An object of the present invention is to provide a separation medium and a separation method, ensuring high selectivity and good separation efficiency for specific steviol glycosides. The present invention is related to a separation medium in which polyethyleneimine is immobilized to porous particles of a (meth)acrylic polymer having a crosslinked structure and a hydroxyl group.

Separation medium, use for separation medium, steviol glycoside separation method using separation medium, and steviol glycoside production method using separation method

A space probing apparatus is provided that can further enhance its thermal protective function for electronic apparatuses and batteries that are apparatuses each having a narrow range of permissible temperature. The space probing apparatus includes, as a vehicle bodythat is an apparatus body, an inner housingthat accommodates an electronic apparatusand a batteryand an outer housingthat accommodates the inner housingsupporting the inner housingafloat therein. A thermal insulating layeris formed between the inner housingand the outer housingusing a space therebetween. A heat dissipating bodyis included in an upper portion of the inner housingA lidis included in an upper portion of the outer housingThe whole outer faces of the inner and the outer housingsandare each covered with a thermal insulating materialThereby, in the nighttime, the temperature of the batteryis maintained using the least necessary amount of heat generated and, thereby, the electronic apparatusand the batteryare protected from an ultralow temperature. In the daytime, the lidis opened and heat is discharged using the heat dissipating bodyand, thereby, the electronic apparatusand the batteryare protected from a high temperature.

In a postal information input apparatus in which when a postcode to be read by a reader of a postal matter sorting machine cannot be normally read, a correct postcode is reentered manually from an input device, a first display means which displays on a display device of the input apparatus a first display so as to indicate that the postal information input apparatus receives a data to be input from the postal matter sorting machine, and also displays an unprocessed number in the postal information input apparatus, is provided.

Postal information input apparatus and a data display method thereof

An object of the present invention is to provide a filter material capable of killing microorganisms, bacteria, fungi or viruses in air or liquids. Antimicrobial organic polymer materials of the present invention comprise an organic polymer material having a polymer side chain containing a unit derived from an N-alkyl-N-vinylalkylamide on a backbone of a polymer substrate, wherein triiodide ion is carried on said organic polymer material.

Bactericidal organic polymeric material

An apparatus for exposing an optical master disk includes an exposure section, an exposure control section, a guide groove exposure voltage supplier and a modulator. The exposure section is for exposing a guide groove and pre-pits by different laser beams, and the exposure control section is for controlling an exposure voltage of the laser beams in the exposure section and an exposure timing. The guide groove exposure voltage supplier is for supplying, in accordance with the pre-pit designation signal, to the exposure section a guide groove exposure voltage of a first power level when an inside or an outside guide groove adjacent to the pre-pits is exposed and a guide groove exposure voltage of a second power level when a guide groove not adjacent to the pre-pits is exposed. The modulator modulates a laser beam for exposing the guide groove in accordance with the guide groove exposure voltage. In this way, the groove shape of the guide groove adjacent to the pre-pits and that of the guide groove not adjacent to the pre-pits are made uniform.

Method for exposing optical master disk

An apparatus for optical master disk exposure for exposing guide grooves and pre-pits with laser beams has a reference signal generator which generates a reference signal for being supplied to a groove reference voltage generator that generates a groove reference voltage according to the reference signal. A pre-pit designation signal generator generates a pre-pit designation signal designating formation of the pre-pits. A pre-pit region voltage generator generates a pre-pit region voltage with a power of level of 70 to 75% of the groove reference voltage according to the pre-pit designation signal. A bias voltage generator generates a bias voltage with a power level of 80 to 90 of the groove reference voltage when no pre-pit is formed according to the pre-pit designation signal. A guide groove exposure voltage supplier adds together the groove reference voltage, the pre-pit region voltage and the bias voltage and outputs a guide groove exposure voltage to a laser beam modulating means which modulates the laser beams according to the guide groove exposure voltage received from the guide groove exposure voltage supplier. The guide grooves are uniformly formed thereby enabling the reduction of cross-talk.

A magneto-optical disc recording apparatus is constituted by a pre-output detection circuit, a post-output detecting circuit, a pre-output pulsing circuit, a post-output pulsing circuit, a logical operation circuit, a recording data memory circuit and a comparison operation circuit. An optical head is configured by arranging photodetectors in an array so that the light returned from the areas in the medium on which the laser beam is irradiated can be separately detected at two or more positions along the direction of advance of the laser beam.
