Title: System for transferring information using an information carrier
Inventor: BLUETHGEN BJOERN
IPC: G09B5/06
Filed: 1989-01-19
Granted: 1998-05-15
Abstract: The application refers to is a system for transferring audio and/or video information via an information carrier e.g. DAT, CD or CDV. In the R-W subcode channel of the CD-signal textual information about the audio and/or video signal has been recorded. This information is divided in packets. Packets containing information of different categories are interleaved. After reading the information from disc the packets of a selected category are separated from information read. This system of transferring additional information allows the use of an own packet category for each of a number of different languages, so that a user can select language with which he is familiar at most. Further, menu information, comprising coded menu text lines and commande codes, are recorded in the R-W subcode channel for interactive control of the read-out of the audio and/or video information or the control of other connected devices.

Abstract: 오디오 신호를 고품질로 코딩하기 위한 하이브리드 코딩 기술은 다수의 보조 대역을 얻기 위해 정제된 보조 대역 필터링 기술을 사용한다. 보조 대역에 대한 잡음 마스킹 임계치는 각각의 주파수 대역 또는 단일 주파수에 적용될 수 있는 새로운 음조 측정법을 사용하여 정해진다. 정해진 임계치에 따라, 입력 신호는 코드화되어 감소된 비트 발생율에서 양호한 품질을 얻을 수 있다.

Title: Fly-wheel system
Inventor: CHO YOUNG-JE
IPC: H02K7/00
Filed: 1991-08-14
Granted: 1996-06-12
Abstract: The fly-wheel system consists of a starting fly-wheel driven by a motor(10), an additional weight to the starting fly-wheel in order for increasing inertia wholly, and a controller. When the motor(10) is started, the additional weight is added gradually to the starting fly-wheel(100), and when the motor is stopped, the additional weight is released from the starting fly-wheel(100). The additional weight composed of sand, metal slag or grit contained in a weight tank(200).

Title: Semiconductor device isolation method
Inventor: LEE HYONG-SOP
IPC: H01L21/48
Filed: 1991-08-24
Granted: 1994-07-06
Abstract: The isolation method includes the steps of sequentially forming a first oxide layer 2, a buffer layer 3, a nitride layer 4 and a second oxide layer 5 on a silicon substrate 1, selectively etching second oxide layer 5, nitride layer 4, buffer layer 3 and first oxide layer 2 to form an isolation pattern, forming a spacer 21 on the inner side of the pattern, ion-implanting into the exposed portion of silicon substrate, selectively depositing a polysilicon on the exposed portion of the substrate 1 and selectively oxidizing the polysilicon to form a polysilicon oxide layer 8, etching back the polysilicon oxide to the nitride layer 4, and sequentially removing the nitride layer 4, buffer layer 3 and first oxide layer 2 to form an isolation oxide 10, thereby improving the isolation characteristics.
