Filed: 1991-06-18
Abstract: PURPOSE:To contrive an easy way to design, manufacture and install an oil cooler by a method wherein the inside of a header is divided into a plurality of heat exchanging parts separate from one another and a plurality of oil having different functions is passed separately through each heat exchanging part independently of one another. CONSTITUTION:An oil cooler 1 is provided with an upper heat exchanging part 1a for passing engine oil therethrough, an intermediate heat exchanging part 1b for passing power steering oil therethrough and a lower heat exchanging part 1c for passing automatic transmission oil therethrough, whereby such oil flows are produced independently of one another without running together.

Abstract: PURPOSE:To enable miniaturization of a mold clamping device, by a method wherein a rotary motion and linear motion conversion mechanism generating propelling power by turning relatively to a tie bar and its driving device are provided. CONSTITUTION:A rotary motion and linear motion conversion mechanism 36 and a mold breaking and clamping motor driving the conversion mechanism 36 are fixed to a movable platen 34 to move the movable platen along a tie bar. The movable platen 34 possesses a rotary member 53 supported turnably freely by bearings 51, 52 and the rotary member 53 possesses an annular recessed part 57 so as to face on a tie bar 5. A rotator 58 such as a ball or a roller is held within the annular recessed part 57 and a pattern 60 to generate propelling force to move a rotary member 53 relatively to the tie bar 5 is formed. In other words, when the rotator 58 moves the circumference of the tie bar by following a rotation of the rotary member 53, the movable platen 34 is moved in an axial direction along the tie bar 5. Therefore, since the movable platen can be moved without making use of a link mechanism, size of a mold clamping device can be miniaturized.
