Filed: 1989-08-12
Abstract: PURPOSE:To perform high-speed driving of a relay by allowing a bias current under a working current of the relay through the relay excitation coil to constantly flow through a constantly closed contact and resistance for a bipass. CONSTITUTION:The first DC voltage V1 is impressed through a constantly closed contact Nc and the second DC voltage V3 is impressed through a constantly opened contact NO on a series circuit of a switching element Q, in which an excitation coil L of a relay Ry and resistance R3 for a bypass are in series connected. A capacitor C2 for the bypass is in series connected to the constantly closed contact Nc, while the first DC voltage V1 is set up at higher voltage than rated voltage of the relay and the second DC voltage V3 is set up at rated voltage, further resistance value of the resistance R3 for the bypass is set up so that a current flowing through the excitation coil L may be less than a relay working current. Accordingly, when the switching element Q turns ON, immediately a current more than the relay working current flows. Thereby, high-speed driving of the relay Ry can be performed.

Title: Excimer laser oscillation device and its drive
Inventor: OMI TADAHIRO
IPC: H01S3/225
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To take place repeatedly a laser oscillation for a long period of time and to make it possible to obtain a desired laser output, by a method in which a voltage is applied to one pair of electrodes so that the direction of a current, which is made to flow between the one pair of the electrodes, is changed at a prescribed period. SOLUTION: A charge is stored in a capacitor 3 for charge storage use using a high-voltage power supply 1 and a charge is stored in a capacitor C1 for charge storage use using a high-voltage power supply 15. When a trigger is put in a thyristor 5 to turn the thyristor on, the charge stored in the capacitor 3 is discharged. A pulsed voltage is applied to both ends of a capacitor 8. A voltage of a shortened pulse width appears in both ends of a capacitor Cp by a magnetic switch 7. When the voltage, which is applied to both ends of the capacitor Cp, is changed, a preionizer 11 starts discharge and free electrons are produced in a laser chamber. Even discharge is generated between discharge electrodes 10a and 10b, and a laser is oscillated.  Thereby, the life of the laser chamber can be prolonged and a desired laser output can be obtained for a long time by a control only of an applying voltage to one pair of the electrodes 10a and 10b.

Title: Fuel injection nozzle
Inventor: IIYAMA AKIHIRO
IPC: F02M61/18
Filed: 1990-08-08
Abstract: PURPOSE:To prevent a trouble, wherein a utilization factor of air is decreased by overlapping atomization to generate a smoke, by forming an opening part, facing to the inside of a nozzle body partly in a jet hole, into a chamfering shape. CONSTITUTION:When fuel is press-fed to a nozzle body 1, first a needle valve 2 causes the initial lift to inject fuel from jet holes 3, 4. Here, an opening part 4A, facing to the inside of the nozzle body 1 of the jet hole 4, is formed in a chamfering shape, so that inflow fuel from an annular clearance between the nozzle body 1 and the needle valve 2 is allowed to smoothly flow in the jet hole 4 with no interference with each other and jetted into a combustion chamber at a small injection angle, as shown in the drawing, to extend atomization to a position far distant from the jet hole 4. On the other hand, inflow fuel in the jet hole 3, whose opening part 3A is formed in a sharp shape without chamfering, interferes with each other to generate a turbulent flow, and the fuel is jetted at a large injection angle in the vicinity of the jet hole 3. Since the jet holes 3, 4 are alternately arranged, an environment, where a smoke is not easily generated, is provided in the combustion chamber without overlapping the atomization with each other.
