Title: Production of polyfluoroalkyl esters and production of fluorine-containing acrylic copolymer
Inventor: YASUHARA HISAFUMI
IPC: C07C67/10
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To produce a polyfluoroalkyl (meth)acrylate at an advantageous installation cost while improving the yield of an ester-forming reaction, because a dehydration treatment is omitted by protecting water from entering the reaction system. SOLUTION: A polyfluoroalkyl iodide of the formula: CnF2n+1CH2CH2I (n is an integer of 2-26), and a metal (meth)acrylate (e.g. potassium acrylate) preferably in an amount within the range regulated so that the molar ratio thereof to the polyfluoroalkyl iodide may be 1.0-1.25 are inserted into a reactor, and subjected to an ester-forming reaction while regulating the water content in a reaction system so as to be 0.01-1.0 wt.% to provide the objective polyfluoroalkyl (meth)acrylate of the formula CnF2n+1CH2CH2OCOCX=CH2 (X is H or CH3). A fluorine-containing acrylic copolymer obtained by copolymerizing the obtained ester with an ethylenically unsaturated compound is excellent in stain-proofing properties, antistatic properties or the like, and can be used as a water- and oil-repellent agent, and a fiber-processing agent.

Title: Video signal output circuit
Inventor: ASAI SHIGEYA
IPC: G09G5/00
Filed: 1992-06-30
Abstract: PURPOSE:To use a crystal oscillator whose frequency is stable by switching analog signals, which are obtained by a D/A converter at the same time and as many as a specific number of pixels, at a speed corresponding to a dot clock frequency. CONSTITUTION:Digital image data stored in an image memory 10 are read out and converted from digital to analog to output an analog video signal of 500MHz in dot clock frequency. An oscillation output of 725MHz which is a quarter as high as the dot clock frequency is obtained from the crystal oscillator 13. Four D/A converters 12 are put in parallel operation by using the oscillation output as a clock signal and the four analog signals which are obtained in parallel are switched in order by an analog switch 14. Namely, those four analog signals are switched by the analog switch 14 at intervals of one nanosecond so as to arrange those four analog signals in series at intervals of 2 nanoseconds and obtain the video signal of 500MHz in dot clock frequency.

Title: Ultrasonic probe
Inventor: NAKAMURA HISASHI
IPC: A61B8/12
Filed: 1990-07-26
Abstract: PURPOSE:To facilitate insertion into a body cavity of a subject while achieving a higher ultrasonic diagnostic capacity by mounting two transducers at a hard- tipped part of a medium conduit as part to be inserted into a body cavity with one of the transducers being smaller in overall size than the other. CONSTITUTION:Requirement of l1>l2 is set with performance of a transducer 3 in preference to that of a transducer 4. Therefore, a portion to be occupied by the two transducers 3 and 4 can be reduced significantly, which achieves a smaller size of the hard tipped part 2 as whole accordingly. A deviation in the center axis between the transducers 3 and 4 can be reduced significantly as compared with the conventional type according to a relation of l1>l2. This makes the ultrasonic probe easy to swallow by a subject and allows a significant reduction in photographing position errors between section images of two dimensions orthogonal to each other as shown on an ultrasonic diagnosistic apparatus body as compared with the conventional type.

Title: Image formation device
Inventor: MIYAZAKI HIDETO
IPC: G03G21/00
Filed: 1990-07-26
Abstract: PURPOSE:To enable excellent image formation at all times even when a solenoid device which has relatively low performance is used by detecting the overheating state of the solenoid device and interrupting the image forming operation. CONSTITUTION:The current of the stepping motor 20 is converted by the resistance R1 of a detecting means 23 into a voltage VC, which is inputted to a 1st comparing means 28 and compared with a 1st reference voltage V1. The comparison result is inputted to a CPU 24 and when the voltage VC is higher than the 1st reference value V1, printing operation is carried on, but when the voltage VM is equal to or lower than the 1st reference value V1 (in case of a decrease in suctional force due to a rise in the temperature of a solenoid coil 20a), it is judged at the point of time whether the printing operation is in process or not and when the current printing operation is completed, the printing operation is interrupted to inform an operator of that through an operation display part 25. Consequently, even when the solenoid device which has relatively low performance is used, the image formation is securely carried out and the cost and size are reducible.

Abstract: PURPOSE:To protect the lining of a mixer from erosion due to starting materials for glass preheated to high temps. when the materials are mixed in the mixer, by feeding molten glass cullet to the mixer besides the starting materials to cover the lining of the mixer with the cullet. CONSTITUTION:When starting materials for glass are melted in a glass melting vessel 1 provided with regenerators 3, starting materials 9 such as silica sand, dolomite and limestone are preheated to 1,000 deg.C with waste combustion gas from the vessel 1, and starting materials 10 such as feldspar, soda ash and sodium sulfate are heated to 500 deg.C with said gas. The materials are weighed with weighing machines 14, 15, charged into a mixer 13 and mixed. At this time, the refractory lining of the mixer 13 is chemically burned out by active starting materials such as soda ash, shortening the endurance life of the lining and causing the contamination of the starting materials for glass due to the lining material. In order to prevent the burnout, molten glass cullet is simultaneously fed from a glass cullet preheater 11 to cover the lining of the mixer 13.
