Title: Bearing for high speed rotating machine
Inventor: KAMIYOSHI HIROSHI
IPC: F16C27/06
Filed: 1986-12-25
Abstract: PURPOSE:To prevent unstable vibration by arranging a magnet on the upper side of a bearing so that the bearing may support most of rotor weight. CONSTITUTION:A bearing 2 which supports a rotor 1 is a damper bearing to which springs 6 are attached. A core is arranged on the upper side of the bearing 2, and a magnet 8 is stored in it so that the bearing 2 is attracted upward by the magnetic force of the magnet 8.

Title: Optically modulating element
Inventor: ARAGAKI JIYUNKO
IPC: G02F1/1335
Filed: 1990-11-21
Abstract: PURPOSE:To obtain an optically modulating element having always stable transmission factor against temperature change by arranging a 1/2 wavelength plate between liquid crystal and an analyzer so that its optical axis direction can rotate with an optical axis of incident light toward the optically modulating element setting as the rotational center. CONSTITUTION:Incidence polarized light passed through a polarizer 1 is modulated by means of FLC layer 2, and after passing through a 1/2 wavelength plate 5, it becomes outgoing light after transmitting an analyzer 3 only in the transmitting axis direction. The FLC molecule layer 2 and its surrounding temperature detected by means of a temperature detecting unit 24 become signals to control rotation of the 1/2 wavelength plate 5 through a signal converting unit 4. Assuming now that the temperature is A deg., unpolarized incident light Ein becomes incident in the deflecting direction 45 rotated only by a cone angle thetaC of A deg. from an orientation acting axis 44 of the FLC layer 2. At this time, when electric field is not impressed upon the FLC layer 2, incident polarization rotating action does not work so that the ray of light is cut completely by means of the analyzer 3. Meanwhile, when the electric field is impressed thereupon, since a liquid crystal molecule axis turns toward 46, polarization rotating action is given by 4thetaC, so that stable transmission factor can be realized against temperature change.

A dry cell 4 supplies a current to the light emitting element. The whole of the bob is suspended with a string. Thus, the light spot is seen to surely confirm the position, and it can be confirmed even a dark place.
