Title: Optical recording medium
Inventor: NAGINO KUNIHISA
IPC: B41M5/26
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To attain the reducing of a crosstalk amount and a cross erasure without providing a special optical system and a signal processing circuit by making the reflectance of the crystallization state of a mirror part to be within a prescribed range. SOLUTION: An optical recording medium is constituted so that a recording sensitivity is high, the contrast of a signal is high and also the reflectance of the crystallization state of the mirror part is larger than 15% and is not larger than 35%. When the reflectance of the crystallization state of the mirror part is larger than 35%, the irradiating power of a light performing a recording and an erasing becomes insufficient and the recording becomes difficult in a high-speed revolution and the crosstalk from the recorded part of adjacent tracks is increased. Moreover, when the reflectance of the crystallization part is not larger 15%, since the difference of reflectances between the recorded mark and a non-crystallization part is small, the signal contrast at the time of reproducing becomes small.  Here, the mirror part where grooves and pre-pits are not formed is called the mirror face part. Further, it is desirable that the reflectance of the non-crystallization part of the mirror part is not larger than 10%.

Title: Decomposition of chlorate salt in saline solution
Inventor: MIYAGAWA TAKASHI
IPC: C01D3/14
Filed: 1981-05-18
Abstract: PURPOSE: The chlorate salt in a saline solution is decomposed with hydrochloric acid as the concentration of hydrochloric acid in the solution is kept above a specific value, thus permitting the decomposition of chlorate salts under unhibition the formation of chlorine dioxide gas.  
     CONSTITUTION: When chlorate salts in a saline solution is decomposed with hydrochloric acid, the concentration of hydrochloric acid is kept above 150g/l in the solution to permit the docomposition of chlorate salts without formation of chlorine dioxide gas. Especially, in the electrolysis of alkali chloride to produce alkali hydroxide except the diaphragm method, the slight improvement in the dechlorination process for the circulated saline solution lowers the concentration of chlorine dioxide in the recovered chlorine gas to such a level as the recovered chlorine can be mixed with the anode chlorine. Further, even when the recovered chlorine is used to produce alkali hypochlorite, this process is advantageous, because it needs no facility for treating chlorine dioxide gas.

Title: Method of driving liquid crystal element
Inventor: TANAKA TAKAAKI
IPC: G02F1/133
Filed: 1988-03-29
Abstract: PURPOSE:To enable high-gradation display without having unequalness in the quantity of transmitted light and to prevent the deterioration of the liquid crystal element by averting the continuous impression of the voltage pulses for selecting the display contents of the element in the same polarity direction within the non-selection periods, providing an erasing period to said periods and decreasing the average value of the DC components to be impressed to the liquid crystal element to zero. CONSTITUTION:The signal electrode waveforms varying according to the display contents are impressed in the non-selection period t12, t22, t32, t42, but the continuous impression or the continuous impression via zero of the voltage pulses of the same polarities like signal electrode waveforms 202a, 202b does not arise. A pair of AC pulses + or -V4 of the absolute value larger than the saturation value of the liquid crystal element are impressed on the scanning electrodes in the non-selection periods t17, t27, t37 and t47. The element is off regardless of the contents of the selection periods in these periods. The non-selection periods t18, t28, t38, t48 are respectively the periods when the DC components generated in the selection periods t11, t21, t31, t41 are removed. The high-gradation display is thereby enabled and the deterioration of the element is prevented.

When the guide pole mechanism 5 comes to a loading position, the supporting plate 50 returns by turning clockwise to bring the erasing head 23 and impedance roller 24 into contact with a tape 4. The head 23 and roller 24 are fitted on one supporting plate 50 and the fulcrum of rotation of the supporting plate 50 is placed at a cassette side, so that while the structure is simplified, the range of the turning angle of the supporting plate 50 is made narrow.
