摘要:
The control property of an onboard device is changeable by using an external control unit, and the data from the external control unit is authenticated. An onboard gateway unit is provided with a verification code generator for generating a security key, and an external control unit is provided with an application control unit for generating a security key. When the external control unit is connected, a main control logic unit of the gateway unit compares the two keys, and when the keys are verified, the control by the external control unit using an application program is enabled. The onboard device control unit can be easily connected to the external control unit. As the control of the device control unit by an external control signal is enabled only when verified, an unauthorized access can be prohibited, and the onboard deice can be controlled only by an authorized control signal.

A print circuit board having a conductive pattern on the insulating film layer of the substrate for print circuit board, and methods of manufacturing the substrate and the print circuit board. One of typical methods of manufacturing the substrate for print circuit board comprises steps of applying an annealing separator mainly consisting of MgO on the steel sheet and annealing it to form a forsterite film layer, applying and baking a coating solution mainly consisting of the phosphate and colloidal silica onto the forsterite film layer to form an insulating film layer. The print circuit board is obtained by bonding the conductive pattern to the insulating film layer and annealing at a temperature range of not lower than 300.degree. C. but lower than 1,050.degree. C.

A double roll type method and apparatus for producing a thin metallic sheet by pouring a molten metal of a desired composition into a kissing region between two cooling rolls rotating in opposite directions, and rapidly cooling and solidifying the molten metal while it passes through the kissing region. The thin sheet which has come out of the kissing region is forcibly deflected by gas from a gas applying head and by a pair of pinch rolls so as to make close contact with one of the two cooling rolls over a predetermined region in the circumferential direction of the roll.

A vehicular seatbelt device whereby slack in a lap belt is sufficiently eliminated according to a traveling state of a vehicle, and a comfortable ride for a vehicle occupant is maintained. A seatbelt device comprises a belt retraction part and an actuator for driving the belt retraction part. The belt retraction part pulls part of a belt in a direction opposite the direction in which the belt is wound up by a belt reel so as to restrain the vehicle occupant. A controller includes a plurality of pre-set control modes for controlling a motor and the actuator in accordance with the traveling state of the vehicle, and selects and implements one control mode corresponding to the traveling state from among the plurality of control modes. The control modes include a mode for drivably controlling both the motor and the actuator, a mode for drivably controlling only the motor, and a mode for drivably controlling only the actuator.

A method for obtaining grain-oriented silicon steel sheet with a very high magnetic flux density and a very low core loss by setting specific conditions for the decarburization and primary recrystallization annealing step within the series of steps performed for the manufacture of the grain-oriented silicon steel sheet.
