The present invention relates to a radiation generating tube. The radiation generating tube includes an envelope including an insulating tubular member having at least two openings, a cathode connected to one of the openings of the insulating tubular member, and an anode connected to the other of the openings of the insulating tubular member. At least one of the cathode and the anode and the insulating tubular member are bonded at a bonded portion with an electrically conductive bonding member; and the bonded portion bonded with the electrically conductive bonding member is coated with a dielectric layer.

A glass layer 103 containing a binder, a laser-light-absorbing pigment, and a glass fit 102 is irradiated with laser light L2, so as to gasify the binder and melt the glass fit 102, thereby fixing the glass layer 103 to a glass member 104. This allows the glass layer 103 fixed to the glass member 104 to let out the binder and enhance the laser light absorptance, so as to yield a uniform state. As a result, fusing glass members 104, 105 to each other with the glass layer 103 having such a stable state interposed therebetween allows the glass members 104, 105 to have a uniform fusing state therebetween.

At the time of temporary firing for fixing a glass layer 3 to a glass member 4, the glass layer 3 is irradiated with laser light L2 having a ring-shaped irradiation region. At this time, in a width direction of the glass layer 3, two peaks M in a beam profile of the laser light L2 respectively overlap both edge parts 3b of the glass layer 3. This allows a center part 3a and each of both edge parts 3b of the glass layer 3 to be irradiated for shorter and longer times with a part having a relatively high intensity in the laser light L2, respectively. As a consequence, the amount of heat input by irradiation with the laser light L2 is homogenized between the center part 3a and both edge parts 3b in the glass layer 3, whereby the whole glass layer 3 is molten appropriately.

The present disclosure provides a display panel and a display device. The display panel includes a first substrate and a second substrate opposite to each other. A sealant is arranged on one of inner surfaces of the first substrate and the second substrate, and a first spacer is arranged between the sealant and the other one of the inner surfaces of the first substrate and the second substrate.

An organic electroluminescent device, a method for preparing an organic electroluminescent device, and a display panel are disclosed. The organic electroluminescent device comprises a conductive layer formed by transparent magnetic conductive particles which are mixed in the sealing layer and stacked on a surface of the first transparent electrode layer. The conductive layer increases the conductive performance while not increasing the thickness of the first transparent electrode layer, thereby avoiding decrease of the light transmittance caused by increase of the thickness of the first transparent electrode layer, and avoiding the problem of voltage drop due to poor conductivity of the first transparent electrode layer, so as to improve the display effect and use stability of the organic electroluminescent device.

A drift tube construction includes a thin wall aluminum tube with a thin wire at its center attached to a terminal. The tube is plugged at both ends. The terminal is embedded at the center of the plug with material insulating it from Drift tube main body. The Drift tube assembly is sealed and filled with a gas mixture. A voltage is applied to the thin wire via the terminal. Current drift tubes employ plastic material to insulate the terminal from Drift tube main body and O-rings to provide a near hermetic seal.
