A multi-purpose spade includes a spade head having a 'V'-shaped cutout; a detachable tip constructed to substantially conform to the 'V'-shaped cutout of the spade head; and nuts and bolts for fastening the detachable tip to the spade head in which spade head includes first and second inner edges, and cutting edges or blades are formed on the first and second inner edges. However, such cutting edges or blades are not formed on a region adjacent to the pointed end of the &#x201c;V&#x201d;-shaped cutout, and first and second inner edges form an angle of about 30&#x2dc;40 degrees, and more preferably about 30 degrees. The first and second edge portions have longitudinal slots respectively to receive the first and second inner edges.

Multi-purpose spade having detachable tip

A multi-purpose spade includes a central plate, first and second edge plates, and a retreating crescent blade. The central plate is generally concave. The retreating crescent blade is formed along the tip portions of the central plate and the first and second plates. The inner edge portions of the first and second plates are connected to corresponding side portions of the central plate with a predetermined angle so as to form two crest portions on the front surfaces along the side portions of the central plate. The multi-purpose spade may further comprise an extending blade configured to be connected to the retreating crescent blade.

Multilayer ceramic chip capacitors which satisfy X7R requirements and which are compatible with reducing-atmosphere sintering conditions so that non-noble metals such as nickel, copper, and alloys thereof may be used for internal and external electrodes are made in accordance with the invention. The capacitors exhibit desirable dielectric properties (high capacitance, low dissipation factor, high insulation resistance), excellent performance on highly accelerated life testing, and very good resistance to dielectric breakdown. The dielectric layers preferably contain BaTiO as the major component and Mn O Y O , Ho O , CaCO , SiO , B O , Al O , MgO, and CaO as minor constituents. They are batched in a proportion that there are preferably present 99.00 to 98.5 wt. % BaTiO , 0.336 to 0.505 wt. % Mn O , 0.198 to 0.296 wt. % Y O , 0.132 to 0.198 wt. % Ho O , 0.199 to 0.299 wt. % CaCO , 0.057 to 0.085 wt. % SiO , 0.039 to 0.058 wt. % B O , 0.018 to 0.027 wt. % Al O , 0.016 to 0.025 wt. % MgO and 0.005 to 0.007 wt. % CaO. The B O , SiO , MgO, Al O , and CaO are preferably present in the form of pre-reacted glass. The preferred form of the invention may be sintered in the temperature range 1,200 to 1,300&deg; C. in a reducing atmosphere. Additionally, a re-oxidation procedure may be utilized during the sintering cycle to optimize the resistance of the ceramic to dielectric breakdown.

A multi-utility shoe brush system (11) is provided which includes a main body (13) having a several sides meeting other adjacent sides to form angles greater than ninety degrees so a plurality of paste applicator brushes (17, 19, 21b), a soft buffing brush (45), hard soil-removing brush (21a, 53), and one or more polishing pads (23, 27). A handle (31) is attached to the main body (13) to increase the efficiency of the use of the multi-utility shoe brush system (11), and its cleanliness. Each of the brushes and polishing pads is recommended to be removably attached to the main body (13). A shoe horn (49) is attached at the free end of the handle (31) for an additional utility.
