Abstract: [Problem] To provide a combination weighing apparatus that reduces power consumption during opening and closing operations of a hopper gate. [Solution] In a combination weighing apparatus 1, a control unit 70 controls a stepping motor 60 via a control signal that is input to the stepping motor 60. The control signal that is input to the stepping motor 60 is a voltage value corresponding to a desired current value. The control unit changes the control signal to the stepping motor 60 in conjunction with a change in the settings of the opening and closing speed of the gate 20. As a result, it becomes possible to supply power needed for the operation of the gate 20, and power can be saved.

Abstract: In a light emitting device, a P-type first region (506) and a P-type third region (508) are placed on both sides of an N-type second region (507) of a rod-like light emitting element (505). Therefore, even if connection of the first, third regions (506, 508) of the rod-like light emitting element (505) relative to the first, third electrodes (1, 3) is reversed, a diode polarity relative to the first, third electrodes (501, 503) is not reversed, making it possible to effectuate normal light emission. Thus, a connection of the first, third regions (506, 508) relative to the first, third electrodes (501, 503) may be reversed during a manufacturing process, making it unnecessary to provide marks or configurations for discrimination of orientation of the rod-like light emitting element (505), so that the manufacturing process can be simplified and manufacturing cost can be cut down.
