  • Publication number: 20140086388
    Abstract: 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.

  • Publication number: 20130306878
    Abstract: An electrode to be used for an electrostatic lens, wherein the electrode at least includes: a first substrate having a first through-hole and a second substrate having a second through-hole; the first substrate having a thickness smaller than the second substrate; the first through-hole having a diameter smaller than the second through-hole; the second substrate having a specific resistance smaller than the first substrate, wherein the first substrate and the second substrate are superimposed so that the first through-hole and the second through-hole are aligned relative to each other. Notching taking place near any of the through-holes in a dry etching process can be reduced, and thus, the through-holes can be formed accurately.

  • Patent number: 8428825
    Abstract: 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.

  • Patent number: 8286999
    Abstract: An occupant protection device includes a plurality of gas generators that actuate respective mechanisms, and a control portion that actuates the gas generators. If a condition for actuating at least one of the gas generators is fulfilled and a condition for actuating the other gas generators are unfulfilled, the other gas generators are controlled by the control portion at a timing that is uninfluential on an actuation state of one of the mechanism actuated by the one of the gas generators and that is different from a preset timing for actuating the other mechanisms actuated by the other gas generators.

  • Publication number: 20120064228
    Abstract: 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.

  • Patent number: 7930480
    Abstract: 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.
