A gas generator, includes: a housing having closure shell, a diffuser shell including a gas discharge ports, and a flange portion; an inner tube member defining a combustion chamber in an outside thereof for accommodating a gas generating agent, the igniter being attached to the closure shell such that the igniter projects inside from a hole formed in the bottom plate of the closure shell, the annular porous member having a plurality of holes which are smaller than the size of the gas generator, defining a space above the combustion chamber, a total opening area (A1) of the gas discharge ports being smaller than a total opening area (A2) of a gas pathway extending from the combustion chamber to the gas discharge ports (A1
摘要:
In an information processing apparatus, a control unit includes a first clock device for providing the time of day. A physical domain includes a second clock device, and implements a logical domain that functions as a virtual information processing apparatus. The control unit controls a first time-of-day difference between the time of day of the first clock device and that of the second clock device. The physical domain controls a second time-of-day difference between the time of day of the second clock device and that of the logical domain. In the information processing apparatus, the time of day on the logical domain is controlled based on the first and second time-of-day differences.
摘要:
A lubricant oil supplying apparatus (1-1) provided for a power transmission apparatus (1) having an accumulating part (9), a rotating member (7) rotating interlockingly with rotation of a drive wheel to feed a lubricant oil in the accumulating part, and an oil receiving part (8) disposed above in the vertical direction than the rotating member, and supplying the lubricant oil to the oil receiving part, in which a passage member (10) for guiding the lubricant oil fed by the rotating member to the oil receiving part is provided. The passage member has: a first component part (11) provided so as to be opposed to the rotating member along a circumferential direction and forming, between the rotating member and itself, a first passage (13) to which the lubricating oil flows; and a second component part (12) forming a second passage (14) for guiding the lubricant oil in the first passage to the oil receiving part, and the second passage is connected to the first passage on the upstream side in the flow direction of an outflow port (13b). The lubricant oil supplying apparatus further includes a suppression structure (7, 10) of suppressing flow of the lubricant oil in the first passage from a connection part (13c) to the second passage toward the outflow port.
摘要:
A display method is performed by a display panel having a display area where a plurality of pixels are arranged in a matrix so as to correspond to intersections of a plurality of scanning lines and a plurality of data lines. The display method includes: driving light emitting elements of the pixels on the basis of image data; switching a plurality of different images to display the images on the display area such that portions of the images overlap each other; and putting a black display portion in a portion of the image after the switching which overlaps the image before the switching.

A base station includes at least one first application section, a determining section, and a controlling section. Each of the first application sections executes one of a plurality of first application programs corresponding to one of a plurality of first application services utilizing a first wireless communication service provided by a mobile virtual network operator. The determining section receives a connection request to connect to the first application service from a first terminal for using the first wireless communication service, and determines the first application section corresponding to the first application service specified in the connection request. The controlling section controls communications between the determined first application section and a server managed by the mobile virtual network operator and between the determined first application section and the first terminal.

A data-line drive circuit controls a current value of a control signal in every cycle T1 based on upper 8-bit digital data DAB of digital data In, and performs pulse-width control in a cycle T2 based on lower 2-bit digital data SUB of the digital data In for the portion which is D/A-converted based on the same digital data of the control signal. It is thus possible to provide an electronic circuit suitable to inhibit a variation in the luminance so as to control the luminance levels of pixels with high precision.
摘要:
A display device includes the following elements. A display has a display area and includes an electro-optic layer and a light-reflecting layer reflecting light emitted from the electro-optic layer to the viewing side of the display device, the light-reflecting layer being arranged in the display area. A plate-shaped exterior has a frame area including a portion located outside the periphery of the display. An antireflective plate continuously covers both of the display area and the frame area. The antireflective plate prevents external light, which enters the viewing side of the display device and is reflected by the light-reflecting layer or the frame area, from emerging on the viewing side.
