Abstract: The present method aims at preventing breakdown by selecting conditions for preventing the occurrence of voids via analysis. According to the present method, a database related to the time variation of amount of generated gas or number of moles when a solid member is heated is experimentally formulated in advance, and the amount of generated gas from the member and the specific heat ratio of gases are entered for analysis in order to predict via analysis the generation of voids within the resin material when the solid member is heated, to thereby select conditions for preventing voids.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An irradiating direction control apparatus includes an identifier for determining a difference in a load state of the vehicle corresponding to a passenger or carrying capacity. In an initialization performed to eliminate influence of an installation error of a vehicle height detector, a storage device stores data indicative of the installation error, based on a difference between a reference vehicle height corresponding to a load state of the vehicle determined by the identifier, and an actual vehicle height. Then, an irradiation controller obtains the attitude of the vehicle from vehicle height data corrected by using data stored in the storage device for vehicle height detection data, and controls a direction of an optical axis of irradiation of a lighting unit. The reference vehicle height value is changed corresponding to the vehicle load state in initialization, thereby reducing a control error related to the correction of the optical axis of irradiation.
