Title: Device and method for segmenting character
Inventor: MATSUURA KAZUMI
IPC: G06K9/34
Filed: 1994-03-30
Abstract: PURPOSE:To precisely and stably segment the characters based on information on the distance between the center of each character frame and a point on a character stroke. CONSTITUTION:The distances are calculated between the center points Ra, Rb and Tc of character frames 5a, 5b and 5c and the sampling points S10, P1, P2 and E10 of a stroke 10 respectively. For instance, city block distances are used for these distances. Then a distance d0a between the center point Ra of the frame 5a and the start point S1a of the stroke 10 is calculated together with a distance d1a between the point Ra and a sampling point P1, a distance d2a between the point Ra and a sampling point P2 and a distance d3a between the point Ra and a sampling point (end point) E10 respectively. Then a character frame is calculated so that the sum of those distances (d0a+d1a+d2a+d3a) is minimized and decided as a character frame to which the stroke 10 belongs. Thus the characters can be precisely and stably segmented.

Title: Fall preventing device for balanced help lift
Inventor: ISHIOKA SHIGEO
IPC: A61G7/10
Filed: 1993-02-10
Abstract: PURPOSE:To prevent a device from falling down by the erroneous operation of a helper by almost equalizing a speed for a hanger to be moved forward and backward along a lateral pillar to a speed for the head of a fall proofing wire to be moved. CONSTITUTION:When the device is stopped, a fall preventing wire 55 is previously adjusted so as not to be slacked. When a handle pipe with flange is pushed and rotated by separating a lock stick from a lock hole, a carrier 11 is moved forward or backward and a hanger 20 is similarly moved as well. At such a time, the chain of the fall preventing wire 55 is moved but since the shape of a sprocket 27 for moving carrier is equal to that of a sprocket 28 for preventing fall, the movement of both chains is equalized. Therefore, when letting the handicapped person proceed forward by turning the handle pipe with flange, the fall preventing wire 55 is always maintained in the slack-absent state. Thus, even when inertia is acted upon the handicapped person, the handicapped person is not shaked forward, and therefore, the device can be prevented from falling down.

Title: Method and device for detecting position of magnetic field-generating body, and method for detecting underground object
Inventor: KIMURA KOICHI
IPC: G01V3/08
Filed: 1995-03-22
Abstract: PURPOSE: To accurately and simply detect a magnetic field-generating body regardless of the presence of a magnetic obstacle by detecting the center direction of the magnetic field, obtaining a cross point, judging the center axis penetration point of the magnetic field, and judging the presence of the magnetic generating body. CONSTITUTION: The directions of magnetic field vectors Va, Vb, and Vd match at a center penetration point PO. It can be estimated that the magnetic field vectors are not affected by the turbulence of magnetic field and only a remaining magnetic field vector Vc is affected by the turbulence of the magnetic field. Even if only a detector 10c of center direction of the magnetic field is affected by a magnetic obstacle, detectors 10a, 10b, and 10d in the center direction of the magnetic field in the remaining three dimensions are not affected by the magnetic obstacle, thus accurately indicating the center direction of the magnetic field. It is judged that a magnetic generating body (for example, an advancing machine) exists on a line extended in a direction for crossing a plane to be measured, namely a paper surface, from a center axis penetration point Po thus obtained.
