摘要:
A method of producing metal particles, including the steps of forming a membrane of a polymer or oligomer which has, at the terminals of its molecule and/or in the side chains thereof, at least one functional group selected from cyano, amino and thiol groups, and depositing a metal on the membrane through vapor deposition so that the membrane has particles of the metal and/or its oxide dispersed therein.

Controlling a deflection of an irradiation direction of a vehicle lamp based on a detected steering angle includes calculating a target angle of the irradiation direction of the vehicle lamp based on the steering angle and calculating a difference angle between the target angle and a current deflection angle of the irradiation direction of the vehicle lamp. A new deflection angle is calculated and includes setting the new deflection angle to the target angle if the difference angle is equal to or smaller than a given limit angle, and setting the new deflection angle to an angle obtained by adding or subtracting the limit angle to or from the current deflection angle if the difference angle is larger than the given limit angle. Deflection of the irradiation direction of the lamp is controlled based on the deflection angle.

An emitting direction control apparatus for a lamp is provided with: a driver for deflecting an emitting direction for a lamp; and a controller that control the driver to perform a deflection. The controller includes an initialization function, for setting, at an initial position, a stepping motor that serves as a driving source for the driver. The initialization function detects a first current positional angle for the stepping motor; when the first current positional angle is greater than a reference angle, rotates the stepping motor in a bumping direction at a high speed until the reference angle is reached; after the reference angle has been reached, rotates the stepping motor to a bumped position an initial number of steps at a low speed; and after the bumped position has been reached, rotates the stepping motor in the reverse direction a predetermined number of steps and sets the stepping motor in the initial position.

At the time when the control signal line of a printer controller is connected to the input terminal of a three-state buffer, the control signal line is connected also to the D input terminal of the flip-flop that operates according to the FFCK clock. The control signal of Q output signal of the flip-flop is inputted into the AND gate circuit, and the output signal of the gate is inputted into the control terminal of three-state buffer. Accordingly, by synchronizing the signal to the place where the level of control signal line starts, the level of data signal line changes from level 1 to the level of output. After that, waveform rounding that is generated at the time of releasing the signal line is reduced to enable higher communication speed.

The present invention provides a magnetic head which has a magnetic circuit of a reduced size to cope with a high density recording and a preferable recording/reproduction characteristic. The magnetic head according to the present invention has at least partially a non-magnetic body 7 and includes: a magnetic circuit block 6 constituted by magnetic bodies arranged to oppose each other via the non-magnetic body 7; and a magnetic tunnel element 1 attached to this magnetic circuit block 6 and having a first magnetic layer 2 and a second magnetic layer 4 which are layered via an insulation layer 3. In this magnetic head, a magnetic field from a magnetic recording medium is induced to the magnetic circuit block and the induced magnetic field changes a relative angle of magnetization of the first magnetic layer 2 and/or the second magnetic layer 4 with the other magnetic layer of the magnetic tunnel element 1.
摘要:
A layer is provided for bonding a conductive plating to a substrate which substrate normally does not provide firm bonding of plating directly thereto. The bonding layer forms a matrix in which are dispersed ultrafine metal particles. The bonding layer is formed in situ on the substrate surface with the metal particles being maintained unaggregated in the matrix as it is formed on the surface. Plating subsequently formed on the outer surface of the bonding layer is effectively firmly bonded to the substrate through the intermediary of the matrix and metal particles distributed therein. The bonding layer includes a fixative formed of an organic compound including a metal and an organic solvent. The bonding layer may further include a film strengthener.
