IPC: G01N27/12
Filed: 1991-01-25
Abstract: PURPOSE:To provide a humidity sensing element which can be used continuously for a long time without requiring any complex circuit by forming on a silicon wafer such polyimide resin the capacity value of which varies much with relative humidity and reverts to its initial value even if the resin is left in high- humidity atmosphere at high temperatures for a long time and then returned to a low-humidity state. CONSTITUTION:An ohmic contact electrode 1 is formed on the reverse face of an N-type silicon wafer 2. Polyimide resin is applied to the surface of the silicon wafer and dried and a solvent is removed therefrom and then the resin is heated and hardened to form a polyimide humidity-sensing film 3. The polyimide resin is soluble in an organic polar solvent obtained by the polymerization and formation into imide of a biphenyl tetracarbon acid group and an aromatic diamine group. Then an upper electrode 4 is formed and a semiconductor substrate is cut into an opening of chip size 5mm in diameter and upper and lower electrode takeout lead wires 5, 6 are attached to the respective portions of the substrate.

Title: Liquid crystal display device
Inventor: ABE HIDETOSHI
IPC: G09F9/00
Filed: 1978-05-24
Abstract: PURPOSE: To define the spiral axes of cholesteric liquid crystal as to become constant with respect to substrate surfaces by treating the surface of the substrates with a fluorine base surface active agent.  
     CONSTITUTION: After the glass substrates 1, 1' provided with transparent electrodes 2, 2' are dipped in the dilute solution of an F-base surface active agent, they are heated and dried, whereby surface active agent films 3 are formed on the substrate surfaces. In case the substrate surfaces are not treated, the spiral axes 5 of cholesteric liquid crystal 4 face random in all directions. In case the films 3 are provided in contrast with this, the liquid crystal molecules try to become perpendicular with respect to the substrate surfaces and therefore the axes 5 of the liquid crystal 4 become parallel to the substrate surfaces. This enables the cholesteric-nematic (n) phase transfer type liquid crystal display element to be driven at low voltages. When voltage is applied, the spiral structure of the liquid crystal 4 which had showed a white turbid state breaks down the transfers to the N liquid crystal and moreover the N liquid crystal molecules array in the direction perpendicular to the substrate surfaces, thus assuming a transparent state.

Title: Window sash incorporating planar heating element with self-controlling function
Inventor: YUASA SHUJI
IPC: H05B3/14
Filed: 1995-02-13
Abstract: PURPOSE: To keep window panes from fogging at low electricity rate without requiring extra space by incorporating a planar heating element with a specific function inside a window sash. CONSTITUTION: A planar heating element 1 which has the function of controlling current flow by varying its resistance value with temperature changes is incorporated into a sash 2 for heating. Convection of warm air is thereby caused to keep window panes from fogging. Since the sash is heated at temperatures matching indoor temperature by the planar heating element having a self- controlling function, the current carried is controlled, and electricity rate can be made lower than can be with heating wires. The sash can be fabricated in sizes that are not different from conventional ones because of the planar heating element being film-shaped and thin, so extra space is not required.

IPC: G11B7/005
Filed: 1993-03-22
Abstract: PURPOSE:To eliminate the sence of incompatibility even when change time is long by reporting a state just under a disk change by outputting the sound of another source during the disk change. CONSTITUTION:A power source switch 21 is turned on, and electric power is supplied from a power source part 20 to a CD changer control unit 25. Corresponding to the setting of a sound changeover switch 24, a control part 18 detects whether it is just under the disk change or not by using a signal 22 from an operation detection part 11 of a CD player part 10. When it is just under the disk change, the sound of an audio source 12 excepting for CD, reporting sound stored in a memory 14 or silence is selectively set. The sound is passed from a volume setting part 15 through a volume adjusting part 16 and generated from a speaker 19 by a main amplifier 17. Thus, even when the change time is long, the sence of incompatibility is not applied to an operator.

IPC: G01B11/02
Filed: 1982-04-14
Abstract: PURPOSE:To obtain an exact focal length as a digital value, by moving a slit to synchronize the position signal of the slit and the output of a photomultiplier, measuring the distance of a chart image and performing calculation by a magnification method. CONSTITUTION:A cover 20 of a support device 2 for a lens to be measured is opened, and a lens 15 to be measured is mounted to a lens mount 18 from a chamber 21. When a light source device 1 is operated, the scattered light past a diffusing plate 11 and a filter 12 passes through the slit of a chart 13, is collimated to the parallel light of a narrow width by a collimator lens 14, passes through the lens 15 along the optical axis 5 and enters a measuring device 3. The output of a photomultiplier 25 is maximized when the focus matches with the slit 40 in the device 30. A focal length (f) is calculated by the equation f=f0Z/Z0 from a reference focal length f0 and a reference pitch Z0. The result is fed to a printer and display to display the same.

Title: Frequency modulator
Inventor: AOTA TOSHIO
IPC: H03C3/00
Filed: 1985-03-27
Abstract: PURPOSE:To avoid response of a PLL to a modulation signal by applying the modulation signal to a voltage controlled oscillator or a PLL synthesizer using a reference oscillator for the purpose of frequency modulation so as to use said modulation signal for the modulation of the said reference wave. CONSTITUTION:An output of a reference oscillator 12 is subjected to frequency division by a frequency divider 13 and the result is inputted to a PLL circuit and outputted from an output terminal 10b in a desired frequency. In this case, a modulation signal inputted from a modulation signal input terminal 10a is fed to a voltage controlled oscillator 16 to apply frequency modulation. Since the natural angular frequency (limit frequency responded to by a PLL loop) has to be selected to a small value so as not to be affected with the modulation angular frequency by the procedure only above, the modulation signal is fed also to the reference oscillator 12 to apply frequency modulation to the reference wave by the modulation signal, thereby increasing the natural angular frequency of the PLL circuit regardless of the modulation angular frequency.

Abstract: PURPOSE:To enhance the accuracy of measurement and make sampling of specimens easy by depositing molten slag on a steel plate of surface roughness 25mum or under and surface temperatures 600 to 700 deg.C and making the same to a thin-plate-from solid. CONSTITUTION:Slag is flowed onto a steel plate of surface roughness 25mum and surface temperature 600 to 700 deg.C and is then solidified, after which it is peeled by giving impact and the pieces of a suitable size necessary for the fluorescent X-ray analysis apparatus are selected to provide specimens. It is equally satisfactory to prepare the specimens by dipping a steel plate 3 in molten slag 1, once pulling the same up, giving impact to the slat deposited on the surface to peel the slag and again depositing the steel plate into the molten slag while the temperature of the steel plate is at 600 to 700 deg.C. In this way, sampling of slag specimens is feasible with ease and in a short time and yet component measurement may be accomplished by the fluorescent X-ray analysis apparatus with good accuracy.

IPC: G02B5/20
Filed: 1995-03-22
Abstract: PURPOSE: To improve the flatness of the surfaces of colored layers by flattening the ruggedness of light shielding layers by flattening layers, then forming the colored layers thereon. CONSTITUTION: The color filters consist of the light shielding layers 2 which are patterned and formed to partition the surfaces to plural regions, the flattening layers 3 which consist of transparent resins formed to flatten the ruggedness of the base material surface by the light shielding layers 2 and the plural colored layers 4 which are formed to comply with the patterns of the light shielding layers 2 on the surfaces of the flattening layers 3 on the surface of a transparent base material 1. The flattening layers 3 are formed by applying the coating material contg. the transparent resin on the surface and curing the coating or solidifying the coating by drying. The flattening layers 3 are usually so formed as to cover the transparent base material 1 and the light shielding layers 2.  The smaller thickness of the flattening layers 3 between the light shielding layers 2 and the colored layers 4 is more preferable to prevent the light leakage from the flattening layers 3 and the oozing of colors arising therefrom. In such a case, the film thickness of the flattening layers 3 is preferably reduced by polishing the layers prior to formation of the colored layers 4.
