Title: Method and device for controlling position of servomotor
Inventor: ARAKAWA YUICHI
IPC: B25J19/06
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To conduct high-speed, high-precision collision detection irrelevantly to the rotating speed of the servomotor by deciding a collision based on an estimated disturbance power value being the product of an estimated disturbance torque value and the rotating speed of the motor when a collision of a movable part is detected from estimated disturbance. SOLUTION: A disturbance torque observer 20 inputs a torque current command Ic outputted from a speed control part 13 and the rotating speed Vf of the motor 15 and outputs the estimated disturbance torque value TL. A multiplier 30 multiplies the estimated disturbance torque value TL by the rotating speed of the motor 15 and outputs estimated disturbance power PL to a decision part 31. The decision part 31 compares the estimated disturbance power PL with permissible disturbance power determined in consideration of the mechanical strength, etc., of the movable part 16, and judges that there is a collision when the estimated disturbance power PL is larger than the permissible disturbance power and outputs an alarm signal AL to a numerical control part 11 and a speed control part 13. The speed control part 13 stops the motor 15.

Abstract: PURPOSE: To effectively remove offensively odorous components from air by a simplified method in which an ozone-oxidating-washing tower is organically combined with an adsorption tower packed with a solid filler, e.g., lithium bromide, activated carbon, etc.  
     CONSTITUTION: An ozone-containing gas is dispersed in fine bubbles into the washing water 4 through the diffuser pipe 13 and then directed upwards in the washing water 4 from the bottom of the washing tower 1, during which various offensively odorous components absorbed in the washing water 4 are decomposed by oxidation and most of excessive ozone is physically dissolved in the washing water 4.

Filed: 1985-05-30
Abstract: PURPOSE:To increase reading chances and to prevent reading defects with a bar code reader by resetting a magazine to its original position for the second reading action in case a reading defect occurs. CONSTITUTION:A bar code reader 4 reads a bar code label 3-1 of a magazine 2-1 and a deciding circuit 6 decides the priority of the reading result.

Filed: 1988-05-16
Abstract: PURPOSE:To operate a power supply circuit normally in the standby state without incurring increase in the number of components or cost-up by using a resistor used as a horizontal drive resistor of a horizontal system deflection circuit at set-on as a dummy load in the standby. CONSTITUTION:A standby signal control TR 14 is turned off by a standby signal 9 with power ON (set-on) and a voltage is fed to a horizontal drive TR 12 from a power supply circuit 1 via a +B rectifier output circuit 3 and a horizontal drive resistor 13. A standby signal control TR 14 is turned on by a standby signal 9 in the standby and a terminal of the horizontal drive resistor 13 at the side of a horizontal drive transformer 12 goes to a ground potential, then the horizontal drive transformer 12 reaches zero potential and a horizontal system deflection circuit 6B stops its operation. The +B system load circuit 6A reaches a light load in this case, but since the horizontal drive resistor 13 acts similarly as the dummy load circuit, the power supply circuit 1 is operated normally.
