According to an embodiment, there is provided a heat spreader including a condenser portion formed of a nanomaterial. The heat spreader further includes a first plate member, a second plate member, and a support portion. The first plate member includes a first surface, the first surface including a first area provided with the condenser portion. The second plate member includes a second surface and is arranged such that the second surface faces the first surface. The support portion protrudes from the first area of the first plate member to the second plate member, and has an end portion that is free from the nanomaterial and is in contact with the second surface of the second plate member.

Heat spreader, electronic apparatus, and heat spreader manufacturing method

According to an embodiment, there is provided a heat spreader including an evaporation portion, a first condenser portion, a working fluid, and a first flow path. The evaporation portion is arranged in a first position. The first condenser portion is arranged in a second position, the second position being arranged apart from and higher than the first position. The working fluid evaporates from a liquid phase to a gas phase in the evaporation portion, and condenses from the gas phase to the liquid phase in the first condenser portion. The first flow path is made of a nanomaterial, has hydrophobicity on a surface, and causes the working fluid condensed to the liquid phase in the first condenser portion to flow to the evaporation portion by a gravitational force.

Provided is a vibrating device which can generate efficient vibrations in a vibrating member and efficiently apply vibrations to a gas, a jet flow generating device in which the vibrating device has been implemented, and an electronic device in which the jet flow generating device has been implemented. A jet flow generating devicehas a vibrating deviceincluding a frame, and actuatormounted on the frame, and a vibrating membersupported on the frameby an elastic supporting member. The vibrating memberhas a side plateformed on the perimeter portion of a disc-shaped vibrating plate, for example. Vibration of the vibrating memberapplies vibrations to air within chambersand, whereby gas can alternatingly be blown from nozzlesand

A plate-type heat transport device and electronic instrument are provided. The plate-type heat transport device includes a heat absorbing plane absorbing heat because of the evaporation of a working fluid, a heat emission plane opposing the heat absorbing plane and emitting heat because of the condensation of the working fluid, and a flow path two-dimensionally arranged between the heat absorbing plane and the heat emission plane to align with the heat absorbing plane and the heat emission plane, the flow path allowing the working fluid to flow therethrough for changing the phase of the working fluid, and the flow path being capable of two-dimensionally diffusing the working fluid by generating a capillary force in the condensed working fluid.

Plate-type heat transport device and electronic instrument

A head slider for a flexible magnetic disk has a magnetic pole pad including a magnetic head buried in the pad and being disposed on a surface of the head slider opposed to the flexible magnetic disk, and the magnetic head performs the recording of a signal on the flexible magnetic disk or the reproducing of the signal from the flexible magnetic disk in a state that the pad contacts the flexible magnetic disk rotating at a relative speed of 0 m/s to 25.0 m/s to the magnetic head.
