摘要： A printer synchronization control for maintaining columnar alignment of dots printed by a dot matrix printer including a shuttle wherein the relative velocity between the paper and shuttle is non-uniform. Plural print elements are mounted on the shuttle for printing dots at preselected positions on the paper. A particular row and column arrangement of the dots defines a character. A counter measures the relative velocity between the paper and shuttle over a period of time inversely proportional to the relative velocity. A second counter determines the time at which an actuator must be triggered to cause a print element to strike the paper at a preselected columnar position to maintain columnar alignment of the dots in a character. Means are provided for causing the print element to strike the paper at the preselected columnar position as a function of the second counter. A third counter may be provided to enable two or more sets of the print elements to be actuated in time-staggered fashion to minimize peak current drain.
摘要翻译：一种打印机同步控制，用于维持由包括梭子的点阵打印机印刷的点的柱状对准，其中纸张和梭子之间的相对速度是不均匀的。多张打印元件安装在梭子上，用于在纸张上的预选位置打印点。点的特定行和列排列定义了一个字符。一个计数器测量纸张和梭子之间的相对速度在一段时间内与相对速度成反比。第二计数器确定致动器必须被触发以使打印元件在预选的柱状位置上打击纸张的时间，以维持点的字符对齐。提供了用于使打印元件作为第二计数器的函数在预选的柱状位置处打击纸张的装置。可以提供第三计数器以使得能够以时间交错的方式致动两组或更多组打印元件以最小化峰值电流消耗。

摘要： A locking mechanism of the present invention is for locking a cover to a body of an apparatus when the cover closes the body. The locking mechanism includes a strip-shaped portion having a free end portion and an engagement hole into which the free end portion projects when the cover is closed. The strip-shaped portion is formed on the cover and engages the body to resiliently deform when the cover is moved in a closing direction in which the cover closes the body. The strip-shaped portion engages the body to resiliently deform when the cover is moved in an opening direction in which the cover opens the body. The opening direction is opposite to the closing direction. The body has a portion defining an engagement hole into which the free end portion projects to engage the wall of the engagement hole when the cover closes the body, and from which the free end portion projects out of the engagement with the wall when the cover is moved in the opening direction.

摘要： A light-emitting element, or array of light-emitting elements, is formed by diffusion of an impurity into a semiconductor substrate, creating a light-emitting region. Following the diffusion, the surface zone of the light-emitting region, which includes crystal defects caused by the diffusion process, is removed by etching, thereby increasing the light-emitting efficiency by removing nonradiative recombination centers.

摘要： A positioner for precisely and quickly locating a magnetic head structure relative to a selected track on a disc file utilizes an electromagnetic device such as a brushless DC motor for pivoting a directly coupled arm and head mount through a small arc about a pivot axis. The motor, which may advantageously be mounted outside an hermetic enclosure for the discs and the arm and head structure of the positioner, comprises a multi-pole magnetic rotor whose mass is concentrated at the pivot axis, and whose periphery is closely encompassed by a stator. Energizing coils on the stator are wound in close magnetic coupling to the rotor to provide substantially uniform field distribution throughout the limited arc of movement of the rotor. While the masses of the rotor and an arm-coupling shaft are a substantial majority of the total mass of the positioner, the inertial components of the motor, shaft, and the positioner arm are well below the inertial components contributed by the head mount and heads at the terminus of the arm. Minute angular control at the motor pivot axis is feasibly translated into precise high speed accessing and tracking of selected locations on the discs. In addition, heat generated during high duty cycle energization of the motor is readily dissipated, and the motor is readily accessible for service and replacement without opening the dust-free hermetic enclosure.
