Title: Rapid catalyst warm-up control device for internal combustion engine
Inventor: NOGAMI HIROYA
IPC: F01N3/20
Filed: 2006-07-13
Abstract: <P>PROBLEM TO BE SOLVED: To improve rapid catalyst warm-up performance while reducing emissions during rapid catalyst warm-up control.  <P>SOLUTION: Rapid catalyst warm-up control is divided into three stages according to the degree of catalyst warm-up progress. The initial period of the rapid catalyst warm-up control, when a low catalyst temperature develops almost no oxidation reactions, employs the first stage of warm-up control of controlling an air-fuel ratio near the stoichiometric level to provide a maximum combustion temperature of an internal combustion engine, to warm the catalyst with high temperature exhaust gas. When the catalyst is warmed enough to start to oxidize and control rich components in the exhaust gas, the second stage of warm-up control of controlling the air-fuel ratio to a slightly lean side is selected. The catalyst then oxidizes rich components in the exhaust gas, and the heat of reaction warms the catalyst. When the catalyst is half warmed up, the third stage of warm-up control is selected to provide dither control of varying the air-fuel ratio alternately to lean and rich sides until the catalyst is fully warmed up.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Title: Bacteria concentration and sterilization device and method
Inventor: UCHIDA SATOSHI
IPC: B01J19/08
Filed: 2006-07-14
Abstract: <P>PROBLEM TO BE SOLVED: To solve such a problem involved in the conventional high voltage pulse sterilization that a gap between electrodes for applying a pulse is not made small, and a high voltage pulse therefore is necessary in order to generate an electric field of about ≥10 kV/cm required for physically destroying bacteria, and since bacteria are scattered in fluid, even a high voltage pulse is applied to the fluid, the pulse is not always applied to bacteria and can not kill the bacteria in a lot causing low sterilization efficiency.  <P>SOLUTION: An AC power supply is applied to a space between electrodes 4, 5, and bacteria 9 in fluid at a flow passage 6 are collected by dielectrophoresis (bacteria concentration). When the bacteria concentration reaches a prescribed concentration, a detection signal is emitted from a bacteria concentration detection part 13, and a pulse power source 12 is applied to an electrode 10 and the electrodes 4, 5. The bacteria are killed in a lot, and pulse voltage can be made low when the gap G in the flow passage 6 is made small, thus satisfactory sterilization efficiency is obtained.  <P>COPYRIGHT: (C)2008,JPO&INPIT
