Abstract: Provided is an interference control system for wireless communication suitable for limiting the total amount of interference to which an interfered-with wireless communicator to be protected is subjected by interfering wireless communicators. A repeater disposed between the interfering wireless communicator and a controller includes a processor and a memory storing a program executed by the processor. The processor acquires registration information including a position and a transmission power for each interfering wireless communicator, and estimates, for each interfering wireless communicator, a terminal range in which there is a likelihood that a terminal wireless communicator communicating with the interfering wireless communicator is present based on the position and the transmission power. The processor transmits a registration application including the terminal range to the control device.

Abstract: Provided is an interference control system for wireless communication suitable for limiting the total amount of interference given to an interfered device to be protected by a large number of interfering devices. The system provides a control device disposed in a public network with a resource application based on a message issued regarding use of a radio resource by an interfering device disposed in a carrier network. A response based on a message issued by the control device with respect to the resource application is provided to the interfering device that has issued the resource application. A resource table including information in which availability of frequency in carrier network is estimated is updated on the basis of the resource application and the response. The information in which the availability is estimated and included in the resource table is reflected in the resource application.

Abstract: Provided is an interference control system for wireless communication suitable for limiting the total amount of interference given to an interfered device to be protected by a large number of interfering devices. An interference control system includes a subscriber database that stores information regarding a position of each interfering device. A registration application (5) including an ID of an interfering device disposed in a carrier network is received from the interfering device. The registration application is received and position information that matches information stored in the subscriber database regarding the ID is set (2), (3), and (6). The position information is transmitted to the control device for registration (6).

Abstract: A rotary compressor is comprised of a first housing having an intake chamber for receiving therein a fluid of variable pressure, and a second housing having an inner peripheral surface to define a working chamber and an inlet communicating between the working and intake chambers. A rotor is rotatably mounted in the working chamber and has a vane slidably supported in the rotor to maintain contact with the inner peripheral surface of the second housing during the rotation of the rotor to thereby compress the fluid flowing into the working chamber through the inlet. A rotary valve is rotatably disposed between the intake chamber and working chamber for regulating the flow rate of the fluid flowing through the inlet in response to angular displacement of the rotary valve. A piston is slidably disposed in a cylinder provided in the first housing.

Abstract: A gas compressor of the variable volume type having a rotary plate which is rotated to move recesses therein communicating with a compression chamber of a cylinder relative to communication ports formed in a front side block fixed to the one side of the cylinder so that the volume of the compression chamber may be made variable in accordance with the fast or slow running state of the gas compressor. The rotary plate is moved rotatably by means of a self-contained and self-actuated hydraulic cylinder which is driven by oil within the compressor in response to the intake pressure of the compressor's intake chamber.

Abstract: A variable-capacity gas compressor comprising a cylinder front and rear side blocks attached to both ends of the cylinder, a control plate formed with a recess or suction port which communicates with a communication port in the front side block and thereby forms a path for gas to flow into a cylinder chamber. The control plate is secured to the inner side of the front side block so that it may rotate within a given angular range. A driving means for driving the control plate and a control mechanism for controlling the driving means are provided so that the gas comnpressor is able to increase the cooling efficiency in the passenger compartment of an automobile in the beginning period of operation and to subsequently prevent any excessive cooling during continuous operation.
