摘要： A circuit device (e.g. mounted on a printed circuit board) is connected to a data network, to which network are also connected a plurality of other circuit devices under power. On removal of such a circuit device, the output driver connecting the circuit components of the output device to the communications bus of the bus network is first disconnected from power, and only when its disconnection is stable is the device withdrawn. A control device of the circuit device is connected to the control bus of the data network, and before power is disconnected from the output driver, the control device signals to the network so as to prevent other circuit devices connected to the network from signalling on the network. Effectively, the circuit device to be removed "occupies" the bus. This occupation is maintained until the disconnection of the output driver is stable, and then the circuit device can be removed from the network. Similarly, on insertion, the network is first occupied before power is connected to the output driver. In this way, it becomes possible to prevent faults due to missignalling between the other circuit devices connected to the network when one circuit device is inserted or removed.

摘要： A duplex transmission control system having active and inactive systems for totally controlling a looped transmission line on which computers and terminal devices are connected through respective stations. Each transmission control unit is operable to transmit and receive specific data related to the priority level specified for each unit. Each transmission control unit suspends the transmission of the clock for a certain period in response to the detection of the clock suspension, then transmits the specific priority data. When a transmission control unit detects its own transmitted signal, it is designated as the active system when another transmission control unit receives the signal defining the active system, it is designated as the inactive system.

摘要： The reliability of a semiconductor device having an embedded wire in the lowest layer wire is improved. In a main surface of a semiconductor substrate, MISFETs are formed and over the main surface, insulating films 10, 11 are formed. In the insulating films 10, 11 a contact hole is formed and a plug is embedded therein. Over the insulating film 11 in which the plug is embedded, insulating films 14, 15, 16 are formed and an opening is formed in the insulating films 14, 15, 16 and a wire is embedded therein. The insulating film 15 is an etching stopper film when etching the insulating film 16 in order to form the opening, containing silicon and carbon. The insulating film 11 has a high hygroscopicity and the insulating film 15 has a low moisture resistance, however, by interposing the insulating film 14 therebetween and making the insulating film 14 have a higher density of the number of Si (silicon) atoms than that of the insulating film 11, an electrically weak interface is prevented from being formed.

摘要： A liquid crystal display apparatus which have a circular polarizer and a liquid crystal display in a stack. The liquid crystal display has a chilral nematic liquid crystal layer between substrates, and on the mutually opposite sides of the substrates, electrodes and aligning layers are formed. The liquid crystal switches between a planar alignment state and a focal-conic alignment state depending on the voltage applied thereto through the electrodes. In a planar state, light reflected by the electrodes is absorbed by the circular polarizer, and a black display is made. In a focal-conic state, light reflected by the electrodes passes through the circular polarizer, and a white display is made. The liquid crystal is driven by a chain of voltage pulses including a reset step of resetting the liquid crystal to a homeotropic state, a selection step of selecting the alignment state of the liquid crystal under zero-volt application and an evolution step of causing the liquid crystal to evolve to the selected alignment state.

摘要： A liquid crystal light modulation element includes a liquid crystal layer between first and second substrates. The liquid crystal layer includes a liquid crystal material exhibiting a cholesteric phase having a peak selective reflection wavelength in a visible wavelength range. When the liquid crystal layer is in the selective reflection state, it has pixel regions near the first and second substrates. The liquid crystal domains in the pixel regions near the first substrate are in a mixed state of polydomain and monodomain states. The liquid crystal domains in the pixel regions near the first substrate have a first ratio between the liquid crystal domains taking the polydomain and monodomain states. The liquid crystal domains in the pixel regions near the second substrate have a second ratio between the liquid crystal domains taking the polydomain and monodomain states. The first ratio is different from the second ratio.

摘要： Disclosed is a reflective type multilayer liquid crystal display having a blue liquid crystal light control layer, a green liquid crystal light control layer, and a red liquid crystal light control layer stacked in this order from a viewing side. The half width of a reflection spectrum of any of the liquid crystal light control layers is larger than that of the adjoining liquid crystal light control layer on the viewing side. Further, the maximum reflectance of the reflection spectrum of any of the liquid crystal light control layers is higher than that of the adjoining liquid crystal light control layer on the viewing side. In one embodiment, the chromaticity coordinate position, in the XYZ colorimetric system, of a color displayed when all the liquid crystal light control layers are in a state of reflecting at the maximum reflectance is present in a range within a distance of 0.02 from the chromaticity coordinate position of the standard white point.
