Title: Production of decorative article
Inventor: HORIKIRI YATARO
IPC: G09B19/10
Filed: 1993-09-29
Abstract: PURPOSE:To obtain a method for making a decorative article provided with a three-dimensional decoration by mounting paper, wood, or metal or other thin pieces on a base body of a plate or box form in an erected state. CONSTITUTION:A cut line 2 is formed in a required pattern on a base body 1 made of a foamed resin. Following the cut line 2, the cut line 2 is widened. A flexible thin piece 5 is cut to a required length and inserted in the cut line 2 to a predetermined depth. In this manner, the thin pieces 5 are erected on the base body 1 to form the required three-dimensional pattern as a whole. In this manner, even untrained hands can make a decorative article provided with a three-dimensional decoration in a simple manner in homes. After the thin piece 5 is inserted in the cut line 2 on the base body 1, the foamed resin plastically deforms to shrink the cut line 2, thereby preventing the thin piece 5 from easily slipping off the cut line 2. In addition, practicability can be also provided to the decorative article, as required.

Title: Lead frame semiconductor device
Inventor: SHINOHARA TOSHIAKI
IPC: H01L23/495
Filed: 1986-10-13
Abstract: PURPOSE:To prevent the occurrence of a burr by a method wherein a lead-plated layer with a thickness of 1-20 mu is formed on an external lead at the outside of sealing resin and on a tie bar so that the layer cannot melt at a wiring operation and a plasticsealing operation and so that the layer to be deformed during a fastening operation by a mold can close a gap. CONSTITUTION:A lead-plated layer 13 with a thichness of 1-20 mu is formed on the surface and the reverse side of a lead frame in such a way that the layer covers the region from the outside of resin to the part which exceeds a tie bar 2 a little. Because the melting point of plated lead is 327  deg.C and is higher than the bonding temperature of a chip and a thin wire, the plated lead does not melt during the assembly. In addition because the gap at a lead frame 11, an upper mold 9 and a lower mold 10 is closed after the lead-plated layer 13 bas been deformed, it is possible to prevent the resin from flowing out. Even if the resin flows out, it is deposited on the lead-plated layer. If a 15% solution of nitric acid is used during a solder-plating process, the resin burr can be removed together with the lead-plated layer. Through this constitution, it is not necessary to include a process and an installation for a deburring operation such as a conventional honing operation or the like.

Abstract: PURPOSE:To raise the upper limit of an oscillated frequency to prevent oscillation from stopping at a power-on time or the like by constituting a monostable multivibrator with two OR and NOR gates and obtaining outputs from reset- side gates NOR or NOR and OR. CONSTITUTION:When a capacitor 52 is charged up to the potential of a constant voltage power source 58 by a variable current source 51, the output of a comparator is inputted to the monostable multivibrator consisting of OR and NOR gates 60 and 61 and a delay circuit 54. The capacitor is discharged by this output to continue oscillation. If the capacitor 52 is overcharged at a power- on time or by an excessive noise current, the potential of the capacitor cannot be discharged up to a reference potential or lower during an output pulse width of an output 55, and the output of the comparator 53 is held in the ''1'' state. Even in this case, the monostable multivibrator is operated as a bistable multivibrator consisting of an inverter 81 and a delay circuit 82 (corresponding to the delay circuit 54) and is self-oscillated and is restored to normal oscillation.

Title: Method for recovering copper from copper converter slag
Inventor: FUJII TAKAYOSHI
IPC: C22B7/04
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To lower the viscosity of molten slag and to recover copper at a high yield by mixing the oxygen less than the oxygen necessary for the complete combustion of a reducing agent with this reducing agent and blowing the reducing agent into the slag at the time of blowing the reducing agent into the slag in a copper smelting converter stage. SOLUTION: The reducing agent (for example, propane) consisting of a petroleum liquefied gas is blown into the slag in the molten state formed in the slag making period of the copper converter operation to reduce magnetite and to recover a copper-component. At this time, the oxygen of the quantity adjusted to <=0.1 in oxygen ratio assuming the quantity of the oxygen to effect the complete combustion of the reducing agent as 1, is mixed with the propane and is blown to the slag in the molten state kept at least at <=1200 deg.C in at least part of the period for blowing the reducing agent to the slag. As a result, the viscosity of the slag is lowered and the petroleum liquefied gas is made usable as the reducing agent with the good reduction efficiency. The copper is thus recovered at a high yield from the slag.
