Abstract: In order to reduce the storage capacity required for storing system configuratuion information in an AV system composed of a plurality of AV component devices, a ROM 5A stores a plurality of predetermined systems configurations of the AV component devices. An SIP (system information pointer) memory 6 temporarily stores an SIP which indicates any of the system configurations stored in the ROM 5A. The SIP is finally stored in a nonvolatile memory which retains stored data after removal of electric power.

Abstract: In order that an electronic device such as an audio or video device may be inspected and the state thereof may be set without making operation of the electronic device unstable when a rear cover is attached to the electronic device, an inspection jig (4) is connected through a D2B bus (2) serving as an external AV bus to electronic devices (TV1), (TV2) and (TV3). The state of the electronic device is checked by supplying a request signal to the electronic device (TV1), (TV2) or (TV3) through the D2B bus.

Abstract: In an AV (audio and video) system, it is possible to suppress such a feeling of a user that he has to wait for an actual operation of an AV appliance after an operation instruction has been inputted until the AV appliance is actually operated. Upon receipt of a recording operation instruction of a VTR 3 issued from a remote controller 2, a CPU 12 first turns ON a power supply of the VTR 3. Thereafter, such a message indicating that the inputted instruction corresponds to the recording operation of the VTR 3 is displayed on a CRT 17. When a user inputs an instruction for confirming this message via a remote controller 2, the CPU 12 instructs the VTR 3 to start its recording operation.

Abstract: A highly corrosion-resistant, paint-adherent, and lubricating polymer-containing coating on a metal surface can be formed by contact with an aqueous solution (pH=2.0 to 6.5) that contains an acidic compound and polymer with the following formula (I): ##STR1## in which the X bonded to the phenyl ring in formula (I) represents a hydrogen atom, a hydroxyl group, a C.sub.1 to C.sub.5 alkyl group, a C.sub.1 to C.sub.5 hydroxyalkyl group, a C.sub.6 to C.sub.12 aryl group, a benzil group, a benzal group, an unsaturated hydrocarbon moiety condensed to the phenyl ring so as to form a naphthalene ring, or a group corresponding to formula (II): ##STR2## in which R.sup.1 and R.sup.2 in formula (II) each independently represent a hydrogen atom, a hydroxyl group, a C.sub.1 to C.sub.10 alkyl group, or a C.sub.1 to C.sub.10 hydroxyalkyl group; the Y.sup.1 and Y.sup.

Abstract: A power control system which causes a first slave apparatus to be disconnected from a master apparatus and a second slave apparatus to be connected to the master apparatus, by command from a user; and causes the power to be turned off to the first apparatus after disconnection--but does not disconnect the first apparatus before verifying that it is in fact already connected to the master apparatus.

Abstract: A method of controlling signal lines among a number of audio/video units in a system where a central unit including a selector and the other audio/video units are mutually connected via a single control bus and also via audio/video signal cables includes the steps of enabling the central unit to manage identification numbers of the audio/video units on the control bus and also connection data among the audio/video units, classifying the audio/video units in accordance with the respective categories, connecting the signal line between one of the audio/video units and another one of the units, enabling one audio/video unit to designate by category the other audio/video unit to be connected and, after such designation, enabling the central unit to select the specific audio/video unit that satisfies the requirement, out of all of the audio/video units of the designated category, and then switching the selector of the central unit thereby connecting the desired signal line between the relevant audio/video units.

Abstract: When trying to make a correct connection, a VCR 13, which should be connected to terminal 15, is connected instead to terminal 16 by mistake, so that a signal generator 13a constructed internally within the VCR 13 outputs a test signal, but the switcher 8 selects the signal being input at terminal 15 (where there is no signal present), and provides it to detector 12, but as there is no signal at terminal 15, the CPU 5 determines that the connection is incorrect and displays a user prompt to this effect on the CRT 10.

Abstract: A power controlling apparatus turns off a power to an apparatus whose connection to a central apparatus has been cut by a connection change, thus selectively turning off a power to an apparatus not required by the central apparatus. A locking/unlocking apparatus determines a value of the locking timer in the interrupt timer routine and, when the value has exceeded a predetermined level, takes a slave apparatus out of the locked state, thereby simplifying programming.

Abstract: A step manufacturing method of a silver halide photographic emulsion comprising silver halide grains having a silver chloride content of not less than 95 mol % is disclosed, the method comprising the steps of mixing a silver salt and a halide to form a silver halide emulsion and chemically ripening the resulting silver halide emulsion,wherein a compound having two or more sulfonic acid or sulfonic acid salt groups in its molecule is added to the silver halide emulsion at the chemical ripening.

Abstract: There is disclosed a communication system using a bi-directional bus, which includes a plurality of devices (e.g., TV image receiver or video tape recorder, etc.) connected to each other. Each device includes a transmit signal formation unit having a frame structure including an address field for specifying addresses of devices between which communication is carried out, a control field for specifying whether communication is carried out in the state where device on the receiving side is locked or in the state where that device is unlocked, and a data field for specifying data to be transmitted. For transmitting data having a data quantity greater than data capacity of the data field, the data is divided into a plurality of frames, an indication to lock device on the receiving side is given to control field of a frame transmitted first, and an indication to unlock that device is given to control field of a frame transmitted last.

Abstract: Connection patterns as many as possible can be managed by less standard patterns. Connected states of a VTR (30), a VTR (40), a VTR (50), a VTR (60), an MDP (70), a tuner (80) and an AV center (100) composing a standard pattern are memorized in advance. A flag (N) representing the non-use is set to an AV equipment (e.g., VTR (60)) that is not used in actual practice of the AV equipments constructing the standard pattern. Therefore, a system in which a part of the AV equipments constructing the standard pattern is omitted can be managed similarly to the system of the standard pattern.

Abstract: A power controlling apparatus turns off a power to an apparatus whose connection to a central apparatus has been cut by a connection change, thus selectively turning off a power to an apparatus not required by the central apparatus. A locking/unlocking apparatus determines a value of the locking timer in the interrupt timer routine and, when the value has exceeded a predetermined level, takes a slave apparatus out of the locked state, thereby simplifying programming.

Abstract: A bath for treating metal surfaces for the formation thereon of composite films for the cold working of metal advantageously comprises an otherwise conventional conversion coating bath that also contains organic cationic polymer having at least 1 cationic nitrogen atom per molecule and having a molecular weight of 1,000 to 1,000,000, or a salt of such a polymer. Major improvements in the lubrication properties, particularly in the seizure resistance, can be achieved by applying out a conventional lubrication treatment on such a composite film. Specifically, practical operating limits in metal cold working, e.g., the working degree or ratio, working speed, tool life, and the like, can be increased in a single step. This is useful in terms of improving productivity, product stability, cost reduction, and the like.

Abstract: A communication protocol can communicate data among apparatus by a simple procedure efficiently. In an AV center (1) (D2B control unit (1a), for example, a communication mode thereof is set in the master transmission mode, and a packet of one frame is transmitted to a TV (2). In the TV 2 (D2B control unit (2a)), its communication mode is set in the slave reception mode. When a packet of one frame from the AV center (1) is received by the TV (2), a communication between the AV center (1) and the TV (2) is ended.
