Antenna devices are provided comprising antenna structures encapsulated or molded into plastic covers of computing devices to enable wireless communication. For example, one or more antenna structures can be encasulated within, or molded into, a plastic display cover of a portable laptop computer. Embedded antenna designs can include various antenna types that are built using one or more wires or thin metallic strips encapsulated into plastic device covers. Insert/injection molding methods can be used to encapsulate antenna structures in plastic device covers during fabrication of the plastic device covers.

Wireless noise is detected within a time period specifically held after a data packet is wirelessly communicated, where no data is purposefully wirelessly communicated during this time period. The time period may be an inter-frame space (IFS) period within which no data is to be wirelessly communicated, and that is a period waited for prior to accessing a wireless medium over which data is wirelessly communicated. One or more actions are performed to counteract the noise. The frequency at which a liquid crystal display is being driven may be decreased so that harmonics caused thereby that caused the noise are no longer within the wireless communication frequency range. An opposite-in-phase version of the noise may also or alternatively be combined with a signal when data is subsequently wirelessly received. The signal includes a data component and a noise component, the opposite-in-phase version of the noise canceling out the noise component.

In an ophthalmic measuring method, a traceable marker in particulate form is administered to the lachrymal fluid of a subject's eye, and the lachrymal fluid is irradiated with illuminating light. Images of the illuminated lachrymal fluid are electronically captured respectively at different times. Two images from among the captured images are selected, with each of the two selected images displaying the traceable marker. A characteristic point of each of the two selected images is specified. A movement speed of the traceable marker is measured based on positions thereof in the two selected images and on a time difference from specifying the characteristic point of one of the two selected images to specifying the characteristic point of the other of the two selected images. The measured movement speed of the traceable marker is outputted as the movement speed of the lachrymal fluid of the subject's eye.

An object of the present invention is to provide a polypropylene polymer film superior in convenience in handling that does not generate troubles such as wrinkling, elongation or breakage during processing at a high temperature of 80° C. to 120° C., independently of the conveying method used in the drying step, and an adhesive film having the polypropylene polymer film as its carrier. Provided are a polypropylene polymer film, characterized by having a tensile modulus of 300 MPa to 1,000 MPa under an atmosphere at 23° C. and 60 MPa to 120 MPa under an atmosphere at 120° C. and an adhesive film containing it as the carrier.

An apparatus has an antenna distance setting mechanism that sets a distance between a cosmetic cover and a radio antenna. An upper housing and a radio antenna, which has a ground and a radiating element and is movably attached to the upper housing, are covered by a cosmetic cover formed of a dielectric material. An antenna distance setting mechanism includes a radio antenna supporting member, elastic members, and protrusions. The radio antenna-supporting member is movably attached to the upper housing. When the cosmetic cover is attached to the upper housing, an inner wall of the cosmetic cover pushes the ends of the protrusions against an elastic force of the elastic members to set the distance between the radiating element and the inner wall of the cosmetic cover to a predetermined distance.

A pipe coupling member for high-pressure fluid such as liquefied hydrogen includes a seal ring having a highly effective sealing function to prevent leakage of the fluid. The seal ring (72) is set in a seal ring setting space (39) defined by a second radial surface (36) and a seal ring setting surface (38) of a first tubular member (20), a forward end surface of a second tubular member (22), and the outer peripheral surface of a valve seat member (24). A forward end portion of the second tubular member (22) is provided with a communication hole (84) radially penetrating the forward end portion. The pressure of the high-pressure fluid on the downstream side of a valve seat surface (52) causes a fluid path in the second tubular member to be communicated with the sealing ring setting space (39) via the communication hole (84) and via a gap between the seal ring setting surface (38) and the outer peripheral surface of the forward end portion of the second tubular member.

A mixture of fluorine-containing acrylic esters represented by CF3(CF2)nCH2CH2OCOCR1═CH2 wherein R1 is a hydrogen atom, a methyl group or a halogen atom and “n” is an integer of at least zero is subjected to distillation under such conditions that the esters are not polymerized, so as to give a mixture of the esters with a less content of impurities (that is, olefins represented by CF3(CF2)nCH═CH2 and alcohols represented by CF3(CF2)nCH2CH2OH) at a high yield.
摘要:
A vehicular anti-lock control system includes: a ground load calculation section for detecting or estimating a ground load of a wheel; a road surface friction coefficient calculation section for detecting or estimating a road surface friction coefficient; and a reference fluid pressure calculation section for calculating an upper side reference fluid pressure and a lower side reference fluid pressure in anti-lock control based on the ground load and the friction coefficient. The upper and lower side reference fluid pressures are respectively determined to be an upper limit value and a lower limit value of a fluid pressure in anti-lock control. Therefore, it is possible to suppress the amount of change in the fluid pressure during anti-lock control, thus improving the braking effect and the braking feel.
