摘要： PROBLEM TO BE SOLVED: To perform miniaturization by overlapping a light guiding display plate and a solar battery panel light receiving surface. SOLUTION: The display surface of the light guiding display plate 1 and the light receiving surface of a solar battery 3 are overlapped. The large part of sunlight made incident on the light guiding display plate 1 reaches a solar battery panel 3. Power generated by the solar battery panel 3 by receiving the reaching light is charged to a secondary battery 5 and the power is supplied from the secondary battery 5 to a lighting device 6 and a timer 7. Charging is smoothly performed from the solar battery panel 3 to the secondary battery 5 in the daytime. At night, the lighting device 6 is operated and a straight tube type fluorescent lamp 2 is lighted. The light emitted from the straight tube type fluorescent lamp 2 is made incident from the end face of the light guiding display plate 1 and reaches the other end while being multi-reflected inside the light guiding display plate 1, and during the time, the light exposed to a display part 4 printed on the back surface of the light guiding display plate 1 and formed by paint is diffused and reflected, emitted from the surface side of the light guiding display plate 1 to the outside of this display device and visualized.

摘要： PURPOSE:To obtain a window screen with superior man-machine interface by suppressing the omission of information in a master screen frame due to the superposition of a window screen frame in information equipment provided with a multi-window display function to a minimum. CONSTITUTION:The master screen frame 4 is divided into (n) unit areas of display area V of the window screen frame 6. An accumulated error SIGMA¦Xi-Xo¦ between each picture element gradation Xi17 and background gradation Xo18 for each unit area is calculated. Since the window screen frame 6 is superimposed and displayed on the minimum information area 20 that is the minimum area as a result of calculation, the omission of information in the master screen frame 4 can be mini-mized.

摘要： PURPOSE:To increase the transmission speed to be a multiple of 1.5 of a conventional speed by outputting a phase and an amplitude signal by two periods of a prescribed carrier frequency corresponding to a picture data so as to modulate a picture signal and using a half of the prescribed carrier frequency as a pass band width of a transmission reception picture filter thereby filtering the picture signal. CONSTITUTION:When a picture transmission command comes, a picture modulation section 22 modulates a picture signal by outputting a phase and an amplitude signal corresponding to each picture data for two periods of a prescribed carrier frequency. Then a transmission reception picture filters 23,25 taking a half of the prescribed carrier frequency as its pass band filter the picture signal. Thus, the transmission speed of the picture signal is increased by a multiple of 1.5 of a conventional speed and the sound quality almost equal to that of a conventional device is obtained.

摘要： PURPOSE:To shorten the transmission time per one picture by only transmitting line image data of an object to be displayed except a slave picture. CONSTITUTION:Equipment A on a line image data receiving side prepares control information 18a which indicates the displaying position and size of a window and can be received by transmitting-side equipment on the basis of window designating information 16a and transmits the information 18a before receiving line image data 12b. Equipment B on a line image data transmitting side transmits the line image data 12b related to a transmitting master picture which is a master picture from which the part corresponding to the slave picture 7a is removed on the basis of the control information 18a. The equipment A receives the data 12b related to the transmitting master picture and displays a window picture constituted of the transmitting master picture and slave picture. Therefore, the transmission time per picture can be shortened.

摘要： PURPOSE:To ensure the quality of voice when no transmission reception of a picture is implemented by assigning the line band to all voice transmission when picture transmission is not implemented. CONSTITUTION:When a transmission command of a picture comes, a transmission filter 6 having a split band characteristic is selected in response to the command signal 2 and when the transmission of the picture based on the picture transmission command is finished, a transmission filter 7 of the band characteristic of the line is selected. A reception filter 19 having a band characteristic split in response to the identification signal representing the arrival of a picture signal in the reception signal is selected at the time of receiving and when the reception of the picture signal is finished, the reception filter 20 having the line band characteristic is selected. Then the voice quality when the picture is not sent or received is improved.

摘要： PURPOSE:To shorten a signal transmission tine by executing amplitude modulation for two-divided picture data respectively with different phases by 90 deg., synthesizing signals and sending them together. CONSTITUTION:The picture element data to be successively sent are respectively distributed in a dividing circuit 20 and stored in respective line memories 211 and 210. The picture element data to be stored in the line memory 211 are delayed for one picture element part by a delay circuit 22 and synchronization is obtained. The stored picture element data are respectively inputted to phase amplitude modulating circuits 23I and 23Q and the signal of correspondent phase and amplitude is outputted. The phase and amplitude modulating circuit 23Q outputs a signal Q which is delayed by 90 deg. rather than a signal I of the phase and amplitude modulating circuit 23I. Amplitude synthesization is executed for those output signals in an amplitude synthesizing circuit 24 and the signals are outputted.
