IPC: C08J3/22
Filed: 2003-05-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for kneading a fine carbon fiber into a specific resin.  <P>SOLUTION: This method for manufacturing a high dispersion resin mixture comprising an elastomer, a thermoplastic resin or a thermosetting resin is to mix the elastomer and the thermoplastic resin or the thermosetting resin with a fine carbon fiber of a nano scale without bringing about a chemical reaction. The elastomer shows a Williams plasticity of 80 to 400; the thermoplastic resin shows a melt index (MI) of 2 to 40 g/10 min., preferably 3 to 40 g/10 min.; and the thermosetting resin shows a viscosity of 0.6 to 2,000 Pa×s. This method comprises a process to form a parcel by enveloping the fine carbon fiber with the resin as a wrapping film and a multi-layer rolling process to fold and again roll a plate-like body obtained by rolling the parcel and does not require an additional material for kneading as an indispensable material.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: H01L23/373
Filed: 2003-05-23
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the manufacturing cost of a semiconductor device for amplification used for an power amplifier for base station.  <P>SOLUTION: A heat sink 1A working as a mounting base of an amplifier 20 is made of Cu-Mo alloy or Cu-W alloy metallic material whose coefficient of thermal expansion is approximate to that of a silicon (Si) because a first area (La) to which a transistor 2 for amplification is connected is exposed at a high temperature, and no large thermal stress is applied to a joint part with the transistor 2 as a result. In addition, a second area (Lb) surrounding the first area (La) is made of Cu that can be obtained at a lower cost than the Cu-Mo alloy or Cu-W alloy. Since the second area (Lb) is located away from a position where the transistor 2 generating a large amount of heat is connected, no large thermal stress is applied to the joint part with the transistor 2 even if the second area (Lb) is made of Cu having a large difference of the coefficient of thermal expansion from silicon (Si).  <P>COPYRIGHT: (C)2005,JPO&NCIPI
