Title: Method for taking-up metallic band
Inventor: ARANAKA TAKAAKI
IPC: B21C47/30
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To execute positioning accurately by controlling so that the tip of a metallic band is overlapped on the stepped position of a take-up mandrel, taking-up a small number of turns, interrupting winding, expanding the diameter of the mandrel till the tip of the metallic band coincides with the stepped position and restarting winding. SOLUTION: Positioning control is executed so that the stepped position 8a of the stepped sleeve of the take-up mandrel 8 is slightly overlapped on the tip 1a of the metallic band. It is preferable to make the amount of overlap of the tip 1a of the metallic band with the stepped position 8a as smaller as possible, but the overlap is made to be always plus by setting it in the range beyond control error. After 1.1 to 2 turns of the metallic band are wound, winding is interrupted. Until the tip 1a of the metallic band coincides with the stepped position 8a, the diameter of the take-up mandrel 8 is expanded in the direction of the arrow 24. Coincidence of the tip 1a of the metallic band with the stepped position 8a is detected and the winding of the metallic band 1 is restarted as holding the diameter of the take-up mandrel 8.

IPC: G03C1/498
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To facilitate image appreciation and to prevent occurrence of interference fringes on an image by specifying the absorbance range of a support in an exposure wavelength and an average silver halide size range in a photosensitive silver halide emulsion layer formed ion the support. SOLUTION: The support of the photosensitive material to be exposed to laser beams has an absorbance of >=0.3 in the exposure wavelength and that of <=0.2 in the wavelength of 500nm, and the photosensitive silver halide emulsion layer formed on the support has an average grain size of 0.01-0.4μm, thus permitting the photosensitive material for laser beams to be good in the transparence of the support and to be facilitated in image appreciation and to prevent occurrence of interference fringes. When the absorbance of the support in the exposure wavelength is less than 0.3, the interference fringes occur and when the absorbance at 500nm exceeds 0.2, the transparence of the support becomes insufficient.

Abstract: PURPOSE:To form high pressure resistive gate oxide film on a semiconductor device by developing epitaxial layer on a silicon wafer prepared using the CZ method, followed by applying to the CZ wafer the low temperature and short period heat treatment and then high temperature and long period heat treatment that stimulate the deposition of oxygen within the CZ wafer. CONSTITUTION:On a single crystal silicon wafer 1 prepared using the CZ method and epitaxial layer 2 is formed. After that, when low temperature and short period heat treatment is applied at 900 deg.C for 1Hr to the CZ silicon wafer 1 in a nitrogen atmosphere, deposition cores 3 are formed inside the CZ silicon wafer 1. Next, high heat treatment and long heat treatment is further applied at 1100 deg.C for 16Hr to the CZ silicon wafer in the nitrogen atmosphere, oxygen is getting deposited on the deposited cores 3 formed by the 900 deg.C heat treatment to form oxygen deposit 3a thereon. On the other hand, the oxygen in the epitaxial layer is diffused outward and as a consequence oxygen is further removed from the element forming area. In addition, a gettering site 3a for impurity is formed in the ground of CZ wafer 1 to getter the impurities, thus removing impurities such as heavy metal from the gate oxide film formed area. Thus, high pressure resistive, highly reliable gate oxide film can be prepared.

Title: Data processing method
Inventor: OKAMURA HISASHI
IPC: G06F11/08
Filed: 1979-11-26
Abstract: PURPOSE: To make it possible to improve the reliability of data communication further by detecting the destruction of data of each element by using as a check code the sum of values a 1 Wa n  of respective elements and a constant value.  
     CONSTITUTION: A check code within a transmission unit or record unit is denoted as CCD 2  and the sum of values a 1 Wa n  of elements 1W(n) and a constant value (where the number (n) of respective elements is used), i.e. CCD 2 =a 1 +a 2 +W +a n +n is used. As a result, when data having the constitution shown in the figure with regard to the transmission unit or record unit are processed, check code CCD 2  is not zero since even if all elements are zero owing to malfunction of software, check code CCD 2  shows the number (n) of elements, so that data destruction detection regarding whether data of each element is destroyed or not can be performed. Thus, the reliability of data transmission can be improved more.
