Title: Manufacture of high-silicon pig iron
Inventor: MEGURO MASARU
IPC: C21C1/08
Filed: 1986-02-21
Abstract: PURPOSE:To obtain high-silicon pig iron with an existing apparatus for pretreating molten pig iron in a high yield of a siliconizing agent by decarburizing molten pig iron discharged from a blast furnace by the amount of carbon corresponding to a surplus by siliconization, raising the temp. of the molten pig iron with the resulting carbon as a heat source and siliconizing the molten pig iron. CONSTITUTION:Molten pig iron discharged from a blast furnace is decarburized by oxidation to the amount of carbon equilibrating silicon after siliconization to crystallize carbon, the temp. of the molten pig iron is raised with the crystallized carbon as a heat source and then the molten pig iron is siliconized. Since the amount of carbon is regulated, when molten Fe-Si or powdery Fe-Si is added and agitated, the yield is enhanced. Even when >=about 5% Si is added, Fe-Si is perfectly melted and high-silicon pig iron is obtd. at a low cost.

Title: Handset of cordless telephone
Inventor: TAKEMOTO HIROAKI
IPC: H04M1/06
Filed: 1991-02-06
Abstract: PURPOSE:To switch the handset of a cordless telephone without increasing the number of keys and without degrading the function of the handset by using a single key for executing the mute function and suspended function when muting talking. CONSTITUTION:When it is desired to mute talking, push holding key 3. Then, the mute can be done with the line left connected, and when pushing the key 3 again, the mute is released and talking can be reopened. Further, if it is desired to transfer talking to another handset, push key 3. Then, the handset interrupts talking with a base unit, and is set into a waiting mode. Furthermore, when pushing key 3 or the start key on the handset at the destination to which transfer of talking is desired, talking with the base unit is reopened, whereby since both the mute function and the suspended function can be carried out by a single key operation, switching of talking can be done without increasing the number of keys and without degrading the function.
