Pierwszenstwo: Zgloszenie ogloszono: 31.05.1973 Opis patentowy opublikowano: 10.06.1974 70128 D.42t\ 5/14 MKPdlb 5/14 CZYTELNIA Urzedu Pa^l«^Pn Twórcywynalazku: Pawel Beno, Andrzej Szyller, Zdzislaw Malinowski Uprawniony z patentu tymczasowego: Warszawskie Zaklady Urzadzen Informatyki „MERAMAT", Warszawa (Polska) Wielosladowa, ferrytowa glowica magnetyczna, Przedmiotem wynalazku jest wielosladowa, ferrytowa glowica magnetyczna ze szczelinami wypelnianymi lutowiem szklanym, wykluczajaca powstawanie pecherzy.Znane rozwiazania sposobu wypelniania szczelin roboczych, szczególnie glowic ferrytowych pracujacych w bezposrednim kontakcie z nosnikiem magnetycznym przesuwanym po czole glowicy badz tez glowicy magne¬ tycznej przesuwajacej sie w stosunku do stojacej tasmy, jak równiez jednoczesnego wzajemnego przesuwania sie tych elementów, nie pozwalaja na uzyskiwanie wypelnienia lutowiem bez powstawania pecherzyków powietrz¬ nych.Stosowany proces technologiczny wypelniania szczelin glowic ferrytowych lutowiem szklanym wedlug polskiego patentu nr 58 892 oraz innych patentów polskich czesciowo traktujacych sposób wypelniania szczelin, a mianowicie nr nr 55 826 i 54 159, nie pozwala uzyskac bezpecherzowego wypelniania szczeliny z uwagi na duze powierzchnie konieczne przy stosowaniu naddatków technologicznych dla obróbki czola.Celem wynalazku jest usuniecie wyze; wspomnianych niedogodnosci. Cel ten osiagnieto przez odpowiednie konstruowanie obwodu magnetycznego polegajace na tym, ze zawiera wglebienie o dowolnym profilu wjednej lub wiecej laczonych czesciach obwodu magnetycznego w szczelinie roboczej lub pomocniczej, sluzace do swobodnego ujscia powstajacych pecherzy w wypelniejacym te szczeliny lutowiu szklanym szczególnie na glebo¬ kosci stanowiacej czesc uzyteczna glowicy z wyprofilowanym czolem o dowolnym zarysie.Zastosowanie wglebienia w szczelinie glowicy magnetycznej wypelnionej lutowiem szklanym wedlug wynalazku odznacza sie zmniejszeniem przestrzeni jaka wypelnia lutowie w stosunku do czesci uzytecznej szczeliny.Wielosladowa, ferrytowa glowica magnetyczna wedlug wynalazku zostala przedstawiona na rysunkach, na których fig. 1 przedstawia obwód magnetyczny w widoku a fig. 2 szczegól A tego obwodu.Jak przedstawiono na zalaczonych rysunkach glowica magnetyczna wedlug wynalazku sklada sie z dwóch czesci 1 i 2 stykajacych sie ze soba tworzac szczeliny 3 i 4, z których jedna posiada wglebienie 5. Szczeline ta wypelnia sie roztopionym lutowiem szklanym 6.Podczas wypelniania szczeliny roboczej 4 lutowiem szklanym 6, lutowie to wypelnia ja co najmniej na glebokosci a3. Nastepnie zaczyna sie proces wypelniania wglebienia 5 posiadajacego glebokosc b2 wieksza od2 70 728 szerokosci szczeliny b^ Przez zastosowanie wglebienia 5 zmniejszono opór stawiany lutowiu 6, które obecnie szybciej zapelnia szczeline eliminujac powstawanie pecherzy.

PL PLPriority: Application announced: May 31, 1973 Patent description was published: June 10, 1974 70128 D.42t \ 5/14 MKPdlb 5/14 READING ROOM of the Office Pa ^ l «^ Pn Inventors: Pawel Beno, Andrzej Szyller, Zdzislaw Malinowski Authorized by a provisional patent: Warszawskie Zaklady Urzadzen Informatyki "MERAMAT", Warsaw (Poland) A multi-track, ferrite magnetic head. The subject of the invention is a multi-track, ferrite magnetic head with gaps filled with glass solder, preventing the formation of bubbles. Known solutions for filling working gaps, especially ferrite heads working in direct contact with a magnetic carrier moving along the head of the head or the magnetic head moving in relation to the standing tape, as well as the simultaneous movement of these elements, do not allow for solder filling without the formation of air bubbles. The technological process of filling the gaps of ferrite heads with glass solder according to Polish patent No. 58 892 and other Polish patents partially dealing with the method of gap filling, namely No. 55 826 and 54 159, does not allow to obtain a bubble-free gap filling due to the large surfaces necessary for the application of technological allowances for the processing of the forehead. the invention is to remove the above; these inconveniences. This goal was achieved by the appropriate construction of the magnetic circuit, consisting in the fact that it contains a cavity of any profile in one or more connected parts of the magnetic circuit in the working or auxiliary gap, used to freely release the bubbles formed in the glass solder filling these gaps, especially on the bone soil forming part of the Useful head with a contoured face of any contour. The use of the indentation in the slot of the magnetic head filled with glass solder, according to the invention, is characterized by a reduction in the space that the solder fills in relation to the part of the useful slot. The multi-track, ferrite magnetic head according to the invention is shown in the figures, in which Fig. 1 shows the magnetic circuit in a view and Fig. 2 of the details A of this circuit. As shown in the attached drawings, the magnetic head according to the invention consists of two parts 1 and 2 touching each other to form gaps 3 and 4, of which one has a cavity 5. This gap is filled with molten glass solder. 6. When filling the working gap 4 with glass solder 6, the solder fills it at least to a depth of a3. The process of filling the cavity 5 having a depth b2 greater than 2 70 728 of the slot width b is then started. By using the cavity 5, the resistance to the solder 6 is reduced, which now fills the slot faster, eliminating the formation of bubbles. The recess 5 in the production process is removed as it is in the part of the processing allowance removed along the curve 7 with the a2 dimension being maintained. PL PL
