摘要:
A heat sink includes a heat receiving part for receiving heat from the outside, a first radiating part, connected to said heat receiving part, which forms a first air channel, and radiates the heat from said heat receiving part using air that passes through the first air channel, and a second radiating part, located apart from said heat receiving part and connected to said first radiating part, said second radiating part forming a second air channel which the air that has passed the first air channel enters, the second air channel being narrower than the first air channel, said second radiating part radiating the heat from said first radiating part.
摘要:
The present invention relates to a heat dissipation structure for a notebook type computer, capable of effectively dissipating heat generated from a high temperature element (such as a CPU). The heat dissipation structure comprises a main body, a display device and a hinge shaft for coupling the main body with the display device, wherein the hinge shaft is arranged above the main body at a distance therefrom, and a heat dissipation means is provided in the main body.

A position detecting apparatus detects the position of an object and includes a sensor device which outputs first and second AC detection signals which have a predetermined phase relationship and which correspond to a detected position of the object. An instantaneous value detecting unit detects and outputs instantaneous values of the first and second AC detection signals. A DC component detecting unit processes the instantaneous values to obtain first and second DC components of the first and second AC detection signals, respectively. A position calculating section calculates the position of the object based on a difference between the first DC component and the first AC detection signal, and a difference between the second DC component and the second AC detection signal.

Provided is a system whose effective endurable number of rewrite times can be drastically improved in a storage device using a flash memory whose rewrite life is restricted. The logical address (LBA) of a sector in which data which is not used as a file system is accumulated is detected. Mapping information on a physical address (PBA) corresponding to the logical address is released. A block in which the mapping information on every logical address and physical address is released out of blocks of the flash memory is deleted and used as an alternative block for wear leveling.

A heat sink for a semiconductor device comprises a base which has a first surface on which a plurality of heat-radiating fins are arranged, and a second surface which contacts the semiconductor device directly. A heat spreader is provided on the second surface of the base so that the heat spreader does not contact the semiconductor device directly.
摘要:
A tire (2) includes a belt (12) provided on a carcass (10) and a band (14) for covering the belt (12). The band (14) includes a full band (36) and a pair of edge bands (38) provided in the vicinity of a shoulder and positioned on an outside in a radial direction of the full band (36). The full band (36) has a first band cord (40) wound spirally in a substantially circumferential direction. The edge band (38) has a second band cord (44) wound spirally in the substantially circumferential direction. A modulus of the second band cord (44) is higher than that of the first band cord (40). In the tire (2), it is preferable that an outer end (50) of the full band (36) should be provided on an outside of an outer end (48) of the belt (12) in an axial direction. An outer end (52) of the edge band (38) is identical to the outer end (48) of the belt (12) or is provided on an inside thereof.
