Patent number: 5943134Abstract: A light beam emitted by a light source is projected through a collimator lens, a beam splitter and an objective on a sample having a laminated structure. The light beam reflected from the sample travels through the beam splitter to a detector and the detector provides a confocal signal. The detector provides an interference signal upon the reception of the reflected light beam and a reference light beam reflected by a reference mirror. The sample and the reference mirror are moved on the basis of the confocal signal and the interference signal, and the thickness and the refractive index of layer of the sample are determined on the basis of the respective displacements of the sample and the reference mirror.Type: GrantFiled: June 17, 1997Date of Patent: August 24, 1999Assignee: The Institute of Physical and Chemical ResearchInventors: Ichirou Yamaguchi, Takashi Fukano

Patent number: 4269323Abstract: A heat insulated tank is disclosed having inner and outer walls between which a supporting material is interposed. The material comprises a molding of alkaline earth metal silicates or a molding of composite material based thereon having a continuous open cell structure and subjected to heat treatment under vacuum. Inside and outside faces of said supporting material are provided with a suitable number of grooves. The entire surface of said supporting material is impregnated with a solution of sodium silicate, potassium silicate or ethyl silicate and subjected to baking.The supporting material has a high insulating capability and a high resistance to compression, thus it is applicable to square shaped tanks in addition to conventional spherical or cylindrical ones. The tank is easy to manufacture with increased storage capacity.Type: GrantFiled: October 2, 1978Date of Patent: May 26, 1981Assignee: Nippon Sanso Kabushiki KaishaInventors: Nobuyoshi Ito, Hiroshi Morishita, Minoru Morita, Takashi Fukano
