Title: Distance measuring device
Inventor: KIKUCHI TETSUO
IPC: G01C3/00
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To perform distance measurement with high precision by precisely correcting a deviation of an optical axis. SOLUTION: The image signals in front of a vehicle outputted from a pair of left and right image pickup devices 1A and 1B are inputted to a distance calculator 3 through A/D converters 2A and 2B. With the distance calculator 3, correlation calculation is performed based on the brightness information of the left and right image, and the distance to an object is measured based on parallax found by the correlation calculation. And, with the distance calculator 3, parallax distribution of the whole screen is formed, and, with an infinite- point in the image as a reference object, and with a point whose parallax is near zero as a normal value of parallax (parallax=0), a parallax correction value (deviation of parallax) is calculated based on variation degree of parallax distribution near the normal value.  The parallax correlation correction value is used for a correction value of distance measurement. At this time, a point where parallax distribution is suddenly lowered in a range where parallax moved from a positive value to a negative value, is recognized as the parallax corresponding to the infinite-point, at this time.

Title: Liquid suction and discharge device
Inventor: UEHARA MASAFUMI
IPC: F15B15/14
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To reduce abrasion of a sealing part of a piston by laminating a plurality of sealing parts and filling liquid and a lubricant adhesive material in a clearance between opposed sealing parts. SOLUTION: A liquid suction and discharge device is so constituted that the first and the second sealing parts 3, 6 are laminated after sandwiching a doughnut spacer 5 between them. The clearance between the first sealing part 3 and the second sealing part 6 is decided more clearly by sandwiching the spacer in this way, which reduces the possibility that the both are touched and broken during operating of a piston so as to reduce air tightness with the cylinder inner face. A plurality of sealing parts are installed in the piston and liquid or a consistency material is filled, at least, in a pair of opposed sealing parts.  This constitution can facilitate the sliding of a contact part between the cylinder inside face and the sealing parts of the piston so as to reduce abrasion and provide the device with tolerance of long time operation in a case of treating liquid which highly densely contains solute easy to be deposited.
