Electrode styli 7, 7 connected to the output terminals of a DC power source (for example, DC 150V) are respectively brought into contact with the pad 25 and the magnetic pole terminal part 26. A DC voltage is impressed to the magnetic pole terminal (upper magnetic pole layer) and the pad (coil layers 18, 20) via both electrode styli, and whether large current flows or not is detected via a current detecting gage 8, by which the presence or absence of the desired isolation voltage is inspected. Protective layers are formed on the respectively layers and the prescribed parts of the substrate are cut after the inspection, by which the thin-film magnetic head is produced.

Filed: 1987-06-10
Abstract: PURPOSE:To make the rotational braking force of a damper adjustable by changing the pressure applied to the polyisobutylene or the like which is used as the elastic fluid for a rotational multiplate type damper. CONSTITUTION:A rotational multiplate type damper is constituted by placing alternately in the vertical direction through a movable shaft 2 a movable plate 6 which is rotatable together with the movable shaft 2, and a stationary plate 7, which does not follow the rotation, as well as keeping an elastic fluid A of polyisobutylene or the like in a casing 1.

Title: Ventilating roof
Inventor: KIMURA TOKUJI
IPC: F24F11/76
Filed: 1981-09-14
Abstract: PURPOSE:To automate the regulation of a temperature of an attic by a constitution wherein the top of the ridge of the roof is opened to vent air and is provided with a bimetal type opening amount regulating panel having a C-shaped section in which the radius of curvature thereof is decreased as the temperature thereof is risen while the opening is covered by a ventilating ridge equipped with venting galleries. CONSTITUTION:When the temperature is risen in summer, the radius of curvature of the opening amount regulating panel 5 is decreased and the opening amount regulating panel 5 opens the venting opening 2 thereof widely in up- and-down direction. Accordingly, hot air behind the roof is discharged out of the venting opening 2 through the venting galleries 3 of the vetilating ridge 4 to reduce the temperature behind the roof. On the contrary, the radius of curvature of the opening amount regulating panel 5 is increased reversely in winter and the opening amount of the venting opening 2 is decreased. Accordingly, the hot air behind the roof is not allowed to escape and the reduction of the temperature behind the roof may be prevented. According to this constitution, the automatic regulation of the temperature behind the roof may be effected.
