Title: Dephosphorizing method
Inventor: TSUNEKAWA MASAO
IPC: C02F1/58
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To surely form a high strength magnesium ammonium phosphate(MAP) particle by specifying average retention time of MAP particle in a reaction column in a dephosphorizing method for depositing phosphorus by introducing a phosphorus-containing water into the inside of the reaction column and allowing to contact with MAP particle. SOLUTION: A part of treated water is taken out from the upper part of the reaction column 1 to a circulating pipe line 7 and circulated to the lower part of the reaction column 1 by connecting a raw water introducing pipe line 2, a feed pipe 4 for a magnesium salt solution and a feed pipe 5 of an alkali agent to the lower part of the reaction column 1. In such a case, the alkali agent is injected from the feed pipe 5 so that the pH detected by a pH meter 12 is in a range where MAP is deposited. The treated water lowered in the concentration of phosphorus by the deposition of MAP is discharged from a take-out pipe line 3 and on the other hand, the MAP particle grown in grain is taken out from a discharge pipe 6 in the lower part of the reaction column 1.  In the dephosphorizing method in this manner, the high strength MAP particle is formed by controlling the average retention time of MAP particle in the reaction column 1 to >=240 hr.

Title: Hot water washing device
Inventor: ARAKAWA MASAFUMI
IPC: E03D9/08
Filed: 1994-03-04
Abstract: PURPOSE:To prevent hot water from being jetted unexpectedly or at excessive blowout pressure, regarding a hot water washing device equipped with two pumps. CONSTITUTION:A confluent section 3 is formed at the intermediate position of a flow passage 10 connecting two pumps 1 and 2 to a washing nozzle 5. After starting a washing process, only one pump 1 is operated until the nozzle 5 finishes operation, and the other pump 2 is operated after the nozzle 5 is projected. According to this construction, water pressure acting on the nozzle 5 does not become excessive, as only the pump 1 is operated at the start of the washing process, thereby eliminating a possibility of jetting hot water unexpectedly or at excessive blowout pressure. After the projection of the nozzle 5, two pumps 1 and 2 are operated and, therefore, the required blowout pressure and washing water volume are maintained, thereby ensuring a proper hot water washing process.

Title: Semiconductor integrated circuit
Inventor: WATANABE KAZUKI
IPC: H01L21/822
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To avoid malfunction even if there is a crack in a chip by inspecting each circuit for any crack and stopping the circuit operation if any. SOLUTION: Regarding one or more resistors provided for each two sides of the outer edge of a portion to be subjected to chip crack detection as a constituent, a chip crack detecting portion having certain frequency characteristics and a potential change detecting portion are connected. The chip crack detecting portion F1 is a circuit having certain frequency characteristics, and the frequency characteristics are changed by variations in resistance due to a crack in a chip. Because the chip crack detecting portion changes the frequency components of an input signal S1 when a chip is cracked, a signal which is different from the input signal S1 enters the detecting circuit, causing an output signal S2 to differ from a signal which is outputted when the chip has no cracks.  Based on this theory, internal signals such as a clock signal are stopped when a chip is cracked, causing all circuit operations to stop.
