A method includes for manufacturing a liquid crystal display device includes: a sealant supplying step of supplying an uncured sealant to a first substrate or a second substrate; a dropping step of dropping a liquid mixture of a liquid crystal material and an additive to a region inside the sealant; a bonding step of bonding the first substrate and the second substrate with the sealant and the liquid mixture interposed therebetween to form a bonded substrate; and a curing step of applying the predetermined curing conditions with a voltage being applied to a terminal portion, and thereby curing the sealant and altering the additive to give a pretilt angle to liquid crystal molecules.

Process for producing liquid-crystal display and liquid-crystal panel base material

In a liquid crystal display apparatus in which a liquid crystal domain having radially tilted orientation is formed in a pixel, high-quality reflection display with occurrence of an afterimage being suppressed is attained. The liquid crystal display apparatus of this invention includes a first substrate, a second substrateand a vertically aligned liquid crystal layerplaced therebetween, and has pixels each including a first electrode, a second electrodeand a liquid crystal layer located therebetween. The first substrate includes a reflection layerhaving a concave/convex surface and an insulating layerformed to cover the reflection layer. The first electrodeis placed on the insulating layerand has a shape defined to exert alignment regulating force with which at least one liquid crystal domain having radially tilted orientation is formed in the liquid crystal layer in a voltage applied state. The second substratehas a protrusionprotruding toward the liquid crystal layer in a region corresponding to the liquid crystal domain.

A signal transmission system over building or house wiring includes noise reduction circuit to reduce noise including asynchronous noise and synchronous noise. Received pulses are sampled in a given interval and the number of continous pulses in question during the sampling interval is counted. The pulses in question are ignored as noise if the number of pulse counting is less than a predetermined reference count and the pulses are treated as true signals if the number is more than said reference count.

The present disclosure is directed to an emergency access method in which in the event that an emergency data occurring at a particular terminal is fed immediately to a central system but collides with any emergency data from a different terminal such collision is sensed and a signal in that data is delayed in a random number manner through the use of an appropriate random number generating algorithm in order to avoid such collision within a short length of time.

An optical bar code reader includes a recognition system for recognizing a bar code data even when none of a plurality of scanning beams extend over the entire width of a bar code label. A plurality of incomplete data each of which represents a portion of the bar code label are combined with each other by a composition circuit to get an estimated complete bar code data. A determination system is provided for detecting whether the read out data obtained from any scanning beam corresponds to the entire bar code data. If an affirmative answer is obtained by the determination system, such read out data is directly applied to the associated processing system without activating the composition circuit.
