Filed: 1984-08-02
Abstract: PURPOSE:To detect a surface defect of a magnetic disc accurately, by making the core width of a testing head for scanning over the magnetic disc less than the core width of a servo head or the azimuth thereof exceed a specified value. CONSTITUTION:When a servo head is used to detect a surface defect of individual magnetic disc single plates of a servo type magnetic disc device which perform a position control of a W/R head, the core width W of a testing head which detects ba defect scanning over a track 1 of a magnetic disc shall be made less than a quater as much as the core width of the servo head considering the width W of a clutch flaw 3 to be detected. an azimuth is given beforehand to tilt a core 2 of the testing head by an angle theta with respect to the radial direction of the track. This makes the detection width D of the clutch flaw 3 to be detected larger than the actual width (w) with respect to the core width W thereby facilitating the detection of a flaw. The azimuth of the head is preferably more than 20 deg..

Abstract: PURPOSE:To generate an output voltage independent of a power voltage and to attain the bias circuit of a low output impedance by providing two voltage generation parts of a reference voltage generation part and the source follower output voltage generation part of a low impedance. CONSTITUTION:A current flowing in the reference voltage generation part is decided by an N transistor 1 and a resistor 3, and the current independent of the power voltage is shifted to the output voltage generation part by current mirrors 5 and 6. Then, the output voltage generation part feeds back the output voltage, converts a current which a current mirror 7 shifts into the voltage by an N transistor 8 and a resistor 11, both of which control a voltage value supplied to a source follower, and outputs the converted voltage value of the source follower. Namely, the source follower generates the output voltage, the output voltage is fed back and the voltage value supplied to the source follower is changed. Thus, the output of the low impedance can be obtained and the current can be shifted in the current mirror 7, whereby the output voltage independent of the power voltage can be obtained.

IPC: B41M5/00
Filed: 1984-08-03
Abstract: PURPOSE:To obtain a light pervious recording material for ink jet recording excellent in ink receptivity and imparting excellent sharpness to a recording image, by providing an ink holding layer and an ink pervious layer and bringing the ratio of the thickness of the ink pervious layer and the particle size of the liquid droplet of a recording solution to a specific range. CONSTITUTION:The ratio of the thickness (t) of an ink pervious layer and the diameter (d) of the liquid droplet of a recording solution is set to 0.01<=t/d<=0.1. Because the diameter (d) of the liquid droplet of a usual ink jet recording solution is about 10-100mum, the thickness (t) of the ink pervious layer is 10mum or less, pref., about 0.1-5mum. However, if the ink pervious layer is too thin to the diameter of the liquid droplet of the recording layer, the recording part of the recording material is protruded in a lens like shape and a long time is required in flattening said recorded part and the straight advance property of light at the recording part is injured, especially, in the case of a light pervious recording material to generate inconvenience from the aspect of obaservation. If the thickness of the ink pervious layer is excessively large to the diameter of the liquid droplet of the recording solution, the time required in fixing ink becomes too long resulting in inconvenience.
