Title: Manufacture of catheter balloon and catheter
Inventor: TROTTA THOMAS N
IPC: A61F2/958
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To enable to place a stent appropriately in human body by stretching a tube part to a radius direction so a to receive a process hardening and then stretching it longways until it is induced with an enlarged molecular orientation longways and putting this tube in the human body as a part of a catheter. SOLUTION: A part of a tube 10b made of plastic material having a character to stretch in two axes is heated by using a heater 14 forming a center 19 to heat up a center 18a of a balloon 18 a little more warmer than heating up its end 18b. Thus, the yield value of the plastic used for the tube 10b is lowered. Next the inner shell 16 is pressed by a mold 17 so as to obtain a supplementary balloon by restricting the expansion of the balloon and impart the enlarged molecular orientation expanded in the axes directions to the balloon 18. Then the tube part 10b is stretched longways to narrow the balloon 18 and to make it thinner, and the tube is put in the human body as a part of the catheter.

Filed: 1987-03-27
Abstract: PURPOSE:To decrease a difference in display luminance in respective divided regions by providing a period when a non-selection voltage is impressed and a period when no voltage is impressed to the other region during selective scanning period of one region and using the signal voltage to be impressed in the period when the non-selection voltage is impressed as a prescribed gradation signal. CONSTITUTION:Figures a-c respectively indicate the waveforms of the impressed voltages on a scanning voltage, signal voltage and liquid crystal layer on the upper side; figures d-f similarly indicate the waveforms of the respective impressed voltages on the lower side; Vs indicates a selection voltage, and Vn indicates the non-selection voltage. Ta is one scanning period, Ts is the period for impression of the selection signal, and Tf is the period of one frame. The polarity of the impressed voltage is inverted in the ensuing frames in order to convert the voltage to be impressed to the liquid crystal layer to AC. The period Tb when the non-selection voltage is impressed and the period Tn when no voltage is impressed exist in the lower region in T1 during scanning of the upper region. Conversely, the period Tb when the no-selection voltage is impressed and the period Tn when no voltage is impressed exist in the upper region in T2 during scanning of the lower region. The prescribed gradation signal is impressed to the signal electrodes in the period Ts. The difference in the display luminance in the respective upper and lower regions is thereby decreased.

IPC: E02B3/06
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent an increase of weight and a scour of a tip end of a base board as much as possible when the width of the base board is enlarged more than the height of a caisson. SOLUTION: A bank body 13 is at its intermediate part formed in a slope or a curved surface, and is at its lower part formed in a divergent shape of gentle curvature. A retroflexed part 12a is provided on upper surfaces of both end parts of the base board 12 connected with a caisson. Both end surfaces of the base board 12 are formed in divergent inclined planes 12b. A part from the intermediate part to a crest 17 of the bank body 13 is formed in a convergent shape. Thereby, a scour is prevented when the wave is passed even if it is an ultra broad footing caisson that enlarges the width of the base more than the height of the caisson. Furthermore, force of the wave that acts on the crest can be weakened, and overturning moment applied to a bottom of the base board can be reduced.

Abstract: PURPOSE:To hold the height of free surface of molten metal constant by detecting resonance frequency in an LC circuit supplying high frequency current to a coil and adjusting the supplying velocity of the molten metal or supplying velocity of a solid metal. CONSTITUTION:The molten metal is supplied into a mold 8 through a header 6 in a tundish 5 and electric conducting coil 7. At the time of supplying the high frequency current to the electric conducting coil 7, a pinch force is generated between the coil 7 and the molten metal 1 to form space P, where the molten metal does not exist in the range of front face of the coil 7. The high frequency current is conducted to the coil through the LC parallel resonance circuit and the resonance frequency (fo) at this time is varied according to size of the space P, and the space P is varied according to height of the molten metal 1 surface. The resonance frequency (fo) is detected, and by adjusting a sliding gate 3 in a ladle 2, the height of molten metal 1 surface in the tundish 5 can be held to the constant.
