Title: Novel poly(oxyalkylene)amide-amine gasoline additives
Inventor: LIN JIANG-JEN
IPC: C10L1/12
Filed: 2000-08-19
Granted: 2002-11-01
Abstract: The present invention is one kind of gasoline additives. The compounds consist of tertiary amine, amide and poly(oxybutylene) backbone in the same molecule. The process of making this type of products required an initiator containing primary amine and tertiary amine as the starting diamines. The primary amine will be converted into amide, while the tertiary amine remained intact. Then the amide is converted into butoxylates through butoxylation at CON-H position. The preparation therefore involved two steps: (1) amidation of diamines containing primary/tertiary amines with ethyl acetate to form amidoamines, and (2) butoxylation of this amidoamines to poly(oxybutylene)amidoamine. The product is gasoline soluble and can be used as additive having good performance of detergency and octane requirement reduction.

Title: Nitride semiconductor device and its manufacturing method
Inventor: KOBAYASHI TOSHIMASA
IPC: H01L33/02
Filed: 2002-03-21
Granted: 2003-07-11
Abstract: Provided is a nitride semiconductor device with high reliability and high flexibility in design and manufacture of the device. The nitride semiconductor device comprises a seed crystal portion 11 formed on a sapphire substrate 10 and having an insulation layer 12 on one side surface thereof, and a GaN layer 15 grown on the sapphire substrate and the seed crystal portion through epitaxial lateral over growth. The GaN layer is grown only from an exposed side surface of the seed crystal portion 11 which is not covered with the insulation layer, so the lateral growth of the GaN layer is asymmetrically carried out. Thereby, a meeting portion 32 is formed in vicinity of a boundary between the seed crystal portion and the insulation layer in a thickness direction of GaN layer. Therefore, compared to the structure of the prior art in which the meeting portion is formed at the center of each seed crystal layer, the meeting portion of the embodiment of the present invention exists in the vicinity of the boundary between the seed crystal layer and the insulation layer. Thus, when the width in the low defect-density region is WL, the spacing in the seed crystal layer is Wp and the width of the seed crystal layer is Wo, since Wp is approximately equal to Wo+WL, and WL > Wo, thereby they satisfy the relation: WL > 0.5xWp so as to obtain a WL which is larger compared with that of the conventional configurations.
