Title: Dump door upper fitting of dumped motor-lorry
Inventor: YAMANAKA HIDEHIRO
IPC: B60P1/26
Filed: 1978-11-20
Abstract: PURPOSE:To prevent a bang-off of a gate by use of a control lever of a fastening in swing-free connection with the fittings and a stopper attached on a gate or fixed bar. CONSTITUTION:In a case a rear gate 1 is opened downwards, a cargo pushes the rear gate 1 to pull in the directin of an arrow A. A fastened fittings 5 is turned with the pin 6 to stop at a point before two U-shapes 7, 10 are coincided because of a contact of a handle 15 with a stopper 17. In driving, the contact of the handle 15 with the stopper 17 prevents a turning of the fastened fittings 5 caused by driving vibration. For removal of the pin 6, a shifing lever 13 is turned outwards and upwards a cargo deck to coincide both U-shapes 7, 10 of the fastened fittings 5 and a stay 4.

Abstract: PURPOSE:To enhance membrane capacity by laminating a membrane composed of poly-1-trimethylsilyl-propylene and a membrane composed of a polysiloxane/ styrene copolymer to a polyether sulfone porous support having specific capacity. CONSTITUTION:A membrane composed of poly-1-trimethylsilyl-propylene (PMSP) is laminated to a polyether sulfone porous support wherein a degree of hydrophobicity is 10sec or less and air transmissivity is 20sec/6.45cm<2>, 567g, 10cc or less. The PMSP membrane can be directly and continuously formed to the porous support having those characteristics and, since the pressure loss of the porous support is low and the pressure difference and pressure ratio applied to the PMSP membrane are large, the capacity of the formed membrane becomes high. Further, a membrane composed of a polysiloxane/styrene copolymer is laminated to the support to enhance humidity-resistance characteristics and reliability. By this method, a membrane having mechanical strength and high membrane capacity is obtained.
