Title: Display device
Inventor: HONMA SUSUMU
IPC: G03B13/24
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a display device constituted so that an irregularity of luminance is reduced and light from a light source can be efficiently utilized. SOLUTION: Since the end surface 10f of a display panel 10 is provided with a reflection member 30, illumination light emitted from the end surface 10f of the panel 10 is reflected on the reflection member 30 and returned to the inside of the panel 10. One part of the illumination light returned in such a way is diffused by a display part 10a set halfway the panel 10. That is, the panel 10 integrated in this display device is constituted so that the display part 10a is illuminated with both of the direct illumination light from the light source 20 and the illumination light returned from the reflection member 30. Thus, the illumination light from the light source 20 can be utilized without waste and the luminance of the display part 10a can be sufficiently enhanced. Besides, the irregularity of the luminance can be reduced when the display part 10a is illuminated.

Title: Measuring method for fine-particle-intensified light dispersion and aggregation
Inventor: EDA SHINICHI
IPC: G01N33/543
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which a wide dynamic range is obtained by measuring the amount of an analyte by using a mixture of strongly light dispersing particles comprising one highly reactive coupling partner with reference to the analyte and of weakly light dispersing particles comprising one low reactive coupling partner. SOLUTION: The size and/or the ratio of the refractive index of fine particles cause the dispersion of light at a wavelength which is used to detect aggregated fine particles. The size is selected generally so as to be substantially smaller or slightly smaller than the wavelength. A detection wavelength is usually 300 to 1200 nm, and the mean size of the fine particles is 30 to 60 nm. Strongly light dispersing particles and weakly light dispersing particles are of the same size, but they are formed of different materials. The material for the former has a refractive index which is larger than that of the material for the latter, and their ratio is set at 1:2. The ratio of blue density of the particles having the large refractive index to the density of the particles having the small refractive index is 0.01 to 5.  A suspension in a buffer solution is maintained by a mixture which is coated independently with a highly reactive coupling partner and with a low reactive coupling partner.

Abstract: PURPOSE:To attain high-speed access and to obtain an accurate tracking error signal by providing one or plural pairs of electrodes on an optical wave guide on a substrate and executing deflection using a wave guide lens having a wedge- shaped part to change its refractive index by an electrooptic effect. CONSTITUTION:A light beam from a semiconductor laser 1 becomes parallel beams by a collimator lens 2 and becomes a wave guide light beam by an incoming coupler 4 on an optical wave guide 3, and this wave guide light beam passes through plural wave guide lens 7-1-7-6 composed of electrodes 5 and 6, after that goes out to the external part of the optical wave guide 3 by an outgoing coupler 8, and converges on an optical disk 11 by an objective lens 9.

Title: Load transducer
Inventor: KIMURA ICHIJI
IPC: G01L1/10
Filed: 1986-09-25
Abstract: PURPOSE:To obtain a weighed value signal with high resolution by detecting the extent of the elastic variation of a cavity resonating housing by an oscillation circuit and a detecting circuit. CONSTITUTION:The cavity resonating housing 10 does not deform in a unloaded state where a load G is placed, so a feedback amplifier 14 oscillates a fundamental oscillation frequency. When the load G is placed, the part where the load G is placed deforms elastically in an inward direction as shown by an imaginary line A and the resonance frequency decreases below the fundamental oscillation frequency. The degree of the degree is expressed by a function of the load G, so the degree of the decrease in the frequency is measured through the detecting circuit 15 to know the value of the load G. Then the extent of the elastic deformation of the cavity resonating housing is detected by the oscillation circuit and detecting circuit, so no lever is required and the fundamental oscillation frequency is high, so that the weighed value signal having higher resolution than a crystal oscillator type load transducer is obtained.
