Title: Magnetic recorder
Inventor: KITADA MASAHIRO
IPC: G11B21/21
Filed: 1987-04-06
Abstract: PURPOSE:To always float a head on a medium whether they are relatively moved or not, by using a superconductor as materials of a part or the whole of a supporting body which supports or floats the magnetic head. CONSTITUTION:A head slider part 1 is made from a superconductor with respect to the head consisting of the head slider 1, a magnetic head part 2, a magnetic gap part 3, and a floating surface 4. Since a magnetic flux 6 from the recording medium is eliminated by the effect of complete diamagnetism because the slider part 1 of the magnetic head is made from the superconductor, the slider is not brought into contact with the recording medium. Thus, the medium and the head are not brought into contact with each other even if they are stopped, and they are not slided at the time of stopping or driving, and the head and the medium are not damaged.

Title: Automatic circulating paper feeder for original
Inventor: IKEDA SUNAO
IPC: G03G15/04
Filed: 1987-04-03
Abstract: PURPOSE:To feed and convey an original continuously in matching with a copying speed by installing a switchback turnover conveying mechanism in a position being distant of more than the maximum original length from a stopping tip position at an original exposure part, in the midway of a discharge conveyor, while installing a transfer gate device thereat. CONSTITUTION:In case of a single-sided original, by way of example, if exposure is finished on a certain original 20, it is discharged out by way of a turnover conveying mechanism 31 and a discharge conveyor 40. At this time, since length up to the extent of getting into a switchback turnover mechanism 47 is longer than the maximum original length, there is no overlap with each other even if there is the preceding original 20 this switchback turnover mechanism 47, so that continuous paper discharging can be done. On the other hand, the paper feeding conveyance onto contact glass 11 is also in the same manner, that is paper feeding can be done simultaneously with completion of exposure of the preceding original 20. Thus, the original 20 is conveyable into a conveying passage ranging from the paper feeding to the paper discharging continuously in making it match with a copying speed at the side of a copying machine body 10, so that there is no paper feeding at all and, what is more, down time is reducible.

Title: Package for ic
Inventor: KIMURA YUKIHIRO
IPC: H01L23/14
Filed: 1991-04-16
Abstract: PURPOSE:To realize high density conductor columns and the reduction of crosstalk by surrounding a conductor column, in a dielectric substrate, with a metallization layer with a dielectric layer sandwiched therebetween. CONSTITUTION:An IC package 1 is provided with a dielectric substrate 2 in the form of a thin laminate and a plurality of conductor columns 3 which pass through the substrate 2. The inner wall of the part of a hole 2a, through which the conductor column 3 of the substrate 2 passes, is coated with a metallization layer 6. The inner surface of this metallization layer 6 is covered with a dielectric layer 11 for electrically isolating the conductor column 3 from the metallization layer 6. With this arrangement, the conductor column 3 is completely and electrically shielded by means of the metallization layer 6 for grounding purposes, and the characteristic impedance of the conductor columns 3 can be matched, as a result reflected noises of a signal are reduced, and the IC package 1 which is superior in signal transfer characteristics is obtained. The electrical shielding of the conductor column 3 can be ensured even when the pitch of the conductor columns 3 is reduced, thereby leading to the conductor columns 3 which have a much greater density and the IC package 1 which is reduced in both weight and size.

Title: Diesel exhaust emission controlling catalyst
Inventor: SATO AKEMI
IPC: B01J35/04
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To prevent the outer peripheral of straight-flow type catalyst from suffering from SOF poison and prevent sulfate from being generated at high temperature. SOLUTION: By changing carrier amount of noble metal, average particle diameter of the noble metal, or specific surface of a coat layer in relation to central part and outer peripheral part, oxidation force in the outer peripheral part is higher than that in the central part. Because high oxidation force oxidizes and cleans SOF even when much SOF contacts with the outer peripheral part, a catalyst is prevented from suffering from SOF poison. In addition, because highest temperature exhaust gas flows in the central part where oxidation force is lowest, sulfate is prevented from being generated.
