Patent JP-S56122925-A (JP)
Title: Sensor
Inventor: SHIMADA YOSHIO
IPC: G01L9/00
Filed: 1980-02-29
Abstract: PURPOSE:To obtain a sensor which can convert the change of a physical quantity to an intermittent output change, by irradiating the light to the mirror surface of the elastic member excited by the exciting mechanism and by detecting the output change of the reflected light optically. CONSTITUTION:Pressure receiving diaphragm 1 is provided which forms one face of pressure leading-in room 2 and has one face subjected to the mirror face 1a treatment. This pressure receiving diaphragm is excited by oscillating coil 3, and excitation is detected by pickup coil 4 and is fed back to control part 5 of oscillating coil 3 to generate a natural oscillation corresponding to the sag quantity of diaphragm 1. For the purpose of detecting this natural oscillation, if fibers are so arranged that the light incident to incident light fiber 6 is reflected by mirror face 1a and is outputted to emitted light fiber 7 under the state where diaphragm 1 is not sagged, the incident light is taken out twice from fiber 7 at one period when diaphragm 1 oscillates at a fixed period, and thus, the sag quantity is converted to a light signal.

Title: Light control method and light controller
Inventor: KASAI TOSHIKI
IPC: G02F1/01
Filed: 1996-02-14
Abstract: PURPOSE: To provide a light control method which draws the light response of a sufficient size and velocity out of a light responsive optical element with the lowest possible light power and a light controller. CONSTITUTION: The control light is emitted from a light source l and the signal light from a light source 2. The control light and signal light are converged by a condenser lens 7 and are cast to the optical element 8. Only the signal light is detected by a photodetector 22 through a photodetecting lens 9 and a waveguide selective transmittable filter 20. The transmittance of the signal light is reversibly increased and decreased by the on and off of the control light, by which the intensity modulation of the signal light is embodied. The interaction effect of the excitation species in the light responsive compsn, the control light and the photon of the signal light is greatly improved by converging the control light and the signal light and propagating the light on the same optical path. The drawing of the light response of the sufficient magnitude and velocity out of the light responsive optical element with the light power sufficiently lower than heretofore is made possible.

Title: Motor driving mechanism of lens
Inventor: WATANABE KENJI
IPC: G02B9/08
Filed: 1985-02-14
Abstract: PURPOSE:To reduce a projecting part of a motor driving device of a lens, to make the device small-sized and to reduce a required working precision by pulling a wire, whose both ends are fixed to a helicoid ring, to turn the helicoid ring. CONSTITUTION:When a driving motor 19 is driven, a take-up drum 18 is turned, and a wire 13 wound around the take-up drum 18 is moved in accordance with the turning. Since one end of the wire 13 whose both ends are fixed to a helicoid ring 11 is pulled, the helicoid ring 11 is turned in the pulling direction, and the other end is moved in accordance with this turning. the helicoid ring 11 is moved forward or backward in the direction of the optical axis in accordance with turning. Since the angle of inclination of a wire groove 12 coincides with the lead angle of a helicoid 17, the helicoid ring 11 is turned smoothly throughout the moving area. Thus, the device is made small-sized, and the working precision is reduced.
