Filed: 1986-06-12
Abstract: PURPOSE:To obtain a test disk with high quality by adhering a metallic foil with a prescribed thickness to a clamping region so as to obtain a desired warp on a signal region. CONSTITUTION:The metallic foil 10 made of stainless steel or bronze is adhered to a clamping region 9 at the read face side 8 of a disk 1 by a thermosetting or cyanobond group adhesives. The thickness of the foil 10 is decided by a desired warp and the warp on the signal region with 0.3-0.5mm gives its effect on the tracing performance of a player, then the thickness of the foil is selected to be 0.05-0.15mm to make the warp test disk. In placing the test disk on a turntable 12 of a spindle motor 11, the table 12 and the foil 10 are contacted and the thickness of the foil 10 determines the warp in the reproducing region signal of the optical pickup 13 proportionally.

Title: Opening arrangement
Inventor: KENSU YAKOBUSON
IPC: B65D5/06
Filed: 1986-06-12
Abstract: Non-returnable packages for liquid contents, e.g. milk, are made frequently from a flexible packing laminate, and are provided with an opening arrangement in the form of a tear-off strip which covers a pouring opening in the packing container wall. So as to avoid spatter and spillage at the actual moment of opening an opening arrangement for packing containers is realized comprising a pouring opening (8) which has a projection (8') of small area directed against the direction of tearing of the tearing strip (6). This part of the pouring opening (8) formed as a projection (8') thus will be opened first, and airwill flow into the packing container, and the liquid level will drop so that the continued opening can be performed without any risk of spillage. By varying the sealing strength between the tearing strip and the packing laminate an automatic delay of the removal of the tearing strip after the opening of the projecting part can be achieved, which further improves the functioning of the opening arrangement.

Abstract: PROBLEM TO BE SOLVED: To promote introduction of seawater from the outside of a port to the inside of the port while the back side of a breakwater is kept calm by providing a bank with a water guide hole pierced from the front side to the backside, and providing a screen plate in a place at a suitable space from the front of the bank. SOLUTION: A bank 1 is provided with a water guide hole pierced from the front side thereof to the back side thereof. An impermeable screen plate 3 is provided in a place in front of the water guide hole 2 and at a suitable space from the front of the bank 1. In this case, the upper end of the screen plate 3 is positioned near the seawater surface, and the lower end is fitted to a footing 4 to form a seawater introducing part 5. Accordingly when waves collide with a breakwater, in front of the screen plate 3, the sea level makes wave motion vertically round the still water level S.W.L., but the wave motion of the sea level of the seawater introducing part 5 will not be under the height of the upper end of the screen plate 3.  Thus a water head difference is produced between the front side of the bank l and the back side thereof so that seawater in the seawater introducing part 5 is introduced into the port 6 in the rear of the breakwater through the water guide hole 2.
