IPC: C07C45/78
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a plant for purifying acrolein present in the gaseous mixture of acrolein, water, an acid and non-condensing maters. SOLUTION: This plant comprises a cooling column 1 having a means 2 for feeding the flow of a feed gas and a condensing apparatus 3, 3A and 3B having a means for feeding gas to the top of the cooling column 1.

Title: Electromotive extractor of liquid container
Inventor: TAMURA AKIRA
IPC: A47J41/00
Filed: 1990-08-04
Abstract: PURPOSE:To satisfy simplification of operation and outer figure by a method wherein an introducing passage is provided between a housing position aligned with an outer surface of a container body and an extracting position protruded from the outer surface of the container body, so that the passage can go out and retreat freely, and a driving mechanism to make the introducing passage go out and retreat and an operating means to operate the driving mechanism properly are provided. CONSTITUTION:Contained liquid is extracted automatically by an electromotive pump 44 through an introducing passage 31. When the introducing passage 31 is not used for extraction, the passage 31 is housed at a housing position aligned with an outer surface of a container body, making the outer surface of the container body smooth without any protruding and recess. Further the introducing passage 31 is protruded automatically by a proper operation of an electromotive mechanism by an ON-OFF operating means from the housing position to a protruded extracting position. That is, by a simple operation irrespective to the aligned state with the outer surface of the container body, the introducing passage 31 can be protruded to enable the extraction of the contained liquid. In addition, the introducing passage 31 is automatically retreated from the extracting position to the housing position by a proper motion of the electromotive mechanism by the ON-OFF operating means. Therefore, as the introducing passage 31 can be housed firmly irrespective to the shape and the like of the passage 31, both the extracting operation and the outer figure of a liquid container with an electromotive extractor can be simplified.

IPC: B65H54/56
Filed: 1981-12-21
Abstract: PURPOSE:To permit high speed rotation of a bobbin irrespective of bobbin material by allowing both ends of a bobbin holder to bear against a friction ring and a friction guide in the early take-up time to form a gap between a bobbin and a friction roller. CONSTITUTION:A bobbin holder 1 is constituted from a cantilever tubular support 3, a rotary shaft 4 and a bobbin inserted pipe 5 at the end. On the other hand, a friction roller 10 for rotating bobbins B1-B4 inserted into the pipe 5 is supported on both ends and provided on one end with a friction ring 11 contacting only the pipe 5 in the early take-up time for rotatably driving the pipe 5. On the other end, the friction roller 10 bears against a guide roller 12 supported rotatably in the end face of the bibbin holder 1. A friction guide 18 is  fixed. Thus, since a gap A is formed between the bobbin and the friction roller  in the early take-up time, the roller can be rotated with high speed irrespective  of the bobbin material so that even bobbins of plastics can be used. Also, this  gap is ehsured througout all bobbins.

Abstract: PURPOSE:To make it possible to perform operation without movement of workers and to reduce a space for installation, by changing the direction of rotation of a motor, which rotates an apparatus, according to the operation turning a turntable, and changing the positions of squeegee part and a holder part. CONSTITUTION:A holder part 6 and a squeegee part 8 are driven with the same motor for a surface plate 5, which can be rotated in the forward and reverse directions and fixed on a turntable 4, which is turned in one direction. The parts 6 and 8 are rotated in association with the rotation of a motor 9 through a pulley 14 having a one-way clutch. When the motor 9 is rotated in the reverse direction, the pulley 14 having the one-way clutch is also rotated. The rotation is transmitted to a shaft 16, and a pulley 15 is also rotated. Since the pulley 15 is intermeshed with the rack of a base plate 3, the turntable 4 is turned in the reverse direction with respect to the surface table 5 together. Thus, the squeegee part and the holder part can be positioned in front of a working operator readily. Thus, the working efficiency is improved, and an installation space can be made small.

Title: Wavelength multiplexed light transmission system
Inventor: ITO TOSHIO
IPC: G02F1/35
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a wavelength multiplexed light transmission system easy to manage wavelengths by letting each node transmit and receive an optical signal of a wavelength multiplexed group consisting of plural wavelengths, or letting it perform a batch wavelength conversion among the wavelength multiplexed groups. SOLUTION: In a wavelength multiplexed light transmission system using 16 wavelengths, the 16 wavelengths are divided into 4 groups A-D of 4 wavelengths each. To communicate between a node 101 and a node 105, the 4 wavelengths of the group D used between the node 101 and the node 102 are converted in batch into the 4 wavelengths of the group C by using a multiplexed wavelength batch conversion device. And they are transmitted to the node 102, a node 103, and a node 105. Since the wavelengths are not individually managed but managed in groups, the management of the wavelengths becomes easier. Moreover, plural wavelengths belonging to a prescribed wavelength multiplexed group are respectively made to be adjacent to plural wavelengths belonging to another wavelength multiplexed group, to perform the conversion with efficiency.
