摘要:
Application data generated by an ECU is wireless transmitted by a transmission device in a subject vehicle so as to periodically change a communications distance by changing, every transmission timing, at least one of (i) a transmission rate, which is used in transforming a transmission packet into a transmission signal in a modulation section, and (ii) a transmission power, which is configured by an amplification section to amplify the transmission signal. As a result, the data transmission from the subject vehicle can be made (i) in high repetition times with respect to a nearby vehicle having a greater risk of collision (i.e., time to collision being shorter), and (ii) in low repetition times with respect to a distant vehicle having a less risk of collision (i.e., time to collision being longer).

A functional membrane is provided, which has high functionality combined with the gas barrier performance and mechanical strength inherent in a polymer film substrate. In particular, a polymer electrolyte membrane is provided, which is excellent in terms of high proton conductivity and gas barrier performance and is most appropriate to serve as a polymer electrolyte membrane for fuel cells. A method for producing a functional membrane is provided, which comprises: a step of ion irradiation, in which active species are generated in a polymer film substrate containing nonconductive inorganic particles by irradiating the polymer film substrate with high-energy heavy ions to the extent of 104/cm2 to 1014/cm2; and a step of graft polymerization subsequent to the step of ion irradiation, in which one or more monomers selected from group A consisting of monomers containing useful functional groups are added such that the monomers are graft polymerized with the polymer film substrate.

This polishing apparatus includes a head that holds a semiconductor wafer, a polishing pad that polishes a surface to be polished of the semiconductor wafer held by the head, and a dresser that reconditions the polishing pad by cutting the polishing pad. The polishing apparatus polishes a surface to be polished of the semiconductor wafer while causing the head and the polishing pad to rotate and reconditions the polishing pad by use of the dresser before and after polishing the surface to be polished. The polishing apparatus of the present invention supports at least two dressers so that the dressers can rotate on their own axes and further includes a dresser oscillator that causes the dressers to oscillate simultaneously on the polishing pad.
摘要:
A polishing equipment includes a polishing head mounting thereon a wafer and a polishing pad having a polishing surface for polishing the wafer. The polishing surface has a groove for guiding slurry on the polishing surface. The groove has a depth larger in the intermediate area of the polishing surface than in the central area and peripheral area of the polishing surface, in consideration of a higher abrasion rate of the polishing surface in the intermediate area in which the polishing surface is abraded in a larger amount.

A planar array antenna comprises a plurality of antenna elements disposed in a predetermined matrix pattern. Feeders extend from a feed to the antenna elements. High-frequency switches cooperatively open or close the feeders connected to antenna elements of at least one row of the matrix pattern located at both a right-end and a left-end regions of an antenna surface. Switching signals are supplied to the high-frequency switches from switching terminals for alternately activating the associated antenna elements, thereby providing two time-divisional array antennas offset in position by a distance corresponding to the width of at least one row of the antenna elements controlled.

A polishing apparatus includes a polishing pad for polishing a wafer and a polishing head for holding the wafer. The polishing head includes a retainer ring, a membrane sheet, and a head body. The retainer ring retains the wafer in a horizontal direction. The membrane sheet depresses the wafer to the polishing pad. The head body supports the retainer ring and the membrane sheet. The retainer ring includes a fixed retainer ring and a released retainer ring. The released retainer ring is interposed between the inner periphery of the fixed retainer ring and the periphery of the wafer to retain the wafer in the horizontal direction.
摘要:
A polishing device includes a polishing pad for polishing a wafer and a polishing head for holding the wafer. The polishing head has a retainer ring for retaining the wafer in the in-plane direction of the wafer, a membrane sheet for pressing the wafer against the polishing pad, and a head body for supporting the retainer ring and the membrane sheet. The retainer ring has a subordinate retainer member having a ring portion and a plurality of fins extending from the ring portion to retain the peripheral surface of the wafer. The subordinate retainer member has a thickness equal to the thickness of the wafer. The membrane sheet has a diameter larger than the wafer, and presses the wafer and the vicinity of the inner edge of the subordinate retainer member.
