IPC: G01M11/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which an image quality can be evaluated accurately by a method wherein an image noise caused by a change in the fine surface structure of an image irradiated with light is separated from an image caused by a change in the internal structure of the image, a photometric operation is performed and a colorimetric operation is performed. SOLUTION: Incident light 4 as a luminous flux which is emitted from a light source 2 equipped with a collimator and which is linearly polarized to a P-direction or an S-direction is shone at an image 1 to be evaluated, and reflected light 5 is separated into a P-direction component and an S-direction component by a polarizing filter 6. For example, when P- polarized light is used as illumination light, the light is separated into a P-direction component and an S-direction component, the P-direction component is input to a light-receiving element 8, a photometric operation and a colorimetric operation are performed by adding surface reflected light to internal reflected light 1.  On the other hand, when S-polarized light is used as illumination light, the S-direction component is input to the light-receiving element 8, and the photometric operation and the colorimetric operation of only internal reflected light 2 are performed. At this time, the internal reflected light 1 is equivalent to the internal reflected light 2, an image processor 11 computes the photometric value and the colorimetric value of only a surface component by a difference computing operation. In addition, the internal reflected light 2 is doubled, the photometric value and the colorimetric value of only the internal reflected light are computed, and two-dimensional image information is obtained together with position information by a position control circuit 9.

Title: Hydraulic reproducing unit
Inventor: TOYOOKA TSUKASA
IPC: F15B11/00
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To secure good operability by detecting a state quantity which exerts effect on a flow rate of pressure oil to be fed to plural actuator, compensating a driving signal according to this value, and adjusting a flow rate of reclaimed oil to be controlled by a variable resisting means. SOLUTION: While discharge pressure in a hydraulic pump 1 by a pressure detector 101 is low and a hydraulic fluid temperature in a temperature gauge 51 is high, a large target current is selected to the discharge pressure and the hydraulic fluid temperature in the hydraulic pump 1, generating each driving signal of respective minimum values. Therefore this large driving current conformed to a signal out of a control unit 100 is outputted to a solenoid proportional reducing valve 105, and when pressure in a line 12 of a regenerative selector valve 6 becomes more than the pressure in a line 10C, a part of return oil from a directional control valve 2 flows into the side of the line 10C.  And it is joined together with pressure oil out of the hydraulic pump 1, whereby a flow rate of pressure oil to a bottom side 4a of an arm cylinder 4 increases for a portion of reclaimed oil out of the line 12, and thus a travel speed of the cylinder 4 becomes quickened. While the hydraulic fluid temperature is low, the travel speed of the cylinder 4 becomes more lated than in time of regeneration. Accordingly operability becomes improved.

Abstract: PURPOSE:To decrease the quantity of the space propagating light condensed by using a lens is made incident on a clad layer and to stabilize optical communication by convergently molding a clad layer and allowing only the core to remain, thereby forming the front end of the fiber. CONSTITUTION:The front end of the optical fiber 3, the end face at the front end of the core 1 of which is the plane orthogonal with an optical transmission line is so constituted that the clad layer 2 is convergently molded and only the core 1 remains.
