Abstract: PURPOSE: To restrain gathering and growing of steam bubbles by arranging unit structures of direct heat exchanging perpendicularly in some number above a low boiling point medium supply part and a thermal medium supply part and providing openings for the low boiling point medium and the thermal medium supply part in their lower ends.  
     CONSTITUTION: Low boiling point medium 7 and thermal medium 6 to be introduced into a trunk 1 are supplied to the lower ends of cylinders 11c from upper faces 8a and 10a of these medium supply parts through these medium injecting small tubes 8c and 10c. Meanwhile, both mediums 7 and 6 are injected into cylinders 11c to exchange heat directly, and the low boiling point medium is evaporated into steam bubbles 7b to rise in the thermal medium 6. The thermal medium 6 and the bubbles 7b are conducted into cylinders 11b, where operated thermal medium 6a is separated and discharged. Then steam bubbles 7b are conducted into cylinders 11a, where operated medium 6a is separated and discharged. The steam bubbles 7b risen up to the cylinders 11a are discharged to the outside through a bubble separator 12 as generated steam 7a. This construction serves to restrain gathering and growing of steam bubbles.

IPC: H04M1/00
Filed: 1990-02-28
Abstract: PURPOSE:To discriminate the reason of usual error by displaying the arrival of a call when a catch-phone signal comes during data communication and replying the call automatically. CONSTITUTION:When a telephone set C makes a call to a subscriber's equipment B during data communication, a catch-phone signal (a) comes to the subscriber's equipment B, resulting that the catch-phone signal (a) is detected by a catch- phone signal detection circuit 6 and sent to a CPU 7. The CPU 7 detects it as an interrupt signal and allows a display section 10 to be displayed and a changeover switch SW is thrown to the position of a speech circuit 3 to make communication with a telephone set C. When the catch-phone signal comes during the data communication in this way, the incoming display is implemented and the call is replied automatically, the reason why a communication error takes place is discriminated during the data communication.
