摘要： PROBLEM TO BE SOLVED: To provide a pulse wave sensor capable of reducing a noise light and having high detection probability.
SOLUTION: This reflection type pulse wave sensor having a light emitting element 3 and a light receiving element 4 is disposed with a light control film 10 on the upper part of the light receiving element 4. This constitution can cut off disturbance light whose incident angle is a prescribed value (for example 35°) or more so as to reduce false detection due to the effect of the disturbance light and improve the detection probability.

摘要： PROBLEM TO BE SOLVED: To provide a pulse wave sensor capable of reducing noise light and enhancing detection probability. SOLUTION: For this pulse wave sensor 1, a light shielding member 6 is arranged between a light emitting element 3 and a light receiving element 4 housed in a package 2. Sometimes a part of light irradiated from the light emitting element 3 is reflected on the boundary of the surface of a light transmitting plate 5 and the skin surface of a finger F and returns to the light transmitting plate 5. For that, since the light shielding member 6 is arranged between the light emitting element 3 and the light receiving element 4 for the pulse wave sensor 1, the light reflected on the boundary among the light irradiated from the light emitting element 3 is blocked from entering the side of the light receiving element 4 from the light shielding member 6. As a result, the light reflected on the boundary is not directly made incident on the light receiving element 4 and the influence of reflected light is eliminated in the measurement of pulse waves.

摘要： PROBLEM TO BE SOLVED: To provide an optical scanner which can be made compact and which is constituted so that an optical scanning action can be excellently executed by accurately controlling the deflection angle of a light beam. SOLUTION: This optical scanner is constituted so that an angle detection signal is generated by an optical sensor disposed in front of a deflecting mirror M or a position sensor, an angle sensor and the like attached to the mirror M when the deflection angle of the light beam arrives at a prescribed angle by the vibration or the rotation of the mirror M. By a minute angle signal generation part 10, a minute angle signal is generated by multiplying a reference signal based on the reference signal synchronized with the vibration or the rotating cycle of the mirror M generated according to the angle detection signal. By a deflection angle interpolation signal generation part 12, the minute angle signal and an angle signal showing the specified deflecting angle of the light beam are inputted and a deflection angle interpolation signal for interpolating an interval between the angle detection signals is generated as the light emission timing signal of a light source.

摘要： PROBLEM TO BE SOLVED: To provide a process for producing a high polymer dispersed liquid crystal panel which is low in driving voltage and is high in display contrast. SOLUTION: This high polymer dispersed liquid crystal panel is produced by forming the panel as a high polymer dispersed liquid crystal layer 90 obtd. by interposing a liquid mixture composed of an unpolymerized photosetting resin and liquid crystals between both electrodes substrates 70 and 80, irradiating this liquid mixture with light to polymerize the photosetting resin and to fix the phase sepn. of the liquid crystals and the resin, thereby holding and dispersing the liquid crystals into the resin matrix. Such UV rays (UV rays of the wavelength longer than 320nm) of the prescribed wavelength range which improve the display contrast of the liquid crystal panel and lower the operation voltage of the liquid crystal panel are used as the light for irradiation to the liquid mixture.

摘要： PROBLEM TO BE SOLVED: To drive the vibration system of a resonance type optical scanner device always at a resonance frequency and obtain always a stable scanning angle. SOLUTION: A reflecting mirror 5 is supported by the vibration system which can cause torsional vibration around a specific axis and vibrated through piezoelectric bimorphs 6 and 7 and the vibration is detected by piezoelectric unimorphs 8 and 9. A driving circuit 40 inputs detection signals from the piezoelectric unimorphs 8 and 9 to a self-oscillation circuit consisting of a phase shifter 50 and a low-pass filter 51 to generate a control signal to be fed back to the piezoelectric unimorphs 6 and 7 positively, and a control circuit consisting of a rectifying circuit 44, a smoothing circuit 45, and a differential amplifier 46 generates a control signal for making the amplitudes of the detection signals constant, and those control signals are multiplied by a multiplier 54 to generate a driving signal, thereby driving the piezoelectric unimorphs 6 and 7. Consequently, the reflecting mirror 5 can be driven always at a constant scanning speed without being affected by temperature, pressure, etc.

摘要： PROBLEM TO BE SOLVED: To make the scanning angle of an optical scanner device, which makes an optical scan by turning a reflecting mirror in the one-dimentional direction, without increasing the size of the device. SOLUTION: On both sides of a mirror part 33 where the reflecting mirror is formed, spring parts 35 and 37 are formed directly and formed into a rectangular wave shape, and piezoelectric elements are adhered to mount parts 47 and 46 connecting the spring part 35 and an external frame 31 to form a piezoelectric unimorph for driving, thereby constituting an optical deflecting element for optical scanning. Consequently, the reflecting mirror and a coil for vibration generation need not be supported by the spring parts 35 and 37 unlike a conventional device, and the spring parts 35 and 37 can be made small. Further, since the spring parts 35 and 37 are formed into a rectangular-wave shape, the spring parts 35 and 37 can be shortened in overall length while their substantial lengths are maintained. Therefore, while the scanning angle is secured, the deflecting element, and then the optical scanner device, can be made small-sized.

摘要： PROBLEM TO BE SOLVED: To sufficiently shorten a focal position in the constitution using a variable focus lens and adjusting the focal position. SOLUTION: A variable focus lens part 13 is constituted of the variable focus lens 14 and a fixed objective lens 15. The variable focus lens 14 is constituted so that a piezoelectric element 26 is film formed on a glass diaphragm 25, and silicon oil 28 is sealed in the inside. Then, the curvature of the glass diaphragm 25 is changed by driving the piezoelectric element 26, and the focal position of the variable focus lens part 13 is changed. In such a case, laser light from a semiconductor laser is made incident on the variable focus lens 14 in the state converged by being made incident on the fixed objective lens 15. Thus, the focal distance of the variable focus lens part 13 is shortened.

摘要： PROBLEM TO BE SOLVED: To provide an optical scanning device having a low parts count, a stable beam form, and a large deflection angle obtainable, and permitting to reduce a physical size and weight. SOLUTION: A refracting interface 6b is a hemispheric surface, and forms a rotation symmetry about two rotation axes A1 and A2 as symmetrical axes. Even if reflected light Lo is directed in any direction by rotating a lens member 6, laser light Li is made incident on the lens member 6 always in a fixed state. Further, since an angle of refracting interface 6b to the reflected light Lo is also constant, the laser light exits from the lens member 6 to outside always in a fixed state. Therefore, a shape of the laser light becomes stable even if it is scanned in any direction, and detection accuracy is stabilized and high precision can be maintained. Further, since incident and exit directions of the laser light allow this device to disregard location of other optical, elements, a large deflection angle is obtained, and a low parts count is required for this device.
