Abstract: PROBLEM TO BE SOLVED: To ensure sealing performance by a sealing plate, by providing a curved surface part for connecting the end parts of both the side surfaces and the end part of a bottom surface in a sealing groove, to slidingly contact the end part of an elastic material to the curved surface part. SOLUTION: A bottom surface 14 and respective side surfaces 15 and 16 are continued in the tangent direction of respective curved surface part 17 and 18 from both the end parts of them. The inner peripheral end edge of an elastic material 12 is slidingly contacted with the curved surface part 17 existing near to the axis direction center of an inner wheel 2. Moreover, a position, with which the inner peripheral end edge is slidingly contacting, is preferably the center part of the curved surface part 17 as much as possible. The dimensional error and an assembling error, etc., of a constituting member are regulated, so that, the inner peripheral end edge can not be uncontacted from the curved surface part 17, despite an unavoidable dimensional error, etc.  Consequently, in a roller bearing with a sealing plate, abutting pressure between the inner peripheral end edge of the elastic material 12 and the curved surface part 17 can be ensured, to ensure sealing performance by a sealing plate 5, even under a severe condition like at the time of high-speed operation.

Title: Three-dimensional shape measuring apparatus
Inventor: INOUE KIYOSHI
IPC: G01C3/06
Filed: 1992-01-31
Abstract: PURPOSE:To reduce the errors caused by the inclination of a surface to be measured and the like and to make it possible to perform precise measurement by providing an apparatus, which uses the position of a light spot that is discriminated with an optical position detector as the data and operates a three- dimensional-shape signal. CONSTITUTION:The reflected light from the slant surface of a material to be measures repeats the reflection at the other surface. The diameter of a light spot, which is cast into an optical position detector CCD 3 becomes a<b<c. The shapes of the reflected spots from the vertical surface become approximately equal. The secondary reflected light has the long elliptical shape, and the spot diameter is increased. In an operating device, a discriminating- reference value for the spot shape to be detected is inputted as the value of (a) or less. The values (b) and (c) are removed from the data. Thus, the reflected light from the slant surface is removed, and the data are processed. In this way, the three-dimensional signal is operated based on only the detected data when the light is cast on the surface to be measured approximately vertically by the discrimination of the detected signal. Therefore, the shape can be measured in extremely high accuracy.

Title: Multiple wavelength spectroscope device
Inventor: SONOBE SHIGERU
IPC: G01J3/20
Filed: 1982-04-14
Abstract: PURPOSE:To enhance light measuring accuracy by a simple improvement, by providing a light shielding plate, which shields the straight input of dispersed light, for at least one light receiving element in an image forming region of the dispersed light, detecting the amount of stray light, and correcting the amount of the stray light with respect to the measured values of the light from other light emitting elements. CONSTITUTION:The light, which is inputted to an incident slit 1 from a light source, is dispersed on a photodiode array 4 and an image is formed. The photodiode array 4 is arranged on a Rowland circle, and the light is dispersed sequentially from a short wavelength side between l0 and ln. When diffracted light in the range of l1-ln is inputted to the photodiode array 4, the light is reflected and scattered on the surface of each of photodiodes 61-6n. The light is further reflected by a light receiving window 7 and inputted again. At this time, the scattered and astrayed light is distributed to the photodiode 60 on the short wavelength side, and the largest effect is received. Since the direct propgressing light is not inputted to the photodiode 60, only the astray light is detected. The same amount of the astray light is inputted to the neighboring photodiode 6a. When the detected astray signal of the photodiode 60 is subtracted from the detected signal of the photodiode 6a, the effect of the astray light of the photodiode 6a is mostly eliminated.

Abstract: PROBLEM TO BE SOLVED: To provide an orthogonal modulator that applies orthogonal modulation to a modulation signal on which a subcarrier is multiplexed such as a signal used in an orthogonal frequency division multiplex method and to provide an orthogonal modulation method. SOLUTION: A serial-parallel converter 101 converts a modulation symbol serial signal applied to an input terminal 100 and representing a complex number into a parallel signal, which is fed to complex conjugate arithmetic units 102-1-102-K and an inverse Fourier transform device 103. Each of the complex conjugate arithmetic units 102-1-102-K generates a modulation symbol denoting a conjugate complex number of a value represented by each modulation symbol and gives the generated modulation symbol to the inverse Fourier transform device 103. The inverse Fourier transform device 103 applies inverse Fourier transform to the values each denoting the modulation symbol received by itself.  The inverse Fourier transform device 103 applies inverse Fourier transform to the values each denoting the modulation symbol received by itself, modulates a plurality of sub-carriers by using the modulation symbols to generate digital signals denoting frequency multiplexed orthogonal modulation waves. A parallel-serial converter 104 converts the digital signals generated by the inverse Fourier transform device 103 into serial signals, which are outputted from an output terminal 105.

Title: Dual-stage automotive airbag inflator
Inventor: DONARUDO JIEI PATSUKUSUTON
IPC: B60R21/26
Filed: 1991-03-26
Abstract: PURPOSE: To provide a dual-stage airbag inflator which has two compartments of different size and is operable initially, when activated, to cause an airbag to deploy slowly and then, after a predetermined delay, to deploy rapidly. CONSTITUTION: Gas generant charge is ignited in a first compartment 32 which is smaller since it is to produce a smaller amount of gas to cause the initial slow deployment of an airbag and, after a predetermined delay, gas generant charge in a second compartment 34 is ignited. The delay is produced by an initiator 30 including a squib 70 and a fuse cord 46. The fuse cord 46 passes through a bulkhead and ignites all igniter materials in both the compartments simultaneously. The igniter material in the first compartment 32 burns outwardly rapidly while that in the second compartment 34 burns outwardly relatively slower. As a result, the gas generant in the first compartment 32 is ignited before the gas generant in the second compartment 34.  The burn rate of the igniter material in the second compartment 34 may be made slower than that in the first compartment 32 by using igniter materials of different chemical composition or by increasing the size of the igniter material, giving it a greater burn area, thus causing it to be consumed slower.
