Inventor: KOMATSU MASUO
IPC: G02F1/1345
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a method for fabricating a semiconductor device in which a short circuit caused by fragments of a test pattern is prevented at the time of mounting the semiconductor device by improving the dicing process of a semiconductor wafer, and the yield of an electrooptic device mounting the semiconductor device can be enhanced. SOLUTION: Along the scribe line on a semiconductor wafer 360, a groove 363 is formed using a cutter blade 201 thicker than the width of a test pattern 362 on the semiconductor wafer and then the inside of the groove 363 is cut by means of a thinner cutter blade 202. Since the test pattern 362 is removed completely by forming the groove 363, generation of fragments of the test pattern 362 is prevented at the time of cutting the wafer.

Title: Radio equipment and method for compensating distortion of wave transmitted by the same
Inventor: MORIYAMA YUKIHIRO
IPC: H04L27/36
Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To improve the performance of distortion compensation by eliminating the necessity of an orthogonal detector for detecting the distortion amount of a transmitted modulation wave, miniaturizing a device, reducing power consumption and price and eliminating the necessity of complicated offset compensation in respect to digital radio equipment and its distortion compensation method. SOLUTION: An operation control part 1-1 compensates the distortion of a transmission base band signal of I and Q components and sends the compensated signal to an orthogonal modulator 1-3. A transmission modulated wave outputted from the modulator 1-3 is amplified suffering non-linear distortion by a power amplifier 1-4 and sent through an antenna 1-5. An output signal from the power amplifier 1-4 is branched, the amplitude of the signal is detected by a mixer 1-6 on the basis of the reference carrier of the I (or Q) component and fed back to an operational amplifier 1-1. The operational amplifier 1-1 successively receives the transmitting base band signals of the two orthogonal I and Q components and successively calculates an amplitude distortion amount and a phase distortion amount on the basis of the feedback signals of the base band signals.  Then the operational amplifier 1-1 calculates a distortion compensation amount on the basis of these distortion amounts and applies reverse distortion to the transmission base band signals to compensate the distortion.

Abstract: PROBLEM TO BE SOLVED: To ensure detection of an obstacle without malfunction due to surrounding environment. SOLUTION: Two digital monitoring cameras 11a, 11b are used to trap polygonal images in a preset monitoring region, which are three-dimensionally processed by a three-dimensional image processing part 21. A difference between the image generated by the three-dimensional processing and a background image in the preset monitoring region stored in a background image storage part 23 is picked up for extracting a monitored object from the image with a background portion removed. This monitored object is analyzed by an analysis part 22 to judge whether the monitored object is an obstacle or not from the information of the three-dimensional image. If it is an obstacle, alarm information is output to an external alarm system through a data interface part 24.  Such a detecting system utilizing the image prevents malfunction which may be caused in a conventional system utilizing an infrared ray and ensures detection of an obstacle.
