摘要:
Graphite particles having a bent laminate structure inside each particle are produced by feeding, into an impact grinder, graphite particles having an average particle diameter of 5 mm or less together with a gas current to apply an impact to the graphite particles to form, by a compression force, a bent laminate structure inside each graphite particle. The resulting graphite particles have an average particle diameter of 100 μm or less, are low in anisotropy, have a nearly spherical shape, and are highly crystalline.

摘要:
A communication apparatus is configured to include first and second cards, and a card-to-card link connecting the cards. Each card is communicably connected to another communication apparatus through a route connected to the card. One of the cards is determined to be a primary card that controls data transmission between the communication apparatus and another communication apparatus, and the other card is determined to be a secondary card controlled by the primary card. The primary card establishes a primary data-path for transmitting primary data, using one of the first and second routes connected to the primary card. The primary card further establishes a secondary data-path for transmitting secondary data, using the card-to-card link, the secondary card, and the other one of the first and second routes connected to the secondary card.
摘要:
The cellular telephone device includes a control unit that executes any one of a plurality of applications, and a storage unit that stores an execution count of an application executed by the execution unit. The control unit determines an application to be executed after terminating or suspending a predetermined application, based on the execution count stored in the storage unit.
摘要:
An electronic component mounting configuration in which an electronic component chip having a plurality of protrusion-shaped electrodes distributed on its entire mounting surface is mounted through protrusion-shaped electrodes on a printed circuit board is provided which is capable of improving reliability of an electronic component by relieving thermal stress. The solder bumps are arranged so that intervals between solder bumps adjacent to one another become smaller from a central portion of a mounting surface of the electronic component chip toward the peripheral portion thereof. For example, an interval between the solder bump “1A” arranged in the central portion of the semiconductor chip and the solder bump “1B” arranged in an outer side thereof, adjacent to each other, is set to a pitch of P1. An interval between the solder bump “1B” and the solder bump “1C” formed arranged in an outer side thereof, adjacent to each other, is set to a pitch of P2 and an interval between the solder bump “1C” and the solder bump “1D” formed arranged in an outer side thereof, adjacent to each other, is set to a pitch of P3 (P1>P2>P3).
