Title: Cryogenic apparatus
Inventor: TAKANO HIROHISA
IPC: F17C13/08
Filed: 1984-07-12
Abstract: PURPOSE:To considerably reduce the amount of external heat infiltrating a cryogenic container, by providing hollow legs for supporting a vacuum vessel so that they are communicated with the vacuum vessel, and supporting the cryogenic container by means of supports which are respectively provided in the hollow legs in such a manner that a spacing is provided between each support and the side walls of the corresponding leg. CONSTITUTION:Legs 6 for supporting a vacuum vessel 4 have a pipe-like configuration. The upper part of each leg 6 is opened inside the vacuum vessel 4, and the lower part thereof is hermetically closed by a pedestal 7, whereby the inside of each leg 6 is kept at a vacuum. A support 8 is provided inside each leg 6 and secured to the associated pedestal 7 so that the support 8 extends upwardly with a spacing provided between the same and the side walls of the leg 6. The upper part of the support 8 is fixed to a seat 9 secured to the side of a cryogenic container 2. Each support 8 is formed so as to have a strength which enables it to endure the weight of the cryogenic container 2 and a load applied thereto when an earthquake occurs. Since the supports 8 extend not only through the vacuum vessel 4 but also through the respective legs 6, the length of the supports 8 can be made, e.g., two or more times as longer as that in the conventional supports. The amount of heat externally entering the cryogenic container 2 by heat conduction of the supports is inversely proportional to the length of the supports. The refore, if the conducting portion of each support 8 has the same material and the same cross- sectional area as those of the conventional support, the amount of heat infiltrating the cryogenic container can be made less than a half as compared with that in the case of the conventional apparatus.

Title: Bubble memory device
Inventor: OOTA HIROBUMI
IPC: G11C19/08
Filed: 1979-11-07
Abstract: PURPOSE: To increase the parallel degree of the magnetic adjuster plates which are provided in opposition to each other, by providing the level-difference part at the peripheral parts on the upper and lower faces of a molded device to give the upper  and lower positioning to the magnetic adjuster plates.  
     CONSTITUTION: The bubble memory device is formed by fixing the magnetic adjuster plates on the upper and lower faces of a molded device via the adhesive. The level-difference parts 4c and 4d are provided at the peripheries on the upper and lower faces 4a and 4b of the molded device. In case the magnetic adjuster plates 7a and 7b are fixed onto the faces 4a and 4b of the molded device via the adhesive 9, the parallel degree between the plates 7a and 7b is decided by the parallel degree between the parts of 4c and 4d since the adhesive 9 exists in the gap between the plates 7a/7b and the faces 4a/4b. Thus the parallel degree between the  plates 7a and 7b is increased greatly in comparison with the parallel degree of  ±0.03 obtained by the normal molding.

Title: Zoom lens for definite distance
Inventor: OSADA HIDEKI
IPC: G02B15/16
Filed: 1993-06-15
Abstract: PURPOSE:To obtain a zoom lens for definite distance capable of excellently compensating magnification chromatic aberration over a wide range without versatile use of a glass material having abnormal dispersability by making a lens on the most objective side of a first group a joined lens of a positive refractive power. CONSTITUTION:This lens has a first group of a negative refractive power and a second group of a positive refractive power in order from an enlarging side and the spacing between the first group and the second group is changed by varying the power. In this case, by making a first lens a joined lens having a positive refractive power and subjecting to an achromatic processing in the joined lens, the magnification chromatic aberration is excellently compensated over the whole zooming area. Also, by making the enlarging side of the joined surface of the joined lens a concave surface, the compensation of off-axis light beam is facilitated. Namely, since an incident angle to recessed surface on the enlarging side becomes larger than that of a convexed surface for an off-axis light beam, the compensation of the off-axis light beam is easily performed. Since the joined surface has a negative refractive power, the compensating effect of the magnification chromatic aberration is enhanced as it goes farther to off-axis.

Title: Character detecting and segmenting device
Inventor: OOTA NAOKI
IPC: G06V10/10
Filed: 1981-09-11
Abstract: PURPOSE:To read postal code numbers at unfixed positions by forming a mask for every character from a pattern signal obtained by scanning a prescribed area optically, and putting respective masks in blocks according to their lines and pitches and discriminating and segmenting only characters. CONSTITUTION:The 1st scanning part 11 scans in a visual field on postal matter P and then performs photoelectric conversion to obtain a pattern signal. From the pattern signal, a character line detection part 12 forms an X and an Y mask by projection in directions X and Y to select a block of masks suitable as address information from each line signal extracted by the mask signals, and then sends it to the 2nd scanning part 13. The 2nd scanning part 13 scans the selected block and performs photoelectric conversion to obtain a pattern signal, which is sent to a character detecting and segmenting device 14. This device 14 discriminates numbers, KANJI (Chinese character), and postal marks, with every block, to select only the numbers, which are sent to a character recognition part 15, where they are discriminated by being compared with reference number patterns. Thus, postal code numbers at unfixed positions are extracted and read.

Title: Image dot converting method
Inventor: SATOU MASATAKE
IPC: G03F5/14
Filed: 1981-09-10
Abstract: PURPOSE:To perform dot separation clearly from highlight parts to shadow parts of an original picture, by adding reflection density within a specific range to the entire surface of the original picture when exposing the original picture through a dot separation screen in contact. CONSTITUTION:A dot separation screen 37 is brought into contact with a desired part of an original picture 34 with successive gradations to perform exposure, thereby dot-separating the desired part of the original picture 34. In this case, a filter 18 with 0.2-0.5 density is superposed upon the original picture 34 to add 0.2-0.5 reflection density to the entire surface of the original picture 34. Consequently, the ratio of the density range from highlight parts to shadow parts of the original picture is decreased adequately to obtain a photoengraved plate, which is dot-separated by the exposure to a satisfied extent over the entire surface from the highlight parts to the shadow parts to perform image conversion, easily by performing the image conversion once.
