Title: Method and system for checking design rule
Inventor: MATSUI TAKASHI
IPC: G06F17/50
Filed: 1995-06-29
Abstract: PURPOSE: To sharply reduce the generation of false errors due to the check of a design rule in a semiconductor' integrated circuit device. CONSTITUTION: A graphic computing part 3 inputs the pattern data of a reference cell from a graphic input part 2, checks a design rule and outputs the checked result to an error graphic output part 4, which displays a circuit graphic on a display part 5. A designer extracts a false error by the use of a false error selecting part 6 and stores the extracted false error in a false error storing part 7. The computing part 3 inputs the pattern data of the whole semiconductor chip from the input part 2 and checks a design rule and a sub-computing part 8 sub-computes the false error data stored in the storing part 7 and displays a circuit graphic from which the false error stored in the storing part 7 is removed on the display part 5.

Title: Electromagnetically inducted electrical device
Inventor: ISHIHARA AKIHIRO
IPC: H01F27/36
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To suppress abnormal vibrations of an electromagnetic shield part by fastening an electromagnetic shield which is formed by bonding, laminating and integrating magnetic steel plates to a tank wall adjacent to a coil and a connecting conductor. SOLUTION: An electromagnetic shield 21 is formed by bonding with adhesive magnetic steel plates, cut into a rectangular shape and integrating them, and is fastened to the inner walls of a lower tank 4a and an upper tank 4b. An adhesive exhibiting a high adhesive strength such as epoxy base adhesive is used or welding is performed for bonding. The cross-sectional secondary moment and the cross section coefficient are increased dramatically by increasing the height of the shield. Reduction in plate thickness of the tank and downsizing of a reinforcing member can be realized by designing the strength of the tank, by directly welding the electromagnetic shield 21 formed through bonding and integration of the magnetic steel plates. The space for mounting the electromagnetic shield 21 can be reduced, the weight is reduced, and sagging of the multilayer magnetic steel plates is prevented.  Also, since the electromagnetic shield 21 is bonded to the tank through direct welding, level of vibration and noises during operation can be suppressed.

Title: Examine method of printing quality
Inventor: YOZEFU AA FUUBA
IPC: G06T1/00
Filed: 1979-12-18
Abstract: The differences between the scanned values of corresponding image points of a specimen and an original are formed by point-by-point scanning and comparison with an original. The difference values are subjected to a tone or shade correction, and then a weighting process and a minimum threshold correction. In the shade or tone correction, a mean value formed from the difference values in a specific surrounding area of the associated image point is subtracted from each difference value. The weighting process is effected individually for each image point and results in systematic errors and critical image zones not producing faulty assessments. The weighting factors are determined by statistical analysis of specimens which are assessed as good visually. The minimum threshold correction eleminates all those pre-treated difference values which are below a certain minimum threshold. The difference values of the points surrounding each image point are added algebraically with distance-dependent weighting to the remaining difference values of each image point. The resulting values are compared with a threshold value for each image point. If these values exceed the threshold value at least at one image point, the specimen is assessed as faulty.

Title: Method and apparatus for spread spectrum power line carrier communication
Inventor: ENDO KAORU
IPC: H04J13/16
Filed: 1985-07-24
Abstract: PURPOSE:To prevent overlapping of transmission signals by using an output of a correlator in a slave device so as to confirm the presence of a transmission signal from other slave device on a power line, and sending the transmission signal of the own device only when no transmission signal exists. CONSTITUTION:In receiving a transmission information signal of a sensor 17, a synchronizing control circuit 24 controls a clock control circuit 7 so as to allow M series code generating circuits 8, 9 to make each slave device generate a M series code having a specific phase difference and whose phase is shifted sequentially. Then the circuit 24 supervises an output signal of a correlator 23 until the said phase is circulated at least once. When other slave device sends the transmission information signal to the master device, the spread modulation signal is inputted to the correlator 23 via a reception amplifier 5. While the circuit 24 applies at least one circulation of the phase shift operation of the M series code, the output signal of the correlator 23 is obtained. Thus, the circuit 24 stops the phase shift control to supervise the output of the correlator 23 and a switch control circuit 25 blocks the closing of a switch 22 until the transmission of the slave device during transmission is interrupted. Further, the master device identifies the slave device sending the transmission signal depending on the phase difference of the code sent from the circuits 8, 9 of the slave device.

Abstract: PURPOSE:To facilitate the removal of jamming paper and to improve the efficiency of the operation by dividing a machine frame into 2pt, i.e. upper and lower frames being bordered by a form conveyance path, and opening them when paper jams. CONSTITUTION:A rotating shaft bracket 7 is formed stood on a base frame 6 constituting a bottom surface at one of four corners of the lower frame 3, e.g. paper feed side or rear side. The upper frame 2 is provided with a bracket 8 corresponding to said bracket 7 while both brackets 8 and 7 are linked with each other rotatably. If paper jams in the form conveyance path in this constitution, the paper discharge surface of the upper frame 2 is assisted by a gas spring 10 when lifted to elevate other three corners arcuately and diagonally from the lower frame 3 around the rotating shaft 9 positioned at said paper feed and rear side, so that not only the paper discharge side of the form conveyance path, but the paper feed side are opened large. Thus, the form conveyance path is expanded to facilitate the removal of jamming paper and the maintenance.

Title: Optical transmission path
Inventor: KOBAYASHI RIYUUJI
IPC: G02B6/028
Filed: 1984-08-04
Abstract: PURPOSE:To obtain an optical transmission path which is stable in the heat hysteresis of the refractive index and has a smooth refractive index distribution with high productivity by forming the optical transmission path contg. co-doped boron and fluorine in quartz glass and having the refractive index distribution in which the center of the optical transmission path is made to upper limit and the refractive index decreases in the radial center from said center. CONSTITUTION:Co-doping of boron and fluorine into quartz glass to manufacture an optical transmission path is accomplished by mixing boron trifluoride as a material for controlling refractive index to a silicon compd. which forms silica by oxidation at a molar ratio ranging 0-1.5. Mixing of the boron trifluoride with the silicon compd. is accomplished by a method consisting in mixing dividedly the same plural times while decreasing stepwise the mixing ratio from the upper to lower limit of the above-mentioned mixing ratio. If the mixing ratio of the boron trifluoride to the silicon compd. exceeds 1.5, the deposition rate of the silica decreases. Such optical transmission path does not decrease the deposition rate of the doped quartz glass and the resulted low refractive index glass is hardly subjected to heat hysteresis.

Abstract: PURPOSE:To improve solderability and soldering strength by specifying the compsn. weight ratios of Co, Sb, Bi, In, Ag and Ga and consisting of the balance Sn. CONSTITUTION:This leadless solder alloy is composed of 0.05 to 5.0wt.% Co, respectively 0 to 5.0wt.% Sb, Bi, In, Ag and Ga and the balance Sn. The solderability, i.e., the ease of soldering are improved and simultaneously, the soldering strength is enhanced when the Co is added to the Sn.
