Title: Method for preventing damage by thrips
Inventor: SHIMOOKA HIDETAKA
IPC: A01N59/00
Filed: 1984-01-17
Abstract: PURPOSE:To prevent the damage of citrus fruits caused by thrips, by compounding a white fine powder of mineral having a specific particle diameter with a spreader, and applying the mixture at a specific concentration. CONSTITUTION:White fine powder of mineral (e.g. calcium carbonate, clay, kaolin, talc, titanium oxide, zinc oxide, etc.) having average particle diameter of 0.1-2.5mu is mixed with a spreader such as vinyl acetate resin, PVA, CMC, starch, etc., dispersed in water at a solid concentration of <=2kg per 40l of water, and sprayed to citrus fruit tree to prevent the damage by thrips (scirtothrips dorsalis). The white mineral fine powder can be retained on the surface of the leaf for about 20-30 days by the use of the spreader to maintain the repelling effect. However, excessive use of the agent lowers the reflectivity of the leaf to lower the repelling effect, and may cause the phytotoxicity such as the inhibition of photosynthesis, etc. Accordingly, it is preferable to add a proper amount of the agent by measuring the reflectivity of the leaf.

Filed: 1978-01-24
Abstract: PURPOSE:To make the characteristics as a light modulator close to those of waveguide having many single modes and propagating only several modes, by increasing the light intensity density while making use of the merits of the multimode waveguide. CONSTITUTION:As an optical guide, LiTaO3 single crystal 1 of multimode waveguide is used, and the section thereof has a continuously changing curvature radius, namely smaller in curvature radius in the vicinity of the entry and exit ends of multimode fibers 3 and 5, and larger in curvature radius in the central part mounting a stripe-formed electrode 2 of Cr-Al. Both ends of this single crystal are polished so as to directly coupled with the fibers. When the applied voltage to this modulator is decreased, it becomes close to a two-dimensional waveguide, so that the quantity of light transmitted to the fiber 5 may be reduced. This effect is found only in the TE mode, and the TM mode is cut by means of a thin film polarizing element 4.

Title: Controlling circuit of combusting device
Inventor: ASANO YOSHIO
IPC: F23N5/20
Filed: 1982-01-20
Abstract: PURPOSE:To secure energy saving and safeness by a method wherein when ignition is performed by an ignition timer, combustion is interrupted by an electronic timer after a certain period of time elapses. CONSTITUTION:In case of automatic ignition by an ignition timer, a changeover switch 20 is opened and the ignition timer is set at a desired time. Then contacts 2-3 and 5-6 become conductive to start power supply to an ignition timer motor 2. After a preset time period elapses, the contacts 2-3 and 5-4 become conductive so that the power supply to circuits of the ignition timer motor 2, sheath heater 5 and the like is started to begin preheating. At this time, if a combustion switch 7 is closed, after a completion of the preheating, the control is transferred to an ignition. Then, after elapse of a certain period of time, the ignition timer 3 moves automatically to OFF position, rendering contacts 2-1 and 5-4 conductive. Accordingly, the power supply to all the circuits is interrupted to stop the combustion. Thus the energy saving and safeness of the combustor can be secured.
