Title: Car door frame
Inventor: PIETRO PASONE
IPC: B60J10/79
Filed: 1990-12-27
Granted: 1998-12-01
Abstract: The frame is intended to be mounted on a lower panel of a motor vehicle door. It comprises two uprights, a front upright and a rear upright respectively, joined at their upper ends by a cross member and adapted to define, together with upper edge of the lower panel, a space for the window associated with the door. The uprights 2, 6 and the cross member 4 are formed by at least two shaped elements 10, 12 joined longitudinally so as to form a box structure. The frame can thus assume the desired three-dimensional configuration and its dimensions can vary in the general plane of the door and in the direction perpendicular thereto. The uprights 2, 6 may also extend downwardly so as to constitute a reinforcement for the side edges and portions of the lower edge of the lower panel adjacent thereto.

Inventor: SHIBUYA TAKASHI
IPC: A23L27/30
Filed: 1991-10-07
Granted: 1999-04-01
Abstract: Lactoneotrehalose, a novel saccharide shown by the formula O- beta -D-galactopyranosyl-(1->4)-O- beta -D-glucopyranosyl  alpha -D-glucopyranoside, is prepared by allowing a saccharide-transferring enzyme to act on an aqueous solution containing lactose and amylaceous substance. Lactoneotrehalose is a non-reducing oligosaccharide, extremely stable, readily soluble in water, and substantially free of hygroscopicity, as well as having a satisfiable quality and moderate sweetness. These render lactoneotrehalose very useful in the preparations of orally-administrable products, cosmetics and pharmaceuticals.
