摘要： PROBLEM TO BE SOLVED: To improve the conversion efficiency of a solar energy use system without using electric power for the detection and tracking of the sun direction of a solar panel. SOLUTION: This automatic solar follow-up-system makes a solar panel of which the center is supported on a mount by a spherical sliding bearing follow according to the change of the incidence angle of sunlight. Four points located at the equal distance on the north, south, east and west from the spherical sliding bearing for supporting the solar panel are supported by rods connected to four independent air cylinders. Each air cylinder is connected to a heat collector tank by a tube set on the mount in the symmetrical direction to the center of the panel (when the direction is the west, the symmetrical direction is the east, and when the direction is the south, the symmetrical direction is the north). The collector tank is expanded by the enclosed gas warmed by the sunlight, and a piston of the air cylinder is pushed. A rod attached to the piston pushes up the contrary side to the incident direction of the sunlight of the solar panel, and thereby the solar panel is faced to the sun. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： A droplet sensor includes an optical cover having a curved surface that forms a part of a spheroid, a protective film that covers the curved surface of the optical cover, a light source provided at a first focal point of an ellipse facing the curved surface, and a photodetector provided at a second focal point of the ellipse. The refractive index of the protective film is greater than the refractive index of a liquid to be detected. A sensing region is determined by a range of an incident angle at which a light beam emitted from the light source and incident onto the curved surface is totally reflected at the interface between the protective film and a gas, and is not totally reflected at the interface between the protective film and the liquid to be detected.

摘要： An optical disc apparatus, which executes tracking control for an objective lens by generating a push-pull signal, includes a determination unit which detects symmetry of the push-pull signal and determines whether balance of signal characteristics of the push-pull signal is good, a lens shift amount detection unit which detects, in a case where the determination unit determines that the balance of the signal characteristics of the push-pull signal is not good, a lens shift amount of the objective lens in such a manner as to improve the balance of the signal characteristics, a memory unit which stores the lens shift amount that is detected by the lens shift amount detection unit, and an addition unit which constantly applies the lens shift amount, which is stored in the memory unit, to a tracking actuator which shifts the objective lens.

摘要： A droplet sensor includes an optical cover that forms part of a spheroid, a major axis of the spheroid being a vertical axis, a light emitting/receiving device disposed at a position offset from a first focal point of the spheroid along the major axis, and a reflector disposed in vicinity of a second focal point of the spheroid. The optical cover has an effective detection area between the light emitting/receiving device and the reflector. The effective detection area satisfies a total internal reflection condition at an interface with a gas, and does not satisfy the total internal reflection condition at an interface with a liquid. The reflector reflects, towards a light receiving surface of the light emitting/receiving device, light totally reflected by the effective detection area, or reflects, towards the effective detection area, light directly incident on the reflector from the light emitting/receiving device.
