A coil-type electronic component has a coil inside or on an outer surface of its base material and is characterized in that: the base material is constituted by a group of grains of a soft magnetic alloy containing iron, silicon and other element that oxidizes more easily than iron; the surface of each soft magnetic alloy grain has an oxide layer formed on its surface as a result of oxidization of the grain; the oxide layer contains the other element that oxidizes more easily than iron by a quantity larger than that in the soft magnetic alloy grain; and grains are bonded with one another via the oxide layer.

摘要:
An electrodeposited wire tool has a core wire extending in a longitudinal direction, a plating layer provided on an outer peripheral surface of the core wire, superabrasive grains held by the plating layer and coating layers covering the outer peripheral surfaces of the superabrasive grains. The coating layers are constituted of electroless Ni—P platings. The coating layers are heat-treated, and the electroless Ni—P platings are partially or entirely crystallized.

An electrophotographic photosensitive member is provide which inhibits recovered toner from leaking out of the edge portion at the time of long-term use, and has good durability. Each of at least both edge portions of the surface layer of the electrophotographic photosensitive member has a region in which independent depressed portions are formed at a density of ten or more portions per 100 μm square. An average depth Rdv-A, an average short axis diameter Lpc-A, and an average long axis diameter Rpc-A, of the depressed portions are respectively in specific ranges. When an angle formed between the circumferential direction of the electrophotographic photosensitive member and the long axis of each of the depressed portions is represented by θ, the depressed portions are formed so that the angle θ satisfies the relationship of 90°

An outer body of ball shell type has an opening. A camera is located in the outer body and receives an image from outside of the outer body through the opening. A camera support unit is located in the outer body and rotationally supports the camera along a first axis and a second axis mutually crossed at a center of the outer body. A first camera actuator is located in the outer body and rotationally actuates the camera around the first axis. A second camera actuator is located in the outer body and rotationally actuates the camera around the second axis.
