Title: Method for purification of mercury contaminated soil
Inventor: MATSUYAMA AKITO
IPC: B09C1/08
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To remove mercury efficiently at a low cost while human safety is improved by a method whereon mercury is removed by heating mercury contaminated soil, an additive having bivalent iron as a main constituent is mixed in the soil by stirring, which is heated. SOLUTION: After mixing by stirring an additive having bivalent iron as a main constituent in mercury contaminated soil, that is treated by heating at a temperature of a mercury boiling point or lower. Thereby, a mercury component in the mercury contaminated soil is removed. That is, by storing and heating mercury and a mercury compound in the mercury contaminated soil with the additive of iron sulfide or the like, the mercury is removed by evaporation. The heating accelerates evaporation of metallic mercury from in the mercury contaminated soil. Further, by utilizing thermal denaturation owing to heating of the additive, even a stable mercury combined form such as mercury sulfide is decomposed into sulfur and mercury components to evaporate the mercury.  The additive has the divalent iron as main constituent and, for example, iron sulfides such as ferrous sulfide, iron disulfide, etc., are used.

IPC: H04N3/16
Filed: 1992-12-11
Abstract: PURPOSE: To extinguish fold-over by generating a phase-locked loop synchronizing with an nfH (n; an integer, fH; a frequency) timing signal, a phase-locked loop operating with the fH and synchronizing with the horizontal synchronizing components of a video signal, and a blanking signal for suppressing an electronic beam in a horizontal retrace interval corresponding to the nfH timing signal. CONSTITUTION: A one-chip processor 12 executes an intermediate frequency, video, luminance, and chrominance processing and a deflecting function. A phase-locked loop 14 divides a 32fH clock signal from a voltage control oscillator 13 by 32, and outputs 1fH. This is synchronizing with the horizontal synchronizing components of a video signal incoming from the loop 14. A dividing circuit 16 forms a 1fH to 2fH frequency converter, divides the 32fH oscillator output by a nominal count value 16, and generates a 2fH output. Thus, a video signal without any fold-over can be obtained.

Title: Method for drying gas and device therefor
Inventor: LANG CHRISTIAN KARL HENRIK
IPC: B01D53/26
Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To suppress the time required to regenerate a drying agent and the energy consumption to the minimum, in a method for drying gas and a device therefor. SOLUTION: One portion of dried gas is used for regeneration of a drying agent. This gas portion is heated in at least two continuous steps, and these steps are practiced at the different zones successively arranged in the flow direction of the gas portion passing through the drying agent. Also, since the heating in this zone is immediately stopped at the time when the drying agent in one zone was regenerated, while the succeeding zone is still regenerated with heating gas, the method is applied so that the zone is completely cooled with the gas portion for regeneration.

Title: Carrier
Inventor: OGAWA ATSUJI
IPC: B62B1/20
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To contract the handle of a carrier by rotating the engaging parts at both ends of a handle thereby releasing the fixation of the first and second pipes and also, releasing the fixation of the second and third pipes. SOLUTION: In the release method for the front stage, a coupling lever 50 goes up, against a spring, together with the rotation of a handle, so the first engaging piece 70 is released, being retreated by a first taper part 6. Moreover, at the same time when the first engaging piece 70 retreats, the handle is pressed down, and the first pipe 20 can enter the second pipe 30. In the release method for the rear stage, the engaging part of the handle is rotated to push up the coupling lever 50 to release the first pipe 20 on the front stage 20, thus the first pipe 20 can enter the second pipe 30. At this time, a steel ball 80 shifts automatically to the side of a small-diameter part, and it breaks away from the small hole 41 of the third pipe 40, and gets released, and pushing the second pipe 30 into the third pipe 40 will enable it to enter.  As a result, the release action can be combined with only the operation of the handle 10 of pulling the carrier.
