Abstract: The present invention provides a heat sink having improved heat-exchange. A heat sink (10) which transfers heat dissipated from a heat generating device (12) to a cooling fluid (CF), said heat sink comprises: a planar base plate portion (11) that is thermally connected to the heat generating device (12); and a fin unit (10A) having a plurality of louvers (13) and a frame portion (14) that connects to the plurality of louvers and surrounds thereof. One edge of said plurality of louvers is thermally connected to the base plate portion; and said frame portion is situated apart from a principal surface of said base plate portion.

Abstract: A heat sink (1), has heat pipes (3) which are disposed in a high temperature section (A) of a base plate (2) on which a heating element (4) is disposed so that the heat pipes (3) extend from the high temperature section (A) to low temperature sections (B) in different directions.

Abstract: An Al—Mg-based aluminum alloy pipe for hot working, having an alloy composition having from 2.5% by mass to 2.8% by mass of Mg, 0.25% by mass or less of Si, 0.35% by mass or less of Fe, and from 0.25% by mass to 0.35% by mass of Cr, with the balance being inevitable impurities and Al, wherein an area ratio of cavities after hot working is 2.3% or less; and an aluminum alloy structural member for automobile using the same.

Abstract: An aluminum alloy energy-absorbing member, which satisfies the conditions of &agr;≧24 and (&agr;×&sgr;)≧6000, wherein &agr; (%) is the rupture elongation at a gauge distance of 5 mm, and &sgr; (MPa) is a 0.2% proof stress value, in the extruding direction of an aluminum alloy extruded material. This is an aluminum alloy energy-absorbing member that is lightweight, high in energy absorption, adequate in required mechanical strength, and preferable as an impact-absorbing member for an automobile, and the like.

Abstract: A facsimile apparatus comprises an image scanner and a coder for image transmission, a decoder and a printer for image reception, and a modem and a network control unit for connection with a subscriber's line. These elements are connected to a control unit for controlling the entire apparatus. The presence/absence of printing paper is detected by a sensor. When the printing paper is absent, received image data is not supplied to the printer and instead is written in an image memory for performing a so-called substitute reception. The facsimile apparatus further comprises a dial number memory for storing a dial number of a predetermined facsimile apparatus, and a dialer for automatically dialing the dial number stored in the dial number memory. When the substitute reception is completed, the dial number stored in the dial number memory is dialed, and the image data stored in the image memory by the substitute reception is transferred to the predetermined facsimile apparatus and is printed.

Abstract: A facsimile communication method wherein a facsimile transmitter transmits a portion of the message data to a facsimile receiver as the training check signal. A modem in the receiver trains automatically by its equalization function. The training is verified by ensuring that a predetermined number of bits per line have been transmitted and received. In case of success in training, the rest of message data is then transmitted.
