Title: Data processor
Inventor: TAKATSUDO YASUHIRO
IPC: G06F1/30
Filed: 1990-04-27
Abstract: PURPOSE:To evade the double working of a data processor after the reapplication of a power supply by providing an address pointer to show the stored position of the data on the operation carried out at present by a machine on an IC card and restarting the operation according to the address value of the address pointer when the operation is restarted with the reapplication of the power supply of a data processor. CONSTITUTION:An address point is set at a part of an IC card 2 to show the data with which a machine 1 is working. The machine 1 sets the head address of the working data to the address pointer when the machine 1 reads the data out of the card 2. If a power supply is cut due to an instantaneous power failure, etc., while the machine 1 is working by reading successively the stored data, the machine 1 reads the data on the storage address shown by the address pointer and starts its operation after the reapplication of a power supply. Thus the machine 1 can start the operation in the state set right before the stop of the machine 1 after the reapplication of the power supply even if the power supply is cut due to an instantaneous power failure, etc.

IPC: F04F5/26
Filed: 1978-09-13
Abstract: PURPOSE: To improve the effiecincy of the suction of an ejector, by adding negative pressure generated by the rapid decrease of the volume of steam to negative pressure produced by steam injected.  
     CONSTITUTION: When steam is injected into diffusers 22W24 from each steam injection nozzle 25a, 26a, 27a, negative pressure is generated in each chamber body 2W4, and air currents sucked containing a steam component are absorbed from a suction pipe 9. When the air currents sucked flow into the chamber body 2 at the lowest stage and pass through a condensation portion 10, the steam component is heat exchanged by cooling water from nozzles 15 and condensed, and condensation and cooling water are discharged from a drain pipe 18. Thus, negative pressure in the chamber body 2 at the lowest stage increases and sucking force augments by the condensation of the steam component and the sudden decrease of the volume of steam. The air currents sucked reaching upper space 16a after passing through the condensation portion 10 flow into the lower space 16b of the chamber body 3 at the intermediate stage with steam from the nozzles 25a, and pass through a condensation portion 11 in the same manner as mentioned above.
