  • Patent number: 11543385
    Abstract: An ion mobility filter is disclosed. The present invention relates to but not exclusively a field asymmetric ion spectrometry filter. For example, we describe an ion filter for filtering ions in a gas sample. The ion filter is comprised of a plurality of electrodes, a first ion channel, and a second ion channel. The first ion channel filters ions from a target chemical in the gas sample, defines a gap between a first pair of electrodes in the plurality of electrodes, and has a first ion channel gap width. The second ion channel filters ions from the target chemical in the gas sample, defines a gap between a second pair of electrodes in the plurality of electrodes, and has a second ion channel gap width. The first ion channel gap width is greater than the second ion channel gap width.

  • Patent number: 7106409
    Abstract: A glass substrate of a display panel onto which an organic electroluminescence (EL) element or the like is formed is sealed by affixing the glass substrate and a sealing member such as a sealing glass onto which an adhesive has been applied. During this process, the temperature of the adhesive is controlled by, for example, controlling the temperature of the nitrogen gas to fill a chamber through a temperature adjusting device, so that the viscosity of the adhesive is adjusted. In this manner, quick and precise sealing of the display substrate by the sealing member and the adhesive can be achieved.

  • Patent number: 7042534
    Abstract: Light is input into an incident surface portion from a fluorescent lamp, and most of the light propagates in repetition directions. Since a length of an emission portion of the fluorescent lamp is shorter than that of the incident surface portion, there are areas to which no light propagates and dark portions generate in the repetition directions of a string of prisms. Since these dark portion generate out of the display area, a display quality is improved.

  • Patent number: 6994478
    Abstract: Rotate-and-pull mechanisms for fiber optic modules. The rotate-and-pull mechanisms have a lever-actuator to unlatch and withdraw a fiber optic module from a cage assembly or a module receptacle. The lever-actuator pivotally couples to the fiber optic module so that when lever-actuator is rotated about its pivot point, the lever-actuator causes the second actuator to release the fiber optic module from the cage assembly. The lever-actuator includes an actuating-tab to cause the second actuator to move when the lever-actuator is rotated. By pulling the lever-actuator away from the cage assembly, the fiber optic module is withdrawn from the cage assembly. A belly-to-belly mounting configuration is introduced for the rotate-and-pull release fiber optic modules.
