Abstract: PURPOSE:To construct an air flow controller of a fan capable of increasing the comfortable feeling for a user by memorizing control of operation in which a selected speed control notch and the selected speed control notch lower than the former by one stage are repeated in a constant interval. CONSTITUTION:When 'strong' is selected by the operating switch of a fan 1, a microcomputer outputs a signal to continue the operation of the speed control notch of 'strong' of the motor of the fan 1 in a certain constant interval T. Next, after the constant interval T passes, the signal is changed to the speed control notch of 'middle' which is a lower notch by one stage, after the operation of the constant interval T, the control of 'strong' and 'middle' is repeated in the constant interval T. Similarly, at the time of selecting 'middle', 'middle' and 'weak' are repeated, at the time of selecting 'weak', 'weak' and 'feeble' are repeated, same as the case of 'strong', such a control is repeated in the constant interval T. Consequently, the operation of a selected speed control notch and the speed control notch lower than the former by one stage are repeated in constant interval T, the power spectralness of the wind velocity thereof can obtain comfortable wind without abrupt feeling because wind velocity power approaches a l/f straight line in a low frequency zone.

A peak is not found on the boundary of the electrode 12 and air. The obvious difference in the intensity distribution of reflecting wave is thus found according to the quality of the soldering condition and the joining condition can be inspected non- destructively and surely.

IPC: D06F33/02
Filed: 1988-08-29
Abstract: PURPOSE:To eliminate the need to change a part even when a frequency is different and to approximately uniformize dehydration performance by providing a control means which continuously energizes a drive motor when the frequency of a commercial source is 50Hz and intermittently energizes the drive motor when it is 60Hz. CONSTITUTION:When, in dehydration operation, a commercial source 8 is 50Hz, a signal is outputted from a microcomputer 15 to a drive circuit 18 and a gate signal is continuously provided to a triac 13. Thus, with a drive motor 7 run, a rotary drum 4 is continuously rotated for a given time through a belt transmission mechanism 9 and a mechanism part 6. When the commercial source 8 is 60Hz, the microcomputer 15 decides the number of revolutions of the drive motor 7 from a phase difference signal. When the number of revolutions is increased and exceeds the number N of revolutions for 50Hz and is increased to the given number of revolutions (N+alpha), a signal to the drive circuit 18 is stopped for a given time T of three minutes, and the triac 13 is brought into an OFF-state. This constitution decreases the number of revolutions of the driven motor 7 for a while and decreases it to a value lower than the number N of revolutions. The drive motor 7 is run again, the number of revolutions is increased, and in the following, the aboves are repeated.
