In this case, the DC voltage is also impressed on a thermo-module 10, therefore, heat is deprived from the heat absorbing body 15 and is radiated to a heat sink 11 whereby the heat is discharged into atmosphere by fins 12. In this case, the food 14 in the case 7 is cooled through the heat absorbing plate 9. When the food 14 is kept in cooled condition thereafter, both of the thermo-module 10 and the magnet 19 are put OFF, therefore, the attracting force of the iron piece 16 is eliminated, an air layer, having a gap H, is produced between the heat absorbing plate 9 and the heat absorbing body 15 and the heat conductivity therebetween is reduced, therefore, counterflow of heat from the heat sink 11 into the heat absorbing plate 9 may be reduced remarkably.

Inventor: IWASAKI NORIO
IPC: B41J2/015
Filed: 1980-02-27
Abstract: PURPOSE:To enhance the response characteristics of the amount of ink jetted by a method wherein a through-hole provided in an air passage extending from an air valve to a nozzle is closed or stopped according as a recording voltage signal increases or decreases. CONSTITUTION:When the air pressure in an air introducing chamber 13 is increased by opening of the air valve 4 of an actuator 1 as a result of a rise in the recording signal in correspondence with a higher-density part of image information, a valve member 32 closes the through-hole 31a to accelate the sucking-out of ink via an ink nozzle 16. On the other hand, when the recording signal is lowered in response to a lower-density part of the image information, the air valve 4 is closed, the air pressure in the chamber 13 is lowered, and the valve member 32 returns to its original position due to the flexibility of its own to open the through-hole 31a, thereby restricting the sucking-out of ink via the nozzle 16.
