摘要： PROBLEM TO BE SOLVED: To prevent warp and twist, which occur in a back plane at the time of mounting printed circuit boards on a shelf, and to mount them with high density without invading into the mounting space of the printed circuit board in the shelf in a printed circuit board mounting structure. SOLUTION: A plural printed circuit boards 80 are mounted on the shelf in parallel at the same pitch. At that time, plugs 82 mounted on the printed circuit boards 80 are engaged and connected with connectors 52. Reinforcing members are installed in the clearances of the plural printed circuit boards 80 which are mounted in parallel and in areas which does not interfere with the insertion/extraction of the printed circuit boards 80. The reinforcing members are long flat boards having rectangular sections. The arbitrary installation number of the reinforcing members are fixed and installed in arbitrary positions in accordance with the number of the mounted printed circuit boards and with insertion force and extraction force.

摘要： PURPOSE:To attain communications between terminals by providing a terminal capable of expanding a header picture display part area according to information data transmitted to other terminals, and a videotex communication processor which provisionally accumulates information data transmitted from terminals to other terminals and controls a bus connecting terminals. CONSTITUTION:In the terminal 9, information data is inputted, and a telephone set 6 calls the terminal 9' and places a call to the videotex communication processor 2, thereby transmitting the information data. At that time, the header picture display part area expansion means 5 expands the display area of a header according to the size of the information data. The videotex communication processor 2 analyzes the information data by an exchange information processor 13 and transmits the information data to the terminal 9' being a destination through its bus. The terminal 9' displays said data on a reception information display part 11'. Thus retrieval from information terminals in a center and inter-terminal communication can be realized.

摘要： PURPOSE:To collectively manage operating states of telephone circuits by providing a function which sets the actuation and confirmation requiring information of plural pseudo terminal generators from a key telephone set, etc., through a public telephone circuit and periodically switching the output information of plural terminals to be confirmed. CONSTITUTION:To test each circuit of equipment 5 to be tested, plural pseudo terminal generators 4 are actuated from the key telephone set 1 through an exchange 3. In addition, information required for the tests is inputted from the telephone set 1 to urge the start of the tests. By starting the tests, the output information from each circuit is successively monitored by means of a videotex terminal 2 and the operating state of each circuit is confirmed. Therefore, the pseudo generating operations of the plural terminals can be controlled and the operating states of the circuits can be confirmed by monitoring the information of each circuit from a remote place. Thus, the states of the lines can be managed collectively.

CONSTITUTION:When a melody menu 7 is sent from an information center 5 to a VIDEOTEX terminal A 3, and is displayed, a user key-inputs melody selection information 6 he desires to add. In the information center 1, the corresponding melody information from the melody menu 7 and the mail information 5 are synthesized by the melody adder 8 on the basis of the melody selection information 6, and it is stored as melody addition information 9. The user of the VIDEOTEX terminal provided with mail service can obtain melody added mail information by retrieving the stored melody addition information. Thus, the melody added mail information can be obtained easily.

摘要： PURPOSE:To cope with the information of an emergency news by providing an information center having an emergency picture input device, an emergency picture output device, an emergency picture accumulation device and an emergency information processor for transmitting the emergency information and a video tex terminal having function for receiving the emergency information and displaying the existence of the emergency news. CONSTITUTION:When there is the emergency news, the emergency picture is formed in the information center, and informs the existence of the emergency news to the video tex terminal 1 having an emergency status display function. This information is carried out by transmitting the emergency information (in this case, limited to a terminal transmitting a terminal profile). When the video tex terminal having the emergency status display function receives the emergency information, it informs the existence of the emergency news to a transmitter by a sound or flashing or lighting of a light. If required, by using a function for transmitting an emergency picture retrieving number to a video tex communication processor 5, the picture is retrieved. At that time, the previous picture is stored in the information center 6, and after the display of the emergency picture is completed (when pressing a setback button), it is displayed again.

摘要： PURPOSE:To enable a mounting structure light and excellent in strength to be enhanced in wiring board mounting density by a method wherein wiring boards are housed in a unit frame composed of the guide frames of a honeycomb-shaped structure composed of the assembled hexagonal pillars of the same shape. CONSTITUTION:A large number of hexagonal pillars of the same shape are assembled into a honeycomb-shaped structure, and a thin plate is used as the side wall of the structure concerned. A unit frame 3 is mounted on a guide frame 1 surrounding the structure concerned, and the lateral and the vertical sides of them are jointed together by rivets 9 or the like, whereby the frame 3 and the guide frame 1 are formed into one piece. A large number of guide rails can be automatically constituted taking advantage of the diagonals of the hexagonal pillars, so that wiring boards 2 can be housed high in mounting density in this honeycomb structure. The rear of the guide frame 1 is joined to an intermediate plate 8 provided with a connecting groove 11, and a unit cover 4 is fitted to the front of the guide frame 1, whereby the guide frame 1 longitudinally sandwiched between the plates 8 and 4 is made to serve as a honeycomb plate, so that a mounting structure of this design can be lightweight and enhanced in mechanical strength.

摘要： PURPOSE:To easily recognize the retrieval time of information at the time of retrieving by editing the information representing the activity time of a video tex in a form of interruption message when a request to display an activity time is issued from a video tex terminal, and displaying it on a header part. CONSTITUTION:When a transmitter selects the timer value of a menu and inputs it from a key pad 9, an information center 6 sends a time display interruption message 7, for example, at a cycle of 10seconds. The video tex terminal 1 displays the timer value on the header part for display. For example, after 10seconds, the information center 6 sends a time display interruption message 7' on which the timer value of 10seconds is added, and it is displayed on the video tex terminal 1. During that time, another retrieval can be performed. In such a way, since a user can recognize the retrieval time on the spot, a standard for charge at the time of performing long time retrieval can be obtained. Thus, since the user of the video text can perform the retrieval of the information as referring to the retrieval time of the information, it is possible to set the standard for the charge and to improve serviceability.

摘要： PURPOSE:To explain an image on a user terminal by using a voice by downloading voice data and storing in the storage device of the user terminal prior to the downloading of image data, and downloading telesoftware for outputting the voice data to the user terminal together with the image data. CONSTITUTION:The user terminal(GT) 2 has a function for switching the voice data and picture data between a display device(CRT) 4 and the storage device(DK) 3 and a function for outputting the voice data from the storage device(DK) 3 to a voice output device(SP) 5. Then the voice data is downloaded on the storage devices DK3 of all user terminals GT2 before the image data is sent out to the user terminal GT2 from an information center, and then the telesoftware for starting the output of the voice data is downloaded together with the image data. Consequently, the voice explaining the image and the image are outputted simultaneously to improve the service to users.
