摘要： A heat roll for electrophotography of a surface heating type having a heating resistor is arranged such that a bonding layer, an insulating layer, a resistance layer, and a surface insulating layer are consecutively provided on an outer surface of a hollow cylindrical core, and a bearing member for fitting with a bearing is fitted at each opposite end of the heat roll. A pipe or a round bar formed of aluminum, an aluminum alloy, copper, a copper alloy, or the like which has a greater coefficient of thermal conductivity than that of mild steel is disposed inside the core to permit a uniform distribution of the temperature. In addition, a gap of 0.2 mm or more is provided between the inner surface of the core and an outer peripheral surface of the member formed of the high-temperature conductive material. As a result, effects that are attributable to a difference in the coefficients of thermal conductivity can be alleviated, and a temperature rise of the heat roll up to a predetermined temperature can be accelerated.

摘要： A hand-held powered screw tightening tool has a detecting device to detect a rotation angle of a rotary member in a clockwise direction and a counterclockwise direction. In screw tightening, an angle obtained by subtracting a cumulative total of the rotation angle of the rotary member with rebound, if any, in a counterclockwise direction from a cumulative total of the rotation angle of the rotary member in the clockwise direction is detected and accumulated as a total rotation angle (P) and a rotation angle formed during the deceleration at the hammering is detected as &Dgr;H and accumulated, and a preset design angle Pd for hammering is accumulated. A wobbling angle is calculated from Equation: A wobbling angle=P−a cumulative total of Pd−a cumulative total of &Dgr;H (where Pd is a design value of the impact wrench, indicating an angle corresponding to 360°/m for the case of the m number of hammerings per rotation of the rotary member). When the cumulative total of the rotation angle &Dgr;H reaches the predetermined design angle for screw tightening, the rotation of the rotary member is stopped. In screw loosening, the rotary member is rotated in the opposite direction, so that when the rotation angle of the rotary member reaches a predetermined number of rotations in the loosening direction similarly, the rotation of the rotary member is stopped.

摘要： Conventionally, as screw tightening axial force control, there is a control method such as a torque control method. The torque control method requires estimation of a torque coefficient, and has a problem that a calculated axial force value is an estimated value. An object of the present invention is to provide a method for directly controlling an axial force by calculating the axial force generated by an impact force by using an impact wrench. A 45-degree slant line is set from an origin O of orthogonal coordinate axes to be used for screw tightening axial force control, an impact progress point Hi generated by an i-th impact is detected on the 45-degree slant line, a length HSi of a line segment OHi is read, and an axial force value Fi after the i-th impact occurs is calculated by using the formula Fi=HSi×cos 45°. Another method for controlling the axial force by using impact information is also disclosed.

摘要： A die casting method and a casting that is obtained through use of the die casting method. The die casting method can solve problems such as air catching occurring at the time of injection into the cavity of a die and molten metal run defect, thereby enabling efficient production of defect-free perfect castings. Via a mouth piece 7 and a molten-metal feed port 4, molten metal from a molten metal feeder flows into a casting sleeve 2 while undergoing laminar flow. When the molten metal reaches a predetermined level, a plunger tip 5 is moved upward within the casting sleeve 2 and stops at a position where the side surface of the plunger tip 5 closes the molten-metal feed port 4. The molten metal that has flowed into the casting sleeve 2 is cooled by a cooling medium flowing through passages 2b formed within the casting sleeve 2 so that said molten metal forms primary crystals. Simultaneously, through use of a high frequency coil 6, the molten metal is subjected to electromagnetic agitation. As a result, the molten metal is fluidized and soaked. At this time, the temperature of the molten metal is detected by a sensor. When it is judged that the solid phase ratio has reached an arbitrary value in the range of 10-60%, the plunger tip 5 is moved upward in order to inject the semi-solidified molten metal into the cavity of a die 1.
