Abstract: This invention aims to prevent a core from being pushed back when a hydraulic fluid is compressed by a high load occurring with a molding pressure of molten melt at a casting and pressing time in a core driving cylinder in a die cast machine. There are provided a pressure intensifying cylinder 2a for allowing a pressure intensifying chamber 31 to communicate with a head-side cylinder chamber 22 of a working cylinder 1 and its control hydraulic circuit. When a load and a rated pressure Pp of a hydraulic pump 25 are balanced with each other at the time of inserting and setting a core 41, a check valve 21 is closed and a sequence valve 34 is opened to move the pressure intensifying cylinder 2a forward, so that the pressure of the head-side cylinder chamber 22 is increased. A pressure intensifying ratio of the pressure intensifying cylinder 2a is set such that the pressure of the head-side cylinder chamber 22 is higher than pressure occurring with molding pressure. A maximum discharge volume is set to a value being equivalent to a compression quantity of the hydraulic fluid of the chamber 22, and advancement of the pressure intensifying cylinder 2a automatically compensates for the above compression quantity.

Abstract: This specification disclosed a partially closed microfluidic system and a fluid driving method. The microfluidic system is comprised of a substrate with microfluidic elements and a thin film. A feature of this structure is that the thin film is elastic and deformable. It has a single opening corresponding to a vent hole on the substrate, thus forming a partially closed microfluidic system. The substrate is designed to have several positions for micro fluid elements and deformable chambers and uses micro channels to form a complete network. Since the thin film is elastic and deformable, one is able to impose a pressure on the thin film above the deformable chambers in this partially closed microfluidic system to drive the fluid into motion. Once the pressure is released, the fluid flows back to its original configuration.

Abstract: A control lever for operating a control system of a vehicle, such as a brake or clutch of a motorcycle, for example. The lever is especially useful with hydraulic control systems, for applying a force to a hydraulic piston of the control system. Preferably, the lever includes an engagement portion that contacts an end surface of the piston. The engagement portion may be free to rotate with respect to a body portion of the lever such that the engagement portion rolls across the end surface of the piston. Such an arrangement provides improved lever nullfeelnull and substantially prevents transverse loading of the piston. The engagement portion may also include a protruding arm that engages the end surface of the piston, for use with hydraulic control systems where the piston is recessed within a housing.

Abstract: A master cylinder for the clutch or brake of a motor vehicle has a housing for a reciprocable piston one end of which receives the spherical head of a reciprocable piston rod. The head is held in a desired position relative to the piston by a one-piece or composite coupling device having a first section exerting a pull or bearing upon the head of the piston rod and a second section which is confined in or surrounds the end of the piston and urges the first section in a direction to hold the piston rod against axial movements relative to the piston. The coupling device and/or the piston are or can be made of a plastic material, and the connection between such parts is or can be established by snap action.
