A screen transition diagram creator that creates a screen transition diagram illustrating complicated transition relations in an easy-to-understand manner, including: a screen transition diagram editor providing the screen transition diagram in which transition relations among plural screens are illustrated by plural screen nodes and arrows between the screen nodes; a screen transition pattern applying unit applying a predetermined screen transition pattern to a target screen node group that includes at least part of the screen nodes illustrated in the screen transition diagram to provide a pattern-applied screen node group; and a screen transition structure diagram creator creating a screen transition structure diagram by abridgement processing on the pattern-applied screen node group according to a display layout corresponding to the screen transition pattern. In the abridgement processing, arrows are deleted and an icon that simplistically illustrates a transition pattern between the screen nodes displayed in the display layout is added.

A monitoring control system includes a control device that performs a device control process, and a high-order system that monitors the device control process. The control device includes a control CPU that performs the device control process, and an information CPU that is connected to the control CPU via an internal bus. The control CPU includes a device memory that stores therein device data to be used for the device control process, the device data being related to the device. The information CPU includes a built-in database and a data collection unit. The data collection unit performs a data collection process of reading the device data from the device memory via the internal bus, and storing the read device data in the built-in database.

Monitoring control system and control device

An array antenna for use in, e.g., a radar includes a plurality of pairs of vertical polarization antenna elements and horizontal polarization antenna elements. A particular transmission/receipt module is connected to each pair of vertical and horizontal polarization antenna elements. A beam controller forms a transmission/receipt digital beam while a local signal generator controls a transmission/receipt frequency. The beam controller is connected to the transmission/receipt modules via a data bus and I/O (Input/Output) sections included in the modules.

In order to make possible the automatic setting of the sensitivity of a film to be used in an exposure controlling system by a simplified structure manufacturable at a low cost, the camera auto sensing system for ISO speed comprises: a pair of switches rendered to either a conductive state or a non-conductive state by judging a digital pattern indicative of the film sensitivities provided on a film cartridge mounted in a camera; a pair of electromagnets connected to respective switches; a film sensitivity changing lever coupled to the armatures of the respective electromagnets so as to be allowed to be moved to four positions in accordance with the operative state and the non-operative state of the respective electromagnets; and light amount changing means coupled to the film sensitivity changing lever to change the amount of light incident to an exposure-controlling light-receiving device in accordance with the movement of the changing lever. Thus, in this system, the sensitivity of the film to be used is sensed and set to the exposure-controlling system at each shutter release.

An X-class synchronization contact means for electric camera shutters has a switch which is closed by a shutter opening release stroke or by initial motion of a shutter opening operation. The switch is connected to a flash synchronization contact in order to prevent accidental ignition of a flashing means either in the initial step of a camera shutter release operation or in an exposure warning step accompanying the camera shutter release.

X-Class synchronization contact means for electric shutters

A flash synchronization controlling circuit for program type electric shutters. A first switching circuit is utilized for controlling the shutter closing and a second switching circuit is connected to the first switching circuit and utilized for controlling the flash actuation in order that the flash synchronization controlling circuit may be simplified and to provide a very positive and stable flash synchronizing operation. The flash synchronization controlling circuit is arranged so that the switching operation of the second switching circuit can be effected earlier by a predetermined time interval than that of the first switching circuit.

Flash synchronization controlling means for program type electric

An electric shutter of a program type provided with a single actuating spring connected at one end with a shutter blade opening and closing lever and at the other end with a closing actuating member. One end of the actuating spring acts to open the shutter blades through the opening and closing lever and the other end acts to close the shutter blades through the closing actuating member and opening and closing lever so that the structure may be simplified and the shutter releasing operation may be made with a light force. A spring acting to press an armature lever against an electromagnet is so arranged as to lose its action when the closing actuating member is in an uncocked position. Further, this electric shutter is provided with a synchroswitch so arranged as to be closed after the lapse of a predetermined time after the shutter is released irrespective of the diaphragm aperture to be set so that a flash-photographing may be positively made.

Electric shutter

An auto-strobe flash means for cameras which comprises a variable resistor inserted in a light measuring circuit of an electronic exposure time controlling arrangement for a shutter, the resistance value being a function of the photographing distance. A main flash discharge tube is ignited when the shutter is fully opened, and a differential amplifier is provided for controlling the shutter closing time in response to the value of the variable resistor.

Auto-strobe means for cameras

An automatic flash-photographing arrangement whereby flash-photography is automatically carried out at a preset shutter speed when brightness of an object is lower than a pre-determined value, the arrangement comprising an automatic exposure control circuit, an electronic change-over switch means connected to said automatic exposure control circuit, and a flash illuminating circuit connected to said change-over switch means. The electronic change-over switch means comprises an adjustable RC delay circuit which can be set for the purpose of determining whether or not flash-photography has to be carried out.

Automatic flash-photographing arrangement

An electric shutter comprising a diaphragm-aperture controlling cam plate which is started by shutter release operation, an electro-magnet capable of stopping the movement of said cam plate, and an RC delay circuit capable of controlling the energizing time of said electromagnet, in order (1) that the diaphragm aperture can be automatically set according to brightness of the object to be photographed and (2) that exposure can be carried out at a proper shutter speed taking the setting of the diaphragm aperture into consideration.
