Abstract: PURPOSE:To reduce the power loss and the variance of a load current for a partial trouble of redundant constitution by providing a current detecting circuit with the first and the second windings at least and providing a current limiting circuit connected in series to the second qinding and a resistance. CONSTITUTION:In a constant current circuit 2, a current detecting circuit 5 is provided with not only the first DC winding WD1 through which a transmission current I1 of a constant current source 3 passes but also the second DC winding WD2 through which a current I2 shunts to a resistance RP passes, and a current limiting circuit 8 is connected in series to the resistance RP for taking partial charge of a load. A control circuit 6 sends a control signal, which has a voltage proportional to the difference between a voltage Vd of the signal transmitted from the current detecting circuit and a preliminarily determined reference voltage V0 for a value I10 of the current I1, to the constant current source 3, and the current I1 is so controlled that the voltage of the control signal is zero. When several constant current circuits, for example, two equal circuits 2A and 2B are operated simultaneously, the operating point is the intersection between characteristics A0 and B0, and they share equally the load, and a current IL is IL0, and the power loss for the resistance RP and gamma is reduced. Further, the increase of the current I2 is limited by the current limiting circuit 8.

Abstract: PURPOSE: To eliminate interference in meshing of both splines by setting the tooth profiles of both splines in consideration of the inclination of a tooth of a flex spline in a relation to a circular spline. CONSTITUTION: In the tooth profiles of the meshing teeth 30, 32 of a flex spline (a flexible external gear) 26 and a circular spline (a rigid internal gear) 26, the inclination of a tooth flank in relation to the reference tooth profile is adjusted on the basis of the mapping curved line including the adjustment to the inclination 46 of the meshing teeth 30 of the flex spline 26. That is, the tooth profile curved line part corresponding to the tooth flank of the tooth top is slightly inclined inward by taking a point on a pitch circle as the center so that the tips of a pair of tooth flanks of respective teeth 30, 32 may be approached to each other at a part on the tooth top side from the pitch circle by the reference tooth profile. Therefore, interference in meshing of both splines 26, 28 can be reliably eliminated even in mesh contact in the wide range. High torsional rigidity can be obtained by allowing mesh-contact in the wide range.

Filed: 1988-06-30
Abstract: PURPOSE: To obtain a stereoscopic phase reflection hologram which has high diffraction efficiency and is easily duplicatable by exposing a recording medium with interference light beams to form laminar exposed surfaces and openings of staircase structures in the depth direction of this medium. CONSTITUTION: The recording medium 15 of a positive photoresist is subjected to two times of exposure by interference light beams. The exposure of the first time makes the object beam 40 and the reference beam 41 incident on the recording medium 15 opposite to each other from both sides of the medium, thereby forming exposure planes 20 to 23 in a laminar form in the medium. The spacings between these planes are equal to half the wavelength of the light passing the inside of the recording medium. The surface 30 of the recording medium 15 is then opened by the exposure of the second time and etching is executed to form the staircases 35 to 38 of the gratings having plural pieces of the staircase structures of a pyramid type. As a result, the stereoscopic phase reflection hologram which has the high diffraction efficiency and is easily duplicatable is obtd.

Title: Spectroscopic analysis apparatus
Inventor: MATSUZAWA OSAMU
IPC: G01N21/73
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To measure with a good stability even when a peak of any light intensity is repeatedly measured by setting a diaphragm to an optical path to prevent a detect value stability from being affected by an open time of a mechanism shutter with an exposure time being set equal and, controlling the intensity of light focused to a two-dimensional detector. SOLUTION: A sample is introduced to a light-emitting part 1, thereby emitting light. The light enters a spectroscope via a condenser lens 2, an entrance slit 3 and the like. A divergent luminous flux 5 is reflected by a collimating mirror 6 and enters a diffraction grating 7. Grooves are formed at regular intervals to a surface of the diffraction grating 7. The light hits a order dispersion element 4 and scatters after being dispersed to wavelengths. The light thus dispersed in two dimensions is turned by a camera mirror 9 to a convergent luminous flux 20, reflected and focused to each coordinate of a two-dimensional detector 8.  If a light-reducing means 11 is set in an optical path of a parallel luminous flux 14, the light passing the light-reducing means 11 is turned to the circular parallel luminous flux 14 of an equal diameter to an opening part of the means and eventually focused to one point of the two-dimensional detector 8.
