Title: Current addition type digital/analog local conversion circuit by load resistance circuit
Inventor: KAMEMOTO KAZUHIRO
IPC: H03M1/80
Filed: 1982-10-28
Abstract: PURPOSE:To select an analog output voltage at a wide range by connecting a switching means to one end of a load resistor and a current mirror circuit to the other end and connecting an analog output voltage outputting resistor to the output side of the current mirror circuit. CONSTITUTION:An additional current flowing into the common terminal of load resistors R1-Rn becomes the input current of the current mirror circuit 13. If the additional current value flowing from the connection point between the base B and collector C of a transistor (TR) Q11 into the common terminal side of the load resistors R1-Rn is I, the base current of the TR Q11 is IB, the emitter current is IE1, the collector current, base current and emitter current of a TR Q12 are I2, IB2 and IE2 respectively, IE1=I1-IB2, IE2=I2+IB2 are formed. If the drop voltage VBE between the base and emitter of the TR Q11 is equal to that of the TR Q12, IE1=IE2 is formed, so that I1=I2+2IB2 is also formed. If the current amplification factor of the TR Q12 is sufficiently high, IB2 can be neglected, so that I1=I2 is formed. Therefore, the I2 can be taken out from an output resistor R0 as the output current of the current mirror output circuit 13.

Title: Production of floating type magnetic head
Inventor: YABE YASUHIRO
IPC: G11B5/127
Filed: 1988-07-30
Abstract: PURPOSE:To obtain the magnetic head having a gap where there are no deposits by subjecting the butt surfaces of magnetic core blocks to specular finishing then to a heat treatment, forming a gap layer to the gap butt surfaces and butting the magnetic core blocks against each other, then joining the blocks by low-melting glass. CONSTITUTION:Both of the C-shaped magnetic core block 1 and I-shaped magnetic core block 2 are heat treated before the thin film of the glass 3 forming the gap is formed; thereafter, the thin film of the glass is formed and further the two core blocks 1 and 2 are butted against each other and are joined under pressurization at a high temp. In other words, the butt surfaces of the magnetic core blocks 1, 2 consisting of ferrite are subjected to the specular finishing and are then subjected to the heat treatment. The oxygen O2 existing in the work hardened layer formed at the time of the specular finishing is removed and thereafter, the gap part is formed on the butt surfaces; further, the magnetic core blocks are butted against each other and are joined in a furnace where the oxygen concn. is low. A hematite layer (deposit) is, therefore, not formed by the oxygen contained in the work hardened layer. The deterioration in appearance of the gap of the magnetic head by the hematite layer is obviated in this way.
