IPC: B01D46/24
Filed: 1993-10-21
Abstract: PURPOSE:To manufacture a thin-walled dust removing filter of high heat resistance and corrosion resistance usable in the corrosive atmosphere of high temperature with little pressure loss. CONSTITUTION:A filter is composed of a CVD coating layer of SiC, Si3N4, Al2O3 or C on the fiber surface of a fiber formed body of SiC, Si3N4, Al2O3 Al2O3.SiO2 or C and the surface of the fiber formed body is napped prior to forming the coating layer. The filter, therefore, is provided with superior heat resistance usable at the high temperature of 1000 deg.C or over. As the fiber formed body is used as a substrate, the thin-walled filter is provided with sufficient mechanical strength and large void content and with little pressure loss. The pressure loss is reduced further by napping. A coating layer of high purity, high corrosion resistance and high heat resistance is formed on the surface by means of the CVD process, and the filter can be used sufficiently in the corrosive atmosphere such as HCl at the high temperature.

Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a radio set and a radio system which can be automatically turned on for listening to the broadcasts in a simple constitution and also can easily receive the radio broadcast of a single station with high efficiency. SOLUTION: A switch means 15 is kept in an OFF state as long as a cup 1 is kept on a desk, etc. When an opening 13 is put near an ear, an actuation rod 17 protrudes over the lower edge of the cup 1. Thus, the means 15 is turned on to switch on a power supply. Then the broadcast signals of a specific FM station received by a radio receiving module 2 are converted into the sound signals via a speaker 11. The second of the FM station are outputted and can be clearly heard owing to the screening effect of external noises that is secured by almost a conical structure of the cup 1. This hearing efficiency can be improved despite a compact structure of the speaker 11. Furthermore, the means 15 is automatically turned off when the cup 1 is placed vertically and accordingly the power consumption is reduced for increase of the battery life.
