Patent number: 8299344Abstract: A key having a key-depression surface with a woody characteristic and durability without the need of a surface treatment and capable of being formed from a simple-shaped uncompressed wood. A key for use as a black key includes a resin part and a compressed wood part secured at its lower surface to an upper surface of the resin part. The compressed wood part is used to constitute a portion of a key top including an upper surface and positioned above an upper surface of white keys which are in a non-key-depression state. The compressed wood part is obtained by compression molding of unprocessed wood. The compressed density in the vertical direction in the compressed wood part is higher toward rearward from a front end of the compressed wood part.Type: GrantFiled: January 10, 2011Date of Patent: October 30, 2012Assignee: Yamaha CorporationInventors: Ichiro Osuga, Hiroyasu Abe

Publication number: 20100005946Abstract: A drum shell is constituted of at least one laminate wood in which at least one fiber-reinforced layer (e.g. a carbon fabric) is inserted between two wooden materials via the adhesive and which is rolled up in a cylindrical shape. By setting the mass per unit area of the fiber-reinforced layer ranging from 5 g/m2 to 75 g/m2, it is possible to prevent the detachment of fibers inside the fiber-reinforced layer while controlling the shearing loss with respect to the laminate wood. The drum shell is equipped with at least one drumhead so as to produce a drum with a high sound quality and with a fine-grained exterior appearance.Type: ApplicationFiled: June 18, 2009Publication date: January 14, 2010Applicant: YAMAHA CORPORATIONInventors: Toshitaka Yoshino, Yukimasa Okumura, Hiroyasu Abe, Takuya Abe, Hironao Nagashima

Patent number: 6838604Abstract: A prescribed number of bars are arranged in a percussion instrument such as a xylophone and marimba, wherein each bar is formed by a base layer, a fiber reinforced plastic layer, and a surface layer that are combined together using an epoxy adhesive therebetween. Both the base layer and surface layer is made of the prescribed hardwood material such as rosewood, hard birch, padauk, and Chinese quince, while the fiber reinforced plastic layer is formed by laminating one or more fiber reinforced plastic sheets, each of which is formed by impregnating and hardening thermosetting epoxy resin with fibers. All fibers can be aligned in a single direction slanted to the longitudinal direction of the bar. Alternatively, fibers are woven in two directions rectangularly crossing each other in a cloth form. Thus, it is possible to improve bars in striking durability as well as in sound quality and design.Type: GrantFiled: September 6, 2002Date of Patent: January 4, 2005Assignee: Yamaha CorporationInventors: Hiroyasu Abe, Masayuki Kato, Yasumasa Shimizu, Yasuyuki Semba

Publication number: 20040108017Abstract: The present invention provides a method of manufacturing wood elements for musical instruments that have vibration characteristics similar to those of natural woods that are used for musical instruments. The method comprises a laminating step in which a resin is coated onto or is impregnated into a plurality of wooden plate units, fiber directions of the wooden plate units are aligned, and the wooden plate units are stacked and are subjected to thermal pressing so as to be bonded together and produce a laminated body, wherein the thermal pressing is conducted by controlling a pressure so that a density of the laminated body is in a range from 0.8 to 1.4 g/cm3.Type: ApplicationFiled: July 23, 2003Publication date: June 10, 2004Inventors: Hiroyasu Abe, Masayuki Kato

Patent number: 6667429Abstract: Wood such as spruce, maple, and hornbeam are retained in high pressure steam of pressure 0.2 to 1.6 MPa at 120 to 200° C. for 1 to 60 minutes, and subsequently, cooled and dried to obtain a modified wood having superior acoustic properties and old wood-like appearance due to a change to a deep color tone. Since the conventional modification methods by chemical treatment using chemicals such as resorcin and formaldehyde are not used, the treatment steps are simple and a modified wood used as a material for musical instruments is obtained at low cost.Type: GrantFiled: August 29, 2002Date of Patent: December 23, 2003Assignee: Yamaha CorporationInventors: Hiroyasu Abe, Junji Fujii
