Title: Magneto-optical recording medium
Inventor: YASUDA KOICHI
IPC: G11B11/105
Filed: 1990-10-18
Abstract: PURPOSE:To improve anti-corrosiveness and weathering by providing a transparent dielectric layer comprising a specified compound one side or both sides of an magneto-optical recording layer. CONSTITUTION:Dielectric layers 2a and 2b comprising a mixture of aluminum nitride and boron nitride are arranged on one side or both sides of a magneto- optical recording layer 3. As the mixture is stable chemically as compared with the conventional single aluminum nitride, a large protecting action is obtained with respect to the magneto-optical recording layer. In addition, as a refractive index becomes large, a large action of amplifying an angle of rotation of a polarized light is noted as caused by a Kerr effect.

Title: Production unit for single crystal silicon and its production
Inventor: TOMIOKA JUNSUKE
IPC: C30B29/06
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a production unit for single crystal silicon and method for producing it, capable of affording single crystal silicon <=12×10<17> atoms/cm<3> or <=10×10<17> atoms/cm<3> is oxygen concentration with uniform axial oxygen concentration distribution. SOLUTION: Electric power to be inputted into the main heater 6 enclosing a quartz crucible 4 and an inversely truncated cone-shaped top heater 9 set up above the quartz crucible 4 is controlled so as to hold a melt 5 within a specified temperature range when the aimed signal crystal silicon 10 is to be pulled up. Coordinated use of the main heater 6 and the top heater 9 reduces the necessary calorific power of the main heater 6, resulting in reduction in the heat load applied to the quartz crucible 4 and the amount of oxygen leaching from the crucible 4 into the melt 5, thus affording the objective single crystal silicon low in oxygen concentration and uniform in oxygen concentration distribution. Besides, the single crystal silicon 10 can be imparted with the optimum thermal history.  Use of the above method by application of magnetic field affords the aimed single crystal silicon with lower oxygen concentration.

IPC: G11B20/18
Filed: 1987-11-06
Abstract: PURPOSE:To improve accuracy by adding a flag to the error of block data and change it into an erasure in accordance with the decoding condition of a block number. CONSTITUTION:At the time of reproducing, a signal by a reproducing head 31 passes through a switch 32, is demodulated by a demodulator 33 and after that, its jitters, etc., are absorbed by a time-axis correcting circuit 34. In C1 and C3 decoders 35, the error in a tape longitudinal direction is corrected by the C1 decoder and after that, block numbers BA1 and BA2 are corrected by the C3 decoder. When they are uncorrectable, a correcting processing is executed and the decoder 35 instructs a decoder 37 to execute the self-advance of the block number, to add the flag to the datum to be an error to which the flag is not added among the data of the block of the uncorrectable number and to make it into the erasure. When the numbers BA1 and BA2 are corrected, the above-mentioned instruction is not executed. Next, digital data are inputted to a deinterleave circuit 36 by using the numbers BA1 and BA2. The data are rearranged by the circuit 36, the correction detection of the error is executed by the decoder 37 and that is converted into an analog signal through a D/A converting circuit 38. Thus, the accuracy can be improved.

Patent JP-H02128155-A (JP)
Title: Oxygen sensor
Inventor: NURI KENJI
IPC: G01N27/419
Filed: 1988-11-07
Abstract: PURPOSE:To obtain a measured value of high reliability without lowering sensitivity in spite of long-time use by discharging the oxygen in a reference space to the outside by the oxygen pumping action of a solid electrolyte in a reference circuit. CONSTITUTION:In measuring the concn. of oxygen, voltage is applied to a solid electrolyte 1 at first by a DC power supply in a reference circuit A and the oxygen in a reference space 6 is discharged to the outside by the oxygen pumping action of the electrolyte 1. Thereafter, a switching element S is changed over to set a measuring circuit B to finish the application of voltage to the electrolyte B. Next, in the circuit B, since the concn. of oxygen in the space 6 is zero%, the difference in the concn. of oxygen with sample gas is generated and, therefore, the electrolyte 1 generates conc. cell action to generate electromotive force. This electromotive force is measured by a voltmeter V. The magnitude of this electromotive force is proportional to that of the concn. cell action and, since this cell action is proportional to the difference in the concn. of oxygen between the space 6 and the outside space, the concn. of oxygen in the outside space can be measured.
