Title: Catalyst for purifying exhaust gas and production thereof
Inventor: HAMADA IKUHISA
IPC: B01J23/755
Filed: 1991-11-15
Abstract: PURPOSE:To obtain a catalyst for purifying exhaust gas excellent in exhaust gas purifying capacity and having high reliability by plating a specific paper honeycomb with Ni-base metal by a chemical plating method and burning up the pulp component of the paper honeycomb to form a metal honeycomb base material and supporting a catalytic component having oxidizing activity on said base material. CONSTITUTION:A paper honeycomb consisting of a non-combustible inorg. fiber, inorg. particles 5 with a specific surface area of at least 30m<2>/g or more and pulp is plated with Ni-base metal by a chemical plating method and the pulp component of the paper honeycomb is burnt up to form a metal honeycomb base material and a catalytic component having oxidizing activity is supported on said base material to form a catalyst for purifying exhaust gas. Since paper pulp is mainly used as a substrate material capable of being burnt up, a state such that inorg. particles 5 having a high specific surface area are present in the voids generated at the parts where the paper pulp is originally present along with the plating layer 3 suitable as a catalyst carrier is developed by combustion. Further, the fibrous inorg. substance keeps the strength of the plating layer 3 or honeycomb structure after the paper pulp is burnt up.

Title: Cleaning of ultrafilter film
Inventor: ISHIDA KOJI
IPC: B01D65/02
Filed: 1987-11-28
Abstract: PURPOSE:To allow no deterioration of the recovery rate of water transmission volume by stopping the supply of water containing sludge to an ultrafilter at a prearranged time interval and supplying cleaned water containing no sludge to the sludge-containing water supply side of the ultrafilter. CONSTITUTION:Water to be treated containing sludge is supplied under pressure from a bioreactor tank 1 which biologically treats water using an activated sludge to an ultrafilter 2, and the treated water is separated into concentrated sludge and filtered water. Part of the filtered water is stored in a storage tank 3 for cleaning the ultrafilter 2. When this ultrafilter 2 is cleaned, the supply of treated water to the ultrafilter 2 is stopped by closing the first operating valve V1 at an interval of at most 24hr. Next, the second operating valve V2 is opened to supply cleaned water from the storage tank 3 to the treated water supply side of the ultrafilter 2 for about 30-60sec continuously. In this way, the pressure density of a gel layer does not increase at an interval of max 24hr and the gel layer on the surface of a filter film is broken down even without use of a chemical. Consequently, the recovery rate of the water transmission volume is maintained at a high level.

Title: Character reader
Inventor: YAMAMOTO TAKAHARU
IPC: G06F3/048
Filed: 1988-11-29
Abstract: PURPOSE:To read characters in accordance with the writing speed of a person in writing by using a limit time correction means to correct the limit time in response to the non-contact time. CONSTITUTION:A digitizer 11 inputs the writing action information, and a non-contact time arithmetic means 14 calculates the non-contact time between the writing action information equivalent to one writing action and that equivalent to the next one writing action. Then the completion of the input of one character is decided when the non-contact time exceeds its limit value. Furthermore, a limit time correction means 19 corrects the limit time in response to the non-contact time. Thus the limit time can be corrected in accordance with the value of the non-contact time set by a person late in writing or one fast in writing, respectively. Therefore, the waiting time is shortened between a character and the next character and the operability of a character reading device is improved.

Abstract: PURPOSE:To increase the amount of generated steam and improve the yield of lump coke by calculating the necessary amount of air for burning combustible gas in a circulating gas from the difference between the target steam generation and the real steam generation and blowing the calculated amount of air, thereby effecting the complete combustion of the combustible gas. CONSTITUTION:Red-hot coke discharged from a coke oven is charged into a quenching oven 1 and quenched by blowing cooling gas. The gas heated by the heat-exchange is introduced into a waste-heat boiler 10 and the cooled gas is again blown into the quenching oven 1. In the dry-coke quenching facility having the above mechanism, the amount of air necessary for burning the combustible gas in a circulating gas is calculated from the difference between the target steam generation and the real steam generation and the calculated amount of air is brown into the flue 7 and the outlet duct 8 of the quenching oven at the same time. The combustible gas in the circulating gas of the dry- cake quenching facility is completely burned by this process to increase the steam generation by the waste-heat boiler and improve the yield of lump coke.
