Impompo yeTurbomolecular kwii-Crystal oscillators

I-Crystal oscillator ixhaphake kwizinto zeewotshi kwiisekethe, eyona ndima yayo iphambili kukubonelela ngokuhamba rhoqo kumakhadi emizobo, kumakhadi enethiwekhi, kwibhodi yomama nakwezinye iindawo, ezisetyenziswa ngokubanzi kwizixhobo zolwazi, kwiitheminali eziphathwayo, kwizinxibo ezifanelekileyo, kwi-Intanethi yezinto kunye amanye amacandelo. Ukusebenza okuqhelekileyo kweesekethe ze-elektroniki kuxhomekeke kwisigxina, esizinzileyo "isiginali yewotshi", phantsi kweemeko zokusebenza eziqhelekileyo, ukuchaneka ngokupheleleyo kweekristale eziqhelekileyo kunokufikelela kuma-50 kwisigidi.

Eyona nto iphambili ekusebenzeni kwe-quartz yikristale, ikristale etsobhileyo enamacala amathandathu enekhemikhali yokwenziwa kwesilicon dioxide (SiO2).
I-Quartz yinto ekrwada yabavelisi ngenxa yeempembelelo zayo ze-piezoelectric ye-positive (amandla oomatshini → umbane), inverse (umbane → amandla oomatshini). Ukuba uxinzelelo lusetyenziswa ecaleni kweeshafti okanye koomatshini bokufakwa kwizikhonkwane ze-quartz ukukhubaza iifers, ezi ndawo zimbini zijolise ngqo kula mazembe zivelisa ukuhlawulwa kombane, into eyaziwa njengempembelelo yeepezoelectric. Ukuba umhlaba wombane ufakwa kuwo omabini amacwecwe e-quartz crystal, isiciko sokwandisa okanye sokucinezela kwicala leshafti kunye ne-axis yomatshini, into eyaziwa njengempembelelo yoxinzelelo. Ngokusekwe kolu phawu, xa i-quartz crystal ibekwe kwindawo ethembekileyo yombane, ivolumu yekristale icinezelwa okanye yolulwa ngamaxesha athile, yenza ukungcangcazela komatshini yikristale. Xa ubude bentsimi yotshintshwano bulingana nobuninzi bemeko yesandi esingqiniweyo, isandi sokungcangcazela koomatshini sisesona sikhulu, sikhokelela kwisandi.

Kwimveliso, iinkqubo ezine zesilivere, ukuLungisa, ukudibanisa kunye nokuvavanywa kuya kuncedwa kwimeko yokucoca apha ngezantsi.
Umatshini wesilivere
Kwinkqubo yokuvelisa izinto zekristale ze-quartz, ukucwangciswa kwesilivere enamacala amabini kuyafuneka kumhlaba osezantsi osikiweyo ukwenza i-electrode esecaleni. Kule minyaka imbalwa idlulileyo, indawo ephezulu eyenziwe ngoomatshini besilivere eyenziwe ziimpompo zokusasaza. Ngenxa yeemfuno zomgangatho kunye nokusebenza kwamandla, impompo ye-turbomolecular isetyenziswa ngokuthe ngcembe ukubuyisela iimpompo zokusasazeka kolu shishino.
Ukucoca umatshini
Indlela ye-Ion etching iyamkelwa ukuze ihlengahlengise ubukhulu be-elektrode yomphezulu womhlaba, ukuze i-crystal resonator frequency ifikelele kwithagethi ye-oscillation frequency. Izixhobo ezixhotyiswe ngephenyane lokuhambisa kabini liyafumaneka nge-1280 yeekristale oscillation, zomsebenzi wexesha lokwenyani lokujonga ikristal oscillation frequency, inokubamba izinto zentsimbi ezingama-64 ngaxeshanye. Igumbi lokucoca umatshini wokucoca-hlula lihlukaniswe kwigumbi lokulungiselela kunye negumbi lokucoca kakuhle. Xa izixhobo zivuliwe, isidanga segumbi lokulungiselela liya kuncitshiswa ukusuka koxinzelelo lwomoya ukuya kuthi ga kwiPa, isidanga segumbi lokucoca kakuhle liya kuthi ekugqibeleni licuthwe liye kwi-10-3 ukuya kwi-10-4 Pa. Iimpompo zemolekyuli zisetyenziselwa ukuvelisa inkunkuma ephezulu kwigumbi lokucoca kakuhle.
Umatshini Welding
Inkqubo yokuwelda kukutywina isiciko esingaphezulu kunye nesiseko ukuqinisekisa ukuba inqanaba lokuguga kwemveliso liyahlangabezana neemfuno. Apho ikristale engacacanga inokugcwaliswa ngokuthe ngqo ngegesi ye-nitrogen ukutywina, ngelixa ikristale esebenzayo kufuneka yongezwe ukungcangcazela ngaphambi kokutywina. Kwinkqubo yokubamba inkunkuma yenxalenye yomatshini wokutywina, inkunkuma ephezulu ifunyanwa ngokusebenzisa impompo yemolekyuli.
Kule minyaka idlulileyo, ngokukhula ngokukhawuleza kwezicelo ezisezantsi ezinje nge5G, izixhobo zombane zeemoto kunye neetheminali ezihambayo, umzi mveliso wekristale ungenise amathuba amatsha. Njengeengcali zeshishini lesisombululo, i-KYKY inobutyebi bamava kwicandelo le-crystal oscillator, ibonelele ngoluhlu olupheleleyo lweemveliso zokucoca kunye nezisombululo ezenziwe ngokwezifiso. Kwixesha elizayo, i-KYKY iya kuqhubeka nokumba nzulu kumacandelo oshishino, ukubambelela ukubonelela abathengi ngeemveliso ezisemgangathweni kunye neenkonzo.
