    Abstract: A vortex flowmeter for calculating the flow rate of a measuring fluid flowing through a flow path using ultrasonic signals subjected to changes in the propagation time due to Karman vortices, comprising a reference signal generating device for outputting a plurality of reference signals of different phases; a signal analyzing device for outputting an input status signal by determining the relationship between the phases of the ultrasonic signals and each reference signal; a plurality of phase detectors for outputting phase signals by detecting the phase difference between the ultrasonic signals and the reference signals; and a channel selector for selecting the optimum phase signal using the input status signal and for outputting the optimum phase signal as a selection signal, wherein the flow rate signals are computed and outputted using the selected phase signal. The vortices are thus stably detected even when a phase change due to the vortices in the vortex flowmeter is large.

    Abstract: In an iron powder for coating a seed, the mass percentage of an iron powder with a particle size of 63 μm or less is 0% to 75%, the mass percentage of an iron powder with a particle size of more than 63 gm to 150 μm is 25% to 100%, and the mass percentage of an iron powder with a particle size of more than 150 μm is 0% to 50%. This allows the iron powder to form a coating from which the iron powder is unlikely to drop during not only seeding but also transportation and also allows an iron powder-coated seed coated with the iron powder to be obtained. The following iron powder and rice seed can be obtained: an iron powder, unlikely to damage rice seeds and easy to handle, for coating a rice seed and an iron powder-coated rice seed coated with the iron powder.

    Abstract: An inkjet recording apparatus includes an ink particle generation unit that makes a pressurized ink injected from a nozzle into particles, a charging unit that electrically charges the ink particle of those subjected to particulation, which corresponds to a dot to be printed, a polarizing unit that polarizes the electrically charged ink particle in a polarizing electric field, a collection unit that allows a gutter to collect the ink particle corresponding to the dot that is not printed, and a character forming unit that forms a character as a dot matrix on a printing object. A phase detection charging signal is applied to the ink particle that is not used for printing when forming the dot matrix character so as to detect an optimum charging timing in a process of forming the dot matrix character.
