Title: Method and system for canceling electronic mail
Inventor: GOTO TSUNEHISA
IPC: H04L12/58
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To prevent an electronic(E) mail transmitted to an error destination address from being opened by an owner of an information processing terminal of the address. SOLUTION: An E mail server 51 transmits a normal E mail transmitted from a client 71 to an E mail server 52. Also when an E mail cancel requesting E mail is transmitted from the client 71, the server 51 executes similar processing. At the time of receiving a normal E mail, the server 52 temporarily stores the received E mail in a prescribed storage area, and after the lapse of prescribed time, transmits the E mail to a client 91. At the time of receiving the E mail requesting the cancel of the E mail before the lapse of the prescribed time, the server 52 respectively verifies two digital signatures in the cancel requesting E mail by using a disclosed key for verifying a user's digital signature previously provided from the client 71 to check whether the signature is altered or not and whether a transmitter is the same or not.  When the signature is not altered and the transmitter is the same, the contents of the normal E mail are compared with that of the cancel requesting E mail, and when both the contents are different from each other, the normal E mail is canceled in accordance with the contents of an instruction described in the header part of the cancel requesting E mail.

Title: Method of fluidized combustion
Inventor: HIRAMA TOSHIMASA
IPC: F23C10/00
Filed: 1981-05-12
Abstract: PURPOSE:To make pre-treatment of pulverizing coal into small size unnecessary, to decrease NOx content, and to increase combustion efficiency of a fluidized furnace, by fluidize-burning coal of low quality level as it is of a diameter of coarse grain without pulverizing it, and by utilizing the lime ash itself produced as a result of combustion, as a fluidizing medium. CONSTITUTION:Unpulverized coal being fed into a hopper 1 is fed into a furnace 3 from a coal feed pipe 6. Combustion air is fed into the lower part of a furnace 3. The ash produced in a furnace is discharged to the outside of a furnace from an overflow pipe 14, being collected in an ash pond 15. A part of ash in an ash pond 15 is conveyed to a solid-gas separator 19 from a lift part 17 by a conveying air 18, being fed back into a furnace 3 through a recycle pipe 20. The ash fed back is utilized as a fluidizing medium in a furnace 3. With such an arrangement, a pre-treatment to pulverize coal is unnecessary, and the rate of generation of NOx is decreased, because the coal of larger diameter is more advantageous than the one of smaller diameter, as measures to counter NOx.

Title: Activated-carbon-packed tower having gutter
Inventor: OKAMOTO MASAYOSHI
IPC: B01D53/04
Filed: 1979-06-12
Abstract: PURPOSE: To keep desired adsorbing power and catalytic power of the tower described in the title, by introducing water, condensed at the wall of the tower after the heated gas to be treated having passed through the activated-carbon-packed layer, by way of gutters, set along the wall surface, and drainage pipes to the outside of the activated-carbon-packed tower.  
     CONSTITUTION: A gas introduced through an inlet 2 for gas to be treated is heated by a heater 4 so as to decrease its relative humidity, then it is brought into contact with activated carbon, where it is liberated from harmful components, malodorous  components, and it is discharged through a discharging outlet 3. After having passed through the activated carbon layer 5, the gas collides with inner wall 6 etc. of the packed tower, and the water contained in the gas condenses and flows down along the inner wall of an encircling body 1 into a gutter 7 provided over whole periphery, then it is discharged through discharge outlets 8. Hence the function of the activated-carbon-packed layer 5 is hardly inhibited because the layer 5 adsorbs little condensed water.
