摘要:
In a mobile communication system of the present invention, a cordless base unit LBU is connected to a wired subscriber line SL. The base unit LBU detects a radio channel assigned to a cell other than a cell where the base unit LBU is located, among radio channels assigned to the cells of a cellular radio communication system. This radio channel is used as a radio channel for a cordless call. On the other hand, a cellular cordless telephone CCT is provided with a mode switch. When a cordless mode is designated by the mode switch, a radio channel for a cordless call is detected, as with the case of the base unit LBU. At the time of the cordless call, a transmission power level of the cellular cordless telephone CCT is set at a weak level smaller than that for a cellular call.

To be able to control minute flow in a heat exchanger flow control valve without requiring a minute opening portion, an opening surface area of a hot-water inlet pipe into which hot water flows from an engine is restricted by a first restricting portion of a control passage provided in a needle valve of a flow control valve, and along with this, an opening surface area of a hot-water outlet pipe connected to an inlet side of a heat exchanger for heater use is restricted by a second restricting portion of a control passage formed in the needle valve, and a middle portion of these two control passages is constantly connected to a bypass circuit by a third restricting portion. Pressure of the middle portion thereof can thereby be lowered, pressure applied to the heat exchanger can be adequately reduced, and for this reason minute flow through the valve can be controlled even without establishing a minute opening portion using the needle valves Also, change in heat-exchanger hot-water flow can be reduced by structuring the first and second restricting portions in a configuration whereby flow constant is reduced as amount of flow increases and, along with this, structuring the third restricting portion in a configuration whereby flow constant is maintained substantially uniformly even if amount of flow increases.

A compressor has a compression chamber and a discharge region. The discharge region receives the compressed gas discharged from the compression chamber. A relief valve is mounted to inside of the wall in the discharge region. The relief valve connects the discharge region with the exterior of the compressor so as to discharge the excessively raised pressure in the discharge region.

A piston-reciprocating type compressor has a disk mounted on a rotary drive shaft and operably coupled to a piston. The piston compresses refrigerant gas in a cylinder bore with a compressive force according a cooling load. A retaining chamber formed in the vicinity of an end of the drive shaft. A partition is housed in the retaining chamber. Two recesses are formed with the opposite sides of the partition in the moveable manner. The compressed gas is supplied to the recesses under pressure in proportion to the cooling load. A thrust bearing which connects with the partition supports an end of the drive shaft. The drive that is biased in the direction counter to a thrust load acting on the drive shaft.

A radio communication apparatus includes a base unit connected to wired lines and a plurality of radio telephone sets connected to the base unit via a radio link, and can inform an operator using each individual radio telephone set of service states of the wired lines without a special operation. Wired-line information indicative of the service states of the wired lines is transmitted with such wired-line information contained in a control signal which is transmitted from the base unit to the radio telephone sets when the base unit is to establish a radio link with the radio telephone sets or at the time of the termination of establishing the radio link. The radio telephone sets receives information indicative of the service states of the wired lines from the base unit, and displays the service states of the wired lines on a display device on the basis of such information.
摘要:
A swash plate type refrigerant compressor having an axial cylinder block assembly having therein a double-headed piston operated compressing mechanism for compressing refrigerant gas introduced from an external air-conditioning system to a plurality of cylinder bores, the compressor further having a swash plate chamber capable of not only permitting a swash plate to rotate to thereby reciprocating the pistons but also receiving the refrigerant gas before compression, a rotary valve capable of controlling distribution of the refrigerant gas from the swash plate chamber to each of the cylinder bores, and a pair of taper roller bearings mounted in front and rear housings attached to the cylinder block assembly, and rotatably and stably supporting a drive shaft for mounting thereon the swash plate. The front and rear housings having only a discharge chamber for receiving the compressed refrigerant gas, respectively.

A cordless telephone system in which a battery of a mobile unit can be charged with use of a cordless charger. The charger, which is provided separately from a base unit, has a chargeable battery which is larger in current capacity than the battery within the mobile unit. When the mobile unit is mounted on the charger, the battery of the mobile unit is charged with the battery of the charger. So long as the charge level of the battery within the charger is sufficiently high, the battery of the mobile unit is charged with the battery of the charger and without use of a commercial AC power source.
摘要:
In a radio communication system which comprises a plurality of base units and at least one radio mobile terminal, for the purpose of connecting an incoming signal to the radio mobile terminal through a suitable one of the plurality of base units, there is provided a memory for storing schedule data containing data of radio zones of the base units where the radio mobile terminal is to be located and time periods during which the radio mobile terminal is to be located in the radio zones so that, when an incoming signal is transmitted from a wired communication system, one of the base units to be used for the connection of the incoming signal is selected on the basis of the schedule data stored in the memory to execute the connection of the incoming signal to the radio mobile terminal.

A radio communication apparatus used generally indoors and including a base unit connected to at least one wired line and a plurality of mobile units connected to the base unit through respective radio communication channels. Each mobile unit is able to know the status of use--busy, hold or idle--of the wired lines. Each mobile unit makes to the base unit a request for information on the status of use of the wired line. The base unit sends to the mobile unit the information on the status of use of the wired line in response to the request, which status is displayed in the respective mobile units.
