The present disclosure provides apparatuses and methods for color imaging and an increased field of view using spectrally encoded endoscopy techniques. At least one of the apparatuses includes an illumination unit having two or more spectrally dispersive gratings positioned, for example, on different planes or on the same plane but having grating vectors at an angle to each other such that bands of spectrally dispersed light propagating from the gratings propagate on different planes.

Endoscope probes and systems, and methods for use therewith

A noise reduction device capable of reducing noise over a wide frequency range and a detection apparatus including the same are provided. The noise reduction device includes a splitting unit configured to split pulsed light generated in a first period into three or more pulsed light beams, a delaying unit configured to provide the three or more pulsed light beams with different delay times, and a combining unit configured to combine the three or more pulsed light beams. Among the three or more pulsed light beams, two pulsed light beams whose delay times provided by the delaying unit are closest to each other are configured such that a difference between their delay times is equal to the first period.

Noise reduction device and detection apparatus including same

A Hall effect sensing apparatus for a moving object includes a moving magnetic member having concave and convex segments alternately at is periphery, a detector including a pair of Hall effect elements for converting a magnetic signal to an electric signal, a processing circuit for processing signals from the detector, a magnet for providing magnetic field to the Hall effect elements, and a yoke provided in close proximity to the magnet. The yoke has a smaller surface area than that of the magnet and is movably arranged so as to adjust detecting sensitivity of the sensing apparatus. Therefore, even though there are some variances of magnetic characteristics in the detector, the detecting sensitivity of the sensing apparatus can be adjusted to an optimum level by observing a signal outputted from the processing circuit.

Hall effect sensing apparatus for moving object having an adjustable

A film carrier is used for fabricating a semiconductor device, and comprises an insulating film and a plurality of conductive leads each extending on the insulating film and having a front side surface and a reverse side surface, and a bump is formed in each of the conductive leads and has a projecting surface projecting from the reverse side surface and a depressed surface defining a recess open to the front side surface, so that the bump has a dome-shaped configuration and is much liable to deform in a thermocompression bonding stage.

A high voltage generating circuit which includes a switching circuit for switching a DC input, a fly-back transformer whose input coil is driven by pulses delivered from the switching actuation of the switching actuation of the circuit, a rectifier circuit for rectifying the fly-back voltage generated in the output coil of the fly-back transformer, a capacitor for smoothing the rectified output, and a voltage stabilizing circuit. A diode is electrically connected to one terminal of the output coil of the fly-back transformer on the low-voltage side thereof as compared with the ground, the diode being so determined as to position in the forward direction to the direction of rectification. The voltage stabilizing circuit is formed by a voltage sensing circuit for sensing a DC high voltage output, comparing it with a reference voltage applied from a reference voltage source and generating an output of a result of comparison and a control circuit connected between the anode of the diode and the ground terminal. The control circuit is formed of a plurality of transistors including transistors controlled in response to the output from the voltage sensing circuit and a protective circuit for each of the transistors.
