Title: Calibration method for stereoscopic image sensor and device therefor
Inventor: HARADA TAKASHI
IPC: G01B11/00
Filed: 1994-06-29
Abstract: PURPOSE:To provide a calibration method for a stereoscopic image sensor and a calibration device capable of calibrating the real camera system where the right and left lines of sight do not intersect each other in a strict sense. CONSTITUTION:A stereoscopic image sensor is modelled, by use of a pseudo- inverse matrix at a step S1, with the midpoint of normals drawn to the right and left sight lines of a stereoscopic camera taken as the approximate solution of least squares, and this model data is partially differentiated at a step S2, using a camera parameter as a conversion factor between the coordinate system of three-dimensional space and the coordinate system of stereoscopic camera screen. Then, the known position of a measurement object in the three- dimensional space is measured with the stereoscopic camera at a step S4. In this case, constitution is so made that the camera parameter is derived at a step S5 for minimizing a norm between both data, using the above-mentioned measurement data and the differentiated value of the model data.

Title: X-y table
Inventor: ONO HIROO
IPC: H01L21/66
Filed: 1988-06-15
Abstract: PURPOSE:To enable inexpensive and simple assembly eliminating uselessly excessive machining accuracy and adjustment by a method wherein planar bearings are arranged at three points not on a straight line and a spherical body is interposed between the bearing and an X-Y stage. CONSTITUTION:An X-Y stage 2 is supported on a stage base 1 with a flat shaft 3 with low friction resistance between the base 1 and bearings 3. A ball 4 is interposed between the bearings 3 and the stage 2 to be kept from contacting with a groove 2a of the stage 2 in plane so that the stage 2 is supported with a freedom in a direction of rotation. Thus, the stage 2 is supported in such a manner that the stage 2 is turned to be tilted through the ball 4 according to a difference in the height of the bearings regardless of variations therein. Moreover, as the stage is supported at three points, the stage 2 can be supported accurately in contact overcoming any fine tilt thereby always securing a stable support.

Abstract: PURPOSE:To increase the number of elements which can be integrated per a semiconductor chip area by assigning an active element, passive element, and function circuit using them, on the facing two sides of semiconductor crystal. CONSTITUTION:On each surface of a thin plate crystal 1 consisting of active layers 1A and 1B and an insulation intermediate layer 1M, FETs 5A and 5B consisting of sources 2A and 2B, drains 3A and 3B, and gates 4A and 4B are formed.

As function circuits are assigned on two flat sides for connection, wiring distance can be shortened, so the circuit of higher performance is realized. And, with a structure wherein devices are assigned on two flat sides, composite of different devices, which has been heretofore difficult in manufacture because of high step, is made possible.

Filed: 1986-06-24
Abstract: PURPOSE:To form the developed image of high image density by napping a magnetic brush in the first half of a developing area and preventing napping in a second half on a sleeve that supplies toner particles to a photosensitive drum. CONSTITUTION:A magnetic pole (S pole) is disposed at the upstream side in the direction of the arrow mark (b) from the closest part (g) of a developing sleeve 22 and a photosensitive drum 1. Thereby, developer carried to a developing area forms a magnetic brush in the state standing up on the sleeve 22 before arriving at the closest part (g) and is brought into contact with the drum 1. Accordingly, magnetic particles 27 or toner 28 on the sleeve 1 is released before arriving at the closest part (g). Thereby, toner 28 stuck on the surface of particles 27 can be supplied to the drum 1 without being hindered by nap 51 of the magnetic brush. Therefore, it is necessary to nap in the first half of the developing area and to prevent napping in the second half of the area. When angle made by the closest part (g) and the magnetic pole 23b is theta1, and angle made by (g) and a magnetic pole 23c (N pole) is theta2, above-mentioned setting can be satisfied by making theta1<theta2.

Abstract: PURPOSE:To prevent the inappropriate operation of a clause re-segmenting learning function performed by applying the clause re-segmenting learning function only when reading that coincides with each other exists in an input KANA (Japanese syllabary) character string. CONSTITUTION:It is judged whether or not the reading coinciding with that of data being registered on a clause re-segmenting learning dictionary 8 exists in a KANA character string from an input part 1 with a reference part 6. When the reading coinciding with that of the data being registered on the clause re-segmenting learning dictionary 8 exists in the input KANA character string, it is judged whether or not a block used in automatic blocking for KANA/ KANJI (Chinese character) conversion is included in a range where the reading coincides with each other with a control part 5. When the block used in the automatic blocking for the KANA/KANJI conversion is included in the range where the reading coincides with other, the clause re-segmenting learning function using the dictionary 8 is applied.
