Title: Display system for railway station guide display device
Inventor: KAWAI YOSHINORI
IPC: G09G5/24
Filed: 1990-05-23
Abstract: PURPOSE:To perform simple and low-cost display of a flow sentence having a content, such as a commercial, train delay information, by displaying a flow sentence, produced independently away from display information, at the lower stage of a guide display device by utilizing a non-using time in which train approach information is not displayed. CONSTITUTION:A display control device 1 stores a one-day railway schedule for trains starting from this station. Guide information displayed on a display device 2a at a No.1 platform and a display device 2b at a No.2 platform is produced by means of the railway schedule information and train passing spot information (A, B, and C) inputted from a relay interlocking device to control display of the display device. In this constitution, a sentence producing device 3 employing a personal computer having a word processor function is attached to the display control device 1. An edited flow sentence is inputted as sentence registration assignment to the display devices 2a and 2b to the display control device 1 from the key board of the sentence producing device 3. Meanwhile, the display control device displays assigned sentence data at the lower stages of the display devices 2a and 2b when no train approach information is displayed and sentence registration assignment is present.

This processed image is sent out through an image output device 6. In this case, the features of the behavior of the flame are found as the spatial presence possibility distribution image in a vague shape. Consequently, the combustion state can be analyzed at every specific temperature or flame band.

Abstract: PURPOSE:To form a transistor as a memory by a method wherein a memory gate is decided as the first conductor layer, a control gate as the second conductor layer, an impurity diffused layer is removed, and the control gate is so composed as to cover at least a part of the upper part of the memory gate, in an MNOS structure. CONSTITUTION:Write is performed by impressing a positive high voltage on the memory gate 7 and earthing an n type Si substrate 1, a p-well 2, and a Z region 5. Further, the p-well 2 immediately under the control gate 10a between an X region 3 and an SiO2 film 9 is inverted to n type at the earth level of the X region 3 by impressing a positive low voltage on the control gate 10a, and thereby a high electric field is applied between the memory gate 7 and the p-well 2. Then, electrons transfer from the p-well 2 in the direction of the memory gate 7 through the SiO2 film 9 by tunnel phenomenon, and then are trapped by the electron capture center in the neighborhood of the boundary surface between the SiO2 film 9 and an Si3N4 film 8, resulting in the finish of write. Write inhibition can be performed by supplying the X region 3 with a positive high voltage and earthing the control gate 10a.

Abstract: PURPOSE: To improve S/N by widening frequency deviation, by increasing an emphasis value, and by suppressing secondary distortion while operating a low-carrier FM signal passing part in a linear range by decreasing a FM modulation output at the time of photo recording regeneration by FM-modulating direcly a NTSC composite color signal by a low carrier.

In non-linear emphasis circuit 17, an input signal is emphasized at a high frequency by capacitor C 1  and R 1  and R 2  and its output appears at both terminal of R 2 . However, when a high-frequency signal level is extremely high, a signal passing through capacitor C 2  is clipped to a contact potential difference between diodes D 1  and D 2 . Both circuits 16 and 17 put emphasis of 10∼15dB on the color subcarrier. Circuit 17 puts sufficient emphasis on the high-frequency signal of a low level, so that S/N can be improved. Broad-band FM modulator 4 has much frequency deviation, improving S/N.
