  • Publication number: 20150220447
    Abstract: An information processing apparatus includes a free page storage unit and a page allocating unit. The free page storage unit divides a memory region in a memory into pages of a plurality of different page sizes and manages the divided pages, and stores management information about an initialization state corresponding to an unused memory region in the memory. The page allocating unit selects a free page of a page size according to a requested region size or a requested page size from the free page storage unit when an allocation of the unused memory region is requested, and performs an initializing process on a memory region on which the initializing process has not been performed in a memory region corresponding to the free page using management information about the selected free page.

  • Publication number: 20150190910
    Abstract: Provided is a motor-driven screwdriver configured such that the upper limit value of transmittable rotational driving force differs between forward and backward rotation. The motor-driven screwdriver has a bit holder and a rotational driving force transmission device for transmitting rotational driving force to the bit holder. The rotational driving force transmission device has a driving member, a driven member having through-holes, power transmission members held in the through-holes, respectively, and an urging member urging the power transmission members inward. Each through-hole is provided such that a through-hole center axis passing through a center between a forward rotation guide surface and backward rotation guide surface of the through-hole does not intersect a rotation center axis, whereby the force with which the power transmission member is pushed radially outward is made to differ between forward and backward rotation.

  • Publication number: 20140215483
    Abstract: A memory allocation/free replacing unit hooks a call of a memory allocating/freeing unit. The memory allocation/free replacing unit generates information required for totalization of a dynamically used memory amount, writes the generated information to a log file, and calls the memory allocating/freeing unit to perform memory allocation and free. A totalization processing unit loads the log file and totalizes a dynamically used memory amount for each dynamic library, for each function, or for each thread.
