摘要： PURPOSE:To reduce the redundancy of information to be exchanged by allocating different identifies (IDs) to the same object to be controlled and storing an ID string to be abbreviated in a memory to form network control information. CONSTITUTION:A control agent for transmitting control information is found out at first, and then plural objects to be controlled are constituted as hierarchical tree structure based upon prescribed master-slave relation. Respectively different IDs are allocated to respective controlled objects, an abbreviated object corresponding to the control agent is specified and stored in an internal memory. Then, network control information is formed by using the abbreviated IDs to which abbreviated IDs are added. The control information can be specified as a control object instance by using the ID included in the control information and the ID stored in the memory and transmitted to the control agent. Since the expression of the ID is shortened, the quantity of transferred information between a control manager and the control agent can be reduced and the performance of control operation transmitting processing and analytical processing for reception can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a power supply system capable of consistently and efficiently supplying the power to a load device having an instantaneous load fluctuation and an intermittent no-load state while being free from any effect of the voltage drop caused by the instantaneous load fluctuation.
SOLUTION: Fluctuating loads 60, 61 having instantaneous fluctuation and intermittent no-load state are included in a plurality of loads 9, 60, 61. A bus bar comprises an AC bus bar 5 for supplying the AC power generated by a part of generators 22, 23 to an inverter 7, and another bus bar 44 for supplying the AC power generated by other generators 20, 21 to the fluctuating loads 60, 61; and further comprises switches 2, 3 for connecting the outputs of the generators 20, 21 connected to the other bus bar to the AC bus bar 5. When the instantaneous fluctuation of the fluctuating loads 60, 61 is continuously repeated, the switches 2, 3 are in an open state. When the fluctuating loads are continuously in a non-load state, the switches 2, 3 are in a short-circuit state.

摘要： PURPOSE:To execute communication between resources under the control of different host computers by informing the change part (differential information) of the resource in a self-domain of the inside of the host computer to control the resource in each domain. CONSTITUTION:When the resources in respective domains 1-3 are changed, the change is registered to a control table 13 in host computers 4-6 of the domains 1-3 and next, the change part (differential) information are transmitted to each control table 13. The respective host computers 4-6 execute change operation processing required for the communication with the changed resource by using the information. The control table 13 monitors to which host computers 4-6 the differential information are given and to which degree the change operation processing is advanced concerning contents in the opponent host computer. Then, the history of the processing is registered as well. Thus, when the host computer under stopping is started, the differential information to be transmitted to the host computer can be known and the changed resource in the different domain can be accessed even from the domain of the host computer to be started in the middle of operation.

摘要： PROBLEM TO BE SOLVED: To prevent a backlight from leaking at a liquid crystal sealing hole part, and to make it possible to obtain excellent display quality, by arranging a black matrix in the liquid crystal sealing hole part. SOLUTION: A black matrix BM consisting of an organic resin such as aclylic, epoxy, polymido resin, added with carbon black, black organic pigment, etc., is formed in a prescribed pattern on a transparent glass substrate SUB2, and color filters FIL (R), (G), (B) are formed respectively in prescribed patterns on it. The peripheral part of a pixel part is formed into a frame shape with a proper width and the pattern light shielding the liquid crystal sealing hole INJ part for preventing a light leakage from the backlight when a liquid crystal display element is assembled in a module. In such a manner, since the BM is arranged on the liquid crystal sealing hole INJ part, the light from the backlight is interrupted in the INJ part, and the light leakage from the liquid crystal sealing hole INJ part is prevented, and the display quality is improved.

摘要： PURPOSE: To enable electric connection without dropping insulation capacity of an insulating cover by providing a metallic plate which has a catch for catching a metallic shield layer with elastic force in contact and a connector for electrically connecting other conductor. CONSTITUTION: This shield cable terminal connecting device is equipped with a connector 7a, which becomes a mounting terminal at the time of soldering an external cable 5, consisting of a brass plate, a catch 7B, which catches a shield cable 3, and others. And, the wires 3 of two shield cables are electrically connected with each other by peeling off the outside cover 4 and exposing the shield cable 3 and catching its section with the part 7B. Next, the heat during soldering is dispersed by connecting the external cable 5 to the shield cable terminal connecting device 7 by solder 7, and the head can be prevented from being conducted directly to the insulating cover 2. Furthermore, the number of used cables 5 and devices 7 can be reduced by binding a plurality of shield cables en block, so the connection work can be simplified.

摘要： PURPOSE:To achieve a vibration test where frequency is changed arbitrarily in a wide frequency range by placing it within a DC magnetic field and allowing AC current to flow through it for causing an inner wiring to be vibrated. CONSTITUTION:Output of an AC power supply 13 is amplified and adjusted based on confirmation of an ammeter 15 for enabling an arbitrary AC current to flow through a fuse 12. Then, this fuse 12 is placed within DC magnetic field due to a magnet 17, thus enabling an inner wiring 12a of the fuse 12 to be vibrated by electromagnetic force. By changing magnetic flux density or current of a magnetic field for the inner wiring 12a, an arbitrary acceleration can be applied to. In this case, there is basically no limitation in frequency, thus enabling vibration of a wide range of frequency to be applied to.
