IPC: B66B9/04
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To eliminate the trouble that the operation of an elevator is stopped for a long time at the time of checking and cleaning a filter of an oil returning device for hydraulic elevator and that the hydraulic fluid is over flowed from a ground part by clogging of the filter. SOLUTION: As an oil returning pump for sending the hydraulic fluid 2 leaked from a plunger 15 into a tank 1 through oil returning pipeline 31, 9, 8, a diaphragm pump 34 capable of sucking and discharging the hydraulic fluid 2 including the foreign material is used. Looseness of a drain filter 11 for eliminating the foreign material included in the hydraulic fluid 2 in a machine room is set equal to or less than the looseness of a suction filter 10 for filtering the hydraulic fluid 2 sent from inside of a tank 1 to a hydraulic jack 7. The drain filter 11 is provided with an escape part (a through hole) capable of flowing the hydraulic fluid 2 without filtering it when clogging is generated in a filtering means (a mesh part) thereof.

Title: Method and device for dividing region of picture
Inventor: MITSUMOTO SAYOKO
IPC: H04N19/91
Filed: 1996-03-07
Abstract: PURPOSE: To reduce the error in region division by dividing a region corresponding to a mapping as a specific feature region on a picture in accordance with a prescribed attribute to control the selection method for similar parameters. CONSTITUTION: Conversion is repeated N times from an initial point a0, which is defined as a specific point on a coordinate system by a prescribed attribute, in accordance with this attribute to obtain plural mapping points an (n=1,... N). Region corresponding to plural sections including points am (m=0,... N-1) to be transformed at plural mapping points an (n=1,... N) are obtained as mapping. In this case, regions (a) to (d) to determine the attribute contents are determined. For example, these regions are determined by using several initial points as representative points. Attributes of initial points other than representative points are determined by regions (a) to (d) which N mapping points are included. Consequently, attributes of N-times mapping are determined for each feature region of the picture, and therefore, attributes of N mapping points are determined to divide a feature region.

Abstract: PROBLEM TO BE SOLVED: To attain the remote control of a flying means even at the outside of a foreseeing range of radio waves by relaying the control data and the flying data which are transferred between the flying means and a control means via a relaying satellite. SOLUTION: A transceiver 8 transmits the image data Dv and the unmanned aircraft status Ds via an antenna 7.
