Patent number: 8958907Abstract: A robot arm apparatus includes an arm mechanism including a base member and a link pivotally connected to the base member for pivotal motion in a horizontal plane through a rotational shaft. The link holds a regular circular transport object at its distal end.

Patent number: 4061650Abstract: Alkyl (or aralkyl) .alpha.-isocyanoacetate is condensed with a trihalogenoacetic aldehyde or its hydrate in the presence of an amine to give trans-4-alkoxycarbonyl(or aralkyloxycarbonyl)-5-trihalogenomethyl-2-oxazoline. The oxazoline compound is hydrolyzed under acidic conditions to give threo-.gamma.,.gamma.,.gamma.-trihalogenothreonine, which is then subjected to catalytic or electrolytic reduction. The above-mentioned reactions can be carried out stereoselectively and threo-threonine is thereby obtained without by-products such as allo-threonine.Type: GrantFiled: November 26, 1975Date of Patent: December 6, 1977Assignee: Tanabe Seiyaku Co., Ltd.Inventors: Munetsugu Miyoshi, Kazuo Matsumoto, Yuji Urabe, Tameo Iwasaki
