Title: Optical waveguide, method for aligning lens and optical waveguide, device for aligning lens and optical waveguide, wireless optical communication equipment and recording medium
Inventor: SHIMONAKA ATSUSHI
IPC: H04B10/07
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To provide the method and device capable of precisely aligning the lens and optical waveguide. SOLUTION: The beam spot 106 which is converged by a condenser lens 104 and travels toward the projection end surface of an optical waveguide layer 102 is picked up by a CCD 103. In its image pattern, interference fringes are observed which are different in cycle with the distance between the beam spot 106 and the top surface of a substrate 101. Namely, this results from that when the beam spot 106 is above the top surface of the optical waveguide, the interference fringes are observed owing to the interference between light made incident directly on the CCD 103 and light reflected by the top surface of the optical waveguide. For the purpose, the condenser lens 102 is moved along a Y axis over a look at the screen of a monitor 107 to position the interference fringes along the Y axis.

Title: Nonvolatile semiconductor memory
Inventor: KOBAYASHI KAZUO
IPC: H01L29/792
Filed: 1988-03-08
Abstract: PURPOSE:To avoid the delay of access time at the time of reading/writing despite the large capacity of the title memory sharing a column latch in divided column lines. CONSTITUTION:A nonvolatile semiconductor memory contains a memory cell array consisting of memory cells allocated in both row and column directions in the form of an array and the column latches set for each column line. Then the semiconductor memory is divided into two memory cell arrays MA11 and MA12 (MA21, MA22) of (m/2Xn) constitution respectively and these cell arrays share a column latch CL1. Thus the wiring capacity can be halved for the column lines (bit line, control gate line) of a memory cell array. As a result, the time required for charging/discharging the column lines can be extremely reduced and the access time is shortened to satisfactorily cope with the large capacity.
