Title: Magnetic head
Inventor: OTOGAWA TAKAO
IPC: G11B5/147
Filed: 1983-10-14
Abstract: PURPOSE:To prevent the occurrence of tape squeaking for a long time by constituting a magnetic head so that a fixing material near a sliding face contacts a specific amount of an organic lubricant and an organic lubricant is allowed to permeate the fixing material facing the sliding face and parts between thin plates of a magnetic core from the side of the sliding face. CONSTITUTION:If a fixing material 6 is allowed to contact 0.1-3.0wt% organic lubricant and an organic lubricant is allowed to permeate the fixing material 6 facing an aperture part 3 of a sliding face 2 and parts between thin plates of magnetic cores 4A-4D from the side of the sliding face 2, supply of organic lubricants is stabilized for a long time. If organic lubricant content is smaller than 0.1wt%, supply of organic lubricants to the sliding face 2 is too small or is not uniform; and if organic lubricant content is larger than 3.0wt%, characteristics of the fixing material are degraded, and supply of organic lubricants is unstable, and in any case, characteristics of the magnetic head are degraded, and prevention of tape squeaking is not stable for a long time.

Filed: 1993-08-02
Abstract: PURPOSE:To provide a stable power source in which a reference voltage is generated by amplifying the difference of threshold values, and reference potential generating circuit in which dependency on temperature can be substantially reduced. CONSTITUTION:The difference of the threshold values of transistors Q1 and Q2 is converted into currents I1 by a resistor R10, currents I2 are allowed to flow to a current mirror circuit, and the currents I2 are converted into a voltage again by a resistor R20. Then, a potential which doesn't depend on a power supply voltage and temperature can be generated for voltage VR. Even when the difference of the threshold values is small, the difference can be sufficiently amplified, so that it is not necessary to control and form a transistor in which the absolute value of the threshold value is large, and it is possible to decrease diffusing processes. Also, current consumption can be suppressed to several muA.
