Title: Removal of phosphorus
Inventor: FUKASE TETSURO
IPC: C02F1/58
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To enable the production and recovery of high strength MAP particles by a method in which, when phosphorus is removed by introducing drainage containing phosphorus into a reaction column and keeping pH within a prescribed range in the presence of a magnesium salt and an ammonium salt, and the pH in the reaction column is kept within a prescribed range even when drainage does not flow into the column. SOLUTION: The introduction piping 2 and supply pipes 4, 5 of raw water are connected to the lower part of a reaction column 1. In the reaction column 1, an alkali agent is injected from the supply pipe 5 so that the pH detected by a pH meter 12 is in range to deposit MAP. When magnesium is in shortage for the deposition of MAP, a magnesium salt solution is infected from the supply pipe 4. MAP is granulated using MAP particles as seed crystals in the reaction column 1, and the grown MAP particles are taken out from a discharge pipe 6. In this process, even when drainage is not introduced or the phosphorus concentration of drainage is too low for crystallization, the pH in the reaction column 1 is kept within a prescribed range to enable the production of the high strength MAP particles.

Title: Antiskid control device
Inventor: TAKEMOTO SHINYA
IPC: B60T8/1769
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To effectively control a center differential gear even when it is set to the constrained state. SOLUTION: When a center differential gear is set to the constrained state (step 160), a vehicle is not traveled on a μ-split road (step 170), and a phenomenon peculiar to a four-wheel drip is detected (step 180), then a judgment flag is set on (step 190). When the judgment flag is set on and the control mode for the low-speed side wheel of front wheels is set to the decompression mode, the control mode for rear wheels is forcibly set to the decompression mode (steps 260-280), and otherwise normal antiskid control is applied (steps 240, 250). The brake oil pressure of the rear wheels is limited only when control is really required, so that the brake oil pressure of the rear wheels is prevented from unnecessarily reducing and resulting in extending the braking distance except in four-wheel drop state.

Inventor: KURAMOTO SHINICHI
IPC: B41M5/00
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To enable the ejection of a high viscosity ink with little bleeding on paper. SOLUTION: A roll 22 for supplying thickening material particles 110 is fitted in an ink channel 16 in the vicinity of an orifice 11 of a nozzle 10. The thickening material particles 110 stored in a particle supply tank 21 are adhered on the roll 22 surface so as to be conveyed in the ink channel 16 according to rotation of the roll 22. When an ink 100 is ejected by the drive of a piezoelectric element 12, or the like, the ink scavenges the thickening material particles 110 on the roll 22 surface exposed in the ink channel 16. Since the thickening material particles 110 are dissolved in the ink, the ink droplets ejected from the orifice 11 can be highly viscous.

IPC: A23L19/00
Filed: 1983-04-09
Abstract: PURPOSE:To enable the permanent coloring of the stalk of the white ginger, and to prevent the coloring of the other root part of the ginger, by immersing the stalk part of a sprouting ginger in a solution of Food Red No.3, and then immersing in an acid solution. CONSTITUTION:The stalk part of a sprouting ginger is immersed in a solution of Food Red No.3, and the colored stalk part is immersed in a solution of an acid to fix and insolubilize the pigment. The temperature of the liquid for the immersion of the ginger may be normal temperature, however, the liquid is preferably heated at 50-95 deg.C while preventing the boiling of the solution to shorten the coloring time. The coloring part of the sprouting ginger should be restricted to the stalk. The coloring or the ginger root is also possible, but it spoils the commercial value of ginger. It is preferable to apply a number of proper incisions to the skin of the ginger before immersion to improve the coloring effect.
