Title: Humidifier
Inventor: OGURA FUMIO
IPC: F24F6/00
Filed: 1989-07-24
Abstract: PURPOSE:To prevent dew formation as far as possible even when the room temperature drops, by a method wherein a detected humidity is compared with a set humidity by a comparison means when the detected humidity exceeds a certain humidity and a correction means is provided to correct the set humidity to a lower one. CONSTITUTION:A detected humidity from a humidity detecting circuit 11 and a set humidity from a humidity setting circuit 12 are supplied to a comparator 14, and a detected room temperature from a room temperature detecting circuit 13 is sent to a correcting device 15. The correcting device judges whether the detected room temperature is lower than 10 deg.C, between 10-20 deg.C or over 20 deg.C. When it is lower than 10 deg.C, the set humidity input in the comparator 14 remains unchanged. When it is between 10-20 deg.C, the set humidity input in the comparator 14 is corrected to a lower value by 5%. When it is higher than 20 deg.C, the set humidity input to the comparator 14 is corrected to a lower value by 10%. Therefore, when the ambient temperature is high, the ambient humidity is kept lower than the set temperature and the moisture content in the air is relatively reduced, so that an excess moisture content is reduced even when the ambient temperature drops, resulting in preventing dew formation as far as possible.

Abstract: PURPOSE:To unnecessitate the adjustment of an attenuation circuit, to enable the operation from DC to a high frequency and to make operating temperature a wide range by composing the attenuation circuit by a first FET and a resistor and a second FET and a resistor and impressing a voltage by using a correction circuit for the gates of these FETs. CONSTITUTION:In an attenuation circuit 10, when Vc<Vmo is made by changing control voltage Vc, the voltage Vg of the output terminal 32o of a differential amplifier 32 or the gate voltage Vg of an FET 18 is reduced, the resistance value between the source 18s and the drain 18d of the FET 18 is increased, output voltage Vmo is increased and Vc=Vmo is made. Conversely, when Vc<Vmo is made by changing voltage Vc, the resistance value between the source 18s and the drain 18d is decreased by increasing voltage Vg and Vc=Vmo is made by decreasing voltage Vmo. Thus, voltage Vc and output voltage Vmo is made to be proportional, attenuators 16 and 22 are made to have the same characteristic and the same voltage Vg is impressed on the gates 12g and 18g of the FETs 12 and 18 by using a correction circuit 24.

Abstract: PURPOSE:To prevent the pulsation of delivery flow rate for dimisnishing vibration and noise by a method wherein a conical rotary vane is mounted free to rotate on an axis and protrusions are formed on the surface of the rotary vane. CONSTITUTION:A rotary shaft 10a on the base of a conical rotary vane 10 is fitted in a base plate 1 so that the rotary vane is free to rotate in a pump main body 2, and two or more protruding and recessed parts are formed on the outer surface of the conical rotary vane 10 in the axial direction.

When the conical rotary vane 10 makes a turn, the drain to be discharged outside from a discharge port 4 receives the delivery pressure eight times since the conical rotary vane 10 has eight protrusions 11, so that the drain is discharged with a pulsation of the delivery flow rate diminished to about one-fourth. Therefore, vibration and noise during operation is remarkably reduced and a quiet operation can be achieved.
