摘要:
An audio visual control apparatus for communication between a master device and a slave device comprises a master AV center, at least one slave device, a digital control bus line and a transmitter. The master AV center has at least a display device and a communication processor. A minimum of one slave device is provided, having a communication processor connected to the master AV center via the digital control bus line between the two communication processors. The transmitter transmits one command and/or data in a single packet from the master AV center to the slave device and vice versa through the digital control bus line.

An audio-visual system includes an AV center which may be connected to a plurality of image source components. An AV bus cable is connected respectively between each of the image source components and the AV center. The configuration of the interconnections between the AV center and all components of the system are identical and of simplified layout. Thus, complex interconnective methods and excessive numbers of cable, connectors, etc., are avoided while user convenience and general appearance of the system are greatly enhanced without compromising overall system functionality and/or operational capabilities.

A power control apparatus for an audio/video system includes an audio/video center having a main controller, a sub-controller, a memory, a display, and a selector for selecting a signal for display. A number of other audio/video units are connected to the audio/video center and are controlled by the main controller through the sub-controller, which passes commands and connection requests in both directions between the other audio/video units and the main controller. Upon a connection request from one of the other audio/video units fed to the main controller, the main controller determines whether the connection is the same as a previous connection and, if not, after a set time has elapsed the main controller through the sub-controller turns off the power to the previously connected audio/video unit.

Disclosed is a light-sensitive silver halide photographic material having at least one silver halide emulsion layer on a support, characterized in that at least one layer of the above silver halide emulsion layers contains a compound represented by the following formula (I): ##STR1## wherein n represents 0 or 1; A represents a compound residue which cleaves a bonding to Time in the case of n=1 or a compound residue which cleaves one of bondings to FL in the case of n=0; Time represents a timing group which cleaves a bonding to FL after cleavage from A; and FL represents a compound residue which emits fluorescence by cleavage of a bonding to Time in the case of n=1 and a compound residue which emits fluorescence by cleavage of one of bondings to A in the case of n=0.
摘要:
A photographic material having an excellent rapid processability, a high sensitivity and a less sensitivity variation due to a change of standing of the silver halide emulsion in the course of preparation of the light-sensitive material, and its preparation process are disclosed. The silver halide photographic light-sensitive material comprises a support bearing at least one silver halide emulsion layer thereon, and at least one silver halide emulsion layer contains highly chloride-containing silver halide grains having a silver chloride content of not less than 90 mol %, a water-soluble bromide of from 0.05 mol % to 2 mol % per mol of silver halide and a high boiling organic solvent having a dielectric constant of not higher than 6.0.

摘要:
A silver halide photographic light-sensitive material which is improved on fog without decreasing photosensitivity. The photographic material comprises a support and a photographic structural layer provided thereon containing at least one silver halide emulsion layer and at least one non-light-sensitive layer. A nitrogen-containing heterocyclic mercapto compound is contained at least two layers of the photographic structure layer, and at least one of these mercapto compound-containing layer is a non-light-sensitive layer.
摘要:
In the video tape recorder capable of providing a recording and reproduction with high picture quality, first and second heads of a first azimuth angle and for recording and reproducing the luminance signal is disposed on the rotary head cylinder. Third and fourth heads of a second azimuth angle different from the first azimuth angle, and for recording and reproducing the color signal is disposed adjacent to the first and second heads on the rotatry head cylinder, respectively. The second and fourth heads are disposed at a position separate, by a distance corresponding to the period of integer times one horizontal scanning period of the recorded video signal, from the position on the rotary head cylinder rotated 180.degree. from that of the first and third heads, respectively. A fifth head with the second azimuth angle is disposed at a positon rotated 180.degree. from that of the first head. High image quality recording and reproduction can be performed by using the first to fourth heads. The first and fifth heads reproduces the video information as recorded on the video tape in the format which is employed for the current home use VTR, and in which the frequency-modulated luminance signal and the low-frequency converted color sub-carrier signal are superposed and recorded in one track.
