摘要： PURPOSE: To provide a stationary vacuum cleaner capable of freely selecting the installing position of a cleaner body of a vacuum cleaner installed outside a room relative to the outer wall surface. CONSTITUTION: An internal body having a suction device and dust collecting function is received in an upper outer case 11 and lower outer case 12 to provide a drip-proof structure installed outside a room. The outside of the outer case formed into a plane is located parallel to the outer surface of a wall 1 of a building, while a suction port 15 of a cleaner body 4 is located parallel to the outer surface of the wall 1 and at the approximately same height as a hose inserting port 2, and the roof of the outer case is shaped into a shed-roof type. Then, since the installing position of the cleaner body can be freely selected on the outer surface of the wall, the cleaner body can easily be installed even in a place of a small space undesirable in efficiency of installation.

摘要： PURPOSE:To safely perform normal operation, coping with a plurality of commercial power source voltages by changing over and inputting the commercial power source, according to the voltage of the commercial power source. CONSTITUTION:When a power source switch 11 is made, the voltage of 200V is conducted to a voltage detection means 9. Hereupon, the voltage detection means 9 checks whether the conducted voltage is in the vicinity of 200V or not. As a result, in case that it is true, the voltage detection means generates an H level of digital signal and in case that it is false, it generates a low level of signal, and transmits the output to a power changeover means 10. Thereupon, the commercial power source 12 of AC 200V is connected to the 200V taps on the primary sides of the transformers of the motor power source 17 inside the voltage control means 7 and the control power source 18, and on the secondary sides prescribed voltages, that is, motor power source DC 80V and control power source DC 5V occur, and the robot can perform normal operation.

摘要： PROBLEM TO BE SOLVED: To shorten the transfer time from a transfer carriage to a cassette reception opening, by rotating two first arms in the same direction so that rotational movement of a holder loaded with a wafer cassette is rotated in reverse direction for straight movement in radius direction. SOLUTION: Rotating a first right arm 1 and a second left arm 2 in reverse directions causes reciprocal movement of a holder 9 in a direction of an arrow 14. Rotating the first right arm 1 and the second left arm 2 in the same direction causes rotational movement of the holder 9 shown with an arrow 14. The combination of the reciprocal movement and rotational movement allows access to object allocated around. The rotational force of a shaft 10 of the first left arm 2 is conveyed to the second right arm 3 through an upper wire 11 and a lower wire 12, for escaping from straight line positions. Providing the entire vertical drive system shown with an arrow 15 in a box 6 allows vertical driving of the holder 9. Thus, transfer time from a transfer carriage to a cassette reception opening is shorted.

摘要： PURPOSE:To easily establish an origin position by moving an arm toward an origin detecting sensor, ending movement on a pulse for an origin detection phase which occurs near a spot separating as far as the stored number of pulses from a mark position, and regarding counter value at the spot as the stored number of pulses to end origin mating. CONSTITUTION:The number A of pulses, from a point of time when a pulse generates in the origin detection phase of an encoder 2 which first occurs at spot where the output pulse of the encoder 2 separates more than a specified pulse from the mating mark of an arm up to an origin detection sensor 12, is previously stored in a memory circuit 23 at the time of the first registration of an origin position. After the second registration, the number A of pulses is loaded onto the counter 22 of a detecting circuit at the spot where a pulse 25 issues for the origin detection phase occurring at a spot where the output pulse of the encoder separates more than a specified pulse from the mating mark of the arm for completing the mating of an origin point.

摘要： PURPOSE:To prevent the malfunction of a motor at the time of the breaking of a signal transmitting-receiving element by separating a motor drive-direction signal from a PWM signal and stopping the motor when the duty ratio of the PWM signal is brought to zero. CONSTITUTION:Information in the current and drive directions output from a servo control section 1 is received by the analog current command forming means 2 of a motor drive section 2, and converted into an analog current command signal having polarity and transmitted to a current error amplifying means 5. The analog current command signal having polarity represents the signals of motor stoppage at OV, motor forward rotation at positive V and motor reverse rotation at negative V. The difference of motor currents detected by a current detecting means 4 and a current command signal is acquired by the current error amplifying means 5, and amplified and transmitted to a motor driving-pulse generating means. When the difference of motor currents and a current command value is zero, an output is at OV. Transistor driving pulses in width proportional to input voltage are generated by a motor driving-pulse generating means 6, and a motor 8 is driven through a motor driver 7.
