Title: Remote observation device for temperature at multiple points
Inventor: SASAKI KIYOSHI
IPC: G01K1/02
Filed: 1984-12-18
Abstract: PURPOSE:To provide the simplification and higher reliability of a circuit of a transmission part to be installed and to obtain an observation device which permits temp. measurement with the higher accuracy by selecting plural temp. sensors in such a manner that the frequency bands of the output signals thereof are not superposed on each other. CONSTITUTION:Temp. sensors 31-33 which vary in the frequency of electric output signals in follow up to a temp. change are so selected that the frequency bands of the output signals of the respective temp. sensors are not the same within the temp. measurement range at three points. Counter circuits 34-36 select and count the output signals of the corresponding temp. sensors from the multiplexed reception signals. A control circuit 37 has a clocking function and controls the count time of the circuits 34-36 to respectively different count time. Non-linear circuits 38-40 correct equivalently the respective tracking characteristics of the temp. sensors 31-33 to predetermined characteristics and display circuits 41-43 display temp. The frequency bands of the output signals are so selected as not to overlap on each other within the measuring temp. range in the above-mentioned manner and therefore the frequency multiplexing is made possible without the modulation operation in the signal transmission part.

Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To reduce deteriorated image quality by generating an interpolation scanning line signal through in-field interpolation when a detection motion vector is in motion of horizontal panning.

A parameter setting section 3 sets an inter-frame interpolation filter mixing ratio 1-K and an in-field interpolation filter mixture rate K based on the signals S2, S3 to provide a output of a signal S4. A frame interpolation filter 4 and an in-field interpolation filter 5 generate interpolation signals S5, S6 based on each pass frequency characteristic.  Coefficient weight sections 6-1, 2 multiply the signals S5, S6 with ratios 1-K, K respectively, the products are added by an adder section 7, which provides an output of a signal S7. A delay section 8 is used to adjust a delay in the processing time for the processing as above to provide an output of a signal S8. A multiplexer section 9 applies half compression to the signals S7, S8 with respect to a time base and conducts time division multiplex to obtain an image signal S9.

Filed: 1987-10-20
Abstract: PURPOSE:To prevent the infiltration of O2 and H2O into an amorphous magnetic film by sandwiching the magnetic film by layers which can hermetically seal the magnetic film against the O2 and H2O. CONSTITUTION:This recording medium is constituted by laminating an O2 and H2O impermeable layer 2 selected from a group consisting of a fluorine- containing resin layer and silicon-contained resin layer, a magneto-optical recording layer and a protective layer 6 in this order on a substrate 1. Plastic, glass, ceramics, etc., are used for the substrate 1 and the known fluorine-contained resin layer and silicon-contained resin layer are usable for the impermeable layer 2. The recording layer may also be constituted of a dielectric layer 4 and the magnetic layer 5. The dielectric layer which does not contain the O2 is produced from a dielectric substrate and the amorphous magnetic layer 5 from a transition metal and rare earth, both by a sputtering method or vapor deposition method. The protective layer 6 is produced from Au, Pt, Ni, Cr, etc., having resistance to oxidation and corrosion or alloy of these metals and metals having a relatively small thermal conductivity by a sputtering method or vapor deposition method. The infiltration of the H2O and O2 is thereby prevented.

Title: Heat treatment within magnetic field
Inventor: MITANI SATORU
IPC: H01F10/00
Filed: 1987-10-23
Abstract: PURPOSE:To facilitate to provide a magnetic thin film having any arbitrary shape with magnetic anisotropy at any arbitrary position so that the magnetic thin film can have an axis of easy magnetization in a direction as desired, by disposing the magnetic thin film within a DC magnetic field and applying a laser beam to the surface thereof for heating the magnetic thin film locally. CONSTITUTION:A magnetic core 6 is formed for example in a ring shape and DC magnetic field is applied thereto in the direction as indicated by the arrow X. A laser beam is applied to the surface of the iron core 6 along a zigzag path 8 extending transversely across almost all of the width of the magnetic core 6. The radiating position of the laser beam is moved in the peripheral direction in a range of about + or -15 deg. with respect to the direction of the DC magnetic field. Then, the direction of applying the DC magnetic filed is changed to the one as indicated by the arrow Y that has been rotated by 30 deg. from the direction of the arrow X. Such operation is repeated by rotating the direction of DC magnetic field by 30 deg. at a time. In this manner, it is made possible to provide the whole ring-shaped iron core 6 with magnetic anisotropy with axes of easy magnetization distributed approximately radially.

Title: Thin film coil for magnetic head
Inventor: OTOMO MOICHI
IPC: G11B5/31
Filed: 1987-10-23
Abstract: PURPOSE:To reduce the resistance of a thin film coil by increasing gradually a coil width from an inner circumferential coil to an outer circumferential coil and optimizing the width ratio of an outer-most circumferential coil and an inner-most circumferential coil and the width of a rear part coil area. CONSTITUTION:A thin film coil is formed by the long outer circumferential coil of a coil length per turn and the short inner circumferential coil part. Then, the width of the coil is gradually increased from the inner circumference to the outer circumference and the cross section of the long part of the coil length per turn is made larger. Consequently, the resistance of the outer circumferential part is reduced and the resistance of the coil as a whole is decreased. In order not to worsen the characteristic, it is not necessary to reduce the magnetic length of a head, prevent the deterioration of a recording/reproducing characteristic and not to minimize the number of heads able to be made from a constant raw material. In front part, side part and rear part coil area width FW, CL and BW, the width ratio of the outer-most circumferential and inner- most circumferential coils and the width BW are optimized. Thus, a magnetic head excellent in the characteristic and having a low resistance can be mass-produced.
