Abstract: A system construction assistance apparatus includes a first display screen, a second display screen, and a processing section displaying units each belonging to one of categories on the first display screen such that the units are sorted by category, receiving a first input to select one unit from the units displayed on the first display screen, generating a system configuration diagram on the basis of the received first input, and displaying the generated system configuration diagram on the second display screen. After a first input is newly received and before a next first input is received, the processing section predicts a category to which a unit to be selected by the next first input belongs on the basis of first inputs received in a past and presents the predicted category as a candidate category to a user.

Abstract: A control system management apparatus, includes: a system configuration editor unit including a display unit on which a user designs a network configuration of a control system including networks, at least one relay station, and at least one device to be controlled; an information collection unit collecting, from the relay station, network setting information and routing information; and a network configuration analysis unit analyzing a network configuration of the control system based on the network setting information and the routing information acquired through the information collection unit from a connection station that is any relay station and serves as a starting point, wherein on the basis of the result of the analysis, whether the connection station can communicate with the relay station and the device to be controlled at that point in time is displayed in a network configuration diagram on the display unit.

Abstract: A unit property for defining the manufacturing industry software unit is described with the use of the action of an access to a domain concept data model element of an activity that is realized by the software unit described in an implementation specification format. As a result, the manufacturing industry software unit can be formally described as the property that defines the action of the description when it is described by using the software unit profiling template described in the implementation specification format defined by ISO 16100-2. Also, a request in conducting retrieval can be described in the same format as the above, and the process semantics of the existing manufacturing industry software unit can be efficiently registered in the directly expressed and in a common form, and effectively retrieved.

Abstract: A delay time period, such as the H/W process time period, and the S/W process time period needed for starting up a timer, and a time period from the task starting to the packet transmission beginning are predicted and stored in the control information in advance. A set value calculating part calculates a timer set value at the system initialization. In a packet forming part, the timer set value is set in a relative time timer for starting the timer. The relative time timer generates an interrupt after a specific elapse time has passed for starting a transmission requesting part. By dint of this, the time lag of the time period from the period interrupt to the packet transmission beginning can be reduced, and each of the formed packets is certainly requested to be transmitted within each requested time period for processing.

Abstract: An object of the present invention is to provide a CRT for improving brightness without changing a conventional electron gun, a light emitting layer, etc.A color cathode ray tube according to the present invention is characterized in that both or one of a panel glass 3 and a safety glass 1 used on a front face of the color cathode ray tube uses glass having characteristics in which spectroscopic transmittance to an electromagnetic wave near 580 to 700 nm in wavelength is relatively higher than spectroscopic transmittances to electromagnetic waves near 430 nm and 530 nm in wavelength.

Abstract: A cordless telephone system includes a subscriber line interface wired to a subscriber line, and cordless terminal connected to the subscriber line interface via a radio communication. The subscriber interface includes only interface conversion means for performing conversion between a wired signal of the subscriber line and a radio signal of the cordless terminal and means for call connection. In the cordless terminal, it is only required to provide the radio interface circuit which can communicate with the radio interface portion of the subscriber line interface, and a telephone function circuit for enabling connection with the subscriber network. Therefore, the telephone system can be established with employing an arbitrary terminal.

Abstract: A method and apparatus for correcting the tracking of an electron beam which includes the steps of generating a supplemental magnetic field, generating a reverse magnetic field and removing the correcting magnetic field. The direction of the supplemental magnetic field is substantially the same as the direction of a terrestrial magnetism. The reverse magnetic field substantially offsets the terrestrial magnetism.

Abstract: A heat exchanger, intended for use in hot water heaters, in which a tank and a hot water inlet pipe are formed integrally with each other, at a junction of which is placed a valve for control of the flow rate of hot water. The valve has a valve body disposed in close contact with a valve seat for rotation about its own axis relative thereto. Secured to the valve body is a rotary shaft which can be operated from outside. The valve body and the valve seat have respective through holes formed therein which can register with each other with their registered area variable to vary the flow rate of hot water with a change in the registered area of these through holes. The valve body is adapted to be placed in tight contact with the valve seat substantially solely by the pressure of hot water in the inlet pipe.
