Title: Peristaltic pump
Inventor: PIITAA BAN BENSUKOTEN
IPC: F04C5/00
Filed: 1989-02-23
Abstract: PURPOSE: To obtain a peristaltic pump capable of generating a uniform fluid by providing two sets of drive shaft, roller, wheel and platen. CONSTITUTION: Circular rollers 28, 34 are respectively mounted eccentrically on drive shafts 24, 26, and annular wheels 30, 36 are slidingly suspended at outer peripheries of the roller 28, 34. Further, platens 40, 44 are positioned in such a manner that a distance across a tube of a constant diameter between each of the platens 40, 44 and each of the wheels 30, 36 varies when the drive shaft 24, 26 rotate. When the drive shafts 24, 26 rotate in directions shown by arrows 62 and 64, the wheels 30 and 36 are stationary against each other, so that a tube 16 is normal to the platen 40 or 44, and then the tube 16 is subjected to a force facing the diameter direction. Consequently, a fluid can be delivered in a direction shown by an arrow 90 through the tube 16.

IPC: B60J3/00
Filed: 1995-03-01
Abstract: PURPOSE: To accommodate a curtain in fine arrangement and appearance without narrowing the cabin space by opening a gap between the inner and outer panels at the rear of a cab as a space for accommodating the curtain, and extending curtain rails to inside this accommodation space. CONSTITUTION: An inner panel 7 is cut vertically in a part just before reaching the opening 8 of a door, and the gap between the inner panel 7 and an outer panel 9 is left open to ahead of the car cabin as the curtain accommodation space 11. A trim 10 is furnished which smoothly continues from the door opening 8 to the outer panel 9 between panels. and curtain rails 3, 4 are extended to the accommodation space 11 in such an arrangement as alongside the trim. Because the space between the panels in the rear of the cab is used for accommodation, it is possible to secure good space for accommodating the curtain without narrowing the cabin. Therefore, even a curtain surrounding the cabin in the whole circumference can be accommodated between the panels in fine arrangement and appearance.

Abstract: PURPOSE:To increase the saturation magnetic density of a magnetic core so that an eddy current loss is hardly generated and the generated magnetic flux is intensified by alternately laminating prescribed magnetic material films and insulator films and sandwiching these films by soft magnetic material blocks. CONSTITUTION:The magnetic core 11 at the center of a magnetic head for modulating magnetic fields is sandwiched by a pair of the soft magnetic material blocks 12, 12' and is formed to an E shape.
