摘要:
A construction of boiling water reactor core having a plurality of fuel assemblies. Some of fuel assemblies have an infinite multiplication factor which is larger at their upper regions than at their lower portions, so that the effective multiplication factor of the reactor core is larger at the upper portion than at the lower portion of the reactor core under an equal condition. Consequently, a relatively flat axial power distribution is established even under an uneven axial void distribution.
摘要:
A fuel assembly suitable for use in boiling water reactor. The fuel assembly has a specific pattern of distribution of enrichment, so that the upper region of the assembly has a larger infinite multiplication factor than that of the lower region. In an example, the distribution of enrichment is such that the upper region has a mean enrichment larger than that of the lower region, while, in another example, the mean enrichment is maintained constant over the length of the assembly but the difference of enrichments between the central and peripheral portions of a plane normal to the axis of the assembly is made smaller at the upper region than at the lower region.
摘要:
A process comprising extracting the blood of horseshoe crabs (Limulina) into an isotonic buffer solution containing an agent which inhibits the agglutination of amebocyte, separating the amebocyte from said solution, breaking the amebocyte, and recovering Limulina lysate, which is characterized in that methyl derivatives of xanthine such as theophyline, theobromine, or caffeine, or their salts, are used as the amebocyte's agglutination-inhibiting agent is disclosed.
摘要:
To appropriately prevent a burn-in phenomenon when a still image such as an OSD screen is displayed on a display panel. When a menu screen is displayed on a video screen in a superimposed manner, a menu phrase in at least one of a left-eye video and a right-eye video is deleted on a menu background area. A time period in which a brightness difference between still pixels in a boundary between a menu background area and a menu phrase remains large is reduced, and thus the occurrence of the burn-in phenomenon can be prevented. However, the menu background area is constantly displayed without being deleted, so that screen flickering does not occur.

The purpose of the present invention is to provide: an anti-vibration rubber composition which enables the production of a hardened rubber article having excellent heat resistance, compression set, low dynamic magnification, tensile properties (elongation, strength), low-temperature properties and workability (scorch resistance); and an anti-vibration rubber which is produced by hardening the rubber composition. The anti-vibration rubber composition is characterized by comprising a rubber component mainly composed of a diene rubber, a bismaleimide compound as a vulcanizing agent, and N-phenyl-N-(trichloromethylthio)benzenesulfoneamide.
摘要:
A PWM module is provided to output a driving pulse to a switching device in synchronization with a synchronizing pulse having a frequency twice the frequency of the high-frequency current of a primary-side induction line. The PWM module performs output voltage feedback control such that the output voltage of an output capacitor is set at a reference voltage. The module outputs, to the switching device, the driving pulse having a half width of the pulse width of a driving pulse that can be outputted, at the start of power supply to the primary-side induction line. Moreover, the module forcibly performs the output voltage feedback control if an output voltage of the output capacitor does not increase to the reference voltage within a reference time.
摘要:
The user of a mobile station which is prepared to receive information providing services from unspecified IP (Information Providers) accesses a gateway server and performs a pre-registration procedure (S71). When an IP server has information to provide to users, it constructs the information in the form of electronic mail, appends user attribute data, and sends this to the gateway server (S72). Upon receiving electronic mail with attribute data, the gateway server stores the electronic mail in a third mailbox, makes a comparison of the user attributes, and calls the mobile stations of relevant users (S73). A user who has received a call requests a download of the electronic mail from the gateway server (S74). The gateway server sends electronic mail to the mobile station which made the request (S75, S76).

摘要:
Management server 16 may obtain application programs from content server 20 in response to requests of mobile terminal 11. Management server 16 may transmit the obtained application programs to mobile terminal 11 with information concerning reliabilities of the application programs. After mobile terminal 11 receives the application programs from management server 16, mobile terminal 11 manages operations of the application programs. Operations of the application programs are coordinated with operations of other programs using the information concerning the reliabilities corresponding to the application programs. Management of the coordinated operations of the application programs avoids problems concerning information security, where valuable information may be distributed unexpectedly because of operations of low reliable application programs. As a result, convenience of users of mobile terminals 11 can be improved without deteriorating the information security of mobile terminals 11.
