Title: Color liquid-crystal display device
Inventor: NAKAMURA TAKU
IPC: G02F1/1335
Filed: 1999-10-14
Granted: 2004-11-21
Abstract: A phase difference plate for delaying the phase of incident light for lambda/4 and a liquid-crystal layer for shifting the incident light by lambda/4 according to the applied voltage are provided between a polarizing plate and a selective reflection layer formed of cholesteric liquid crystal. A first color filter layer is provided on the polarizing plate side of the selective reflection layer. On the back side of the selective reflection layer, a second color filter layer constituting a band-pass filter is arranged. On the back side of the second color filter layer, a backlight is provided. When a liquid-crystal display device functions as a reflective liquid-crystal display device, light entering through the polarizing plate is reflected totally by the selective reflection layer and passes through the first color filter layer twice. When the liquid-crystal display device functions as a transmission liquid-crystal display device, light from the backlight passes through the selective reflection layer. Then, the light passes through the second and first color filter layers once and is outputted.

Title: Wireless communication system equipped with a mechanism for restoring conversation and its processing method
Inventor: SU SHU-CHIN
IPC: H04B7/26
Filed: 2000-02-23
Granted: 2001-12-21
Abstract: This invention introduces a wireless communication system equipped with a mechanism for restoring conversation and its processing method. It provides a service to restore conservation after the handset is interrupted. In this system, the first base station provides wireless resources to the handset before it is interrupted. During the interruption, the first base station activates a timing device and reserves the wireless resources assigned to the handset. If the handset sends out a request for restoration service during the period defined by the timing device and the first base station receives the request, the original wireless resources can be restored immediately to complete the service for conversation recovery. If the handset does not send out a request for restoration service during the period, the mobile switching center can retrieve the wireless resources through the first base station. If the handset moves from the first base station to the second station during the interruption and the second base station receives the request for restoration service in the same period, the mobile switching center can restore the communication services for mobile units through the second base station.

Title: A servo format for hard disks, preferably hard disks
Inventor: BERGMANS JOHANNES W M
IPC: G11B20/14
Filed: 2000-05-08
Granted: 2002-02-21
Abstract: A new embedded-servo format is proposed for use in disk drives, preferably hard disk drives. It is based on biphase modulation (more generally, p-phase modulation, where p > 1) and offers significant advantages, in terms of SNR and timing content, over existing formats. It is shown that for biphase, at the low linear densities typically employed for servo information, near maximum-likelihood performance may be attained by a simple bit- detector consisting of a full-response linear equalizer and a binary slicer. When compared with an optimal detector for the commonly used technique of dibit signalling, a SNR gain of some 4 dB is achieved. The same equalizer may be used as the basis for near-maximum-likelihood position error signal (PES) amplitude estimation and timing recovery. Investigations carried out on a practical servo demodulator based on a 5th order analog filter show that, at typical linear densities, this ideal performance is closely approached. The equalizer has a band-pass character and yields excellent suppression of the effects of thermal asperities and magneto resistive (MR) head asymmetry.
