CONSTITUTION:The structure to satisfy the following optical characteristics (lambda1<lambda2) for the two wavelengths lambda1, lambda2, is determined: The structure has the reflectivity 20%<= R10 <=50%, 15%<=(R10-R11)<=30%, 58% R2o, 40%<=(R20-R21), where R10 is the reflectivity of the unrecorded part to the wavelength lambda10; R11 is the reflectivity to the wavelength lambda1 of the recording marks formed by the irradiation with the laser beam. Protective layers 2, 9, a recording layer 3, a protective layer 4 and a reflection layer 5 are successively formed on a substrate and further, the same PC disk is stuck as the protective substrate 7 by an adhesive 6 thereto. The optical constants of the respective layers are measured. The reflectivity over the entire part of the recording medium is calculated when the film thicknesses are changed from such data, by which the optimum film thickness constitution is determined. The absorbance of light is determined from the energy balance of light at the respective boundaries, by which the variations are eliminated.

Filed: 1990-01-29
Abstract: PURPOSE:To plot a smooth curve by means of free hands by inputting a picture by means of the free hands and calculating a centroid point from the coordinate. CONSTITUTION:The index (n) of the inputted coordinate and the index N of the centroid point are respectively initialized to '0', and coordinate input from an input part 1 is checked through a coordinate analysis part 21. When there is no coordinate input, a processing is proceeded and it is checked whether prescribed time has passed or not. If prescribed time has passed, it is assumed that the plotting curve reaches a final point and the processing is terminated. If prescribed time has not passed, the processing is started and whether there is coordinate input or not is checked. When the coordinate is inputted from the input part 1 through the analysis part 21, the processing is proceeded and the index (n) is increased. Then, it is checked whether or not the index (n) is n>=20, namely, whether or not there are inputs more than twenty times from the beginning and it is the multiple of five. Then, the initial centroid point (X1, Y1) is calculated from the coordinates (x0, y0)-(x19, y19), the coordinate is inputted at every five times and the centroid point is calculated from the coordinates for previous twenty times.

Abstract: PROBLEM TO BE SOLVED: To suppress graying of part of a bulb in an inexpensive and easy manufacturing method by applying a solution of an inorganic compound onto the inner wall of the bulb so as to form a transparent layer, followed by enclosure of mercury and noble gas. SOLUTION: A transparent layer 5 applied onto the inner wall of a glass tube 1 includes at least one of oxides of trivalent rare earth elements such as Nd, Pm, Dy, Ho, Er and Tm, although it may include Y2 O3 . Consequently, it is possible to prevent ionized mercury from intruding into the glass during lighting of a lamp, so as to suppress corrosion. Preferably, a solution prepared by adding dried nitrocellulose and ethylene glycol in a small quantity into a methanol solution of yttrium nitrate hexahydrate is sprayed and applied to the inner face of the glass tube 1, followed by air drying, so that the transparent layer 5 is formed by baking the resultant solution at about 600 deg.C or higher. Subsequently, an ultraviolet lamp is manufactured by a normal method.  Yttrium nitrate hexahydrate is more inexpensive than an organic metal compound, and further, methanol is inexpensive and easy to be dried and decomposed.

Title: Atmospheric pressure detecting apparatus for internal combustion engine
Inventor: KAWASAKI SHINGO
IPC: F02D45/00
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To conduct atmospheric pressure detection even in medium or low load operational state of an internal combustion engine, and to reduce error between obtained atmospheric pressure and present atmospheric pressure. SOLUTION: Intake air pressure or atmospheric pressure is introduced into a back pressure chamber of a pressure control valve 30, resulting in generating differential pressure in fuel pressure on an fuel injection valve 5 based on difference between the intake air pressure and the atmospheric pressure. The differential pressure emerges as the change of a fuel injection amount from the fuel injection valve, and is calculated as an air-fuel ratio F/B(feed back) correction coefficient based on each output from an air-fuel ratio sensor 12. Thereby, the intake air pressure sensed by an intake air sensor 11, the air-fuel ratio F/B correction coefficient, and set pressure of the pressure control valve 30 are found, so that the atmospheric air pressure is calculated.  Accordingly, the atmospheric air pressure of an internal combustion engine 1 is calculated not only in a conventional high load operational state but also in a medium or low operational state. Error between the atmospheric pressure obtained by atmospheric pressure detection processing and the present atmospheric pressure is reduced to improve reliability.
