Title: Method and device for evaluating shape
Inventor: ONO YUJI
IPC: G01M11/00
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To avoid double operations of inspection for an optical part and inspection for an image recording device and to detect partial deformation with high accuracy by a method wherein a deviation between a designed cross-section of a face to be measured and a measured cross-section is calculated and an approximation equation is obtained from the deviation. SOLUTION: A cross-section measuring device 4 executes the measurement such that a stylus 3 is moved by being brought into contact with a face to be measured of an fθ lens 1 having an optical face formed by an aspheric surface. The cross-section data is operated to be calculated by an arithmetic operation circuit 5 to be indicated on a display 6. In the case where the lens 1 has a shape difference 2a having a concave lens function or a shape difference 2b having a convex lens function, each of collecting positions of rays A, B penetrating through the parts of differences 2a, 2b is shifted to a respective position in front of or rear the regular position, by virtue of respective curvature at the penetrating position. Therefore, a deviation between a designed cross- section of a face to be measured and measured cross-section is calculated and an approximation equation representing the shape difference of the face to be measured is obtained from the deviation, thereby estimating the shape in accordance with a second derivative of the approximation equation.

Title: Connecting terminal for packaged substrate
Inventor: TAKU MASAKAZU
IPC: H05K3/34
Filed: 1991-09-20
Abstract: PURPOSE:To increase the reliability of soldered strength, and improve soldering workability by keeping a terminal end at an acute angle with a printed wiring board in a direction away there from. CONSTITUTION:The bent end 2b of the soldered section of a terminal 2 is made to form an angle theta of 90 degrees or less with the copper foil 1a of a printed wiring board 1. When an aspect of workability and mass-production is taken into consideration, the angle theta approximately between 10 and 45 degrees is practical, and if the angle exceeds 45 degrees, soldered strength becomes insufficient. By maintaining the angle range between 10 and 45 degrees, a solder fillet can be formed and the soldered strength of the terminal 2 becomes sufficient. Thus, the terminal 2 is soldered to the copper foil 1a only with a wedge portion formed with the bent end 2b and the exposed copper foil 1a, and the parallel section of the terminal 2 along length G does not need soldering specifically. Furthermore, the fillet 3a does not come above the height H of the terminal 2, and incomplete soldering can be prevented.

Title: Device for approximating bezier curve
Inventor: MIYAKE KEIJI
IPC: G06T3/00
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To allow the Bezier curve approximation device that approximates a Bezier curve with several straight lines to make straight line approximation of a Bezier curve at a high speed. SOLUTION: In the case of approximating one Bezier curve by several straight lines, at first, coordinate data at four control points of the Bezier curve being an object of straight line approximation processing are entered in the step S1. Then a prescribed division number of the Bezier curve set in advance is set to a division number measurement counter in the step S2. Then a 'Bezier curve division processing' subroutine is called in the step S3, in which the division processing and the straight line approximation processing of the Bezier curve are conducted. Plural straight line coordinate data approximating the Bezier curve obtained in the step S3 are outputted in the step S4.  Thus, the Bezier curve is divided recursively until the prescribed division number is reached and end points of the Bezier curve obtained by the division are tied by straight lines to make straight line approximation at a high speed.
