10′) and reduces hydrogen poisoning of hydrogen sensitive components implemented in the Integrated Microwave Assembly (10, 10′). The single substrate hydrogen and microwave absorber (20) includes a titanium substrate (30) with channels (32) spaced apart from one another by a predetermined distance. A layer of microwave absorbing material (34) is formed on portions (35) of the titanium substrate (30) between the channels (32), and a layer of hydrogen getting material (36) is formed in the channels (32) of the titanium substrate (30).
