Title: Flat plate type picture display device
Inventor: TOMII KAORU
IPC: H04N5/68
Filed: 1988-11-29
Abstract: PURPOSE:To improve the picture quality by applying a signal waveform formed by deviating a voltage sequentially lower than the voltage applied to an electrode opposite to a vertical scanning electrode to each of vertical scanning electrodes subject to split for a prescribed period. CONSTITUTION:A voltage VD-VCC is applied to a vertical scanning electrode 301-A for one horizontal scanning period (1H) after start of vertical scanning and a voltage VD is applied to other vertical scanning electrodes 301-B - 301-Z. The same or higher voltage VD is applied to the vertical scanning electrode 301-A after a time required for vertical scanning of a distance twice a value depending on the distance (d) between the vertical scanning electrode 301 and a fluorescent screen 302 and depending on the drive condition again. The level of the vertical scanning electrode 301-B is changed from the VD to (VD-VCC) after the elapse of 1H and the voltage is changed into the VD after application of aH. Similarly, the voltage (VD-VCC) lower than that on the fluorescent screen continues for aH period and the voltage whose phase is deviated by 1H each is applied to each vertical scanning electrode 301 to apply vertical scanning operation. Thus, the picture deterioration of a picture is prevented.

Title: Timer circuit
Inventor: TOSAKA TAKAO
IPC: H03K17/28
Filed: 1988-11-28
Abstract: PURPOSE:To obtain a timer circuit able to be transited in the standby state regardless of the final state of an input signal by placing a circuit in pre-stage generating a logic differentiating signal of a front ridge of the input signal to an input circuit at front end. CONSTITUTION:A D input of a D-FF 18 goes to 'H' via an inverter 17 when a switch 1 is turned on. Since an output of the inverse of Q goes to 'H' and an output node of a NAND gate 19 changes to 'L'. In this case, a FF 8 is turned on via a buffer 22 and a pnp transistor(TR) 4, an output node B goes to 'H' and a timer is activated. A clock from an oscillation circuit 11 started after an output of the NAND gate 19 changes to 'L' is given to an input T of the D-FF 18, the level of the output of the inverse of Q changes to 'L' and an output node C of the NAND gate 19 changes to 'H'. Thus, the output state of the NAND gate 19 is unchanged regardless of the state after the switch 1 is turned on and the state is transited to the standby state regardless of the input state after the end of timer operation.

Abstract: PURPOSE:To enable facsimile equipment to execute a retransmission request by itself so as to improve the workability by sending a telegraphic message explaining that a recording output is failed to a transmitting side. CONSTITUTION:When abnormality occurs in one of a memory section 6, picture processing section 7, and plotter 5, a system control section 2 recognizes that the recording output of picture data by means of the plotter 5 is not properly performed and prepares a telegraphic message explaining that the recording output is failed.

The section originates a call to the opposite facsimile equipment and transmits the message. Therefore, the transmitting-side operator makes a necessary process for retransmitting the transmitted original on the basis of the message.
