    • The object of the invention is to provide a method for molding a resin-molded article having an excellent surface appearance without any resin-intrusion part on the front surface of a skin thereof. In the invention, the skin is placed on a part of a inner wall of a mold and then injecting a synthetic resin into a cavity of the mold to effect an integral molding of a resin-molded article having the skin on a part thereof, wherein a mold having a first gate on a first inner wall part located on the part other than the back surface of the skin placed on the inner wall of said mold and a second gate on a second inner wall part which faces the back surface of the skin placed on the inner wall is employed; and wherein the synthetic resin is first injected from said first gate until the tip portion of the synthetic resin comes close to the edge of said skin, and then the synthetic resin is injected from the second gate.

    • In order to enhance the fatigue resistance and the anti-seizure property while maintaining the embeddability, there is provided a plain bearing comprising a bearing alloy layer, an intermediate layer and an overlay layer sequentially formed on the inner surface of a back metal. The inner surface of the bearing alloy layer is provided with a recess “a” and protrusions “b”, thereby being made into a textured uneven surface. The protrusion has the shape of a oblique square at 45° relating to the circumferential direction, so that when a foreign particle X introduced between sliding surfaces of a shaft and the plain bearing is moved in the circumferential direction in accordance with the rotation of the shaft, the foreign particle X runs against a side edge of the protrusion “b” and moves along the side edge, thereby the embedding of the foreign particle X is promoted. If the foreign particle fails to be adequately embedded, the foreign particle leaves the side edge again.
    • 为了在保持嵌入性的同时提高耐疲劳性和抗咬合性,提供了一种滑动轴承,其包括依次形成在背面金属的内表面上的轴承合金层,中间层和覆盖层。 轴承合金层的内表面设置有凹部“a”和凸起“b”,从而形成纹理不均匀的表面。 突出部具有与圆周方向成45度角的倾斜方形的形状,使得当轴的滑动面和滑动轴承之间引入的异物X沿着轴的旋转沿圆周方向移动时 ,异物X相对于突起“b”的侧边缘延伸并且沿着侧边缘移动,从而促进了异物X的嵌入。 如果外来颗粒不能充分地嵌入,则外来颗粒再次离开侧边缘。

    • Disclosed are a bump stopper and a manufacturing method therefor which can maintain the shock-absorbing characteristics and durability performance constantly for a prolonged period of time regardless of the temperature or humidity of the usage environment, which can maintain a constant dimensional precision for a finished product, which is excellent in material yield rate and manufacturing efficiency, and which is low-cost, lightweight, recyclable, and ecological. A bump stopper (1) is provided in the vicinity of a rod of a shock absorber to elastically limit the stroke of the shock absorber at the time of the contraction thereof and to absorb the shock generated at that time. The bump stopper includes a hollow cylindrical bellows part (11) which extends along a stroke direction S of the shock absorber. The bellows part is formed by thinning thermoplastic resin and is constructed such that first parts (12) which are bulged outward and second parts (13) which are recessed inward are provided alternately and repeatedly in the stroke direction S.

    • A cache system which, when a cache is a bus master, puts a CPU in a standby state and makes effective a signal common to the CPU and cache and a signal decided only by the cache, or when the CPU is the bus master, makes effective the signal common to the CPU and cache and the signal decided only by the CPU, or when at a cache miss, the cache gives the CPU a control signal requesting reexecution of memory access and a control signal to allow the memory system to accept memory access to thereby operate the cache dependently on the CPU, so that even when either the CPU or the cache is the bus master, signal transmit-receive with respect to the memory system is adapted to be carried out substantially at the same timing. Furthermore, where a cache miss occurs when the CPU accesses to single data, and in order to cope with the case that a plurality of data from the memory system to the cache are transferred, the data of address next to the accessed address by the CPU is initially transferred from the memory system to the CPU, thereafter data is transferred to the CPU while changing the address in a so-called round robin method, and at last the object data for the CPU is controlled to be transferred in parallel to the CPU and cache, thereby minimizing the number of times for data transfer from the memory system to the cache.
    • 一种缓存系统,当高速缓存是总线主机时,将CPU置于待机状态,并使CPU和高速缓存的公共信号和仅由高速缓存确定的信号有效,或者当CPU为总线主机时, 有效的CPU和高速缓存信号以及仅由CPU决定的信号,或者当高速缓存未命中时,高速缓存向CPU提供请求重新执行存储器访问的控制信号和控制信号以允许存储器系统接受存储器 访问从而依赖于CPU来操作高速缓存,使得即使CPU或高速缓存都是总线主机,相对于存储器系统的信号发送接收也适于基本上在相同的定时执行。 此外,当CPU访问单个数据时发生高速缓存未命中,并且为了应对来自存储器系统到高速缓存的多个数据的传送的情况,由CPU访问的地址的旁边的数据 最初从存储器系统传送到CPU,此后,以所谓的循环方式改变地址,将数据传送到CPU,最后控制CPU的对象数据并行传送到CPU 并缓存,从而最小化从存储器系统到高速缓存的数据传输的次数。
