  • Publication number: 20090308624
    Abstract: 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.

  • Patent number: 7527692
    Abstract: Above a substrate holder 1, an ordinary fluid jet nozzle 2 which is capable of injecting drops of a solution having ordinary particle diameters, a fine fluid jet nozzle 3 which is capable of injecting drops of a solution having fine particle diameters which are smaller than the ordinary particle diameters, and a regular reflection laser displacement gauge 4 are disposed. These are attached on the same plate, thereby forming a head 10. The head 10 freely moves in directions X, Y and Z, as an X-axis drive portion 41, Y-axis drive portions 42 and 43 and a Z-axis drive portion 44 operate in accordance with operation commands received from a controller 50 which controls the apparatus as a whole. It is therefore possible to set the head 10 to a predetermined position on a substrate S which is held by the substrate holder 1. Thus, the respective nozzles supply the solutions to any desired positions the substrate S.

  • Patent number: 6812414
    Abstract: A strain plate (4) is placed on a base plate member (3) without using any fixing means. The strain plate (4) is formed with a straight groove (7) for restricting its strain direction to one direction. The base plate member (3) is fitted with position regulating members (14) opposite the four corner portions of the strain plate (4), individually. Each position regulating member (14) is formed with a slit such that a part of it can be elastically deformed with ease. The position regulating blocks can absorb the displacement of the sides of the strain plate that is caused when the strain plate (4) is deformed as a weighing machine (1) is loaded.
