Title: White board eraser
Inventor: KAMISE YOSHIOMI
IPC: B43L21/00
Filed: 1994-12-27
Abstract: PURPOSE: To provide a white board eraser with an excellent erasing performance and reduced likelihood of leaving ink dross solidified on the surface to be erased. CONSTITUTION: Spherical parts are formed on each tip end of synthetic fiber with a thickness of 20 to 80 denier, and the synthetic fiber is made into a fiber bundle 2a, wherein the fiber bundles are bristled on the basement 1 so that the outer diameter (d) in the bristled surface (1a) of one synthetic fiber (2a) comes to be 2mm or shorter, and the projection length (h) from the bristle surface (1a) comes to be 4 to 8mm, and further the distance 1 between the centers of individual fiber bundles (2a) is at most two times the outer diameter in the bristle surface of one fiber bundle (2a), and also the lines passing through the centers of individual fiber bundles are arranged not to be in the same straight line in the bristle surface of the basement.  As a consequence of this constitution, an appropriate flexibility of the fiber bundle serves to erase handwriting, then a proper dislocation among respective fibers prevents ink dross from being solidified in a mass on the surface of the eraser, thereby obtaining a good erasing performance having no unerased parts of handwriting.

IPC: H05K3/40
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To form a tungsten plug without forming undesired tungsten volcanoes.  
     SOLUTION: The process for forming a tungsten plug comprises passivating a substrate having a contact hole with SiH 4 , forming a nucleation layer on the passivated substrate by reducing WF 6  with SiH 4  at relatively low pressures and depositing tungsten to substantially fill the contact hole by reducing WF 6  with H 2  at a relatively high pressure. Alternatively, rapid thermal annealing is used to cure pinhole defects in a titanium nitride layer on the substrate.
