The polishing composition provided by the present invention contains water, oxidant A selected from compounds other than peroxide, a first metal salt selected from alkaline-earth metal salts, and a second metal salt selected from salts each of which has a cation of a metal belonging to groups 3 to 16 in the periodic table, and an anion.

Abstract: Provided are a polishing method and a polishing composition that are applied to polishing of silicon carbide and allows reduction of rise in pH of the polishing composition and increase in pad temperature during polishing. Provided is a method of polishing an object to be polished having a surface formed of silicon carbide. The method includes steps of preparing a polishing composition, and supplying the polishing composition to the object to be polished and polishing the object to be polished. The polishing composition contains permanganate, a metal salt A, and water. The metal salt A is a salt of a metal cation having a pKa of less than 7.0 in form of a hydrated metal ion, and an anion.

Abstract: An information processing apparatus includes a processor that executes an operating system, a nonvolatile main memory device to which the processor is directly accessible and that has a controller, and an external storage device to which the processor is not directly accessible. When the processor detects an error of the operating system, the processor resets devices other than the nonvolatile main memory device and restarts the operating system, and the controller writes data of the nonvolatile main memory device to the external storage device.

Abstract: When plural virtual servers are distributed to plural physical servers, efficient distribution is performed in terms of the processing capacity of the physical servers and their power consumption. Firstly a second load of each virtual server in future is predicted based on a first load in a prescribed time period up to the present of each of the plural virtual servers. Next, the schedule is determined to distribute the plural virtual servers to the plural physical servers based on the second load of each virtual server so that a total of the second loads of one or a plurality of the virtual servers distributed to a physical server is within a prescribed range of proportion with respect to processing capacity of the physical server. Furthermore, the distribution is instructed (execution of redistribution) in accordance with the schedule.

The interior of the vacuum cleaner main body and the grip portion are connected in a freely attachable and detachable manner. It is possible to perform both ordinary use (floor cleaning) using a suction tool main body and use of an attachment through a grip portion by utilizing one successive flow path so that it will not be necessary to provide a flow path switching mechanism to thereby simply the arrangement.

Abstract: The acceleration applied to a selected device such as a magnetic disc drive system can be detected by the use of an acceleration detector having at least one piezoelectric acceleration sensor unit. The sensor unit includes a piezoelectric element, a supporting member for the piezoelectric element and two electrical leads. The piezoelectric element is formed with a pair of elongate sheets made of a piezoelectric ceramic and an intermediate insulation layer interposed between the elongate sheets to generate a voltage difference instantaneously therebetween in response to the acceleration of the acceleration detector. The support member is made of an electrically insulating resin, and has a concave which is formed with side and bottom walls and a top opening. The side wall is provided with a slit in which the piezoelectric element is tightly caught in such a manner as to divide the concave into two open-chambers and be supported by the support member in a cantilever fashion.
