Publication number: 20140086388Abstract: A radiation generating unit of the present invention includes an electron beam source that emits an electron beam and can change the size of a region to be irradiated with the electron beam on a target while maintaining constant the center position of the region to be irradiated with the electron beam. Furthermore, a target is adopted where the number of types of target layers included in the region to be irradiated with the electron beam can be changed by changing the size of the region to be irradiated with the electron beam. The radiation quality can be switched without changing the radiation focus, and the radiation quality of a high energy radiation can be largely changed.Type: ApplicationFiled: September 10, 2013Publication date: March 27, 2014Applicant: CANON KABUSHIKI KAISHAInventors: Shuji Yamada, Takeo Tsukamoto, Tadayuki Yoshitake, Kazushi Nomura

Patent number: 8428825Abstract: In the case of a severe collision, the severity of the collision exceeds a first threshold value at which a pretensioner mechanism starts to activate, and then exceeds a second threshold value within a collision-discriminating time range T following the start of the activation; therefore, the force limiter mechanism unit is set at a high load. In the case of a gentle collision, the severity of the collision exceeds the first threshold value, at which the pretensioner mechanism starts to activate, but does not exceed the second threshold value within the collision-discriminating time range T following the start of the activation; therefore the force limiter mechanism unit is set at a low load. Therefore, without a determination delay, the switching of the force limiter mechanism can be appropriately selected.Type: GrantFiled: February 13, 2009Date of Patent: April 23, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shuji Yamada, Kazunori Nogi, Yujiro Miyata, Shinji Ito

Publication number: 20120064228Abstract: A light extracting structure which can efficiently extract light emitted from a light-emitting layer. A capture layer is formed onto a first translucent material film formed on a substrate. A dispersion liquid obtained by dispersing particles into a dispersion medium is coated onto the capture layer. The dispersion medium is volatilized. A particle sediment layer is formed onto the capture layer. The particles in the lowest layer of the sediment layer are captured into the capture layer at a filling rate of 93% or more for the 2-dimensional closest packing. The non-captured particles are removed. An etching is performed by using the captured particles as a mask. Concave portions are formed in the first translucent material film. The particles remaining after the etching and the capture layer are removed. Thereafter, the concave portions are embedded with a second translucent material having a different refractive index.Type: ApplicationFiled: August 24, 2011Publication date: March 15, 2012Applicant: CANON KABUSHIKI KAISHAInventors: Shin Kitamura, Kazuhiko Araki, Shuji Yamada, Osamu Takamatsu

Patent number: 7930480Abstract: Embodiments of the invention improve the performance of a HDD (Hard Disk Drive). In one embodiment, MBR (Master Boot Record) is read from a magnetic disk. The read MBR is stored in a sector buffer by an event handler. A segment control section acquires the MBR stored in the sector buffer and refers to the partition type field to identify the file system. The segment control section refers to a cache mode table and selects a cache mode which is associated with the file system specified in the MBR. In the subsequent read and write operations, buffer handling and command execution control are performed according to the determined cache mode. Since an appropriate cache mode is selected depending on the file system, it is possible to raise the performance.Type: GrantFiled: March 21, 2005Date of Patent: April 19, 2011Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventor: Shuji Yamada
