    摘要: The voltage of a detection resistor connected to the drain of a low-side switching device is normally a negative voltage, but a positive voltage appears when a countercurrent occurs in an abnormal state. A current comparator monitors the voltage of the detection resistor, transmits high output to an AND circuit whole the voltage of the detection resistor is a negative voltage to maintain the output voltage of the current comparator in a low state when an output signal of a driver can be transmitted to the low-side switching device, and allows the output voltage of the current comparator in a low state when the voltage of the detection resistor becomes a positive voltage, thereby forcibly turning off the low-side switching device.

    摘要: A current negative-feedback circuit comprises a current detection unit and a sawtooth-shaped waveform generation unit. The current detection unit comprises a first P-ch MOSFET Q2 and a second P-ch MOSFET Q3 which constitute a current mirror circuit, a current adjustment resistor R4, a current detection resistor R1, and a constant current source I1. The current mirror circuit outputs current almost proportional to the charge current of an inductance via a switching device or outputs a current which is the quadratic function of the charge current of an inductance. The sawtooth-shaped waveform generation means adds the constant charge current of the constant current source I2 and the current output from the current mirror circuit, charges the capacitor C1, and generates a sawtooth-shaped waveform.

    摘要: A package for dispensing a pourable product has a first hollow body member, a second hollow body member, and a pouring spout. The first hollow body member has a first exterior surface and opposite therefrom a first interior surface which defines a first internal volume. The second hollow body member has a second exterior surface, a second interior surface, a flow-regulating passage, and a dispensing passage separate from the flow-regulating passage. The second exterior surface defines a second external volume smaller than the first internal volume. Opposite the second exterior surface, the second hollow interior surface defines a second internal volume. A fastener is formed on the second interior surface. The pouring spout is operatively connected to the dispensing passage.

    摘要: A distance measuring apparatus for automatically measuring a distance from a reference point to a subject of interest, such as a subject to be photographed, is provided. The present apparatus includes a position sensitive detector having a photoelectric surface defined between two extreme points. Thus, when a light pulse emitted from the apparatus is reflected by the subject and impinges upon the photoelectric surrface, there is produced a pair of current signals, which are then processed to obtain a distance signal indicating the distance to be measured. Thus, the present apparatus can provide a highly accurate measurement.
