Title: Electronic still camera
Inventor: OOTA YOSHITAKA
IPC: H04N5/335
Filed: 1983-12-29
Abstract: PURPOSE:To allow proper exposure control by providing a means which makes weighing for the photodetected amount differ at the center part and the peripheral part of a solid-state image pickup element. CONSTITUTION:For a douser 3 which is installed at the front surface of a CCD1, a hole 4 for passing light for only the center part is provided. Since a CCD1 is formed in this way, incident light irradiates only on the center part of the photodetecting part of the CCD1. Therefore, even if high luminance light falls on the peripheral part of the photodetecting part, it does not give the influence on the proper measurement of the photodetected amount. Therefore, proper exposure setting is executed. After executing weighing according to the position of the screen by using the douser 3 and calculating the amount of exposure, the douser 3 is removed at the time of reading of actual picture information. For the methed which makes weighing differ, the overflow drain may be devided into the center part and the peripheral part. Thus, proper exposure control is executed.

Title: Method for evaluating creep damage of non-uniform deformed pipe
Inventor: TAMURA KOJI
IPC: G01N3/00
Filed: 1988-10-04
Abstract: PURPOSE:To evaluate the calculation of the real bulge rate in the region advance in creep deformation of a pipe by setting a coordinate system consisting of a long diameter axis and a short diameter axis to judge a creep advanced region. CONSTITUTION:The center O of gravity of the contour 2 of the outer diameter of the cross-section of a heat transfer pipe 1 having generated creep deformation is set to the center point of a rotary shaft to calculate a straight line (long diameter axis) AB becoming the max. diameter. By this method, one of two intersecting points of the straight line and the outer periphery of the pipe is detected as a region where creep deformation is advanced. Further, the straight line (short diameter axis) CD becoming the max. diameter in the direction right-angled to the straight line AB is calculated. The intersecting point O' of the straight lines AB, CD becomes the position corresponding to the center in such a case that the heat transfer pipe 1 is uniformly deformed. In the case of AO' > BO', a point A can be judged to be a part becoming max. in creep deformation. Therefore, the max. diameter around the point O' is determined and this max. diameter is used to calculate a bulge rate and creep damage can be evaluated safely.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound free from byproducts and odorous components, and useful as a surfactant for cosmetics or the like by acylating a protein (its hydrate) with an acylating agent using at least 2-propanol as a solvent. SOLUTION: In a process where a protein (e.g. an edible gelatin) or a protein hydrate is acylated with an acylating agent such as a fatty acid halide (e.g. lauric chloride), the acylation is carried out by using at least 2-propanol as a solvent, and further by adding propylene glycol besides 2-propanol as a solvent. Subsequently, at an arbitrary stage after the completion of the acylation with an acylating agent, the reaction system is acidified and washed with water or propylene glycol is added to the reaction product, and the system is degassed under reduced pressure. Thus, the objective acylated peptide expressed by the formula [R<1> is a hydrocarbon; R<2> is a side chain of an amino acid; M is H, a metal atom or ammonium; (n)>=1] useful as a surfactant, etc., useful as a toiletry product or a cosmetic.
