Filed: 1986-04-16
Abstract: PURPOSE:To suppress an off-track of a servo head at a half or below the maximum off-track by using the arithmetic mean of the off-track as a reference off-track so as to apply the positioning. CONSTITUTION:A data head 2 might be subjected to off-track from a reference position obtained from a servo head 3 due to the temperature gradient of a rotary storage medium 1 and a head supporting arm 4.

Title: Optical information recording medium
Inventor: KUNITOMO HARUO
IPC: G11B7/2433
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To obtain a DRAW type medium having high storage stability for data and to obtain a reloadable medium in which information can be repeatedly recorded and erased by forming a dielectric layer essentially comprising a specified material for the medium having a phase transition type optical recording layer and the dielectric layer. SOLUTION: A dielectric layer on a substrate is formed by using a mixture of SiO2 and silicon carbide having high heat resistance and adhesion property with a phase transition type recording layer so as to improve a conventional protective film comprising an SiO2 single material. As for the protective film, a dielectric material containing >=50mol% of these compds. is used. If the amt. is lower than that, the effect to prevent deformation of the substrate or the recording film is not sufficient and the film is not effective as a protective layer. The amt. of SiO2 is controlled to 10 to 90mol% of the whole dielectric layer. If the proportion is lower than 10%, desired characteristics can not be obtd. If the proportion is higher than 90%, the coefft. of optical absorption increases.  Moreover, by controlling the proportion of silicon carbide to 5 to 90mol% of the entire dielectric layer, desired characteristics can be obtd. The compd. used is a heat-resistant compd. having heat resistance against >=1000 deg.C temp. and is enough optically transparent.

Filed: 1989-04-07
Abstract: PURPOSE:To easily monitor an optical transmission line by modulating stimulating light with a pulse pattern having a shorter period than the relaxation time of a stimulating carrier and making the light incident on an optical fiber, and finding the time correlation between the pulse pattern and back scattered light. CONSTITUTION:This method is provided with a circuit 5 which is driven by a random pulse pattern generator 12, a directional coupler composed of a half- mirror, a photodetector 13, a correlator 14, and a delay circuit 15. Then the light from a stimulating light source 6 is modulated with the random pulse pattern of the generator 12 and made incident on the Er-doped optical fiber through the coupler 11 and a multiplexing demultiplexing circuit 4 together with signal light. Back scattered light at each point of the fiber due to the random pulse pattern passes through the circuit 4 and coupler 11 and is converted by the light receiving device 13 into an electric signal, which is inputted to the correlator 14 and collated with the random pulse pattern through the circuit 15. Then a back scattering waveform is obtained by the delay time sweeping of the circuit 15. Consequently, the loss and fault point of the transmission line can be detected and the optical transmission line can easily be monitored.

Title: Read and write control system of bubble memory
Inventor: MINEMURA TOSHIMITSU
IPC: G11C11/14
Filed: 1983-05-18
Abstract: PURPOSE:To shorten an access time by preventing a defective loop data from being inputted to an RAM of a sequencer. CONSTITUTION:A shift register 50 outputs a write data WD1 by 1-bit each whenever a clock CLK is inputted. For instance, when a write data is 11011100-, and a defective loop data is 11101111-, the fourth clock CLK is stopped by a function of a NAND gate G1, therefore, a write serial WD2 becomes 110011100-, and it passes through a major loop 42 and is written all at once in each minor loop 31, 32-. A shift register 52 closes the NAND gate G1 when the fourth loop DL from an ROM26 is ''0''. As a result, if a read-out serial data RD1 is 110011100-, a read-out parallel data RD2 becomes 11011100- obtained by eliminating No.4 and putting close No.5 and thereafter to 1-bit before, and becomes equal to the write data.

Title: Optical reception circuit
Inventor: YAGYU MIKITO
IPC: H04B10/564
Filed: 1988-04-11
Abstract: PURPOSE:To suppress the decrease in a reverse bias voltage of an avalanche photodiode(APD) against the increase of a photoelectric current by clipping a voltage drop across a protection resistor by a forward voltage in an optical reception circuit provided with the protection resistor protecting the APD. CONSTITUTION:A high voltage generating circuit 9 is controlled by a gain control circuit 8 at a photodetection area over a gain switching point and its output voltage is changed. A current I1 flowing to a diode 10 is much larger than a current I2 flowing to the protection resistor 1, resulting that the voltage V of a parallel circuit comprising the diode 10 and the protection resistor 1 is very small. Thus, the voltage from a high voltage generating circuit 9 is clipped to the voltage drop by the forward voltage component only of the diode 10 connected in parallel with the protection resistor 1 with respect to the increase in the photoelectric current attended with the average photoelectric current and given as a reverse bias voltage of the APD. As a result, the decrease in the reverse bias voltage of the APD and the reduction in the multiple factor M of the APD are suppressed.

Title: Output correction method for oxygen analyzer
Inventor: MURASE TAKAO
IPC: G01N27/419
Filed: 1993-03-23
Abstract: PURPOSE:To highly accurately correct output from an oxygen analyzer even if the pressure of exhaust gas fluctuates significantly by determining a fluctuation index of gas pressure according to a regression function of the combustion exhaust gas pressure and the fluctuation index of exhaust gas pressure. CONSTITUTION:A gas pressure fluctuation index B of an oxygen analyzer is determined under each pressure from an output Ip of the oxygen analyzer obtained through actual measurement of a sample gas having known components under different combustion gas pressures P. The index B is then corrected based on pressure dependence by approximating the regression function of the values of gas pressure P with a primary function. Output Ip from the analyzer obtained through actual measurement of variable gas pressure P is then corrected with the corrected index B thus determining a corrected output I'p of gas pressure. This method can prevent occurrence of measurement error due to pressure fluctuation substantially perfectly when the fluctuation of gas pressure P is 2kg/cm<2>G or below and suppresses occurrence of error effectively even when the pressure fluctuation is 3kg/cm<2>G thus providing a highly accurate output Ip which is not susceptible to the fluctuation of exhaust gas pressure.

Abstract: PURPOSE:To sufficiently suppress the relative displacement of an external core body relative to external covering bodies upon heat cycle by bonding respective external covering body units with an elastic body of low Young modulus when the external covering body units containing shades made of a synthetic resin are produced an a highly rigid insulative core body. CONSTITUTION:Hood containing external covering body units 31 to 33 made of a synthetic resin composition (such as polyethylene) excellent in tracking resistance and arc resistance are adhered to a highly rigid insulative core body 2 (such a FRP) via an adhesive or a greese so as to form a composite insulative body. In this case, an elastic body 4 (such as a rubber material) whose Young modulus is sufficiently lower than that of the external covering body units 31 to 33 is provided between respective hoods containing external covering body units 31 to 33 so as to bond them. Accordingly, even if it is long, the displacement of the external covering body units 31 to 33 relative to the core body 2 can be suppressed, so that a composite insulator with excellent insulative strength can be provided.
