Title: Reader for character and picture signal
Inventor: TAKASHIMA MASATAKE
IPC: G11B7/24091
Filed: 1982-03-05
Abstract: PURPOSE:To reduce interarray movement and to perform high-speed data access, by arraying pit groups in a radius direction, and allowing a reader to reciprocate in the radius direction to read respective pit groups. CONSTITUTION:Light from a semiconductor laser 40 is passed through a polarization prism 42, quarter-wavelength plate 45, and lens 46 and polarized by the quarter-wavelength plate 45 to illuminate pits (not shown in a figure) of an optical disk. Reflected light from each pit is polarized again through the lens 46 and quarter-wavelength plate 45, and reflected by reflecting surfaces 44 and 43 of the polarization prism 42 to reach a photodetecting element 41. In this state, a piezoelectric element 48 is applied with a signal with a proper period (e.g. Sin3theta) to oscillate, and its oscillation is transmitted to a tuning-fork oscillator 47 to allow the laser 40, photodetecting element 41, polarization prism 42, quarter-wavelength plate 45, lens 46, etc., to reciprocate in the radius direction. Therefore, laser light passed through the lens 46 also reciprocates in the radius direction to scan pit groups one after another, thus reading data.

Title: Formation of latent image by polychromatic electrophotography
Inventor: KANEDA MASAYUKI
IPC: G03G15/01
Filed: 1983-03-07
Abstract: PURPOSE:To improve the granularity and color reproducibility of a polychromatic picture by providing the 2nd electrostatic charge process before a developing process after image exposure, and varying a leveling potential of each color between the white ground potential of an original and the potential of picture density to be reproduced. CONSTITUTION:The 2nd electrifier 3 is arranged between an image exposure station 2 and developing machines 4a-4c for three kinds of toner. When a DC constant voltage corotron is used as the 2nd electrifier 3, the leveling voltage VL is set between the potential VBG of the white ground part and the voltage Vn to be reproduced. Consequently, the potential of the white ground part rises up to V1 and the potential Vn of the density part rises up to Vn'. Namely, the unevenness of a surface potential pattern is leveled from a state shown by a broken line to a state shown by a solid line to reduce the intensity of a fringe electric field and also reduce the influence of edge effect, improving the granularity. Toner T is developed uniformly in proportion to the picture density to improve the color reproducibility.

Title: Differential amplifying circuit
Inventor: IRIKURA SHIYOUGO
IPC: H03F3/45
Filed: 1983-03-07
Abstract: PURPOSE:To minimize the offset voltage and also to avoid the deterioration of frequency characteristics under control of a load current, by using a circuit which extracts a part of the current flowing through a load and bypasses an input differential transistor. CONSTITUTION:The differential outputs Vout1 and Vout2 are obtained from a connection node N1 between a resistance Rc1 and an input differential transistor TRQ1 and a connection node N2 between an Rc2 and a TRQ2 respectively. Then variable constant current sources 2a and 2b are provided between the nodes N1 and N2 and the power supply voltage VEE respectively. A part of the current flowing through load resistances Rc1 and Rc2 is extracted to the voltage VEE from the nodes N1 and N2 after bypassing the TRQ1 and Q2. Thus the currents ic1 and ic2 flowing through resistances Rc1 and Rc2 can be increased or decreased without varying the currents i1 and i2 flowing to TRQ1 and Q2. As a result, the offset voltage Voff can be minimized with an even level of voltage drop between resistances Rc1 and Rc2 despite the variance of the load resistance and transistors.

Title: Abnormal temperature detector for insulating apparatus using gas
Inventor: OOTA TERUO
IPC: G01R31/12
Filed: 1981-03-11
Abstract: PURPOSE:To detect the abnormal temp. elevation of a juncture of high voltage conductors and to prevent serious accidents by providing a vacuum vessel of which the outside surface is broken by a needle when it is buckled by a pressure rise near said juncture, and detecting the leaking sound of the gas sealed therein with an oscillation detector. CONSTITUTION:Gaseous sulfur hexafluoride 2 is packed in a sealed metallic vessel 1, and a vacuum vessel 5 having a needle 7 is placed near the tulip contact 3 of high voltage conductors 4, 4'. An oscillation detector 6 is fitted to the outside surface of the vessel 1. If with this constitution the contact between the contact 3 and the conductors 4, 4' goes defective, the pressure of the gas 2 is increased by the abnormal temp. elevation owing to an increase in the electric resistance of that part, by which the vessel 5 is buckled and deformed, then a hole is pierced by the needle 7 and through this hole the gas 2 enters the inside of the vessel 5 and produces the leaking sound which is detected with the detector 6. Thereby, the abnormal temp. elevation of the juncture is detected in an early time and serious accidents are prevented.

Filed: 1994-03-07
Abstract: PURPOSE:To certainly estimate the strength of coke with high accuracy by calculating the weighted mean of the characteristic evaluation index and average max. reflectivity calculated from the fluorescent spectrum characteristics of the compositional components at every raw material coal and the dispersion of the characteristic evaluation index and average max. reflectivity of coke raw material coal. CONSTITUTION:Fluorescent spectrum characteristics are measured under a constant condition at every compositional components of coal and a fluorescence relative intensity ratio I index at wavelengths of 800 and 550nm is calculated therefrom as a characteristic evaluation index. There is strong correlation between the weighted mean of the characteristic evaluation index and average max. reflectivity and coke strength and the calibration curve showing this correlation is preliminarily calculated experimentally. By using this calibration curve, coke strength can be accurately estimated. Further, the dispersion degree of the characteristic evaluation and the average max. reflectivity calculated at every coal to be compounded also correlates with coke strength. Therefore, by adding the dispersion of the characteristic evaluation index and the average max. reflectivity to calculation, the strength of coke can be estimated with high accuracy.
