Abstract: A difference is detected between a first partial speed pattern presently serving as the final speed pattern and a second partial speed pattern to be next transferred from the first one to serve as the final speed pattern after a transition period from the first partial speed pattern toward the second one. A transition signal is output when the detected difference reaches a predetermined value corresponding to a speed difference caused by a whole amount of variation of the acceleration or deceleration over the transition period. From the output transition signal, a speed variation at a certain point in time is calculated derived from a variation of the acceleration or deceleration during the remaining duration of the transition period from the certain point time.

Title: Modem speed changing method for fax
Inventor: IM NAM-SOP
IPC: H04N1/00
Filed: 1991-07-25
Granted: 1993-10-14
Abstract: This method is about the Modem Speed change in  FAX  systems, especially  in  domestic  and  international   communication   and provides a means to switch to and from domestic and  international modes. The method checks transmissions, checks if transmission  is domestic or international, sets the receiving speed to maximum  if call is domestic, sets modem speed and line condition if  call  is international, sends documents after checking the  area  of  call, thus controlling the modem speed according  to  the  dialed  phone number.

Title: Recording or/and play-back device of optical tape
Inventor: HWANG WON-JAE
IPC: G11B7/00
Filed: 1991-10-21
Granted: 1993-12-24
Abstract: The system has a playback head with a laser  diode  providing an output to a collimator lens, followed by an aperture  and  beam splitter with a quarter wavelength plate. The latter  charges  the linear polarised light into circular polarised light and  this  is focussed onto the tape. The reflected signal is reconverted and is directed by the beam splitter to a focussing lens in-front of  the photodiode detector. More information can be stored than  that  of optical disc. The  system  has  simple  construction  and  reduces mechanical noise.
