Title: Method for keeping-freshness and growing of plant
Inventor: NISHIZAWA SHUICHI
IPC: A01N61/00
Filed: 1987-01-14
Abstract: PURPOSE:To prolong the life of live flower, etc., to promote the growth of vegetables and flowers and to keep the freshness of an plant and to effect the growth of a plant, without directly using a radioactive mineral in solid state, but by treating water with a natural radioactive mineral and allowing the treated water to be absorbed in a plant by spraying. CONSTITUTION:A natural radioactive mineral containing large amount of niobium oxide and yttrium oxide and small amount of radium oxide and thorium oxide (e.g. fergusonite) is preferably crushed to the size of pebble to increase the contacting area of the mineral with water and made to contact with water preferably at about normal temperature. The treated water is sprayed to and absorbed in a plant to keep the freshness and effect the growth of the plant. The treated water can be produced by charging >=100g of the mineral to 1m<3> of water, letting stand for >=6hr and preferably stirring the water. Since the treated water is used in the above process, it is not necessary to apply a natural radioactive mineral to plowed land in powdery form. Furthermore, hydroculture of a plant can be carried out only by circulating water treated in a treatment tank. Accordingly, the handleability of the treating agent can be improved.

IPC: B60W10/02
Filed: 1988-01-16
Abstract: PURPOSE:To smoothen the speed changing operation by mounting a revolution speed reducing means which reduces the revolution speed of an accelerating mechanism to the low speed range in connection with the disengaging operation of a clutch before the disengagement thereof is attained. CONSTITUTION:An operation arm 25 of an accelerating mechanism 18 is externally engaged with an operation shaft 18a in the idling state and has a helical spring 32 so that said arm 25 may be operated in contact with the pin 31 of an arm 30 fixed to the operation shaft 18a. A wire 33 is laid between said arm 30 and the swinging arm 17a of a main clutch pedal 17. When the clutch 3a is to be disengaged to shift the gear, before the complete disengagement state of the clutch 3a, a revolution speed reducing means (wire) 33 operates the accelerating mechanism 18 to the low speed range. As a result, the revolution of the gear system of a transmission case placed at the lower transmission position than the clutch 3a may be reduced. Thus, the inertia action of the gear system may be reduced so that the speed changing operation may be smoothened.

Abstract: PURPOSE:To make the surface area of catalyst active site greater by enlarging the cracks in steel material by the procedure in which an Al-layer-coated steel material is subjected to a heat diffusion alloying treatment, and then the Al content is eluted from the steel material surface followed by activation by oxidation. CONSTITUTION:A SUS-304 steel material is dipped in a molten Al bath to coat it with Al-layer, and then subjected to an Al-steel inter-solid phase diffusion alloying treatment in an electric oven. Then, the steel thus treated is cooled with water, and then dispped in a corrosion liquid (e.g., an approx. 25% nitric acid solution, etc.,) to accelarate the corrosion of the Al-steel solid solution region and the steel body. Then, the steel is dipped in an alkaline aqueous solution to create porous steel surface due to the elution of Al, and then the porous layer is activated by oxidation. The denitrification catalyst thus obtained exhibits high catalytic activity even when used in small quantities, and thus the miniaturization of denitrification apparatus can be attained. 1 in the Fig. is steel material, 3 is solid solution region, 2 is alloying layer, and 4 is crack.

Filed: 1983-01-20
Abstract: PURPOSE:To maintain the liquid level in a solar heat collector in a predetermined range, constantly collect heat mainly through exchange of latent heat and contrive to enhance heat-collecting performance, by providing a liquid-reserving tank in which a ball tap is provided. CONSTITUTION:When collection of heat by evaporation of a latent heat type heat-transmitting medium in the solar heat collector 1 progresses, the liquid level is lowered, and the liquid level in the liquid-reserving tank 12 is also lowered correspondingly, resulting in that the ball tap 11 is opened. At this time, the pressure in a pipe provided between a pump 4 and the ball tap 11 is lowered below that in the condition wherein the tap 11 is closed. Then lowering of the pressure is detected by a pressure switch 10, and an electric current is passed to the pump 4 to start operation through a controller 13. When the liquid level is raised to a certain level, and the ball tap 12 is closed, the pressure in the pipe is raised by the pump 4. By these operations, the medium in a liquid state is fed in accordance with the quantity of the medium evaporated in the collector 1. Accordingly, heat is constantly collected mainly through exchange of latent heat, irrespectively of variations in the intensity of solar radiation, namely, variations in the quantity of the medium evaporated.
