Title: Magnetic recorder and reproducer
Inventor: TSUJI TAKAO
IPC: G11B5/02
Filed: 1981-05-01
Abstract: PURPOSE:To perform magnetic recording of short wavelength, by locating main magnetic poles at almost equal angular intervals circumferentially, rotating them in a prescribed rotating speed and arranging an auxiliary magnetic pole along the rotating locus of the main magnetic poles through clipping a magnetic recording medium. CONSTITUTION:A main magnetic pole 1 is respectively fixed to rotating arms 8a-8c at the lower tip arranged at almost equal angular intervals circumferentially. On the other hand, an auxiliary magnetic pole 4 is arranged by clipping a magnetic recording medium 6 in opposition, the shape is a circular arc and corresponds to the rotating locus of the main magnetic poles 1. When the rotating arms 8a-8c are rotated, the main magnetic pole 1 turns in circular arc from one end to another end of the medium 6, and when the main magnetic pole 1 passes through the other end, the next main magnetic pole 1 opposes to one end of the medium 6. Similarly, the main magnetic poles 1 sequentially pass through along the surface of the medium 6 to form vertical magnetic recording tracks in circular arc with a specified pitch to the magnetic substance layer of the medium 6. Thus, the relative speed between the main magnetic poles 1 and the medium 6 is increased to perform the magnetic recording in a short wavelength.

Filed: 1982-04-20
Abstract: PURPOSE:To enhance surface property and traveling performance, etc., by using a saponified vinyl chloride-vinyl acetate copolymer consisting of 1-8wt% vinyl alcohol component, <=2wt% residual vinyl acetate component, as the binder of a magnetic layer. CONSTITUTION:When vinyl alcohol component is >=8wt%, enhancement of surface property slows down, deterioration of orientation degree increases.

Title: Multi-input josephson and gate, multi-input josephson or gate, josephson decoder circuit and josephson pla circuit
Inventor: SUZUKI HIDEO
IPC: H03K19/195
Filed: 1992-03-24
Abstract: PURPOSE:To improve the reliability by connecting quantum interference elements in cascade and giving a bias current to elements of 2nd and succeeding states while being corresponding to the transition to a definite voltage state. CONSTITUTION:When transiting to a definite voltage state, Josephson junction elements J1-J5 output a voltage corresponding to a gap voltage. Thus, a bias current fed to a quantum interference element Si corresponding to the element Ji depends definitely on a resistance of a resistor Ri2. Since the element Si has only a single input line and a sufficient operating margin is ensured, it is not required to synchronize an input current with the transition caused sequentially from the 1st stage to the final stage and a sufficient time margin for the transition progressed sequentially is obtained. Thus, the multi-input AND gate and the multi-input OR gate with high operation reliability are formed.
