Abstract: PURPOSE:To improve mass production by arranging a Faraday rotor, an optically rotatory element (or quarter-wave plate) having reciprocity to rotate the plane of polarization 45 deg. and an analyzer (or polarizer) in this order in such a manner that the planes of transmission polarization of the polarizer and the analyzer are aligned to each other. CONSTITUTION:The absorption type polarizer 1, the Faraday rotor 2 of a YIG crystal, the quartz crystal quarter-wave length plate 3, the absorption type polarizer 4 and a magnet 5 of a cylindrical shape are arranged in prescribed positions and are assembled in an inert gas 6 using gaseous argon or gaseous nitrogen for heat insulation. This magnet 5 impresses saturation magnetization to the Faraday rotor 2. As a result, the Faraday rotor 2 rotates the plane of the transmission polarization 45 deg.. The quartz crystal quarter-wave length plate 3 is so arranged that the light (forward direction) from the Faraday rotor 2 rotates the plane of transmission polarization 45 deg. in a direction opposite from the Faraday rotation. The planes of the transmission polarization of the absorption type polarizer 1 and the Faraday rotor 4 are aligned.

IPC: G11B5/455
Filed: 1991-09-21
Abstract: PURPOSE:To highly precisely measure head fitting positions against a reference based on the image output of a one-dimensional sensor having a prescribed angle relation for a head gap. CONSTITUTION:The one-dimensional sensor 18 which inclines by a prescribed angle against the gap 36 of the magnetic heads 3A and 3B image-picks up the tape sliding surface of the magnetic heads. Moving means (X-Y tables 10A and 10B) which move the one-dimensional sensor 18 in a tape sliding direction are provided. A head gap position signal is detected by discriminating it from a pseudo signal such as noise based on image output in first and second different cross positions where the one-dimensional sensor 18 and the head gap cross, and angle information of the head gap against the one-dimensional sensor. Then, head position information against a reference position is obtained based on level information or position information on the detected gap position signal.

IPC: H04B10/50
Filed: 1993-10-28
Abstract: PURPOSE:To provide the driving circuit for light emitting elements which can drives a light emitting element at a high speed and facilitates light emission output control. CONSTITUTION:When a transistor(TR) QA1 turns off to stop supplying a current to the light emitting element D1, a TR QA3 connected to the light emitting element D1 in parallel turns on and the terminals of the light emitting element D1 is short-circuited. Therefore, when the light emitting element D1 lights out, electric charges accumulated in the parasitic capacitance of the light emitting element D1 are rapidly discharged. Further, when the TR QA1 turns on to start supplying the current to the light emitting element D1, a TR QA1 turns on at the same time and a current signal D having a peak at the time of its rise flows to the light emitting element D1. Therefore, when the light emitting element D1 illuminates, the capacitance C1 parasitic to the light emitting element D1 is speedily charged with the peak component at the time of the rise of the current signal D.
