A homeotropic liquid crystal display device compensated for the anisotropy of the homeotropically oriented nematic liquid crystal layer, by anisotropy compensating means comprising at least two anisotropic (e.g. uniaxial) films having their optic axes disposed to form a right angle in a plane parallel to the substrate to form an optically negative activity in the direction perpendicular to the substrate. This optically negative activity is so selected to compensate the positive optical anisotropy of the nematic liquid crystal when oriented homeotropically in the absence of electric field.

Homeotropic liquid crystal display device

A planar heater for a liquid crystal element comprises a thin metal plate having a relatively high specific resistance such as stainless, nichrome, nickelchrome iron alloy, etc. The thin metal plate is subjected to etching-working to form a mesh-like heat generating body, opposite ends of which are provided with terminal portions for connection into an elecrtrical circuit.

Electric discharge lamp

Fluorescent lamp

A method for making a fluorescent lamp from a pair of molded, flat glass shells. Substantially semi-circular recesses are formed on each shell on bonding surfaces thereof opposite semi-circular recess formed on the other glass shell, so that when the shells are bonded together, a circular orifice is formed on the lamp. An exhaust tube is provided, and a stem is affixed to an end of the exhaust tube, and an electrode filament and a getter plate are secured to the stem. The shells are bonded together with a glass adhesive and simultaneously therewith, the exhaust tube is sealed into the orifice so that the getter plate and the electrode filament thereof are disposed within the space between the bonded shells. The gases within the space between the shells are exhausted and mercury and an inert gas are injected into this space. The exhaust tubes then are sealed.

Method for making a fluorescent lamp

A flat type fluorescent lamp comprises a pair of rectangular dish-shaped halves connected together to form a rectangular hollow body, and discharge electrodes disposed at both ends of the rectangular body. Voltage supply terminals for the electrodes and an exhaust pipe for exhausting or substituting another gas for the air in the fluorescent lamp are situated at one end only of the rectangular body.

Flat fluorescent lamp

A fluorescent lamp constituted by joining a pair of shells of glass that at least one of the shells is molded. A recess is formed on a portion of the jointing surface of the shells so as to become circular when the shells are overlapped each other. An exhaust tube and lead-in wires of electrode stem are hermetically fixed in the recess by adhering or by welding. An anode getter plate is arranged independently from an electric circuit including an electrode filament.

An indicating device with a flat fluorescent lamp which comprises a fluorescent lamp having flat side surfaces and one or more indications formed on the side surfaces of the fluorescent lamp. The indicating device can be further provided with an ornamental frame which is attached to the outer periphery of the fluorescent lamp and a mounting base which is attached to one side of the ornamental frame and holds therein a discharge circuit including a stabilizer and a glow lamp for the fluorescent lamp.

Indicating device with flat fluorescent lamp

A flat type fluorescent lamp comprises a molded plate glass in the form of an upside down dished plate and a flat plate sealed to the dished plate along the peripheral portions thereof. A pair of electrodes are mounted on the flat plate glass, spaced from the flat plate glass, through stems or connector pins and are sealed in the fluorescent lamp body. The fluorescent lamp requires no base so that the overall length thereof may be reduced.

Flat type fluorescent lamp

A flat type of fluorescent lamp having a pair of shells. One of the shells has a surface which extends outwardly from the joint portion of the shells, at both ends thereof. A pair of lead-in wires for supporting a discharge electrode are disposed on the outwardly extending surface of the shell and are connected to electrode terminals which correspond to the pair of lead-in wires.
