Abstract: An indicator lamp indicates the status of an electrically-powered load control system by providing dim light when the load power is off and a brighter light when the load power is on.  In another embodiment, the lamp not only provides two levels of light to indicate whether or not power is on, but also provides a repetitive flash when power to the system is being controlled by remote control.  The indicator lamp can also indicate a break in the load circuit.  Depending on the embodiment, the break can cause the lamp to be either off or flashing, regardless of the position of the load power switch. Alternatively, a break in the load circuit can cause the lamp to provide substantially no light if the load power switch is in the "off" position, with full light in the "on" position.

Abstract: ATMOSPHERIC SAMPLING GLOW DISCHARGE IONIZATION SOURCE            ABSTRACT OF THE DISCLOSURE          An  atmospheric  sampling  glow  discharge ionization source that can be used in combination with an analytical instrument which operates at high vacuum, such as a mass spectrometer.   The atmospheric sampling glow discharge ionization source comprises a chamber with at least one pair of electrodes disposed therein, an inlet for  a  gaseous  sample  to  be  analyzed  and  an  outlet communicating  with  an  analyzer  which  operates  at subatmospheric  pressure.    The  ionization  chamber  is maintained at a pressure below atmospheric pressure, and a voltage difference is applied across the electrodes to induce a glow discharge between the electrodes, so that molecules passing through the inlet are ionized by the glow discharge  and  directed  into  the.  analyzer.    The ionization source accepts the sample under atmospheric pressure conditions and processes it directly into the high vacuum  instrument,  bridging the pressure gap and drawing off unwanted atmospheric gases.   The invention also includes a method for analyzing a gaseous sample using the glow discharge ionization source described above.

Title: Microwave heating
Inventor: LORENSON CLAUDE P
IPC: B65D81/34
Filed: 1989-02-13
Granted: 1993-04-27
Abstract: Abstract of the Disclosure A product comprises a shallow container and a load located therein for heating by microwave energy.  This product is designed either to be used with, or itself to incorporate, a structure for generating or enhancing at least one mode of the microwave energy of an order higher than a fundamental mode that is determined by boundary conditions resulting from the lateral dimensions of either the container or the load or both.  The invention resides in controlling the depth of the load in the container in such a manner that, upon irradiation of the product with the microwave energy, the power absorbed by the load from a higher order mode is at or near a maximum value, while preferably the power absorbed by the load from the fundamental mode is at or near a minimum value.  Since uneven heating would ordinarily be associated with the predominance of a fundamental mode, the result of this invention is to increase the intensity of a higher order mode relative to the fundamental mode intensity, and thus provide improved microwave heating uniformity.

Title: Resolution doubling lithography technique
Inventor: JEWELL TATIANA E
IPC: H01L21/027
Filed: 1989-07-25
Granted: 1993-08-24
Abstract: RESOLUTION DOUBLING LITHOGRAPHY TECHNIQUE Abstract A lithography system is disclosed which is capable of doubling the spatial frequency resolution associated with conventional systems. A spatial filter (e.g., 20), positioned to intercept the Fraunhofer diffraction pattern of the mask (e.g., 18) being exposed, is configured to prevent certain orders of the diffraction pattern (in most cases the 0-order and +2nd, 3rd, ... orders) from reaching the wafer's surface. The remaining orders reaching the wafer surface in most cases the + first-order beams) will produce a cos-type interference pattern with a period half of that if the mask grating were imaged without spatial filtering. Therefore, for a system with a given magnification factor m, a mask grating with a period pwill be exposed on the wafer surface as a grating with a period of p'-pm/2. Advantageously, the spatial filtering technique of the present invention allows for a variety of different structures (conventional gratings, chirped and phase-shifted gratings, grids, Fresnel zone plates, etc.), as well as structures of different sizes and orientations, to be included on one mask and transferred to the wafer with asingle exposure cycle.

Abstract: This invention discloses the  use of a dibenzo  cycloheptene derivative, generally known as protriptyline for the treatment of mental  health  problems  in  children,  specifically   Attention Deficit Syndrome or Attention Deficit Disorder.  By administering the correct dosage  of this  drug, children  have shown  improved concentration, improved sleep patterns, less behavioral  problems both in school  and at  home and  an overall  improvement in  the child behavior.  This new use for protriptyline is unexpected and is contraindicated  in  the literature  since  protriptyline  has commonly been used only as a antidepressant for adults and not as a mild  stimulant in  the treatment  of childhood  mental  health problems, such as Attention Deficit Disorder or Syndrome.
