Abstract: A battery mounting (100) is provided for detachable placement in a device. The battery mounting (100) comprises a housing (104) for at least one battery cell (102), a clip (116) having a cammed surface (118) for cooperation with between the housing (104) and a portion of the device, a lock (130) with a-means for applying a force to the chip (116) for locking the battery mounting (100) in place in the device, and at least one power contact (138, 140) for connecting the at least one battery cell (102) to the device. The lock (138) provides a load in the engaging direction of the at least one power contact (138, 140).

Abstract: A battery mounting (100) is provided for use in a device from which the battery mounting (100) is detachable. The device has a board (101) with an opening (112) in which the battery mounting (100) is placeable and at least one power contact (138, 140) disposed on the cross-section of the board within the opening (112). The battery mounting (100) has a housing (104) for one or more battery cells (102). The battery mounting (100) also has a clip (116) having a cammed surface (118) for cooperation with a portion of the board (101) and a lock (130) with a means for applying a force to the clip (116) for locking the battery mounting (100) in place in the opening (112). The battery mounting (100) also has at least one power contact (132, 134) for connecting the battery cells (102) to the at least one power contact (138, 140) on the board (101), wherein the lock (130) provides a load in the engaging direction of the contacts (132, 134, 138, 140).

Abstract: Described is a flexible electrical assembly comprising a TAB device mounted on one surface of a flexible printed circuit board, a heat sink with a set of crimping members thereon mounted on an opposite surface of the printed circuit board and a protective cover with attachment holes therein positioned above the TAB device. The protective cover is mounted so that the holes are aligned with similar ones in the printed circuit board. The crimping members are inserted through the holes and are folded onto the protective cover to form a unified structure.

Abstract: An electro-optic display cell and method of making the same is disclosed herein. The display cell has an arrangement of display electrodes in contact with a liquid within a sealed enclosure. The enclosure comprises an impervious transparent cover and a rigid structural wall member. A seal between the cover and wall member and an elastomeric plug extending between the exterior and interior complete the enclosure. The cell is filled by injecting the liquid into the presealed enclosure by perforating the plug with hollow needles also employed to remove entrapped gas. Upon withdrawal of the needles the perforations collapse to self-seal the enclosure but for added integrity the plug is also mechanically clamped. The seal and plug can be formed as an integral elastomeric moulding around a frame member forming the side wall of the enclosure and the frame member clamped between the cover and a separate base.

Abstract: The sputter deposition of a thin film of material on both sides of a thin substrate is performed by positioning the substrate sides orthogonal to the target and preferably radial to the deposition center of the sputter system. The vapor deposition of alumina on a thin ferrite core for a magnetic head is accomplished by positioning the ferrite substrate in the vacuum chamber orthogonally to the target and radial to the particle deposition center. The alumina is deposited on both sides of the ferrite core simultaneously to substantially the same thickness. The deposition on both sides of the ferrite core protects the core against width erosion, and minimizes bending stress. In addition, signal output of the ferrite core when used in a magnetic head is increased.

Abstract: A magnetic head mount assembly for accessing data tracks recorded on a magnetic medium includes a mounting post, an arm element which engages the post, and a yoke on which circuit elements are disposed. An end portion of the post is slotted to receive electrical leads for connection to the magnetic head, which is supported by an air bearing slider positioned over the slotted end portion. The arm element is preferably frustoconical to reduce mass and weight, thereby enhancing access time.

Abstract: In a recorder having a transducer with a gap which coacts with a flexible medium to record and/or reproduce data, an endless groove is positioned on the transducer to circumscribe the gap.
