Title: Method for three-dimensional measurement of space magnetic field distribution
Inventor: MATSUDA JINICHI
IPC: G01R33/028
Filed: 1990-01-22
Abstract: PURPOSE:To perform measurement without allowing electron beam to impinge against a magnetic part by calculating the deflection quantity of the electron beam (EB) in a non-reversal state from the deflection quantity of the EB in a reversal state in the exciting current direction of the electronic part (MP) when the EB of magnetic field deflection impinges against the MP. CONSTITUTION:A magnetic part 1 is arranged to a space (MS) to be measured and the MS is irradiated with electron beam E in such a state that an exciting current is allowed to flow to the part 1 and the three-dimensional magnetic field distribution of the MS is measured on the basis of the deflection quantity of the beam E. When the beam E impinges against the part 1 at this time, the beam E does not reach a detector and the spot due to the beam E is not present on a frame memory. At this time, it is judged that the beam E impinges against the part 1 and the exciting current direction of the part 1 is reversed and the beam E is deflected in the reverse direction and the deflection quantity thereof is measured without allowing the beam to impinge against the part 1 and, from this deflection quantity, the deflection quantity of the beam E in such a state that the exciting current is not reversed is calculated. By this method, measuring accuracy can be enhanced without allowing the beam E to impinge against the part 1.

Title: Outboard motor
Inventor: KAWAMURA HIROSHI
IPC: F02B61/04
Filed: 1994-02-04
Abstract: PURPOSE:To feed a dry air to an exhaust passage, by making the part of an atmosphere lead-in passage between a check valve and the exhaust passage in an adiabatic structure, as well as providing the check valve which is opened only when the exhaust passage side is made in a lower pressure, in the atmosphere lead-in passage. CONSTITUTION:When the exhaust system is made in a negative pressure at the starting time or in the operating time of an outboard motor, the exhaust passage 29 of a mount case 10 is made in the negative pressure at the same time, and the inside of the secondary tube 23 is made in the negative pressure by the above negative pressure, so as to make a check valve 21 in the opened condition. The air is led in to the exhaust passage 29 through the route including a suction silencer 25 and an atmosphere lead-in passage 20 (the primary tube 22, the check valve 21, and the secondary tube 23), and when the negative pressure of the exhaust passage 29 is made in the atmospheric pressure, there is no fear of reverse flow of the water at lower side of an exhaust pipe 79. Furthermore, there is hardly a fear of water invasion to the primary tube 22. Since a heat resisting rubber having a good adiabatic property is used to the primary tube 22 and the secondary tube 23, the influence of the heat on the check valve 21 can be prevented or reduced.

Title: Method and apparatus for detecting pattern
Inventor: OSHIDA YOSHITADA
IPC: G03F9/00
Filed: 1988-01-25
Abstract: PURPOSE:To obtain a detection signal faithful to an original pattern without superposing cutoff spatial frequency, by detecting a pattern by the light transmitting through a filter whose transmissivity changes in a pattern detecting direction. CONSTITUTION:The beam emitted from a laser beam source 15 is converged to the pupil 10 of an objective lens 1 through a lens 151 and a beam splitter 11 to irradiate the object 30 to be inspected on a wafer 3. The laser beam reflected from the object 30 to be inspected is incident to an imaging apparatus 13 by a lens 1 and a relay lens 12 to form the image of the object 30 to be inspected. Herein, the lens 12 forms the image of the pupil 10 on an analogue spatial filter 14 and laser beam transmits through the region 140 of the filter 14 perfectly but does not transmit through a region 142 at all and transmissivity changes in a region 141 according to a place. By this method, it is eliminated that the beam reflected from the object 30 to be inspected is steeply cut at specific spatial frequency and the pattern image of the object 30 to be inspected detected by the apparatus 13 becomes a smooth image prevented from the superposition of a specific cut-off spatial frequency and faithful to an original pattern.

Title: Coupling mechanism for rotary body
Inventor: OKANO HIROSHI
IPC: F16D1/06
Filed: 1979-02-08
Abstract: PURPOSE: To prevent slackening due to temperature rise and facilitate assembly and disassembly by a method wherein a portion of a journal portion end face perpendicular to an axis is joined to a portion of a shaft end face also perpendicular to the axis, and the joint portion is fastened with a bolt and a nut.  
     CONSTITUTION: A screw portion 2b of a shaft 2 is inserted in the central hole 1d of a journal portion 1a, and a nut 5 is engaged with the portion 2b, a spring 6 being interposed between the nut 5 and an internal end face 1e of the portion 1a. An inside cylindrical surface 2a of the shaft 2 is snugly fitted with an outside cylindrical surface 1c of the ceramic journal 1a, and concentricity is secured so that the deviation between the two elements lies within allowable limits. An end face 2e of the shaft 2 is in close contact with a journal end face 1f. Such provision of the metal shaft 2 with a screw portion overcomes inconveniences arising from brittleness of ceramic material. Further, even when the ceramic side is heated to high temperatures, the presence of a cavity 1b reduces heat transfer to the shaft 2, increasing resistance to heat.
