Title: Production of magnetic head
Inventor: OGAWA TAKAHIRO
IPC: G11B5/133
Filed: 1986-02-19
Abstract: PURPOSE:To considerably decrease defective working and to improve yield by preliminarily depositing a glass film having the softening point substantially lower than the softening point of a glass rod for welding on the slope of a winding groove of the 1st ferrite wafer and the contact surface of the 2nd ferrite wafer to be joined to the 1st ferrite wafer and welding the glass thereby joining the wafers. CONSTITUTION:The glass rod 3' for welding is inserted and disposed into an insertion groove 7 and in succession, the wafer is disposed in a heating furnace where the entire part is heated to the temp. above the softening point of the glass rod 3'. The glass film 13 melts as well in this stage and the 1st and 2nd ferrite wafers 2'', 2' are joined in other parts as well except in the groove 6, 7, 8. The glass film 13 part in opposite contact with the winding groove 6 and the glass film 13 on the slope 14 of the winding groove of the 1st ferrite wafer 2'' exhibit the effect of adequately guiding the glass 3 consisting of the softened glass rod into the winding groove 6. The generation of clogging by the excessive intrusion of the glass 3 into the winding groove 6 and the drop-out of the glass occurring in the failure of the glass intrusion are consequently obviated.

Abstract: PURPOSE:To make a signal processing circuit small in size and simple and to reduce the consumption of electric power while maintaining high accuracy by providing the signal processing circuit only to one output of the respective two outputs from one or two sets of photosemiconductor postion detecting elements (PSD). CONSTITUTION:When the output from a control circuit 18 is at an H level, a switching transistor 16 turns on, and a switching transistor 14 turns off. Then the terminal B of PSD2 is opened, and signal currents IA and IB are superposedly outputted from a terminal A. When the output from the circuit 18 goes to an L level, the TR16 turns off and the TR14 is turned on by the output from a constant current circuit 15. Then only the signal current IA is outputted from the terminal A of the PSD2 and the current IS from the trerminal B flows through the TR14 to a reference power source KVC. The current IA is subjected to a current-voltage conversion by an operational amplifier 11 and a load circuit 12 and after the current is amplified, the current is fed to a signal processing circuit 13 in the succeeding stage, where the current is calculated with the sum signal (VA+VB) latched at the H level and the signal corresponding to the incident position of the PSD which is normalized in VA/(VA+VB) is outputted.
