摘要： PURPOSE:To protect semiconductors from breakdown due to excessive current by turning an open/close means OFF for a predetermined time when the wind speed is higher than a predetermined value or when the wind speed is lower than the predetermined value and DC current exceeds over a predetermined value during operation. CONSTITUTION:Intensity of outer wind force is detected through an outer wind speed detecting means 7, and when the detected intensity exceeds over a predetermined level an open/close means 9 is turned OFF for a predetermined time. When the outer wind speed is lower than a predetermined level and the outer wind force increases during operation of a brushless motor 16 thus increasing load on the brushless motor 16, load condition is detected through a DC current detecting means 10 and when DC current exceeds over a predetermined level all elements in a semiconductor switching group 2 are turned OFF for a predetermined time thus preventing excessive current flow through the winding 3 of the brushless motor 16 and the semiconductor switch group 2.

摘要： PURPOSE:To enable the highly precise detection of a remote controller position through a compact system with a few number of parts by providing a signal amplifying means which amplifies, tunes and detects a signal from a signal switching means, and a controlling means which outputs a switch signal to the signal switching means and inputs a level signal from the signal amplifying means, and judges remote controller position. CONSTITUTION:Light receiving elements 1a-1d receive a position detect signal (infrared ray signal) from a wireless remote controller. Selector switches 2a-2d are connected to the light receiving elements 1a-1d. The signal amplifying part 3 amplifies, tunes and detects the weak signals having passed through the selector switches 2a-2d. The level input terminal E of a microcomputer 4 is connected to the output terminal of the amplifying part 3. The output terminal F of the microcomputer 4 is connected to the CLK terminal of a switch control part 2e. Because the signals from plural light receiving elements 1a-1d are amplified, tuned and detected by one amplification circuit 3 according to the switch signal from the microcomputer 4 by using this constitution, and after definite time elapses, the level signal is inputted to the microcomputer 4, noise can be removed sufficiently.

摘要： PURPOSE:To accurately obtain an output signal corresponding to the quantity of light by forming an amplifying circuit which uses a gain output circuit varying the amplification factor of a gain control part having gain attenuation characteristics corresponding to the output signal of a gain output part. CONSTITUTION:Light emitted by a light emission part 9 is received by a light reception part 1 and converted into an electric signal. This signal is inputted to an amplification part 2, amplified by a preamplification part 3, and inputted to the gain control part 4 having such a gain reduction characteristic that the amplification factor is varied according to the output of the gain output part 7. A signal after the frequency of a light signal used for a band-pass filter 5 is selected is inputted to a detection part 6 for converting the input into the output of the gain output part 7. The signal is inputted to a comparison part 8 through the gain output part 7 which feeds the signal back to the gain control part 4 as the output of the gain output part 7. The signal inputted to the comparison part 8 is A/D-converted to obtain the output signal corresponding to the quantity of light.

摘要： PURPOSE:To prevent breakage of transistors, by a method wherein an outout shaft and a rotor can be separated from each other at certain rotational speed or higher of the rotor. CONSTITUTION:An output shaft 1 is connected to a rotor 2 through an inner bearing 8 and an inner shaft 7. That is, the output shaft 1 and the rotor 2 are separated in rotation. Further, a clutch plate 5 is mounted on the output shaft 1, and a clutch board 6 is mounted on top end of the clutch plate. In this constitution, if the motor is rotated and the rotational speed becomes a certain value or higher, the clutch board 6 is moved in arrow direction by centrifugal force, and the output shaft 1 and the rotor 2 are separated thereby only the output shaft 1 is rotated. Even if the output shaft 1 is rotated at high speed by external force, since the rotor 2 is rotated at low rotational speed, breakage of transistors can be prevented.
