Title: Digital information reproducer
Inventor: AMADA NOBUTAKA
IPC: G11B20/10
Filed: 1992-12-10
Abstract: PURPOSE:To make possible stabilized reproduction of a clock when a reproduced digital information signal is detected using a partial response(PR) class 4 system. CONSTITUTION:Digital information signals reproduced from a magnetic tape 1 are equalized through an equalizer 4 according to PR(1, -1) system and then equalized through a (1+D) operating circuit 5 according to PR class 4 system and the signals thus equalized are fed to a tri-level discriminator 6 where original digital information is attained. On the other hand, output signals from the equalizer 4 equalized according to PG (1, -1) system are fed to a clock component extracting circuit 7 comprising a level shift circuit interposed between two square circuits, for example. A signal having such signal spectra as the bit frequency components of reproduced digital information signal appear as high level emission line spectrum is produced and fed to a PLL circuit 8 where a clock signal having phase locked to the bit frequency component is obtained.

Title: Optical reception circuit
Inventor: IRIE HIRONORI
IPC: H04B10/2507
Filed: 1990-11-30
Abstract: PURPOSE:To improve a maximum input level for normal operation by adding a clamp circuit to limit an output signal of a preamplifier to a prescribed amplitude to the reception circuit. CONSTITUTION:A clamp circuit 5 to limit an output signal of a preamplifier 2 to a prescribed amplitude is provided to the reception circuit. Thus, the linearity of a gain variable amplifier 3 is lost by allowing the clamp circuit 5 to clamp an output level of the preamplifier 2 to be less than a maximum drive amplitude and a maximum input amplitude of the gain variable amplifier 3, but the waveform distortion in the preamplifier 2 and the gain variable amplifier 3 is minimized and malfunction of an identification recovery circuit 4 at a post-stage is avoided. Thus, the maximum optical input level for normal operation is improved.

Title: Preparation of sample for transmission electron microscope
Inventor: FUJII SHINJI
IPC: G01N1/32
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To realize a method in which the image quality of a transmission electron microscope is enhanced when a sample for the transmission electron microscope is created, by a method wherein a process in which an anodic oxide film is formed on the sample is installed and a process in which the anodic oxide film is removed is installed. SOLUTION: A defect in a specific position on a semiconductor substrate is indicated by a mark X. A sample is shaved down to a width of, e.g., 200 mm by a mechanical polishing operation using an abrasive. The sample near the mark X is shaved by a focused ion beam(FIB) working apparatus, and the sample is made thin down to a thickness of 300 to 500 nm. The sample is turned by 90 deg. to the front, an anodic oxide film is formed on the surface of the sample by a jig, and the anodic oxide film is then removed. At this time, the semiconductor substrate is retreated by a thickens of 50 nm. After that, an electron beam is transmitted to directions of arrows inside a transmission electron microscope, and the sample is observed.  When the anodic oxide film is formed and removed in this manner and when a damage layer on the surface of the sample is shaved, an image of better quality can be observed when the image by the transmission electron microscope is observed. That is to say, a lattice image having a most adjacent atomic interval can be observed.

Abstract: PROBLEM TO BE SOLVED: To eliminate an interfering background noise due to scattered beams from a scattering source and to obtain the beam amplitude by fetching multiplex and interfere output with a photo detector while changing relative phase difference by a phase-changing means and performing the arithmetic operation of the coefficient of the vibration constituent of a frequency with an operation means. SOLUTION: The emission beam from a laser light source 13 is split by a half mirror 700 and is made incident on a half mirror prism 30 as a reference beam and is made to multiplex and interfere with a scattered beam. A phase change element 711 for continuously varying the phase of a transmission beam is inserted into the light path of the reference beam as a phase-changing means, thus changing the relative phase difference between the reference beam and the scattered beam. A photomultiplier 22 that is a photo detector outputs the coefficient of the vibration constituent of the frequency.  The obtained coefficient is read by a computer 11 and is further subjected to an arithmetic operation, thus obtaining the amplitude of the scattered beam and hence forming a scanning-type near field optical microscopic image for expressing chemical information on a sample surface without any noises due to a scattering source.

Title: Method for generating shading correction data for image reader
Inventor: OUE YUJI
IPC: H04N1/401
Filed: 1994-12-19
Abstract: PURPOSE: To reduce the cost of the reader and to provide an excellent image against a secular change or the like by correcting the output of a scanner with no original set while replacing values of part without a white level reference member with a specific value. CONSTITUTION: White reference member for collecting shading correction data is separated into plural numbers and they are arranged on a scan line in contact with a target glass. In the case of generating the shading correction data, a control section 1 discriminates whether or not an original is set on a scanner 7 when a counter for shading correction data collection is counted up. When no original is set, the scanner 7 reads the scanning lines and an A/D conversion value of the scanner output for each picture element is written in a video RAM 4. Then shading correction data are obtained by interpolating the values without the white reference members in the scanner output with the white level reference member at both sides of the absence part through linear estimation. Thus, it is not required to store correction data in advance.

Filed: 1989-12-22
Abstract: PURPOSE:To adjust the quantity of supersaturated supply ink, and to keep the quality of printing excellent at all times by mounting an ink absorber drawing the surface of a ribbon and absorbing supersaturated supply ink into the carrying path of the ink ribbon. CONSTITUTION:An ink absorber 7 is formed by a felty member or a member such as the loop side face of an engaging member having detachable both surfaces. An ink ribbon 6 stores ink more than its own capillary phenomenon capacity and supersaturated supply ink more than required exists on the surface of the ribbon 6 under a floated state when a ribbon driving gear 3 on which ink is transferred by an ink supply body 2 receives the supply of excess ink when the ribbon 6 is fed with ink by revolution. The ribbon 6 passed through the ink absorber 7 draws and equalizes supersaturated supply ink floating on the surface of the ink absorber 7 by the resiliency of the absorber 7, and supersaturated supply ink is absorbed and stored in the supersaturated supply ink absorber 7 by a capillary phenomenon. Accordingly, the ink ribbon 6 passed through the ink absorber 7 holds the proper quantity of ink at all times, thus keeping the quality of printing under an optimum state.
