Publication number: 20140333194Abstract: A light source device comprising a filament showing high electric power-to-visible light conversion efficiency is provided. A light source device comprising a translucent gastight container, a filament disposed in the translucent gastight container, and a lead wire for supplying an electric current to the filament is provided. The filament comprises a substrate formed from a metal material and a visible light reflectance-reducing film coating the substrate for reducing visible light reflectance of the substrate. The reflectance of the substrate for visible lights is thereby made low, and the reflectance of the substrate for infrared lights is thereby made high. Therefore, radiation of infrared lights is suppressed, and visible luminous efficiency can be enhanced.Type: ApplicationFiled: November 30, 2012Publication date: November 13, 2014Inventors: Takahiro Matsumoto, Takao Saito, Yasuyuki Kawakami

Publication number: 20120121817Abstract: Provided is a method of manufacturing a DLC film formed body in which peeling-off of a DLC film is suppressed. In manufacturing a DLC film formed body having a film hardness of 10 GPa or more, prior to the formation of the DLC film, a surface of a base is pretreated with a discharge plasma and a silicon carbide film being an interlayer is formed on the surface of the base. The surface of the base is pretreated by supplying an inside of the chamber with a gas mixture obtained by mixing 1 part by volume or more and 10 parts by volume or less of argon gas into 100 parts by volume of helium gas while adjusting a pressure inside of the chamber in which the base is housed to 20 hPa or higher and an atmospheric pressure or lower, and generating a discharge plasma in the mixed.Type: ApplicationFiled: December 20, 2011Publication date: May 17, 2012Applicant: NGK Insulators, Ltd.Inventors: Takao Saito, Tatsuya Terazawa

Patent number: 7927982Abstract: A silicon-based thin film mass-producing apparatus, including transparent electrodes placed to face in parallel to corresponding counter electrodes with a space therebetween, and silicon-based thin films are deposited on the transparent electrodes by feeding a raw material gas for depositing the silicon-based thin films into the chamber and by applying a DC pulse voltage to the counter electrodes to generate plasma. Unlike methods in which a radio frequency voltage is intermittently applied to perform discharge, a high plasma density distribution does not occur, and in-plane film thickness distribution does not occur. Furthermore, since the DC pulse voltage rises sharply, the ON period can be shortened. As a result, generation of a sheath ceases in the transient state before reaching the steady state, and the thickness of the sheath is small, which allows the space between the counter and transparent electrodes to decrease.Type: GrantFiled: March 26, 2009Date of Patent: April 19, 2011Assignee: NGK Insulators, Ltd.Inventors: Minoru Imaeda, Yuichiro Imanishi, Takao Saito

Patent number: 7927981Abstract: A silicon-based thin film depositing apparatus, including a plurality of transparent electrodes disposed to face corresponding counter electrodes with a space therebetween. Subsequently, while injecting a raw material gas from raw material gas injection orifices toward the supporting electrodes and also injecting a barrier gas from barrier gas injection orifices in the same direction as the direction in which the raw material gas is injected, the gases are discharged from a gas outlet, and thereby, the pressure in a chamber is controlled to a pressure of more than 1 kPa. Then, a DC pulse voltage is applied to each counter electrode to deposit a silicon-based thin film. A DC pulse voltage is applied to perform discharge. Therefore, even in a state where the distance between the electrodes is increased, plasma can be generated efficiently, and the in-plane distribution of film thickness can be improved.Type: GrantFiled: March 26, 2009Date of Patent: April 19, 2011Assignee: NGK Insulators, Ltd.Inventors: Minoru Imaeda, Yuichiro Imanishi, Takao Saito

An amorphous carbon film is formed by supplying a mixed gas between the supporting electrode and the counter electrode such that the percentage of the acetylene gas relative to the carrier gas is 0.05% by volume or more and 10% by volume or less, and by generating plasma while a DC pulse voltage having a pulse width of 0.1 ?sec or more and 5.0 ?sec or less is applied to the counter electrode.Type: GrantFiled: March 3, 2009Date of Patent: April 12, 2011Assignee: NGK Insulators, Ltd.Inventors: Takao Saito, Tatsuya Terazawa
