Abstract:
1. Equipment for the measurement of the electromagnetic radiation coming from the half-space (corresponding to a solid angle of 2 pi) with the aid of a highly sensitive detector of low inertia arranged under a radiation-permeable dome (K), characterised thereby, that above the radiation-permeable dome (K), under which at least the one highly sensitive detector (D) of low inertia is housed, there are provided two identically or differently constructed modulators (M1, M2), which are of dome segment shape, are arranged one inside the other and which rotate at different speed in like or opposite direction about the common vertical axis (A) of both the modulators (M1, M2).
Abstract:
An optical sensor is provided to set or adjust a sensitivity thereof freely with a high accuracy. In an optical sensor, a light receiving element(20) is arranged in a housing(10). An outer filter(50) is rotatably mounted on an attachment side of the housing. A lightproof member(40) rotates in accordance with a rotation of the outer filter for adjusting an intensity of light, incident on a light receiving side of the light receiving element. The lightproof member includes a rotary shaft fixed at a central part thereof and an illumination device adjusting quantities of the light, incident on the light receiving side of the light receiving element within a range of a rotation direction of the rotary shaft.
Abstract:
A photo-detecting device having a magnetic shielding tube and a safety window is provided to prevent pollution of a photo-detector from secretion fluid of a life body by using the safety window. A photo-detecting device having a magnetic shielding tube and a safety window includes a photo-multiplier tube(11) as a photo-detector. A variable shutter(12) and a movable lens(13) are sequentially positioned on the entire surface of an incident window(19) of the photo-multiplier tube(11). The entire surface of the movable lens(13) has the safety window. A hood(18) is attached to a part contact with a target. The movable lens(13) and the variable shutter(12) make only bio-photons incident on the photo-multiplier tube(11) through appropriate manipulation. The safety window performs a filter function in such a manner that only a wavelength band of a bio-photon is incident on the photo-multiplier tube(11).

PURPOSE: A device for opening and closing a camera lens for a mobile communication terminal is provided to mechanically open/close a blade by electric energy, thereby protecting a camera lens. CONSTITUTION: An opening(9) is formed on the center of a housing(10) to make light incident on the center. A guide(18) is expanded in parallel with both sides of the opening. A slider(20) is installed on the housing to perform translation along with the guide. Blades(30,40) are connected with the translation of the slider. The blades open and close the opening. A driving unit performs the translation of the slider.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical sensor enabling sensitivity control with a simple structure, at higher flexibility and higher precision. SOLUTION: A gobo 40 formed with an opaque disk plate is rotatably pivoted. A light transmitting slit 42 for penetrating the gobo 40 is provided in the gobo 40 so that the width of the gobo 40 continuously varies over a region that is larger than 180 degrees around a rotation axis 41 of the gobo in a rotation direction. The rotation axis 41 of the gobo 40 is provided deflecting to the rotation center of a sheathing filter 50 and the gyration radius of the sheathing filter 50 is set at a larger radius than that of the gobo 40. Also, an external gear 43 is formed on the external surface of the gobo 40 and an internal gear 53 is formed on the internal surface of the sheathing filter 50, respectively. The amount of light incident on a light-receiving element 20 is controlled by following the gobo 40 the rotation of the sheathing filter 50 to rotate, based on gearing the external gear 43 with the internal gear 53.

Abstract:
PURPOSE:To attain the long life of the photomultiplier by coating a light receiving surface by a liquid crystal panel. CONSTITUTION:The light receiving surface of the photomultiplier 1 is coated by the liquid crystal panel 3. When a voltage is applied to the panel 3, the crystal structure of the part corresponding to the light receiving surface 2 is changed and the transparent surface is closed. When the device is used, a voltage applying switch 5 is turned OFF, the panel 3 becomes transparent, and the external light is inputted to the light receiving surface 2. When the device is not used, the swithc 5 is turned ON, and the panel 3 is closed.
