A gusset bag (10), having a pair of flat surface portions (11, 11) facing each other and a pair of side surface portions (12, 12) facing each other which are folded toward the inside, has a side edge sealing portion (13) in which the flat surface portion and the side surface portion are heat-sealed together at side edge portions thereof, and a folded-back portion (13c) in which all or a part of the side edge sealing portion in the width direction is folded back toward the flat surface portion or the side surface portion. The gusset bag and a spout-attached gusset bag (1) using the gusset bag have an excellent self-standing property, and causes one's hand to feel little pain even when being squeezed.

In a liquid crystal display device, there is provided a liquid crystal display panel in which a TFT substrate and a counter substrate are bonded together by a sealing material, with a liquid crystal sandwiched between the substrates. Further, a front window with a black border print formed in the periphery is bonded to the liquid crystal display panel by a UV curable resin. The liquid crystal, is filled by a drop method. The thickness of the TFT substrate and the counter substrate is reduced to about 0.2 mm toy polishing. An inner end of the black border print of the front window is inside an inner end of the sealing material, to prevent the counter substrate of the liquid crystal display panel from being deformed by stress generated In the curing of the UV curable resin, thereby preventing yellow discoloration in the periphery of the display area.

The problem to be solved by the present invention is to provide a method for continuously and effectively producing an aliphatic polyester having an increased molecular weight which prevents evaporation of diisocyanate at the step of mixing the diisocyanate with the aliphatic polyester prepolymer in a molten state at a temperature not lower than the melting point of the prepolymer and enables uniform mixing of the diisocyanate with the aliphatic polyester prepolymer. In order to solve this problem, the present invention provides a method for producing an aliphatic polyester having an increased molecular weight comprising the steps of: (i) quantitatively injecting a diisocyanate into an aliphatic polyester prepolymer which has a number average molecular weight of 5000 or higher and has terminal hydroxyl groups and in which at least one acid component is a succinic acid compound, in a molten state at a temperature not lower than the melting point thereof, wherein the amount of diisocyanate is equivalent to between one tenth and two times the amount of the hydroxyl groups in the aliphatic polyester prepolymer, (ii) quantitatively and continuously mixing the diisocyanate-containing aliphatic polyester prepolymer obtained at step (i) by a static mixer, discharging same from the static mixer, and then supplying same to a coupling reaction tank, and (iii) reacting the aliphatic polyester prepolymer with the diisocyanate in the coupling reaction tank.

A display device which can ensure sufficient adhesive strength between each pair of substrates of a liquid crystal display panel and a sealing material includes: a first substrate having a predetermined integrated circuit; a second substrate on one surface of the first substrate in an overlapping manner; and an adhesive material between the first substrate and the second substrate that has an annular planar shape. The adhesive material adheres the first substrate and the second substrate, wherein an outer periphery of the adhesive material includes a zone which includes a plurality of first portions passing substantially the same position as an outer periphery of the surface of the first substrate and a plurality of second portions each connected with the two neighboring first portions and having a center portion thereof in a peripheral direction retracted toward an inner peripheral side of the adhesive material.

An engagement fixture of a shoulder belt is connected to and supported by an engagement buckle disposed in a vehicle interior. When a platform is positioned in a getting in/out position in a vehicle exterior, the engagement fixture of the shoulder belt can be temporarily connected to a temporary fastening fixture provided to the platform. To the contrary, when the platform is positioned in a loading position in a vehicle interior, a connection condition of the engagement fixture of the shoulder belt can be changed from a temporary connection of the fastening fixture to a securely supportable connection of an engagement buckle in the vehicle interior. Thus, it is possible to simplify a belt attaching operation after a wheelchair is loaded in a vehicle while a columnar support member used in the conventional platform is abolished.
