Abstract: The invention is directed to a process for making screen-printable getter composition comprising: (a) glass frit; and (b) pre-hydrated desiccant material; dispersed in (c) organic medium. The present invention further relates to a getter composition utilizing low-softening temperature glasses comprising, based on weight %, 1-50% SiO2, 0-80% B2O3, 0-90% Bi2O3, 0-90% PbO, 0-90% P2O5, 0-60% Li2O, 0-30% Al2O3, 0-10% K2O, 0-10% Na2O, and 0-30% MO where M is selected from Ba, Sr, Ca, Zn, Cu, Mg and mixtures thereof. The glasses described herein may contain several other oxide constituents that can substitute glass network-forming elements or modify glass structure.The desiccant material is pre-hydrated to reach its saturation level of moisture absorption. The process of pre-hydration can be done by exposing the desiccant in a normal temperature/humidity environment of for example, 25° C. and 50-60% RH. For 24 to 48 hours or up to the time when weight gain (due to moisture absorption) stops increasing. An accelerated hydration process in a chamber with higher than normal humidity level (i.e. 50% Relative Humidity) is also applicable to shorten the time of exposure to fully hydrate the desiccant material.

Abstract: A radiation pulse, such as from a solar simulator, is spectrally analyzed over a selected sampling pulse that is shorter in duration than the radiation pulse and is timed to begin after the start of the radiation pulse. A deformable membrane mirror is controlled to function as a high speed shutter in the path of the radiation pulse. When not deformed, the mirror reflects the radiation pulse into an optical instrument, such as a spectroradiometer. A sampling pulse is generated for a selected time after the start of the radiation pulse and is applied to the mirror to ensure total reflection of the radiation pulse only for the duration of the sampling pulse. Controls are provided to adjust the start time and duration of the sampling pulse, and to adjust the sensitivity of sensing the start of the radiation pulse.

Abstract: A reflective optical position or object detector, containing a light source (LED) and detector (phototransistor) is placed proximate to an acoustic membrane such that the output of the detector produces an electric signal corresponding to the motion of the membrane toward and away from the detector. Groups of these detectors can be placed at different locations under a single membrane to reproduce the frequency and harmonic content of the motion of the membrane at those locations, and the signals from each can be combined in variable proportion to a resultant electrical signal. These groups can be bounded by isolating frames and several bounded groups can be placed under a single membrane, or be covered by separate membranes. The groups with their bounding frames can be moved toward or away from the membrane, placing more or less tension upon the membrane, thereby altering the harmonic and frequency content of its vibration.

Abstract: To detect a faulty operation in a non-contact switch, a pulse signal is applied to the light emitting element of non-contact switch. The thus input pulse signal is compared with an output signal generated by a light receiving element of the non-contact switch. The faulty operation of the non-contact switch is discriminated in accordance with the thus compared input and output signals. Also to detect a faulty operation of the non-contact switch, a switch assembly includes a main push-button and an auxiliary push-button concentrically located over and within the main push-button. When the main push-button operates properly, the blocking members associated with the main push-button and the auxiliary push-button are displaced together. On the other hand, when the main push-button malfunctions, the light blocking member of the auxiliary push-button blocks the passage of light within the non-contact switch. Thus, an erroneous operation resulting from jamming of the main push-button is prevented.
