Granted: 1995-10-09
Abstract: The method for manufacturing a biodegradable plastic foam is characterized by reacting a polyol component with a polyisocyanate component in the presence of the activated plant (i.e. coffee bean) remainders by the UV irradiation, electron beam irradiation or plasma treatment. The polyol component is pref. ethylene glycol, polypropylene glycol, pentaerythritol, polyester polyol or 1, 4-butanediol, and the polyisocyanate component is pref. diphenylmethane diisocyanate, naphthalene diisocyanate, phenylene diisocyanate or triphenylmethane triisocyanate.

Title: Disc play having double speed function

IPC: G11B19/20

Abstract: PURPOSE: A disk player having a double speed function is provided to allow a spindle motor servo circuit, related to the generation of signals controlling a spindle motor, and a phase control circuit to selectively control signals correspondingly to designated disk driving speeds, so that a single speed or a double speed can be enabled. CONSTITUTION: In a spindle motor servo circuit, the first phase comparison unit(31) compares the phases between a reference signal and an input signal when a disk player is operated in a single speed, and outputs the compared result as a pulse width modulation signal. A driving voltage generation unit(32) low-filters the pulse width modulation signal to a gain corresponding to the speed of the disk player, and generates the filtered result as a driving voltage. A disk driving unit(33) drives the disk player in a speed corresponding to the driving voltage. A synchronizing signal division unit(34) divides a synchronizing signal read from the disk at a division rate corresponding to the speed, and outputs the divided result as the input signal. In a phase control circuit, an EFM(Eight to Fourteen Modulation) signal control unit divides an EFM signal read from the disk at a division rate corresponding to the speed, for outputting. The second phase comparison unit compares the phase of a signal outputted from the EFM signal control unit and an oscillating signal. The second low filter low-filters a signal outputted from the second phase comparison unit. A gain control unit controls the low-filtered signal to a gain corresponding to the speed. A voltage control oscillator generates a signal having a frequency corresponding to the voltage supplied from the gain control unit. And a frequency conversion unit divides a signal outputted from the voltage control oscillator at a division rate corresponding to the speed, for outputting.

Abstract: 유리판 벤딩방법에 있어서, 유리판은 연속로(1)내의 수평위치에서 벤딩온도로 가열되고 그 다음 벤딩 챔버가 컨베링 평면위로 위치 설정된 블록 벤딩 몰드(7)에 대향해 상향으로 유동하는 고온 가스흐름에 의해 프레스된다. 벤딩 유리판(3′)은 이동가능한 형상 설정링(13) 위에 올려지고 이것에 의해 다음의 냉각 스테이션(16)으로 이송된다. 유리판(3)은 흡입판(23)에 의해 연속로(1)의 컨베링 롤러 트레인(2)에서 상승되어 가동 이송링(28) 위에 올려진다. 유리판(3)은 이송링(28)에 대해 위치 설정된다. 이송링(28)의 도움으로 유리판(3)은 벤딩 챔버로 이송되며, 이송링(28)의 단부위치에서는 유리판(3)이 벤딩 몰드(7)에 대해 소정의 단부위치를 차지한다.
