    • In an indication hand type stopwatch energized by a battery having a second indication hand, a minute indication hand and an hour indication hand, a battery lifetime display has a battery lifetime detective section for monitoring a voltage of the battery and a battery lifetime display circuit means connected to the battery lifetime detective section and for controlling the driving of the minute indication hand serving as a battery lifetime indication hand for displaying a battery lifetime while the stopwatch is in a non-counting mode.In the case that the battery voltage is over the predetermined voltage, the minute indication is driven by 15 steps clockwise in response to the operation of an external operation switch and in the case that the battery voltage is below the predetermined voltage, the minute indication is driven by 3 steps.
    • 在由具有第二指示手,分指示手和小时指示手的电池供电的指示手型秒表中,电池寿命显示具有用于监视电池的电压的电池寿命检测部和电池寿命显示电路装置 连接到电池寿命检测部分,并且用于控制作为电池寿命指示手的微小指示手的驱动,以在秒表处于非计数模式时显示电池寿命。 在电池电压超过预定电压的情况下,响应于外部操作开关的操作,微小指示顺时针旋转15步,并且在电池电压低于预定电压的情况下,微小指示为 由3个步骤驱动。

    • In an electronic timepiece, a baseplate having a pair of opposed major surfaces, a magnetic shield plate disposed in continuous contact with one of the major surfaces and a stator disposed on the other of the major surfaces. A pin is inserted through the magnetic shield plate, baseplate and stator and includes a head portion bearing against the magnetic shield plate, and is engaged by a screw having a head bearing against the stator for fixing the shield plate, baseplate and stator between the head portion and the screw head. The shield plate includes an inwardly sloped aperture for receiving the head portion of the pin, and the head portion has a tapered peripheral surface complementary to the inwardly sloped surface of the aperture. The head portion is thinner than the shield plate and does not protrude beyond a surface of the shield plate, and because the shield plate is in continuous contact with the base plate it is not deformed by the head portion of the pin bearing thereagainst.
    • 在电子钟表中,具有一对相对的主表面的基板,与主表面中的一个连续地连接的磁屏蔽板和设置在另一个主表面上的定子。 插销穿过磁屏蔽板,底板和定子,并包括一个靠在磁屏蔽板上的磁头部分,并与一个具有头部轴承抵靠定子的螺钉啮合,用于固定屏蔽板,底板和定子在磁头之间 部分和螺丝头。 屏蔽板包括用于接收销的头部的向内倾斜的孔,并且头部具有与孔的向内倾斜的表面互补的锥形外周表面。 头部比屏蔽板薄,不会突出超过屏蔽板的表面,并且由于屏蔽板与基板连续接触,所以不会被其轴承的头部的头部变形。
