摘要:
A voltage comparison circuit makes a comparison between a first voltage and a second voltage. A resistor and a constant current source are provided in series between the first voltage and the ground voltage. A comparator receives the second voltage via one input terminal (non-inverting input terminal), and the voltage at a connection node between the aforementioned resistor and the constant current source via the other input terminal (inverting terminal). The first voltage is preferably used as the power supply voltage for the comparator.

The detergent compositions of the present invention comprising a phosphate surfactant and an amidoamine amphoteric surfactant; a hydroxysulfobetaine, aliphatic lactylate, or aliphatic glycolate, have excellent foam characteristics such as foaming property, foaming power, and rapidity of foaming, as well as excellent low-temperature stability, detergency, and mildness to the skin and hair. Therefore, these compositions can be effectively employed for shampoos and cleaning agents for infants which require not only good detergency but also a low incidence of skin irritation.
摘要:
An electrolysis device is configured such that water flowing into a container from an inlet flows from an upstream side to a downstream side in the container and flows out from an outlet. A first electrode pair is arranged on the upstream side than a second electrode pair. In the electrolysis device, in order to suppress a decrease in current density due to electrolyte concentration in the water in the second electrode pair arranged on the downstream side than the first electrode pair, the current density in the second electrode pair is adjusted.

摘要:
A current-voltage conversion circuit which converts a current to be detected into a voltage, includes a detection resistor, amplifier circuit having a first operational amplifier, and an offset adjusting current source having a third resistor and a fourth resistor which are capable of trimming. The offset adjusting current source causes an offset adjustment current to flow in the offset resistor. The current value of the offset adjustment current is controlled by adjusting the resistance of the third resistor and the fourth resistor. A voltage at a node between the first transistor and the second resistor is output.
