Title: Magneto-optic disc substrate
Inventor: UEDA MASAYA
IPC: C08G64/14
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To obtain a magneto-optic disc substrate which is excellent in signal characteristics by specifying a glass transition temperature of a polycarbonate resin of an optical disc substrate, and a difference in a vertical refractive index of the substrate. SOLUTION: A difference in a vertical refractive index can be remarkably decreased by selecting a polycarbonate resin having a lower glass transition temperature than that of an ordinary polycarbonate resin for an optical disc. That is, in order to form a magneto-optic disc of a high recording density, the polycarbonate resin is required to have 100 to 140 deg.C as the glass transition temperature. For the resin exceeding 140 deg.C in the glass transition temperature, reduction of the difference in the vertical refractive index becomes very difficult to be achieved. Further, for the difference in the vertical refractive index, 300×10 or under is required. By satisfying this condition, a use value to the magneto-optic disc substrate which is excellent in signal characteristics, i.e., high in recording density, becomes extremely high.

Title: Frame synchronizing circuit
Inventor: NOMURA KENICHI
IPC: H04L7/08
Filed: 1985-10-09
Abstract: PURPOSE:To relax the speed requirement and package condition of an element when a high-speed signal is handled by a digital communication system by operating a channel rearranging circuit synchronously through a timer circuit and varying the phase of series-parallel conversion until synchronism is detected unless the coincidence between synchronous patters is not detected from data of respective channels of the channel rearranging circuit. CONSTITUTION:Data separated in optional phase relation by a series-parallel converting circuit 2 are rearranged correctly by the channel rearranging circuit 3 and a pattern detecting circuit A4 and a pattern detecting circuit B5 receive a synchronous pattern. When, however, the data are not rearranged in correct phase relation by the channel rearranging circuit 3, the synchronous pattern is not received. The timer circuit 11 when receiving a complete step-out from a synchronism protecting circuit 8 sends out a constant-period rearrangement signal with a constant period to the channel rearrangement signal to the channel rearranging circuit 3. Every time the channel rearrangement signal is inputted, the channel rearranging circuit 3 replaces data of both channels with each other and when they are replaced in correct phase relation, a synchronous detecting circuit 7 detects the synchronism and sends out a coincidence signal to the synchronism protecting circuit 8.

Title: Proofreading device of color picture scanning and method therefor
Inventor: UIRIAMU KEI SUMISU
IPC: G03B27/50
Filed: 1990-08-24
Abstract: PURPOSE: To obtain data quality equivalent to that obtained from a homogeneous illuminating source by correcting the output of a photodetector array scanned by image illumination generated from a fluctuating light source in a real time. CONSTITUTION: The charge signal of each photodetector line 38 is serially transferred to a multiplication processor 44. A signal generated by exposing the first several photodetecting cells in each line to a white reference sample is multiplied by 1, and the value is compared with a constant reference. The constant reference value is divided by an inputted white reference signal value, and a calibration coefficient is obtained. When a signal prepared by scanning a subject image pixel by the photodetecting cell in the same line is supplied to the processor 44, those signals are multiplied by the calibration coefficient for correcting deflection from exposure light intensity expressed by the constant reference value.  Thus, the output of the image scanning photodetecting cell can be calibrated in a real time for compensating the change of a light radiated from a low cost light source, and a high resolution digital copy can be obtained.

IPC: C12N5/0735
Filed: 1983-11-30
Abstract: PURPOSE:To measure reflected infrared absorption spectrum free from atmospheric effect of measurement, by alterating spectrum measurements by an infrared ray polarized vertically to the incident surface and an infrared ray polarized in parallel and measuring the ratio of these measurements. CONSTITUTION:An infrared ray from a source 1 is led to an interferometer, its output is subjected to linear (plane) polarization by a linear polarizer 3 and the polarized light is led to a polarization modulator 4. The modulator 4 is controlled by a micro-computer 12 and a polarizing plane of the input light modulates the polarizing plane in horizontal as well as vertical directions alternatingly with respect to a specimen surface. The infrared ray thus interfered, polarized and modulated is irradiated to the specimen 5 through a steep angle. The infrared ray reflected by the specimen is detected by a detector 6 and delivered to a processing unit A. The processing unit measures alternatingly a spectrum corresponding to vertical and parallel polarized rays and amplifies them by amplifiers 10, 11 respectively and the ratio is calculated by a micro-computer 12.

Title: Melt spinning of pitch
Inventor: OTAGURO YUKIHIRO
IPC: C01B31/00
Filed: 1991-09-04
Abstract: PURPOSE:To produce a high-quality pitch fiber while improving spinning workability and environmental safety by supplying an air current in the opposite direction to the yarn-adjoint stream from a spinning cooling chamber and preventing vibration of yarns and diffusion of low-boiling substance vapor. CONSTITUTION:A petroleum-or coal-based pitch is initially melted and discharged through a nozzle 1 by the conventional method and subsequently cooled by a cooling unit 2 directly under the discharge plane of the nozzle 1. While supplying, during this process, an air current through an air-supply opening 5 into the spun yarn-cooling chamber 7 in the direction opposite to a yarn- adjoint stream generated from the spun yarn-cooling chamber 7 by friction between the spinning fiber (Y) bundle and the air, melt spinning of the pitch is carried out. Since it is preferable to discharge the air from the spun yarn- cooling chamber 7 in an amount larger than that of the yarn-adjoint stream, a yarn-drawing method by a suction gun 3, capable of discharging the air in the spun yarn-cooling chamber together with the yarn-adjoint stream is preferably used.
