Title: Digital signal recording and reproducing device
Inventor: SHIMEKI TAIJI
IPC: G11B20/18
Filed: 1985-10-28
Abstract: PURPOSE:To write as many as reproduction data in an error correction memory by adding an address showing the block order of divided data so as to decide whether an error can be pinpointed at an address or not and controlling writing data in the error correction memory. CONSTITUTION:A demodulator 7 demodulates a divided data block which is reproduced by a recording and reproducing device, and an address block generator circuit 9 generates the address added in order to show the block order at the time of writing. Only when the error place is decided at the address, writing block data in the error correction memory 11 is inhibited through a memory write control circuit 10. Accordingly the block data including an error is also written in the memory 11. A number of reproduction data ensure the probability of the error correction, whereby cases decided to be correction impossible can be reduced.

Title: Synchronizing separating and clamping device
Inventor: SEKIMOTO KUNIO
IPC: H04N5/18
Filed: 1984-11-15
Abstract: PURPOSE:To attain excellent synchronizing signal separation by amplifying a video signal before being fed to a comparator, clipping a beat noise superimposed on the tip of the synchronizing signal and clamping the result to set a reference potential of the comparator to a point having a margin for overshoot. CONSTITUTION:An amplifier 4 is provided after a clamp amplifier 2, the tip of the synchronizing signal in the output signal is clipped by a clip circuit 10 and a clamp circuit 5 and also clamped, then the result is fed to the comparator 6. In this circuitry, as a larger signal is fed to the input, the more the clipped amount of the synchronization tip is increased, and only beat noise superimposed on the synchronizing signal is clipped at a large input and then clamped at the same time. Although the clipped level is larger at a large signal, since the synchronizing signal itself is larger, the margin for overshoot is not deteriorated.

Title: Electric apparatus
Inventor: SAITO MUNECHIKA
IPC: H02B13/065
Filed: 1994-10-05
Abstract: PURPOSE: To install an insulation monitoring sensor to detect partial discharge generated inside an electric apparatus in simple structure, and prevent the sensor from picking up external noise. CONSTITUTION: In an electric apparatus having a junction part in a container 1, and provided with a sealed part at the junction part, a sensor comprising a coil 10 wound around a ferrite core 11 is disposed on the outer side of the sealed part at the junction part. When partial discharge is generated, electromagnetic waves generate a magnetic field inside the core. The search coil 10 detects change of the magnetic field. The insulation monitoring sensor is disposed on a junction surface of the container 1, so effects of external noise are not given. Because it is disposed on the outer side of the sealed part, a strict sealing structure is not required.

IPC: G11B5/716
Filed: 1987-09-25
Abstract: PURPOSE:To perfectly and magnetically separate two magnetic recording layers by providing a magnetic shielding layer consisting of a superconductor between two layers of the magnetic recording layers. CONSTITUTION:The layers of the magnetic recording layers 1, 3 are provided on a supporting body 4, and the magnetic shielding layer 2 consisting of the superconductor is provided between these layers 1, 3, and the layer 1 and 3 are separated perfectly and magnetically from each other by the layer 2. At the time of recording, the layer 2 is heated by a heater 5, and a part shown by hatching changes from a superconductive state into a normal conductive state. Then, the magnetic shielding action of only this hatched part disappears, and the recording to the layer 3 comes possible. Then, a signal is recorded in the layer 3 by a recording/reproducing magnetic head 6. At the time, the same signal is recorded in the layer 1 as well, but only the layer 1 is erased by an erasing head 7. Afterward, other signal is recorded in only the layer 1 by the recording/reproducing magnetic head 8. As mentioned above, two signals can be recorded in the respective recording layers as being perfectly separated.

Title: Error correction method for coded data
Inventor: MORIYAMA YOSHIAKI
IPC: G06F11/10
Filed: 1990-09-12
Abstract: PURPOSE:To improve the error correction speed and capacity of the method by correcting the error of data by performing threefold error-correction coding in three directions with three codes. CONSTITUTION:The error of data is corrected with the 1st code by performing threefold error-correction coding in three directions with three codes and, at the same time, the 1st flags are generated in connection with the number of errors. Then the number of errors is found by means of the 2nd code and the error is corrected by means of the number of errors and the 1st flag of each erroneous position. At the same time, the 2nd flags corresponding are generated to each symbol of the 2nd codes by referring to the number of errors, the 1st flags at erroneous positions, and the 1st flags to each symbol of the 2nd codes. Moreover, in the course of correction by means of the 3rd code, the correction is performed by deciding the correcting method by referring to the 2nd flags. Therefore, error correction is performed at a high speed and a high error correction capacity is exerted against a burst error.

Title: Laminated x-ray fresnel zone plate
Inventor: SAITO KAZUYA
IPC: G01N23/00
Filed: 1988-09-27
Abstract: PURPOSE:To suppress occurrence of working distortion and to stabilize the laminated structure of a multilayered film by forming the X-ray blocking section and X-ray transmitting section of the zone plate of such high-hardness materials that do not diffuse to the other sections even when the temperature becomes high. CONSTITUTION:The X-ray blocking section 10 of a laminated X-ray Fresnel zone plate is formed of such a high-hardness material that does not diffuse into an X-ray transmitting section 11 even in a high-temperature state instead of the conventional material and, at the same time, the section 11 is also formed of such a high-hardness material that does not diffuse to the section 10 even when the temperature becomes high instead of the conventional material. Therefore, occurrence of working distortion can be prevented when a rod-like body 2 surrounded by a multilayered film is thinned and, at the same time, the unevenness on the surface of each layer can be minimized even when the number of laminated layers of the multilayered film is increased. Moreover, mutual diffusion does not take place between the X-ray blocking section 10 and X-ray transmitting section 11 even the temperature becomes high.
