A retrofit unit which is used for replacing conventional incandescent light bulbs with fluorescent light bulbs in existing lighting fixtures of the ceiling or wall mounted type.

A locking structure of a ceiling lamp for locking a ceiling lamp to a wire winding box comprises a retaining sheet locking to a bottom of a wire winding box and a plug inserting through the retaining sheet. A middle part of the retaining sheet has a positioning hole formed by overlapping a large size hole and a small size hole. A reed has a round buckling surface with a notch. The round buckling surface covers upon the large size hole. One end of the plug is locked with a nut. After the plug pas...

Disclosed is an ultrasonic generating and transmitting apparatus equipped with a transmission section for transmitting ultrasonic vibration from a vibration section. A plurality of linear members for transmitting ultrasonic vibration and binding plates which bind the linear members in such a state as to be apart from one another are provided. The transmission section is comprised of the linear members and the binding plates.

A method and apparatus for improving blood flow to an ischemic region (e.g., myocardial ischemia) a patient is provided. An ultrasonic transducer is positioned proximate to the ischemic region. Ultrasonic energy is applied at a frequency at or above 1 MHz to create one or more thermal lesions in the ischemic region of the myocardium. The thermal lesions can have a gradient of sizes. The ultrasound transducer can have a curved shape so that ultrasound energy emitted by the transducer converges to...

The invention concerns a dyeing composition for keratinous fibres, in particular human keratinous fibres and more particularly hair, comprising a dicationic diazo dye of formula (I), as well as the dyeing composition using same. The invention also concerns the novel compounds of formula (I).

An emulsion hair bleach composition prepared by combining an aqueous oxidizing agent composition, a persulfate composition, and, optionally, a bleach oil composition, in amounts sufficient to provide a mixture containing an active oxygen concentration of about 3 to 5% by weight of the total mixture, a total alkalinity concentration of about 0.7 1.2 meq/gm., and 0.5 20% by weight of the total mixture of an oil having a solubility parameter of 5 12 (cal/cm.sup.3).sup.1/2; an emulsion hair bleach c...

Disclosed are topical leave-on cosmetic compositions, including packaged leave-on compositions, for direct application to the scalp, comprising a) from about 40% to about 99% by weight of a volatile liquid, b) from about 0.005% to about 20% by weight of a skin active agent, and c) from about 0.1% to about 20% by weight of a moisturizing material, preferably a liquid humectant. The composition is a leave-on formulation that is substantially free of cleansing surfactants and is applied directly to...

A method of collection of the fragrance ingredient of fragrant wood comprises extracting an essential oil ingredient by a solvent from the fragrant wood and collecting the fragrance ingredient in a vapor-phase by heating the extract, a perfume composition contains the fragrance ingredient, and a cosmetic contains the fragrance ingredient. The fragrance ingredient is obtained without a burnt smell, and it has an aroma of the fragrant wood.

A method and apparatus detects dew precipitation and determines dew precipitation onset pressure in a sample of formation fluid located downhole in an oilfield reservoir. In a preferred embodiment, the method includes (a) isolating a sample of formation fluid downhole; (b) illuminating the sample downhole with fluorescence excitation light; (c) measuring at least one characteristic of fluorescence short from the sample; (d) reducing pressure on the sample; (e) repeating steps (b) to (d); (f) det...

A system and method is described for using a matched reactance machine power generation system (MRMPGS) to provide a constant-voltage power for an electric distribution system. The system and method include a permanent magnet rotor type machine without a field winding for excitation. This type of machine presents much better reliability, as the excitation of the machine is fixed and achieved by a permanent magnet embedded in the rotor assembly. The voltage regulation is achieved through speed an...
