An image forming apparatus according to the present invention includes: a fixing part having a heater; a control part controlling ON/OFF of power distribution to the heater; a power source part generating a voltage for driving the control part; a main switch for turning ON/OFF power supply from outside to the power source part; and an interrupt signal generation part generating a periodical interrupt signal. The control part, based on the interrupt signal, controls ON/OFF of the power distribution to the heater, turns OFF power supply to the heater upon passage of predetermined time since disappearance of the interrupt signal, and judges that an error has occurred, when the control part is still driving after passage of driving stop time from when the main switch is turned OFF to when the control part stops its driving since the disappearance of the interrupt signal.

A technique is provided which can exactly recognize a chip to be picked up when picking up the chip from a wafer sheet in a process of die bonding a thin chip. A camera is coupled to one end of a lens barrel, an objective lens is attached to an opposite end of the lens barrel, and an image of a main surface of a chip is photographed through the objective lens. A surface-emitting lighting unit, a diffusing plate and a half mirror are internally provided between the lens barrel and the chip. Further, another lens barrel having a coaxial drop lighting function of radiating light to the main surface of the chip along the same optical axis as that of the camera is disposed.

A technique with which die bonding can be carried out without forming a void in a bond area is provided. A vacuum supply line that connects to a vacuum chuck hole formed in the bottom face of a vacuuming collet and supplies the vacuuming collet with reduced pressure for vacuum chucking a chip is constructed of two systems. That is, the vacuum supply line is so structured that a first pipe and a second pipe connect to the vacuuming collet. The first pipe supplies the vacuuming collet with a vacuum that provides suction force when a chip is unstuck from a dicing tape and transported to a mounting position on a wiring substrate. The second pipe supplies the vacuuming collet with a vacuum that provides suction force when a chip is mounted over a wiring substrate. The intensity of the vacuum (suction force) supplied to the vacuuming collet is controlled by opening or closing valves respectively installed in the pipes.

The present invention provides a time recorder with a card feed rate adjustment function making it possible to print data for arrival and departure times to and from a job side at a correct position within a print column by adjusting a feed rate for a time card according to extension or shrinkage of the time card or characteristics of the time card such as a printing state within the print column. An adjustment value is computed by reading a start point and an end point printed on a time card TA or TB inserted into the time recorder with the mark sensors 10, 11 and counting a feed rate for the time card TA or TB from the start point to the end point with the encoder sensor 12, and a feed rate for the car is adjusted according to the computed adjustment value.

There is disclosed a heat resistant cloth for fire fighting. At least an inner surface of a fluororesin film is subjected to plasma discharge treatment to form a treated surface. A vacuum-deposition film made of a bright metal such as aluminum is formed on the treated surface of the fluororesin film without use of a primer. The vacuum-deposition film on the treated surface is bonded to an outer surface of a substrate fabric through use of a silicone rubber adhesive in order to form a heat-reflecting layer on the outer surface of the substrate fabric. Since no primer coating layer is used, the heat reflecting layer can prevent a decrease in brightness, which would otherwise occur due to cracks generated in the primer coating layer. Thus, a decrease in heat reflectivity at high temperature is prevented. Since no flammable synthetic resin layer is used at the surface of the heat reflecting layer, flame resistance can be improved.

A die bonder and a bonding method are disclosed which make it possible to provide high-quality products, particularly even if a die is rotated through predetermined degrees relative to an already-bonded die and then laminated.In the die bonder and bonding method in which a die is picked up from a wafer by a pick-up head which then places the die on an alignment stage, and the die is picked up from the alignment stage by a bonding head which then bond the die onto a substrate or an already-bonded die, a posture of the die is rotated through predetermined degrees on a plane parallel to a plane on which the bonding is performed, before the bonding head picks up the die from the alignment stage.
