Title: Separation type optical head, hermetic type optical disk device and optical disk medium
Inventor: NAKAMURA SHIGERU
IPC: G11B7/09
Filed: 1990-01-19
Abstract: PURPOSE:To reduce the weight and size of a moving part by separating an optical system to the moving part and a stationary part and subjecting the condenser lens in the moving part to air floating, thereby executing the automatic rough follow up of an automatic focus. CONSTITUTION:The optical system is separated to the moving part 20 and the stationary part 10 and the condenser lens 29 in the moving part 20 is fixed to a slider 22 for air floating and is movable in the vertical direction of the disk. The lens 29 of the moving part 20 is floated slightly on the outermost periphery of the disk. The line speed varies with a difference in radial position and the air floating quantity varies. Since this change is small, the focus can be confined within the depth of focus of the lens 29 by executing the slight automatic focus control. This control is executed when the automatic focus control is executed by the air floating of the lens 29 and the rough follow-up of the automatic focus is executed. Such control is possible if there is a thin protective layer. The size and weight of the moving part 20 are thus reduced.

IPC: G01B7/00
Filed: 1988-01-20
Abstract: PURPOSE:To easily detect the eccentricity of a rotary shaft or bearing by embedding annular electrodes made of thin plates surrounding the rotary shaft in fins of a noncontact type labyrinth shaft seal part made of an electric insulator which is easier to wear than the rotary shaft. CONSTITUTION:The noncontact labyrinth shaft seal part 3 is formed of the electric insulator which is easier to wear than the rotary shaft 2 and fitted in the annular recessed part of a holding part 8. The shaft seal part 3 has plural fins 4, and the annular electrodes 5 and 6 of different internal diameter size are embedded in the fins 4 and connected to an indicator and a power source which are not shown in a figure through lead wires 7 and 7. The rotary shaft 2 is supported rotatably by the bearing 9 fixed to a partition wall 1 on, for example, a compressor side C and a motor side M. If the rotary shaft 2 or bearing 9 wears and becomes eccentric, the rotary shaft 2 contacts the annular electrodes 5 and 6 in order to deflect the indicator. The direction of the eccentricity is also detected by dividing the annular electrodes 5 and 6 into plural sectorial parts. Consequently, the eccentricity due to the wear is easily detected.

Abstract: PURPOSE:To place an intermediate shaft almost vertical, in the case of lifting a cargo, so as to improve a swivel quality of the second arm by a simple means by tilting the intermediate vertical shaft so as to fall a little to the base end side of the first arm from the lower toward the upper. CONSTITUTION:An intermediate vertical shaft 6, by which a base end part of the second arm 5 is pivotally mounted to a point end part of the first arm 3, is tilted at an angle alpha so as to fall a little to a base end side of the first arm 3 from the lower toward the upper. In this way, in the case of lifting a cargo by a hoist 7 mounted to a point end part of the second arm 5, the intermediate vertical shaft 6 is placed almost vertical by deflecting the first arm 3 in a downward direction by weight of the cargo. Consequently, in the case of lifting the cargo by the hoist 7, the second arm 5 can be almost horizontally swiveled by automatically placing the intermediate vertical shaft 6 almost vertical, and a swivel quality of the second arm 5 can be improved by a simple means.

Abstract: PURPOSE:To prevent turbine trip in such a way that opening degree of a turbine load control valve is controlled through cooling water reduction signals at the time of reducing cooling water supply to a condenser so that its steam rate can be balanced with condensing treatment capability of the condenser. CONSTITUTION:when sea water pumps 17a, 17b are tripped or when pump outlet ports 19a, 19b are closed, cooling water reduction signals S1-S4 generated in respective signal generators 23a, 23b, 24a, 24b are input into a turbine load controller 22. For example, in the event that one pump 17a out of the arranged two the sea water pumps is tripped, opening degree of a turbine load control valve 3 is controlled so that the trip signal S1 is applied as input, and the rate of steam flowing into the high pressure turbine 2 may be equivalent to the turbine load to be balanced with the steam treatment capability of the pump 17b which is not tripped. Thus, turbine trip due to a turbine load increase can be prevented, and working rate in the power plant can be improved.

That is, by using a luminous flux for passing through an area of a different pupil of the objective lens by a secondary optical system 100 further from an image of an object to be photographed which has been formed in the vicinity of a scheduled image forming surface 2 of the objective lens 1, the image of the object to be photographed is brought to image formation again on the surface of the corresponding photodetectors 5, 6, respectively. Subsequently, by deriving a relative position relation of a light quantity distribution of two object images which have been formed on the surface of two photodetectors 5, 6, by an arithmetic means 102, a focused state of the objective lens 1 is detected. In such a way, the focus detection accuracy can be improved.
