Title: Clock extraction circuit
Inventor: TAKASE ICHIROU
IPC: H03D3/00
Filed: 1978-07-24
Abstract: PURPOSE: To secure the steady extraction of the clock by using the shift register to use the multiplied carrier extracted as the shift clock to the delay circuit in case the phase detection is given to the phase-modulated reception wave and then the clock is extracted by the demodulated signal.  
     CONSTITUTION: The modulated wave supplied to input terminal 501 is branched off into two parts, and one of the branched wave is supplied to phase detector 506 through resonator 503, slicer 504 and 1/2 divider 505 each along with another wave. Thus the modulated signal is decoded, and the output is branched off into two parts. One of the branched output is converted into the clock pulse by slicer 508 via clock extraction circuit 507 and then supplied to decision circuit 509 along with the other output. And the base band signal is delivered. One of demodulated signal (a) supplied to input 601 of clock component extraction circuit 507 is delayed by shift register 602 which gives shift lock to double-multiplied carrier (b) and then supplied to exclusive logic sum circuit 603 along with another demodulated signal to extract the clock component to output 604.

Title: Knocking detector for internal combustion engine
Inventor: YAMAGUCHI KIMIAKI
IPC: G01L23/22
Filed: 1979-07-16
Abstract: PURPOSE: To improve the sensitivity of a detector by installing within a cylindrical housing a magnetic-flux detecting method and a magnetic path that has a formed gap opposing to a magnetic material including a vibrator made of the magnetic material fixed at the center magnetic path part.  
     CONSTITUTION: Vibrations of knocking occurring in a cylinder block are transmitted to vibrator 21 by way of housing 27, support 29 and magnetic material 23. Therefore, gap G between vibrator 21 and step 27c of housing 27 varies to vary magnetic resistance in a magnetic path, and consequently a voltage output that corresponds to the variation in magnetic flux is sent to coil 25. This signal is output to detecting circuit 3 by way of signal line 25d. Then, the resonance frequency of vibrator 21 can easily be adjusted to the knocking frequency by changing the length of reed piece 21a of the vibrator so as to improve the sensitivity of the detector to the knocking and further sensitivity to a vibration noise can also be lowered relatively. Thus, the sensitivity of the detector can be improved.

IPC: H04N5/44
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent illegal copy of a DVD disk by connecting an RGB-NTSC converter between a computer monitor and an RGB output of a device and displaying a recognizable artifact to impair easy visibility by a recorded signal. SOLUTION: The DVD disk is reproduced by a DVD-ROM drive 10 for computer. Data stored on the DVD disk is compressed according to an MPEG standard. A picture distortion artifact is added to a video signal to be outputted from an RGB converter 16 to prevent occurrence of the illegal copy. A YUV component of the video signal is supplied to a digital signal processor(DSP) 18. The video signal to be outputted from the RGB converter 16 is delayed, and during the delay, detail analysis is performed to an area of the picture to be exposed by the YUV component of the video signal by the DSP 18. When a certain area of minimum detail is selected, the picture distortion artifact is generated from a ROM 24 by the DSP 18.

Title: Manufacture of surface-decarburized steel strip
Inventor: NAKAMOTO KAZUNARI
IPC: C21D3/00
Filed: 1981-06-13
Abstract: PURPOSE:To make the depth of surface decarburization uniform when a hot rolled steel strip is annealed and decarburized by the oxidizing action of mill scale, by removing generated CO from the strip surface. CONSTITUTION:When a coil of a hot rolled steel strip is annealed and surface- decarburized by the oxidizing action of mill scale deposited on the surface, the annealing is carried out while removing CO generated by the oxidizing action of the mill scale from the strip surface. CO is removed by forcing the atmospheric gas to be ventilated or by evacuating the annealing furnace. The former method is suitable for loose coil annealing, and the latter method for tight coil annealing. A difference in the partial presure of CO between the centeral part and the edge parts of the strip in the lateral direction is eliminated. The difference is the maximum factor of causing ununiform depth of decarburization in the laterial direction. Accordingly, the depth of surface decarburization in the lateral direction of the strip can be made uniform.

Title: Method for checking silicon wafer
Inventor: YOSHIDA MASAMICHI
IPC: H01L21/66
Filed: 1981-06-12
Abstract: PURPOSE:To check the number of defects in the wafer by a non-destructive method readily by irradiating infrared rays on the wafer wherein the defects are yielded, and detecting the transmitted amount of the infrared rays which are transmitted through the wafer. CONSTITUTION:The Si wafer 3 is mounted on the sample mounting table of a double beam type infrared spectrophotometer 1 wherein wavelength is varied, e.g. in the range of 5-25mum. The defects 2 are imparted to the Si wafer 3 by the impact of the fine powder of SiO2 blown by a sand blasting method. The infrared rays are irradiated to the Si wafer 3 as shown by an arrow. The transmitted amount of the infrared rays from the Si wafer 3 is measured by an amplifier and the like which are built in the spectrophotometer 1 at a specified wavelength. The more the defects, i.e. the larger the impact, the larger the transmitted amount decreases.

Title: Decoding method for error correction code
Inventor: SAKO YOICHIRO
IPC: H04L1/00
Filed: 1986-04-21
Abstract: PURPOSE:To enable error correction for a random error, and a burst error, by executing the correction up to <=[(d-2)/2] symbol numbers when an inter- code minimum distance in an error correction code system is (d), and performing the error correction to <=d-2 symbol numbers, when the error correction is impossible. CONSTITUTION:Firstly, the same error correction as in a conventional method is performed. The correction, assuming the inter-code minimum distance as (d), is executed for the symbol up to an even number (t) that satisfies tr<=[(d-2)/2], and when the correction is impossible, the error correction for a continuous error due to the burst error, etc., is performed for the symbol up to a number (a) that satisfies a <=d-2. In this case, each position of error symbol group is decided by the detection of the position of an error symbol which becomes one reference, based on an assumption that errors (error symbol group) are continued according to a prescribed rule. And by applying the error correction on the symbol at each position, it is possible to perform the error coorection for up to (d-2)-number of the symbols.

Filed: 1987-04-14
Abstract: PURPOSE:To obtain a recording medium which permits optical reproduction by providing superconductive rings to one face side of a Faraday effect layer in the state of extending the same in the direction parallel with the main surface of the Faraday effect layer. CONSTITUTION:This recording medium is provided with the Faraday effect layer 4 consisting of a material which exhibits the Faraday effect and the superconductive rings 6 disposed on one face side of the Faraday effect layer in the state of extending the same in the direction substantially parallel with the main surface of the Faraday effect layer 4. Inducted current is kept passed semi-permanently in the superconductive rings by impressing the fluctuating magnetic field penetrating said rings from the outside. The plane of polarization of light is rotated by the Faraday effect in proportional to the distance at which the polarized light passes the inside of the Faraday effect layer 4 and the intensity of the magnetic field when the polarized light passes the inside of said layer. The presence of absence of memory is, therefore, read out by detecting the difference in the rotating angle of the plane of polarization of the light. Reproduction output, i.e., S/N is increased by increasing the intensity of the magnetic field to be impressed.
