Title: Method and system for detecting spread spectrum signal
Inventor: OGINO AKIRA
IPC: H04B1/707
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To detect a spread spectrum signal even when the spread spectrum signal is deteriorated. SOLUTION: A spread spectrum additional information detection section 51 detects a correlation between a PN code string and a video signal Si on which a copy prevention control signal subject to spread spectrum processing is superimposed for each vertical period. In the case that the correlation between the copy prevention control signal subject to spread spectrum processing superimposed on the video signal Si and the inverse spread spectrum processing PN code is not in excess of a predetermined threshold level, the obtained correlation is being added for each vertical period.  The threshold level denoting whether or not the correlation between the copy prevention control signal subject to spread spectrum processing superimposed on the video signal Si and the inverse spread spectrum processing PN code is changed to detect the copy prevention control signal subject to spread spectrum processing superimposed on the video signal Si depending on the number of the vertical periods being the detection object of the correlation.

Title: Current detector
Inventor: KURIYAMA SHIGERU
IPC: G01R15/20
Filed: 1983-12-16
Abstract: PURPOSE:To increase a signal-to-noise ratio and to detect precisely a current by varying the control current of a Hall element to which a feed current is converted into the variation in magnetic flux density and applied when it exceeds the range of a measurement current. CONSTITUTION:Grips 3 and 4 movable pieces 1 and 2 are held to clamp a cable 15 and then released from being gripped, and then a support shaft 8 presses an iron core 7 with the reaction force of a spring 16 to contact an iron core 10, constituting a magnetic circuit. When a current flows through the cable 15, magnetic flux produced by the iron cores 7 and 10 varies in density and the output voltage of the Hall element varies to output a signal through a terminal-stage amplifying circuit 20. On the other hand, when a measurement is taken while the measurement range is narrowed down, the application of the control signal to a terminal C turns on a transistor TR1 to connect a resistance R in parallel to R4. Consequently, the voltage drop across a resistance R5 increases and conduction current of a TR2 increases to increase the Hall element control current, so the output signal increases to improve the precision.

Title: Reflector and liquid crystal display as well as electronic apparatus
Inventor: OKUMURA OSAMU
IPC: G02B5/30
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To make it possible to reflect external light much in a direction different from a specular reflection direction by providing the reflector with a light control plate which selectively scatters only the incident light within a prescribed angle range and allows the transmission of the incident light of angles exclusive of thereof and a light reflection plate. SOLUTION: This reflector is constituted by optically adhering the light control plate 101 and the light reflection plate 102 to each other by using a transparent adhesive having the refractive index approximate to the refractive index of the respective elements or without using the adhesive by heat welding. The light control plate 101 consists of a structure obtd. by laminating a transparent layer having the high refractive index and a transparent layer having the low refractive index and has the nature to selectively scatter only the incident light existing within the prescribed angle range and to allow the transmission of the incident light of the angles exclusive thereof. The light 111 entering from a light source 103 existing in a direction diagonal with the reflector transmits the light control plate 101 nearly as it is and is reflected by the light reflection plate 102.  The reflected light heads toward the specular reflection direction 113 (angle 114 = angle 115) and is scattered by the light control plate 101 at this time, by which much of this light is emitted to a normal direction 112.

Title: Optical film
Inventor: MORI YOICHI
IPC: B29C35/02
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To efficiently cut the zero-order light in a hologram cut filter and to prevent problems of decrease in contrast or decrease in chromaticity in a display device, by using long-chain dye molecules which has absorptivity to the component of light parallel to the axis of the molecule but have no absorptivity to the component of light in the normal direction of the molecular axis. SOLUTION: The long-chain dye molecules in the dichroic dye show different absorptivities of light depending on the direction of the molecular axis. The molecules have almost no absorptivity to the component of light in the normal direction of the molecular axis and transmit the light, but the molecules have absorptivity to the component of light in the parallel direction to the molecular axis and does not transmit light. Therefore, in a hologram color filter 5 with <=40 deg. incident angle of back light 3, for example, the diffracted light 15 with wavelength dispersion by the optical film 19 can be condensed into a liquid crystal display device without cutting, while the zero-order transmitted light 14 can be completely cut.

Title: Torque detector
Inventor: TAKAHASHI HISAYUKI
IPC: G01L3/10
Filed: 1989-09-12
Abstract: PURPOSE:To make it possible to detect the fluctuation of torque with high accuracy by coupling a magnetic plate to the housing of a speed-increasing gear mechanism, amplifying the amount of rotation difference of output shafts, and transmitting the value to the magnetic plate. CONSTITUTION:When torque fluctuation occurs in an input shaft 2, the amount of the torsion of a flexible shaft 13 is changed. Rotation difference is generated between a magnetic plate 4 of the shaft 2 and a magnetic plate 5 which is provided on the side of an output shaft 12. The magnetic plate 5 is coupled with a housing 9 of a speed-increasing gear mechanism 18. Therefore, the amount of the rotation difference between the shaft 2 and the output shaft 12 is amplified and transmitted to the magnetic plate 5. Thus, the rotation difference between the magnetic plates 4 and 5 caused by the torque fluctuation is detected highly accurately with number-of-rotation sensors 17 and 16. At the constant-speed rotation wherein torque fluctuation is not generated, the shaft 12 and the mechanism 18 are rotated as an integrated body. Relative intermeshing motion is not generated between the gears in the mechanism 18. Therefore, there is no mechanical friction loss, and the transmission efficiency is not decreased.

SOLUTION: After digging ahead to a prescribed position with shield machines 1, 2 in a connected state, a rear trunk part R and a deformed segment 13 is fastened. Then, a tail seal 20 is attached to a middle trunk part M of the shield machine 2, a segment 18 after separation is assembled using an erecter 9, and fastening mechanisms 30, 31 are removed. A segment 17 after separation is assembled to the shield machine 1 so that the shield machine 1 is driven with the segment 17 set to a reaction. When the shield machines 1, 2 are unified, the rear trunk part R and the middle trunk parts M of the driving shield machines 1, 2 are connected in a vertical shaft. A large-diameter tunnel can be thus branched and unified at low cost in a short construction term.

Abstract: PURPOSE:To avoid short-circuits between conductor patterns caused by excessive solder and facilitate design of high density wirings by a method wherein dams composed of insulating covering layers whose heights are larger than the heights of the conductor patterns are provided on a printed wiring board except on the parts of the conductor patterns. CONSTITUTION:Conductor patterns 12 are formed on a light transmitting board 11 and a photosetting resin layer 13 is formed on the surface of the board 11. If an ultraviolet radiation is applied to the rear of the board 11, the radiation is reflected by the conductor pattern 12 parts and does not reach the layer 13. Therefore, the parts of the layer 13 on the conductor patterns 12 are not cured and only the parts of the layer 13 not on the conductor patterns 12 are selectively cured. Then, if the uncured parts of the layer 13 are removed with water or suitable solvent, the conductor patterns 12 are exposed and the cured parts of the resin layer 13 are left on the board 11 except on the conductor pattern 12 parts to form dams 14. Solder paste or the like is applied to the conductor patterns 12 to form solder layers 15 and a printed wiring board 10 is completed. With this constitution, short-circuits between adjoining conductor patterns caused by excessive solder in a soldering process can be avoided and, further, high density wirings can be designed.
