Title: Air cleaner
Inventor: MIZUNO KEIICHI
IPC: A61L9/015
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a safe air cleaner which never releases ozone when an ozone concentration detecting means is broken by constituting a control means in such a manner as to control an ozone generating means to generate ozone when the ozone concentration detecting means is operated. SOLUTION: A signal of an ozone concentration detecting means 1 is received by a control circuit, which controls the operation of a high voltage generating means 12 and a blowing means 2 on the basis of this signal. The high voltage generating means 12 applies a high voltage to an electric dust collector 14 to generate ozone in the electric duct collector 14, and the ozone is decomposed by an ozone decomposing means 3. When the ozone concentration reaches a set value or more, the ozone concentration detecting means 1 outputs a signal 0. When the signal of the ozone concentration detecting means 1 is 0, the high voltage generation and blowing for generating ozone are stopped. Namely, the operation of an air cleaner is stopped. When the ozone concentration detecting means 1 outputs no signal by the occurrence of an abnormality, the abnormality is displayed, and the operation is stopped.

Title: Reverse syphon type heat transmission system
Inventor: KIKUCHI KENTAROU
IPC: F28D15/02
Filed: 1984-03-30
Abstract: PURPOSE:To conduct heat transmission from the upper part to the lower part, by a method wherein a liquid reservoir is provided at the place upper than an evaporating part within en route of a return passage which introduces condensed fluid from a condensing part while a check valve is provided on a return passage between the reservoir and the evaporating part. CONSTITUTION:In the daytime, heat medium 4 becomes steam by the sun applied to the evaporating part 1. Steam enters the lower condensing party through an outward passage 10. The heat of steam is transmitted still more from water 7 to a cold water tank 9. Water in said tank 9 becomes hot water by absorbing heat, and is used in a building 2. Condensed fluid is moved under pressure so as to rise a returning passage 11. While the pressure of steam at the evaporating part 1 is high, the check valve 13 closes the return passage 11 in the manner that the steam does not flow reverse towards the reservoir 12. Accordingly, condensed fluid is storaged in the reservoir 12. While at night, the evaporation of heat medium becoming very small, the pressure of steam at the evaporating part 1 gets low, and the check valve 13 is opened, and condensed fluid in the reservoir 12 drops into the evaporating part 1 under gravity.

Abstract: PURPOSE:To increase an output current successively by using the output signal of an AC Wheatstone bridge circuit consisting of a variable resistance and a capacitor as the gate signal of a thyristor or bidirectional conductive triac and applying the current, which is flowed by switch on, to a resistance changing device of the Wheatstone bridge circuit. CONSTITUTION:An AC voltage is applied to the Wheatstone bridge circuit consisting of resistances R1 and R2, a capacitor C, and a variable resistance VR; and if the output voltage of this circuit is applied to the base electrode of a transistor TRT through a resistance R4 when the variable resistance VR has a maximum value, the voltage generated in the secondary coil side of a transformer H1 is applied as the gate signal of a bidirectional conductive triac K, but this triac is not made conductive. The current from a power source transformer H2 reaches a light emitting diode Q from a diode D through a capacitor C4 and resistances R6, R5, and R3, and the resistance value of the variable resistance VR is reduced gradually by light emission of the light emitting diode Q. An output pulse operates the bidirectional conductive triac K to flow a current.
