Patent number: 10297244Abstract: Provided are: a carbonaceous acoustic matching layer which exhibits satisfactory mechanical strength, in which losses at a layer interface are suppressed as far as possible and in which the degree of variation in acoustic impedance in the thickness direction can be increased; and a method for producing same. The carbonaceous acoustic matching layer is obtained by dispersing filler particles, which are selected on the basis of the desired acoustic impedance of each layer, in a resin such as a furan resin, a phenol resin or a vinyl chloride resin, curing, laminating, and then carbonizing the resin by heating in a non-oxidizing atmosphere, amorphous carbon, which is obtained by the resin carbonization, is integrated across all the layers. The blending proportion of the filler particles is decided so that the difference in coefficient of linear contraction caused by the carbonization is at a minimum between adjacent layers.Type: GrantFiled: June 17, 2015Date of Patent: May 21, 2019Assignee: MITSUBISHI PENCIL COMPANY, LIMITEDInventors: Toshiki Oono, Atsunori Satake, Takeshi Suzuki

Patent number: 8544595Abstract: A carbonaceous acoustic diaphragm whose density is reduced while retaining the required stiffness is provided. Carbon nanofibers and spherical particles of PMMA are mixed into a carbon-containing resin such as a polyvinyl chloride resin, and the mixture is carbonized to vaporize the spherical particles of PMMA, thereby forming a porous structure having pores with the carbon nanofibers in a powdered form uniformly dispersed through amorphous carbon. By forming a multilayer structure by combining the porous layer with a layer that does not use PMMA, the density can be further reduced while retaining the stiffness.Type: GrantFiled: December 8, 2009Date of Patent: October 1, 2013Assignee: Mitsubishi Pencil Company, LimitedInventors: Takeshi Suzuki, Atsunori Satake, Noboru Kanba, Akihito Mitsui, Yoshihisa Suda

Patent number: 7264756Abstract: The invention provides at a relatively low cost a carbon substrate that is formed from an opaque material and that has an extremely flat surface so that optical measurements can be made on the substrate. Graphite powder with a particle size of 10 ?m or less is mixed in a thermosetting resin such as a furan resin, and the mixture is molded into a sheet and calcined at 1400° C. in an inert atmosphere to produce a carbon substrate whose surface is then ground flat.Type: GrantFiled: October 25, 2004Date of Patent: September 4, 2007Assignee: Mitsubishi Pencil Co., Ltd.Inventors: Yoshihisa Suda, Atsunori Satake, Kunitaka Yamada, Hiroko Kaneko, Kaoru Kato

Patent number: 5716151Abstract: A coating tool (12) comprises a coating tool body (2) having a liquid storage portion (2a) for storing a coating liquid, and a cap (10) detachably fitted and mounted on the coating tool body to be in tight contact with it. In the course of mounting the cap (10), the volume of a sealed space (A) formed in the cap (10) is decreased to supply air to the main barrel (2a), thereby pressurizing the interior of the main barrel (2a). At least one of an inner surface (10b1) of the cap (10) and an outer surface of a mouthpiece (2b) which are brought into tight contact with each other in the mounting operation of the cap (10) is coated with a sealing agent (16). In the coating tool for applying a correction liquid or the like, the ability to pressurize the interior of the liquid storage portion (2a) can be improved without complicating the structure in the cap (10), and the cap can be attached and detached smoothly.Type: GrantFiled: January 11, 1996Date of Patent: February 10, 1998Assignee: Mitsubishi Pencil Kabushiki KaishaInventor: Atsunori Satake
