  • Patent number: 11148617
    Abstract: A sound insulating member includes a mass section and spring sections. The mass section is disposed so as to have a gap with respect to an outer panel which divides an internal space of a vehicle body and outside thereof, and includes at least a part which has a planar shaped form. The plurality of spring sections are disposed on the mass section at a side of the mass section facing an outer panel. Each of the spring sections has a hollow film member having airtightness and flexibility, and a gas sealed inside the film member. The film member has a first stepped section and a second stepped section that are formed in a stepped shape in an arrangement direction of the outer panel and the mass section.

  • Publication number: 20200290527
    Abstract: A sound insulation structure includes a mass part and a plurality of spring parts. The mass part is arranged to be spaced from a compartment member that compartmentalizes an internal space of a structure body and an outside. At least part of the mass part has a flat surface shape. The spring part is arranged on a side facing the compartment member in the mass part. The spring part includes: a hollow film material having airtightness and flexibility; and a gas encapsulated within the film material. The film material includes a recess part on one surface which is at least one of surfaces on the compartment member side and the mass part side.

  • Patent number: 10294497
    Abstract: An object of the present invention is to obtain fermentative yeast having highly efficient ethanol production without introducing a foreign gene. A further object is to obtain a fermentative yeast that is resistant to proliferation inhibitors such as organic acids, which prevent the proliferation of the fermentative yeast. Meyerozyma guilliermondii that can produce ethanol effectively from pentose and hexose was isolated by breeding. Moreover, resistance was imparted to the fermentative yeast by introducing transaldolase and alcohol dehydrogenase genes derived from Meyerozyma guilliermondii into the fermentative yeast.

  • Patent number: 10266003
    Abstract: Provided is a wheel which is inexpensive, light, and sufficiently rigid. A wheel 6a includes an annular rim 60 to which a tire 6b is externally fitted, a hub 61 which is arranged at a center portion of the rim 60 and to which an axle is connected, and a disk 62 which is attached with the rim 60 at a periphery portion and which covers one side of the wheel 6a. The disk 62 includes a planar portion 62a and a first rib 62b provided at a surface of one side of the planar portion 62a and extending in the radial direction. The planar portion 62a is provided with a first groove 62d at a surface of the other side at a position corresponding to the first rib 62b.

  • Patent number: 10131917
    Abstract: An object of the present invention is to obtain a fermentative yeast having a highly efficient ethanol production without introducing a foreign gene. A further object is to obtain a fermentative yeast that is resistant to proliferation inhibitors such as organic acids, which prevent the proliferation of the fermentative yeast. A yeast having an improved ethanol production ability was generated by introducing transaldolase and alcohol dehydrogenase genes by self-cloning to Meyerozyma guilliermondii that can produce ethanol effectively from pentose and hexose obtained by breeding, and further breeding the resultant yeast.
