Title: Printing plate and letterpress printing method
Inventor: DEIITERU GIYURUSU
IPC: B41N1/12
Filed: 1988-09-07
Abstract: PURPOSE: To provide a quantitatively controlled ink feeder by specifying the critical surface tension of an ink bearing printing section and forming a printing section formed of plastic. CONSTITUTION: When an ink bearing printing section is of oil and water repellence and has low dampening characteristics and/or when the ink bearing printing section specifically has about 18-30 mN/m critical surface tension, said section can be made of very small critical surface tension or oil repellence or water repellence or low ink dampening plastic. Accordingly, the reduction of the ink transfer movement on the printing late section by reducing the minimum possible level surface tension enables the letter press printing with only a small volume of the ink and further, the excellent ink flow enables the inking application thereto in a very short time. The low ink absorption of the printing plate facilitates the removal of the ink from the printing plate.

IPC: G05D3/12
Filed: 1985-10-08
Abstract: PURPOSE:To heighten accuracy of response of the mechanism by passing a vibration acceleration signal of the direction of movement of a movable mechanism to stationary coordinate system through band-pass filters.

Title: Automatic frequency controller
Inventor: ISHIKAWA MITSURU
IPC: H03J7/02
Filed: 1987-09-09
Abstract: PURPOSE:To prevent AFC lock-on to a higher harmonic component of a main signal by interrupting the AFC system when a component of an AFCIF signal near the specified frequency is smaller than an undesired signal component of a low frequency. CONSTITUTION:The AFC IC signal is given to a power divider 5, and distributed into a discriminator 3 and a low pass filter 6. The signal given to the discriminator 3 causes a shift from the specified center frequency of the AFC IF signal and the shift is outputted in a form of a DC voltage. On the other hand, the AFC IF signal given to the low pass filter 6 is subject to cut-off of the component near the specified center frequency and the result is inputted to a detection sample and hold circuit 7. The DC voltage subject to detection and sample and hold is inputted to a comparator 8, compared with a reference voltage and when the level of the undesired signal is larger than the level of the AFC IF signal from the specified center frequency signal, a control signal interrupting a switch 9 is sent. Thus, the AFC system is cut off.

Abstract: PURPOSE:To measure the variation of cutting torque with high precision by installing a noncontact-type speed detector, retreat-difference calculating circuit connected in series with the speed detector, clock-pulse generator connected to the calculating circuit, and a cutting-torque calculating circuit. CONSTITUTION:If the revolution speed of a main shaft 1 reduces with the increase of cutting resistance during working for a workpiece, the output cycle of a rectangular-wave signal increases in correspondence with the reduction of the revolution speed, and the rectangular-wave signal is converted to an analogue signal by a frequency/voltage converter 7.
