摘要： A method and system for managing the overall life cycle of a product from its manufacture to its destruction or recycling. To the product is affixed a storage medium storing a product identifier uniquely identifying the product and information about the parts that are contained in the product. At each site that the product passes through during its life cycle, product life cycle information is recorded in the storage medium affixed to the product. When the product is to be destroyed or recycled, the information stored in the recording medium is used to determine the method for destroying or recycling. The product is then destroyed or recycled according to this method.

摘要： A disk drive system comprises a magnetic disk apparatus which accurately positions read/write means for reading data from and writing data on tracks on the data surface of a rotary disk on a predetermined track on the disk on the basis of servo data written in the servo area formed on the data surface, and a disk controller which controls the mode of operation of the disk apparatus. Index signals respectively indicating the start and end of the servo area are generated on the basis of the result of detection of the angular phase of the disk. The mode of operation of the magnetic disk apparatus is discriminated on the basis of a write control signal provided by the disk controller. The index signals respectively indicating the start and end of the servo area are sent to the disk controller when the mode of operation is track format write mode, while the index signal indicating the end of the servo area is sent to the disk controller when the mode of operation is other than the track format write mode.

摘要： It takes a comparatively long time (T s 1 ) for a rotor of a stepping motor (100) to be positioned at the next target stop position (target angular position) and stopped there. This time is the settling time. Before the rotor passes through the next target angular position and begins to oscillate, necessary Icontrol means is taken to reduce the width of the oscillation for the purpose of shortening the settling time. The phase excitation on each winding (φ 1 , φ 2 ) of the stepping motor is usually changed over successively until the target angular position is reached. When the stepping motor has approached the target angular position, the changeover of phase excitation is gradually conducted. As a result, the width of the above described oscillation is reduced and hence the settling time is shortened.

摘要： An AC motor (12) such as an induction motor or a synchronous motor is driven by a PWM inverter circuit (11). Power switching elements (Up, U N , Vp, V N , Wp, W N ) of the inverter circuit are ignited by PWM pulses resulting from comparision of a carrier wave signal with a sine wave modulation signal at a frequency proportional to a frequency setting signal (f R ) so as to control the inverter circuit. A current polarity detector (14) detects positive and negative components (I A , I B ) of a DC current I D ) flowing in the input side of the inverter circuit. The frequency setting signal is so corrected as to be decreased when only the positive current component flows in excess of one period of the carrier wave signal or increased when only the negative current component flows in excess of the one period.

摘要： Method and apparatus for detecting vertical and horizontal deformations of leads (20) of a semiconductor device (11) by illuminating the leads with a planar light beam (14) and determining relative positions (22a, 22b) of the planar light beam on the leads on the basis of distribution of light rays reflected from the leads. Different lead deformations can be detected with one and the same mechanism within a short time. By applying the invention to a semiconductor device mounting apparatus, a single detector can be employed in common both for the detection of the semiconductor device position and the detection of reflections of the planar beam.
