Patent number: 6814239Abstract: An apparatus for producing high-purity standard particles produces nanometer-sized high-purity standard particles of monodispersive uniform structure efficiently, with the abatement of contamination and damage. The apparatus includes a particle generation chamber, a particle classification chamber and a particle collecting chamber. The particle generation chamber excites a semiconductor target with pulse laser beam under a low-pressure rare gas ambient so as to detach and eject materials from the target into the ambient gas, in which those materials are condensed and grow into high-purity particles. The particle classification chamber subjects the high-purity particles as generated to classification, and the particles collecting chamber collects high-purity standard particles as classified onto a substrate.Type: GrantFiled: February 15, 2002Date of Patent: November 9, 2004Assignee: Matsushita Electric Industrial Co., LTDInventors: Nobuyasu Suzuki, Takehito Yoshida, Toshiharu Makino, Yuka Yamada

Patent number: 6809314Abstract: A fine-particle classification apparatus includes an aerosol generation section which generates an aerosol containing fine particles in a medium background gas, a fine-particle classification section which classifies the fine particles contained in the aerosol in a sheath gas, and an introduction section, between the aerosol generation section and the fine-particle classification section, which introduces the aerosol generated in the aerosol generation section into the fine-particle classification section. The introduction section uses a carrier gas with an adequately high velocity to introduce the aerosol generated in the aerosol generation section to the classification section using a pressure difference.Type: GrantFiled: August 10, 2001Date of Patent: October 26, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takehito Yoshida, Toshiharu Makino, Nobuyasu Suzuki, Yuka Yamada

Publication number: 20040151672Abstract: A particle counter counts particles in aerosol having a particle size of from 2 nm to 50 nm in an operating pressure range from an atmospheric pressure through a reduced pressure to a low vacuum and calculate a particle size distribution. The particle counter charges particles in the aerosol and applies an electrostatic field thereto, and mixes the aerosol with a non-charged sheath gas flow shaped like a laminar flow whereby the respective particles separate into traces depending on their particle size where they can be counted. Further, by using an electron multiplier for exciting cluster ions to detect the charged particles and operating it as a high-pass filter, even if the number density of the particles is small, it is possible to effectively count the particles.Type: ApplicationFiled: January 23, 2004Publication date: August 5, 2004Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Takehito Yoshida, Nobuyasu Suzuki, Toshiharu Makino, Yuka Yamada

Publication number: 20040141537Abstract: In fabricating a monochromic and highly coherent light source, no single crystalline bulk semiconductor is used, but two different kinds of transparent substances are alternately stacked over each other to constitute a periodic structure in ½ of the intended wavelength. At least one of the two kinds of transparent substances is controllable in electric conductivity, and the structure is such that inside a medium consisting of this kind of transparent substance light-emitting semiconductor particulates are embedded. Accordingly, a light-emitting device has this structure, which makes possible control of the center wavelength of light emission, the width of wavelength distribution and coherence by adjusting the geometrical parameters of the device without having to alter the kind of material use.Type: ApplicationFiled: January 12, 2004Publication date: July 22, 2004Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Takehito Yoshida, Yuka Yamada, Nobuyasu Suzuki, Toshiharu Makino
