Abstract: To provide a new mean for enhancing detection precision of an LPD by a laser surface inspecting device.
A coordinate position specific precision calibrating method for a laser surface inspecting device, which detects a Light Point Defect (LPD) on a wafer surface by injecting a laser beam to scan on the wafer surface while rotating a semiconductor wafer. The method includes: detecting a Crystal Originated Particle(COP) on a reference wafer surface respectively by a laser surface inspecting device which is a calibration object and a calibration device obtaining an X-coordinate position and a Y-coordinate position of the COP by using an orthogonal two-dimensional coordinate system; deciding the COP detected by the laser surface inspecting device which is the calibration object and the calibration device as the same COP, by using the condition, wherein a position difference on the reference wafer surface between a detecting position obtained by the laser surface inspecting device which is the calibration object and a detecting position obtained by the calibration device is within a threshold range, as a decision criterion for deciding that the COP detected by each device is the same COP; and calibrating the coordinate position specific precision of the laser surface inspecting device which is the calibration object, by adopting the X-coordinate position and the Y-coordinate position obtained by the calibration device as a truth value for the X-coordinate position and the Y-coordinate position of the COP decided to be the same COP.

Abstract: Disclosed herein is a self-zeroing dosage syringe comprising: (a) a syringe barrel which forms a volume sufficient to contain a required dosage of a fluid, a discharge end at one end of the barrel length, a plunger receiving end at the opposite end of the barrel length, (b) said plunger is movably disposed within the barrel and has a length greater than the length of the barrel, and further has at a set of multiple closely spaced indentations disposed along the length thereof, and (c) a movable dosage selection ring which is disposed around the plunger and rotatable about the longitudinal axis of the plunger; characterized in that the dosage selection ring has (1) a sleeve disposed inside the barrel, (2) a calibration on the sleeve thereof for setting the desired dosage by turning the ring until the calibration for a desired dose is reached, (3) a means for engaging the ring with the plunger allowing it to be moved cooperatively with the plunger until the ring dead ends against the syringe barrel thereby releasing the desired dosage.

Title: A reinforced permeable structure.
Inventor: HART PETER
IPC: E01C3/06
Filed: 2003-06-13
Abstract: A paving structure ( 11 ) of the type having an upper wear layer ( 12 ) and an underlying sub-base layer ( 15 ) of rigid insoluble hard particulate material forming voids for the collection of water permeating through the permeable surface where layer ( 12 ) has an intermediate reinforcing grid ( 16 ) located at an intermediate level of the sub-base layer ( 15 ) such that it is covered by an upper part of the sub-base layer ( 15 U) which is of a thickness not less than 1½ times the dimension of the largest particles in that part of the sub-base layer. A reinforcing grid ( 26 ) at the base of the sub-base layer between this and the sub grade ( 18 ) may also be provided.

Title: Open metal gasket with offset projecting portions
Inventor: CHRISTIAN ROUAUD
IPC: F16J/
Filed: 2003-10-21
Abstract: The open circular section gasket is not deformed under flattening while nevertheless ensuring the leaktightness of the two spaces to seal.</PTEXT>Each contact surface (<HIL><PDAT>16</BOLD><PDAT>) is slightly inclined and has a slightly offset projecting part (<HIL><PDAT>15</BOLD><PDAT>) such that the summits of the two projecting parts define an axis that is offset with respect to the center line (A<HIL><PDAT>2</BOLD><PDAT>) of the general circular shape of the gasket (<HIL><PDAT>10</BOLD><PDAT>). When the gasket is flattened, the contact surfaces (<HIL><PDAT>16</BOLD><PDAT>) tend to become parallel, the projecting parts (<HIL><PDAT>15</BOLD><PDAT>) come closer to the center line (A<HIL><PDAT>2</BOLD><PDAT>).</PTEXT>Application to cases of static sealing.</PTEXT>
