The light emitting device includes a non moisture permeable translucent substrate 11, a light emitting laminated body 13 provided on the translucent insulating substrate 11 including an organic EL light emitting layer 16, a first electrode layer 15 laminated thereon, and a second electrode layer 17. The light emitting device further includes a non moisture permeable sealing wall 14, which is provided on the substrate 11 by forming a space covering the light emitting laminated body 13 without striding over the first and second electrode layers 15, 17 of the light emitting laminated body 13, and connecting terminals 23 which are provided by penetrating the sealing wall or the substrate to supply electric power to each electrode layers 15, 17 of the light emitting laminated body 13.

Abstract: A light emitting apparatus having a large quantity of light per space necessary for installation, which allows easy adjustment of the directivity of light emission and easy arrangement of the color of emitted light and has a high light emitting efficiency, is achieved by a light emitting apparatus, which is comprised of a moisture impermeable substrate having a warped configuration, an electro-luminescent light emitting laminated body formed on the inner surface of the warped substrate having such constitution that, from the warped substrate side, at least a first electrode layer, a light emitting function layer and a second electrode layer being laminated in this order, a moisture impermeable opposing substrate joined in an impermeable manner at the edge portion or in a region adjacent to the edge portion of the warped substrate and electrical connection terminals connected to each of the electrode layers of the electro-luminescent light emitting laminated body for externally supplying electrical energy to e

Abstract: A cassette with a loosening prevention mechanism includes a cassette case rotatably supporting reels including a strip of medium wound therearound. Each of the reels has, at its one end, a rotation prevention portion and an outer shaft portion and, at its other end, an inner shaft portion. A resilient member is integral with the cassette case. The reel has an inner end in contact with the resilient member and is pressed toward the outer shaft portion by the resilient member. A rotation prevention mechanism is operative when the rotation prevention portion of the reel is brought into engagement with a rotation stop portion formed on an inner peripheral wall of said cassette case, and inoperative when a force applied from the outer shaft portion toward the inner shaft portion of the reel is greater than a pressing force by the resilient member.

Abstract: A sintered body for a humidity sensor is formed by baking a blend at 1,000.degree. to 1,400.degree. C., the blend comprising ZnO, Cr.sub.2 O.sub.3, V.sub.2 O.sub.5 and M.sub.2 O where M.sub.2 O is at least one metal oxide selected from Li.sub.2 O, Na.sub.2 O and K.sub.2 O. A pair of electrodes are each attached to the corresponding surface of the sintered body to obtain a humidity sensor of metal oxide which is relatively low in its resistive value and stable in its aging characteristic.

Abstract: A voltage-nonlinear resistor having a good polarity characteristics is manufactured by sintering a composition containing metal zinc, zinc oxide and at least one oxide selected from the group consisting of nickel oxide, zirconium oxide, yttrium oxide, hafnium oxide and scandium oxide, each component being contained in an amount within a specific range.

Abstract: A method of manufacturing a voltage-nonlinear resistor which has a substantially symmetrical voltage-current characteristic and a large voltage-nonlinearity coefficient and which is thus well resistant to surge voltage. The method comprises: preparing a ZnO-based composition containing metal zinc, at least one metal oxide such as bismuth oxide and at least one spinel type crystalline compound such as spinel type crystalline chromium compound, shaping the ZnO-based composition to form a body, and sintering the body of composition in the air at 1,000.degree. C. or more.

Abstract: A gas detecting element comprising a hollow cylindrical insulative body, a pair of electrodes provided on the outer periphery of the insulative body, a gas detecting body covering up the outer periphery of the insulative body and the electrodes, a catalyst layer made of a catalytic material and coated on said gas detecting body, thereby covering up the surface of said gas detecting body, and a heater disposed in the hollow of the insulative body. When the gas detecting element comes into contact with a gas, the surface resistance of the gas detecting body varies, thereby detecting the gas.

Abstract: A gas-sensing material for detecting the presence particularly of hydrocarbon gases which is characterized by being formed of a sinter containing 20 to 99.85 mol % of ZnO, 0.1 to 50 mol % of MgO and 0.05 to 30 mol % of Me.sub.2 O.sub.3 (Me denotes at least one element selected from the group consisting of gallium (Ga), boron (B), indium (In), iron (Fe), aluminium (Al) and chromium (Cr)), or another sinter prepared by blending 0.01 to 10% by weight of platinum (Pt) to the above-mentioned composition.
