    • A system for displaying a color picture. This system has a field sequential signal generator for receiving and storing a color picture signal, which includes a plurality of signal components per field, at a first rate and sequentially sending the plurality of signal components, as a field sequential signal, at a second rate which is higher than the first rate; a picture display for displaying a monochromatic picture based on each of the signal components; a coloring device for coloring light emitted from the monochromatic picture displayed on the picture display; and a controller for sending a vertical sync signal, which includes a plurality of vertical sync pulses corresponding to the signal components respectively, to the picture display. The controller controls a timing at which each of the vertical sync pulses is sent to the picture display in such a way that respective time intervals between when the vertical sync pulse is sent from the controller to the picture display and when the signal component is sent from the field sequential signal generator to the picture display are equal.

    • Disclosed is a method of producing a grinding wheel by electroplating. A part of the outer peripheral portion of a grinding wheel body is immersed in a plating solution. While rotating the grinding wheel body at a low speed, electric current is supplied to flow between an anode disposed in the plating solution and a cathode contacting the grinding wheel body, so that a pre-plating layer of uniform thickness is formed on the outer peripheral surface of the grinding wheel body. Plating operation is continued while adhering abrasive grains to the pre-plating layer to further cause a precipitation of a plating layer to temporarily fix the abrasive grains. The abrasive grains are then pressed by a pressing roller so as to be forcibly embedded into the pre-plating layer by making an effective use of plastic deformation of the pre-plating layer, thereby to obtain a uniform projection height of the abrasive grains from the surface of the grinding wheel. Then, a final plating is conducted to finally fix the abrasive grains. Disclosed also is an apparatus suitable for use in carrying out this method.
    • 公开了通过电镀制造砂轮的方法。 研磨轮体的外周部的一部分浸渍在电镀液中。 在低速旋转砂轮体的同时,供给电流以在布置在电镀溶液中的阳极与接触砂轮主体的阴极之间流动,从而在外周形成均匀厚度的预镀层 磨轮表面。 在将磨粒粘附到预镀层上的同时继续进行电镀操作,以进一步引起镀层的沉淀以暂时固定磨粒。 然后通过加压辊压制磨粒,通过有效地利用预镀层的塑性变形将其强制地嵌入到预镀层中,从而获得磨粒的均匀突出高度 砂轮表面。 然后进行最终电镀以最终固定磨粒。 还公开了适用于实施该方法的装置。
