Title: Swivel tank setting structure in fuel tank for vehicle
Inventor: MOMOO SATOSHI
IPC: B60K15/03
Filed: 1985-08-02
Abstract: PURPOSE:To improve durability in a fuel tank, by supporting a swivel tank on a side wall of a fuel tank excellent in rigidity in a vertical direction via a bracket. CONSTITUTION:A bottom wall 4a of a swivel tank 4 is opposed to bottom wall 2a of a lower shell 2 with some space, and a side wall 4b is supported on side walls 2b and 2b of the lower shell 2 via brackets 5 and 5. In this consti tution, even if vertical vibrations are inputted into a fuel tank 1, each of bottom walls 4a and 2a of the swivel tank 4 and the lower shell 2 is at a distance so that deflection of the bottom wall 2a of the lower shell is not checked at all, thus local stress concentration is avoidable. And, since the side wall 2b is large in rigidity, it surely supports the swivel tank 4 while there is no occur rence of the stress concentration due to deflection. Thus durability in the fuel tank is improvable.

Abstract: PURPOSE:To heat the whole of a sample uniformly irrespective of movement of the sample and thereby to keep a melted state invariable and to enable accurate execution of measurement of the qualtity of an interposition and identification thereof by making an electron beam scan two-dimensionally in a prescribed sphere. CONSTITUTION:A toroidal deflecting coil 10 is provided just in front of an electron gun 8, an electron beam E, irradiating a sample 6 is made to scan two-dimensionally over a prescribed sphere by the coil 10, as indicated by an alternate long and short dash line, and thereby the sample is heated to be melted. On the occasion, the radius of the electron beam irradiating the sample 6 is made equal to the size of the sample 6. By making the electron beam scan two-dimensionally in this way, the whole of the sample can be irradiated by the electron beam even when the sample 6 moves in a melting chamber 5, and therefore the sample 6 can be melted evenly without nonuniformity. As for a scanning area of the electron beam, an optimum melted state can be obtained when the area is made twice as large as the surface area of the sample 6 at the time when the sample is viewed from the direction of irradiation of the electron beam. According to this constitution, measurement of the quantity of an inclusion and identification thereof can be executed accurately.

Abstract: PROBLEM TO BE SOLVED: To have merit in the aspect of cost in use of a power supply cable and facilitate the security of insulation distance between a discharge electrode and the constituent parts of a laser oscillator, by connecting earth resistors severally to the anode and the cathode of a DC high-voltage power source. SOLUTION: For a gas laser oscillator, earth resistors 12a and 12b are connected severally to the anode and the cathode of a DC high-voltage power source 2. Then, the high voltage of a discharge electrode is decided by the output voltage and the partial voltage ratio between these resistors 12a and 12b, and the output voltage of the DC high-voltage power source 2 itself is the same, but the voltage to ground of the discharge electrode can be suppressed lower than that in the case of conventional constitution. Hereby, the one where the withstand voltage of the power supply cable is lower than that of conventional one can be used, and also the insulation distance between the discharge electrode and the constituent parts of the gas laser oscillator can be made small.
