Title: Video processing circuit
Inventor: ASAI TOSHIYA
IPC: H04N5/926
Filed: 1991-04-09
Abstract: PURPOSE:To prevent the position of an auxiliary code inserted into a video signal from being changed even when an output phase is varied. CONSTITUTION:A control circuit 30 controlling an output phase of a video signal is provided with a variable phase shift circuit 34 to shift the phase by a prescribed amount, and a fixed phase shift circuit 40 shifting the phase by a prescribed amount. A switching means 38 selects a video signal (c) or (d). The video signal (d) is selected only for a prescribed period including at least an auxiliary data and in other case, the video signal (c) is selected. Since the auxiliary data is always extracted from the video signal (d) shifted by a prescribed amount, the inserted position of the auxiliary data is unchanged regardless of the output amt. of phase. Thus, the extraction of the auxiliary data is ensured.

Abstract: PURPOSE: To make effective use of a plurality of fire robots by using a control panel, in the event of a fire, for specifying the fire robot which is to extinguish the fire, and then issuing a command for movement so that the fire robot is moved to near the fire source. CONSTITUTION: When a fire receiver 44 receives fire information (fire signal) from a fire detector 45, a fire source is determined based on the fire signal, and position information is outputted to a control panel 41.

Title: Inverter
Inventor: KIUCHI MITSUSACHI
IPC: H02M7/48
Filed: 1978-06-23
Abstract: PURPOSE:To produce substantially constant high frequency output of an induction heating cooking oven even if the material of a pot is altered by controlling the conduction pulse of a switching element in response to the output obtained upon detection of the voltage of the switching element. CONSTITUTION:When a switching element 32 is turned off, the voltage of the voltage suppressing terminal C of the element 32 becomes sine waveform upon flowing of resonant current iC via a heating coil 31 and a resonant capacitor 34. When the voltage VCE alters from positive to negative, a diode 33 is conducted to flow a current iD to thereby flow a current determined by the impedance of the coil 31 through the element 32 before the current iD become zero. The current iF flowing through the element 32 is varied according to the material of a pot at the peak value of the current iF flowing through the element 32. When the peak suppressing voltage of the element 32 is set constant, the peak current also becomes constant to thereby produce constant induction heating output.

At this time, if the interleave mode or flying mode is selected as a transfer mode, the length of the document is detected by a document length detector 27 for setting the number NM of document to be stacked on a intermediate tray 41. The document which was read out, if it is required to be supplied again so that the back may be read because it is a duplex document one, is stacked on the intermediate tray 41 by operating a junction claw 51 in the direction indicated by the arrow (a), and if it is single face document or duplex one whose back was read out, it is stacked on a discharged paper tray 53 by switching the junction claw to the direction indicated by the arrow (b). Thus, total printing time can be reduced compared with the case in the through mode.
