摘要:
Charging apparatus 10 includes secondary battery 13 used for buffering, rectifier 11 that supplies direct current power to secondary battery 13 used for buffering, DC-DC converter 14 connected to driving battery 3 in electric vehicle 2 via charging cable 4, switching control circuit 12, and isothermal wind generator 16 that adjusts the temperature of secondary battery 13 used for buffering from outside of secondary battery 13 used for buffering. Switching control circuit 12 switches charging apparatus 10 between a first mode in which power supplied by rectifier 11 is accumulated in secondary battery 13 used for buffering and a second mode in which driving battery 3 is charged with the power supplied by secondary battery 13 used for buffering. Secondary battery 13 used for buffering includes at least one cell in which a battery element with a positive electrode plate and a negative electrode plate that are laminated therein is sealed with an outer cover film.
摘要:
In a semiconductor package stack module, an LSI (Large Scale Integrated circuit) is mounted, via fine bumps, on a ceramic carrier substrate or a flexible carrier film on which wiring conductors are formed. After a seal resin has been injected, the chip is thinned by, e.g., grinding. A plurality of such carrier substrates or carrier films are connected to each other by bumps via through holes which are electrically connected to the wiring conductors, thereby completing a tridimensional stack module. The module achieves a miniature, thin, dense, low cost, and reliable structure without resorting to a wire bonding system or a TAB (Tape Automated Bonding) system. In addition, the module has a minimum of wiring length and a desirable electric characteristic.

An integrated circuit connecting method that includes connecting electrode pads on an integrated circuit device to electrode terminals on a base with metal bumps interposed, the electrode terminals being formed in registry with the electrode pads. The method includes the steps of forming metal bumps on a surface of at least one of the electrode pads and the electrode terminals; covering the surface on at least one of the integrated circuit device side and the base side with a resin that cures upon exposure to active energy rays; patterning the resin to strip selectively the coating of the resin over one of the electrode pads and the electrode terminals; bringing the electrode pads and the electrode terminals into a face-to-face relationship, allowing the metal bumps to contact one of the opposing electrode pads and electrode terminals, performing thermocompressing so that the resin coating will adhere closely to one of the integrated circuit device and the base while, at the same time, the electrode pads are connected to the electrode terminals with the metal bumps interposed; and performing at least one of heat treatment and exposure to active energy rays.

The improved dielectric ceramic composition has sufficiently high dielectric constant, high insulation resistance and small dielectric loss to be suitable for use as a material for ceramic capacitors. The composition comprises as a main component a three-component ceramic composition in solid solution having the formula Pb(Mg.sub.1/3 Nb.sub.2/3)O.sub.3 -Pb(Ni.sub.1/3 Nb.sub.2/3)O.sub.3 -PbTiO.sub.3 which, when expressed by xPb(Mg.sub.1/3 Nb.sub.2/3)O.sub.3 -yPb(Ni.sub.1/3 Nb.sub.2/3)O.sub.3 -zPbTiO.sub.3, is defined by the area surrounded by the following points of (x, y, z), i.e., (0.70, 0.20, 0.10), (0.70, 0.15, 0.15), (0.83, 0.02, 0.15), (0.96, 0.02, 0.02) and (0.78, 0.20, 0.02), and this ceramic composition further contains a Mn oxide or a Mn-containing complex oxide as an additive.

Aluminum nitride ceramics is prepared by mixing acetylide of calcium, strontium, barium or other material with raw aluminum nitride powder with a content between 0.02 and 10 wt %, forming the mixture into a predetermined shape and sintering the formed body in a non-oxidizing atmosphere such as nitrogen gas by pressureless and/or pressure sintering technique.
摘要:
A ceramic dielectric material according to the present invention has a composition consisting essentially of La.sub.2 Ti.sub.2 O.sub.7, Sr.sub.2 Nb.sub.2 O.sub.7, and 1/2Mg.sub.2x --Ti.sub.2.sub.-2x O.sub.4.sub.-2x, where x lies in a range of 0 to 1.0. This material has a relatively large dielectric constant, a very stable temperature coefficient of the dielectric constant over a wide temperature range, a widely controllable value of the temperature coefficient of the dielectric constant, and a small dielectric loss. The temperature coefficient of the dielectric constant can be determined optionally in a wide range of value by simply changing the ratios among the three constituents of the composition.
