Disclosed herein are simulated fibrous tissue models of anatomical parts for surgical training. The non-dissolvable simulated fibrous tissue model is made of a polyvinyl alcohol (PVA) and fibrous material composite to simulate realistic tissue properties and behaviors. The simulated fibrous tissue model may be a standalone model of an anatomical part or may be used in a complementary anatomical simulation kit to provide a more comprehensive training approach.

In the ultrasonic welding method, ultrasonic vibration is imparted to a first resin member via a horn while applying a pressing force to the first resin member and a second resin member in which weld portions and come into contact with each other by using a jig for supporting the second resin member and the horn that is disposed to face the jig and in contact with the first resin member so as to weld the first resin member and the second resin member, in which a jig of which a support surface for supporting the second resin member is formed of an elastomer is used as the jig.

A polyvinyl acetal poly(vinyl acetal), such as polyvinyl butyral, resin formulation, a method of extruding poly(vinyl acetal) resins, and related materials and products that provide for monolithic poly(vinyl acetal) sheets and glass panes having high Tg of at least 50 C. and high modulus at acceptable rates as indicated by their high melt flow index. This is made possible by a reduction in the amount of plasticizer while using a low molecular weight resin not to exceed 160,000 to obtain a thermoplastic resin having a high melt flow index and high Tg. The articles made with these monolithic interlayer sheets can be used in applications that require good modulus at outdoor temperatures.

An expansion device, including: an installation unit in which a thermally expandable sheet is disposed; an irradiation unit configured to irradiate the thermally expandable sheet placed on the installation unit with light; and a control unit configured to perform processes described below, wherein after an expansion process to expand the thermally expandable sheet by irradiating the thermally expandable sheet placed on the installation unit with light by the irradiation unit, a cooling process to cool the thermally expandable sheet by a predetermined cooling unit while maintaining the state in which the thermally expandable sheet is placed on the installation unit.

An expansion device, including: an irradiation unit configured to irradiate the thermally expandable sheet placed on a placing unit with light; a conveyance unit configured to reciprocably convey the irradiation unit between a first position and a second position; an exhaust fan fixed to a housing and configured to discharge air from the housing; and an air supply fan which is movable with the irradiation unit and configured to supply outside air into the housing, wherein the exhaust fan is provided at a position where air can be discharged from the second position side when the irradiation unit is returned from the first position to the second position after being moved from the second position toward the first position.

A method to make dyed functional film comprising the steps of providing a soluble polymer material; adding an appropriate solvent to the polymer material to make a soluble polymer solution; providing a soluble dye; adding an appropriate solvent to the dye to make a soluble dye solution; adding the dye solution to the polymer or PVA solution, and introducing the dyed polymer or PVA solution to a solution casting device; removing a thin dyed functional film from the casting device; and letting the dyed functional film dry and solidified.

There is provided an interlayer film for laminated glass with which an air bubble can be made difficult to be left behind between a lamination glass member and the interlayer film when laminated glass is obtained. The interlayer film for laminated glass according to the present invention contains a thermoplastic resin and has a portion where the amount of increase in the thickness is increased in a direction from one end to the other end in the region where the thickness is increased, has a portion where the amount of increase in the thickness is decreased in a direction from one end to the other end in the region where the thickness is increased, has a portion where the wedge angle is increased in a direction from one end to the other end in the region where the sectional shape in the thickness direction is a wedge-like shape, or has a portion where the wedge angle is decreased in a direction from one end to the other end in the region where the sectional shape in the thickness direction is a wedge-like shape, and the ten-point average roughness Rz of the surface at a center position of the portion where the amount of increase in the thickness is increased, the portion where the amount of increase in the thickness is decreased, the portion where the wedge angle is increased, or the portion where the wedge angle is decreased is 20 m or more.

A mold assembly has a pressing mold, a shunt cone, and a mold cap. The shunt cone is disposed in the pressing mold to define a conical pressing channel. The shunt cone has a body, an inlet channel, and an outlet channel. The body has a conical cone portion. The inlet channel has an extension height from a top of shunt cone being higher than an extension height of the inlet channel from the top of the shunt cone. The mold cap is attached to a bottom of the pressing mold and has a lower mold cavity to allow the cone portion to extend into the lower mold cavity and to define a conical shaped connection channel. The connection channel communicates with the pressing channel, and a material input channel is defined in the mold cap and communicating with the connection channel.
