Patent number: 6258575Abstract: An oil or fat phase is provided above an aqueous phase in a substrate-feeding chamber such that there is a distinct interface between the phases. The phases are separately removed from the chamber, mixed together and fed to an immobilized-enzyme reaction column to produce a reaction mixture. The mixture is fed to the substrate-feeding chamber and introduced into the oil or fat phase such that the interface remains distinct and undisturbed, and monoglycerides, diglycerides and fatty acids remain in the oil or fat phase and water and glycerol separate into the aqueous phase. Steps of the process are repeated while maintaining the interface distinct and undisturbed in the substrate-feeding chamber until a desired degree of oil or fat hydrolysis is obtained. The mixture from the reaction column may be fed to a mixing chamber, mixed with water from the substrate-feeding chamber, and fed to the substrate-feeding chamber.Type: GrantFiled: November 24, 1999Date of Patent: July 10, 2001Assignee: Kao CorporationInventors: Masami Shimizu, Toshiteru Komatsu, Naoto Yamada

Patent number: 6201777Abstract: An apparatus for discriminating optical disks has an optical pickup provided with an objective lens having an effective numerical aperture of 0.55 to 0.65, which can compatibly reproduce information from a CD and an SD. The apparatus discriminates presence/absence of waveforms of two focus error signals detected when the effective numerical aperture of the objective lens is set at 0.55 to 0.65 and 0.20 to 0.45 respectively in a process of performing focus servo control, thereby discriminating various types of optical disks from each other. Thus, optical disks having different substrate thicknesses, different track pitches, different minimum pit lengths and different reflectivity can be quickly and simply discriminated from each other.Type: GrantFiled: February 17, 1999Date of Patent: March 13, 2001Assignee: Sanyo Electric Co., Ltd.Inventors: Yoichi Tsuchiya, Seiji Kajiyama, Yasuyuki Kanou, Shuichi Ichiura, Koichi Tada, Masami Shimizu, Toshio Harada
