Title: Ink for ink jet recording
Inventor: TSUJIHIRO MASAKI
IPC: C09D11/00
Filed: 1990-02-28
Abstract: PURPOSE:To prepare the title ink having an excellent dispersion stability of a colorant in the ink and forming a recording image with high density, contrast, and resolution without blurring by incorporating emulsified or dispersed polymer particles dyed with a dye as the colorant into the ink. CONSTITUTION:In step A, an emulsion wherein spherical polymer particles 4A are dispersed in an aq. medium 3 is prepd. by emulsion or dispersion polymn. In step B, a suitable dye 6, e.g. a disperse dye, is added to the emulsion to dye the particles. Thus, as shown in step C, substantially the whole of the dye is exhausted to give dyed particles 4. The resulting emulsion, as such or after being subjected to treatments necessary to produce an ink, is used as an ink. The ink has an improved dispersion stability, is prevented from blurring of ink dots, and forms a recording image high in the density, contrast, and resolution and excellent in the water resistance and fixability.

Title: Method for charging lead-acid battery
Inventor: IMAI HIROYUKI
IPC: G01R19/165
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a proper charge to a lead-acid battery by allowing a charge current to have a specific relationship in a multistage constant-current charge finished in the nth process. SOLUTION: Shown in an expression is a charge current: in the expression, I1 is the charge current of a first process, n is an integral of 3 or more. Preferably, the charge in the last stage is an amount of charge electricity until the previous stage or three or more of multi-stage constant-current charge finished by the time calculated by charge time; where the number of charge stages is n, the charge current has a relationship shown in the expression. By setting the charge current low, the rise of the electric current density is low so that the reduction in the amount of charge electricity from the discharge condition to hydrogen generation due to repeated cycles can be suppressed. Accordingly, when the electric current is set low, accuracy of the amount of discharge electricity until the hydrogen generation assumed from the amount of the charge electricity becomes high.  Since low charge current prolongs charge time, setting the charge current so low is not preferable.
