Abstract: PURPOSE:To obtain accurate positioning by offsetting an offset due to a difference between diffraction efficiency values on two zero crossing points of a difference signal obtained by converging diffraction light beams obtained through two kinds of diffraction gratings to a straight line extending in the (y) direction. CONSTITUTION:The (y) direction pitches of two 1st diffraction gratings 21 and one 2nd diffraction grating 22 are respectively different. Thereby, two 1st diffracted beams obtained from the two gratings 21 are transferred at a diffraction angle different from that of the 2nd diffraction light obtained by the 2nd grating 22 and respective beams are detected by individual sensors 32, 33. A difference between the intensity signal of the two 1st diffraction light beams and that of the 2nd diffraction light beam obtained by the detections is calculated and a difference signal having two zero crossing points is found out. The intermediate point between the two zero crossing points is set up on a positioning point, the coordinate value of the intermediate point is calculated and the 1st and 2nd objects are positioned so as to obtain the coordinate value of the intermediate point. Consequently, the accurate positioning of the two objects is executed without generating an offset.

Title: Double pole type magnetic seal
Inventor: ASANOME SATORU
IPC: F16J15/43
Filed: 1990-05-17
Abstract: PURPOSE:To make a magnetic fluid so as not to exert a bad influence on apparatuses in a closed box body as scattering around in this box body by making an interval between a first pole piece at the outer side of the closed box body and a spindle shaft larger than that between a second pole piece at the inner side of the box body and the spindle shaft. CONSTITUTION:In a recording medium rotational driving part of a magnetic disk unit, a diameter of a part corresponding to a first pole piece of a spindle shaft 4 is formed to be smaller than that of a part corresponding to a second pole piece 8. In consequence, since both magnetic fluids 12 at the side of the first pole piece 6 and at the side of the second pole piece 8 are of homogeneous, any possible scattering of these magnetic fluids 12 with pressure fluctuations in each space A being partitioned off in space among a permanent magnet 10, these first and second pole pieces 6, 8, the magnetic fluids 12 and the spindle shaft 4 comes to occurs preferentially on the magnetic fluid being interposed between the first pole piece 6 and the spindle shaft 4 in consequence. Accordingly, such a fear that the magnetic fluid is scattered in the inner part of a closed box body 2, where airtightness is required, is brought to nothing unless some exceptional sudden pressure fluctuations occurs in these internal space A of a magnetic seal.

Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To ensure effective heat change by controlling a refrigerant circulation direction in a heat pump cold/hot water machine using a plate type one as a utilization side heat exchanger and a non-azeotropic mixing refrigerant. SOLUTION: A non-azeotropic mixing refrigerant forms a temperature gradient in a condensation process differing from a case with a single refrigerant. In consideration with this, upon cooling operation a controller 8 controls a four-way valve 5 such that a heat exchange method in a utilization side heat exchanger 4 is a parallel flow upon cooling operation while it is a counter flow upon heating operation. Hereby, even when the utilization side heat exchanger 4 is a plate type one with a refrigerant being a non-azeotropic mixing refrigerant, the same performance can be obtained that of a prior are heat pump cold/hot water machine only with a control method for the four-way valve 5.

Abstract: PROBLEM TO BE SOLVED: To secure contrast, to improve decorative property, to simplify a production process and to reduce a cost in the decorative material of a game board. SOLUTION: A reflection film is provided with a reflection pattern by small planes 20a and 20b and a reflection layer obtained by vapor-depositing aluminum on it.

Reflection does not occur in terms of a dot (it is not irregular reflection) and the small planes 20a and 20b are made to be a unit. Besides, rainbow state color change occurs by light division of the diffraction grids and various hues are obtained by viewing angle or position. The reflection rate of the surface is sufficiently high, sufficient contrast is obtained and also decorative property is also improved.
