In addition, focusing may be executed. The light 60 from an object side is refracted by the faces R1, R2 of the free curvilinear face prism 51, is reflected by the reflection mirror (thin film), 53, is reflected by the face R3 of the free curvilinear face prism 51, is refracted by the face R4 and is then made incident on a solid-state image pickup element 55. The device constitutes the image pickup optical system by the free curvilinear faces R1 to R4 and the reflection mirror 53 in the manner described above.  The aberrations of the object image are minimized by optimizing the shapes of these free curvilinear faces R1 to R4.

Title: Iron core movable type linear oscillator and linear compressor
Inventor: INOUE MASAYA
IPC: F04B35/04
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To attain a highly efficient oscillator with small coil inductance by fitting at least one set of permanent magnets with the one that has the same polarizing direction as the magnetic flux direction of the coil, and the one that has the opposite polarizing direction facing the air-gap in the magnetic flux magnetic circuit of a stator iron core coil taken as one set. SOLUTION: Permanent magnets 3a, 3b are polarized respectively in the +x or *direction of a coordinate axis. The permanent magnets 3a, 3b are constituted of permanent magnets formed integrally or by disposing two or more segment magnets with a different polarizing direction. The polarizing direction of the permanent magnets 3a, 3b at the upper and lower parts of a coil 1 is the same as the generated field direction of the coil 1, therefore, the permanent magnets 3a, 3b at the upper and lower parts of the coil 1 are magnetized, and the polarizing direction of the permanent magnets 3a, 3b at the upper and lower parts of the coil 1 is different from the generated field direction of the coil 1, so that the permanent magnets 3a, 3b at the upper and lower parts of the coil 1 are demagnetized.  It is thus possible to move a movable iron core 12 to a position, where the magnetic circuit of a composite magnetic field is formed, and generate thrust.

IPC: B23F5/08
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To enable generating and grinding for a gear on a forming grinder by fitting a grinding wheel to the lower end of a grinding wheel spindle of the molding grinder, and generating and grinding a gear in combination of dividing rotation of a dividing head, the feed operation of a Z-axis table of a gear to be ground and the operation of moving in the direction of Y-axis of the grinding wheel. SOLUTION: In generating and grinding a gear with a forming grinder, the operation similar to the movement of a rack and a gear is performed by the movement in the direction of Y-axis of a rack-shaped grinding wheel mounted on the lower end of the grinding wheel shaft, and the dividing rotation of a gear by a dividing head 13. It is sufficient to move a Z-axis table 20 in the direction of a Z-axis for movement in the direction of face width. At this time, if the Z-axis table 20 is moved while Y-axis is moved, the quite same movement as that of a helical gear can be done. In the case of the helical gear, when Y-axis is fixed, and Z-table 20 and C-axis of the dividing head 13 are moved, even the helical gear can be ground with the same number of times as that of a spur gear unlike the conventional grinder. Accordingly, generating and grinding can be done more efficiently than before.
