摘要： A cramping device for connecting two wires includes a housing having generally cylindrical slots which are parallel to and spaced apart from each other. A branch wire, terminates in one slot, and a main wire, which extends through the housing, is in the other slot. A retaining hole is provided into which the end portion of the branch wire is placed. Since the hole is at an angle to the slot, the branch wire is bent when the adjacent portion is placed in the slot. The bend assists in retaining the branch wire in its slot when it is forced against a contact which fits transversely across the slots, penetrates the insulation on the wires, and makes electrical contact therebetween. The slots may have narrowed portions near their outer edges to aid in retaining the wires in position. Preferably, a cover is provided which can enclose the housing. The cover and housing can be locked in a partially mounted position and a fully mounted position. In the former case, the pressing section of the cover retains the wires adjacent the upper edges of the slots; in the latter case, it forces the wires into the slots and against the connector to provide the electrical contact.
摘要翻译：用于连接两根电线的夹紧装置包括具有平行于并彼此分开的大致圆柱形槽的壳体。分支线终止于一个槽，并且延伸穿过壳体的主线在另一个槽中。设置有分支线的端部所在的保持孔。由于孔与槽成角度，当相邻部分放置在槽中时，分支线弯曲。弯曲有助于将分支线保持在其槽中，当其被迫靠在横向穿过狭槽的横向接触的触头时，穿过导线上的绝缘层并且在其间形成电接触。槽可以在其外边缘附近具有变窄的部分，以帮助将线保持在适当位置。优选地，提供可以包围壳体的盖。盖和外壳可以锁定在部分安装的位置和完全安装的位置。在前一种情况下，盖的按压部分将导线保持在狭槽的上边缘附近; 在后一种情况下，它迫使电线进入狭槽并抵靠连接器以提供电接触。

摘要： A constant travel speed control apparatus is for use in a vehicle and utilizes time delay control which is a kind of adaptive control for estimating an unknown term. A plurality of targeted paths, each having a certain waveform, for causing the actual speed of the vehicle to converge on a target speed are provided and an error vector is defined on the basis of the paths. The actual speed of the vehicle can be made to converge on the target speed thereof with a constant convergence performance along a target path in spite of the fluctuation of vehicle dynamic characteristics.

摘要： Methods and apparatuses are disclosed for improving accuracy of recording and reproducing information onto and from a magneto-optic recording information medium. In the first method, a width of a mark formed by a relatively low intensity light beam between two kinds of light beam intensities used for recording information is made larger than a sum of a track land width and the maximum track offset of the light beam, thereby the mark formed by the relatively low intensity light beam covers the track land portion in its full width. In the first apparatus, a reflected light beam from the magneto-optic recording information medium is split into a reflected beam for information reproducing and a reflected beam for tracking and focusing servos at the reproducing, thereby the apparatus can remove part being affected by the track groove portion from the reflected light beam for information reproducing. In the second method and apparatus, an intensity ratio of the two kinds of intensities of light beams used for information recording is controlled in such a manner that a mark width formed by the relative low intensity light beam is wider than a mark width formed by the relative high intensity light beam.

摘要： An optical disc having a plurality of information tracks, each information track having a servo field including a pair of wobbled pits and a clock pit. The distance between one of the wobbled pits and the clock pit in each servo field is selected such that the optical disc includes at least three different types of servo field.
