Patent JP-S61205149-A (JP)
Title: Printing head
Inventor: OOYAMA SHIGERU
IPC: B41J2/295
Filed: 1985-03-07
Abstract: PURPOSE:To provide a printing of high reliability, by a method wherein a piezoelectric element is employed for a displacement generating mechanism and also a printing wire is driven with use of a displacement amplification mechanism. CONSTITUTION:When a character or a symbol, etc. is printed, application of voltage on a piezoelectric element 1b leads the piezoelectric element 1b to be abruptly displaced in the direction of the arrow A. At this time, the tip portion of a lever 2b cannot sufficiently follow the response of the piezoelectric clement 1b because of inertia force, which results in previous displacement of only the center portion thereof. As the piezoelectric element 1b is held in extended condition, the strain energy, stored in the lever 2b caused by the spring force, drives a printing wire 5 in the direction of the arrow B by the snap force caused by the strain energy. The printing wire 5 is so forced as to freely fly by the snap force to conduct printing. After printing is completed, the vibration caused from return of the lever 2b is abruptly reduced by the action of a damping member 2c.

In this course of time, force requied for driving the pump 24 acts as a load against the rotational force of the turntable 2, and rapidly weakens the rotational force, and finally the turntable 2 stops. Thus the lubricat ing oil can be effectively supplied to the sliding surface of the turntable.

Title: Signal detector of signal synchronizing system
Inventor: IWASAKI HARUHISA
IPC: H04L27/22
Filed: 1990-02-27
Abstract: PURPOSE:To take synchronization quickly by comparing an output power from plural correlation devices with a threshold level, detecting the correlation device whose output power exceeds the threshold level and estimating a frequency difference corresponding to the selected correlation device as a frequency error of an input signal. CONSTITUTION:N sets of correlation devices 11-1N are connected in parallel with a terminal receiving an input signal and comparators 21-2N are respectively connected to the correlation devices 11-1N. Then outputs of the comparators 21-2N are inputted to a mutual comparator 3, where the outputs are compared mutually. The comparators 21-2N compare output power of the correlation devices 11-1N with a preset threshold level respectively and when the output power exceeds the threshold level, the frequency error of the correlation device is estimated to be a frequency error of the input signal. Furthermore, when the power outputs from the plural correlation devices exceed simultaneously the threshold level, the mutual comparator 3 compares the power outputs mutually to specify the maximum output power and the frequency error relating to the correlation device corresponding to the maximum output power is estimated to be the frequency error of the input signal, then the synchronization is taken quickly.

Abstract: PURPOSE:To reduce return light from a recording medium to a light source side at the time of reproducing and to lower the occurrence of noise by making a light beam incident obliquely to the face normal of the recording medium at the time of reproducing, and scanning in the direction in which projected component on the face of the recording medium becomes reverse to that of the time of recording. CONSTITUTION:Light beam 20 incident on an objective lens 14 from a light source side passes a position parallel to and off from the optic axis of the objective lens 14, and a recorded pit 21 on the recording medium is deeper in depth, steeper in gradient and larger in width at the end of writing than at the beginning of writing. When reproducing information, light beam 22 for reproduction is projected on the recording face of a light card 1 obliquely to a position parallel to and off from the optic axis through the lens 14. Projection component to the recording face at this time is made nearly reverse to the direction of scanning of a light beam spot to the recording face at the time of recording. Thereby, scattered light (shown by dotted lines) of light beam incident on an information pit 21 does not go back to the direction of incidence, and return light is not generated.
