Title: Farady rotator type variable power distributor
Inventor: KAGOSHIMA KENICHI
IPC: H01P1/175
Filed: 1984-09-03
Abstract: PURPOSE:To reduce the frequency dependency of a Farady rotary angle by replacing a rod ferrimagnetic body into a conductor rod loading cylindrical ferrimagnetic body. CONSTITUTION:The rod ferrimagnetic body 5 is replaced into the cylindrical ferrimagnetic body 12 loaded with a conductor rod 11. Through the structure above, an electromagnetic field is concentrated in the cylindrical ferrimagnetic body 12 between a conductor rod 11 and a tip of a ridge 5. Thus, the cut-off frequency is decreased and the change in lambda/lambdag (ratio of a free space wavelength to a guide wavelength) due to frequency is smaller than that of a conventional case without conductor rod loading. Thus, the frequency dependency of the Farady rotary angle is reduced.

Title: Object lens for scan electron microscope
Inventor: TAMURA NOBUAKI
IPC: H01J37/141
Filed: 1982-10-20
Abstract: PURPOSE:To improve the secondary electron detection efficiency by fitting an air-core coil generating a magnetic field nearly offsetting the magnetic field leaking downward from a magnetic pole hole to a lower magnetic pole. CONSTITUTION:A thin air-core coil 9 is fitted symmetrically to the axis at the lower side of a lower magnetic pole 2 so as to generate a magnetic field offsetting the magnetic field leaked from the lower magnetic pole 2. This magnetic field (a) is generated in the opposite direction to a lens magnetic field and has a magnetic field distribution as shown in the diagram. According to this reverse magnetic field, the lens magnetic field with an original distribution as shown by a dotted line is corrected as shown by a solid line (b) and is barely generated under the lower magnetic pole 2. Since the air-core coil 9 is in contact with the lower magnetic pole 2 on one side, its magnetic resistance becomes one half of that when placed in a free space, thereby the strength of the generated magnetic field is doubled with the same exciting current. Accordingly, the secondary electron detection efficiency is improved, and the secondary electron sample with high resolution can be observed.

Title: Frame structure of bicycle
Inventor: ADACHI EIJI
IPC: B62K11/04
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a frame structure capable of considerably reducing the forging cost and the welding cost in welding a front frame and a down tube by manufacturing a head pipe by a casting method. SOLUTION: A down tube is welded to an upper tongue piece 56, a lower side of a lower flange part 52, and a lower tongue piece 57. The sufficiently large welding length can be ensured as illustrated in a welding bead 66. Since the upper and lower tongue pieces are only integratedly formed with a forging, it is unnecessary to form the undercut in a forging process. Thus, the forging cost can be reduced.

In addition, the sectional area of the runner part 28 is specified to the value obtd. after the sectional area of the plunger tip 70 is divided by the feeding pressure and casting pressure or below. The back flow of the molten metal at the time of feeding does not, therefore, act on the end face of the plunger tip and is limited to the sectional area of the runner part. The feeding effect is thus surely obtd. and the product having no blowholes is obtd.

Filed: 1987-07-24
Abstract: PURPOSE:To obtain a substrate holding mechanism enabling the production of an unscratched magneto-optical recording medium on a discoid substrate or a thin film, by providing an angle to each contact part between the periphery of the substrate and a substrate fitting jig.

Title: Optical beam scanner
Inventor: HISADA TAKAKI
IPC: G02B26/12
Filed: 1988-07-26
Abstract: PURPOSE:To allow dealing with a large polarization angle and high resolution by constituting the scanner in such a manner that the radii of curvature of the cylindrical faces of a lens group constituting an optical system for focusing a deflected light beam onto an object to be scanned so as to satisfy specific conditions. CONSTITUTION:The optical system between a rotary polyhedral mirror 8 of the optical beam scanner and the object 9 to be scanned consists of a lens 1, one face of which is a cylindrical face 1a and the other a spherical face, a lens 2 one face of which is a cylindrical face 2a and the other a plane 2b, and a lens 3 one face of which is a plane 3a and the other is a troidal face 3b. The curvature of field in the sub-scanning direction is well corrected by decreasing the value of R3 and increasing the value of R4 if the radius of curvature of the face 1a is designated as R3 and the radius of curvature of the face 2a as R4. The correction effect is remarkable particularly under the condition under which the relation of R3 and R4 attains (1/R3)>(1/R4). The curvatured of field in the sub-scanning direction is thus confined practicably within the range where there are substantially no problems.
