Title: Optical character reader
Inventor: NANBA HIROMI
IPC: G06K9/20
Filed: 1982-05-11
Abstract: PURPOSE:To read a text entered in free format as it is, by detecting the leftmost end character position of the text, and entering a space symbol or indent symbol to the top of the read result of each line on the basis of the detected position. CONSTITUTION:A recognition part 22 makes a scan in a line pattern memory 23 to detect a character entered into a document at its left end and finds the X coordinate value of the character based upon the left end of the document to store the X coordinate in a working memory 27 through a control part 26. Then, the recognition part 22 recognizes character patterns in the line pattern memory successively from the left and stores the results in a buffer memory 24. The control part 26, on the other hand, finds the minimum value among X coordinates of each line stored in the working memory 27 and also adds a calculated number of space symbols to the top of the recognition result of each character line stored in the buffer memory 24. Then, the recognition result of the buffer memory 24 is outputted to a work processor through an interface 25.

Title: Deaerating and hermetic sealing method of metal capsule in hot hydrostatic pressing method
Inventor: HONMA KATSUHIKO
IPC: B22F3/02
Filed: 1979-06-19
Abstract: PURPOSE: To sufficinetly maintain the degree of vacuum at the HIP treating and improve the yield of products by screwing and intermeshing the plug formed by hard material into a deaerating pipe, and melt-sticking both thereby integrating the same.  
     CONSTITUTION: When the inside of a capsule 1 and vacuum vessel 12 reaches the specified degree of vacuum, a plug 8 is screwed and fitted to a deaerating pipe 3. This plug 8 is formed by the material harder than the material of the deaerating pipe 3 and its edge 7 intermeshes with the tapered part 7 of the deaerating pipe 3, thus even if the vacuum vessel 12 is removed, the inside of the capsule 1 is perfectly hermetically sealed, whereby the initial degree of vacuum is maintained. Circumferential welding grooves 11, 11' are beforehand formed to the top end weld zones of this deaerating pipe 3 and plug 8, and are subjected to circumferential welding 9 by MIG welding or CO 2  welding, whereby the deposited metal is formed. This method eliminates the fear for deaeration insufficiency and hermetic selaing defect, and stabilizes the quality of the HIP product.

Title: Eddy current type flow velocity meter
Inventor: IKEMI MOTOYOSHI
IPC: G01P5/08
Filed: 1981-05-22
Abstract: PURPOSE:To measure the flow velocity of various conductive fluids free from from effect of zero-point variation by synchronously rectifying differential signals from two detection coils with a signal related to a sum signal thereof. CONSTITUTION:An output of an a.c. signal generator 40 is applied to an exiting coil WEX, outputs of detection coils WD1 and WD2 are separately fed to amplifiers 104 and 105. The amplifier 104 computes a sum signal e3 concerning the temperature of a fluid to be measured from the outputs while the amplifier 105 computes a differential signal e4 concerning the flow velocity of the fluid therefrom. The signal e3 is converted 108 into a square wave signal e7 to synchronously rectify 109 the diferential signal e4. The differential signal e4 is rectified 110 to compute 114 a difference from the synchronously rectified output and applied to a divider 116. On the other hand, a signal e7 is converted 111 into a sine wave signal e8 and the output of a generator 40 is synchronously rectified 113 with a signal e13, converted 106 into a square wave to determine a difference from a rectified signal 112 of the signal e8 which is applied to the divider 116 as denominator. Thus, only the signal concerning the flow velocity of the fluid measured can be obtained.

     CONSTITUTION: This method for purifying acrylic acid by fractionation comprises the steps of: purifying acrylic acid by a combination of dynamic crystallization K-1 with static crystallization K-2 in a plurality of steps ; further purifying the residue from the dynamic crystallization by static crystallization; and returning the resultant acrylic acid to dynamic crystallization. Acrylic acid having an impurity content up to 20% (wt.), pref. up to 10%, is fed to the step of dynamic crystallization, and purification is carried out by crystallization/dissolution cycle in two or more steps. The purified crystal is recovered from the highest purity step, and, also in the lowest purity step, the impurity concn. of the residue is lowered to up to 30%, pref. 10 to 25%. The residue is fed to the step of static crystallization, and purification is carried out in at least one step to conduct enrichment until the impurity concn. of the residue reaches about 70%. The residue is separated from the purification process, and the crystal material from the highest purification step in the static crystallization is returned to dynamic crystallization step.

Title: Magnetic field generating device
Inventor: ANDO HIDEO
IPC: G11B11/105
Filed: 1987-03-31
Abstract: PURPOSE:To improve the magnetic generation efficiency as well as a heat radiation effect and to elevate the magnetic utilization efficiency by forming a slender magnetic coil which is wound at a magnetic core part and by making a magnetic flux discharge part and the magnetic core part have structures comprising stepped parts. CONSTITUTION:When a magnetic coil 32 is energized by supplying a current, magnetic flux is supplied from a magnetic core part 34 to a magnetic flux leading out part 37 through a coupling part 38 and is discharged toward a region where the light beam of a photo- electromagnetic recording film 24 can be irradiated from a magnetic flux discharge plane 37A located at a lower plane of the magnetic flux leading out part 37. Then, the photoelectro- magnetic recording film 24 is exposed to magnetic flux that is perpendicular to its plane. Magnetic flux which is passing through its film 24 enters into a yoke 39 through a space and is feedback to the magnetic core part 34 which is magnetically and mechanically coupled to the yoke. In such a structure, the magnetic coil 32 is so slender that a great magnetomotive force is obtained by less electricity consumption and its heat radiation effect is also excellent. Since the magnetic flux leading out part 37 and the magnetic core part 34 have stepped parts, its configuration allows the magnetic flux discharge plane 37A to approach sufficiently an information recording medium 20 and the magnetic utilizastion efficiency can be elevated.
