摘要:
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 X-ray computerized tomographic (CT) apparatus capable of facilitating alignment of focal spot position at the time of replacing an X-ray tube anew and capable of easily correcting the focal spot position even when the focal spot position of the X-ray tube is deviated. Thereby, the focal spot position of the X-ray tube remains fixed in a predetermined position. The X-ray computerized tomographic (CT) apparatus includes an X-ray tube which is freely movable in at least one of a horizontal direction and a vertical direction; a detection unit for detecting a dislocated degree of the focal spot position of the X-ray tube; and a controlling unit for automatically controlling the focal spot position of the X-ray tube based on data obtained from the detection unit so that the focal spot position of the X-ray tube remains fixed in a predetermined position. In a case where the CT apparatus is used for a helical scanning operation, the detection unit may further include a detection timing controller for controlling an instance of detection and alignment of the focal spot position by utilizing only an output of the X-ray amount detected at a predetermined position of a gantry.

摘要:
A heat pump hot-water supply device includes: a tank; a refrigerant circuit having a water heat exchanger; water conduits; an electrolysis device having an electrode pair provided in a water channel upstream of the water heat exchanger, in a flow channel of water that includes the water conduits; and a control unit that executes a reversal initial operation of reversing the polarity of the electrode pair in the electrolysis device, and discharging, at a position upstream of the water heat exchanger, water that is treated in the electrolysis device during a period after polarity reversal until a predetermined condition is satisfied.
摘要:
An external power source is connected to an adapter input terminal (first terminal). A battery is connected to a path input terminal (second terminal). A selection circuit (a first switch, a second switch, a logic circuit compares the input voltage input from the external power supply with the battery voltage, and selects one of the two. The voltage thus selected by the selection circuit is output to an external load circuit via a system power supply terminal. A charging circuit charges the battery using the input voltage supplied from the external power supply.
摘要:
A bias current source generates a constant current Iref by applying to a current-generating resistor a voltage proportional to a thermal voltage Vt. A first bipolar transistor and a second bipolar transistor are disposed in series on the path of the constant current which is generated by the bias current source. A third bipolar transistor forms a current mirror circuit with the second bipolar transistor. A fourth bipolar transistor has a base connected to the base of the first bipolar transistor and has an emitter connected to a temperature-compensating resistor. The constant current circuit outputs a sum of the collector currents of the third bipolar transistor and the fourth bipolar transistor.
