Title: Ph sensitive solid-state material
Inventor: YOTSUYANAGI TAKAO
IPC: C09K3/00
Filed: 1987-12-04
Abstract: PURPOSE:To make it possible to discolor a material in an arbitrarily specified pH range with porphylin having a high mol extinction coefficient as a pH indicator, by supporting and fixing hydrophobic porphylin with water-insoluble macromolecules, and the like. CONSTITUTION:Hydrophobic porphylin is supported and fixed with water- insoluble macromolecules. Or the hydrophobic porphylin and an organic material having positive or negative electric charge are supported and fixed with the water-insoluble macromolecules together. Thus a pH sensitive solid-state material is obtained. As the method for manufacturing the pH sensitive thin film, the water-insoluble macromolecules are dissolved into a solvent such as tetrahydrofuran. This material and porphylin are added. The organic material having the positive or negative charge is further added as required. Thereafter, this is developed on a transparent resin plate, a glass plate or the surface of water. This method is simple. Thus, a very thin film is obtained. In this way, discoloration can be performed in an arbitrarily specified pH range, with porphylin having a high mol extinction coefficient as a pH indicator.

IPC: G06T11/40
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To accurately paint out a closed region even when coordinate data expressing the boundary pixels of the closed region are given discontinuously. SOLUTION: Concerning a closed region designated by the coordinate values of boundary pixels, plotting of the given boundary pixels is executed, coordinates constituting plotting data are sorted to groups of the same Y coordinates while retaining their X coordinates. The respective Y-coordinates are rearranged by the magnitude of retained X-coordinates to delete coordinates constituting the boundary concerning the Y-direction among them and to retain the others. Concerning the even number of X-coordinates retained, pixels between an odd- numbered X-coordinate to an even-numbered X-coordinate are plotted. The closed region given by the boundary pixel data is painted out by executing this operation concerning all of the Y-coordinates.

Title: Method for presuming proper welding voltage
Inventor: IMATAKA TOSHIYUKI
IPC: B23K9/06
Filed: 1988-12-08
Abstract: PURPOSE:To presume the proper welding voltage having high correlation by applying a specific regression expression different for each range before and behind a changing point in the case the measured welding voltage has the changing point. CONSTITUTION:In the presuming method of the proper welding voltage, a regression coefficient V'si of the regression expression expressed by the expression 1 is obtained from a welding current Is and the welding voltage Vs. A correlation coefficient (r) expressed by the expression 2 is then calculated with respect to various values of M of the search range. The regression coefficient V'si when an absolute value of the correlation coefficient (r) becomes maximum and the values of M are then used to determine the regression expression to calculate the proper welding voltage. Accordingly, in the case the measured welding voltage Vs has the changing point, the primary regression expression different for each range before and behind the changing point is applied, by which even if there is the changing point, the primary regression expression to obtain the optimum welding voltage having the high correlation coefficient (r) is still obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a wiper device capable of suppressing or preventing looseness in the case of using a long-sized wiper blade and ensuring the smooth rotation of a wiper blade in the case of using a winter blade or the like. SOLUTION: A selective axial hole 36 and a reference axial hole 38 are formed in a clip 20, and the reference axial hole 38 is spaced farther from a curved part 24 of the clip 20 than the selective axial hole 36.
