TOKYO–(BUSINESS WIRE)–Tanaka Holdings Co., Ltd. (Icyicaro gikuru: Chiyoda-ku, Tokyo; Umuyobozi Uhagarariye akaba n'Umuyobozi Mukuru: Akira Tanae) uyu munsi yatangaje ko Tanaka Kikinzoku Kogyo KK (Icyicaro gikuru: Chiyoda-ku, Tokyo; Umuyobozi Uhagarariye akaba n'Umuyobozi Mukuru: Akira Tanae) yubatse imiyoboro yihariye y'ibikoresho by'icyuma bya Cu byakozwe mu buryo bwa texture bya YBCO superconducting insinga (*1) kandi yashyizeho uburyo bwo gukora ibintu byinshi bukoreshwa guhera muri Mata 2015.
Mu Ukwakira 2008, Tanaka Kikinzoku Kogyo afatanyije na Chubu Electric Power na Kaminuza ya Kagoshima bafatanyije gukora substrate za mbere za Cu metal zakozwe hakoreshejwe insinga zikora cyane. Umusaruro watangiye kandi ingero zatanzwe kuva mu Ukuboza k'uwo mwaka. Iyi nsinga ikora cyane yasimbuye ikoreshwa rya Ni alloys (nickel na tungsten alloys), zahoze ari ibikoresho by'ingenzi bya substrate za textures z'ibyuma, hamwe n'umuringa uhendutse kandi uhenze (*2), bityo bigabanyiriza ikiguzi kirenga 50%. Imwe mu ntege nke za umuringa ni uko ushobora kwangirika, bishobora gutuma icyuma gito (superconducting wire cyangwa oxide buffer layer) cyakozwe kuri substrate kivangwa. Ariko, icyerekezo n'ubuso bworoshye byiyongera binyuze mu gukoresha umuti wihariye wa nickel plating urimo palladium nk'urwego rw'icyuma gikingira ogisijeni, bituma icyuma gito gikomeza guhagarara kuri substrate.
Kuva aho ingero z’ibikoresho bya Cu byashyizwe ahagaragara bwa mbere, Tanaka Kikinzoku Kogyo yakomeje gukora ubushakashatsi kugira ngo irebe ko ibintu bihamye. Gukora ibikoresho birebire byashobotse binyuze mu kunoza imiterere y’ibikoresho. Kugira ngo habeho gusubiza ibyifuzo by’imbere mu gihugu no mu mahanga ako kanya, hubatswe umurongo wihariye w’ibikorwa mu ruganda rufitwe n’ikigo muri Mata 2015. Biteganijwe ko iri koranabuhanga rizakoreshwa mu bindi bikorwa bitandukanye mu gihe kizaza birimo insinga z’amashanyarazi zikoreshwa kure kandi zifite ubushobozi bwo gutanga amashanyarazi menshi, Magnetic Resonance Imaging (MRI) na Nuclear Magnetic Resonance (NMR), zikenera imbaraga nyinshi za rukuruzi, na moteri ku bwato bunini. Tanaka Kikinzoku Kogyo igamije kugera ku giciro cya miliyari 1.2 z’amayen buri mwaka bitarenze umwaka wa 2020.
Icyitegererezo cy’iyi substrate hakoreshejwe insinga ya superconducting cyagaragajwe neza mu imurikagurisha rya kabiri rya High-function Metal Expo hagati ya tariki ya 8 Mata na 10 Mata 2015, ryabereye i Tokyo Big Sight.
*1 Insinga ya YBCO superconducting Ibikoresho bya Superconducting bitunganywa kugira ngo bikoreshwe nk'insinga idashobora kugera ku burwanyi bw'amashanyarazi. Bikozwe muri yttrium, barium, umuringa na ogisijeni.
*2 Icyerekezo Ibi bigaragaza urwego rw'icyerekezo kimwe cya kristu. Urwego runini rw'ubushobozi bwo kuyobora kristu rushobora kuboneka binyuze mu gushyira kristu mu byiciro bisanzwe.
Insinga zikora superconducting zifite umwihariko wo gukora imbaraga za rukuruzi iyo zizungurutse. Zishyirwa mu byiciro hakurikijwe ubushyuhe bw'ingenzi (ubushyuhe aho zigira superconductivity). Ubwoko bubiri ni "insinga zikora superconducting zikoresha ubushyuhe bwinshi," zigumana superconductivity kuri -196°C cyangwa munsi yayo, na "insinga zikora superconducting zikoresha ubushyuhe buke," zigumana superconductivity kuri -250°C cyangwa munsi yayo. Ugereranije n'insinga zikora superconducting zikoresha ubushyuhe buke, zisanzwe zikoreshwa kuri MRI, NMR, motorcars zigororotse n'izindi, insinga zikora superconducting zikoresha ubushyuhe bwinshi zifite ubucucike bw'amashanyarazi bwinshi (ingano y'amashanyarazi), zigabanya ikiguzi hakoreshejwe azote y'amazi mu gukonjesha, kandi zikagabanya ingaruka z'imbaraga za rukuruzi zo hanze, bityo iterambere ry'insinga zikora superconducting zikoresha ubushyuhe bwinshi ririmo gutezwa imbere muri iki gihe.
Hari insinga zikoresha bismuth (zizwi nka "bi-based" hepfo) na yttrium (zizwi nka "Y-based" hepfo) zikoresha ubushyuhe bwinshi. Bi-based zuzuzwa mu muyoboro wa feza utunganywa kugira ngo ukoreshwe nk'insinga, mu gihe Y-based zishyirwa ku gice cy'ubutaka mu buryo bwa kaseti ifite kristu zigororotse kugira ngo zikoreshwe nk'insinga. Y-based byitezwe ko izaba insinga zikoresha superconducting mu gihe gikurikiraho kuko ifite ubucucike bw'amashanyarazi bukomeye cyane, imiterere ikomeye ya rukuruzi, kandi ikiguzi cy'ibikoresho gishobora kugabanuka hagabanijwe ingano ya feza ikoreshwa.
Ibiranga insinga za superconducting zishingiye kuri Y n'iterambere rya tekiniki muri Tanaka Kikinzoku Kogyo
Ku bijyanye n'insinga zikora superconducting zishingiye kuri Y, turimo gukora ubushakashatsi n'iterambere ku "substrates za IBAD" na "substrates zifite imiterere." Imiterere y'ubushobozi bwo gutwara ibintu irushaho kwiyongera binyuze mu gushyira kristu z'icyuma mu bihe bisanzwe, bityo gutunganya icyerekezo cy'icyuma bigomba gutunganywa kuri buri cyiciro kigize kaseti. Ku substrates za IBAD, urwego rwa oxide thin film rugenzurwa mu cyerekezo runaka ku cyuma gifite imbaraga nyinshi kitagenzurwa, kandi urwego rwa superconducting rushyirwa kuri substrate hakoreshejwe laser, ikora ibikoresho bikomeye bya substrate, ariko nanone bigatera ikibazo cy'ikiguzi cy'ibikoresho n'ibikoresho. Iyi niyo mpamvu Tanaka Kikinzoku Kogyo yibanze ku substrates zifite imiterere. Ibiciro biragabanuka hakoreshejwe umuringa wo hejuru nk'ibikoresho bya substrate, ibyo kandi byongera imbaraga za mekanike iyo bihujwe n'urwego rw'ibikoresho byo kongera imbaraga hakoreshejwe ikoranabuhanga ridafite ingaruka ku cyerekezo.
Isosiyete ya Tanaka Precious Metals yashinzwe mu 1885, yubatse ibikorwa bitandukanye by’ubucuruzi byibanda ku ikoreshwa ry’amabuye y’agaciro. Ku ya 1 Mata 2010, iri tsinda ryasubiwemo hamwe na Tanaka Holdings Co., Ltd. nk’ikigo gifite imari (sosiyete nyamukuru) ya Tanaka Precious Metals. Uretse gushimangira imiyoborere myiza y’ibigo, isosiyete igamije kunoza serivisi rusange ku bakiriya binyuze mu kugenzura neza imicungire myiza no gushyira mu bikorwa ibikorwa mu buryo buhamye. Tanaka Precious Metals yiyemeje, nk’ikigo cyihariye cy’ibigo, gutanga ibicuruzwa bitandukanye binyuze mu bufatanye hagati y’ibigo by’amatsinda.
Tanaka Precious Metals iri mu cyiciro cya mbere mu Buyapani mu bijyanye n'ingano y'ibyuma by'agaciro bicukurwamo, kandi mu myaka myinshi iri tsinda ryateje imbere kandi ritanga amabuye y'agaciro mu nganda, hiyongereyeho gutanga ibikoresho n'ibikoresho byo kuzigama hakoreshejwe amabuye y'agaciro. Nk'abahanga mu by'ibyuma by'agaciro, iri tsinda rizakomeza gutanga umusanzu mu kunoza ubuzima bw'abantu mu gihe kizaza.
