Title: Dc -dc converter and its method of output voltage ripple elimination
Inventor: JIEFURII JIYON BOIRAN
IPC: H02M3/28
Filed: 1993-11-24
Abstract: PURPOSE: To suppress output voltage ripple by an arrangement wherein upper and lower windings have a specified relative turn ratio and the secondary winding is branched such that a constant input voltage is applied to a filter inductor and the volt second to be sustained is minimized. CONSTITUTION: A power transformer 110 comprises primary and secondary windings 111, 109 connected, respectively, with power switches FET 103, 104. The secondary winding 109 is split into upper and lower windings 112, 113 at a tap 114. Turn ratio of the transformer is associated with at n:1:m for the primary winding 111 and winding segments 112, 113. A converter circuit is operated by conducting a current alternately through FETs 103, 104. The FET 103 is conducted only during a designated time of duty cycle D and the FET 104 is conducted only during the remaining time (1-D). A control circuit 126 detects the output voltage of the converter and compares the detected output voltage with a reference to generate an error voltage before varying the relative connection time of D and 1-D.

Title: Dimension measuring method
Inventor: TATSUMI MASAKI
IPC: G01B11/02
Filed: 1992-11-26
Abstract: PURPOSE:To accurately measure the dimension of an object to be measured by preliminarily arranging other parallel patterns to the object to be measured of parallel patterns at a definite interval and measuring the pitch thereof and the dimension of the object. CONSTITUTION:For example, an object 1 to be measured is a pattern left after etching and other pattern 1a is arranged at the position of a definite pattern arranging pitch 2 in parallel to the pattern. The width dimension of the object 1 is fluctuated, for example, by the etching conditions at the time of formation but the pitch dimension 2 is not fluctuated. The measurement due to laser beam (irradiation axis mark 3) is performed by measuring two places corresponding to the width of the object 1 and the pitch dimension 2 with the other pattern 1a. When the length of the pattern arranging pitch 2 at the time of planning is set to A and the dimensions measured from a laser beam reflecting waveform 4 are set to 4a, 4b, the width dimension L of the object 1 can be calculated according to formula L=A.4a/4b. Therefore, even when the object 1 and laser beam do not cross each other at a right angle, highly accurate measurement can be executed.
