Abstract: PROBLEM TO BE SOLVED: To provide a stable vacuum valve that is excellent in contact resistance and cut-off characteristics. SOLUTION: The contact material of a vacuum valve comprises a high conductivity constituent cupper or the like and an arc resistant constituent consisting of Cr, in which particles having a diameter in the range of 1-150 μm occupy at least 90 vol.%, and the ratio of the difference between the thermal expansion coefficient α900 at 900 deg.C, and the thermal expansion coefficient α50 at 50 deg.C, to the thermal expansion coefficient α900 at 900 deg.C of the contact material, [(α900 -α50 )×100/(α900 )] should be not less than 0.8% and not more than 12%. Thereby, the formation of a groove produced in the interface between a Cr particle and a Cu matrix after undergoing a brazing process is suppressed so that the stabilization of the static withstand voltage, contact resistance and cutoff characteristics can be realized.

IPC: G11B5/84
Filed: 1987-09-18
Abstract: PURPOSE: To lessen the width of the tapered surface at the edge of a magnetic tape which was cut and establish a fine workmanship of the cut face of the edge by forming a gap with the side circumferential surface of a columnar cutting blade made in a small diameter for occluding a circular disc blade with the columnar blade and making the width of the produced gap 1.5-5 times as large as the thickness of the circular disc blade. CONSTITUTION: A gap 10 is formed while the side circumferential surface of a columnar cutting blade 8 is made a small diameter 9 for occluding a circular disc blade 5 with the columnar blade 8, and the width L of the formed gap 10 is made 1.5-5 times as large as the thickness of the circular disc blade 5. As a result, a web 11 of magnetic tape transported is cut in this gap 10 having a very small width, so that it is possible that the tape web 11 is prevented from being drawn into the gap 10 together with the circular disc blade 5 and cut by the occluding part of the two blades 5 and 8 in a good performance.  Accordingly the tape web 11 can be cut in a width approximately equal to the length of the columnar blade 8 in good workmanship, and a high quality magnetic tape with excellent electromagnetic conversion characteristic can be yielded in which a fine workmanship of the cut face of the edge is ensured.

Title: Controller of bath
Inventor: TSUBOI MAKOTO
IPC: F23N5/20
Filed: 1983-12-15
Abstract: PURPOSE:To prevent heating of an empty bath boiler due to misoperation of an operation switch, by a method wherein when disorder such as momentary power failure has occurred on a supply power source, restarting or suspension of combustion operation after restoration of the power source is determined based on a matter whether the combustion operation has been performed prior to the disorder of the power. CONSTITUTION:When momentary power failure is generated, an output of a control part 9 including a close state of a fuel controller 2 is turned OFF wholly once. When a power source 10 is restored at a time T4, an operation switch 6 is kept at an ON state as it was and an output of a charge and discharge timer 11 is kept at an ON state as it was also. Judgement of momentary suspension of power is performed by a judging part 12 in a predetermined period (corresponding to the period from a time T0 to a time T1) from the time T4 to a time T5. An output of the judging part 12 is turned into an ON signal upon completion of a timer period of the charge and discharge timer 11. Combustion operation is restarted through the ON output of the decision part 12. The titled controller possesses such function that when it was found that a condition wherein the power source was applied to a control circuit was temporary suspension of the power source during combustion operation, the combustion operation is restarted, but otherwise the same operation is not made to perform.

Title: Magnetic tape cartridge
Inventor: TSUYUKI SEIJI
IPC: G11B23/107
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To exactly execute releasing operation and to lessen friction and wear by executing reel rotation blocking by a blocking member which moves attachably and detachable to and from the reel and restrains the reel rotation, an energizing member for this blocking member and a releasing member which moves the blocking member 9 in a releasing direction by moving according to chucking operation. SOLUTION: A revolving shaft 12 approaches the base surface of the reel 2 and a drive gear is meshed with a reel gear 24 by the chucking operation. When the reel 2 is slightly moved upward and held, the tips of the drive gear come into contact with the front ends of the leg parts 63 of the releasing member 6 and push up the releasing member. Accompanying the same, the releasing member 6 moves upward by overcoming the energizing force of the energizing member and the blocking member 4 also moves in the upward releasing direction together with the releasing member 6, thereby releasing the engagement of a blocking gear 42 and detaining projection members 27. A main body part 61 is molded of a high-rigidity resin, by which deflection deformation is lessened and the uneven contact of the leg parts 63 with the insertion holes 26 is eliminated and the engagement is surely released.  The releasing member 6 rotates and slides relative to the blocking member 4 via a sliding contact part 62 having a low friction characteristic.

IPC: A61M25/10
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To improve the effectiveness of a balloon to a constricted region and to shorten the time required over the entire part of a treatment by using an expansion balloon mounted at the outside surface of a catheter and an expandable centering balloon. SOLUTION: Expansion and contraction of the expansion balloon 14 are repeated from one time to several times in order to reduce the size of the constriction of the expansion balloon. At the point of this time, the centering balloon 41 is inflated. The centering balloon 41 is symmetrically inflated and is small in width and long-sized, by which the centering balloon 41 is made to function so as to execute only the centering of a tubular cavity 13 for treatment of a catheter 12 within the region subjected to the constriction till just before. The vital perfusion of the max. possible extent is thus made possible. A radiation irradiation source 28 is advanced through the tubular cavity 13 for treatment of the catheter 12 to the original constriction site.  Since the centering balloon 41 is inflated, the catheter 12 and a radiation irradiation source 28 are exactly centered within a vital conduit and the passage.
