     따라서, 이런한 방법에 의하면, 람다 제어는 스위치 온된다. 제어가 발생되는 지점은 분사 시간 주기의 상술한 작동에 의해 나타난다. 
     상술한 방법을 수행하기 위한 장치는 각 처리 단계를 파악하기 위한 수단을 갖는다. 
     내연 기관에 공급되는 연료량을 설정하기 위한 방법에 있어서, 부하 신호가 잘못될 때 아이들링의 경우에, 대기 부하값이 고정되고, 엔진 전류 속도가 측정되며, 이들 상술한 값에 대해 분사 시간이 특정값으로 부터 판독된다. 
     상술한 방법에 대해, 낮은 배기 가스 값은 비상 작동시에 달성된다. 또한, 촉매 컨버터는 비점화 혼합물이 드물게 설정되므로 과열로부터 보호된다.

Abstract: For laminating a web (3) with a stretched web (2), the stretching operation for the web (2) is immediately followed by feeding in the unstretched web (3) and laminating it on to a certain extent within the stretching apparatus (4) by utilising the stretching heat - preferably after independent preheating - so that a heat-laminated multilayered web (13) is formed, in which both webs (2 and 3) may consist of the same or the same type of material, which is particularly favourable for reprocessing. The advantages of such a composite web comprising a stretched web and an unstretched web are thus achieved without adhesive being required for forming the bond.

Patent KR-0177176-B1 (KR)
Title: Process for the production of beta lactames
Inventor: JOSE DIAGO
IPC: C07D499/68
Filed: 1991-01-21
Granted: 1999-03-20
Abstract: A process for the production of an 6-alpha-aminoacyl-penicillin or 7-alpha-aminoacyl-desacetoxy-cephalosporin comprising the steps   (i) producing a mixed carboxylic acid anhydride by reaction of an N-substituted vinyl alpha-amino acid with an appropriate acylating agent in a methyl-(C2-4)alkyl ketone, di-(C2-4)alkyl ketone, (C1-3) alkanoic acid butyl ester or an aromatic hydrocarbon as a solvent, (ii) reacting the mixed carboxylic acid anhydride obtained in step (i) with a solution or a suspension of 6-APA or derivative thereof in non-halogenated solvent, and (iii) isolating a 6-alpha-aminoacyl-penicillin or a 7-alpha-aminoacyl-desacetoxycephalosporin obtained by adding water to the reaction mixture obtained in step (ii) to form a two-phase system and isolating a 6-alpha-aminacyl penicillin or 7-alpha-aminoacyl-desacetoxy-cephalosporin obtained by separating the aqueous phase from the organic phase.

Title: Time delay comparision noise detecting circuit
Inventor: PARK SANG-YUN
IPC: H03K5/22
Filed: 1991-05-28
Granted: 1993-09-11
Abstract: The  noise  detecting  circuit  by  time  delay  comparision includes a time delay unit for controlling  a  delay  time  of  an input signal in a delay time controlling  section  and  delay  the input signal as much as the  controlled  delay  time  in  a  delay section, a noise recognizing level adjusting section for adjusting a level recognized as a noise when the delay  signal  is  compared with an original signal of the delay section, a comparing  section for comparing the original signal of which level  is  adjusted  in the noise recognition  level  adjusting  section  with  the  delay signal to detect noise,  a  switching  section  switching  by  the output from the comparing section for eliminating the noise of the output signal, and a signal restoring section  for  restoring  the original signal  eliminated  together  with  the  noise  by   the switching section to the level  before  the  elimination,  thereby eliminating the noise component only and further a pulse noise  by adjusting the delay time. Also, the error from the original signal is maximally reduced even after eliminating the noise by restoring the eliminated portion.

Title: Carrier stock with tear-open tabs
Inventor: MARCO LESLIE S
IPC: B65B11/00
Filed: 1991-06-10
Granted: 1995-01-26
Abstract: Carrier stock (10) is formed from a single sheet of resilient polymeric material, such as low density polyethylene, for machine application to substantially identical containers (12). The stock (10) is severable to form individual carriers (20) with container-receiving apertures (14), as defined by band segments, which include outer segments (22) formed with tear-open tabs (30). Each tab (30) and preferably the outer segment (22) have multiple slits (32,40,50,52), which are arranged to define tearable bridges (42,54,56,58) that can be easily torn by a user pulling on such tab (30), whereby the outer segment formed with such a tab (30) can be easily severed to release a container from the aperture (14) bounded partly by such a segment (22). <IMAGE>
