摘要:
A vortex flowmeter comprising ultrasonic wave transmitters and ultrasonic wave receivers adapted to receive ultrasonic waves transmitted by the transmitters through a flow of fluid in which vortices are generated by a vortex generator, the ultrasonic wave signals output by the ultrasonic wave receivers being compared by a phase comparator to measure the flow rate of the fluid by detecting the difference in phase of the ultrasonic waves due to generation of the vortices. First and second ultrasonic wave transmitters are disposed on the wall of a pipe line defining the flow path for the fluid downstream of the vortex generator and first and second ultrasonic wave receivers are respectively disposed at positions on the wall of the pipe line opposite to the first and second transmitters and in such a manner that the first propagation route for the ultrasonic waves propagating from the first ultrasonic wave transmitter to the first ultrasonic wave receiver and the second propagation route for ultrasonic waves propagating from the second ultrasonic wave transmitter to the second ultrasonic wave receiver intersect each other and extend in opposite directions. The phase of the respective ultrasonic wave signals output by the first and second ultrasonic wave receivers are compared by a phase comparator so that the vortices generated by the vortex generator can be detected.

A method of vacuum-assisted RTM includes disposing a resin distribution medium on one surface of a reinforcing-fiber substrate, covering the whole with a bag material, reducing the pressure inside the bag material, and injecting a resin into the resin distribution medium to distribute the resin substantially in in-plane directions and then impregnate the resin into the reinforcing-fiber substrate in the thickness direction. The method is characterized in that the flow resistance of the resin distribution medium itself during resin distribution is changed in in-plane directions of the reinforcing-fiber substrate, in accordance with a difference in fiber weight per unit area or density between parts to be impregnated with resin of the reinforcing-fiber substrate present in a plane direction of the reinforcing-fiber substrate, or in accordance with a difference in distance from a resin impregnation initiation part to a resin impregnation completion part between parts to be impregnated with resin of the reinforcing-fiber substrate present in a plane direction of the reinforcing-fiber substrate.

A press molding system (1) may include a first press molding apparatus (2) and a second press molding apparatus (3). When a material (M3) molded by the first press molding apparatus (2) is conveyed to the second press molding apparatus (3), an orientation of the material may be changed simultaneously with the conveyance from an orientation taken when conveyed out of the first press molding apparatus (2) to a desired orientation for the second press molding apparatus (3).

A method for processing a separation and rupture portion of a display label is a method for forming, on the display label attached to an attachment target object, the separation and rupture portion for rupturing the display label upon separation of the display label from the attachment target object. This method includes attaching, to the attachment target object, the display label having a back side on which an adhesive layer is formed, and then forming a slit serving as the separation and rupture portion on the display label.
摘要:
A method of RTM molding wherein a reinforcing fiber substrate is placed in a mold, each of a first and a second resin distribution media exhibiting a resin flow resistance lower than the resistance of the reinforcing fiber substrate is placed on each surface of the reinforcing fiber substrate, and the inside of the mold is evacuated and a resin is injected into the mold to thereby impregnate the reinforcing fiber substrate with the resin injected, characterized in that the first resin distribution medium exhibits a resin flow resistance lower than that of the second resin distribution medium, and the evacuation is carried out through the second resin distribution medium while the resin is injected through the first resin distribution medium. The method can be advantageously employed for producing, in particular, FRP structure which is thick and excellent in designability, lightweight property and/or strength.

A magnetic tape cassette and a guide roller in which the magnetic tape can stably travel and the magnetic head can read/write the record correctly, and a method of manufacturing the guide roller are provided. The magnetic tape cassette of the present invention comprises a guide roller 106 rotatably supported by the lower cassette half. The guide roller is almost in the shape of a barrel of which a coefficient of curvature T expressed by the expression [1] representing the extent of curvature of the circumferential surface is in the range between 0.001 and 0.01, and comprises a primary molding and injected resin injected within the primary molding for bulging said primary molding into the shape of said barrel shaped cavity that has a largest diameter at the parting line by the injection pressure.
摘要:
A three-dimensional weaving machine that enables biased yarn guide blocks to be reduced in size and their movement to be simplified and that reliably feeds biased yarns is described. A three-dimensional mechanism contains 2N guide blocks (13), each including a biased yarn through-hole (15) extending along the length direction. A guide block receiving and supporting device (18) forms guide block arrangement spaces (S1), (S2), and (S3) in a bottom stage, a middle stage, and a top stage wherein N of the 2N guide blocks can be arranged in each stage parallel with, and adjacent to, one another. A guide block moving device (22) is provided for moving the guide blocks in each stage in opposite directions along the respective stages, and a shifting device (44) operates for simultaneously shifting two adjacent sets of guide blocks movably arranged in the respective guide block arrangement spaces, each by one stage.
摘要:
A magnetic tape cassette in which a mechanism for engaging a guard panel with a lower cassette half is simplified, the assembly process thereof is highly efficient, and the cassette is produced inexpensively and with excellent productivity. The magnetic tape cassette is constructed such that an engagement hole is formed on the inner surface of a side wall of a guard panel, and an engagement piece is formed on a side of the casette case and defined by a U-shaped slit so as to flex about a proximal end in the left and right directions relative to the cassette case. A locked state releasing projection and an engagement projection extend from the engagement piece. The engagement projection is engaged with the engagement hole when the guard is closed. The locked state releasing projection extends beyond the side wall of the guard panel and is used for releasing the engagement projection from the engagement hole. In another embodiment, the engagement projection is formed on a side wall of the cassette case, without the U-shaped slit, for engagement with the engagement hole. The engagement projection is removed from the engagement hole with a shift rod of a conventional tape deck.
