Granted: 1997-01-21
Abstract: Sheet material 4 is stretched transversely into longitudinally extending pleats by passage between intermeshing grooved rollers A and B having circularly or helically extending grooves in their surfaces. Each groove is formed of a base 6a, 6b and side walls 5a, 5b inclined outwardly to a peak 7a, 7b. Portions of adjacent side walls 5a and 5b are parallel to one another.

Title: Acknowledge back pager with apparatus for controlling transmit frequency
Inventor: KAZIMIERZ SIWIAK
IPC: B63B21/48
Filed: 1988-12-12
Granted: 1998-10-01
Abstract: An acknowledge back (ack-back) pager is provided for use in a paging system including a central station which transmits a group of message signals to a group of ack-back pagers which are addressed as a group. The users of the group of addressed ack-back pagers indicate a response to their respective pagers thus providing ack-back data. The pagers in the group of addressed ack-back pagers then simultaneously transmit back to the central station their ack-back data on different frequency sub-bands, a different frequency sub-band being allocated to each of the pagers in the group. To accurately control the ack-back transmit frequency, the pager receives and down-converts the FRX signal thus producing a down-converted FC signal, the frequency of which is measured and stored. The pager selects which sub-band of a plurality of frequency sub-bands within a predetermined range of frequencies is to be used for transmission of the ack-back signal. The pager determines a frequency offset FD corresponding to the selected sub-band, such offset being with respect to a predetermined frequency within such range of frequencies. The pager generates an acknowledge back signal at a frequency (FC+FD)-FCTX and up-converts such signal to a transmit frequency FTX corresponding to said selected sub-band, FCTX being the frequency of a down-converted sample of the FTX signal.

     또, 장착체가 축받이체에, 장착체의 탄성변형을 통하여 때고 붙임이 자류롭게 걸어맞춤되어 있기 때문에, 장착체의 축받이체로의 떼고 붙임을 용이하게 행함과 동시에, 장착체를 축받이체에서 떼내면, 공급관을 개재하지 않고, 직접, 손수 저류 요홈부내에 윤활제를 공급 할수도 있다. 
     즉, 축받이체로의 장착체의 착탈에 의해, 저류 요홈부내로의 윤활제의 공급을, 공급관을 통하여 행하거나, 직접, 손수 행하거나를 용이하게 선택 할수 있음과 동시에, 축받이체 자체에, 공급관을 붙임고정 하기위한 구조를 부가함으로 축받이체 자체의 구조를 간소화 할수 있다.

Title: Manufacturing method of bipolar transistor
Inventor: KIM MUN-HO
IPC: H01L29/73
Filed: 1991-03-25
Granted: 1994-06-18
Abstract: The method of fabricating bipolar transistor comprises the steps of forming an N-type polysilicon and nitride pattern on an active region, forming a sidewall on the sides of the pattern, selectively growing epitaxial layer between the sidewall and the field oxide, highly doping the epitaxial layer with P-type, performing heat treatment to the polysilicon layer and highly doped epitaxial layer to form emitter and base region, depositing a metal and then heat treating it to form salicide layer, and selectively removing the salicide layer. The method simplifies formation of electrode and improves the transistor performance.
