Title: Method and equipment for measuring mtf
Inventor: INOUE SHINICHI
IPC: G01M11/02
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To simplify focusing by measuring the distribution of the quantity of reflected light a plurality of times while varying the distance to a basic material during projection of a sine wave image and determining each modulation and then measuring the MTF using the maximum value thereof. SOLUTION: A sine wave image of some spatial frequency is projected from a projector 1 onto a basic material 2 and the measuring distance from an object to a basic material 2 is varied. A reflected light quantity measurement controller moves a measuring table 6 through a driver 61 to vary the measuring distance to a basic material 2 and a reflected light quantity measuring equipment 3 measures the reflected light quantity distribution of the sine wave image projected to the basic material 2. A modulation operating/recording unit operates and records a modulation from the reflected light quantity distribution of the sine wave image. After measurements are taken by varying the distance by a target number of times, a maximum modulation is determined and employed as a modulation for measurement at that spatial frequency in the calculation of MTF.

Title: Method and apparatus for inspecting pattern
Inventor: HIZUKA TETSUO
IPC: H05K3/46
Filed: 1992-03-04
Abstract: PURPOSE:To obtain the accurate information of a height by providing a pumping-light-component extracting means and a second light-point-position detecting means. CONSTITUTION:When laser light rays L1 and L2 are projected on an object 27 to be inspected, the ray L1 is totally reflected as the reflected laser light ray r1 from an upper wiring layer pattern 27C. The height of the pattern 27C is detected with the ray r1. When the laser light ray is projected on a transparent film 27B, the excited fluorescence is generated in the film 27B when the film is the organic material. The generated amount of the fluorescence (b) in the vicinity of the surface of the film 27B becomes the maximum value. Therefore, the height of the surface of the film 27B can be detected by detecting the position. The thickness of the pattern 27C can be detected by comparing the height of the surface of the film 27B and the height of the pattern 27C. Namely, when the height of the film 27B is subtracted from the height of the pattern 27C, the thickness of the pattern 27C is obtained.

Title: Device and method for displaying video
Inventor: FUJIMURA RYUICHI
IPC: H04N7/01
Filed: 1995-03-08
Abstract: PURPOSE: To allow a display device to display a video signal with different total number of scanning line such as NTSC/HDTV without causing the devia tion of display. CONSTITUTION: After a prescribed coefficient is multiplied with a video signal for a horizontal scanning period in a relation of relative position of scanning lines between the NTSC and the HDTV, the results are summed and the signal speed is converted. For example, one horizontal scanning signal N11 of the NTSC is stored in a memory and delayed, a factor 7/8 is multiplied with the signal and a factor 1/8 is multiplied with a succeeding horizontal scanning signal N12 and they are added. The added video signal is stored in a memory and read synchronously with the HDTV horizontal scanning signal H11. According to the above procedure the NTSC signal is displayed on the HDTV display device by taking the spatial position into account without impartial scanning line information with less image quality deterioration.

Title: Ignition timing controller for engine
Inventor: SUGANO YOSHIAKI
IPC: F02P5/15
Filed: 1988-02-29
Abstract: PURPOSE:To make proper ignition timing settable to any vibration in load by performing no compensation for the ignition timing as long as the specified time since a load change has been detected. CONSTITUTION:A controller 30 compensates ignition timing from a deviation between mean speed and momentary speed of an engine 1 at idling state when an idle switch 12A is turned to ON. Here a microcomputer 32 erects a flag in response to a signal read from an air-conditioning switch 19 via a driver 40, and judges of whether load of the engine 1 is changed or not by comparison between both states of the last and this time flags. If the load changed, lag time is set to a timer 38, and the ignition timing is made so as not to be compensated even if it is at the time of the idling state. With this constitution, since a speed upping rate is not checked by timing delay compensation, the engine is reachable to the required speed so quickly.
