An organic EL device includes a substrate, a first colored layer, a first luminescence element having a first pixel electrode, a reflection layer, and an insulation layer which overlaps a second portion without overlapping a first portion of a first pixel electrode. Light emitted from the first luminescence element includes a first light emitted from a region overlapping a first portion and a second light emitted from a region overlapping a second portion, and a film thickness of an insulation layer or optical characteristics of the first colored layer are set so that the first light is transmitted through the first colored layer more than the second light is.

In an ion trap device including: a plurality of electrodes enclosing an ion trapping space for trapping ions; an RF driving circuit for generating an RF driving voltage; a resonant circuit for amplifying the RF driving voltage and applying an RF high voltage to at least one of the plurality of electrodes; and a tuning circuit for adjusting a resonant frequency of the resonant circuit while keeping the amplitude of the RF high voltage constant, the method of adjusting the ion trap device according to the present invention includes the steps of: adjusting a resonant frequency of the resonant circuit to a frequency of the RF driving voltage; and shifting the resonant frequency of the resonant circuit so that the RF driving voltage increases by a predetermined constant ratio. According to the ion trap device and its adjusting method of the present invention, the phase difference between the RF driving voltage of the RF driving circuit and the RF high voltage, θ, is adjusted to the same value in plural devices even if the parameters of various elements constituting the resonant circuit, such as the inductance or the equivalent resistance, are slightly different from device to device. Thus the influence of the change in the resonant angular frequency Δω when the amplitude of the RF high voltage is changed to the phase difference θ, Δθ, is the same among devices, and the qualities, such as the mass resolution, of all the devices are always set at their optimal, even if the same parameter values are used to determine operation timings of the device.

This invention discloses an infrared thermometer for ear or skin temperature. The infrared thermometer comprises a body, an infrared sensing element, and a heat dissipating means. The heat dissipation means is provided behind or below the infrared sensing element for urging the air flowing in and out of the body, so as to contribute better heat dissipation and air circulation around the infrared sensing element. Hence the accuracy and stability of the infrared thermometer are improved.

In a beam-spot position compensation method for use in an optical scanning device which scans a surface of a photosensitive medium by a light beam emitted by a light source, a plurality of sections are defined by dividing a scanning region on the scanned surface. An emission timing of the light beam for every section is adjusted so that a spacing between beam-spot positions corresponding to pixels of start and end of each section is changed by a predetermined amount. The sparseness or denseness of beam-spot position spacings of the plurality of sections in the whole scanning region is compensated.

The invention provides a detection device and a method of making a gamma detection image.The detection device comprises a gamma camera and an additional camera, that can make an image of the object outside the gamma detection space. Through correlating the positions of the object with respect to the first and the second camera, the images therefrom may also be correlated.The correlation of the images allows quick and accurate navigation through the object.
