Patent number: 11351694Abstract: [Problem] To address the problem of conventional old wood texture or antique taste boards which lack natural looking worn effects and present an appearance of an artificial treatment applied thereto. [Solution] Unlike a conventional configuration in which the rotary shaft of a roll brush is simply and fixedly arranged parallel to the wood grains of a board to which surface treatment is applied or the painted surface where paint is applied to the wood grains, the rotary shaft may be obliquely set to any angle including a right angle, and may be rotationally driven at high speed at a given inclined angle relative to the horizontal surface of the board along a left to right direction of the roll brush.Type: GrantFiled: April 15, 2019Date of Patent: June 7, 2022Inventor: Yoshitaka Nakano

Patent number: 7211839Abstract: A semiconductor device is formed by a first layer 32 composed of AlGaN, a second layer 42 composed of GaN, a gate electrode 34, a source electrode 38, and a drain electrode 28. The first layer 32 has a region 32a formed between the gate electrode 34 and the second layer 42. A channel is formed in the vicinity of the boundary 24 of the first layer 32 and the second layer 42. The second layer 42 has p-type conductivity and is in contact with the source electrode 38. When electrons flow in the channel, the electrons collide with surrounding atoms, and holes are formed. If holes are accumulated inside the semiconductor device, the presence of the accumulated holes causes dielectric breakdown. In the semiconductor device of the invention, holes are discharged to the outside of the device thorough the second layer 42 and the source electrode 38, and accumulation of holes can be prevented.Type: GrantFiled: February 5, 2004Date of Patent: May 1, 2007Assignee: Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Tetsu Kachi, Yoshitaka Nakano, Tsutomu Uesugi
