摘要:
[Object] To provide a heater energization control apparatus which can detect that a heater has been exchanged.[Means for Solution] When an engine is stopped, a microcomputer of a GCU enters a power save mode. When the microcomputer returns to a normal mode in response to an interruption signal periodically generated from an interruption timer, the microcomputer supplies electricity to a heating resistor for a short time and obtains its resistance (S19). When the resistance is greater than a first reference value, the microcomputer determines that a glow plug is removed from the engine; that is, the glow plug is being exchanged (S29). The microcomputer sets an exchange flag to “1” (S30), and performs calibration for the heating resistor of a new glow plug after the engine is operated next time (S35). Further, since the resistance of the heating resistor changes (increases) with deterioration of the heating resistor with time, the acquired resistance may be stored. When the current resistance becomes smaller than the past resistance, the microcomputer determines that the glow plug has been exchanged.

A robotic system and process for automatically orienting/positioning a vehicle panel prior to its installation to a vehicle. The panel is first moved by the robot from a temporary storage position to an alignment fixture that acts to initially define the orientation/position of the panel in two directions. The robot subsequently contacts the panel such that the panel is pushed against a position stop that defines the position of the panel in a third direction. With the panel properly oriented/positioned, the robot removes the panel from the alignment fixture and transfers it to the vehicle for installation. Panels of dissimilar size and/or shape may be installed using the same system and process.

A system and method for welding projection weld nuts to a work piece. The system and method of the present invention generally makes use of a fixtured work piece having one or more projection weld nuts associated therewith. A resistance welding robot is used to weld the projection weld nuts to the work piece. The welding robot typically has weld electrodes therewith, through which electric welding current is passed to the projection weld nut(s) and the work piece. A first and second contacting electrode is used to transfer electric current from the welding robot electrodes to the projection weld nut(s) and work piece.

An optical disc 1 has formed in an area inside the inner circumference of an information recording area 2 formed thereon concentric or spiral continuous or discontinuous recesses 4a at a lager pitch than the track pitch in the information recording area 2. The optical disc is manufactured by installing a hub 5 substantially in the center of an optical disc substrate with reference to the recesses 4a by positioning the hub 5 with respect to the optical disc substrate. A stamper for manufacturing the optical disc substrates is produced by exposing a photoresist layer 11 to a laser beam by turning on and off the laser beam while rotating a glass substrate 10 having the photoresist layer 11 applied thereon and scanning the laser beam radially of the glass substrate 10.
