  • Publication number: 20040213152
    Abstract: Every entry of a flow table has the following fields: a source IP address; a destination IP address; a protocol number; an identification; a source port number; a destination port number; a payload type; and SSRC information. An RTP-judging unit judges, when IP packets having a characteristic of a RTP header have been inputted continuously for predetermined time, that each of the IP packets includes an RTP packet. A packet-classifying unit classifies an inputted IP packet according to a judgment result by the RTP-judging unit and a pre-defined packet-classifying-rule.

  • Patent number: 5176568
    Abstract: There are provided a plurality of groups 14 and 34 which are arranged in an outlet of a main body, and which comprise blowing direction deflecting plates 1, 2 and 3, and 21, 22 and 23; rotational angle setting means 41a and 41b which are provided for the respective groups 14 and 34, and which set rotation angles of the groups 14 and 34; rotational angle limit detection means 42a and 42b for comparing preset limiting rotation angles of the groups 14 and 34 to the set rotation angles; and rotational direction reversing means 43 for reversing the rotational directions of the groups 14 and 34 when at least one of the groups 14 and 34 has reached the limiting rotation angle. Blowing direction of conditioned air can be adjusted while constantly keeping an arbitrary phase difference in blowing direction between the groups.

  • Patent number: 5165250
    Abstract: An air conditioning system comprising a refrigerant circuit. A thermal storage device is arranged in the refrigerant circuit and can store heat and utilize the stored heat to increase heating capacity at the time of kickoff of heating. A temperature detector detects a temperature at a thermal storage portion of a thermal storage and radiating heat exchanger which is housed in the thermal storage device. A counter counts a thermal storage operation period required for the temperature detected at the thermal storage portion to achieve a predetermined value, outputs a signal indicative of stopping a thermal storage operation when the detected temperature has achieved the predetermined value, counts the lapse of a predetermined thermal storage operation stoppage period after stop of the thermal storage operation, and outputs a signal indicative of starting the thermal storage operation when a predetermined thermal storage operation stoppage time has passed.

  • Patent number: 4667074
    Abstract: An induction heating apparatus is formed by connecting a plate or a rod made of good heat-transferring metal to the lower surface of an insulating plate, connecting a spring or a bimetal having shape-memorizing function to one end of the metallic plate or rod and providing a temperature displaying means at a corner portion or an operating part in the front surface of the insulating plate. The induction heating apparatus always displays a correct temperature in an insulating plate even at a high temperature in a cooking pot. Further, there is causing no shaving or peeling-off as seen in a paint in which change in color takes place depending on temperature and a danger of burn can be prevented.

  • Patent number: 4497240
    Abstract: A temperature control device for a vehicle cabin comprises a duct which communicatively connects, at least, inside the vehicle cabin and the external atmosphere; a damper provided within the duct and for shutting off flow of air inside and outside the vehicle cabin; drive means for driving the damper to open and close; a fan to produce the air flow within the duct; a fan motor to actuate and drive the fan; detecting means to detect temperature changes within the vehicle cabin; and a power source separately provided from an ordinary power source and for supplying power to the fan motor. A temperature increase within the vehicle cabin above a predetermined temperature is detected by the detecting means, then electric power is supplied to the fan motor from the separately provided power source, and the temperature within the vehicle cabin is controlled in utilization of the duct, in which the damper is in an open state.

  • Patent number: 4428402
    Abstract: The specification describes a shirred synthetic casing stick closed at one end by first extending an end portion of the shirred stick to form an unshirred end casing portion. The end casing portion is then twisted at a point to form an inner end casing section, and an outer end casing section separated by the twist. The outer end casing section is turned inside out (inverted) to cover at least a part of the inner end casing section and to thereby prevent untwisting. In a preferred embodiment, the end casing portion is twisted at a point indented, from the end of the extended casing portion, 1-2 times the diameter of the stick. The entire end casing portion is preferably inserted within the stick. In another embodiment, the stick is made of regenerated cellulose and an aperture is formed through the twisted closure portion. The specification also describes a method and apparatus for making such an end-closed, shirred synthetic casing stick.
