Title: Liquid crystal display device
Inventor: IWATA TOSHIRO
IPC: G02F1/1343
Filed: 1990-11-29
Abstract: PURPOSE:To prevent the electric power lines extending from picture element electrodes to common transparent picture element electrodes from forming a radial shape in the edge parts of the picture element electrodes by providing hole patterns in the parts of the common transparent picture element electrodes facing the edge parts on the root side in the rubbing direction of the picture element electrodes. CONSTITUTION:The common transparent picture element electrodes ITO 2 face the transparent picture element electrodes ITO 1 provided for each of the picture elements on a lower transparent glass SUB 1 side and the optical state of a liquid crystal LC changes in response with the potential difference between the respective picture element electrodes ITO 1 and the common transparent picture element electrodes ITO 2. Hole patterns HPT 1 are provided in the parts of the common transparent picture element electrodes ITO 2 facing the edge parts on the root side in the rubbing direction of the transparent picture element electrodes ITO 1. The electric lines of force extending from the transparent picture element electrodes ITO 1 to the common transparent picture element electrodes ITO 2 are, therefore, prevented from forming the radial shape in the edge parts of the transparent picture element electrodes ITO 1. The liquid crystal LC, therefore, rises in a uniform state over the entire surface of the transparent picture element electrodes ITO 1 and the generation of domains is obviated.

Title: Concrete thickness measuring method using hammer sound
Inventor: ITO YOSHIHIRO
IPC: G01B17/02
Filed: 1992-11-11
Abstract: PURPOSE:To measure thickness of concrete by collecting secondary hammering sound being radiated to the surface of concrete after passing through the interior of concrete and detecting resonance frequency of the longitudinal wave of hammering sound. CONSTITUTION:An arbitrary concrete surface is hammered by means of an impact hammer 10. Primary hammering sound propagating in the air is not collected but secondary hammering sound being radiated from the concrete surface after propagating through the concrete is collected through a sound collecting section 21 of a microphone 20 and the secondary hammering sound thus collected is then analyzed at an analyzing unit 22 thus measuring the thickness of concrete. In this regard, it is well known that a specific relationship is satisfied between the thickness of concrete and the resonance frequency of longitudinal wave. Consequently, when a microphone 20 resonant to the resonance frequency is employed and a prominent resonance frequency is read out, the thickness of concrete can be measured easily.

Title: Combustion in furnace
Inventor: NAKAMACHI ICHIRO
IPC: F23C99/00
Filed: 1987-12-23
Abstract: PURPOSE:To reduce generation of nitrogen oxides to a low level by providing air supply-exhaust devices in a pair each forming a regenerative chamber in part and in an arrangement having a fuel feeding means interposed therebetween. CONSTITUTION:The air from a blower 5 is channeled as shown by a solid arrow line by a switching valve to feed into an air supply-exhaust device 1 on the left while fuel is constantly fed into the furnace 7 through a fuel feeding means 4 so that the fuel and the air burn after mixing with the combustion gas in the furnace. The exhaust gas goes into an air supply-exhaust device 1 on the right and is cooled as it passes through a regenerator 3 and, drawn by an exhaust fan 8 as shown by a broken arrow line, is let out. After an interval of time, the switching valve shifts the channel for the supply of the air for combustion to the opposite one. Thus the function of the air supply-exhaust devices 1 during combustion is alternated between the supply and the exhaust while the fuel is in continuous supply. With the above-mentioned setup, the fuel feeding means 4 and the air supply-exhaust devices 1 are so disposed mutually as not to allow easy mixing but to allow the fuel and the air to separately mix with the gas in the furnace rather than to mix directly so that the combustion can be prevented from being locally overheated.

Title: Current transformer
Inventor: OCHI NAOTERU
IPC: G01R33/032
Filed: 1989-12-14
Abstract: PURPOSE:To suppress the detection error due to external magnetic flux to a low level by almost uniformly winding predetermined winding around an iron core with a gap two or more times over the entire periphery thereof. CONSTITUTION:Main magnetic flux phil is refluxed to an iron core 6 with a gap by the current flowing to a conductor 2 and the current of the conductor 2 is detected from the light output of a Faraday element 8 modulated by the magnetic flux phil. Since voltages same in both of polarity and magnitude are generated in respective windings 12a - 12d by the main magnetic flux phil, the voltages are set off mutually and no current flows to all of the windings. Fur ther, voltage is induced in the windings 12a - 12d even by the external magnetic flux generated by the current flowing to a conductor of other phase to penetrate in a current transformer 5. In this case, since a current flows to the respective windings in a direction and magnitude negating the external magnetic flux, the external magnetic flux can be removed over the entire periphery of the iron core 6. The generation of the detection error caused by the change of the magnetic resistance of the whole of the iron core 6 is suppressed and detec tion accuracy is enhanced.

Title: Password number notice
Inventor: IWASA HIROSHI
IPC: B42D15/10
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To reduce a cost simplified in a constitution by sequentially laminating a dark color print layer printed with a dark color ink and an ultraviolet emitting layer solidly printed with an ink containing a fluorescent pigment on a surface of a cut form sheet piece having a password number fill-in column. SOLUTION: A password number 3 filled in a surface of an ultraviolet emitting layer 2a of a password number fill-in column 2 is difficult to be clearly read caused by a dark color print layer 2b. Since there is a density difference between the filled-in number 3 and a surface of the column 2 and light reflectivities of both the surfaces are different, the number can be accurately confirmed by altering its observing angle. A matt film made of a propylene having good ultraviolet transmissibility or a nonwoven fabric is adhered to cover the column 2. Then, since a light is reflected irregularly, the number 3 filled in the layer 2a of the column 2 cannot be visually observed even by altering the observing angle.
