Title: Resillient upholstery pad
Inventor: JONG MIN-U
IPC: B68G7/06
Filed: 1992-05-08
Granted: 1995-06-26
Abstract: A method of forming a curved figure in an air cushion pad article such as a shoulder piece is realized in heat-fusing the double layered plastics resin film (3, 4) along the brim with a suitable shape so as to form a pad seat (5) having a semi-circular arc shape (2). The both ends of the semi-circular arc shape are creased by the heat-fusing process so as to form several semi-oval shapes (6). A lot of heat-fusing spots (7) are processed in the inner prortion near the center line (1) of the seat. The size of the heat-fusing spots near the center circle of the arc-shaped seat is larger than that of the spots near the center point (1) and the semi-oval shapes. The portion near the center circle, where the distance between adjacent spots is relatively shorter, may be shrinked less than the portions of the remainder.

Abstract: 본 발명은 엘리베이터의 통신선로 제어장치에 관한 것으로, 일반적인 엘리베이터는 통신라인이 하나밖에 없고 또한 통신선로에 각 노드의 통신포트가 1:1로 접속되어 있으므로 통신라인 하나에 의존도가 너무 높다. 따라서 상기 통신선로 하나에 이상이 생기면 전체 시스템은 운행이 불가능하게 될 수 밖에 없는 문제점이 있었다. 
     이와 같은 종래의 문제점을 감안하여, 본 발명은 예비 통신선로를 마련하여 놓고 각 노드에는 통신선로를 교체할 수 있는 릴레이를 삽입시켜 놓은 후 전체 노드의 동기를 맞춰놓고, 각 노드에서는 각자 자기 노드의 통신상태를 점검하여 이상이 발생하면 스스로 릴레이 접점을 절환하여 통신선로를 교체할 수 있도록 하며, 이상이 없는 노드들은 메인노드의 지령에 따라 릴레이를 구동하여 전체모드가 통신선로를 바꾸도록 함으로써 사용중이던 통신선로에 장애가 생겨도 전체 시스템에는 아무런 영향을 주지 않는 신뢰성 높은 시스템을 구현할 수 있게 되는 효과가 있다.

Title: Clutch mode control method
Inventor: SLICKER JAMES MELVIN
IPC: B60W30/18
Filed: 1993-12-07
Granted: 2000-04-01
Abstract: A friction clutch (20) coupling an engine (10) and a gear transmission (30) of a vehicle is controlled by a microprocessor based circuit using logic which defines operating modes according to engine (10) and clutch (20) conditions. During the time of clutch closure, when the vehicle is starting from rest in a startup or launch mode, the throttle or other engine control signal is restrained from quickly responding to the accelerator pedal (11). This avoids engine overspeeding which results from generating high torque before sufficient clutch capacity has been achieved. The control signal is developed as a function of the pedal position under control of throttle logic which, in turn, is dependent on clutch operating modes defined by the clutch logic. The clutch operating modes are four modes for automatic clutch operation comprising touch point approach mode which prohibits a throttle signal during initial clutch movement, creep mode or startup mode after touch point (81) occurs, and lockup mode for completing clutch closing when low clutch slip is attained. A non-automatic mode is entered before the accelerator pedal (11) is depressed or when engine (10) stall conditions are detected. <IMAGE>   <IMAGE>
