Title: Liquid crystal display element
Inventor: SHIRASAKI TOMOYUKI
IPC: G02F1/13357
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To prevent a double image from being generated. SOLUTION: When a specified voltage is applied to a liquid crystal panel 40, the polarization direction of linearly polarized light passing through a reflection type polarizing plate 30 and a polarizing plate 50 is changed by 90 deg. and when the specified voltage is not applied, the polarization direction of the light is not changed. The reflection type polarizing plate 30 transmits only the light polarized in a specified direction and reflects other light. An optical retardation plate 20 changes linearly polarized light passing through the reflective polarizing plate 30 into circularly polarized light, and when the reflected light of that light is again made incident, the plate 20 again changes the light into linearly polarized light. Besides polarization directions of the linearly polarized light before and after the reflection are orthogonally crossed with each other.  An organic EL element 10 is provided with a transparent electrode and a light- reflecting metal electrode, reflects light transmitted through the optical retardation plate 20 and emits light by application of voltage.

Title: Coordinate reader making use of electrostatic coupling
Inventor: KOBAYASHI MASAHISA
IPC: G06F3/041
Filed: 1979-03-26
Abstract: PURPOSE: To take an accurate read under no influence of noises while coupling impedance in the read is reduced by obtaining an output coordinate signal by applying the output coordinate signal to a table after modulating and then by demodulating the coordinate signal read via a transmitting pen.  
     CONSTITUTION: In a coordinate reader making use of electrostatic coupling with reduced coupling impedance between a coordinate table and transmitting pen, transmitting pen 1 is placed closely over table 11 with a signal line showing coordinates so as to read coordinates. Here, modulators 15a...15c, and 16a...16c modulate a coordinate signal by a carrier higher in frequency than an output coordinate signal and demodulator 14 demodulates the modulated coordinate signal. After being modulated, the output coordinate signal is applied to table 11, where the modulated coordinate signal read via pen 1 is demodulated into the output coordinate signal. Thus, the coupling impedance in the read can be reduced and the accurate coordinate read can be taken without being influenced by noises.

IPC: G02F1/1347
Filed: 1989-02-14
Abstract: PURPOSE:To reduce the thickness and weight of the above element and to control a cell gap with high accuracy by forming the liquid crystal cell for display of two sheets of glass substrates and further, using one of the glass substrate as a common glass substrate and forming the liquid crystal cell for compensation of this common glass substrate and a flexible film substrate. CONSTITUTION:The one 21B of the glass substrates of the liquid crystal cell 20 for display is used commonly as the substrate of the liquid crystal cell 10 for compensation and further, the other substrate 11 of the liquid crystal cell 10 for compensation, i.e., the substrate on the side in contact with a polarizing plate 16 is formed of the flexible film substrate. Namely, the liquid crystal display element is constituted of the three substrates; two sheets of the glass substrates and one sheet of the flexible film substrate. The thickness and weight of the element are reduced in this way; in addition, the control of the cell gap is easy even when the element is formed to a larger size. The need for grinding the glass substrate surface on the liquid crystal cell side for compensation is eliminated and the cost increase by grinding is reduced. The inexpensive two-layer type liquid crystal display element with which the production is easy is thus obtd.

Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To provide a method capable of obtaining light metallic parts represented by a partial composite aluminum alloy having the actually required low volumetric rate (low Vf). SOLUTION: A slurry (suspension) is prepd. by using powdery particles (more specifically, ceramic particles or particles forming an intermetallic compd. with a metallic base material) in place of using whiskers (fibers) as a reinforcing material and mixing these powder particles, alumina sol and water. A dehydrated member obtd. by filtering the moisture in the slurry is compression molded and is then sintered to form a preform. After the preform is disposed in a casting mold, the melt of the light metal, such as aluminum alloy, is poured into the casting mold and the gaps in the preform are impregnated with the molten metal by high-pressure casting, by which both are combined.

Inventor: OKADA MASAMICHI
IPC: G01K7/00
Filed: 1986-02-19
Abstract: PURPOSE:To display a measured value when the raise rate of the measured value of a clinical thermometer decreases below a specific value by deciding whether or not the rise rate of the measured value of temperature is below the specific value and switching an estimated value display to a measured value display. CONSTITUTION:The clinical thermometer 11 estimates convergent temperature from the measured value detected by a temperature sensor 12 and displays the estimated value. When the sensor 12 detects the bodily temperature, its detection signal is A/D- converted 13 and then inputted to a CPU 14. The CPU 14 inputs the detection signal, i.e. measured value at intervals of specific sampling time to output and stores it in a memory 15, and also outputs the measured value to a display device 16, which displays the measured value. Namely, an estimation switching means 5 switches the measured value display of a display means 3 to the estimated value display after the estimation of the estimating means 4 and then a rise calculating means 6 calculates the rise rate of the measured value; and a decision means 7 judges whether or not the rise rate is less than the specific value and a measured value switching means 8 switches the estimated value display to the measured value display when the rise rate becomes a low raise rate.

Abstract: PURPOSE: To improve the storage efficiency of a board and reduce the number of processes at low cost by combining a plurality of printed boards by connecting them by a conductor which electrically connects the boards and also operates as a hinge. CONSTITUTION: A flexible conductor 11 is inserted into each conductor mounting hole of a printed board 21 and a separate board 25. Then, an electronic component 8 and the conductor 11 is soldered at one time, the temporary junction part 10 of the separate board 25 is separated by cutting at the inserting port 15 by nippers. The separate board 25 is bent at the conductor 11 vertically to the printed board 21, and the separate board forms three-dimensional body with the plurality of printed boards 2 which form a flat body. Thus, the separate board 25 is erected by bending the conductor 11. Since the conductor 11 also electrically connects the printed board 21 and the separate board 25, the conventional connecting operation is eliminated. Therefore, the storage efficiency of the board is improved and the number of processes is reduced at low cost.
