  • Patent number: 10576700
    Abstract: A first continuous fiber component and a second continuous fiber component are stacked with a non-woven fabric interposed therebetween to thereby prepare a fiber base material. The fiber base material is placed between an upper mold and a lower mold. The upper mold and the lower mold are brought close to each other to thereby form an enclosed space therebetween. The enclosed space is larger in volume than a product cavity. A liquid matrix resin is supplied to the enclosed space. The upper mold and the lower mold are brought closer to each other to thereby form the product cavity in a manner that a pressing load is applied to the fiber base material. Then, the liquid matrix resin with which the fiber base material has been impregnated is hardened in the product cavity, whereby a fiber-reinforced plastic molded article is produced.

  • Patent number: 7717075
    Abstract: No-load valve lift correction curves of opening and closing cams are set by offsetting no-load curve sections of basic valve lift curves of the cams in such directions as to increase a clearance between the curves, and they are connected with remaining sections of the curves to provide normal valve lift curves of the cams. Cam profiles of the cams are set on the basis of such normal valve lift curves. The cam profiles are set so that an ultimate speed difference between jumping and landing speeds of a follower on an ultimate valve speed curve determined from ultimate valve lift curves, having first and second shift sections where the follower shifts from the opening cam to the closing cam and from the closing cam to the opening cam, is smaller than a basic speed difference between jumping and landing speeds on a basic valve speed curve.

  • Patent number: 7443876
    Abstract: A plurality of information processing terminals 100 to 130 are connected to a network. Each processing terminal parameter-manages the total of the idle time units obtained through the detection of the idle time on the network. The processing terminal acquires a transmission privilege when the parameter and its own node ID agree with each other, and sends out the transmission frame inclusive of its own node ID to the network. The reception means 105 receives, from the network, the transmission frame transmitted from the other information processing terminals. The control means 103 extracts the node ID included in the transmission frame thus received and updates the parameter to the node thus extracted, and adjusts the synchronization of the parameters commonly possessed on the same network. In accordance with such a configuration, the transmission privilege can be rounded without exchanging a token frame between specified nodes.

  • Patent number: 7406911
    Abstract: An expander (M) employing steam as a working medium is formed from a first radially inner group of axial piston cylinders (49) arranged annularly on a rotor (27) so as to surround the axis (L) of an output shaft (28), and a second radially outer group of axial piston cylinders (57) arranged annularly so as to surround the first group of axial piston cylinders (49). The first and second groups of axial piston cylinders (49, 57) are driven by a common swash plate (39), and the first and second groups of axial piston cylinders (49, 57) are arranged with circumferentially displaced pitches. High-temperature, high-pressure steam firstly operates the first group of axial piston cylinders (49), then operates the second group of axial piston cylinders (57), and the outputs from the two are combined to drive the output shaft (28). This achieves a further reduction in the size and a further increase in the output of the axial type expander (M).

  • Patent number: 7159400
    Abstract: When a flow of a working medium stagnates in an expander or evaporator of a Rankine cycle apparatus including a closed working medium circulation circuit, a high pressure exceeding an allowable maximum pressure level of the expander or evaporator is produced within the closed working medium circulation circuit. In such a case, the water-phase working medium is first discharged via relief valves out of the circulation circuit, so that the pressure within the circulation circuit can be lowered. Then, once vapor within the evaporator, having been lowered in temperature and pressure, flows backward within the closed working medium circulation circuit, the vapor is also discharged via the relief valves out of the circulation circuit. In this way, the pressure within the expander or evaporator can be reliably prevented from exceeding the allowable maximum pressure level.

  • Patent number: 7117691
    Abstract: In a liquid-level-position control device for a condenser in a Rankine cycle apparatus, first and second reference liquid level positions are set. When a position of the fluid level is lower than the first reference liquid level position, water is replenished to a condenser by a liquid-phase working medium supply section. When the position of the fluid level is higher than the second reference liquid level position, the liquid-phase working medium is discharged from within the condenser by a liquid-phase working medium discharge section. In this way, the liquid level, which is a boundary surface between water vapor and condensed water within the condenser, can be constantly kept at an optimal position.

  • Publication number: 20050158181
    Abstract: An expander is provided in which a rotor (22) is rotated by supplying high-temperature, high-pressure steam to an expansion chamber (43) defined between a piston (42) and a cylinder sleeve (41) so that the piston (42) pushes a swash plate (31). Since an annular heat-insulating space (70) is formed in a rotor head (38) facing the expansion chamber (43), it is possible to suppress the escape, to the rotor (22), of the heat of high-temperature, high-pressure steam supplied to the expansion chamber (43), thereby preventing the heat efficiency from deteriorating.
