Title: Bar width recognizing method
Inventor: NAKAMURA TATSUYA
IPC: G06K7/10
Filed: 1982-05-20
Abstract: PURPOSE:To improve the read precision of bar codes by obtaining a coefficient of distortion from the detected value of a bar printed at the center part of a bar code to basic width, and generating comparison data by the kinds of bars on the basis of the coefficient. CONSTITUTION:Distortion that information after photoelectric conversion has does not depend upon the number of modules of objective bars, but is constant and depends upon the kind of the bars. For this purpose, the coefficient of the distortion is calculated from the detected width of the bar printed in the center of the bar code to the basic width. Comparison data by the kinds of bars are generated from the coefficient of distortion and the detected width per module found from the whole of one character in order to obtain the numbers of modules of respective bars constituting the character, and the number of modules of each bar is recognized to read the bar code.

Title: Adsorbent for removing transuranium element and its manufacture
Inventor: MATSUMOTO SHIRO
IPC: G21F9/12
Filed: 1991-04-18
Abstract: PURPOSE:To obtain an adsorbent having a high rate of adsorption of transuranium elements from a radioactive waste solution. CONSTITUTION:A porous macromolecular carrier of a styrene-divinylbenzene copolymer having the property of swelling is manufactured under such a condition that a polymerization temperature becomes at least 50 deg.C to at most 80 deg.C, and by impregnating the porous macromolecular carrier with an organophosphoric acid extractant, an adsorbent for removing transuranium elements is obtained. The quantity of the organophosphoric acid extractant with which the porous macromolecular carrier is impregnated, is increased, because a polymerization temperature in the time synthesizing the porous macromolecular carrier forming the adsorbent is limited within the range of at least 50 deg.C to at most 80 deg.C in the method, and therefore the obtained absorbent indicates large adsorption capacity.

IPC: H03H3/04
Filed: 1980-06-27
Abstract: PURPOSE:To prevent oscillation characteristics from deteriorating owing to unnecessary oscillations by dividing an electrode, on one side of an oscillator composed of a piezoelectric plate polarized in the same thickness direction, into two. CONSTITUTION:A piezoelectric oscillator 1 consists of a rectangular piezoelectric plate, an electrode 4 formed on the counter main surface of the piezoelectric plate 2, and aplit electrodes 6 and 8, and the piezoelectric plate 2 is polarized in the same thickness direction.

Abstract: PURPOSE:To accurately determine the frosting condition so as to improve the operation efficiency by providing a heat exchanger temperature sensor, an ambient air temperature sensor, a humidity sensor, an absolute humidity operator means and a comparator means, and determining the frosting condition for defrosting operation based on the detection of a fact that the temperature as detected by the outside heat exchanger temperature sensor is sub-zero and the comparative result by the comparator means.

The determination is made under the condition that the temperature measured by a heat exchanger temperature sensor 7 is sub-zero, and the absolute humidity is found larger than the saturated water vapor volume for afore-said temperature when they are compared. The amount of frosting from the start of frosting is determined by performing a calculation from the difference between the absolute humidity and the saturated water vapor volume relative to the temperature of the outside heat exchanger as well as the temperature of the outside heat exchanger, and when it is determined that the frosting exceeded the predetermined level, the defrosting signal is outputted. In this manner, the determination of starting the defrosting operation can appropriately be made under any condition.

Title: Head position controller for disk storage device
Inventor: KAWAHARA YUJI
IPC: G11B21/10
Filed: 1987-04-09
Abstract: PURPOSE:To reduce the probability of occurrence of reading errors or writing errors which cause reading errors, by discriminating execution of head position correction after discriminating whether head position movement is performed or not and executing corresponding head position movement and correction against plural disk surfaces. CONSTITUTION:Depending upon whether or not the number of track intervals of accessing position designating data is zero, a 1st discriminating means 60 discriminates whether head position movement is necessary or unnecessary and outputs a signal when the means 60 discriminates it necessary. A head moving means 30 is driven in accordance with the signal and head movement is controlled so that the number of track intervals can become zero. When the means 60 discriminates it unnecessary, a 2nd discriminating means 70 discriminates whether head position correction is necessary or not depending upon whether a designated head number is equal to the previous one or not. When the means 70 discriminates it necessary, the head position is corrected through a head position correcting means 40 and off-track detecting means 50 and the head is put on the track. Therefore, probabilities of occurrence of reading errors or writing errors which cause reading errors of heads corresponding to plural disk surfaces can be reduced.
