  • Patent number: 7664921
    Abstract: A method for accessing shared memory cards from each of plural processor cards is disclosed. The shared memory cards are composed of a shared memory card of an operating system and a shared memory card of a standby system in a redundant configuration, and each of plural processor cards individually access the shared memory cards. Each of the plural processor cards is connected to the shared memory card of the operating system and the shared memory card of the standby system in a point-to-point structure via corresponding serial buses and executes data transmission on a one to one basis to/from the shared memory card of the operating system and the shared memory card of the standby system.

  • Patent number: 7449978
    Abstract: In a fitting region for a SAW filter which includes langasite as its piezoelectric element, there are included an input side terminal electrode and an output side terminal electrode which are connected to an input terminal and to an output terminal of the SAW filter. To each of the terminal electrodes, at a position which is separated by just a predetermined distance from the fitting region of the SAW filter, there is connected a micro strip line which extends in mutually opposite directions along a direction which is parallel to the transmission direction of a frequency signal within the SAW filter. A slit is provided in the fitting region of the SAW filter and extends in a direction which intersects the transmission direction of the frequency signal within the SAW filter. A plurality of through holes are provided in the printed substrate and electrically connect together its surface and its rear surface which is grounded.

  • Patent number: 7331742
    Abstract: A hollow portion of a spindle through which a draw bar and a disc spring assembly are inserted has a closed chamber structure and constitutes an oil pool chamber in which a lubricating oil is filled. The bearing portions that support the draw bar in the oil pool on both sides have the same inner diameter so that the volume of the oil pool chamber does not change when the draw bar is moved forward and backward. As a result, the lubricating oil is not pushed out of the oil pool chamber. Thus, a spindle unit can be provided in which a clamping device including the draw bar and the disc spring assembly for clamping a tool or a workpiece pallet at the forward end of the spindle can be reliably lubricated, so that the friction on and the breakage of the clamping device is reduced and that the service life of the unit is lengthened.

  • Publication number: 20080040552
    Abstract: The occurrence of a failure in any of an operational processor and a standby processor is monitored, and when a failure occurs in the operational processor, switching to the standby processor is made. A cache memory of each processor has a plurality of ports through which data can be read and written simultaneously. A cache memory controller of the operational processor transfers an update for the cache memory to the cache memory of the standby processor by using a port different from the port used for updating. A cache memory controller of the standby processor writes the received update into the cache memory by using a port different from the port used for updating.

  • Publication number: 20070098511
    Abstract: A hollow portion (7) of a spindle 5 through which a draw bar (9) and a disc spring assembly (11) are inserted has a closed chamber structure and constitutes an oil pool chamber in which a lubricating oil is filled. The bearing portions (21, 39) for supporting the draw bar (9) in the oil pool on both sides thereof have the same inner diameter so that the volume of the oil pool chamber does not change when the draw bar (9) is moved forward and backward. As a result, the lubricating oil is not pushed out of the oil pool chamber. Thus, a spindle unit can be provided in which a clamping means, consisting of the draw bar (9) and the disc spring assembly (11), for clamping a tool or a workpiece pallet at the forward end of the spindle can be reliably lubricated, so that the friction on and the breakage of the clamping means is reduced and that the service life of the unit is lengthened.

  • Publication number: 20060212754
    Abstract: In a multiprocessor system in which a plurality of processors are managed by a management processor, and an access to a shared memory is controlled by a bus control device, the management processor or the bus control device provides to the processors time information synchronized at a time of a system start-up, and each of the processors collects its own running history information associated with the time information. Also, when detecting a fault, each of the processors stops a collection of its own running history information, and stops a collection of running history information of other processors by notifying the fault detection to the other processors. Each of the processors, after having stopped the collection of its own running history information, stores the running history information in a nonvolatile memory provided other than the shared memory.

  • Patent number: 4608001
    Abstract: In a scroll type fluid machine wherein there are engaged stator scroll means and rotary scroll means in intermeshing relationship with each other, each having a spiral or scroll blade portion projecting in the axial direction from the lateral plate surface in such a manner that the rotary scroll means may move in solar revolving motion with respect to the stator scroll means mounted stationary on a cup-like member by the rotating motion of a main shaft, while restricting the rotating motion of the rotary scroll means by function of a rotation blocking mechanism, so that the fluid may operatively be sucked into and delivered out of the fluid machine with a differential pressure produced therein in continued variation, an improvement is accomplished in that an angular phase relationship between the rotary scroll means and the stator scroll means may be compensated properly by shifting in rotation the rotary scroll means in the direction of rotating motion thereof in accordance with the extent of initial wear ge
