Abstract: An aluminum-copper clad member includes an aluminum-base member, a copper-base member and an insertion member made of pure aluminum or JIS A1xxx series aluminum alloy. The aluminum-base member and the copper-base member are clad via the insertion member. A heat sink includes a heat radiation portion made of aluminum-base material and provided with a plurality of tongue-like fins formed by skiving a surface layer of one side of the heat radiation portion and a thermal diffusion portion made of copper-base material and joined to the other side of the heat radiation portion via an insertion member made of pure aluminum or JIS A1xxx series aluminum alloy.

Abstract: The present invention relates to an electric food preparation apparatus such as a food processor, juicer or the like. An annular cavity is formed in the fitting portion between the container body and the container lid. The annular cavity is communicated with the interior of the container body through communication passages. Fluid guiding members are disposed at the upstream side of respective communication passages to generate negative pressure in the respective communication passages. The liquid leaking outside is induced back into the container body through the communication passages so that external leaking of the liquid is prevented.

Abstract: For use in a food processor comprising a power unit having a drive shaft, a removable receptacle including a container and a lid having a feed chute communicable to the interior of the receptacle when mounted on the container, and a rotary treating element rotatable within the receptacle together with the drive shaft, a tilt preventing element for preventing a food material inserted into the feed chute from being tilted sideways which comprises an elastic retainer member including a plurality of long elastic tines and a corresponding number of short elastic tines. The long and short tines are curved so that, when the elastic retainer member is removably mounted on the open end of the feed chute opposite to the container, they extend downwardly in the feed chute and diverge outwardly from the surrounding wall defining the feed chute.
