Abstract: According to an embodiment of the invention, there is provided an information processing apparatus including: an emission unit configured to emit a notification sound upon predetermined operation; a storage unit configured to store a call destination list including a plurality of call destinations; a determination unit configured to determine a call destination based on a preset priority from the plurality of call destinations if the predetermined operation is performed; and a call origination unit configured to originate a call to the determined call destination.

Abstract: A method enabling to form a lubricating layer on a work piece and a device to form the same in a simple blast processing are provided, in which injection materials can be injected at higher speed than the conventional way, thereby even a small specific gravity injection materials such as graphite and the like can be used for blast operation. In an injection nozzle of a direct pressure type blast processing device which injects a mixture of injection materials and compressed gas, an aperture which is formed in an axial direction of the injection nozzle has such shape that meets the following conditional equations (1) and (2) in a cross section orthogonal to the axial direction at an arbitrary distance x away from the entrance of the injection nozzle.
