Patent EP-0064937-A3 (EP)
Title: Method and construction of sail boards and surfboards
IPC: B63B5/24
Filed: 1982-05-11
Abstract: According to this method a cellular core (1) is produced, having dimensions smaller to the prescribed dimensions and such size difference is compensated by applying on said core a fiber tissue (2). The space existing between the core (1) and the hull (3, 4) of the board, thus occupied by the tissue (2), is filled with foam in order to form, in the edge area of the core, a highly pressure resistent foam layer reinforced by the fibers, which perfectly binds the rigid hull (3, 4) of the board to the core.

Title: Non-oriented electrical steel sheet having a low watt loss and a high magnetic flux density and a process for producing the same
IPC: C21D8/12
Filed: 1983-01-26
Abstract: In the production of non-oriented electrical steel sheets, it has been attempted to decrese the watt loss, e.g. by adding Sn into silicon steels, but in such a case the relationship between the watt loss and magnetic flux density falls within the curves 1 and 1 min in Fig. 1. The addition of boron is therefore unsatisfactory for meeting the recent demands, for improving the magnetic properties of a non-oriented electrical steel sheet over those indicated by the curve 3. In the present invention, the combined addition Sn with B and/or sol. Al results in development of (110) and (100) textures which are desirable for the magnetic properties. A non-oriented electrical steel sheet according to the present invention, contains 0.015% of C at the highest, from 0.3 to 2.0% of Si, from 0.005 to 0.10% of sol. Al, from 0.02% to 0.20% of Sn, 0.007% of N at the highest, and 0.005% of B at the highest, the weight ratio of B content/N content being from 0.5 to 1.5, said non-oriented electrical sheet being produced by a process comprising an annealing of a hot-rolled steel strip. Instead of B, an appreciable amount of sol. Al may be contained in said sheet, when Mn content is from more than 1.0% to 1.5%.

Abstract: The head positioning system for positioning a magnetic 
head at a target track of a rotating magnetic disk comprises 
a drive motor for driving said magnetic head in a radial 
direction of said magnetic disk, and a position error detector 
for generating a position error signal which indicates a 
deflection of said magnetic head with respect to a center 
line of said target track. A compensation digital filter 
generates a compensation signal having a frequency in­
teger times the disk rotational frequency. A stabilization 
digital filter is connected to said position error detector and 
said compensation digital filter for generating a equilibrium 
point signal of said drive motor in accordance with said 
position error signal and said compensation signal. A motor 
driver determines a drive current of said drive motor in 
response to said equilibrium point signal. A detector detects 
a position of said magnetic head relative to said center line 
of said target track and supplies the head position signal to 
said position error detector. This system positions the mag­
netic head at the center line of a target track with high 
accuracy even if the target track is eccentric. Furthermore, 
the track density of the disk can be increased.
