Abstract: A bonding device equipped with a heating block for heating, for instance, a lead frame upon which bonding is performed including vacuum suction nozzles, which are installed above the heating block so as to lift the lead frame, and an air-cylinder, which raises and lowers the vacuum suction nozzles. The lead frame is lifted from the heating block by the vacuum suction nozzles, thus being prevented from being overly heated by the heating block.

Abstract: A device for inspecting a high loop of a wire bonded on, for instance, a lead frame including a frame carrying stand, which guides and supports a lead frame, and an inspection roller, which is installed directly above the frame carrying stand. The inspection roller has frame pressing parts made as an insulating part so as to press the side portions of the lead frame against the frame carrying stand 31; and the inspection roller further has a wire detection part made as conductive parts provided between the frame pressing ring. A step or height difference between the frame pressing parts and the wire detection part is formed so as to be equal to the upper-limit value of the maximum height of wire loops formed by the bonded wire, and high loops that exceed the upper-limit value are detected by way of an electric current that flows when the wire detection part contacts the bonded wire.

Abstract: A frequency dividing circuit/delay circuit is provided to generate a plurality of system clock signals according to the combination of frequency division and the delay based on a fast-speed basic clock signal to determine according to the address signal from a central processing unit (CPU) what the operating cycle of the slave is to select a system clock of optimum frequency or duty ratio for that slave. As a result, it becomes possible to shorten the time required for executing one cycle and, hence, to improve the performance of the whole personal computer system.

Abstract: A lead frame transporting device, which uses a pusher to feed a lead frame from a loader onto feeder rails and two optical sensors that are positioned above the both sides of the lead frame. The pusher feeds the lead frame a predetermined distance so that a first detecting point of the lead frame arrives under the sensors and then further feeds the lead frame so that a second detecting point of the lead frame arrives under the sensors. The sensors detects detecting holes of the lead frame at the first and second detecting points so that top or bottom and front or back of the lead frame is detected, so that improperly oriented lead frame is prevented from further being fed to a next step.

Abstract: A method of controlling an electric power steering apparatus includes the steps of determining a steering state in accordance with a detection value and a retrieval value of a motor terminal across voltage, and limiting a motor current when a steering wheel held state is determined as the steering state determination result and a motor current value in the steering wheel held state is a predetermined value or more.

Abstract: A probe is shifted at a distance where the probe and a material to be obsed are sufficiently far away from each other relative to the roughness of the material's surface. This method prevents the probe from colliding with the material's surface during the shift of the probe thereby enabling high speed shift of the probe. Further, a micro-drive mechanism for controlling tunnel currents may be stopped during the shift in order to minimize the drift which may be caused by heat generated inside the micro-drive mechanism. Therefore, it is particularly advantageous to apply this STM measuring method for high-speed and stable measurement of a very large surface area and a very rough surface.
