Title: Rotor stop position detector for dc brushless motor having no position detector
Inventor: UEKI YASUHIRO
IPC: H02P6/06
Filed: 1990-08-18
Abstract: PURPOSE:To make possible positional measurement without requiring special AD converter by detecting relative position between the pole of rotor and three- phase winding based on a time value measured individually for each conduction pattern. CONSTITUTION:Inductance of each winding varies according to the combination mode of the type of conduction pattern and six types of conduction modes for performing 120 deg. conduction with respect to windings U, V, W. Consequently, 120 deg. conduction is effected sequentially for the three-phase windings U, V, W according to the six types of conduction patterns. States of voltages at six neutral points under transient state, which are measured individually at a neutral point Pcom, are judged according to a discharge curve obtained by discharging a nonconducting coil stored with energy during previous time conduction. Consequently, relative position between the magnetic pole magnetized by a rotor 30 in standstill state and the three-phase windings U, V, W can be known.

Title: Back projection screen
Inventor: YOHANESU KORUNERISU FUAN DE FU
IPC: G03B21/62
Filed: 1990-08-21
Abstract: PURPOSE: To provide a back projection screen which has a wide surface area and eliminates practically obvious color slurring by providing a 2nd light diffusing element on the back side of a plate. CONSTITUTION: This screen has two plates. A back plate 31 has a Fresnel structure so that the pupil of a projection lens system can be imaged inside an audio-visual space, and a front plate 40 has an element 41 on the front side so as to diffuse light within a horizontal plane. These elements 41 are extended over the height of the screen. These elements 41 having recessed apex parts have extremely satisfactory characteristics concerning the diffusion of light in horizontal direction and the color slurring within this plane. The diffusion of light perpendicular, namely, vertical to the surface of paper is caused by a lot of transparent particles 42 of which the refraction factor is away from that of materials of the plates. Thus, the screen having the wide surface area and eliminating the practically obvious color slurring can be provided.

Title: Mozaic information system for color picture
Inventor: KANAMORI TORU
IPC: H04N7/173
Filed: 1986-09-17
Abstract: PURPOSE:To match the system accurately with the substantial color boundary by decreasing the degree of contribution to the mozaic pattern conversion for color components other than a selected color so as to make the effect of shape change due to the selection of a prescribed number of colors hardly take place after the selection of the prescribed number of colors constituting mozaic patterns among colors included in a mozaic area. CONSTITUTION:The degree of contribution to the conversion of a mozaic pattern 11 is decreased or disregarded for colors 10A other than the selected colors in each mozaic area 10. For example, an original picture shown in figure (a) is 35% white, 45% black and 20% red. Then a red picture is changed into an approximated white picture element, but distinguished from the substantial white picture element, collated with the mozaic pattern, and the degree of coincidence of collation is given a low mark or disregarded entirely. Thus, the mark of the degree of coincidence for the collation of the mozaic pattern as shown in figure (b) is decreased and the degree of coincidence for the collation of the mozaic pattern (c) closer to the original picture image is increased. As a result, high similarity is given to a pattern with much more fidelity with the original picture as the mozaic pattern is increased and selected.

Title: Chucking device for balance test machine
Inventor: FUJIE MASANORI
IPC: G01N3/04
Filed: 1985-09-30
Abstract: PURPOSE:To eliminate the eccentricity of work and to improve measuring accuracy by engaging a flexible chucking member and a rigid chucking member with a pushing rod. CONSTITUTION:When a work W is fitted and a pushing rod 1 is advanced, the first taper surface 7 of a head 2 pressures the first inclining surface 18 of three flexible chucking members 14...14, deforms an elastic deforming part 16 and holds the first cylinder inner surface B of the work W at the prescribed position. Almost simultaneously, the second taper surface 11 of a pushing sleeve 9 pressures the second inclining surface 23 of three rigid chucking members 15...15 and the second matching surface 24 pressures the second cylinder inner surface C. At such a time, since for the rigid chucking members 15...15, the force is operated through a belleville spring 10, for the holding position of the work W, the position regulation by elastic chucking members 14...14 takes priority. Whereas, since the friction coefficient of the second matching surface 24 of the rigid chucking member 15 is larger than that of the first matching surface, the torque transfer by the rigid chucking members 15...15 comes to be main.
