Abstract: A wire gauze filter assembly is disclosed to include an open frame, a plurality of wire gauze filter elements made of paper, nonwoven fabric, fire netting material, or plastics in the form of a meshed, honeycomb, or wave-like structure and mounted inside the open frame, and a filter compound selected from chitosan, photocatalyst, active carbon, nanometered gold, nanometered silver, bee propolis, nanometered TiO2Ag, nanometered TiO2Au, nanometered TiO2Pt, static filter compound, and/or their combination and coated on the wire gauze filter elements.

Abstract: A cleaning device including a sensor, a circuit board, a fan motor, an optical catalyst glass fiber filter mesh, an anion and ozone generator and a power supply. The cleaning device is able to collect dust and remove odor. Also, the cleaning device is able to generate ozone and natural anion to activate human cells and help in blood circulation. In addition, by means of a USB (Universal Serial Bus) signal cable or IBM PS/2 signal cable, the cleaning device can be connected to a personal computer to serve as a peripheral equipment of the computer and form an environmental quality monitoring system. The computer can show the air quality index of the environment. The index can be presented through image or sound of the computer.

Abstract: An air conditioner has a negative ion-filtering device in union for purifying function which comprises a PC board to produce negative ions, a high voltage lead, high voltage electric sheets, and a dust mesh, being positioned behind air blow direction adjusting grill of the air conditioner's front upper face. In use after the temperature adjustment is made, the electric sheets which produce negative ions make the passing dust particles of the air carry negative charges and be sucked attached to the dust mesh producing positive ions, this way achieving purification of the air passing therethrough.

Abstract: A hot and cold compress device comprises a heat transmitted element of which one plate grows hot or the other plate grows cold while the current is conducting, a pair of heat conduct elements which can conduct the aforesaid heat transmitted element to grow hot or cold, an adiabatic tie which sleeves the heat transmitted element and the heat conduct elements, two radiating films which are installed symmetrically to coat the two surfaces of the adiabatic tie, two thermometers which are united on the end of the radiating films, a control box which supplies the power of the heat transmitted element and sets the temperature, and a pair of ties which are connected to the two ends of the adiabatic tie. The feature of the present invention is that the device grows cold at one side of the radiating films, while conducting, to reduce the patient's fever. On the other hand, if the polarity of the power supply is changed and reversed, the other side of the radiating films grows hot to provide the patient a hot compress.

Abstract: An ashtray apparatus comprises a seat having a top rim which provides to place or contain an ashtray and of which inside center is hollow to contain a PC board and batteries, a support rod of which low end is connected a cage cover and also supports it, a cage cover fixing a negative ion emitting needle device and providing a positive ion dust collecting film, a negative ion emitting needle device fixed at the open of said cage cover and a positive ion dust collecting film united on the inner rim of said cage cover. By the connection of aforesaid elements that makes the particle cigarette ashes floating in the smoke through the adherence of negative ion be absorbed and adhered by the positive ion collecting film and be eliminated to reduce the air pollution of inside.

Abstract: The present invention relates to an apparatus for preventing criminal's escape or violence. This apparatus comprises an action box which is united on the criminal's handcuff or fetter and which can endure any general bump or knock and will not be transformed or damaged. There are installed wireless receiving circuit, shock device circuit, buzzer device circuit and battery on the PC board in the action box. The afore-said action box can receive shock order code that is ordered by the control box in the executor's hand. On contrary, when the action box can not receive the signal code, it will sound warning and order shock device to actuate shock to prevent the criminal's escape or violence. Besides, present invention can achieve the purposes of increasing police's safety and saving police's strength.

Abstract: An air conditioning system has a negative ion-filtering device in union for purifying function which comprises a PC board to produce negative ions, a high voltage lead, high voltage electric sheets, and a dust mesh, being positioned in the air blow direction path of the air conditioner for use after the temperature adjustment is made. Electric sheets which produce negative ions make the passing dust particles of the air carry negative charges and be sucked attached to the dust mesh producing positive ions, this way achieving purification of the air passing there-through.
