摘要： The magnetic recording/reproducing apparatus for recording onto or reproducing from a magnetic tape housed in a cassette by using a rotary magnetic head has tape drawing-out means (6, 8, 9, 55) for winding a portion of the tape (53) between the two reels in the cassette around the rotary magnetic head (2) by a predetermined angle. The magnetic recording/reproducing apparatus has further tape driving means (3, 57) for feeding the magnetic tape at a constant speed, reel driving means (24) for driving either one of the two reels so as to take up the magnetic tape in the reel driven by the reel driving means, and braking means (18,19, 20) for braking the rotation of the reels. Each of the above described means is selectively actuated by a ring-shaped cam operating member (64) provided in the outer peripheral surface or the inner peripheral surface thereof with cam surfaces each for effecting the operation of the respective means in response to the mode of operation of the magnetic recording/reproducing apparatus. The selective operation is specifically determined by the rotational position of the ring-shaped cam operating member, and the rotational position is varied in response to the mode of operation. Detecting means (62, 72) for detecting the rotational positions is provided in the ring-shaped cam operating member.

摘要： A rotary cylinder device (1) for helical scan type magnetic recording/reproducing apparatus. The device comprises a rotary cylinder (2) having an axis of rotation and arranged to oppose a stationary cylinder (3) in the direction of the axis of rotation leaving a small gap (35) therebetween. The rotary cylinder has an end surface (2a) facing the stationary cylinder and an outer peripheral surface (2b), and recesses (11, 11') formed in the end surface (2a) and opening in the outer peripheral surface (2b) such as to extend therefrom radially inwardly over a small distance. Each of the recesses has a leading end wall (11b) and a trailing end wall (11a) as viewed in the direction of rotation of the rotary cylinder. The rotary head device further comprises magnetic heads (10, 10') fixed to the rotary cylinder and positioned in the recesses and having outer extremities projecting beyond the outer peripheral surface (2b) of the rotary cylinder. The distance between the leading end wall and the trailing end wall of each recess is progressively decreased towards the axis of rotation of the rotary cylinder such that the distance is greatest at the outer end of the recess adjacent the magnetic head and the smallest at the inner end of the recess remote from the magnetic head.

摘要： To achieve an expansion of color reproducibility and an improvement in contrast ratio, color filters 8R, 8G and 8B formed in stripes are successively arranged on one surface of a front glass substrate 1, interposing a black matrixes 7 between them. Sustaining electrodes 6 are provided thereon and a dielectric layer 9 and a protecting layer 10 are provided. On a rear glass substrate 2, barrier ribs 3 are provided in the manner they face the respective black matrixes 7, and thus the spaces between the barrier ribs 3 facing the respective color filters 8R, 8G and 8B form cells. The cells are respectively provided with the sustaining electrodes 6 falling at right angles with the address electrodes 4, coated with fluorescent substances 5R, 5G and 5B corresponding to the respective colors, and also sealed to hold discharge gas therein. A wave band selecting filter 11 for screening the light emitted from the discharge gas in the respective cells is provided on the other surface of the front glass substrate 1.
摘要翻译： 为了实现颜色再现性的扩展和对比度的提高，在前玻璃基板1的一个表面上依次布置条纹形成的滤色器8R，8G和8B，在它们之间插入黑色矩阵7。 在其上提供维持电极6，并提供介电层9和保护层10。 在背面玻璃基板2上，以与黑色矩阵7相对的方式设置有隔壁3，因此与各滤色器8R，8G，8B相对的隔壁3之间形成单元。 这些单元分别具有与寻址电极4垂直的维持电极6，涂有对应于各种颜色的荧光物质5R，5G和5B，并且还密封以将放电气体保持在其中。 在前面玻璃基板1的另一个表面上设置有用于对从各个单元中的放电气体发射的光进行屏蔽的波段选择滤波器11。

摘要： A locking device for a cover of a magnetic tape cartridge (3) for locking a pivotable cover (4) for covering magnetic tape inlet and outlet ports (16 and 17) of the magnetic tape cartridge, including a projection (70) formed on an arm (67) for pivotally supporting the pivotable cover which is engageable with an engaging claw section (74) of a locking member (73) which further includes an operation section (75) and a resilient section (76). The locking member is pivotally supported on a magnetic tape cartridge case (3) and urged by the biasing force of the resilient section to bring the engaging claw section into engagement with the projection. The operation section of the locking member is located in a position in which it is capable of cooperating with an unlocking pin moved from three directions, to thereby give latitude to the process for loading a magnetic tape cartridge on a magnetic recording and reproducing apparatus.
