Abstract: PROBLEM TO BE SOLVED: To realize reduction in total weight, by forming a winding portion by plastic deformation into a coil of the U-shaped bending area of the hanger rod, and then fixing such winding portion to an insulator via a cotter-pin provided through the winding portion from the lateral direction. SOLUTION: A U-shaped bending portion of a hanger rod 10 in the opposite side of the leg side portion 10c is plastically deformed in the form of coil to form the winding portion 10f and a pillar space in the condition provided through the cotter-pin 11 for contact is formed within a winding portion 10f. End part of the winding portion 10f is projected in the opposite direction to a tight sleeve 4 as a U-shaped puller 10g to use it for hooking during the wire pulling work. Moreover, the cotter-pin 11 has a head portion larger than the internal diameter of the winding portion 10f at its one end and a stopper pin is embedded to the through-hole at the other end.  As explained, the hanger rod 10 forms the winding portion 10f by coiling the U-shaped end portion formed in the shape of U as a whole and therefore it can be manufactured not only in the rather low cost but also in light weight as the total weight.

Abstract: PROBLEM TO BE SOLVED: To reduce the weight floor impact sound of a low frequency by forming the passage of a specific width between sound absorbing materials, and making a set area rate for the floor substrate area of the sound absorbing material a specific value. SOLUTION: A floor panel material 3 is juxtaposed through a plurality of support legs 2 on a floor slab 1, and a floor finish material 5 is laid on through a floor substrate material 4 on the upper face of the floor panel material 3. A sound absorbing material 6 is laid on the floor slab 1.

In addition, a set area rate for the floor substrate area of the sound absorbing material 6 is made 80% or higher. The thickness of the sound absorbing material is adjusted by properly laminating a plurality of the sound absorbing materials in accordance with the height of an underfloor space.  Even when a floor face receives large impact by weight, it is scattered on the whole floor face and impact sound transmitted to a lower floor is reduced by passing through the passage 10 while air of the underfloor space compressed by the deflection of the face material in the neighborhood of an impact point is sound-absorbed by the sound absorbing material 6.

Filed: 1991-12-30
Abstract: PURPOSE:To cope with high density wiring by reducing the fail rate of a second bond in the wire-bonding of a picture device and at the same time making it feasible to miniaturize a bonding pad. CONSTITUTION:The wire thickness delta of a second-bond part in the peripheral part of the mark of a bonding tool is set to be 1/15 to 1/4, preferably 1/6 to 1/4 of wire diameter. The wire thickness 6 of below 1/15 or above 1/4 of the wire diameter shows up a shortage of strength. The expansion of a wire in the second-bond part decreases as the wire thickness delta increases, so that the bonding pad may be miniaturized by setting the wire thickness delta to not less than 1/6 of the wire diameter.

IPC: B05D7/14
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To improve quality of coating and to reduce time and labor required for cleaning work for a drying oven by removing dust accumulated in the oven. SOLUTION: A base 7 running on a conveyer rail 6 laid under the floor out of an oven and a trestle 4 on which a work W is placed are formed separately up and down through a support 8 with a required height and the support 8 is passed through a slit 9 formed in the floor wall 3F of the drying oven 1 into the oven to move the work W in the oven and to dry it. In addition, when the floor face 3f is cleaned and a cleaning liq. is let to flow on the floor face 3f, the cleaning liq. flows down on the floor face 3f formed on an inclined face toward the slit 9 and while it washes dust accumulated on the floor face 3f away, it flows into dust recovery channels 16 and then, it is drained outside.  Therefore, before the dust made to fall on the floor face 3f grows to such a size that generates failure of coating, the dust can be simply removed only by letting the cleaning liq. flow and quality of the coating can be improved.
