    Abstract: A communication apparatus which performs data communication by bundling multiple bands. The communication apparatus includes a communication section that performs transmission and reception of a wireless signal by using multiple bands, and a control section that controls communication operation of the communication section. The control section performs control such that, after a transmission right has been acquired in a first band, a first signal is transmitted in the first band before a transmission right is acquired in a second band. The control section also performs control such that, when the transmission rights are acquired in both the first band and the second band, data transmission is performed by using the first band and the second band simultaneously. An RTS frame, a CTS frame, a data frame, a busy tone, or the like is transmitted as the first signal.

  • Patent number: 8143992
    Abstract: A multilayer chip varistor is provided as one capable of suppressing production of cracks and thereby preventing a connection failure between an internal electrode and a through-hole conductor. An internal electrode 21 is so configured as to be curved toward a direction of penetration of a through hole 10 in a connection portion 28 thereof to a through-hole conductor 27. By this configuration, a region T sandwiched between a curved surface 28a of the connection portion 28 and the through-hole conductor 27 is formed in a varistor layer 9 near the connection portion 28. In this region T, a metal concentration thereof becomes higher because of diffusion of metal of the internal electrode 21 and the through-hole conductor 27 into the varistor layer 9, and therefore, after completion of firing, the region T has an intermediate contraction percentage between that of the internal electrode 21 and through-hole conductor 27 and that of the other region of the varistor layer 9.

  • Patent number: 7994894
    Abstract: A varistor having a favorable heat-dissipating property is provided. In the varistor, a composite part having a favorable heat-dissipating property formed by a composite material composed of ZnO and Ag is arranged between main faces of a varistor matrix. Therefore, the heat transmitted from a semiconductor light-emitting device to a varistor part through an outer electrode can rapidly be transferred toward a main face on the opposite side through the composite part. In this varistor, side faces excluding inner side faces are exposed at side faces of the varistor matrix. Such a structure yields a favorable heat-dissipating property.

  • Patent number: 7932806
    Abstract: In a varistor, a heat radiating portion contains the same components as ZnO that is the main component of a varistor element body, as metal oxides, thereby, the structural components of the varistor element body and the heat radiating portion are caused to be common. During firing, Ag contained in the heat radiating portion diffuses into the grain boundaries of ZnO, near the interface between surfaces of the heat radiating portion and the varistor element body. Consequently, in the varistor, cracks hardly occur between the varistor portion and the heat radiating portion during firing (or during binder removal), thereby, ensuring sufficient bonding strength between the varistor portion and the heat radiating portion. Therefore, heat conducted to the varistor portion is radiated efficiently conducting through electrically conducted paths formed in the heat radiating portion from the surface facing the varistor element body to other three surfaces of the heat radiating portion.

  • Patent number: 7911317
    Abstract: A multilayer chip varistor is provided as one having excellent heat radiation performance. A thickness between a first principal face 3 and an outermost internal electrode layer 11A is smaller than a thickness between an internal electrode layer 21 and the outermost internal electrode layer 11A, and because of this configuration, heat generated from a bottom face of a semiconductor light emitting device LE1 is efficiently transferred to the outermost internal electrode layer 11A having a high thermal conductivity. Furthermore, in the multilayer chip varistor V1 of an electronic component EC1, the outermost internal electrode layer 11A has a first internal electrode 13 electrically connected to a first connection electrode 7 and a first terminal electrode 5 through first through-hole conductors 17, and a second internal electrode 15 electrically connected to a second connection electrode 8 and a second terminal electrode 6 through second through-hole conductors 27.
