摘要:
The present invention relates to a method for producing a formyl group-containing porous base matrix, comprising the steps of introducing a spacer in a formyl group-containing porous particle; and then oxidizing the spacer with periodic acid and/or a periodate, to transform the part of the spacer into a formyl group; wherein the formyl group content in the porous particle after introduction of the spacer is not more than 3 μmol per 1 mL of the porous particle. Also, the present invention relates to a method for producing an adsorbent, comprising the step of immobilizing an amino group-containing ligand on the formyl group-containing porous base matrix. According to the present invention, a formyl-group containing porous base matrix and an adsorbent produced from the porous base matrix of which adsorption amount is high and which is has high strength and of which ligand is difficult to be leaked are provided.

摘要:
A switching power supply device has a large load power supply line for a CRT circuit, to and from which a dummy resistor for voltage stabilization is connected and disconnected by a switch. In standby state, a control unit turns off the switch to disconnect the dummy resistor from the power supply line. When receiving a power supply ON command input by a user operating a remote control, the control unit turns on the switch to connect the dummy resistor to the power supply line. At a predetermined time after the dummy resistor connection, the control unit makes a regulator active to start providing voltage to a video/audio signal processing circuit with sufficient current providable thereto. This enables to reduce power consumption of the power supply line with the dummy resistor, and to prevent problems caused by insufficient current in transient state from standby state to power supply ON state.

The objective of the present invention is to provide a method for easily producing a porous cellulose particle which can be used as an adsorbent for various substances in a safe manner without using a highly toxic solvent such as a calcium thiocyanate solution. In addition, the objective of the present invention is to provide a porous particle produced by the production method, an adsorbent which contains the porous particle and by which a highly pure protein can be efficiently purified in a safe manner, and a method for purifying a protein by using the adsorbent. The method for producing a porous particle according to the present invention is characterized in comprising the steps of preparing a solution containing cellulose and an ionic liquid; preparing a dispersion by dispersing the obtained cellulose solution into a liquid, wherein the liquid is not compatible with the ionic liquid; and coagulating the dispersion by bringing into contact with an alcohol or an alcohol aqueous solution in order in order to obtain the porous particle.
