Title: Power feed method for electric driver
Inventor: MIYAZAKI TADANOBU
IPC: B23P19/06
Filed: 1991-08-30
Abstract: PURPOSE:To decide fastening torque exactly by increasing electric current fed to a motor in response to a screwing torque increase when screwing is performed, stopping electric power feed when current value required for screw head seating is attained and repeating the same current feed and stop again after the motor has stopped. CONSTITUTION:The screw 50 of a rocking piece 54 is attracted to the lower end of a pit 34, and the rocking piece 54 is retreated in the direction of an arrow mark. After that the screw 50 is screwed in a material 52 to be screwed by rotation of a motor 24. The electric feed to the motor 24 is started from a current value I1 for obtaining a required rotational speed under no load condition, and a current value 1 is increased together with increase of screwing torque T. The electric feed is stopped when the current value reaches a current value I2 corresponding to seating torque. The electric feed stop is continued for time t for stopping the motor 24 completely. When the motor 24 stops, the electric feed and stop are repeated by the same process again, and the process is repeated until the screw is completely seated.

IPC: G01N21/67
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To increase analysis accuracy near a boundary to the foundation of a thin-film sample. SOLUTION: A light emission part 1 is equipped with a first electrode 11 and a second electrode that has a smaller diameter than the first electrode 11 and can advance toward and retreat from positions B and F. Voltage is applied between the electrode and a sample 2 by a power supply 4 for generating glow discharge 8, and generated light 9 is introduced to a spectral part 21 for spectral detection, and the qualitative/quantitative analysis of an element being contained in the sample 2 is made. Although, in the sample 2, a thin film is coated on foundation 2B, a second electrode 12 is allowed to retreat to the position B while a thin film 2A is analyzed, and the voltage is applied to the first electrode 11 for discharging for analysis. When the entire thin film 2A is sputtered for exposing the foundation 2B, the second electrode 12 is advanced to a position F for changing a switch 3, and the voltage is applied to the second electrode 12 for discharging, thus reducing a discharge range on a sample surface on the analysis of the foundation 2B, and hence eliminating the influence of an element being evaporated from the side surface of a crater.

Abstract: PROBLEM TO BE SOLVED: To constitute common components, to improve remarkable productivity by simplifying wirings and to reduce its cost by constituting to transmit data detected by a detecting means to a main controller through a signal line by a transmitting/receiving means in a terminal side control means of a sensor. SOLUTION: In receiving a designation of starting a detecting operation from a main controller 16 by a transmitting/receiving means, a terminal control means 22 executes the detecting operation by detecting means 19, 20.
