Title: Automatic gain control circuit
Inventor: OKAWA SHINJI
IPC: H04N5/52
Filed: 1984-07-18
Abstract: PURPOSE:To decrease the reduction at a video signal peak output level when an input signal level ratio islarge by controlling the feedback amount of a feedback circuit of the 1st automatic gain control circuit of a television transmitter with a peak voltage (current) of a frequency component being a difference between a video carrier and audio carrier. CONSTITUTION:A part of an output of the 2nd automatic gain control circuit 17 is branched, subject to square detection by a square detector 18, the difference frequency component between the video carrier and the sound carrier is extracted by a band pass filter 19, peak value detection is applied by the peak value detector 20 and its voltage controls the 2nd automatic gain control circuit 17. That is, since the control is given so that the output of the 2nd automatic gain control circuit is smaller as the difference of the both is larger until the video peak level and the sound peak level are equal, no suppression of the video carrier takes place. Thus, even when the input signal level ratio such as television broadcast equipment is large, until the sound carrier level does not exceed the video carrier level, the reduction at the video signal peak output level is decreased.

Title: Paper sheet conveyor device
Inventor: NATORI TOSHIYUKI
IPC: B65H33/04
Filed: 1990-06-07
Abstract: PURPOSE:To allow plural groups of left-behind paper sheets to be stored into a storage part by placing a separating medium for separating the takeout forgotten paper sheets from the succeeding takeout forgotten paper sheets, on top of the takeout forgotten paper sheets at the time of these paper sheets being stored in the storage part. CONSTITUTION:When time-out is detected without paper sheets being taken out of the takeout port of a paper sheet conveyor device, a control part regards these paper sheets as left-behind sheets 5 and stores them into a paper sheet storage safe 2 through a carrier path. After storing the left-behind paper sheets 5 into the paper sheet storage safe 2, the control part delivers one sheet of separating media 4 from a medium safe 3 and places this separating medium 4 on top of the left-behind paper sheets 5 stored in the paper sheet storage safe 2. Accordingly, even if paper sheets are left behind again at the takeout port and the paper sheets are stored in the paper sheet storage safe 2, these paper sheets are distinguished from the previously stored left-behind paper sheets 5 by the separating medium 4, and thus plural groups of left-behind paper sheets 5 can be stored in the paper sheet storage safe 2.

Abstract: PURPOSE: To carry out a pseudo dynamic BT test by setting oscillation frequencies of a first and second oscillation circuits slightly different from each other in a memory inputting addresses via a group of filpflops. CONSTITUTION: In a BT mode, with a BT signal 50 set in a BT mode and a shift mode signal set in a shift mode, an oscillation circuit 5 generates a frequency f1 and an oscillation circuit 6 generates a frequency f2 slightly different from the frequency f1 (f2=f1+Δf).

Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To improve the vertical resolution apparently and make a stroke stronger by applying to 2nd source wiring with an applied potential which is an intermediate potential between the potentials applied to two pieces of source wiring and reversed in polarity. SOLUTION: An intermediate potential generating circuit 62 produces an intermediate potential between those of conventional neighbor data output lines 17 from them and reversed in polarity. When the resistance of a resistor 65 is made twice that of a resistor 66, Yn of conventional data output line 17 and the new data output line Zn satisfy a relation Z1=-(Y1+Y2)/2, and an intermediate potential with polarity opposite to that of the conventional data output line 17 is outputted from a new data output line 61. The outputs Y1-Yn of the conventional data output lines 17 are connected with conventional source wiring 3 on a liquid crystal panel, and the outputs Z1-Zn of the new data output lines are connected with source wiring.  Thus, a liquid crystal display device can be realized where the vertical resolution is apparently twice as high as the conventional resolution and is strong against a stroke.

Abstract: PROBLEM TO BE SOLVED: To provide a golf cart that never fails to stop with a defined distance by aid of a cart-guarding detecting means when another golf cart or an obstacle approaches from ahead. SOLUTION: An obstacle or a golf cart approaching from ahead is detected by a cart-guarding detecting means.
