Title: Method for detecting position of flying ink droplet
Inventor: KUDO OSAMU
IPC: B41J2/125
Filed: 1987-03-04
Abstract: PURPOSE:To enhance the detection accuracy of a flying ink droplet, by detecting the position of the flying ink droplet in an up-and-down direction on the basis of the positions of some points imparting no effect of various parameters in the horizontal direction and the spatial positional relation between a light source part and a light receiving means. CONSTITUTION:A plurality of sensors 30 each consisting of a light source part 10 and a pair of light receiving means 20 opposed thereto are arranged in front of a plurality of nozzles 1 in a row along the arrangement direction of the nozzles 1. The output difference between a pair of the light receiving means 2 of each sensor 30 is calculated while the voltage for charging ink is changed to successively change the deflection quantity of the ink flying from each nozzle 1. The charge voltage value at the point of time when said output difference takes a predetermined state is calculated and, on the basis of said voltage value, the coordinates position of the point, where the boundary surface of the detection region of the sensor 30 and the outside of said region crosses the deflection locus of the ink, in the horizontal direction is calculated and, on the basis of said position and the spatial coordinates position of the boundary surface, the position relating to the up-and-down direction of the ink is detected. By this method, the position of the flying ink droplet in the up-and-down direction can be detected with sufficient accuracy.

Abstract: PURPOSE:To improve water resistance, by using a specified phenol compound as a developer for a leuco dye. CONSTITUTION:As the developer for a normally colorless or light-colored leuco dye of e.g., triphenylmethane or fluoran series, a phenol compound of formula I (wherein R<1> and R<2> are each a 1-3C alkyl group), e.g., bis (2,5-dimethyl-4- hydroxyphenyl) sulfide, wherein R<1> and R<2> are methyl, is compounded to form a heat-sensitive color forming layer. In general, a dye solution containing the leuco dye, a developer solution containing the phenol compound, and a filler solution are prepared, mixed, applied on paper as a support, and dried. Then calendering is performed to smooth the surface. The obtained heat-sensitive recording sheet has an excellent water resistance and gives stable recorded image.

Abstract: PURPOSE:To inexpensively and easily enhance the luminous or light detecting  efficiency, by coating organic resin film having required refractive index over  the light emitting or receivig surface of a light emitting device or photo detector. CONSTITUTION:An organic resin film 17 having required refactive index is coated over a part of the light receiving surface of a photosemiconductor element, e.g. photo detector 25. For example, polyimide resin film with the refractive index 1.9 is used for the resin film 17.

IPC: G11B7/135
Filed: 1986-03-07
Abstract: PURPOSE:To decrease the phase difference between S- and P-polarized light by using a band pass filter consisting of multi-layered dielectric films as a separating and synthesizing element for two wavelengths. CONSTITUTION:High refractive index lambda/4 layers 11 consisting of TiO2, etc. and low refractive index lambda/4 layers 12 consisting of SiO2, etc. are alternately laminated on a substrate 10 consisting of glass, etc. and low refractive index lambda/2 layers 13 consisting of SiO2, etc., are interposed therebetween to constitute this band pass filter. The transmittance of this filter is nearly 100% near, for example, 780nm and the reflectivity is nearly 100% near 830nm with both S- and P-waves, thus the filter functions to separate and synthesize the wavelengths. The phase difference in these wavelength regions are extremely small. The deterioration of the C/N ratio occurring in the phase difference of the S- and P-polarized light is, therefore, suppressed if such filter is used.
