A method and an apparatus for etching a semiconductor device which can perform an etching process without causing electrical and physical damages using a neutral beam generated by a simple apparatus. In the method, ions of an ion beam having a predetermined polarity are extracted from an ion source and accelerated. An accelerated ion beam is reflected by a reflector and neutralized. A substrate to be etched positioned in the path of the neutral beam in order to etch a special material layer on the substrate with the neutral beam. The gradient of the reflector is adjusted to control an angle of incidence of the ion beam incident on the reflector, and a voltage is applied to the reflector to control the path of an incident ion beam.

The socket unit is capable of driving the first and second insertion straps for further freely rotating relative to the housing. Using the above structure, the socket units are capable of adjusting directions thereof, thereby avoiding plugs from blocking insertion openings of adjacent socket units.

The present invention provides a technique for enabling even a person having no expert knowledge to adjust the direction of an optical axis easily with high precision. In a three-dimensional image processing apparatus having plural image capturing apparatuses, optical center of an image from an image capturing apparatus is stored for each of the image capturing apparatuses. A mark indicative of the optical center is superimposed on an image obtained from the image capturing apparatus. By referring to the mark for each of the image capturing apparatuses, the orientation of each of the image capturing apparatuses is adjusted so that all of the marks overlay on the same point on an object.

In an undulator for the generation of synchrotron radiation from a particle beam introduced into the undulator, two partial undulators are provided each comprising a conductor of superconductive material which, when a current is conducted therethrough, generates an undulator field that extends perpendicularly to the current flow, and the superconductive conductors are arranged in the individual partial undulators such that the undulator fields generated are not parallel, whereby, by controlling the energization of the two partial undulators, the polarization direction of the synchrotron radiation can be adjusted without mechanical movements.

A light-emitting diode (LED) device includes a substrate and an epitaxial layer which is disposed on a surface of the substrate. A depression is disposed to a sidewall of the LED device, and a reflective layer is disposed to on least one portion of the depression. By the reflective layer disposed to the depression of the sidewall of the LED device, the light loss caused by the interface of the substrate and the epitaxial layer can be reduced, the light absorbed by the substrate can be decreased, and the angle of the light exiting from the LED device can be adjusted. A manufacturing method of the LED device is also disclosed.

A method for adjusting the illumination direction angle of a strobe device includes the steps of: transmitting to a specific strobe device, a first signal related to the present illumination direction angle of the strobe device being adjusted; based on the first signal, causing the illumination direction angle of the specific strobe device to correspond to the illumination direction angle of the strobe device being adjusted; changing the illumination direction angle of the specific strobe device to a state desirable for the strobe device being adjusted; transmitting, to the strobe device being adjusted, the amount of further change in the illumination direction angle of the specific strobe device, as a second signal; and changing the illumination direction angle of the strobe device being adjusted, based on the second signal. With this method, the illumination direction angle of the strobe device can be remotely adjusted.
