Title: Collector shoe supporting device
Inventor: INOUE KUNIO
IPC: B60L5/22
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent the one-sided abrasion of sliders and the turning over of a collector shoe by making the height of the rotational fulcrum of the collector shoe from the upper surfaces of the sliders selective, so as to offset the moment generated by the frictional forces from the advancing direction between a stringing and the sliders which occur at the rotational fulcrum of the collector shoe with the moment caused by a wind pressure. SOLUTION: While a vehicle is running, frictional forces F act on the upper surfaces of sliders 1a and 1b, because the sliders 1a and 1b slide on a stringing 13. In addition, a wind pressure W acts on a collector shoe at a distance y2 from the rotational fulcrum O of the collector shoe, which is the center of the wind pressure applied to the front face of the collector shoe in the advancing direction. Because of these applied forces, a clockwise moment occurs due to the frictional force F1 and a counterclockwise moment occurs due to the wind pressure W at the rotational fulcrum O of the collector shoe. Therefore, when the distances y1 between the upper surfaces of the sliders 1a and 1b and the rotational fulcrum O of the collector shoe are selected so as to make the two moments equal to each other, the pushing-up forces P which are applied to the sliders 1a and 1b to bring the sliders 1a and 1b into contact with the stringing 13 uniformly act on the sliders 1a and 1b within a width X of the sliders 1a and 1b.

Title: Optical fiber type light wavelength converter
Inventor: CHIKUMA KIYOBUMI
IPC: G02B3/04
Filed: 1988-05-20
Abstract: PURPOSE:To converge a 2nd higher harmonic almost to the limit of diffraction by a single lens without increasing the number of components newly by using the single lens which is formed by adding a term of 1st order to a general aspherical surface of 10th order as a condenser lens for light which has its wavelength converted by a light wavelength converting element. CONSTITUTION:Secondary light which is the 2nd higher harmonic projected from an optical fiber type light wavelength converting element 10 enters the condenser lens 30 and is converged by this condenser lens 30 almost to the limit of diffraction. The condenser lens 30 consists of the single lens having two refracting surfaces and at least one of the refracting surfaces is shaped as shown by an equation I wherein the term (height from the optical axis to the aspherical surface) Y of 1st order is added to the general aspherical surface of 10th order. In the equation I, Zi is the distance from a plane which passes the peak of the lens and is perpendicular to the optical axis to a point of the aspherical surface of height Y from the optical axis, Ci the reciprocal of the radius of curvature at the light point between an (i)th plane and the center optical axis, Ki and A1<(1)>-A10<(1)> constants, and Y the height from the optical axis to the refracting surface. Consequently, the 2nd higher harmonic can be converged almost to the limit of diffraction by the single lens without increasing the number of components newly.

Title: Gasoline direct injection engine
Inventor: NODA TORU
IPC: F02D13/02
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To reduce the deposition amount of fuel on the piston crown and cylinder bore wall of a gasoline direct injection engine while it is cold. SOLUTION: At a normal operation, an exhaust valve (EXH) and an intake valve (INT) are overlapped in opening, and a fuel injection is carried out while the intake valve opens. At a cold operation, on the other hand, the exhaust and intake valves are no longer overlapped in opening so that the exhaust valve is closed before TDC and the intake valve is opened after TDC, and a fuel injection is preformed between the exhaust valve closing and the intake valve opening. This control, which means a fuel injection into the high- temperature combustion gas that remains in the cylinder, promotes the carburetion of fuel spray, and allows a fuel injection nearer to TDC that avoids fuel deposition on the piston crown and bore wall.

Title: Mirror position controller for projection characteristic measuring apparatus of lens
Inventor: YASUKAWA YUSUKE
IPC: G01M11/02
Filed: 1985-06-10
Abstract: PURPOSE:To enable highly accurate control of a mirror with a simplified construction of a controller, by arranging a light source near a lens to be measured while a light receiver is mounted on a projector to detect the light source through the mirror. CONSTITUTION:Light projected from a collimator 4 as projector is reflected with a mirror 5 to irradiate a lens at a colatitude theta. In this case, when the light is projected at a specified lens position 1, a light receiver 10 mounted on the side of the collimator 4 detects a light source 11 set near the lens through the mirror. When the position along the moving shaft of the mirror 5 is not proper, the light from the collimator 4 is projected at the position deviated from that as specified, as indicated by the alternate long and short dash line and hence, the light receiver 10 fails to detect light of the light source 11. The position of the mirror 5 is controlled by detecting the propriety of the position thereof on the basis of the signal from the light receiver 10.

Abstract: PURPOSE:To enable high precision measurement without anisotropy in measurement force by utilizing the floatation phenomenon of a magnet within a cylindrical superconductor which forms a residual field to contactless-hold a filler partly fixed with a magnet. CONSTITUTION:A cylindrical superconductor 2 prepared from a superconductive material of strong pinning force is dipped in a liquid nitrogen 3 to cool down into a state of superconductivity. An electromagnet 4 provided in the outer periphery of the cooled conductor 2 is electrified to apply a magnetic field: increasing its intensity drives a magnet flux into the conductor 2, and stopping the electromagnet is followed by formation of a residual field. The filler 1 with a permanent magnet 5 fixed at an end is inserted into this conductor 2. The magnet 5 contactlessly floats and stays at the position of the peak of a residual field, that is, a position where the electromagnet 4 is arranged. Upon start of measurement, a measurement object contacts a ball 6 at the filler tip to apply a slight measurement force resulting in displacement of the filler 1 and the magnet 5. A separately provided sensor senses this displacement.
