Title: Pannel of partition
Inventor: OMOTE GOJI
IPC: B32B5/02
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To improve quality by adhering a decoration board with a specified resin layer formed on the surface of its medium density fibrous plate formed by a specified method to both surfaces of paper core. SOLUTION: A fancy or decoration board is adhered to both surfaces of core material made of paper core and a reinforcing member is attached to the circumference to form a pannel. In this case, the decoration board is formed by arranging a polyester resin layer 7 on the surface of a basic layer of medium density fibrous plate 4 formed by pressing wooden fibrous material worked and extracted under a heating condition together with an adhesive, through an adhesive 5 and titanium paper 6. Since the strength of the decoration board is high relatively in comparison with that of a vaneer board, such a pannel that is hollow without a paper core can be used. Accordingly, it is possible to eliminate the surface uneveness in the case of conventional veneer board and form a smooth dense surface, and also reduce scattering in thickness.  Furthermore, since the medium density fiberous plate has a small water absorbing rate, separation of decoration board can be prevented as well as the cost can be reduced.

A commutator current 2i is superimposed on the arc current 'i', so that the arc current is formed into an AC waveform resulting in a sure interruption at a zero-crossing point of the current. If an electrode break speed of the vacuum breaker 7 is delayed, the relay 21 does not operate unless at the opening electrode position where the insulating distance between both electrodes are secured, so that the commutator switch 10 does not make thereby causing no restrike.
