Title: Rotor for permanent magnet rotary machine
Inventor: SUZUKI NOBUNAO
IPC: H02K1/27
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To reduce eddy current loss of a rotor for permanent magnet rotary machine by vapor-depositing a metal having lower electrical resistivity than the material of the rotor over the entire surface of the rotor. SOLUTION: In order to reduce eddy current loss of the surface of a rotor 1, a coating film 3 having electric conductivity higher than that of the material of the rotor 1 is formed on the surface of the rotor 1. When, for example, silver which has the lowest resistivity among metals is vapor-deposited on the surface of the rotor 1, the eddy current loss caused by the untreated article existing conventionally on the surface of the rotor can be reduced by about 40%, when the thickness of the silver film is >=0.7 mm and by about 20% even if the thickness is as small as 0.3 mm.  When copper which is less expensive than silver and has resistivity nearly equal to that of silver is vapor-deposited instead of silver to reduce the economic burden, the eddy current loss can be reduced by about 40% when the thickness of the copper film is >=1 mm and by about 20%, even if the thickness is 0.5 mm, while the vapor deposition efficiency is about 95% of that of silver. In addition, when a copper alloy having a slightly larger resistivity than copper and a vapor deposition efficience which is nearly equal to that of silver is vapor-deposited, the eddy current loss can be reduced by about 40% if the thickness of the alloy is >=1 mm and by about 20% even if the thickness is 0.5 mm.

Title: Sewing machine for sewing multi-pattern
Inventor: KUNO MITSUYASU
IPC: D05B19/02
Filed: 1990-10-25
Abstract: PURPOSE:To surely form the pattern in a sewing area on cloth by displaying the maximum width in the direction orthogonal to the direction in which the patterns are arranged, at the time of combining and forming the patterns of different sizes. CONSTITUTION:When a worker operates a combination designating switch 34 in order to select a B (middle) pattern next to an A (small) pattern, a CPU 46 discriminates a fact that its switch 34 is operated, executes an increment of an address value 0001 and sets it as an address value 0002, and designates an area for storing pattern width data and pattern length data of the B (middle) pattern. When the A (small) pattern, the B (middle) pattern, the C (large) pattern, the D (middle) pattern and the E (small) pattern are combined and selected by repeating this operation, data is stored in an area designated by each address value of a RAM 54. Also, in an LCD 30, a figuration of each pattern, and a distance in the left and the right directions and the forward and the backward directions are displayed. A worker recognizes actual size of the whole selected and combined pattern by looking at the displayed value, and can execute easily positioning of working cloth to a sewing needle.

IPC: G02B6/28
Filed: 1992-10-28
Abstract: PURPOSE:To obtain a multi-funnel type splitter of high productivity, in which uniformity of a branch output is not influenced by connection accuracy of an optical fiber by positioning the curvature center of a fan-shaped slab waveguide in the substrate end, and connecting directly the slab waveguide and the optical fiber. CONSTITUTION:On a substrate 2, a fan-shaped slab waveguide 3, plural funnel waveguides 4, and an output waveguide 5 are arranged in order, and the curvature center of the fan-shaped slab waveguide 3 is positioned in the substrate end face. Also, an optical fiber 1 of an input side is connected to the substrate 2 in the curvature center of the fan-shaped slab waveguide 3. Therefore, a diffracted light 7 from the optical fiber 1 expands by diffraction in the fan- shaped slab waveguide 3, and thereafter, is photodetected without waste by plural funnel waveguides 4, and guided to the output waveguide 5. Since the diffracted light 7 is made incident directly on the slab waveguide 3, an intensity distribution does not fall into disorder, and also, at the time of connection to the optical fiber, the misalignment in the horizontal direction does not cause disorder in the intensity distribution of the diffracted light, therefore, only the alignment in the vertical direction is enough.

Inventor: OGURA MANABU
IPC: G11B21/02
Filed: 1986-12-08
Abstract: PURPOSE:To enable a high accurate positioning by forming a groove part at a 1st bearing to suppress a movement of the 1st bearing in the tangential direction against a guide rail. CONSTITUTION:The movement of a carriage 2 is prohibited in the direction of Y-axis by the 1st bearing 20 slanting each-other and is also prohibited in the direction of Z-axis by a guide plate 24 for pressing a 2nd bearing 23, so that all directional components of freedom for the carriage 2 are suppressed except the direction of X-axis. Then, even when a shaping dimensional error and a fitting dimensional error, etc., of the guide rail 5, bearing 23 and so forth arise, a pre-load against the bearing 23 becomes constant approximately due to the guide plate 24 because of its flat spring, and hence an angular moment of the carriage 2 around a center of X-axis line is prohibited from happening. In addition, even if the angular moment must happen, the guide rail 5 is brought into surface contact with the groove part 21 and then the bearing 20 is prohibited from moving in the tangential direction against the guide rail 5, so that the carriage is restrained from revolving around the center of X-axis line.
