  • Patent number: 7291628
    Abstract: The invention is based in part on the discovery that nonselective ? agonists that possess ? receptor-mediated effects in addition to their ? agonist effects can decrease cocaine self-administration more effectively and with fewer undesirable side effects than can highly selective ? agonists. The invention includes a number of new compounds having both nonselective ? opioid receptor agonist activity and additional activity at ? opioid receptors. These compounds are useful for the treatment of cocaine abuse, and can also be radiolabeled for use as imaging agents, e.g., the N-fluoroalkyl and iodoalkyl derivatives can be used, respectively, for positron emission tomography (PET) and single photon computed tomography (SPECT) brain imaging.

  • Publication number: 20050260028
    Abstract: A Spray Controlled Cleaning Apparatus provides a means for users of the spray controlled cleaning brush to clean and brush with a cleanser liquid without the need to carry another container for the liquid cleanser. The present invention combines the advantages of having an easy to use cleaning brush with a reservoir capable of holding the appropriate cleaning cleanser solvent for the particular cleaning task, and having the advantage of liquid ejection in a controlled spray pattern and amount desired. The operation of the spaying pump body is accomplished by pressing the pressing button, the pressure increases, the liquid within the pump body, which was pressured by the piston, is prevented from entering into sucking head by the one-direction-only valve and is sprayed out through the spraying head of the pump body. By releasing the pressing button, the piston returns to its original position under the effect of the spring. The pressure of the liquid within the pump body decreases.

  • Patent number: 6842466
    Abstract: A semiconductor wafer with variable transmittance, serves as a saturable absorber for performing passive Q-switching in a laser system to produce laser pulses having defined output characteristics. By translating or rotating the semiconductor saturable absorber, loss properties of a laser cavity may be altered. In this manner, the output characteristics of the laser pulses can be varied without changing other parameters of laser operation. The output characteristics may include pulse duration, pulse repetition rate, peak power and average output power of the laser pulses. The semiconductor wafer can be made of doped or undoped GaAs, AlGaAs, InP, etc. Furthermore, the tunable Q-switch may simultaneously serve as an output coupler for the laser cavity.
