Title: Double balloon catheter
Inventor: YOSHINO MASAO
IPC: A61M25/00
Filed: 1988-10-14
Abstract: PURPOSE:To prevent the contact of the leading end of a hard shaft with the wall of the bladder to prevent the damage of the wall of the bladder by forming a bladder wall damage preventing balloon to the leading end of the shaft other than a shaft pull-off preventing balloon so as to surround the shaft. CONSTITUTION:A shaft 1 is inserted in the urethra 9 before balloons 3, 4 are inflated. In such a state that the balloons 3, 4 are not inflated, not only the balloon parts but also other parts are not almost different from a catheter in a thickness and there is no trouble in the insertion of the shaft in the urethra 9. By inflating the pull-off preventing balloon 3, the catheter is hooked with the inlet 82 of the bladder 8 to be prevented from pulling-off. When the bladder wall damage preventing balloon 4 at the foremost end of the shaft 1 is inflated, the leading end of the shaft 1 is hidden by the balloon 4. By this method, the leading end of the shaft 1 harder than the balloon 4 is not brought into contact with the bladder wall 81 at the time of use and the bladder wall 81 is not damaged.

Title: Non-aqueous electrolyte secondary battery
Inventor: EDA NOBUO
IPC: H01M10/0567
Filed: 1987-10-15
Abstract: PURPOSE:To have a non-aqueous electrolyte secondary battery excellent in cycle life by adding triethyl phosphorate to noon-aqueous electrolyte in specified amount. CONSTITUTION:To electrolyte, phosphorate ester, in particular triethyl phosphorate, is added, which has intramolecular polarizativeness to permit orientation (adsorption) to metal lithium and does not have isolate electron couples in molecule. That is, 1-7vol.% triethyl phosphorate is added to a mixture solvent of propylene carbonate and dimethoxyethane. This hinders lithium neg. electrode from contacting electrolyte solvent as a base, so that wear of the neg. electrode is reduced to provide an improved battery life with charging/discharging.

Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for eliminating the conventional drawback of a chemical vapor deposition that a vaporized metal film is deposited on an insulating member in a processing chamber to degrade insulation to reduce instability of the plasma. SOLUTION: In a device for performing a chemical vapor deposition on a substrate 18 placed in a processing chamber by supplying a processing gas to the substrate 18 from a shower head electrode 20 and by generating a plasma trenches 74 having a large aspect ratio are made on the insulating surface 72 of the outside surface of an insulating member 70 supporting the shower head electrode 20.

Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To provide service on various sounds in a virtual space by outputting only sound information of the other user character existing in a designated range in a three-dimensional space. SOLUTION: Only sound information from the other user character existing in a sphere having a radius (r) with a self character in the three-dimensional space as a center is outputted to a self terminal. Namely, the range (r) where sound is to be outputted is designated by a range designation information input device and data which is multiscan-transmitted is received by a network reception device. Position data of the other user character is extracted from a multicast packet and a distance (d) is calculated based on position data. The distance is compared with the designated range (r), and whether sound is to be outputted or not is decided. When the sound is decided to be outputted, sound information of the other user character is extracted from the multicast packet. An adder executes the above processings and sound information is finally outputted from a sound output device.  Thus, flexible sound field control can be executed.
