    • The mirror-finished silicon surface is brought for pre-processing into contact with the hydrofluoric acid solution, it is NH cleansed, and then it is filmed by oxidation. Otherwise, the silicon surface not mirror-finished is brought for pre-processing into contact with the hydrofluoric acid solution, it is subject to an alkali etching {by a solution of KOH:H.sub.2 O base, NaOH:H.sub.2 O base, NH.sub.4 OH:H.sub.2 O base, or �NH.sub.2 (CH.sub.2).sub.2 NH.sub.2 !:H.sub.2 O:�C.sub.6 H.sub.4 (OH).sub.2 !base}, it is NH cleansed by the solution of (NH.sub.4 OH:H.sub.2 O.sub.2 base or NH.sub.4 OH:H.sub.2 O.sub.2 :H.sub.2 O base), and then it is filmed by oxidation. In such manufacturing methods the ornamental silicon articles may be processed to their final shape thereafter effecting an oxidation filming. Thus, without using a coloring agent the silicon surface is colored to provide ornamental silicon articles having excellent ornamental properties.

    • A hydraulic power generating device includes a main body case forming a flow passage provided with a water wheel chamber between a fluid inlet port and a fluid outlet port, a cover covering the main body case, a water wheel for power generation disposed in the water wheel chamber, a rotor magnet for rotating in cooperation with the water wheel. An ejection port including a groove is formed on the main body case for ejecting fluid toward the blades of the water wheel at a high speed and an protrusion part is formed on the cover for adjusting the aperture area of the ejection port by entering into the groove. Further, a discharge space is formed at a downstream position of the water wheel chamber so as to be in communication with the fluid outlet port, to which fluid after having rotated the water wheel is ejected and a stagnation preventing protrusion part is formed in the discharge space to facilitate flow of air bubbles to the fluid outlet port.

    • An automatic ice making machine 1 includes an ice tray 2 for making ice cubes, ice separating means 5 for separating ice cubes from the ice tray 2 by turning the ice tray 2, and an ice storage container for storing separated ice cubes. A stepping motor 13 is used for a drive source for the driver unit 5. The automatic ice making machine further includes detecting means for detecting a predetermined position of the ice tray 2; and control means for controlling a drive of the stepping motor 13. When the ice tray 2 is returned to the water supply position, the control means determines a predetermined position of the ice tray 2 by use of a signal from the detecting means, and determines other positions of the ice tray 2 by the utilization of the number of steps of the motor counted from the predetermined position. When the ice tray 2 is returned to the water supply position, the control means turns the ice tray 2 beyond the ice making position and the water supply position in the opposite direction to the ice separation position, and then turns the ice tray 2 toward the ice separation position and returns the ice tray 2 to the water supply position. Therefore, the amount of water to the ice tray 2 is increased.
    • 自动制冰机1包括用于制冰的冰盘2,用于通过转动冰盘2从冰托盘2分离冰块的冰分离装置5和用于存储分离的冰块的储冰容器。 步进电机13用于驱动器单元5的驱动源。自动制冰机还包括用于检测冰盘2的预定位置的检测装置; 以及用于控制步进电动机13的驱动的控制装置。当冰盘2返回到供水位置时,控制装置通过使用来自检测装置的信号来确定冰盘2的预定位置,并且确定 通过利用从预定位置计数的电动机的步数,冰盘2的其它位置。 当冰盘2返回到供水位置时,控制装置将冰盘2超过制冰位置和供水位置与冰分离位置相反的方向转动,然后将冰盘2朝向 冰分离位置,并将冰盘2返回到供水位置。 因此,向冰盘2的水量增加。
