摘要:
An electron probe microanalyzer equipped with a wavelength-dispersive x-ray spectrometer and also with an energy-dispersive x-ray spectrometer. X-rays emanating from the same sample region are detected by these two spectrometers, and spectra are created from the detected x-rays. Cursors which can be moved at will are superimposed on the spectra. One of the cursors is moved in relation to the other. That is, when one cursor is moved into the position of a desired wavelength or energy, the other is moved into the position of the corresponding energy or wavelength. The use of the cursors enables one to precisely and easily find the existence of a certain element in the sample region from the spectra obtained by the two x-ray spectrometers.
摘要:
A display for an x-ray microanalyzer including a wavelength-dispersive x-ray spectrometer and an energy-dispersive x-ray spectrometer for producing two kinds of spectra from the same region on a specimen. A circuit enables markers to be superimposed on the spectra to indicates some wavelengths and energies of the characteristic x-ray emanating from a chemical element selected by the operator. The markers faciliatate precisely confirming the existence of the element in the region, based on the two kinds of spectra.
摘要:
A surface analysis instrument such as an electron probe microanalyzer. The instrument makes surface analyses of different regions on a sample and displays images of the regions according to the obtained information at different positions on the viewing screen of a display unit. The instrument creates a mixed histogram of the regions from the information about the regions. A level assortment is carried out according to the mixed histogram. Information about the level assortment is stored in a memory. Colors are assigned to images of the different regions according to the information about the level assortment. The images are displayed at different positions on the viewing screen.

The disclosed embodiments relate to a stator and manufacturing method of the stator in which the coil conducts of the stator have three phases (a U phase, V phase, and W phase), which are arranged in a distributed winding form in a plurality of slots of a stator core. The coil conductors of the three phases each include a slot conductor portion that is disposed in the slot, and a pair of coil end conductor portions disposed on both axial sides of the stator core to connect the slot conductor portions disposed in the different slots. The stator also includes a first side transition wire portion in each phase that is disposed further toward a radial inner side than an inner peripheral end surface of a tooth provided on each circumferential side of the slot so as to overlap another first side transition wire portions in the axial direction.
摘要:
A method of manufacturing a semiconductor device that includes a first and second device regions on a substrate. The method includes the steps of forming an insulation layer on the substrate, laminating a first semiconductor layer having a plane orientation different from the surface of the substrate on the insulation layer and exposing the substrate by removing the insulation layer and the first semiconductor layer from the second device region. A second semiconductor layer having the same plane orientation as the substrate and that is made of a strained layer is formed by epitaxial growth on the exposed substrate in the second device region.

A rocking substrate 31 provided with a porous unit 41 is supported by a platform 21 by means of a spherical bearing. Furthermore, air is provided between the platform 21 and the rocking substrate 31 to allow the rocking substrate 31 and the porous unit 41 to rock along a spherical surface. This rocking allows the top surface 12a of an improved levitation unit 12 to tilt freely. When a wavy glass substrate is placed on the levitation device, the top surface 12a of the improved levitation unit 12 tilts, tracing the tilt of the substrate. Jetting air out in this state levitates the substrate, with its top surface 12a in the horizontal state, and allows the levitational force to be reliably applied to the substrate.

A piezoelectric gas lighter includes a lighter body. The fuel gas in the lighter body is supplied to a nozzle through a valve mechanism which is opened and closed by an actuator lever and a piezoelectric unit ignites the fuel gas discharged from the nozzle. A depression member actuates the actuator lever and the piezoelectric unit to open the valve mechanism and ignite the fuel gas discharged from the nozzle in response to depression of the depression controller. The depression member includes a control cap operatively connected to a piezoelectric unit, a stopper member which is movable between a locking position where the control cap is prevented from being depressed and a releasing position where the control cap is permitted to be depressed and an urging member which urges the stopper member to the locking position. The stopper member is provided with a pair of sliding portions extending back and forth on opposite sides of the control cap and the sliding portions are slidably supported by the control cap so that the stopper member is movable downward together with the control cap and movable between the locking position and the releasing position. The urging member includes a pair of resilient pieces provided on opposite sides of the control cap so that they are engaged with the sliding portions of the stopper member to urge the stopper member to the locking position and the stopper member is moved to the releasing position by urging the stopper member toward the control cap.
