Abstract: PURPOSE:To reduce the level differences near the boundaries of paint films and to control paint widths as desired by installing a shielding material having the construction that permits passage of a part of spraying paint between a spray gun and a material to be painted. CONSTITUTION:If it is desired to paint the part A-C of a material to be painted (d), a shielding material (e) that permits the passage of a part of spray paint is installed between a spray gun (c) and the material (d) to allow passage of the paint only through the preceding end part of the shielding material (e). Then a thick paint film is obtained in the part A-B, and a gently sloping paint film is obtained in the part B-C, so that no level differences are produced at the boundaries of the paint films between the painting part and non-painting part. The preceding end part of the material (e) is formed like a comb, a net or bamboo whisk form to allow passage of a part of the paint. The material (e) is formed usually into a shape of a plate, circular cone, pyramid or disc. Thus, the need for using nozzles of the sizes conforming to the painting widths each time according to the painting widths is eliminated and the work is made simple.

CONSTITUTION:Dibutoxy Mg of 23.5wt% and a catalyst, dibutyl-tin dilaurate of 5wt% are respecgively added to the main component of a metal alcoxide, Si tetraoxide of 76.5wt% in such a way that SiO2 and MgO can be obtained in a wt. ratio of 80:20 by applying the relation between the common logarithm of the linear expansion coefficient of an oxide MOx, which can be obtained from the alcoxide of a metal element M and is a component of the metal alcoxide, and the wt% of each component constituting the metal alcoxide, and the metal alcoxide is stirred in isopropyl alcohole of 100wt%. The Si substrate is applied with the mixed solution, and after being preheated at 100 deg.C, the substrate is heated up to 600 deg.C at a rate of 10 deg.C every minute. When the wt% of the SiO2 is chosen in an extent of 85-73wt%, the linear expansion coefficient thereof is almost same as that of the Si substrate. As a result, an SiO2-MgO system compositional film having no crack and pinhole can be obtained. Similarly, by using a multicomponent-system metal alcoxide, the composition ratio of an oxide, which doesn't crack, can be obtained and a good-quality oxide layer can be formed on various substrates.

IPC: A47B88/00
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To mount a latch, which is identical in shape, on the rear surface of a drawer's end plate whose elevation is different, by determining the laid out elevation of the latch so that a downward set up working piece may be placed into contact with one of upper and lower contact bodies at the tip of a rotary shaft. SOLUTION: In the case when the height dimension H1 of a latch 20 from an axial line of a rotary shaft 8 of a drawer 7 up to a latch claw 24 is short, a layout elevation H2 of the latch 20 from the rotary shaft 8 is set. In this case, a vertical area 15a of an L-shaped release layout part is set so that it may not be interfered with the tip of an upper contact body 22. In the case when the height H3 from the axial line of the rotary shaft 8 of the drawer 7 up to the latch claw 24 of the latch body 20 is set slightly longer, the layout height between the rotary shaft 8 and the latch body 20 is set. At least two contact bodies are preliminarily provided on the latch body 20 in such a fashion that they may be projected vertically with a proper spacing, thereby laying out a working piece 12 on the rotary shaft 8 by way of a curved laid out area with a stag e.  This construction makes it possible to mount a latch device on a drawer whose height is different by simply changing the laid out elevation of the latch body 20.
