Abstract: PURPOSE:To allow a printing hammer to strike a daisy wheel at a regular printing position, by a method wherein immediately when a fixed time has passed after the daisy wheel performing damped oscillation passed a regular stop position, a printing hammer is driven. CONSTITUTION:When the pulse for switching the last phase is inputted to a motor drive circuit 3, a stepping motor 1 is revolved by one step angle and however, a daisy wheel 2 executes damped oscillation utilizing a regular stop position as its center. At that time, an alternating current V appears in a resistor 35 and is compared with the voltage Vs held in a sample and hold circuit 51 by a comparator 50. After the comparison, the voltage outputted from a passing time point detecting circuit 5 trails and time t3 passes. Then, a drive signal is outputted from CPU 4 and a printing hammer 6d is driven with a printing hammer drive circuit 7. Just after time t4 has elapsed, the daisy wheel 2 is struck by the printing hammer 6d. Therefore, the time point at which the daisy wheel 2 is struck conforms to the time point at which the daisy wheel performing damped oscillation comes to the regular printing position thereof and the printing is carried out at the regular printing position.

Title: Polymer dispersion type liquid crystal optical element
Inventor: GOTO TOMOHISA
IPC: G02F1/137
Filed: 1993-02-09
Abstract: PURPOSE:To provide a polymer dispersion type liquid crystal optical element having high scattering intensity when no voltage is applied in consideration of the fact that the scattering intensity when no voltage is applied is more important than the transparent state when voltage is applied for the polymer dispersion type liquid crystal element to be utilized as a reflection type display.

Abstract: PROBLEM TO BE SOLVED: To provide a control method for an automatic gain control(AGC) loop for avoiding an AGC overshoot or an AGC undershoot in an audio output from a radio receiver. SOLUTION: When the receiver enters a place, when a radio wave obstacle such as an under-path exists and detects a sudden decrease in a signal level, an AGC loop response time is reduced, and a state of the AGC loop before the receiver enters the under-path is stored. In the case that the receiver exist the under-path and restores to an environment where obstacle not exist, the state of the original AGC loop is restored from the stored value, and the receiver immediately obtains a proper reception level.
