IPC: G01M11/02
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a device which can objectively evaluate performance of a lens by converting it into a numeric value. SOLUTION: A point light source made by transmissively illuminating a pinhole formed on a test chart 2 by an illuminating part 1, is formed as an image in a position of a primary image 7 by a lens 4 to be inspected. The lens 4 to be inspected is supported with a rotary part 5, and can rotate around the optical axis. The primary image 7 is picked up by an image pickup element 10 through an objective lens 8, and is taken in a personal computer 16 through an image processing device 14, and a characteristic of a shape of the image is converted into a numeric value. A performance evaluating value of the lens 4 to be inspected is calculated on the basis of this. Influence exerted on the performance evaluating value by an image pickup optical system is removed by obtaining and processing plural point light source images while rotating the lens 4 to be inspected.

Filed: 1989-12-08
Abstract: PURPOSE:To suppress the changes of the dimensions of boards by a method wherein only the parts of the metal foils of outermost layers where flexibility is required are removed by etching and dummy patterns are left as widely as possible. CONSTITUTION:Polyimide films 3 on which required circuit patterns are formed by etching and their coverlay films 4 are laid with modified epoxy adhesive layers 2 therebetween and the layers are bonded to each other by a lamination press.

Abstract: PURPOSE:To prevent an overshoot phenomenon and perform feedback control in the whole control region by setting the limit value of a duty ratio at the time of sudden acceleration so as to enable continuous operation of a waste gate valve for a specified time while maintaining a small opening thereof. CONSTITUTION:In a region where the opening of a throttle valve 8 is smaller than the specified opening degree, feedback control is performed while providing a duty ratio with the limit value so that the opening of a waste gate valve 13 does not become less than the specified value.
