Title: Method and apparatus for generating optical pulse
Inventor: TOMOFUJI HIROAKI
IPC: G02F1/225
Filed: 1993-06-18
Abstract: PURPOSE:To generate the optical pulse having a short pulse width wherein chirping is small with a relatively simple constitution with respect to a light pulse generating method and a light pulse generating apparatus, which generate the light pulse having a short pulse width. CONSTITUTION:A light signal from a light-signal output part 7 is inputted into an input end 2 of an optical circuit 1 such as a Mach-Zehnder type optical modulator or optical interferometer. The time difference of DELTAt is imparted between the intensity-modulated light signal or the phase-modulated light signal according to the alternating code signals of '0' and '1', which are transmitted through first and second arms 3 and 4. At an output end 5, either one of the optical signal propagated through the first and second arms 3 and 4 is present or the signals are added and applied in the same phase within the time DELTAt. Within the other time, the signals are offset in the phase relationship. Thus, the light pulse having a short pulse width of DELTAt is generated.

Title: Boring method for lining material of lined pipe and its device
Inventor: NAKAI TAKAAKI
IPC: E03F7/00
Filed: 1987-06-13
Abstract: PURPOSE:To enable works in flowing water by adapting a boring method wherein a hole of a small diameter is bored in the lining material of one side pipe with the insertion accomplished into the other side pipe, following which a saw blade is inserted into the hole made so as to enlarge the outer circumference thereof to a diameter roughly equal to the inner diameter of one side pipe. CONSTITUTION:A hole saw boring machine 1 is inserted into a branch pipe 201 from a house inlet and the like so as to bore a lining material 202 with a drill. Then, the hole saw boring machine 1 is retracted to the original position, and a saw blade boring machine is inserted into the branch pipe 201 until the stopper 89 of a stationary cylinder 85 strikes against the circumferential surface of a bored hole 203. Then, the saw blade 121 is reciprocated so as to cut the lining material 202 spirally. At this time, the reaction of cutting is caught because the stopper 89 is fixed on the lining material 202. The method as described above enables boring without suspending the use of sewage pipes, thereby enabling boring along side of the inner circumferential surface even in a bent pipe because the cutting is made by making use of the elasticity of the saw.

Title: Line sensor
Inventor: TSUCHIDA HIROYASU
IPC: H04N1/19
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To receive an image without color smear by selecting an interval of the same pixel lines to be a specific multiple of a vertical pixel pitch of each pixel line. SOLUTION: The line sensor 1 reads three lines, 1st, 2nd and 3rd pixel lines for the movement of one line in the vertical direction. An interval d1 of the 1st pixel lines 11 is selected to be a multiple of (an integer +1/3) of a pixel pitch p1 in the vertical direction in each of the 1st-3rd pixel lines. Thus, a position of an original corresponding to a 2nd output of the 1st-pixel line 11b is deviated from a position of the original corresponding to a 1st output of the 1st-pixel line 11b by an interval of a multiple of 1/3 of the pixel pitch P1 in the vertical direction. Since an image is picked up when it is deviated by a multiple of (an integer +1/3) of the pixel pitch p1 through sequential read of the 1st-3rd pixel lines in a conventional processing system, the line sensor 1 corrects the deviation.

A tracking-region-main-axis measuring means 10 regards the all regions corresponding to the previous target candidate region number outputted from a target-candidate selecting means 13 as one region, measures the main axis as the previous tracking region and outputs the main axis. A center-of-gravity/main axis distance measuring means 11 measures the distance between the center-of-gravity of every region and the main axis of the previous tracking region. A main-axis-slant- error measuring means 12 measures the angle between the main axis of the every region and the main axis of the previous tracking region. A target-candidate selecting means 13 outputs the region number so that the region, wherein the errors of the distance between the center of gravity and the main axis and the inclination of the main axis are within the threshold values, is made to be the target candidate.
