摘要:
A vehicular automatic transmission including a first planetary gear device and a first set of frictional coupling elements, which can be supported by a pump housing via first and second retainer rings, at predetermined axial positions within the pump housing, during assembling of the automatic transmission. The first retainer ring is fixed to a radially inner spline-fitting part of a cylindrical extending portion of the pump housing, while the second retainer ring is fitted in a first circumferential groove formed in a ring gear of the first planetary gear device and a second circumferential groove formed in the inner circumferential surface of a splined cylindrical portion of a first hub splined to the outer circumferential surface of the ring gear and the radially inner portions of the first set of frictional coupling elements. The automatic transmission is manufactured by assembling a subassembly with respect to a stationary cylindrical housing to which the pump housing is fixed. The subassembly includes the pump housing provided with an oil pump, first planetary gear device and first set of frictional coupling elements.

A mirror device includes a mirror (153) which is supported to be pivotable with respect to a mirror substrate (151), a driving electrode (103-1-103-4) which is formed on an electrode substrate (101) facing the mirror substrate, and an antistatic structure (106) which is arranged in a space between the mirror and the electrode substrate. This structure can fix the potential of the lower surface of the mirror and suppress drift of the mirror by applying a second potential to the antistatic structure.

摘要:
Integrated correlation values (I and Q integrated correlation values) between each of I and Q signals obtained from a received signal and a code replica are calculated by a coherent integration process performed by a correlation process circuit section 32. A coherent integration enhancement circuit section converts a phase angle θ of each of the I and Q integrated correlation values (IQ coordinate values) into a double angle, and further integrates the converted I and Q integrated correlation values (IQ coordinate values) to calculate I and Q enhanced integrated correlation values. An incoherent integration circuit section performs an incoherent integration process on the I and Q enhanced integrated correlation values. A coherent integration time T1 of the correlation circuit section is set to be 20 ms or less, and an integration time T2 of the coherent integration enhancement circuit section is set to be longer than 20 ms.
摘要:
A method of forming patterns on transparent substrates using a pulsed laser is disclosed. Various embodiments include an ultrashort pulsed laser, a substrate that is transparent to the laser wavelength, and a target plate. The laser beam is guided through the transparent substrate and focused on the target surface. The target material is ablated by the laser and is deposited on the opposite substrate surface. A pattern, for example a gray scale image, is formed by scanning the laser beam relative to the target. Variations of the laser beam scan speed and scan line density control the material deposition and change the optical properties of the deposited patterns, creating a visual effect of gray scale. In some embodiments patterns may be formed on a portion of a microelectronic device during a fabrication process. In some embodiments high repetition rate picoseconds and nanosecond sources are configured to produce the patterns.
