Title: Catalytic deodorizing device
Inventor: SARASHINA HIROTAKA
IPC: A61L9/00
Filed: 2003-06-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a catalytic deodorizing device capable of varying the amount of ultraviolet rays generated from a discharge device according to odor concentration.  <P>SOLUTION: This deodorizing device is provided with a discharge voltage variable circuit 32 varying the amount of discharge of the discharge device according to the odor concentration sensed by an odor sensor 34. When the odor concentration is lowered, the reduction of the amount of the ultraviolet rays generated from the discharge device can reduce the costs such as unnecessary electrical charges. When the odor concentration increases, the increase in the amount of the ultraviolet rays generated from the discharge device can quickly decompose the odor components. The lowering of the odor concentration reduces the amount of the discharge of the discharge device to reduce not only the amount of the ultraviolet rays but also the generation amount of ozone. This constitution can thus prolong the service life of ozonolysis catalyst necessary for the ozonolysis.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: H04W48/18
Filed: 2003-06-30
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a radio apparatus which reduces the quantity of a volatile memory and the power consumption.  <P>SOLUTION: The radio apparatus 100 uses MRAMs which have high read and write speed and do not lose the memory contents with power off for nonvolatile memories A114 and B115. This eliminates the need to copy programs in a rewritable memory from a non-rewritable memory, every time the apparatus is powered on. Thus, in designing a modem LSI 110 for a radio terminal 100, the quantity of a volatile memory can be greatly reduced, compared with the conventional modem LSI. Since the volatile memory consumes power largely, the power consumption is reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
