A time-of-flight mass spectrometry device, includes: a flight tube: a flight tube power supply that applies a voltage to the flight tube; and a noise reduction circuit that is connected to a flight tube voltage portion which lies between the flight tube and the flight tube power supply, wherein: the noise reduction circuit inverts and amplifies an input voltage from an input end of the noise reduction circuit, and feeds inverted and amplified voltage back to the flight tube voltage portion through an output end.

A pad forms a connection terminal suitable for coupling circuit elements integrated in a chip to circuits outside the chip itself. At least one inductor is provided for use in the reception/transmission of electromagnetic waves or for supplying the chip with power or both. The connection pad and inductor are combined in a structure which reduces overall occupied area. A magnetic containment structure surrounds the structure to contain a magnetic field of the inductor.

In the field of monitoring assemblies for gas tube switching devices which is operable in a plurality of different conducting modes, a monitoring assembly includes a monitoring module to distinguish in real time at least one conducting mode from the or each other conducting mode.

A display apparatus may include a substrate. The display apparatus may further include a display unit that includes an emission layer and is disposed on the substrate. The display apparatus may further include a protective layer that overlaps the display unit. The display apparatus may further include an organic layer that is disposed between the display unit and the protective layer. A top surface area of the organic layer may be equal to or less than a top surface area of the protective layer.

A gas switch includes an anode and a cathode spaced apart from the anode, wherein the cathode includes a conduction surface. The gas switch also includes a plurality of magnets arranged to generate a magnetic field that defines an annular path over a portion of the conduction surface at a radial distance from a switch axis, and a control grid positioned between the anode and the cathode. In operation, the control grid is arranged to establish a conducting plasma between the anode and the cathode, wherein, in the presence of the conducting plasma, a voltage drop between the anode and the cathode is less than 150 volts, and wherein the conducting plasma forms a cathode spot that circles the annular path.

A laser oscillator which can effectively remove scattered light by a simpler configuration. The laser oscillator comprises an output mirror and a rear mirror which are arranged facing each other and a discharge tube which is arranged between the output mirror and the rear mirror. The discharge tube has a first part which gets larger in inner diameter from a first end part in an axial direction facing the output mirror toward the rear mirror.
