Title: Defect detection method for glass fiber sheet
Inventor: HONMA CHUICHI
IPC: G01N21/89
Filed: 1994-07-11
Abstract: PURPOSE: To detect the defect even of a sheet having rough texture, e.g. a glass fiber sheet, surely by disposing an illumination light source while shifting laterally by a predetermined distance from the image pickup optical axis of a CCD camera. CONSTITUTION: A glass fiber sheet 1 being transferred from the left to the right in the production process is irradiated uniformly in the breadthwise direction from a light source, i.e., a high frequency fluorescent light 2, disposed on the underside of a glass fiber sheet 1. The sheet 1 is composed of unraveled fibers and the illumination light is scattered in the sheet 1. A CCD camera 3 disposed above the sheet 1 while facing the fluorescent light 2 picks up the image of illuminated part which is then converted into an electric signal in order to detect the defect. In the direct light transmission method where the image is picked up by means of a camera 3' having image pickup optical axis aligned with the light 2, the detection signal has S/N ration of 1.17.  In the indirect light transmission method where the image is picked up by means of a camera 3' having image pickup optical axis shifted by 2.5mm to the right from the light 2, the S/N ratio is 3.0. When the indirect light transmission method is used, the S/N ratio can be increased even for a sheet having rough texture and a defect of the sheet 1, e.g. black point or hole, can be detected surely regardless of noise.

Title: Closing device of hydraulic circuit for internal massing-driving
Inventor: KANEKO ZENJI
IPC: F15B11/08
Filed: 1983-09-30
Abstract: PURPOSE:To tightly lock an actuator even if a large intertial load acts, by interrupting continuity from the actuator to a selector valve when a pressure on the delivery side of a hydraulic pump becomes below a specified value. CONSTITUTION:Installing closing valves 30, 31 between a selector valve and an actuator 1, continuity from a selector valve 4 to an actuator 1 is interrupted when a pressure on the delivery side of a hydraulic pump 2 becomes below a specified value. Therefore, the closing valves 30, 31 are always closed while the engine stops, and each pipe-line is not connected to a tank 23 or the hydraulic pump 2 even if the selector valve 4 is changed over by mistake. Thus, even if the selector valve 4 is changed over when a large inertial mass acts on the actuator 1 as an external force, oil-lock in pipe-line is maintained, and a danger whereby the actuator 1 operates, can be positively prevented.

Filed: 1991-07-23
Abstract: PURPOSE: To lock a slip assembly at an arbitrary position where the assembly can be easily set to a casing having various diameters by maintaining the position of an upper slip member along a mandrel when the slip member is moved. CONSTITUTION: An anchor 10 used for setting a casing in an oil well after the casing is inserted into the well contains a mandrel 20 having a fluid passageway 18 to supply a working fluid to a piston assembly 42.

IPC: H04N5/21
Filed: 1982-10-20
Abstract: PURPOSE:To eliminate effectively a ghost, by using two comparators having an equal threshold value and therefore discriminating a ghost from a DC offset within one field. CONSTITUTION:The input to a comparator 22 is generated in the positive direction of a differential output as shown by (a), and at the same time the DC level of the input is lower than the threshold value Th of the comparator 22 shown by broken lines. In such a case, the differential output of a comparator 23 is set in the negative direction owing to an inverse amplifier I1. The comparator 23 has the same threshold value and bias as those of the comparator 22, and therefore the DC level of the comparator 23 is lower than the value The as shown by (b). As a result, the outputs of both comparators are shown by (c) and (d). The output of a subtractor 29 is set at +2 only at the area where a differential output is generated and at (0) in other areas as shown by (e). In the same way, only the area where a differential output is generated is set at + or -2 with other areas set at (0) respectively also with cases 2-4.
