Title: Television receiver
Inventor: TAKAHASHI TAKASHI
IPC: H04N5/44
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To remove a harmful picture on a real time basis or with a delay of about several seconds and to prevent missing of sound by taking a difference between pictures of recorded frames and displaying an immediately preceding frame instead of displaying a picture if a picture with a substantial change exists. SOLUTION: An inputted video signal is digitized by a picture digitalization device 1, and the digitized video is stored in a picture recording device 2 for about 100 frames. At the same time, a sound signal is digitized in a sound digitalization device 11 and is recorded in a sound recording device 12. Recorded pictures are compared in a picture difference comparison device 4 in a frame unit. When the difference is larger than a predetermined value, the picture is judged to be a subliminal or flicker picture. The picture of the frame judged as a subliminal picture is substituted for an immediately preceding. The video outputted from a picture averaging device 3 is synchronized with a sound reproduction device 13 in a picture reproduction device 5. Thus, a gap does not exist in the output picture.

Title: Stroboscope controller
Inventor: OTAKA YUKIO
IPC: G03B15/05
Filed: 1988-04-15
Abstract: PURPOSE:To prevent the voltage of a power supply battery from suddenly dropping by keeping the temperature rising of the power supply battery caused by a continuous stroboscope photographing under a prescribed temperature before reaching the actuating point of a temperature sensing resistant element incorporated in the power supply battery. CONSTITUTION:When the temperature of a battery 1 reaches to the prescribed temperature by means of the continuous stroboscope photographing, the output of a comparator 22 inverts to a low level; therefore, the output of an AND gate 28 is fixed to the low level. Thus, even if the signal for starting charge is inputted thorough a terminal B, the signal is not received, and a transmitting transistor 32 is still turned off during this time. Consequently, it will not happen that the continuous using of a stroboscope device makes the temperature of the battery 1 be risen more and the temperature sensing resistant element 1a incorporated in the battery be actuated. Thereafter, the temperature of the battery 1 drops to be lower than the prescribed temperature, a DC/DC converter circuit starts an action; and the charge to a main capacitor 14 is finished, so that the action is stopped.

Abstract: PURPOSE:To realize a simultaneous transmission of the two independent signals of the same frequency, by installing the transmitter/receiver between the intermediate tap and the secondary side  of the high frequency transformer connected to the parallel 3-wire type inductive line and providing two sets of the transmitter/receiver to the travelling object. CONSTITUTION:High frequency transformer 10 is connected to parallel 3-wire type inductive  lines 1-3 which are laid along the path of the travelling object. Then fixed transmitter/receiver 9  is installed at the secondary side of transformer 10 along with fixed transmitter/receiver 4 provided between the intermediate tap and inductive line 2. The travelling object incorporates bar-type magnetic core antenna 5 which is set vertically to each inductive line with the center set onto line  2, transmitter/receiver 6, loop antenna 7 which is parallel to the surface of the inductive line with the longer side crossing vertically the position right above line 2, and transmitter/receiver 8 each.  The current supplied from transmitter/receiver 4 is not coupled to transmitter/receiver 9 and antenna 7 but coupled to antenna 5. Thus the transmission is possible to transmitter/receiver 6.  On the other hand, the current from transmitter/receiver 9 is not coupled to transmitter/receiver 4  and antenna 5 but coupled to antenna 7 to secure the signal transmission to transmitter/receiver 8.  And no mutual coupling is given between the currents of antennas 5 and 7, thus causing no interference even with the same frequency.
