Abstract: In an insulation type AC-dc converter in which input current from a commercial power supply is converted to obtain insulated direct current, the overall efficiency is raised and the structure is simplified. A multi-resonance type half-bridge DC-DC converter having an insulation transformer T is used as a first converter, and a boosting chopper circuit for power factor improvement is used as a second converter. Hence through multi-resonance operation, increases in losses can be suppressed even when the switching frequency is raised, and because a half-bridge circuit is used, switching elements and similar with lower voltage ratings can be employed, whereby overall efficiency can be increased.

Abstract: Light outputs from many LEDs are uniformized and power consumption required for such uniformizing is suppressed, in an LED lighting circuit to be used for illuminating apparatus and the like. Currents flowing from a DD converter to an LED module are detected by a current detection resistor and compared with a reference voltage (Vref) from a reference voltage source by a comparison circuit. Corresponding to the comparison results, a control circuit controls the DD converter, and the currents flowing to the LED module are controlled to be constant currents at the same time. Furthermore, in LED load circuits configuring the LED module, control elements configuring a current mirror circuit are arranged in series, a corresponding control element is permitted to have a diode structure by having a circuit with the highest sum of the LED ON voltages as a reference, the flowing current values of the control elements of the remaining circuits are interlocked, and the LED load circuits are balanced.

Abstract: A photochemical reactor element containing microcapsulated TiO2 photocatalyst particles dispersed in a polysiloxane matrix is disclosed. The polysiloxane matrix has an oxygen gas permeability not less than 1×10−14 mol·m·m−2·s−1·Pa−1. The photochemical reactor element is produced by dispersing the microcapsulated or naked TiO2 photocatalyst particles in a hydrolyzate-polycondensate sol of a trialkoxysilane or a mixture thereof with a tetra- and/or dialkoxysilane and then shaping the dispersion into the element. The naked TiO2 photocatalyst particles in the element are microcapsulated within a porous silica shell layer in situ by irradiating the element with UV radiation.
