Since a transmission route is set in accordance with the number of relaying broad band switching nodes present between two terminating nodes of a plurality of broad band switching nodes, a through-put characteristic, an affecting degree due to occurrence of a defect, the traffic of the entire network is distributed. In addition, when the system is started up, transmission routes with a minimum band width necessary for routing control have been set in all the broad band switching nodes. Whenever a call takes place, a transmission route is set and the band width is variably set by using an intelligent inference mechanism. Moreover, an intelligent distributed control for distributing such an intelligent inference mechanism in the broad band switching nodes is used. Thus, the load of processing a call can be decreased, while the reliability of the network and the improvement of the operating efficiency can be achieved. Furthermore, since the private branch system interface uses a frame which consists of a control window area for controlling its transmission and a cell multiplexing area for multiplexingly transmitting cells, bidirectional transmission between the broad band switching node and a plurality of terminal equipments can be achieved with a single extension transmission line. In addition, since a frame construction which satisfies the ATM method is used, different information transmission speeds can be flexibly selected.

A memory has plural storage areas for storing performance data of plural music pieces. When the player has input desired performance data via an input device like a keyboard, the thus-input performance data are automatically stored into a first storage area of the memory. At the same time, a specific search is executed by the search section to examine whether or not performance data of a music piece corresponding to the input performance data are already stored in the memory. If a second storage area storing the performance data corresponding to the input performance data has been detected or searched out, a series of the performance data stored in the second storage area are sequentially read out for an automatic reproductive performance. If, on the other hand, such a second storage area has not been detected, writing of the input performance data into the first storage area is continued without such an automatic reproductive performance being executed. Therefore, it is sufficient for the player to perform an operation to input a part or whole part of the desired music piece. Then, in response to the player's input operation, music piece number selection and readout or write processes are automatically carried out in accordance with the result of the search by the search section.

In order to accomplish the aforementioned and other objects, a resin muffler, according to the invention, is formed of a heat-resistantive synthetic resin having a property of visco-elastic plasticity in a predetermined temperature range. In the visco-elastic temperature range, the motion of the molecular chain segment of the material resin comes to be relaxed to exhibit noise creative pulsating energy dissipation owing to emission as heat energy. Since the resin muffler thus absorbs noise creative energy by dissipation at around the visco-elastic temperature range and transform the energy into the heat energy which may be emitted by radiation.

A high-pressure sodium lamp in which the ends of an arc tube which is made of transparent single-crystal alumina and which contains sodium are sealed with feed-throughs each having an electrode extended from the inner end thereof.Each feed-through is directly sealed to the inner wall surface of each end of the arc tube. In addition, each feed-through is formed with an enlarged-diameter portion which is directly sealed to the inner wall surface at each end of the arc tube and a reduced-diameter portion which is spaced apart from the inner wall surface at each end of the arc tube.

A floor-standing air-conditioning apparatus includes a lower air inlet, an air outlet having an air outlet opening, a heat exchanger that is provided in the body, a crossflow fan that is provided in the body and produces a flow of air in which the air that has flowed into the body passes through the heat exchanger and is guided to the air outlet, a drain pan that is provided below the heat exchanger in the height direction of the body. The heat exchanger includes a front heat exchanger and a rear heat exchanger, a pair of which form a V shape with their lower ends being in contact with, or in proximity to, each other, and are arranged so that the crossflow fan is positioned between the front heat exchanger and the rear heat exchanger.

There has been a problem of dew condensation, during a cooling operation, on a wind vane or the like provided at an air outlet because the wind speed of blown air leaking from ends in longitudinal direction of the air outlet is low, causing the entanglement of room air. Walls that form an air outlet from which air that has exchanged heat in a heat exchanger is blown are provided. End portions of each of the walls in a longitudinal direction of the air outlet have respective recesses such that a passage of the air therein is made wider than in a central portion of the wall. In the longitudinal direction of the air outlet, the recesses each have a downstream-side width that is smaller than an upstream-side width.

A cross flow fan including an impeller having at least two rings arranged with intervals in a fan rotation axis O direction and a plurality of blades that are arranged, between correlated rings, with intervals in a circumferential direction of the rings, in which the blade is divided into plural areas in the fan rotation axis O direction, and both ends adjacent to the rings are denoted as the blade-ring proximate sections and the center portion of the blade is denoted as the inter-blade-ring center section. The blade is formed such that the thickness of the inner peripheral blade end of the blade that is the inner peripheral end of the impeller is smaller in the inter-blade-ring center section than in the blade-ring proximate section.

Disclosed is a cross flow fan that makes uniform a distribution of wind velocity along an axial direction of the fan at an exit of an air trunk and that lessens chance of separation of an air flow on an inlet side of the fan, and there are thereby provided a cross flow fan that accomplishes a lower input and smaller noise and an air blower and an air conditioner that use the cross flow fan. A cross flow fan being rotatably placed in a horizontally-long air trunk, and including a plurality of annular rings that are substantially parallel to each other and a plurality of blades that are radially interposed between adjacent rings, each having a circular arc cross sectional shape, and a camber angle of the blade is smaller at the ring side than at a center area of the blade between the rings in a longitudinal direction.
摘要:
A diesel particulate defuser (DPD) for collecting particulate matter (PM) in exhaust gas is connected to an exhaust pipe of a diesel engine, and when the amount of PM in the DPD becomes equal to or greater than a predetermined amount, the exhaust gas temperature of the diesel engine is increased by performing exhaust pipe injection and DPD is automatically regenerated. In such an exhaust gas purification system, an exhaust gas temperature during DPD regeneration in automatic regeneration is detected, a difference between the detected exhaust gas temperature and a target regeneration temperature is determined, and in a case where an exhaust pipe injection amount is PID controlled based on the difference, when a transition is made from the traveling automatic regeneration to the idle automatic regeneration conducted during a stop, an integral control term in the PID control is reset to zero to control the exhaust pipe injection amount.
