Inventor: YANAGI HARUYUKI
IPC: B65H7/02
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To detect a presence or an absence of a recording sheet in a recording device by a simple configuration. SOLUTION: A conveying roller 36 is constituted by covering a core member 36a with a rubber member 36b. A part of the rubber 36b is provided with an electrical conductive section 361 in an annular form. As shown in Fig. (a), many electrical conductive pinch rollers 37 are contacted from above with the surface of the rubber member 36b, one pinch roller 371 of them is contacted with the electrical conductive section 361 and then an electrical conduction between the electrical conductive section 361 and the pinch roller 371 is detected by an electrical conduction state sensing section 321. As shown in Fig. (b), as a recording sheet P is passed through a nip between the transporting roller 36 and the pinch roller 37, the electrical conductive section 361 and the pinch roller 371 are moved away from each other and no electrical conduction occurs between both members.  In turn, the passing of the recording sheet P can be detected by no electrical conduction.

IPC: H04B1/18
Filed: 1995-04-25
Abstract: PURPOSE: To provide a switching circuit of a BS converter which can secure high sensitivity. CONSTITUTION: A BS tuner 1 overlaps a band switching pulse signal with power voltage and supplies it to the BS converter 4 at the time of selecting a high band-side. The BS converter 4 amplifies the pulse signal selected by the filter circuit 11 of the switching circuit 9 in a differential amplifier circuit 12 by ten times, and a rectifier circuit 13 rectifies it. A comparison circuit 14 compares the signal with reference voltage so as to detect the presence or absence of the band switching pulse signal. When the band switching pulse signal is detected, a drive circuit 15 turns on a high band local oscillator 16. When it is not detected, a low band local oscillator 17 is turned on. Thus, a reception signal band is precisely switched and selected by amplifying the band switching pulse signal of about 0.6V by ten times.

Filed: 1990-04-16
Abstract: PURPOSE:To use a demodulation section with a large delay time by subtracting an adjustment width table from a demodulated data value in a central control section so as to obtain directly an object in the automatic gain control. CONSTITUTION:Demodulated data are averaged for 8 cycles. Number of demodulation data to be averaged is able to be increased for the proper use of an adjustment width table 21. The adjustment width table 21 is subtracted from the averaged data to obtain an adjustment quantity. An adjustment value is added to a gain set at present to calculate a new gain from which an object value is to be obtained. The gain of an amplifier section 5 is revised into the new gain. A delay time till a line input signal to be amplified is demodulated is compensated by the new gain. Since the gain adjustment is repeated so long as the gain adjustment signal lasts, number of times of the adjustment is saved.
