Title: Method for measuring image quality
Inventor: JANKO BOZIDAR
IPC: H04N7/30
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To obtain a quantity of distortion in a video signal due to video compression processing by obtaining a value of edges in an image so as to allow a kernel having a space corresponding to a prescribed block size to generate a plurality of correlation values in correlation with the value of the edges and generating an evaluation value from the correlation value. SOLUTION: A luminance component or over in a video signal from a bit map storage 14 is processed by differentiation box Kerr filters 20, 22. A coupling module 24 geometrically couples absolute values of values of edges of an image from the differentiation box Kerr filters 20, 22 in 2-dimension. A correlation module 26 obtains cross correlation of the coupled image in response to an infinite grid. This infinite grid has a Kernel corresponding to a block size of compression standards in use. The cross correlation value for each kernel is fed to a maximum value detector 28. A correlation value of each kernel is given to each range and a maximum value is obtained from correlation values for each range.

Title: Semiconductor device
Inventor: YOSHIDA MOICHI
IPC: H01L25/18
Filed: 1987-10-07
Abstract: PURPOSE:To enhance thermal resistance and insulating performance of an insulating substrate by a method wherein an intermediate material whose coefficient of thermal expansion is smaller than that of an extraction electrode is laid between a copper circuit sheet and the extraction electrode. CONSTITUTION:Intermediate materials 8a-8f whose coefficient of thermal expansion is smaller than that of extraction electrodes 5a-5f are soldered to upper circuit sheets 3a-3f; the extraction electrode 5a-5f are soldered to the intermediate materials. A thermal stress in the transverse direction due to a difference in a coefficient of thermal expansion between the extraction electrodes 5a-5f and an insulating substrate 2 is relaxed in the form of a slide in the transverse direction of solder layers on the surface and the rear surface of the intermediate materials 8a-8f because the coefficient of thermal expansion of the intermediate materials 8a-8f is smaller than that of the extraction electrodes 5a-5f. Accordingly, the insulating substrate 2 is not damaged due to the thermal stress of the extraction electrodes 5a-5f. By this setup, thermal resistance and insulating performance of the insulating substrate are enhanced.

IPC: G07F15/10
Filed: 1987-10-09
Abstract: PURPOSE: To allow the controller to surely collect the utility charge by allowing the user for a supplied material to use the supplied material with advance payment of the charge. CONSTITUTION: A storage medium D inserted to a medium insert port E is read by a read means F and the data are stored in a storage means G as supply amount data.

Simultaneously a data revision means conduct arithmetic processing to decrease the supply amount data by a supply amount detected by a supply amount detection means C. When the read means F reads the supply amount data from the storage medium D, an invalidate means H invalidates the storage content of the storage medium D. Thus, the switching control means I shuts the supply path A when the supply amount of a supply material represented by the supply amount data stored in the storage medium D is zero to use the supplied material only within a range of the supply amount represented by the supply amount data.
