Mazuva ano, anenge munhu wese ane smart phone. Uye imwe neimwe smart phone inofanira kuuya neSIM card. Saka chii chinonzi SIM card? SIM kadhi inozivikanwa semunyoreri kuziva module. Inoita basa rakakosha muGSM dhijitari nharembozha system. Icho chikamu chakakosha chenharembozha uye kadhi rekuzivikanwa kune yega yega GSM nharembozha mushandisi.
Sezvo foni yakangwara ichiwedzera kufarirwa, musika weSIM kadhi unowedzera kukurumidza kukurumidza. SIM card ichip card ine microprocessor mukati. Iyo ine ma module mashanu: CPU, RAM, ROM, EPROM kana EEPROM uye serial yekutaurirana unit. Imwe neimwe module ine basa rayo rega.
Mune diki SIM kadhi, iwe unozoona kune mamwe mabarcode uye serial nhamba yechip. Nzira yechinyakare yekuadhinda paSIM kadhi iri kushandisa inkjet kudhinda. Asi zviratidzo zvakadhindwa ne inkjet kudhinda zviri nyore kudzimwa. Kana mabhakodhi uye serial nhamba dzadzimwa, manejimendi uye kuteedzera kweSIM makadhi kunozonetsa. Kunze kwezvo, SIM makadhi ane inkjet akadhindwa mabhakodhi uye serial nhamba zviri nyore kukopwa nevamwe vagadziri. Naizvozvo, inkjet kudhinda kunosiyiwa zvishoma nezvishoma nevagadziri veSIM makadhi.
Asi ikozvino, nemuchina wekumaka laser, dambudziko re "nyore kudzimwa" rinogona kugadziriswa zvakakwana. Iyo barcode uye serial nhamba yakadhindwa nelaser yekumaka muchina ndeyekusingaperi uye haigone kuchinjwa. Izvi zvinoita kuti ruzivo urwu ruve rwakasiyana uye harugone kudzokororwa. Kunze kwezvo, laser yekumaka muchina inogona zvakare kushandiswa mune zvemagetsi zvikamu, PCB, zviridzwa, nharembozha kutaurirana, chaiyo yekuwedzera, nezvimwe.
Izvo zvataurwa pamusoro apa mashandisirwo e laser yekumaka muchina ane chinhu chimwe chakafanana - nzvimbo yekushanda idiki. Izvi zvinoreva kuti maitiro ekumaka anofanira kunyatsojeka. Uye izvi zvinoita kuti UV laser ive yakanyanya kunaka, yeUV laser inozivikanwa nekunyanya kurongeka uye "kutonhora kugadzirisa". UV laser haizobatanidze zvinhu panguva yekushanda uye iyo inopisa inobata nzvimbo idiki, saka inenge isina kupisa inobata pane izvo zvinhu. Nokudaro, hapana kukuvara kana deformation ichakonzerwa. Kuti uchengetedze chokwadi, UV laser inowanzouya neyakavimbika
mvura chiller unit.
S&A Teyu CWUL yakatevedzana mvura chiller unit ndiyo yakanakira sarudzo yekutonhodza UV laser yekumaka muchina. Iyo inoratidzira yakakwira dhigirii yekurongeka kwe ± 0.2 ℃ uye mabatiro akabatanidzwa anobvumira kufamba kuri nyore. Refrigerant ndeye R-134a inoshamwaridzana nemamiriro ekunze uye inogona kudzikisa kukanganisa kunharaunda. Tsvaga rumwe ruzivo nezve CWUL yakatevedzana mvura chiller unit pa
