Abstract: An anti-counterfeit latent image formation object for bills, bank notes, security papers, credit cards, passports, valuable printing matters, and the like including a main body, a plurality of projections and/or recesses formed on the main body in such a manner as to exhibit various kinds of patterns, in which the various kinds of patterns include straight image lines forming a pattern, a relief pattern, or a combination of the pattern and the relief pattern; a plurality of straight lines printed on at least one surface of the main body at predetermined intervals, the straight lines being printed in a different color from that of the main body itself. The patterns consisting of letters, figures, etc. can be visually recognized only when the anti-counterfeit latent image formation object is viewed from an adequate angle. A method for making the anti-counterfeit latent image formation object is also disclosed.

Abstract: A multistage amplifier (1) consists of unit amplifiers (1a-1c) connected in series. A .lambda./2 strip line (20) is connected in parallel to the last stage unit amplifier (1c), so that a signal may bypass the last stage unit amplifier. When the last stage unit amplifier is disenabled, the signal bypasses the last stage unit amplifier, and the output power is reduced without a decrease of power efficiency in the other unit amplifiers. When all of the unit amplifiers are enabled and the strip line is grounded at the central point thereof, the output power is increased.

Abstract: A liquid crystal display device, wherein a fill port for inserting a liquid crystal composition thereinto is sealed by using a photo-setting resin composition comprising an acrylic or methacrylic type resin as a major resin component and two or more photosensitizers different in quality, is excellent in reliability and the sealed portion of the fill port can sufficiently and uniformly be cured both in surface and inner portions by irradiation of light in a short time.

Abstract: A multi-layer liquid crystal panel for a liquid crystal display device having stacked light transmitting substrates of different sizes is disclosed. A retainer is disposed at a position directly beneath a sealing member which seals a first substrate and a second substrate, between the second substrate and a third substrate. The retainer is applied to the substrates simultaneously with the application of the sealing member. The first, second and third substrates are stacked one on the other and pressed to form a multi-layer panel. By virtue of the retainer, the gaps between the respective substrates are maintained uniform over the display area.

Abstract: A transparent electroconductive film formed on a glass substrate by a special wettability-improving treatment of the surface portion of a SiO.sub.2 film formed on the glass substrate, followed by coating with an indium complex solution, drying, irradiation with ultraviolet light and calcination, has low sheet resistance, good film properties and high quality.

Abstract: A liquid crystal display element includes a pattern display section defined by the superposing portions of upper and lower display electrodes. In a non-display area around the display section, upper and lower non-display electrodes are arranged so that the superposing portion thereof partially or entirely covers the non-display area. In operation, a non-selective voltage is always applied across a liquid crystal at the superposing portion of the upper and lower non-display electrodes.

Abstract: A liquid crystal display element characterized by having an orientation controlling film containing a uniformly dispersed spacer therein on one inside surface of electrode substrates shows only a slight deviation in changes of the distance between the two electrode substrates even in the case of a large-size element. Such a liquid crystal display element can be produced by coating a mixture of a film forming material, a spacer and a solvent on one surface of an electrode adhered to one substrate, dried and baked, followed by conventional display element producing procedures.

Abstract: A process for the manufacture of a liquid crystal container for a liquid crystal display element, which process comprises the steps of applying a low-melting glass frit paste to at least one of a pair of glass substrates, subjecting this glass substrate to primary firing in an open condition in which the paste is in no contact with any matters, and while holding the pair of the glass substrates in their accurate relative positions, subjecting the glass substrates to secondary firing to seal the pair of the glass substrates with the glass frit. The process preferably comprises the step of applying, prior to the step of secondary firing, a low-melting glass frit paste to one of the glass substrates so as to reliably hold the pair of the glass substrates in the accurate relative positions.

Abstract: The display apparatus comprises a liquid crystal display element, a circuit board and electroconductive members interconnecting them. External terminals are formed on one substrate of the display element and input terminals are formed on the circuit board. The external terminals are electrically and mechanically interconnected by rigid electroconductive members through conductive films.

Abstract: A pair of insulating substrates are maintained at a definite spacing, at least one of the substrates being transparent and provided with transparent electrode, the periphery of the substrates is sealed except a liquid crystal inlet opening to form a cell, a liquid crystal is filled into the cell and the opening is sealed with a molten solder in an inert atmosphere.

Abstract: A field effect type liquid crystal display element is provided with polarizing plates. Each polarizing plate comprises a polarizing film consisting of polyvinyl chloride and supporting members bonded to both sides of the polarizing film and an ultraviolet ray absorbing agent is incorporated to either one of the polarizing film and the supporting members.

Abstract: In a liquid crystal display cell wherein two glass plates are sealed to a peripheral sealing member provided with a liquid crystal inlet port, the peripheries of the glass plates generally project slightly beyond the periphery of the peripheral sealing member thus forming a shallow groove. Low melting point glass filler is filled in the groove about the inlet port. A metal layer is applied onto the filler and finally a solder layer is applied onto the metal layer to seal the inlet port.
