摘要： To provide a wheel steering apparatus capable of exhibiting a stabilized vehicle steerability without transmitting an external disturbance torque to a motor rotor even when the wheel receives an axially acting external force, this wheel steering apparatus includes a reciprocatingly movable rod 3 drivingly connected with a support member 2 for steerably supporting a wheel 1, and a ball screw mechanism 5 for reciprocatingly moving the rod 3 in response to rotation of a drive motor 4. In a rotational transmission system for transmitting rotation of the drive motor 4 to a nut member 5b of the ball screw mechanism 5, a clutch assembly 6 defining a reverse input limiting means is provided for preventing a rotar of the drive motor 4 from being rotated by the external force acting on the wheel 1. This clutch assembly 6 used is of a design wherein although rotation can be transmitted from an input shaft to an output shaft, no rotation is transmitted from the output shaft to the input shaft.

摘要： As the semiconductor chip is large-sized, highly integrated and speeded up, it becomes difficult to pack the semiconductor chip together with leads in a package. In view of this difficulty, there has been adopted the package structure called the "Lead-On-Chip" or "Chip-On-Lead" structure in which the semiconductor and the leads are stacked and packed. In the package of this structure, according to the present invention, the gap between the leading end portions of the inner leads and the semiconductor chip is made wider than that between the inner lead portions except the leading end portions and the semiconductor chip thereby to reduce the stray capacity, to improve the signal transmission rate and to reduce the electrical noises.

摘要翻译： 由于半导体芯片尺寸大，高集成度和加速度，所以难以将半导体芯片与包装中的引线组合在一起。 鉴于这种困难，已经采用称为半导体和引线堆叠和封装的称为“片上引线”或“引线芯片”结构的封装结构。 在该结构的封装中，根据本发明，内引线和半导体芯片的前端部之间的间隙比除引导端部和半导体芯片之外的内引线部分之间的间隙宽，从而减小 杂散容量，提高信号传输速率和减少电气噪声。

摘要： A semiconductor plastic package, more particularly a preferred package structure and method for making a BGA package. A resin sealed BGA package where a supporting frame which fixedly supports semiconductor parts; i.e., an IC chip, a circuit board, or a circuit film, is sealed with resin, using a mold which is composed of an upper mold half and a lower mold half with the lower mold half having a plurality of projections, one at a position corresponding to each of the external terminals. The mold has a divisional structure which has an air vent between the divisional elements thereof.

摘要： A measuring device for enabling an evaluation of a moldability of a thermosetting resin by determination of parameters suitable for high accuracy forecasting of flow and curing behaviors of the thermosetting resin within a metal mold, as well as a metal mold for molding a thermosetting resin and method for constructing runners of the metal mold which is effective to minimize if not prevent the occurrence of false in moldings. By utilizing unique or peculiar parameters of the thermosetting resin which are not influenced by a molding condition and by conducting a flow simulation with a metal mold having a flow passage of arbitrary dimensions using the determined values for the parameters, a forecasting of a flow in an actual metal mold is enabled so as to preselect optimum molding conditions and flow passage dimensions for a metal mold.
