摘要:
A wireless communication system of the present invention includes: terminals; a base station that performs wireless communication with the terminals; a gateway apparatus that manages the terminals and the base station; and a server apparatus that authenticates the terminals. The gateway apparatus includes: at least one C-plane processor that processes C-plane; and N U-plane processors that process U plane. Each of the N U-plane processors notifies the C-plane processor of its own load status. The server apparatus notifies the C-plane processor of service levels of target terminals that try to perform entry to a network in which the base station and the gateway apparatus are located. The C-plane processor allocates, based on the load status of each of the N U-plane processors and the service levels of the target terminals, one of the N U-plane processors as an entry destination to the target terminals.

An exhaust apparatus includes an exhaust pipe passing under the front floor and rear floor and extending toward the rear of the vehicle. A noise eliminator is arranged under the rear floor and a fuel tank is arranged in a side portion in the vehicle width direction of the noise eliminator. A portion of the exhaust pipe on the front side of the front floor and a portion on the rear side of the noise eliminator are elastically mounted to the vehicle body. The exhaust pipe and a portion on the side opposite to the side of the fuel tank at a lower surface portion of the front floor are coupled by a metal wire having slack in an intermediate portion therebetween. In a side impact to the vehicle body, the fuel tank and noise eliminator do not interfere with each other.

In a stacking semiconductor device in which a first-layer and a second-layer semiconductor devices are stacked and bonded with a solder, warpage occurs due to a difference in thermal expansion coefficient of constituent members or a difference in elastic modulus of individual members. Therefore, between the first-layer and the second-layer semiconductor devices are provided an external connection terminal of solder and a thermosetting resin, and the stacking semiconductor device is heated at 150 to 180° C., which are the temperatures of preheating for reflow of the solder, for 30 to 90 seconds. Thereby the warpage of the first-layer semiconductor device is reduced and the thermosetting resin is cured completely in this state. Then, the temperature is raised to a reflow temperature of the solder and solder bonding using the external connection terminal is performed. Thereby, the bonding reliability of a solder-bonded portion of the stacking semiconductor device is considerably improved.

A series of resonators are affixed to a vehicle engine air intake pipe path to provide muffling of air intake noises. An air intake port, facing toward the front of the vehicle, has a midsection bent back on itself. A connection opening is provided on the bent-back part. A pipe-form resonator, having a closed-off tip, is bent back on itself in roughly a U-shape at its midsection. A base end of the resonator is joined to the connection opening of the air intake port. This resonator makes it possible to muffle intake sound of frequencies that heretofore could not be absorbed by other affixed resonators.

A shredded tobacco supplying apparatus for a cigarette manufacturing machine has a supply passage extending toward a conveyor belt, the supply passage is provided with a plurality of air blowing openings arranged at intervals in the direction perpendicular to the longitudinal axis of the conveyor, and a straightening plate having a plurality of straightening fins is mounted at the air blowing opening. The straightening fin extends at a predetermined angle toward the front side of the conveyor with respect-to the axis perpendicular to the longitudinal axis of the conveyor. The air injected from the air blowing opening is blown into the supply passage at a predetermined angle with respect to the aforementioned axis. The shredded tobacco reaching the supply passage is discharged toward the belt surface of conveyor belt by using an air flow produced by the air blown from the air blowing openings. As a result, a velocity component in the belt running direction is given to the shredded tobacco, so that the attracting property of shredded tobacco to the belt surface is enhanced. Thereupon, the reduction in attracting property caused by the increase in belt running speed, and in turn, the degradation in cigarette quality are prevented.

On an annular lib 16 formed at the downstream of an upper cylinder portion 3a of an air-cleaner outlet hose 3, a hose connecting portion 3f is formed to which one end of a resonator 6 is connected, and an intermediate portion 6c of the resonator 6 is fastened at a resonator clamp portion 3h formed in a unit with the upper cylinder portion 3a at the upstream. Further, on the above mentioned annular lib 16 provided adjacent to the bellows portion 3c of the air-cleaner outlet hose 3 a suction air temperature sensor 4 is provided at a position which is not opposing to the position of the resonator, and a harness clamp portion 3e of the suction air temperature sensor 4 is provided. Due to the floating support of the resonator, a reduction of the vibration transmission to the vehicle chamber and the number of the parts and the mounting processes is realized, and eventually a cost down is realized. Further, since the parts are disposed on the annular lib 16, the rigidity of the bellows portions 3c close thereto is increased.
