Patent number: 11942575Abstract: The embodiment provides a transparent electrode having low resistance and high stability against impurities such as halogen and sulfur, a method of producing the transparent electrode, and an electronic device using the transparent electrode. A transparent electrode according to an embodiment includes a transparent substrate and a plurality of conductive regions disposed on a surface of the transparent substrate and separated from each other by a separation region, wherein the conductive region has a structure in which a first transparent conductive metal oxide layer, a metal layer, and a second transparent conductive metal oxide layer are laminated in this order from the substrate side, and in the separation region, there is disposed a trapping material. This transparent electrode can be produced by scribing the conductive region to form a separation region, and then using a halide or a sulfur compound.Type: GrantFiled: February 28, 2022Date of Patent: March 26, 2024Assignees: KABUSHIKI KAISHA TOSHIBA, TOSHIBA ENERGY SYSTEMS & SOLUTIONS CORPORATIONInventors: Katsuyuki Naito, Naomi Shida, Yutaka Saita

Patent number: 7394532Abstract: A method and an apparatus of inspecting the surface of a wafer, where two or more kinds of laser are switched or mixed to make the laser incident on the film-coated wafer by a same incident angle, in which inspection data regarding an inspection apparatus and film parameters regarding a film are stored in storage means of the inspection apparatus in an associated state with each other so as to obtain predetermined inspection conditions. When performing each measurement, an operator sets the film parameters of the wafer to be measured by setting means of the inspection apparatus. Thus, desired inspection conditions are automatically set in the inspection apparatus. The film parameters that the operator sets at each measurement are a film thickness and a film refraction index.Type: GrantFiled: October 8, 2003Date of Patent: July 1, 2008Assignee: Kabushiki Kaisha TopconInventors: Hisashi Isozaki, Michihiro Yamazaki, Hiroshi Yoshikawa, Takehiro Takase, Yutaka Shida, Yoichiro Iwa

Patent number: 6402064Abstract: Granular substances with pollutants adhered, such as contaminated soils and incinerated ashes, are finely granulated to separate the pollutants from the granular substances efficiently and to enable the granular substances, from which pollutants have been separated, to be recycled. After fine granulation of the granular substances by a coarse disintegrating treatment through a first fine granulation machine, the granular substances, which have been finely granulated by the first fine granulation machine, are subjected to, by a second fine granulation machine, mutual polishing among the granular substances by mutual rubbing forces of the substances themselves and thus the pollutants, such as heavy metals and dioxin class substances adhering strongly to the surfaces of the granular substances, are separated, and also the granular substances not containing the pollutants are classified from the granular substances which have already been finely granulated by a vibrational screen and a classification device.Type: GrantFiled: October 21, 1999Date of Patent: June 11, 2002Assignees: Shinroku Seiki Kabushiki Kaisha, Youyu Shigen Kabushiki Kaisha, Kabushiki Kaisha KamagaigumiInventors: Takao Tango, Yo Ito, Hirohiko Shibata, Kenji Kawaguchi, Yutaka Shida
