Abstract: A power tool includes a hook portion having a hook holding portion, which is provided in a housing and has engaging teeth provided in the housing. A hook having a shaft portion is inserted into the hook holding portion and provided with fitting teeth meshing with the engaging teeth An elastic body is adapted to push the hook against a handle portion at all times, and a slip-off preventing part holding portion is adapted to move the hook in a direction of an axis thereof against a force of the elastic body and to cancel the mesh between the teeth to thereby enable the hook to turn.

Abstract: A cover which covers outer peripheries of fastening screws are disposed on an outer periphery of a hammer case. A stopper which detachably positions and fixes the cover to the outer periphery of the hammer case is disposed.

Abstract: A royal jelly peptide which has a function as a queen bee's attraction cofactor and can enhance the biological defense system of an animal (an immunopotentiating effect); and a composition containing the same.

Abstract: An electric driver includes a hook portion which is constituted by a hook-like portion and a connecting portion for connecting the hook-like portion to the handle. The hook-like portion is constituted by a base portion connected to the connecting portion and a bent portion continuous to the base portion and a front end portion continuous to the bent portion and arranged at a position substantially opposed to the base portion and can be deformed. The front end portion and the base portion can be proximate to and remote from each other. The connecting portion holds the hook-like portion in a state of being hung down in a direction substantially the same as a direction of extending the handle. The hook-like portion is held centering on a first rotating axis center extended in the direction of hanging down the hook-like portion pivotably relative to the handle.

Abstract: An epitaxial silicon wafer is provided in which an epitaxial layer is grown on a silicon wafer having a plane inclined from a {110} plane of a silicon single crystal as a main surface. In the silicon wafer for growing the epitaxial layer thereon, an inclination angle azimuth of the {110} plane is in the range of 0 to 45 degrees as measured from a <100> orientation parallel to the {110} plane toward a <110> direction. With such an arrangement, LPDs of 100 nm or less can be measured from a {110} wafer that has a carrier mobility (including the hole and electron mobilities) higher than that of a {100} wafer. Also, surface roughness degradation in the {110} wafer can be suppressed. Also, the surface state of the {110} wafer can be measured. Further, a quality evaluation can be performed on the {110} wafer.

Abstract: A method of producing an epitaxial wafer, comprising: performing epitaxial growth of silicon on a main surface of a wafer made of a silicon single crystal; performing surface flattening pretreatment of a main surface of the wafer using a treatment liquid of a predetermined composition at a temperature of 100° C. or less, thereby forming an oxide film of a predetermined thickness while removing particles adhered on the main surface of the wafer; and performing a surface polishing step where the main surface of the wafer is mirror polished.

Abstract: To improve image quality upon preventing abrasion traces from strongly forming on a surface of a fusing member, an invented fusing device has a pressure member, a fusing member movably arranged as faced with the pressure member, and a contact element arranged in contact with an outer circumferential surface of the fusing member, with the surface roughness of the fusing member of 1.0 to 4.0 [?m]. When the fusing member is moved in contact with the contact element, the contact element rubs a surface of the fusing member, but in the fusing member, the portion in contact with the contact element and the portion not in contact with the contact element become about equal in the surface roughness with the above surface roughness.

Abstract: A fixing apparatus transports a recording medium carrying a developer image on it and heats the developer image to fix into the recording medium. A heat roller extends in a direction of its rotational axis and generates heat. An endless belt is loosely entrained on a belt guide. A pressurizing mechanism engages the endless belt from inside and urges the endless belt against the first rotating body. When the rotating body rotates, the endless belt and the second rotating body are driven in rotation in such a way that the recording medium is pulled in between the first rotating body and the endless belt.

Abstract: A subject for the invention is to provide an electromagnetic-shielding light-diffusing sheet which has satisfactory electromagnetic shielding performance, attains a large transmitted-light amount, and can emit even diffused light having reduced unevenness of luminance. The invention relates to an electromagnetic-shielding light-diffusing sheet comprising a light-diffusing sheet main body and, laminated on at least one side thereof, a light-transmitting electroconductive layer having a surface resistivity of 105 ?/? or lower.
