Title: Control method for engine generator
Inventor: SANGO MASAYUKI
IPC: F02D1/02
Filed: 1984-02-01
Abstract: PURPOSE:To safely start as far as load close to a generator by increasing fuel supplied to an engine simultaneously with load making or after making and setting output voltage at a value lower than the rating and suitable for load characteristic and further releasing all operational control when an engine speed reaches the rated value. CONSTITUTION:After making load, an engine raising command circuit 7 is actuated by means of a load making detection circuit 11, and the governor lever 9 of the engine is drawn by means of a solenoid 8 to increase a fuel supply and rotation of the engine is quickly restored. Since there is no rise in frequency of a generator output due to load making, there is neither increase in restored voltage of a control relay used in each circuit nor a wrong action. Further, a generator output voltage is previously increased at the time of load making, and said voltage is controlled at a value adjusted to load characteristic in consideration of a condition of restoration of engine speed by means of a voltage setting circuit 10 at load starting time. Thus, even under load of a big rush current the engine can be started as far as the load about same as the rated capacity without trouble.

Filed: 1989-01-27
Abstract: PURPOSE:To maintain and ensure the same shape arbitrariness and thermal stability as a resin magnet and realize a rare earth-iron permanent magnet having performance superior to the metallic stability of a hot press magnet by making a rare earth-iron thin piece having a specific alloy composition by ultra-quenching be an aggregate of an arbitrary shape and by fixing the thin films. CONSTITUTION:Rare earth-iron thin films having a specific alloy composition by ultra-quenching are made an aggregate of an arbitrary shape, and the thin films are fixed at a sec level at a low pressure. Therefore, since not only a rare earth-iron permanent magnet of an arbitrary shape can be obtained very speedily, but the production or/and growth of phase B of R2Fe(Co)14 is suppressed, the thermal stability of a permanent magnet is not degraded due to a considerable decrease in the specific coercive force Hcj of the original thin piece or in its temperature coefficient. As a result, a rare earth-iron permanent magnet having a residue magnetic flux density Br9KG or more and two families of specific coercive force Hcj 8kOe and 15kOe or more can be obtained while high shape arbitrariness and productivity are ensured.

Filed: 1979-02-20
Abstract: PURPOSE:To avoid internal shortcircuiting caused by the fact that the metallic mercury produced due to discharge reaction moves to the cathode side by containing mercury chloride in a positive electrode which uses mercuric oxide as an active material. CONSTITUTION:One or more mercury chlorides of HgCl2, Hg2Cl2, Hg2OCl, and Hg4Cl2 are contained in the positive electrode 1 which uses mercuric oxide as an active material. It is desirable that the content is 0.001-0.005wt% of the positive flux. For example, 3wt% of graphite powder and 0.001-5.0wt% of mercurous chloride (Hg2Cl2) are mixed in red mercuric oxide and are compressed and molded, which results in the positive pellet 1. This prevents the metallic mercury produced due to discharge reaction from being aggregated and from being shortcircuited with the negative electrode.
