Title: Separation of palladium and cesium from acid solution of nitric acid such as high level radioactive waste liquid
Inventor: TANIHARA KOICHI
IPC: C22B11/00
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To efficiently separate Pd and Cs by first bringing coppery insoluble hexacyanoferrate (II), oxidation-treated substance thereof, or copper hexacyanoferrate (III) into contact with an acidic solution of nitric acid to absorptively separate Pd selectively. SOLUTION: A material consisting of oxidation-treated substance of coppery insoluble hexacyanoferrate (II) or copper hexacyanoferrate (III), by which Pd is adsorbed and supported under the condition that no nitrous acid is allowed to coexist, is subjected to reduction treatment. A solution, from which Pd is removed, is brought into contact with the above material, by which Cs is absorptively separated selectively. The absorbent, which is made to adsorb Cs, is subjected to oxidation treatment using a nitric acid solution containing nitrous acid, by which Cs is desorbed. The adsorbent, from which Cs is desorbed, is subjected to reduction treatment and reclaimed as a Cs adsorbent. It is preferable that contact time with the acidic solution of nitric acid for Pd separation is regulated to >=48 hr.  Moreover, it is desirable to add hydrazine, sulfamic acid, etc., as antioxidant in order to produce the maximum Pd adsorptivity of coppery insoluble hexacyanoferrate (II).

Title: Radio louding broadcast system
Inventor: MIYAMOTO YOSHIO
IPC: H04H20/76
Filed: 1980-04-28
Abstract: PURPOSE:To dissolve restrictions of place of the broadcaster completely, by using the radio coupling cable in stead of the feed cable of the loudspeaker. CONSTITUTION:Radio waves radiated from the broadcaster having mobile radio equipment 14 are connected to radio coupling cable 9 spread in the object section and reach the feeding-side terminal. These radio waves are separated by signal filter 11 and are input to radio receiver 12, and the demodulated sound signal is amplified to a proper level and is fed to the sound-side terminal of signal filter 11 and is transmitted to radio coupling cable 9. The transmitted sound signal is fed to sound speakers 2-2'' in positions of branch filters 10-10'' inserted properly on cable 9, thereby performing a desired sound broadcast.

Title: Vibration breaker
Inventor: KAMIBAYASHI HIDEAKI
IPC: H02H5/00
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a vibration breaker for cutting off a power source due to vibration of an earthquake by connecting a breaker lever to a dead weight mounted on a pan by a thread. SOLUTION: When a dead weight 1 mounted on a pan 4 for the weight is fallen by vibration of an earthquake, a lever 3 of a power source breaker 5 attached to a distribution board 6 by a thread connected to the weight 1 is lowered and the power source is cut off. The power supply breaker 5 can be thus automatically cut off by the vibration of the earthquake so that, when a refugee returns home from a refuge, the power supply can be energized, after he or she confirms whether gas is leaked or not caused by breaking of a gas pipe and electric appliances such as electric refrigerator are broken or not. This constitution can prevent a fire occurring simultaneously by gas leakage caused by breaking of the gas pipe which catches fire from spark of a motor of an electric appliance.

Title: Holding member for wire and magnetic head device using its holding member
Inventor: HOSHI ISAMU
IPC: G11B5/60
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To discriminate whether it is discontinued by element destruction or the simple discontinuity by the cut lead wire in the case that the discontinuity of the lead wire is generated inside a tube. SOLUTION: In this holding member of a wire, a planar holding piece is formed at a part for holding the lead wire 11, a curved plate part 14 is provided in the base end side of the holding piece and a pressing piece 15 more easily bendable than the curved plate part 14 is formed on the tip side of the holding piece. Then, the pressing piece 15 is formed narrower than the curved plate part 14. Thus, at the time of fixing the lead wire 11, since the curved plate part 14 kept as it is and only the pressing piece 15 is bent, the lead wire 11 is fixed in a fixed holding state at all times and the lead wire 11 is not discontinued or insufficiently fixed. Thus, whether it is the discontinuity by the element destruction or the simple discontinuity by the cut lead wire 11 is easily discriminated.
