Experimental vibration analysis of the shadow mask
Optics and Lasers in Engineering, 1998 In this paper, the natural frequencies and mode shapes of the shadow mask in a multimedia monitor were measured by the modal testing technique and the amplitude fluctuation (AF) electronic speckle pattern interferometry (ESPI) method. Based on the obtained experimental results, it is advisable to investigate and optimize the assembly conditions of the ...

AN APPROACH OF SHADOW MASK FOR DEEP-HOLES PATTERNING
International Journal of Computational Engineering Science, 2003This paper presents a method to pattern metal in deep holes. We do this by etching holes through a separate wafer to form a shadow mask and then depositing metal by electron-beam evaporation or sputtering through the holes on this shadow mask on to the device wafer.

Effects of shadow‐mask voltage on the discharge in shadow‐mask PDPs
Journal of the Society for Information Display, 2009Abstract— A new type of ACPDP with a shadow mask (shadow‐mask PDP, SMPDP) has been developed, featuring an effective structure and lower cost. The distinct difference between an SMPDP and a conventional ACPDP is that the dielectric barrier ribs are replaced by a single metal shadow mask.

The Shadow Meets the Mask: Pyramid‐Based Shadow Removal
Computer Graphics Forum, 2008AbstractIn this paper we propose a novel method for detecting and removing shadows from a single image thereby obtaining a high‐quality shadow‐free image. With minimal user assistance, we first identify shadowed and lit areas on the same surface in the scene using an illumination‐invariant distance measure.

Journal of Management Inquiry, 1993
Using a psychodynamic perspective on intergroup relations, it is suggested that in-groups create enemy out-groups to avoid dealing with internally generated, emotionally laden issues—the group shadow—that exist within the in-group. In-groups develop an exaggerated view of themselves—the social mask—to sustain an illusion of harmony, homogeneity, and ...

Thin Solid Films, 2002
Abstract We investigate molecular beam epitaxy (MBE) regrowth through shadow masks developed from AlGaAs/GaAs layers on GaAs [001] substrates. Adjusting the directions of the molecular beams relative to the masks results in in situ lateral structuring.

MASKING AND SHADOW HEARING IN BONE CONDUCTION
Archives of Otolaryngology - Head and Neck Surgery, 1950IN THE performance of a hearing test the object of masking is to keep one ear occupied while the other ear is being tested. A complex noise consisting of the essential frequencies gives a satisfactory masking effect. The specific areas on the basilar membrane will resonate to the complex masking sound and will become refractory to stimulation from ...

Deep plasma etching of glass with a silicon shadow mask
Sensors and Actuators A: Physical, 2008 Inductively coupled plasma reactive ion etching (ICP RIE) has been successfully used for deep (>300 μm) etching of silica and glass with a non-bonded silicon shadow mask.

Automated shadow mask inspection using DSP
Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91, 2002Presents a new shadow mask inspection method which can detect the very small hole defects reliably and rapidly; the shadow mask line image data is periodical. The inspection method mainly depends on the fact that a small defect can be significantly emphasized in terms of the comparison between the image pixels departed by the period.
