Title: Image display device
Inventor: ONDA TETSURO
IPC: H04N7/08
Filed: 1987-09-29
Abstract: PURPOSE:To clamp a text signal TEXT at a fixed DC level and to prevent a horizontal mark or change of luminance at a weak electric field and the rolling of the horizontal mark in a vertical cycle at the time of interlacing from being generated by prohibiting the supply of a television signal TV to the processing circuit of the signal TV at the time of a TEXT mode. CONSTITUTION:In the TEXT mode, a horizontal blanking period TB and a horizontal blanking pulse HBLK go to 'H' levels, and a TV/TEXT switching pulse goes to the 'H' level, thereby, transistors Q1' and Q2 are turned ON, and potential at a point (a) drops gradually. When the potential drops to Vcc-VF (VF represents a voltage between the base and the emitter of a transistor Q3), the transistors Q3 and Q4 are turned ON, and the potential at a point (b) goes to the ground potential, and a transistor Q5 is turned OFF, therefore, the processing circuit of the television signal TV goes to a no input state. By setting such state, since the output voltage of a matrix 16 becomes the DC voltage, it follows that the text signal TEXT is clamped at the DC voltage, then, a stable clamping operation can be performed.

Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To allow a redundant operation and make a continuous operation available, even if self-distinguishing semiconductor elements of a VVVF (variable frequency) inverter equipment is short-circuited. SOLUTION: In the case that self-distinguishing semiconductor elements of a VVVF inverter equipment 3 is short-circuited the number of elements having short-circuit defects is detected and then is determined by an open control section 13 as to if the electric vehicle can continue to run by using the remaining good self-distinguishing semiconductor elements or if a main circuit needs to be opened. For example, in the case that all the self-distinguishing semiconductor elements connected in parallel have short defects, the VVVF inverter equipment cannot be driven, but in the case that one of the self- distinguishing semiconductor elements in each parallel combination is able to operate, the inverter is decided to be operable, and the operation is continued by driving an AC motor 5 which is a load.

Filed: 1988-09-30
Abstract: PURPOSE:To reduce an unused part of a continuous sheet from its end without reducing a sheet feeding accuracy at the time of printing by conveying the sheet by suitably switching a tractor mechanism of feeding type and a frictional mechanism. CONSTITUTION:When a continuous sheet 12 is printed while being conveyed by a push tractor 11 and its end 12a is separated from the tractor 11, a paper end switch 20 is turned OFF. When a CPU 31 inputs the OFF signal, a solenoid 24 is energized through a mechanical driver 37 to switch a sheet feeding mechanism from a tractor mechanism to a frictional mechanism. When the solenoid 24 is energized, frictional rollers 21, 22 are brought into contact with a platen 18 against the tension of a spring 23, and rotated upon reception of the rotary force of the platen 18. Thus, the sheet 12 is conveyed between the end of a printing head 17 and the platen 18. Thus, since the feeding mechanism is switched to the frictional mechanism, the sheet 12 can be continuously conveyed without reducing the sheet feeding accuracy.
