Title: Ventilating device
Inventor: KAMATA SAKAE
IPC: F24F7/007
Filed: 1980-07-25
Abstract: PURPOSE: To collect a large amount of polluted air excellently, and to discharge air effectively by mounting a controlling means increasing and decreasing the speed of a fan motor and adjusting the speed when an opening area of an opening section of an intake port is enlarged or reduced.  
     CONSTITUTION: The intake opening secton is mounted to a lower section of a ventilating fan proper hood 1. The opening area of the opening section of the intake  port changes variously through the variable opening and closing of a cover 9. A condition (a) that the cover 9 is opened represents an example at the time when there  are much polluted air b generated from an oven, an the motor 3 is turned at high  speed through the controlling means. A condition (b) that the cover 9 is closed  gives an example at the time when there is little polluted air b, and the motor 3 is  rotated at low speed through the controlling means. That is, the velocity of a wind  sucked around the opening section does not lower because the opening area is reduced in response to a turn at low speed even when the motor is turned at low  speed. Accordingly, the polluted air is collected positively and discharged.

Title: Detector of abnormal speed of operation for robot
Inventor: INABA HAJIME
IPC: G05B19/408
Filed: 1982-06-15
Abstract: PURPOSE:To prevent a runaway of a motor when a speed control unit, etc., become abnormal by generating an abnormality signal if a speed deviation signal from a differential absolute value circuit exceeds a set value. CONSTITUTION:Once the motor 5 is driven by the speed control unit 4, a pulse coder 51 outputs a feedback pulse signal according to the rotation of the motor 5 and the signal is applied to an F-V converter 3 through a phase discriminating circuit 14. The signal converted into a voltage is fed back to the unit 4 as a speed feedback signal to control the motor 5 through the unit 4 under a speed command. The speed command Vcmd, on the other hand, is supplied to a simulation signal generating circuit 6 as well to simulate the characteristics of the motor 5. The differential absolute value circuit 7 finds the difference between the output of the circuit 6 and that of the converter 3 and outputs its absolute value as the speed deviation signal Vve. A comparator 8 compares the signal Vve with the set value to generate the abnormality signal when the signal Vve exceeds the set value.
