IPC: H05K3/46
Filed: 1990-04-02
Abstract: PURPOSE:To stabilize surface condition and reduce the fraction defective of an inner layer member by integrally laminating the inner layer members which are copper sticked double-sided laminated plates to which chemical cleaning processing is applied by using a chemical polishing liquid which contains an acid and an oxidizing agent as main components, a reaction accelerator added as required and chlorine at a content not larger than a prescribed value and outer layer members via resin impregnated base material sheets. CONSTITUTION:Inner layer members which are copper sticked double-sided laminated plates to which chemical cleaning processing is applied by using a chemical polishing liquid and outer layer members are integrally laminated via resin impregnated base material sheets. The chemical polishing liquid contains an acid, such as sulfuric acid, an oxidizing agent, such as hydrogen peroxide, both as main components, and a reaction accelerator added as required. A chlorine content is required not to be larger than 180ppm. This is because scatter is generated in surface configuration and roughness when the chlorine content exceeds 180ppm. As means for restraining the chlorine content to a value which is not larger than 180ppm, it is favorable to supplement the quantity of the chemical polishing liquid with pure water, to remove an increased chlorine quantity by an ion exchange substance or by adsorption by an active carbon membrane.

Title: Cleaning device
Inventor: KOBAYASHI KAZUO
IPC: B01D29/62
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning device which is capable of maintaining an outstanding filtration capability over a long stretch of time by efficiently cleaning a filter automatically. SOLUTION: A thread-like filter medium 3 is wound in such a way that it is shrinkable or expandable under the pressure of a water to be treated passing through a filter. Therefore, at the time of cleaning, the water passes through the filter medium 3 after entering a first channel 13 and makes the filter medium 3 afloat from a cylindrical member 2 due to the pressure of the water heading for a second channel 12 to spread the mesh of the filter medium 3. Thus it is possible to remove a soil as a cause for clogging.
