Title: Method for separating and purifying methylene chloride and n-hexane
Inventor: KOBAYASHI YASUSHI
IPC: C07C7/10
Filed: 1982-10-25
Abstract: PURPOSE:To separate both components in a mixture consisting of methylene chloride and n-hexane in a reusable purity, by distilling the above-mentioned mixture or further containing water added thereto, extracting the resultant distilate fraction with ethylene glycol, and distilling the resultant extract solution. CONSTITUTION:Water is added to a mixture consisting of methylene chloride and n-hexane, and the resultant mixture is distilled in a distillation column 1, and then the resultant distillate fraction is extracted in an extraction column 8 to distill the resultant extract solution in a distillation column 12. Alternatively, the above-mentioned mixture is directly extracted with ethylene glycol to distill the above-mentioned extract solution and separate respectively the methylene chloride in the distillate and n-hexane in the bottom residue. The above-mentioned mixture is often discharged as a solvent waste liquor in preparing medicines or agricultural chemicals. Since the methylene chloride and n-hexane are azeotropic solvents, it is difficult to separate them by the usual distillation. Therefore, they have been discarded usually without utilization. The above- mentioned treatment permits the reutilization thereof.

Abstract: PURPOSE:To improve the degree of freedom of the design by providing symmetrically two sets of differential amplifiers of CMOS constitution and extracting an output from the amplifiers via a push-pull circuit so as to improve the distortion factor characteristic at a low voltage operation. CONSTITUTION:A differential input stage 12 comprising an N-channel MOSFET having a current mirror load 11 and a differential input stage 14 comprising a P-channel MOSFET having a current mirror load 13 are provided symmetrically. Then a signal from the differential input stage 12, 14 is extracted through an output stage 17 of push-pull constitution. When a signal is fed to inverting and non-inverting input terminals 2a, 2b of the circuit, positive/negative half cycles of the input signal are amplified respectively by the differential amplifiers of the input stages 12, 14, applied with push-pull amplification at the output stage 17 and extracted at an output terminal 4. Since the distortion is reduced by the push-pull operation and each differential amplifier has only to handle the half cycle of the input signal, the degree of freedom of the design is improved.

Abstract: PURPOSE:To prevent a tape from flawing and to reduce a noise by providing a plural number of claw members on the circumferential surface of a reel hub engaging member at isometric intervals, making the claw members freely displacible in the radial direction of the reel hub engaging member and allowing the claw members to move outwardly in the radial direction by a centrifugal force at the time of high speed revolution. CONSTITUTION:A reel base 1 is axially supported by a reel base shaft 4 and driven by a reel base driving means. A reel hub 23 is driven by engaging the plural number of the claw members 12 provided on the reel hub engaging member 10 of the reel base 1 with the plural number of recessed parts 25 formed in a center hole of the reel hub 23. The claw members 12 is freely displacible in the radial direction of the reel hub engaging member 10, and usually regulated by an elastic force of an elastic member 14 in the direction of the center axis of the reel base 1. When a magnetic tape 26 is traveling at high speed, i.e., the reel base is revolving at high speed, the claw members 12 are displaced outwardly in the radial direction of the reel hub engaging member 10 by the centrifugal force against the elastic force of the elastic member 14, so as to hold the inner circumferential wall of the center hole of the reel hub 23 by a pressing force. By this method, the tape can be prevented from flawing and the noise reduction can be contrived.

Abstract: PURPOSE:To copy and reproduce part of a black image in another color by erasing a latent image part corresponding to an image area in a color-separated latent image by an erasing method, and reproducing a part corresponding to an image area in a copy image in a conversion color. CONSTITUTION:An original O is placed on glass 16 and then the peripheral surface of a photosensitive body 10 is charged uniformly and electrostatically. Then, a red filter F1 is placed in an optical path of exposure and when the peripheral surface part reaches an exposure part, the original O is lighted and scanned by a lamp 140 and a plane mirror 141 in one body to form a color- separated latent image of red on the photosensitive body 10. A microcomputer turns on LEDs of an eraser 18 to erase the latent image part corresponding to the part within a color-conversion area. When a blue filter F3 is used, a visible image of yellow is transferred and then transfer paper S is separated from a holder 28 and discharged from a machine after the color visible image is fixed. Consequently, some part in a neutral image is reproduced in another color and the color-converted part is emphasized, thereby expanding the functions of a color copying machine.

Filed: 1987-07-28
Abstract: PURPOSE: To achieve a higher heat exchange efficiency in an evaporator by providing orifices respectively at a plurality of holes to equalize the distribution of a refrigerant gas and a liquid. CONSTITUTION: This shunt 8 is constituted of an inlet hole 14 and a plurality of outlet holes 15 branched off the inlet hole 14. An expansion valve communication line 7 communicating with an expansion valve 6 is connected to the inlet hole 14. An orifice 18 is provided at each of the outlet holes 15 while pipelines 9a-9d communicating with an inlet of an evaporator 10 are connected thereto. The diameter (d) and the length 1 of the orifices 18 are determined so that when a pressure difference is represented by P between a saturation pressure of the refrigerant at which the refrigerant liquid expanded under a reduced pressure by the expansion valve begins to be vaporized and the saturation pressure of the refrigerant at the inlet of the evaporator, the total resistance of all the orifices 18 is almost larger than the pressure difference P.  This enables equalization of the proportion of the gas and the liquid in the shunt of the refrigerant to the plurality of pipelines 9a-9d thereby achieving a uniform heat exchange with the pipelines.
