Patent number: 5382712Abstract: High quality bisphenol A is produced from a neutral crystalline adduct of bisphenol A and phenol by fusing the adduct in an atmosphere having a maximum oxygen content of 0.005% by volume, followed by evaporation of liberated phenol. The crystalline adduct may be mixed with an aliphatic carboxylic acid before the fusion to reduce the coloring of the product. When an acidic crystalline adduct is used, the use of a strong alkali salt of an aliphatic carboxylic acid is suitably used. Interior surfaces of the apparatuses for carrying out the fusion and evaporation are desirably washed with an organic solvent to remove oxygen therefrom. The evaporation of phenol is suitably performed by two stage steam stripping wherein a used stripping gas obtained in the second stage is employed as a stripping gas in the first stage while steam is used as the stripping gas in the second stage.Type: GrantFiled: April 18, 1994Date of Patent: January 17, 1995Assignee: Chiyoda CorporationInventors: Sachio Asaoka, Tetsuo Maejima, Kouji Sakashita, Noriyuki Yoneda, Makoto Yasui, Nobuhiro Onda, Tsuneo Watanabe, Nobuo Moriya, Akio Shindo, Hiroaki Nishijima, Athumi Kukidome, Ryuichi Inaba, Takashi Imazeki, Kaoru Shimogawara

Patent number: 5355301Abstract: To improve high frequency characteristics of a transformer in a switching power supply device and to reduce its size, the switching power supply device is formed of a voltage converting section in a thin-film laminated structure, a single semiconductor chip and a wiring layer situated between the voltage converting section and the single semiconductor chip. All the active elements including switching elements and voltage controlling sections are incorporated into the semiconductor chip and are connected to the voltage converting section through the wiring layer. To reduce the effects other than inductance of the electrical components, a thin film transformer is formed of a spiral-shaped primary coil and secondary coil formed on a substrate. The primary and secondary coils are arranged so that phases of forming cycles in the radial direction are different to have a staggered relation. Accordingly, the capacity of the parasitic capacitors between the primary coil and the secondary coil is very small.Type: GrantFiled: March 1, 1993Date of Patent: October 11, 1994Assignee: Fuji Electric Co., Ltd.Inventors: Akira Saito, Yasurou Motoi, Tsuneo Watanabe
