Title: Agrochemical granule
Inventor: HASEGAWA TAIZO
IPC: A01N43/66
Filed: 1994-12-19
Abstract: PURPOSE: To obtain an agrochemical granule capable of efficiently manifesting the respective agrochemical activities by raising the floating ratio of a foliar absorption oriented agrochemlcal active ingredient to the water surface and reducing the floating ratio of a root part absorption oriented agrochemical active ingredient to the water surface and, i.e., arousing a difference between both in floating ratio. CONSTITUTION: This agrochemical granule is obtained by uniformly mixing a water-insoluble solid carrier (d) having >=1 specific gravity with a root part absorption oriented agrochemical ingredient (c), then granulating the resultant mixture and further impregnating the prepared granular substrate with a solution prepared by converting a foliar absorption oriented agrochemical active ingredient (a) into a dissolved state in a water-insoluble high-boiling organic solvent (b) having <1 specific gravity. The resultant agrochemical granule has a high floating ratio of the foliar absorption oriented agrochemical active ingredient to the water surface and a reduced floating ratio of the root part absorption oriented agrochemical active ingredient to the water surface.  As a result, a difference between the ingredients (a) and (c) in floating ratio to the water surface of a paddy field is aroused. A foliar absorption oriented herbicidally active ingredient is preferred as the foliar absorption oriented agrochemical active ingredient. An anilide-based, a triazine-based or a sulfonylurea-based herbicide is preferred as the root part absorption oriented agrochemical active ingredient.

Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a lighting system which is able to detect the occurrence of a failure, prevent the further deterioration of the failed part, and can prevent the waste of energy caused by the failure. SOLUTION: A lighting system is provided with a reflecting means 4 which reflects the sunlight, a rotationally driving means 14 which rotationally drives the reflection means 4, an azimuth detection means 15 which detects the azimuth angle of the reflection means 4 to which the reflection means 4 points, and a control means which calculates an azimuth angle of the sun, based on a reference time of a clock means, and controls the rotationally driving means based on the azimuth angles of the reflection means and the sun.  The control means discriminates whether the drive of the reflection means 4 by the rotationally driving means 14 is abnormal or not, based on a first azimuth difference calculated by subtracting the azimuth angle of the sun from that of the reflection means 4 before the driving and a second azimuth difference calculated by subtracting the azimuth angle of the sun from that of the reflection means 4 after the driving. When it is discriminated that it is abnormal, the drive for next time of the reflection means 4 by the rotationally driving means 14 is made to be stopped.

IPC: H01H33/66
Filed: 1988-12-14
Abstract: PURPOSE:To make it possible to perform soldering of an electrode containing a large amount of Bi so as to obtain the stable, low interrupting property of the vacuum interrupter, by joining the electrode formed from specific components to lead bar using solder the main components of which are Ti and Al. CONSTITUTION:An electrode 17, 18 comprises the components of 20 to 70 parts by weight Cu, 5 to 75 parts by weight Cr carbonate, 0.1 to 10 parts by weight Ni, and 1 to 20 parts by weight Bi, and is joined to a lead bar 15, 16 the main component of which is Cu, by means of solder the main components of which are Ti and Al; when Cu and Bi are infiltrated into an infiltration base material (skeleton) consisting of Cr carbonate and Ni, the Bi is deposited in a disposed state around Cr and Ni particles and scarcely exists between the crystal grains of Cu. Since therefore the Bi that the electrode contains can effectively be prevented from invading the junction interface to enable the electrode and the lead bar to be stably joined together by the solder, the low interrupting property of the interrupter can be maintained in a stable condition over a long period of time.
