Abstract: PURPOSE:To always obtain an optimum amplification factor by providing a resistor whose resistance is higher than an input impedance of a preamplifier between an input of the preamplifier and a ground level point and supplying a bias current to the resistor so as to increase an input saturation current of the preamplifier. CONSTITUTION:A resistor R whose resistance is much higher than an input impedance of a preamplifier 12 is provided between an input of the preamplifier and a ground level point to supply a bias current IDC to the resistor R in a decreasing direction of an input current IIN. Thus, an input current versus output voltage characteristic shown in solid lines is shifted to the characteristic shown in broken lines and a saturation point P. is shifted to a point P1. As a result, a saturation current of the preamplifier 12 is improved by +IDC. In this case, it is required to take notice of a parasitic capacitance (capacitance between input and ground point of preamplifier 12) of a current source circuit and of an impedance (higher than input impedance of the preamplifier 12) of the current source circuit.

IPC: H04N1/19
Filed: 1986-07-02
Abstract: PURPOSE:To carry and read a manuscript smoothly, by providing a stopper member to regulate the quantity of separating a contact type sensor from a read roller. CONSTITUTION:At the time of inserting a thick manuscript 3, the contact type sensor 5 is separated from the read roller 1 to a position where it is abutted with the stopper member 8, by a mutual function between the strength of the hardness of the manuscript 3, and a pressing spring 4. At this time, when the quantity of separation (delta) is small even if the contact type sensor 5 is separated from the read roller 1, the read roller 1 can supply an enough carrying force on the manuscript 3. Thus, since the quantity of separating the contact type sensor 5 from the read roller 1 is limited by the stopper member 8, it is possible to carry the manuscript 3 even if a guide member is separated from the read roller 1.

Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To lessen a size of a filter structure required for a multi-system mobile communication means, by forcing at least either one of a first or second conductors to transmit a control voltage into contact with a piezo-electric layer, and by making them perform a switching function in response to a control voltage. SOLUTION: A bridge structure of a switch is formed by a layer 100 of a piezo-electric material, a first conductor 110 and a second conductor 120 to apply a DC control voltage and supply a RF signal to the piezo-electric layer 100, a contact conductor 112, an acoustic mirror structure 150a, 150b to insulate these BAW structures from a base 200, and the base 200. If a high voltage is applied between the second conductor 120 on the top part and the first conductor 110 on the bottom part, electrostatic force generated bends the piezo-electric layer 100. If the piezo-electric layer 100 is bent, the contact conductor 112 is brought into contact with the first conductor 110 on the bottom part, and it can be used for a resonator. This resonator and the switch structure are advantageously used at a frequency of not less than 400 MHz.

IPC: H04N7/169
Filed: 1994-07-06
Abstract: PURPOSE: To obtain a decoding and deciphering method by which an introduced error can be corrected by deducing a sampling frequency for reception based on a prescribed expression and adjusting the address of a cutting point, and then, advancing or lagging the phase in sampling. CONSTITUTION: An A/D converter 100 deduces a sampling frequency fr for reception which is lower than a sampling frequency fo for transmission based on an expression fr =(q/p)fo (where, (e) and (q) respectively represent integers). A false random sequence generator 400 introduces an address position in chrominance memories C1 and C2 against a new axis of abscissa by using (b) as the integer which is closest to the computed results of a'=(p/q)a (where, (a) represents the axis of abscissa) and (g) as the decimal part of a'. Then MAC video signals are rotated in the direction opposite to the direction in which the signals are rotated prior to transmission and a write counter 300 writes chrominance components in the memories C1 and C2 and luminance components in memories Y1 and Y2 .  The writing corresponds to the start of the chrominance components and, when g<=0.5, the phase fr is advanced by (g). When g>0.5, the phase fr is lagged by (1-g).
