Abstract: PROBLEM TO BE SOLVED: To allow a system to execute selective packet abolition by storing an ATM cell as it is when the cell is the head cell of a host layer packet in the case of the state of a logic channel set to '01' and by allowing a cell input control section to abolish the ATM cell forcibly in the case of a state '11'. SOLUTION: A cell input control section 24 refers a management table 30 to forcibly abolish an ATM cell from a logic channel VC in a 'packet retrieval state'. At first, when an ATM cell is inputted by the cell input control section 24, a cell abolish table 30 is refered based on a logic channel identifier VC1 to check the state of an attribute registered in the management table 30. When the attribute indicates '00' (not applicable) or '10' (packet reception enable), the cell is stored in a cell buffer as it is. Finally whether or not the arrived cell is an EOM cell, and when the cell is the EOM cell, so long as the state of the logic channel VC is not '00' (not applicable), the state is changed into '01' (not receiving packet). On the other hand, when the attribute is '11' (aborting), the cell is forcibly abolished.

Abstract: PURPOSE: To combine fluid from the exterior or discharge it to the exterior for adjusting temperature of the fluid by connecting a drive means such as bimetal to a valve body to open and close a valve in response to change in the temperature of the fluid.  
     CONSTITUTION: In a valve 54 for combining and branching fluid flow to adjust temperature of the fluid, when temperature of fluid in a valve chamber 35 is low, bending force of a bimetal unit 43 is small so that a valve body 40 closes a valve hole 39 communicating to a fluid combining or branching port 38 with a coil spring 44. On the contrary when said temperature is high, the bimetal unit 43 extends to compress the spring 44 and the valve body 40 opens the valve hole 39. Such valve 54 is disposed in an intake path 55 of a pump 52 and the flow combining port is connected to a high pressure-low temperature water source 56. In such use of the valve, low temperature water is poured in condensation in the intake path 55 by the action of the valve 54 to cool the condensation when temperature of the condensation is higher than a set value. Thus, necessary minimum amount of cooling water is automatically added so that a feed water pump 52 carries out efficient pressure feed of condensation without cavitation.
