Title: Picture frame device
Inventor: YU-WEI HSU
IPC: A47G1/06
Filed: 2018-10-23
Abstract: A difficulty with picture frames comprising a transparent front plate and a rear plate is that the threaded fasteners usually positioned at corners of such picture frames used to hold the front and rear plate together do not hold a picture, placed between the front and rear plates, in place. The picture is either not firmly positioned making positioning inconvenient or alternative the picture can be adhered onto the rear plate making it difficult to replace the picture. The present invention provides a picture frame device includes a main frame unit and a first pressing unit. The main frame unit includes a frame body having a front plate, two connecting plates extending integrally and backward from two opposite sides of the front plate respectively, and two extending plates extending integrally and respectively from the connecting plates and toward each other. The front plate, the connecting plates and the extending plates cooperatively define an accommodating space. The frame body is made of a transparent plastic material. The first pressing unit includes a plurality of first fastening portions respectively disposed on the extending plates, and a plurality of first pressing portions respectively disposed on the first fastening portions in a way that each first pressing portion is moveably engaged with one of the first fastening portions and moveable toward or away from the front plate.

Abstract: FIELD: electronic and ionic spectroscopy of surface of solids and gases. SUBSTANCE: spectrometer uses an axisymmetric energy analyzer of the "electrostatic mirror" type with Z-axis of symmetry, plane position-sensitive detector located perpendicularly to the Z-axis, and a specimen, whose center of emission region is on the Z-axis. The field-setting electrodes look like two electrically insulated from each other coaxial circular tapered surfaces with a common vertex. The inlet and outlet annular diaphragms are cut out in the inner electrode so that their boundaries are located in planes perpendicular to the Z-axis. The inlet diaphragm is narrower than the outlet one and positioned closer to the common vertex of the cones. The center of the emission source is positioned on the axis, in the middle plane of the inlet diaphragm. The sensing surface of the position- sensitive detector is located farther from the cones vertex than any of the diaphragms, on the same side of the Z-axis as these diaphragms. The device makes it possible to simultaneously indicate the spectra of emission of particles flying from the source in any direction near a definite plane perpendicular to the Z-axis. It will provide, for example, for examining of the relationship betweenenergy of electron and its wave vector near the selected crystallographic plane simultaneously in all directions lying in this plane, and energy δE. in the final range. At instrument dimensions of about 700 mm, emission source diameter of 0.35 mm, resolution 0,08%≲ΔE/E≲0,13% in range 2%≲δE/E≲3,5%.. EFFECT: enhanced accuracy.
