Title: Detector for out of focus
Inventor: AOI SHIGERU
IPC: G11B7/09
Filed: 1982-09-21
Abstract: PURPOSE:To enable the sure detection for out of focus by making the size of the photodetecting elements of the two photodetectors disposed respectively at an equal space before and behind the focus of a light beam equal to the range of the light projected to the incident face of the photodetectors when the focus is matched. CONSTITUTION:The reflected light from a recording medium is focused by an objective lens and a spherical lens 12 onto the focus 14 on the optical axis 13. Photodetectors 100, 101 are disposed at an equal spacing before and behind the focus 14. The beam at roughtly the upper half part 17 of the optical axis 13 among the beams past the spherical lens 12 is detected with a photodetector 100 and does not advance beyond the same. On the other hand, the beam at the lower part 18 which is not blocked by the photodetector 100 among the beams past the lens 12 passes the focus 14 and is detected by a posterior photodetector 101. The output signals of the photodetectors 100, 101 are inputted to a differential amplifier, where the levels of both are compared and the out of focus signal is outputted.

Title: Inductance part
Inventor: HANDA HIROYUKI
IPC: H01F30/00
Filed: 1990-06-21
Abstract: PURPOSE:To reduce loss in an inductance part by preparing gaps between the central magnetic leg of an E-shaped core, outer magnetic legs of the core, and bar type cores placed between the three magnetic legs so made as to have a structure which hardly generates eddy current. CONSTITUTION:Since between the central magnetic leg 5, outer magnetic legs 6, and bar type cores 2 gaps 4 are made, the gap size does not cause the height of an inductance part to change. Further, fluxes 7 that are generated in gaps 4 traverse the flat part of a conductive member 8 formed into a printed coil 3 at an angle close to the parallel direction, and further since multistage gaps are prepared, the structure of the inductance part is so made that it hardly generates eddy current and provides the effect of reducing the loss in the inductance part.

Title: Marker eliminating device
Inventor: KOMATSU YASUO
IPC: H04N1/38
Filed: 1990-06-21
Abstract: PURPOSE:To obtain a binarized picture signal with high quality by applying processing of eliminating a picture input signal on a marker when its level is lower than an upper limit of a gray level of the marker and applying processing of not eliminating the picture input signal when the level is higher than the upper limit. CONSTITUTION:A marker elimination device consists of an area recognition circuit 1, a comparator 2, a NAND gate 3 and an AND gate 4, and the comparator 5 forms a binarizing circuit converting a multivalue output into a binary output. Then a picture input signal is eliminated when the picture input signal is on a marker and the level of the picture input signal is lower than the upper limit of a gray level of the marker and the picture input signal is not eliminated when the picture input signal is higher than the upper limit. As a result, a white level picture output signal is obtained where the marker is not formed, e.g. on character information, and character information is obtained where the marker and the character information are overlapped. Thus, a binarized picture signal with high quality is obtained.

Title: Pattern gap calculator
Inventor: TAKENAKA SHIRO
IPC: H05K3/00
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To speedily secure a minimum gap through a little processes by classifying the form of arrangement between a pair of line patterns into parallel relationship, fan-shaped relation or zigzag relationship and respectively calculating the minimum gap between these respective line patterns through 1st, 2nd and 3rd arithmetic means. SOLUTION: In the respective line patterns, straight lines L1 and L2 are generated by extending center line segments AB and CD of these patterns. When the straight lines L1 and L2 are parallel, the 1st arithmetic means calculates a minimum gap G between the line patterns by discriminating whether the line segments AB and CD are mutually overlapped or not. When the straight lines L1 and L2 are fan-shaped, the 2nd arithmetic means finds the absolute value of shorter distance between the end points of the line segments AB and CD and defines a value subtracting double edge width (d) from that value as the minimum gap G. Further, when the straight lines L1 and L2 are zigzag- positioned, the 3rd arithmetic means finds the absolute value of a distance between the closest end points and defines a value subtracting the double edge width (d) from that absolute value as the minimum gap G.

Filed: 1989-06-27
Abstract: PURPOSE:To improve the weldability of an electrical steel sheet as well as the suitability to blanking by forming org. insulating coating films different in thickness on the front and rear sides of the steel sheet. CONSTITUTION:Org. insulating coating films or org.-inorg. mixed insulating coating films are formed on both sides of an electric steel sheet so that the film on the front side is made thicker than the film on the rear side.

Abstract: PURPOSE:To evaluate a risk accurately by precisely specifying an object to be measured under various working environment. CONSTITUTION:Relative ratios among the output levels of reflected light from objects to be measured at a time when the objects to be measured are irradiated with light having different wavelength from three semiconductor lasers 1a, 1b, 1c of a light source section 1 and relative ratios among the output levels of reflected light as reference values previously stored at every kind of the objects to be measured in a measured-object characteristic storage section 12 are compared.
