Title: Optical equipment
Inventor: ICHISE HARUNOBU
IPC: G02B7/08
Filed: 2009-04-09
Abstract: <P>PROBLEM TO BE SOLVED: To prevent the occurrence of a tooth jump phenomenon resulting in defocusing which occurs when an impact in an optical direction is applied to a camera when the position of a movable lens group is controlled by a stepping motor.  <P>SOLUTION: The light shielding portion 39 of a variator moving frame 13 used for reset has a repeated pattern of the shape of a recess and projection teeth that match thread ridge pitches of a lead screw. Consequently, how many teeth corresponding to ridges of the lead screw have jumped can be detected. By detecting the amount of the tooth jump, the variator moving frame 13 can be returned to its original position.  <P>COPYRIGHT: (C)2011,JPO&INPIT

IPC: H01L21/336
Filed: 2009-04-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide an alternative form of an FET capable of exhibiting an improved value of current gain cutoff frequency f<SB>T</SB>.  <P>SOLUTION: The field effect transistor (FET) is of the type which employs base biasing to depress the intrinsic contribution to conduction and reduce leakage current. It incorporates four successive layers 102 to 108: a p<SP>+</SP>InSb base layer 102, a p<SP>+</SP>InAlSb barrier layer 104, a π intrinsic layer 106 and an insulating SiO<SB>2</SB>layer 108; p<SP>+</SP>source and drain regions 110 and 112 are formed in the intrinsic layer 106 by ion implantation. The FET is an enhancement mode MISFET 100 in which biasing establishes the FET channel in the intrinsic layer 106. The insulating layer 108 has a substantially flat surface supporting a gate contact 116. This avoids or reduces departures from channel straightness caused by intrusion of a gate groove, and enables a high value of current gain cutoff frequency to be obtained.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide transceivers, including receivers, and methods of communicating OFDM signals that provide flexibility between throughput and range in wireless local area networks (WLANs).  <P>SOLUTION: Modern digital communication system, including WLANs, uses symbol-modulated orthogonal subcarriers as a modulation system to help signals survive in environments having multi-path reflections and/or strong interference. A reconfigurable multichannel receiver can selectively operate in increased throughput modes and/or increased range modes. The receiver can select two or more antennas to receive more than one subchannel of a wideband orthogonal frequency division multiplexed (OFDM) channel. Maximum-ratio combining can be performed on corresponding symbol-modulated subcarriers from the two or more antennas, and a single OFDM symbol can be generated from the subchannels received by the two or more antennas. In other embodiments, more than one subchannel of a wideband OFDM channel can be received through a single antenna selected from a plurality of spatially diverse antennas.  <P>COPYRIGHT: (C)2009,JPO&INPIT
