摘要： A winding is wound directly on the magnetic head core formed of a single crystal of Mn—Zn ferrite. The diameter is 20-30 &mgr;m. A high-saturated magnetic flux density material (iron) having a magnetic flux density which is more than 1.3 T covers walls of the magnetic gap using sputtering. A slider including the magnetic head comprises ceramic including titanium calcium. The magnetic head is adhered to the slider with a low melting point glass. In a magnetic recording apparatus including the above-mentioned magnetic head, the slider includes air bearing surface trains arranged in the driving direction of the magnetic recording medium on a contact surface of the slider. Each bearing surface train includes protruding portions and a hollow portion direction. The hollow portion escapes the air between the protruding portion and the recording medium. The head is evacuated from the magnetic recording medium.

摘要： According to the present invention, a channel protection film is formed a little smaller in area than the gate electrode formed of a shielding metal film. A semiconductor thin film is formed such that the thickness is set not less than 200 Å and less than 400 Å. A distance A between the edge of the gate electrode in the channel length direction and the edge of the channel protection film is set around 0.2-1.2 &mgr;m, and a distance B between the edge of the gate electrode in the channel width direction and the edge of the channel protection film is set around 1-2 &mgr;m. With this constitution, the leak current of the thin film transistor due to the light irradiation can be reduced.

摘要： An outboard motor has various electrical components mounted on a front side of the crankcase chamber. The crankcase chamber is connected by an electrical line to a negative terminal of a battery in an associated watercraft in order to ground the crankcase chamber. Thus, the electrical components are easily grounded by being connected to the crankcase chamber. An intake silencer of the engine induction system is positioned adjacent the crankcase chamber and at least one of the electrical components is disposed between the silencer and the crankcase member. An oil filter mount is also disposed on the front side of the crankcase chamber. The mount is adapted so that the oil filter can be installed thereon and is tilted along an inclined axis.

摘要： A plate spring is provided on a back surface of a shutter of a cartridge. When the shutter is closed, the plate spring presses a disk in a cartridge case against an inner wall surface of a lower case so that the disk is immovable in the case. When the shutter is open, the plate spring is retracted into a space between an inner surface of the shutter and a surface of an upper case. The disk is supported immovably and uniformly in the cartridge. Therefore, deformation such as warpage of the disk hardly occurs. Even when the cartridge is stored in any posture, it is possible to avoid deformation such as warpage and flexure of the disk in the cartridge during the storage.

摘要： A magneto-optical information recording/reproducing apparatus in which a magneto-optical information recording medium at least including a first magnetic film having perpendicular magnetic anisotropy, and a second magnetic film to which information recorded on the first magnetic film is transferred by irradiation of a laser beam, is used so that a readout laser beam is irradiated onto the second magnetic film to thereby readout the information transferred to the second magnetic film. The apparatus includes a 2-split detection circuit for receiving the readout laser beam reflected from the second magnetic film of the recording medium, and a subtraction circuit in which output signals of the two detection elements of the 2-split detection circuit are subtracted from each other to generate a differential signal. The apparatus further comprises a circuit for making a spot of the laser beam jump one track before readout of the information from the magneto-optical information recording medium, a positive/negative balance correction circuit for detecting an amplitude ratio between positive and negative side amplitudes in a track jump signal generated in the differential signal from the subtraction circuit in response to the track jump to thereby output a correction signal in accordance with the amplitude ratio, and an addition circuit for adding the correction signal to the differential signal to thereby generate a tracking error signal for tracking control used in readout of the magneto-optical information from the magneto-optical information recording medium.

摘要： An outboard motor having a multi-cylinder four-cycle, internal combustion engine as a power plant. An improved crankcase ventilating system is provided wherein the crankcase ventilating gases follow a circuitous path through the crankcase chamber, camshaft chambers and then to the intake system through an extended conduit passing over the exhaust manifold so as to reduce the emissions of hydrocarbons. The intake system is designed to preclude uneven distribution of the ventilating gases. The intake system also is comprised of a plenum device, a plurality of runners and throttle bodies and an intake manifold that are attached as a unit to the rest of the engine body. Portions of this unit are formed from a synthetic resin.

摘要： An outboard motor cooling system wherein the coolant is circulated through the various cooling jackets so that it first flows into proximity with at least a portion of the exhaust system cooling jacket and then into the cooling jackets of the main engine body that cool the cylinder bore and combustion chamber. Sacrificial anodes are positioned both in the main engine body cooling jacket and in the exhaust system cooling jacket. In addition, a temperature sensor is positioned in a low portion of the cooling jacket and where the water has passed through the exhaust cooling jacket and before it enters the main engine body cooling jacket so as to provide accurate temperature indication while protecting the temperature sensor from excess temperature conditions particularly after engine shut off.
