Title: Magnetic recording and/or reproducing method
Inventor: IKEDA YOSHITO
IPC: G11B5/127
Filed: 1992-04-17
Abstract: PURPOSE:To improve the recording density by performing recording and reproduction by a magnetic head, whose magnetic gap part core thickness is less than the shortest recording wavelength, in the track width direction of a recording medium so that its air gap length is nearly equal to the shortest recording wavelength. CONSTITUTION:In-surface vertical recording is performed by the ring type magnetic head 2 in a direction crossing the travel direction X of the magnetic tape 1. The head 2 is provided with a gap (g) of air gap length L which is nearly equal to the shortest recording wavelength lambdamin on the magnetic recording medium slide surface 3 of a magnetic core which constitutes a closed magnetic path. The width Tw of a track recorded on the tape 1 by the head 2 is less than the gap length L. Consequently, the gap (g) depends upon the track width Tw, so the gap length L can be made long. Further, the core thickness W corresponds to the gap length of the head in lengthwise recording and can be made less than the shortest recording wavelength lambdamin. Consequently, sufficient recording from short wavelength to long wavelength is enabled and high- density recording is provided.

Title: Camera using film with magnetic storage part
Inventor: TSUJIMOTO SHINICHI
IPC: G11B5/54
Filed: 1991-04-26
Abstract: PURPOSE:To execute excellent magnetic recording and to prevent automatic loading from becoming impossible by providing a means which makes a magnetic head follow the deflection of the width direction of a film at the feeding time of the film and a means which retreats the magnetic head from the traveling surface of the film at the time other than a write/read-out time. CONSTITUTION:A film F is moved in a tunnel while it is deflected in an upper and lower direction. However, a state that the lower end of the film F abuts on a film receiving part 8a is kept by a spring 16. Therefore, the dimentional accuracy of track positions L1-L3 on the film F is secured. Besides, magnetic gaps 4a-4c between the magnetic track of the film F and the magnetic head 4 are secured by springs 30 and 31. When the head 4 is retreated, a retreat lever 23 is moved by a motor through a gear and the bent part 23d thereof is made to enter the lower surface of the rising part 17a of a substrate 17. Then, the substrate 17 integrating the head 4 is lifted.

Title: Soft-nitriding steel
Inventor: KANBARA SUSUMU
IPC: C23C8/32
Filed: 1982-07-16
Abstract: PURPOSE:To obtain the soft-nitriding steel esp. excellent in the toughness of its core part after being soft-nitrided and the ductility of a face hardened layer and having sufficient fatigue strength, by making the steel contain the predetermined ratio of each of C, Si, Mn, Cr, V, soluble Al and N. CONSTITUTION:The soft-nitriding steel comprising, by wt%, 0.15-0.50% C, Si <=1.20%, 0.60-1.30% Mn, Cr <0.20%, 0.05-0.20% V, soluble Al <=0.10%, 0.006- 0.020% N and the balance Fe and inevitable impurities. In said composition, the addition amounts of Cr and Al are remarkably limited below the levels of conventional soft-nitriding steel, to obtain proper face hardness (Hv 500-600) and to remarkably improve the ductility of a face-hardened layer at the same time. The reduction of hardness depth caused by limiting the addition amount of Cr is sufficiently compensated by adding a relatively large amount of V which exhibits the effect to improve fatigue strength, too.

Title: Manufacture of heat insulator and press jig for manufacturing heat insulator
Inventor: HASHIYAMA TOSHIO
IPC: C09J5/10
Filed: 1990-05-14
Abstract: PURPOSE:To manufacture a pressing jig matched to an actual center shell configuration in a short time by pressing a transfer assembly to an outer shell surface before injection of a heat insulator raw material, said transfer assembly comprising many transfer members each being movable. CONSTITUTION:A group of pin assemblies 8 is applied onto a formation part of a shelf receiving lead 4 of an inner box 3 in an outer shell 1, and a group of pins 7 is pressed from the inside of the inner box 3 until an auxiliary jig 9 properly makes contact with a flattened surface of the inner box 3. Thereupon, each pin 7 is movable axially and hence the group of the pins 7 is moved in response to the uneven surface of the outer shell 1. Hereby, the tip ends of the group of the pins 7 provide their state where they go along the uneven surface of the outer shell 1. Thus, an adhesive such as epoxy resin is injected into the back surface of a substrate 5. Once the adhesive 10 is solidified, each pin 7 is restricted in its movement because of its being fixed to the substrate by the adhesive 10. Thus, the unevenness of the surface of the outer shell 1 is transferred to the group of the pins 7.
