Abstract:
The prior art describes the application of mechanical oscillators for the measurement of corrosion and/or deposition. Mechanical oscillators employ the use of resonance parameters, frequency and the quality factor Q, for the measurement of corrosion or deposition. However, the prior art does not consider the required precision for measuring frequency or Q in the presence of noise to make these measurements. In particular, the ability of the mechanical oscillator to measure small amounts of metal loss or deposition is not only dependent upon the mechanical design but is limited by the precision in determining the resonance frequency and Q. The present invention discloses methods for measuring these resonance parameters with a high precision in the presence of noise. This degree of precision is required to maximize the utility of these devices as sensitive probes for corrosion and deposition (fouling) measurement. All of the embodiments described herein employ curve fitting consistent with modeling the mechanical oscillator as a simple harmonic oscillator. This curve fitting procedure, combined with averaging and utilizing signal processing parameters to mitigate noise effects, adds considerable precision in measuring resonance parameters.
Abstract:
The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a gel latex may be formed as a seed particle and then utilized to form latex resins and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the gel latex.

More particularly, imaging members having nano polymeric gel particles embedded into one or more layers of the imaging member that provide for increased mechanical strength and improved wear.
Abstract:
An optical disc drive including a case, a tray, a turntable, a pickup head, a transmission mechanism, and a protecting cover is provided. The tray is movably set inside the case. The turntable is embedded in the tray. The pickup head is movably embedded in the tray. The transmission mechanism is embedded in the tray and connected to the pickup head. And the protecting cover is set on the tray and covers the transmission mechanism. The protecting cover has a protruding structure located on the surface of the protecting cover that corresponds to a non-data area of an optical disc. Moreover, the tray has a protruding structure located on the surface of the tray adjacent to the protecting cover. Furthermore, pads could be substituted for the abovementioned protruding structures.
