Filed: 2001-11-01
Abstract: PROBLEM TO BE SOLVED: To provide an injection molding device capable of improving the dimensional precision of a finished product molded product, even when the viscosity of a molding material differs and a method for controlling the device. SOLUTION: In the motor-driven injection molding device, when a molding material 7 loaded from a molding material loading chute 10, is forced into a mold 9, a molding pressure is detected by a pressure sensor 3 at the point of time when the arrival of a screw 6 inside a cylinder 30 at a specified dwell pressure switching position by means of an electric motor 40, is detected using a position sensor 1 and thus the operation is changed over from an injection step to a dwell pressure application step. In the dwell pressure application step, a target dwell valve is calculated by multiplying the molding pressure by a constant of proportionality which is previously determined, for example, per kind of the molding material 7 and the pressure control is carried out using the pressure sensor 3 and a control device 100 so that the dwell value reaches the target dwell value.

Abstract: <P>PROBLEM TO BE SOLVED: To prevent A distortion or a deflection due to dead weight of a large- sized mask and to accurately perform the parallelization of a work with reference to the mask in a contact aligner or a proximity aligner.  <P>SOLUTION: The mask M is fixed and held on the lower surface of a mask stage 1 by vacuum suction.

At such a time, the vacuum suction of the mask M is restarted after temporarily releasing the vacuum suction of the mask M by the mask stage 1 and finishing operation for parallelization. By releasing the suction of the mask M when force is exerted from the work W on the mask M from below, the distortion or the deflection of the mask is corrected by the force exerted from the work W on the mask M. Therefore, space between the mask M and the work W is made constant, and the variance of exposing accuracy can be reduced.  <P>COPYRIGHT: (C)2003,JPO

Filed: 2001-12-10
Abstract: PROBLEM TO BE SOLVED: To optimize the imaging interval for making a sufficient interval for filling air bubbles as an contrast medium. SOLUTION: A first signal strength ik- of an ultrasonic echo from a point of measurement inside a subject is measured by an ultrasonic beam for breaking air bubbles existing as a contrast medium. Then after a period Tk, a second signal strength ik+ of the ultrasonic echo from the point of measurement inside the subject is measured by the ultrasonic beam for breaking air bubbles. Next, when a comparative coefficient (w) is 0<w<1, it is determined whether ik+ satisfies ik+>=w.ik-. The shortest period Tkmin to satisfy the inequality is found by repeatingly measuring and determining by varying the period Tk, and a period longer than the shortest period Tkmin is set as the scanning interval to execute the harmonic imaging. As a result, the imaging can be executed with a concerned region filled with sufficient air bubbles.
