Title: Amplification circuit arrangement
Inventor: DESUMONDO ROSU AAMUSUTORONGU
IPC: H03F1/30
Filed: 1988-12-23
Abstract: PURPOSE: To enable constitution using a transistor(TR) of the same conductivity type by selecting resistance values of four resistances and the gain of a current amplifying circuit so that the voltage at the output terminal of a 2nd stage is almost irrelevant to variation in the potential at a 1st voltage reference point with the point at a 2nd voltage reference point during operation. CONSTITUTION: A 1st stage 1 is equipped with a long-tail pair of npn TRs 3 and 4. The collector electrodes of the TRs 3 and 4 are connected to the 1st voltage reference point 5 through 1st and 2nd resistances 6 and 7 and the common connection emitter is connected to the 2nd voltage reference point 8 through a current source 9. The 2nd stage 2 is equipped with a current amplifying circuit 10 in the style of what is called a current mirror circuit. When the potential at the point varies with the potential at the point 8, the base current of a TR 13 varies and a current flowing through the input current path of a resistance 14 and an amplifier 10 varies.  The resistances R6 , R7 , R14 , and R16 and the current gain of the amplifier 10 are properly selected for the current gains B13 and B15 of TRs, and then the potential variation of an output terminal 17 to the point 5 becomes nearly equal to (v).

Title: Carrier synchronization system
Inventor: ONISHI MAKOTO
IPC: H04L27/22
Filed: 1992-12-03
Abstract: PURPOSE:To attain high speed synchronization pull-in, to improve the data transmission efficiency and a jitter characteristic in a synchronization capture state by selecting an optimum loop filter coefficient in the synchronization pull-in state and the synchronization latch state while keeping a PLL control coefficient to be constant so as to set an internal variable of a PLL. CONSTITUTION:Loop filter coefficients a0, a1, b are selected to satisfy the relation of zeta>1 and to increase an angular frequency omegan for a decreased pull-in time in equations of omega0=(Komega1)<1/2> and zeta=omegan/2 (omegan is a natural angular frequency of a PLL and zeta is a control coefficient). A content of a register 15 is stored at pull-in and an output of the PLL is observed to obtain a change in a phase phi. The coefficients a0, a1, b and internal variables DELTAomega, phi are decided in the step of initial parameter setting in the synchronization lock loop. However, the loop filter coefficients are set to decrease a loop noise band BL in which the zeta is unchanged from the pull-in state. The variable DELTAomega is calculated again newly. The phase phi is set to the sum of an input phase error DELTAphi1 and the observed phi. Thus, the convergence is quickened and the pull-in time is decreased.

IPC: B41J2/30
Filed: 1993-12-22
Abstract: PURPOSE:To prevent a printing result from becoming light or blurred by applying an impact to a platen by sufficiently large force by combining the displacement due to a foreshock and the displacement due to normal driving input by preliminarily applying a foreshock to a head pin to slightly displace the same. CONSTITUTION:A head pin 83 is replaced toward a platen 9. When foreshock driving input is eliminated, the head pin 83 is mainly displaced in the direction opposite to the platen 9 by the elasticity of a transmission mechanism 82 and again displaced toward the platen 9, that is, vibrated. In this state, a drive element 81 is driven by the normal driving input based on printing data supporting printing to generate displacement. The head pin 83 is largely displaced by this displacement and the displacement generated by the foreshock driving input to remain. By this constitution, even in the case of a first dot, an impact is applied to the platen by sufficiently large force.
