Title: Magnetic recording/reproducing device
Inventor: SAKAI MAKOTO
IPC: H04N5/225
Filed: 1989-08-21
Abstract: PURPOSE:To display a superimposition on a screen at the time of reproduction as occasion demands by recording a main video signal and a superimposition signal respectively in different modulation states on a magnetic tape. CONSTITUTION:At the time of the reproduction, when a regenerative signal 10 from the magnetic tape 9 is inputted respectively to a main video reproducing/converting means 12 and a superimposition reproducing/converting means 14, frequency separation is executed at a main video signal demodulation circuit 34 and a superimposition signal demodulation circuit 36 because of the difference of frequency. Then, a main video reproducing signal 11 and a superimposition reproducing signal 13 are outputted respectively through a main video signal processing circuit 35 and a superimposition signal processing circuit 37. The main video reproducing signal 11 between these two signals is inputted always to a second superimposing means 16, but the superimposition reproducing signal 13 is either inputted or not inputted to the second superimposing means 16 according to the operation of a switching means 15 by the choice of a user. Thus, the superimposition can be either displayed on the screen or deleted from the screen.

Title: Control device of different-thickness rolling position in plate mill
Inventor: MORI TOSHIAKI
IPC: B21B39/14
Filed: 1983-11-14
Abstract: PURPOSE:To improve the accuracy of mill stop at a thickness changing point and the yield of a material by measuring a rolling length by a roll-rotation detector and detecting also the change of an inlet-side sheet-thickness caused by a rolling reaction for the purpose of detecting the mill stop. CONSTITUTION:A rotation signal (n) of rolls 1 detected by a rotation detector 3 is inputted to a rolling-length measuring device 4. A rolling reaction detected by a load cell 5 is inputted to a thickness-changing-point detecting device 6, to output a thickness-changing-point arrival signal. A different-thickness rolling-position control device 7 performs an automatic position control so that the rolls 1 stop at the thickness changing point, estimated by the calculation performed by using a rolling-length signal (l) outputted from the device 4. Further, a motor control device 8 outputs a rolling speed signal so as to reduce the rolling speed as said point approaches the rolls 1. The device 7 outputs a signal for stopping the rolls 1 to the device 8 when the device 6 detects the point. Thus the rolls 1 are accurately stopped at the material-thickness changing point.

IPC: H01L21/822
Filed: 1991-07-31
Abstract: PURPOSE:To provide a gate array semiconductor integrated circuit device which reduces the dispersion of delay times after the wiring design and that shortens the development period. CONSTITUTION:A basic cell is provided in an N-well area 1 and a P-well area 2, and input to the basic cell is carried out through a diffused resistor area 8.

The film 2 is subjected to a first etching step along the pattern 3 to form a pre-molding molybdenum interconnect pattern 4' wherein its upper ends are acute-angled. Pattern edges 5 produced by the pattern 4' are then subjected to a second etching step, whereby the edges 5 are removed to form a molybdenum interconnect pattern 4. As a result, the pattern 4 can have a cross-sectional profile whose step coverage is good.
