Title: Gas-steam mixing cycle engine
Inventor: UJI MOICHI
IPC: F01K21/04
Filed: 1978-09-20
Abstract: PURPOSE: To imporve thermal efficiency by making the conception of a complex cycle to be satisfied with one unit of engine and recovering the evaporation latent heat which is given to water in an exhaust gas boiler, in the form of the condensation heat of H 2 SO 4 .  
     CONSTITUTION: The air 21 having been compressed by a compressor 1 is supplied to a combustor 2, and added with fuel 27, and sulfur, or SO 2 28 to form combustion gas in high temperature and pressure. The gas is mixed with the pressurized steam 26 from an exhaust gas boiler 5 and the operation fluid 22 for a turbine 3 is formed. The exhaust gas 22 from the turbine is introduced into a SO 2 -SO 4  converter 4, and SO 2  in combustion gas is converted to SO 3  by catalysts, and the exhaust gas 23 containing SO 3  reacts with steam to form H 2 SO 4  and condenses, providing the condensation heat to the pressurized water 25 in the exhaust gas boiler 5. Thus, through the formation of H 2 SO 4  from the mixed gas consisting of steam and combustion gas, the condensation temperature of exhaust gas 23 in the exhaust gas boiler 5 can be increased higher than the evaporation temperature of pressurized water 25.

Title: Data base file system
Inventor: KITAZAWA ATSUSHI
IPC: G06F12/00
Filed: 1990-05-01
Abstract: PURPOSE:To restore the contents of a data base file in a short time by keeping a history of changes of the transaction related to an updated block to be backed up until a back-up operation is finished at an optional back-up interval and backing up the contents of a data base file. CONSTITUTION:When a data base file 2 has a fault, a file restoring means 12 transfers all contents of a back-up file 7 to the file 2. Then the means 12 transfers all contents (blocks) of a transaction updating history 4 to the corresponding block in the file 2. Therefore it is possible to reflect all updating operations carried out by the transactions occurred at 2nd and subsequent back-up operations to the file 2 at the end of a back-up operation preceding by on time. As a result, the file 2 is restored into the latest state in a short time.

Title: Charge transfer device
Inventor: YUKIMARU MASAKI
IPC: H04N5/372
Filed: 1988-05-12
Abstract: PURPOSE:To shorten time of accumulated charge transfer between neighboring pixels by arranging implanted ion concentration distribution inside an n type Si layer in continuously inclined concentration distribution or fine step-shaped concentration distribution so as to turn a potential well into an inclined well or fine step-shaped well. CONSTITUTION:An inclined potential well or a fine step-shaped potential well is formed inside a p type Si layer by adjusting concentration distribution of ions implanted into an n type Si layer. That is, as for the concentration distribution 8 of ions implanted into the n type Si layer 3, the concentration is increased in monochrome (continuously) inside one pixel along the charge transfer direction. This is similar to all other pixels. By the inclined concentration distribution 8 of this implanted ions and voltage value applied to a gate electrode 1, a potential well 9 to electrons formed inside the p type Si layer 5 becomes such an inclined potential well that the potential may lower to the charge transfer direction. Hereby, the speed vector in the transfer direction of the charge becomes large, and high speed charge transfer becomes possible.
