Abstract: PURPOSE:To exactly read a radiograph by moving the spot projection part of excitation light circumferentially on the surface of a phosphor layer according to the rotating angle of an optical path mechanism. CONSTITUTION:The spot projection part of the excitation light 2 moves circumferentially on the surface of the phosphor layer 1b according to the rotating angle of the optical path mechanism 10 when the optical path mechanism 10 is rotated by a rotational driving mechanism 11. The spot projection part of the excitation light 2 moves on the surface of the phosphor layer 1b along the axial line direction thereof if a supporting device supporting a radiation recording member 1 is moved in an arrow (a) direction by a driving mechanism. Since the center of rotation of the optical path mechanism 10 is in alignment to the central axial line of the phosphor layer 1b, the excitation light 2 enters the phosphor layer 1b perpendicularly from the center of curvature of the phosphor layer 1b having an arc plate shape in any position on the phosphor layer 1b. The trouble of the degraded resolving power rising from the incidence of the excitation light 2 to in the part inclined to the phosphor layer 1b is thereby eliminated and the radiograph is exactly read.

IPC: D05B27/02
Filed: 1993-06-30
Abstract: PURPOSE:To accurately reciprocate a feed dog in the lateral direction by directly moving a slide alone when the feed dog is moved in the lateral direction. CONSTITUTION:When a main motor is operated, a pulley 3 fixed on a lower shaft 2 is rotated, a lever 13 is repeatedly swang corresponding to the outer circumferential shape of a circumferential face cam 4, and a feed dog 17A is repeatedly reciprocated back and forth via the swing motion of a horizontal feed member 15, so that a fabric is fed back and forth. When a step motor 18 is operated, a cross feed arm is rotated, a bend 38 of the cross feed arm is swang in the lateral direction, a slot 39 moves a pin 40 of a cross feed action member 28 in the lateral direction. Then, a slide support plate 29 connected to the cross feed action member 28 is also fed in the lateral direction, and the feed dog 17A is moved in the lateral direction together with a slide 31. As the heavy horizontal feed member 15 is not necessary to be moved when the feed dog 17A is moved in the lateral direction together with the slide 31, the inertia during the lateral movement is small enough to accurately move the feed dog 17A in the lateral direction.

Title: Method for detecting fault section of power cable
Inventor: MIURA ISAO
IPC: G01R31/08
Filed: 1987-06-30
Abstract: PURPOSE:To detect an accident section by a small number of magnetic field sensors by comparing the outputs of the plural magnetic sensors which are arranged along a cable line at intervals. CONSTITUTION:If a ground-fault accident occurs at an accident point 62, accident currents of the cable 12 and cable metallic sheath 145 in the line section A where the accident occurs are nearly equal in level, but flow in the opposite directions, so that almost no voltage is induced across an electromagnetic coil 52. In an adjacent section B, a conductor current flows in red phase and a sheath current flows in blue phase, so a voltage is induced across a magnetic field sensor 50 because of the unbalance between produced magnetic fields. Further, in a section C which is adjacent to the adjacent section, the accident current flows while being divided equally into respective phases of red, blue, and black because of the grounding line 42 of a normal conduct part 40, thereby inducing a large voltage across a magnetic field sensor 50. Therefore, voltages which are developed across electromagnetic coils 52 in the respective sections are in level relation C>B>A and the accident section can be decided from the large-small relation.

Title: Forming apparatus for image
Inventor: WATANABE KIYOSHI
IPC: G06K15/00
Filed: 1988-07-01
Abstract: PURPOSE:To enable the reduction of a memory capacity required for storage of a character pattern by decoding the pattern in accordance with a system of compression when an image of the character pattern is formed on the basis of a character code inputted by an input means. CONSTITUTION:A character information control table 20 is constituted of character codes and pattern pointers indicating address positions in a character pattern storage area 21 which correspond to the codes. In the character pattern storage area 21, there are a flag 21a showing whether the direction of compression of run-length is longitudinal or lateral for a character pattern of one run-length form, and a character pattern 21b of the run-length form. One bit is sufficient for allotment to the flag 21a, since the flag 21a needs only to show whether the direction is longitudinal or lateral. When the character pattern is compressed, the character pattern is decoded and developed in the lateral direction when the flag shows the longitudinal compression for the pattern, for instance, and it is decoded and developed in the lateral direction when the flag shows the longitudinal direction. Thereby a rotation of 90 or 270 degrees can be attained simply.
