Abstract: A heat exchanger includes a distributor; a plurality of heat-transfer tubes; and a refrigerant inflow pipe. The plurality of heat-transfer tubes connected to the distributor stick out into an internal space of the distributor such that when the plurality of heat-transfer tubes and a part defined as the internal space are projected on a plane perpendicular to an axial direction of the distributor, the plurality of heat-transfer tubes occupies one-half or greater of the part defined as the internal space. The distributor includes an orifice plate and dividing the internal space. The orifice plate is located above the lowest one of the plurality of heat-transfer tubes in the internal space. The orifice plate has an orifice through which the upper and lower spaces communicate with each other.

Abstract: An electronic mail monitoring apparatus executes a plurality of processing. When the verification processing has judged that the uniqueness number of information for each of the user identification information calculated by the calculation processing has exceeded a first threshold, the calculation processing calculates a uniqueness number of countries or regions on the basis of the identification information for each user identification information extracted by the extraction processing within a unit time. The verification processing judges whether the uniqueness number of countries or regions for each of the user identification information calculated by the calculation processing has exceeded a predetermined second threshold.

Abstract: An extraction section (102) extracts user identification information and communication terminal identification information from electronic mails acquired by an acquisition section (101). Then, a calculation section (103) calculates a uniqueness number of the communication terminal identification information for each of the extracted user identification information. Then, a verification section (104) judges whether the uniqueness number of communication terminal identification information for each of the calculated user identification information has exceeded a predetermined threshold. Then, for each case, a notification section (105) performs predetermined notification to a notification destination set up in advance.

Abstract: A monitoring device monitors operation states of servers. If information that indicates the operation states is requested from a supervisor terminal, the monitoring device generates display information that allows the supervisor terminal to graphically display the operation states and process commands for the servers and transmits the generated display information to the supervisor terminal. If process commands are transmitted from the supervisor terminal, the monitoring device causes the servers to execute processes based on the transmitted commands.
