An electric motor drive device that includes an electric motor, a main circuit, a current sensor, and a control unit. The electric motor has a plurality of windings. The main circuit transforms power into AC power and supplies the AC power to each of the plurality of windings. The current sensor detects a load current flowing through each of the windings. The control unit controls the main circuit on the basis of a current value detected by the current sensor and controls an amount of power to be supplied from the main circuit to the electric motor on the basis of an amplitude of the load current associated with detection of an undervoltage state of the AC power supply in a state in which the main circuit uses conversion rule in which an index value for the amplitude of the load current flowing through the plurality of windings is defined.

A carrier recovery circuit, adapted to a demodulation circuit according to a quasi-coherent detection method for generating baseband signals by way of quadrature detection on a received signal having an intermediate frequency, rotates phases of baseband signals; detects a phase error and an amplitude error; controls a bandwidth of a loop filter based on its difference, eliminates a high-frequency component from the phase error; and performs phase rotation based on the phase error eliminating its high-frequency component. It expands the bandwidth of the loop filter when a difference between the phase error and the amplitude error is greater than a predetermined threshold, whilst reducing bandwidth of the loop filter upon determining that the amplitude error decreases due to a reduction of the bandwidth of the loop filter. This optimizes the bandwidth of the loop filter to follow variations of the C/N ratio of the received signal, improving bit error rate.

A power limiting circuit includes: a maximum value prediction filter section (MVPFS) interpolating data of one branched digital input signal; a maximum value detection section detecting maximum value of an output of the MVPFS and a time detection position thereof every constant period; a threshold subtraction section subtracting a threshold from detected maximum value and outputting a peak signal (zero when the subtraction result is negative); a coefficient selection section weighting the peak signal according to time detection position; a complex filter section limiting the weighted peak signal within a band of the input signal; a filter coefficient calculation section calculating filter coefficients of the complex filter section; a delay adjustment section delaying another of the branched input signals by a time period required for calculating the band-limited peak signal; and a subtraction section subtracting the band-limited peak signal from the other of the branched input signals subjected to delay.

A bathing preparation comprising an alkyl phthalide and/or an alkoxy phthalide and/or an alkylidene phthalide optionally together with carbon dioxide gas or a material capable of generating carbon dioxide gas and an extract of a plant belonging to the family Umbelliferae is disclosed. This bathing preparation has excellent effects of warming, retaining the warmth and accelerating blood circulation.

Bathing preparation

A bath additive composition comprises an aluminum salt and a carbonate and makes the pH of bath water 8 or higher but less than 9 when the bath additive composition is dissolved in the bath water. The bath additive composition does not damage bathtubs, bath water heating devices, or the skin of users, provides a refreshing feel to the skin after bathing, and has an excellent ability of suppressing perspiration.

Bathing preparations comprising a soluble aluminum carboxylate exhibit excellent dissolvability into bath water, and give a refreshing sensation to users during bathing and after bathing.

Soluble aluminum carboxylate bathing preparation

Surfactant-containing seamless capsules of the present invention have an inner layer and an outer layer having a film-forming material. The inner layer contains an oily component and a surfactant component. Such surfactant-containing seamless capsules are produced using in multiple nozzle of triple or more having a sequentially increasing diameter. Since the capsules are excellent in emulsive dispersibility of the content liquid and surfactant dispersibility and solubility in the oily component, they can be used in pharmaceuticals, foods, luxury foods, bath additives, detergents and other fields.
