Title: Air cleaner
Inventor: HARA SHINICHI
IPC: B60H3/06
Filed: 1993-12-20
Abstract: PURPOSE:To provide an air cleaner having the same dust collecting performance whether for fine or for rainy weather. CONSTITUTION:An atmospheric pressure sensor 3 detects atmospheric pressure and a microcomputer 5 takes in periodically the atmospheric pressure value. In the microcomputer 5, a weather forecasting section 51 forecasts the weather on the basis of the atmospheric pressure value and a voltage controlling section 53 controls a power supply section 7 according to the weather. Thus, the power supply section 7 applies high voltage in fine weather and low voltage in rainy weather to a electrostatic precipitation section 9, so that the electrostatic precipitation section 9 displays a strong dust collecting force in fine weather and functions with a moderate dust collecting force in rainy weather.

Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for the manufacture of a printed wiring board which is formed by sticking a plating catalyst containing palladium to the insulating layer on the surface of a substrate, then forming a first plating film, etching the first plating film to form conductor circuits, and subsequently forming a second plating film on the conductor circuit, and a method which is resistant to short circuit failure even if the circuit pattern has a small distance between conductor circuits. SOLUTION: A first plating film is etched to form conductor circuits on the surface of a substrate, and the conductor circuits and the area between the conductor circuits are covered with insulating resin. Thereafter, the surficial portion of the insulating resin is removed to expose the conductor circuits, and the area between the conductor circuits is left as covered with the insulating resin. Then, a second plating film is formed on the exposed conductor circuits. As a result, the second plating film is prevented from depositing using the plating catalyst remaining in the area between the conductor circuits as nucleus during a plating process for forming the second plating film.
