Prolongation of the lifetime for reduced water is attempted. Production water that presents alkalinity is produced by utilizing raw water with ionized metallic minerals being dissolved therein and hydrogen gas H2. When inpouring the hydrogen gas together with the raw water into an electromagnetic portion in the apparatus, the hydrogen gas is bubbled and ionized to produce ions. The gas bubbles of the ionized hydrogen-ions are miniaturized. By making a metallic mineral as a core, hydrides (H&#x2212;), which are negative ions in the hydrogen ions, coordinate on the periphery of that core. The metallic minerals which are complex-ionized (complex-ionized metallic minerals) based on a fact that the hydrides coordinate are dissolved in the water stably for long period of time, so that production water which presents alkalinity, that is, reduced water can be obtained. The reduced water can be utilized as drinking water. A metal container is preferable for a refilling container.

A liquid crystal shutter, mounted on the side of a lens in a video camera, includes a pair of polarizing filters with a liquid crystal cell between them. A pulse generator generates a pulse for a predetermined length of time that is synchronized with a vertical synchronizing signal of a television signal. A controller controls an electrical field of the liquid crystal shutter to allow light from an object to be transmitted through the liquid crystal shutter in response to the pulse. Such liquid crystal shutter, having no mechanical moving parts, is much more durable than a mechanical shutter and can be easily maintained. In addition, the shutter apparatus, because it is controlled electrically, can work at high speed and can be easily synchronized with other systems.

A coaxial type electrical resistor has a cylindrical conductor, a cylindrical insulator inserted into the opening of the conductor and a cylindrical resistor inserted into the opening of the insulator. Since the insulator is between the conductor and the resistor, a distance between the conductor and resistor may be small and magnetic flux leakage reduced. Thus the resistor has a small inductance and is appropriate as a high frequency large current resistor.
