Publication number: 20200367423Abstract: A long base sheet is a thin paper like toilet paper, made of water-decomposable paper, and is supplied from a base sheet supply section. A water-soluble adhesive is applied to a surface of the sheet at a predetermined interval in an adhesive applying section. Multiple seeds are placed on the surface of the sheet, and then the sheet is put up to non-adhering remove seeds. Thereafter, in a base sheet transportation/seed pressing section, the sheet is pressed by a pair of rollers and softer than the seed, producing a seeded paper. In the seeded paper, concave portions are on the long base sheet, and have a plane shape approximately equal to a shape of the target seed and depth of one tenth to equal to a height of the target seed, and the target seed adheres to an inside area of each of the concave portions by the water-soluble adhesive.Type: ApplicationFiled: May 10, 2018Publication date: November 26, 2020Applicant: ELM INC.Inventors: Takakazu MIYAHARA, John Cedric Villanueva OBAG

Patent number: 9220144Abstract: A time-division control circuit individually controls an effective voltage supplied to each lighting load by adjusting the periods during which switching circuits connected to N sets of lighting loads are kept on. A zero-cross signal having a value that changes at the zero-cross point of the AC voltage is generated. An oscillation signal is generated with a frequency equal to, or an integer multiple of the AC frequency. The phase difference between the zero-cross signal and the oscillation signal is measured and a common reference point that defines the timing for turning the switching circuits ON or OFF is determined on the basis of the measured phase difference. An ON/OFF signal for each switching circuit is transmitted at a timing for each of the N sets of switching circuits on the basis of the reference point and the effective voltage to be supplied to the lighting load.Type: GrantFiled: May 14, 2013Date of Patent: December 22, 2015Assignee: ELM INC.Inventors: Takakazu Miyahara, Hiroshi Kirihara, Mitsuhiro Hashiguchi

Publication number: 20130181465Abstract: After a scratch 160 or similar defect formed on the readout surface of an optical disc is nearly completely removed by grinding and polishing the readout surface with surface with a grinding/polishing agent or similar compound, the readout surface is coated with a coating agent 170 made of a transparent resin or similar material. In this process, a significant change in the thickness of the optical disc before and after the restoration can be prevented by controlling the grind/polishing and coating processes so that the decrease in the thickness due to the grinding/polishing is nearly equal to the increase in the thickness due to the application of the coating agent 170. Therefore, even a Blu-ray Disc or similar optical disc having only a small distance from the surface to the information record layer can be restored many times.Type: ApplicationFiled: January 17, 2012Publication date: July 18, 2013Applicant: ELM INC.Inventors: Takakazu MIYAHARA, Terumasa MIYAHARA, Kengo WADA

Patent number: 8342905Abstract: An optical disk restoration apparatus and optical disk restoration method are provided, which are capable of achieving a high level of capability of restoring a scratched optical disk, without consuming the time and labor of an operator, while reducing the production cost of the apparatus. During a polishing process, an appropriate amount of a polishing agent is dropped onto the readout surface of the optical disk by a polishing agent supply pump to continuously supply the polishing agent to the interface between the optical disk and polishing pads, while a polishing water supply pump is operated to replenish the polishing agent with moisture evaporated by the polishing heat. By this mechanism, the amount and physical properties of the polishing agent at the interface between the optical disk and the polishing pads are appropriately maintained for a long period of time, so that the restoration capability is maintained at high levels.Type: GrantFiled: August 31, 2009Date of Patent: January 1, 2013Assignee: Elm Inc.Inventors: Takakazu Miyahara, Terumasa Miyahara, Kazutoshi Chijiiwa

Publication number: 20120206927Abstract: An LED lighting apparatus includes an LED-mounting base having LED elements mounted on its surface and a heat-dissipating section fixed on the back side of the LED-mounting base. The heat dissipating section is provided with: a core having a sealed space and heat-dissipating fins provided around the core. Thus, an LED lighting apparatus which has a shape substantially the same as that of a large mercury lighting apparatus, and which can efficiently dissipate heat generated from the LED elements, with only the smallest increase in the weight of the apparatus, can be provided. The electronic-circuit housing section may contain an electric circuit for generating power to be supplied to the LED elements. Furthermore, it is desirable to leave a small space in the electronic-circuit housing section so as to absorb the expansion of the cooling liquid, rather than completely fill the electronic-circuit housing section with the cooling liquid.Type: ApplicationFiled: October 26, 2010Publication date: August 16, 2012Applicant: ELM INC.Inventor: Takakazu Miyahara

Patent number: 7857951Abstract: The present invention intends to provide a water purification apparatus that is small and easy-to-use, yet being capable of efficiently creating flocs of impurities and removing the impurities from the wastewater in a single pass. To achieve this objective, an inner tubular anode 12 made of stainless steel or carbon is inserted into an outer tubular cathode 11 made of aluminum, leaving a predetermined intermediate space 13 between them, and electrolysis is carried out to produce aluminum hydroxide. The aluminum hydroxide thus produced serves as the medium for flocculating the impurities in the wastewater ascending the intermediate space 13. The wastewater containing the flocs of impurities is filtrated with a filter 18 within a filtering and settling tank 17. As a result, the impurities are completely removed from the wastewater.Type: GrantFiled: May 20, 2004Date of Patent: December 28, 2010Assignee: Elm Inc.Inventors: Takakazu Miyahara, Terumasa Miyahara
