Title: Semiconductor storage device
Inventor: YAMAKOSHI HIROYUKI
IPC: G11C8/16
Filed: 1988-06-27
Abstract: PURPOSE:To reduce an influence of the inter-line capacity and to increase the storage capacity by providing an earth shield line between complementary data lines. CONSTITUTION:An earth shield line 5 is arranged between data lines 2 and 3 out of dual port complementary data lines 1 and 2 and lines 3 and 4 of adjacent arrays, and earth shield lines 34 and 35 are arranged on the outside of data lines 1 and 4. When a word select signal 6 is activated, a level difference is generated between data lines 1 and 2 in accordance with data stored in a memory cell 10. Though a word select signal 7 is activated to generate a level difference between data lines 3 and 4 at this time, the data line 2 has not an influence because the inter-line capacity between data lines 2 and 3 is small. Consequently, the access is not limited between ports, and the storage capacity is increased.

Title: Reproducing device for recording disk
Inventor: HASEGAWA KAZUO
IPC: G11B17/028
Filed: 1981-10-05
Abstract: PURPOSE:To rotate a disk stably by forming air holes, which communicate with the gap formed by a recording disk, at the external circumference of a turntable. CONSTITUTION:At the external circumference of a turntable 4, air holes 4c are formed. When the turntable 4 is rotated by a motor 3, the air in space 7 flows toward the external circumference by inertia, but when the resistance of flowing in the air holes 4c is less than that in the gap 4b between a disk 1 and the outermost circumference of the turntable 4, the air flows out of the air holes 4c in a direction C. At this time, air flows in the space 7 through an air hole 4a in a direction B, but the air flows out in the direction, so the disk 1 rotates stably without floating over the turntable 4.

Title: Noise eliminating circuit of television receiver
Inventor: ISOBE MITSUO
IPC: H04N5/213
Filed: 1977-12-27
Abstract: PURPOSE: To make it possible to eliminate noises definitely without causing a lockout phenomenon by detecting noises which exceed a synchronization peak value and by feeding them back while decreasing the gain of a common amplifier circuit by the output.  
     CONSTITUTION: If the output of video detection circuit 5 contains noise signal VN 1  in the black direction above synchronization peak value V s  of a video signal (a), noise detection circuit 1 detects a noise exceeding reference voltage Vref 1  and outputs pulse (b) of ΔT in width, so that since video intermediate-frequency ViF amplifier circuit 4 has its gain decreased or made zero only in a pulse period of ΔT, output signals, namely, input signals to circuit 5 which contain noises will all be eliminated (c) in period ΔT. In this way, since signal TN 1 (a) exceeding V s  of a video signal is converted into noise VN 2 ' (d) [the output signal of circuit 5] in the white direction, AGC detection circuit 3 becomes able to detect only V s  and, in consequence, normal operation is maintained invariably in addition to the definite prevention of a lockout phenomenon.
