Title: Purifying method for polylactic acid-polyethylene glycol-polyactic acid triblock copolymer
Inventor: SAKURAI KAZURO
IPC: B01J13/04
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a purifying method whereby a crude polylactic acid- polyethylene glycol-polylactic acid triblock copolymer is purified into a triblock copolymer which has a narrow mol.wt. distribution and a narrow distribution of compsn. ratio and does not contain residual low-molecular components such as an unreacted monomer or an oligomer by using a specific fractional precipitation method. SOLUTION: A triblock copolymer of an ABA type (wherein A is a polylactic acid block formed from L-lactic acid and/or D-lactic acid; and B is a polyethylene glycol block) is produced by polymerizing lactide at its m.p. or higher in the presence of polyethylene glycol and a catalyst. The polymn. may be soln. polymn. in chloroform, though mass production by melt polymn. is industrially adopted. The mol.wt. of the copolymer is adjusted to 100-100,000 depending on the application. A crude triblock copolymer produced as above is purified by repeating fractional precipitation wherein a poor alcohol solvent capable of dissolving either polylactic acid or polyethylene glycol is added dropwise as the precipitant to a soln. of the triblock copolymer in a good solvent and the resultant precipitate is removed from the system.

Abstract: PURPOSE:To allow cancellation of a primary beat by subjecting a low-pass converted carrier color signal to a phase adjustment by a phase adjusting means, adding this signal to a brightness signal, subjecting this brightness signal to a frequency modulation, adding and synthesizing the signal to and with the above-mentioned carrier color signal and multiplex recording the signals in the same track. CONSTITUTION:The low-pass converted chroma signal outputted by a low-pass filter 24 is supplied via an amplifier 31 to a phase correcting circuit 32 which adds the low-pass converted chroma signal subjected to the phase correction to an adder 3. The low-pass converted chroma signal is added to the brightness signal supplied from a brightness/chroma separating circuit 2 by this adder 3. This brightness signal is supplied to a brightness signal processing circuit after a clamp circuit 4. The brightness signal added with the low-pass converted chroma signal is FM modulated by an FM modulation circuit 7 and the FM modulated signal is added to the low-pass converted chroma signal by an adder 9. The signals are then recorded on a information tape 12. The primary beat generated by the secondary distortion in a recording amplifier 10 is removed in this way.

Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To prevent a surface from being damaged even if the lacquered surface is scrubbed clean and polished by cutting the silk flannel in an adequate size and tailoring the hem with a silk thread. SOLUTION: A dustcloth is tailored by cutting the silk flannel finished by weaving, shrinking and napping the silk thread in an adequate size and hemstitching the hem with the silk thread.

Title: Semiconductor device and manufacture thereof
Inventor: OSAKI AKIHIKO
IPC: H01L21/768
Filed: 1989-12-28
Abstract: PURPOSE:To make a metal wiring layer distant from a semiconductor board so as to restrain a mutual diffusion from taking place between them and to obtain a semiconductor device free of a junction leakage by a method wherein a base layer of specific material is formed on a barrier metal layer on the base of a contact hole, where no mutual diffusion takes place between the specific material concerned and the barrier metal layer. CONSTITUTION:A contact hole is filled with a silicon oxide film 7, and an AlCu wiring 8 is formed thereon. The silicon oxide film 7 is newly provided, whereby the wiring is prevented from coming into direct contact with a TiN 4 of barrier metal formed on the base of the contact hole. The silicon oxide film 7 does not react with an Si substrate 1 even if it is thermally treated as kept in contact with the substrate 1, so that alloy spikes are prevented from occurring. Therefore, even if the TiN 4 is formed thin so as to improve the density of components or to make a contact hole small, alloy spikes are prevented from occurring through the intermediary of the TiN 4 formed on the base of a contact hole.
