Title: Production of powdery polyisocyanate compound
Inventor: WATANABE YOSHIAKI
IPC: C08G18/72
Filed: 1995-01-27
Abstract: PURPOSE: To produce a powdery polyisocyanate compound having free isocyanate groups by a simple process without much loss during production by reacting a specified silicon dioxide compound with a specified amount of a polyisocyanate in a solid phase. CONSTITUTION: 15-70 pts.wt. silicon dioxide compound containing at least 50wt.% silicon dioxide component and having an oil absorption of 100ml/100g or above is reacted with 85-30 pts.wt. polyisocyanate to obtain a powdery polyisocyanate compound having free isocyanate groups. The obtained compound has excellent long-term stability of its isocyanate groups, a small particle diameter, good powder flowing properties and little blocking property. The production process comprises feeding a dehydrated and dried silicon dioxide compound into a mixing/reactor, feeding a heated polyisocyanate in a liquid state and mixing and reacting the mixture at 30-120 deg.C for 10min to 8hr.  The progress of the reaction can be followed by measuring the concentration of the NCO groups, and the NCO concentration decreases to one corresponding to about 5-40% of the NCO concentration of the unreacted mixture when the reaction is complete.

Title: Wall panel for basement
Inventor: NODA SABURO
IPC: E04B2/00
Filed: 1995-03-07
Abstract: PURPOSE: To improve performance of a wall panel for basement by sticking a bent steel plate such as a keystone plate on a frame consisting of a pair of upper and lower horizontal frames and a pair of left and right vertical frames and being made of steel, and covering a space surrounded by the horizontal frames and the vertical frames with a waterproof surface plate. CONSTITUTION: A wall panel is fixed onto the top face of the sill of a basement while placing a waterproof layer composed of a surface plate 39 on the outdoor side. The surface plate 39 functions as the waterproof layer interrupting the indoor side and the outdoor side while resisting in-plane shearing force and vertical load at that time. A keystone plate 38 resists earth pressure from the outside. The whole surface of the external side face of the panel is covered with the surface plate 39 made of a metal such as stainless steel having high waterproof capacity, thus preventing the possibility of the infiltration of ground- water. A swelling packing is installed between the panel and the sill, thus improving waterproofness. Accordingly, sufficient bearing force to peripheral earth pressure can be ensured, waterproofness can be enhanced, and the wall panel can be executed at low cost.

Abstract: PURPOSE:To load on a pallet with stabilized attitude and loading way by changing the position of a part according to the shape of a press part with the freely rotatable chuck of a part loading means. CONSTITUTION:After pressing unloaders 1A, 1B approach into a press, clamp a member 1 with chucks 22A, 22B and deliver outside the press by sliding it on skid bars 17A-17C. After stopping at the delivery end, the part 1 is clamped with the advance of the chucks 6A, 6B of loaders 2A, 2B. The part 1 is thereafter moved to the chucks 6A, 6B by unclamping the chucks 22A, 22B of the unloaders 1A, 1B side. The loaders 2A, 2B load the part 1 on the pallet, but in this case the loading position of the part 1 varies according to the rotation of rotary shafts 5A, 5B. It is therefore possible to load on the pallet with most stabilized attitude and loading way according to the shape of the part. On completion of the loading the pallet is delivered with the rotation of a conveyor 8 by opening the claw of opening and closing of a pallet stopper 10.
