Title: Engine-driven type heat exchanger
Inventor: NAKAMURA MASAHIKO
IPC: F25B27/02
Filed: 1988-07-30
Abstract: PURPOSE:To miniaturize a cooling fan and protect a silencer from being corroded by detecting cooling water temperature to control the exhaust gas flow of a bypass pipeline attached to an exhaust gas heat exchanger. CONSTITUTION:A variable valve 9 is provided in a bypass pipeline 15 to perform the opening control of the variable valve 9 on the basis of a detecting signal of a water temperature sensor 11. When the temperature of cooling water increases, the variable valve 9 is opened and an exhaust gas quantity which passes through the bypass pipeline 15 and is released in the outside through a silencer 3 increases. Therefore releasing heat quantity from a radiator 4 does not exceed the fixed quantity and exhaust heat alone from an engine 1 is released from the radiator 4. Further, since exhaust gas temperature of the silencer 3 is not equal to or lower than the fixed value and kept high, the production of drain is controlled not to corrode the silencer 3. Further, since the releasing heat quantity of the radiator 4 reduces, a cooling fan for the radiator 4 can be miniaturized.

IPC: G06F3/06
Filed: 1993-07-30
Abstract: PURPOSE:To shorten the restoring time of a misplacing fault, to evade the collisions of madia during the restoration processing, and also to prevent the system down caused by the inhibition of the accessor operation that also produces a CE all fault when a fault of an interface system overlaps the misplacing fault. CONSTITUTION:When a misplacing fault occurs, a transfer control means (accessor controller) 56 stores the medium held by a transfer device 12-1 in a 1st saving cell 98. At the same time, the means 56 takes out another medium of a transferred side cell and stores this medium in a 2nd saving cell 100. Then the means 56 stores the misplaced medium information 90 showing that the media are stored in both cells 98 and 100 and finishes the misplacing fault. When a fault of an interface system occurs, the presence of absence of both transferring and transferred side media is checked with use of an alternative path. If no medium is conformed in both side cells, the information 90 is checked. Then the medium is transferred to the transferred side cell from the cell 98 to restore the fault of the interface system as long as a medim is confirmed in the saved side cell.
