摘要:
A disinfection system of a contact lens comprising immersing the contact lens in a disinfecting solution containing hydrogen peroxide in a concentration of 1 to 10% and neutralizing the hydrogen peroxide in the disinfecting solution through contact with a metal catalyst, where the disinfecting solution contains an organic carboxylic acid or a salt of the organic carboxylic acid, the organic carboxylic acid having a structure in which a hydroxyl group and a carboxyl group are bonded to one carbon atom; the disinfecting solution is adjusted to have a pH of 6 to 8; and the disinfecting solution after the neutralization is adjusted to have an osmotic pressure of 250 to 350 mOsm.

摘要:
A contact lens case including a container main body provided with a housing recess for storing a contact lens and a liquid agent, and a lid that is connected to the container main body via a hinge in a freely openable and closable manner. A lens holding body is displaceably housed in the housing recess, and by connecting the lid and the lens holding body via a connecting member, the lens holding body can undergo rising and falling displacement following open and close action of the lid around the hinge. A displacement restricting member is provided that restricts a direction of the rising and falling displacement of the lens holding body to the vertical direction that coincides with a depth direction of the housing recess.

Three-phase TSCs are delta-connected to three-phase AC buses. Each TSC includes a reactor, a capacitor, and a thyristor switch that are electrically connected in series. The thyristor switches of the three phases are arranged so that the terminal-to-terminal distance between respective thyristor switches of respective phases are not uniform. The three-phase TSCs are configured so that the TSCs of two of the three phases having a shortest terminal-to-terminal distance therebetween are opposite to each other in terms of connection order in which the thyristor switch and the capacitor are electrically connected along a loop path made up of the delta-connected TSCs.

A power converting apparatus is configured with single-phase sub-converters (4) connected to AC input lines of individual phases of a three-phase main converter (3) in series therewith. In a control device (12) for performing output control of the power converting apparatus, a current command value calculating circuit (20) which adjusts a DC voltage command given to the main converter (3) so that DC voltages of the sub-converters (4) follow a command and generates AC current commands so that a DC voltage of the main converter (3) follows the DC voltage command is configured with a CPU, and AC currents are controlled by switching output voltage levels of the sub-converters (4) at an AC side thereof so that deviations of instantaneous AC current values from the AC current commands become smaller.

摘要:
To provide a liquid preparation for contact lens wherein: the liquid preparation for contact lens assures an excellent disinfecting effect and a sufficiently high degree of safety to the eyes of the lens wearer; the liquid preparation for contact lens does not adversely affect the contact lens, such as a change of the size of the contact lens; and the liquid preparation for contact lens advantageously restrains a generation of deposits on the lens. The liquid preparation for contact lens is prepared, so as to comprise: at least one disinfectant selected from the group consisting of germicidal biguanides and germicidal quaternary ammonium salts (component A); glycolic acid and/or asparatic acid (component B); and 2-amino-2-methyl-1,3-propanediol or a salt thereof (component C), wherein the component B and the component C fulfill a predetermined molar ratio.
