    Abstract: PURPOSE:To obtain a color filter which has small reflection factor and a shading part of high accuracy, by providing the shading part for shading between the color element corresponding to a color light pattern which has been formed by discharging a specific light discharging sensitive composite, and each color element. CONSTITUTION:A light pattern of color is performed by eliminating the part between the color elements of the color filter formed against the chromatic state of the light discharging sensitive material which has been formed by respectively superposing in layers or equally mixing the light discharging sensitive composite where the visible light absorption spectrum in a chromatic state is in 400-500nm, the light discharging sensitive composite where it is 500-600nm, and the light discharging sensitive composite where it is in 600-700nm. The shading part is provided in order to optically shade the part between the color element against the color light pattern formed by selectively discharging the light discharging sensitive composite in each chromatic state, corresponding to each absorption spectrum, by the stimulus of said each component color light.

    Abstract: PURPOSE:To keep a fixed level of liquid temperature, etc. with a simple constitution by making use of the shape memory effect of a shape memory alloy. CONSTITUTION:Both the cool water and warm water are supplied to a control tank 1 from a cool water source 2 and a warm water source 3 respectively. The flow rate of water is controlled by valves 4 and 5. The coupling members 10L and 10R and shape memory alloys 9 and 10 are connected to ends 6L and 6R of a turning member 6 which turns centering around a shaft 7. Thus the valves 4 and 5 are opened and closed. These coupling members 10L, 10R and memory alloys 9, 10 are under the liquid level of the tank 1. Then the restoring force is produced at the alloy 9 shown by a broken line in the figure when the liquid temperature in the tank 1 exceeds an allowable range. Thus the alloy 9 begins to be reset to its memory shape and turns as shown by arrows. As a result, the valves 3 and 4 are closed and opened respectively. Then the cool water is supplied from the source 2 to lower the liquid temperature.

    Abstract: PURPOSE:To adjust the quantity of light by varying the distribution of magnetic fluid as a light shielding means. CONSTITUTION:When an aperture is reduced in area, a lens barrel 6 is moved to left along an optical axis to increase the gap between flat glass plates 3 and 4. The space surrounded with the two glass plates and magnetic fluid expands and the pressure in it drops, but the space communicates with the outside through a hole 8, so the magnetic fluid is pressed by the atmospheric pressure to flow and the pressure in the space 7A is equalized to the atmospheric pressure all the time to obtain a shape as shown by a space 7B. When this variation is viewed in the front elevation in the optical axis direction, the area of the aperture decreases from 9A to 9B as shown in a figure. When the aperture is increased in area to the contrary, the lens barrel 6 is moved to the left in a figure 3 along the optical axis to narrow down the gap between the flat glass plates 3 and 4.
