Title: Image processor
Inventor: AOYAMA TAKANARI
IPC: G06F12/00
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To reduce noise due to a high-speed clock signal, while meeting the requirements of high-speed operation and low power consumption by controlling the state of a clock enable signal supplied to a synchronous DRAM in timing to the input and output of image data and controlling the operation stop and start states of a clock signal. SOLUTION: An image processing part 2 functions to write image data to a synchronous DRAM(SDRAM) 1 at a drawing request from a CPU 11 or read the image data out of the SDRAM1 at an output request. This device controls the state of the clock enable signal supplied to the SDRAM 1, in response to the input and output of the image data to and from the SDRAM1 used as a page memory and also controls the operation stop and start states of the clock signal supplied to the SDRAM1. Consequently, while no access request to the SDRAM1 is generated, the clock signal is in the operation stop state, and the clock signal will be transmitted only during the period required.

Title: Standard sample
Inventor: TAKENAKA HISATAKA
IPC: G01N23/22
Filed: 1993-08-26
Abstract: PURPOSE:To accurately evaluate a solving power of an Auger electron spectral analysis method and a secondary ion mass analysis method by laminating a layer comprising amorphous or polycrystalline material several times to make a standard sample. CONSTITUTION:The use of a layer comprising amorphous or polycrystalline material minimizes the anisotropy to allow the formation of a standard sample of a laminated film with a higher degree of homogeneity. The etching of the sample can reduce problems of changes and increase in surface roughness in etching rate depending on the direction and angle of incidence of ions for etching of a crystal axis. When a film of such a lamination structure is applied as standard sample for an Auger electron spectral analysis and a secondary ion mass analysis method, the relationship can be determined between the angle of incidence and the accuracy of element concentration distribution in and the direction of depth. The accuracy intrinsic to the analysis methods can be obtained when other material is analyzed.
