Title: Agc circuit
Inventor: OOHASHI TAMAKI
IPC: H03G1/00
Filed: 1982-11-16
Abstract: PURPOSE:To input an input radio wave by connecting the primary coil of the 1st magnetic circuit in series with a voltage detecting coil of the 2nd magnetic circuit so as to form a voltage drop coil and extracting a difference of effective voltage generated between the secondary coil of the 1st magnetic circuit and the voltage drop coil. CONSTITUTION:The primary coil L1 of the 1st magnetic circuit 1 and the voltage detecting coil Ls of the 2nd magnetic circuit 2 are connected between a signal input point X and ground in series to form a voltage drop coil LD. Since an AGC signal is increased when an input signal is larger, a DC voltage given to a DC control coil LDC1 via an inversely proportional amplifier circuit 3 is lower and a voltage generated in the secondary coil L2 is higher. Since a DC voltage given to a DC control coil LDC2 via a proportional amplifier circuit 4 is higher in the 2nd magnetic circuit 2, the inductance of the voltage detecting coil LS is smaller, and a voltage generated in the voltage detecting coil LS is lower. Thus, a large input signal is suppressed.

On receiving the control signals, the auxiliary controlling part 30 stops rotation of pulse motor 33, 34, thereby stopping feeding of a thermal transfer ribbon. In this case, the thermal transfer ribbon is stopped, and only a paper is fed a one-line distance.

IPC: B60G3/28
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a rear suspension device which is excellent in the layout and which is also excellent in the suspension performance. SOLUTION: Since one end of a lateral link member 14 is installed in the intermediate part of a radius arm member 10, the change in the angle of the lateral link member 14 per unit stroke amount in a vehicle backface view is smaller in comparison with a case where the lateral link member is directly installed in a wheel supporting body 8. Thus, the change in the height of a roll center due to the stroke of the lateral link member is reduced in conformity with a reduction in the change in angle of the lateral link member 14 due to the stroke in a vehicle backface view, and thus a rear suspension device which is excellent in the layout and which is also excellent in the suspension performance, can be obtained.
