Title: Cooling method of inactive gas
Inventor: IHARA SATOSHI
IPC: F28C3/06
Filed: 1983-12-27
Abstract: PURPOSE:To enable to make the formation of sodium chloride fine particle as little as possible during the cooling of inactive gas by a method wherein high temperature inactive gas is lowered its temperature by being mixed with low temperature gas and, after that, cooled with sea water. CONSTITUTION:Fuel is burnt by a burner 4 at the excess air ratio of 1 or slightly higher tnan 1 so as to turn into high temperature inactive gas and to blow off through opening parts 6c radially and obliquiely downwards and reach a downward convergent conical ring part 7. On the other hand, cold inactive gas enters by a pipe 8 into an annular part 9 surrounding the peripheral wall 6d of a gas producing chamber and flows down to a gas mixing part 7 to be mixed with said high temperature inactive gas. The resultant inactive gas, the temperature of which becomes lower than that of the high temperature inactive gas by mixing, flows down through a down pipe 10 and changes its direction upwards at the lower end of the down pipe into a packed layer 11 so as to be brought into counterflow contact with sea water, which enters by a pipe 12 and pours down from a distributor 13 in order to be turned into low temperature inactive gas. A part of the low temperature inactive gas is sent through a pipe 14 to a gas reservoir and other application facilities, while the remaining part is fed to the pipe 8 by means of a blower 15 in order to be used for the cooling of high temperature inactive gas at the inactive gas mixing part 7.

Title: Recording and reproducing control system
Inventor: TAKEDA MASUYUKI
IPC: G11B15/087
Filed: 1987-10-05
Abstract: PURPOSE:To record/reproduce required data accurately by reproducing a sub- code data through the partial rewinding of a loaded tape in starting the recording/reproduction and comparing it with a sub-code data stored previously in a memory section so as to attain desired recording and reproduction. CONSTITUTION:A reproduction mode is set by the depression of a proper key in a mode setting section 18A and it is commanded to a control section 18. Suppose that the system is in the unloading state, the tape is loaded to wind the tape onto a drum. Then the tape is wound slightly and the signal is reproduced to read a required sub-code. When the content of the read sub-code is coincident with the content stored in the memory section 30, the suppression of a mute section 16 by the control section 18 is released and the substantial reproduction is transited. Thus, the tip of the tape is detected accurately to apply the required recording/reproduction.
