Title: Magnetic recording and reproducing device
Inventor: SAKAMOTO ETSURO
IPC: H04N5/7826
Filed: 1990-10-11
Abstract: PURPOSE:To eliminate crosstalk by setting an initial phase of a frequency modulation signal for each H so that a difference between a difference of initial phases of a prescribed track and its adjacent track at a prescribed H and a difference of initial phases of the prescribed track and its adjacent track at one preceding H is pi. CONSTITUTION:An encoder 4 applies time division multiplex to a luminance signal component and a chrominance signal component, emphasis circuits 7, 27 shuffle the signal subject to time division multiplex into plural tracks for each H and FM modulators 9, 29 apply frequency modulate to the shuffled signal by using prescribed carrier. Then a phase comparators 12, 32 and a timing signal generating circuit 14 set the initial phases of the frequency- modulated signals for each H to a state that a difference between a difference of initial phases of a prescribed track and its adjacent track at a prescribed H and a difference of initial phases of the prescribed track and its adjacent track at one preceding H is pi. Thus, crosstalk component is eliminated.

Title: Surface acoustic wave element
Inventor: EGARA KOUICHI
IPC: H03H9/70
Filed: 1990-10-11
Abstract: PURPOSE:To eliminate adverse effect on the characteristic of a surface acoustic wave element of a surface acoustic wave reflected in the end face by randomizing a distance between end faces of the same side of each guide path in the direction crossing a propagation direction of a 3rd surface acoustic wave of each surface acoustic wave guide path. CONSTITUTION:Surface acoustic wave guide paths 4-1-4-n are formed in such a way that the distance between centers is equal to a wavelength lambda of a surface acoustic wave to be generated and a distance between end faces I and II of two adjacent guide paths in the surface acoustic wave guide paths 4-1-4-n is formed at random. Then a 3rd surface acoustic wave propagated in the direction (y) is converted into an electric signal by an acoustoelectric converter 5, part of the 3rd surface acoustic wave is reflected returned in the acoustoelectric converter 5 and reflected in each end face I of the surface acoustic wave guide paths 4-1-4-n again. Since the distance among the end faces I is entirely randomized, the phase of the reflected surface acoustic wave is entirely randomized and the synthesized reflecting waves are cancelled to each other. Thus, the reflecting wave generated in the end face is suppressed and the characteristic of the element is improved.

Abstract: PROBLEM TO BE SOLVED: To prevent a water leaking arising from a bottom face bedewing or raining by bonding an insulant to the bottom face of a steel plate and wave forming them together and, making crest portions of the top part of the steel plate are self held at practically the same plane. SOLUTION: When the wave forming is conducted, the steel plate is compressed upward via the insulant and bent towards the bottom face side along the center lines and side lines in parallel to the center lines of each top part of the upper face.

For example, a flat steel plate 1 is wade formed by bonding such an insulate 2 as a high expanded polyethylene and the like to the bottom face of a galva steel plate 1 (an alloy of Fe and Al) and by inserting it into the roll forming device.  The insulant 2 alleviates a sharp curving due to a protrusion, and a smooth wave form is formed and this status can be self held.
