    • A timepiece movement comprises a first luminous element for emitting light, a second luminous element for emitting light, and a light-receiving element for receiving the light emitted by the first and second luminous elements. A second wheel has an aperture through which light from the first luminous element may pass and a reflecting portion. A first transmitting wheel transmits a rotational drive to the second wheel as a function of second time and has an aperture through which light from the first luminous element may pass and which is positioned to become aligned with the aperture of the second wheel. A rotational minute wheel has apertures disposed at equal angular intervals and through which light from the second luminous element may pass. A rotational hour wheel has apertures through which light from the second luminous element may pass. Each of the apertures of the hour wheel are positioned to become aligned with respective ones of the apertures of the minute wheel during rotation of the minute and hour wheels. A second transmitting wheel transmits a rotational drive to the minute wheel and the hour wheel as a function of minute time and hour time, respectively. The second transmitting wheel has a plurality of apertures disposed at equal angular intervals and through which light from the second luminous element may pass. The apertures of the minute wheel are positioned to become aligned with respective ones of the apertures of the second transmitting wheel during rotation thereof.

    • A clock movement includes a circuit board, first and second motors, a minute wheel connected to the first motor by a first gear train and an hour wheel connected to the second motor by a second gear train. The first and second gear trains preferably extend in a first direction, and the first and second motors are respectively disposed on opposite sides of the first and second gear trains and extend in a second direction transverse to the first direction. A first detection device detects when the minute hand is in a predetermined reference position and a second detection device detects when the hour wheel is in a predetermined reference position. The first detection device includes a minute detection sensor mounted on the circuit board and having a first light-emitting device and a first light-receiving device. The second detection device includes an hour detection sensor mounted on the circuit board and having a second light-emitting device and a second light-receiving device. The clock movement has a simple construction and is easy to manufacture, is suited to mass-production and can be manufactured at low cost.

    • The present invention discloses a power-steering pump which may reduce in a very stable manner the flow rate of the hydraulic liquid under pressure to be delivered to a power steering system with increase of the rotational speed of an engine beyond an idling speed and which may easily change the above rate reduction or attenuation characteristic depending upon the types of the automotive vehicles and power steering systems thereof. A flow-control valve which is disposed in parallel with the axis of a pump mechanism is provided with a variable-area orifice which determines the flow rate attenuation characteristic and which is defined by an orifice groove cut through a flange of a partition wall member and an enlarged-diameter portion at the free end of a control rod extended through the partition wall member from the front end of a control spool of the flow-control valve. The flow-control valve is so arranged as to be freely detached from the pump independently of the pump mechanism so that a partition wall member having a suitable orifice groove may be placed, thereby changing the flow-rate attenuation characteristic as needs demand.
    • 本发明公开了一种动力转向泵,其可以以非常稳定的方式减少压力下的液压液体的流量,以便随着发动机的转速超过怠速转速而传递到动力转向系统,并且可以 根据机动车辆的类型和动力转向系统容易地改变上述速率降低或衰减特性。 与泵机构的轴线平行设置的流量控制阀设置有可变面积孔口,该可变面积孔口确定流量衰减特性,其由通过隔壁构件的凸缘切割的孔槽限定, 控制棒的自由端的扩径部分从流量控制阀的控制阀芯的前端延伸穿过分隔壁件。 流量控制阀被设置为独立于泵机构从泵自由分离,从而可以放置具有合适的孔槽的隔壁构件,从而根据需要改变流量衰减特性。
