Abstract: PURPOSE:To improve turning-OFF characteristics without considering the balance with other characteristics so much by providing difference between the lifetime of carriers in a current path between main electrode parts and the lifetime of carriers in the other regions. CONSTITUTION:Difference between the lifetime of carriers in a current path between an anode part 2 and a cathode part 3 which are main electrode parts and the lifetime of carriers in the other regions are provided. Radiation 10 is selectively applied to excite crystal defects 7. Then, although a main current 6 is cut off at the time of turning-OFF, the lifetime of carriers remaining in a substrate 1 is reduced because of the existence of the defects 7 and hence the turning-OFF time is reduced. At the time of turning-ON and in the ON state, as no defect 7 exists in the main current path, the current flows smoothly without an obstruction and the turning-ON time can be reduced and a forward voltage is kept low. With this constitution, the turning-OFF characteristics can be improved.

IPC: H01J61/92
Filed: 1981-12-22
Abstract: PURPOSE:To obtain a new fluorescent light-source tube, in which any grid is not needed, by providing lead-out electrodes and focusing electrodes in the fluorescent light-source tube, in which a phosphor provided on an anode emits light by a cathode luminescence. CONSTITUTION:When lead-out electrodes 9a and 9b are biased positively to a cathode 6, and an arbitrary anode and external lead 2 which is led outside a vacuum case is biased positively to the cathode 6, thermions 11 flow out of the heated cathode 6. After that, when focusing electrodes 10a and 10b are biased negatively to the cathode 6, the thermions 11 led out of the cathode 6 are attracted toward the anode 2, the density of current flowing into a phosphor 3 increases, and the efficiency of the current increases.

Title: Ink jet recorder
Inventor: KUAMI MICHITOKU
IPC: B41J2/16
Filed: 1981-12-22
Abstract: PURPOSE:To maintain the ink particle speed constant independently of the ink temperature thereby to obtain an excellent printing quality, by providing a heat- softening material at the junction between an ink pressure chamber and a piezoelectric element. CONSTITUTION:Since the strain efficiency of a heat-softening material 9 at the junction between a piezoelectric element 6 and a vibrating member 7 lowers with the increase of temperature, the lowering of the strain efficiency cancels out the increase of the ink particle speed due to the ink viscosity; therefore, the particle speed hardly changes with a temperature change. In addition, since a driver circuit 8 is only required to deliver a constant output, the control can be facilitated.

Abstract: PURPOSE:To reduce the pressure of a pump chamber, delay the spark angle, and improve the engine performance in the intermediate load area by increasing the communicating area between a through hole and a relief hole in the intermediate load area when a governor sleeve is retreated as the engine load is increased. CONSTITUTION:In the low load area, only a through hole 41 on the rear end side is communicated to a relief hole 37, and the spark advance quantity is determined by the flow quantity of fuel restricted by the through hole 41. When a governor sleeve 28 is retreated as the load is increased, a through hole 41 on the tip side is communicated to the relief hole 37, the communicating area is gradually increased, and the spark advance quantity is decreased. When the communicating area becomes the maximum, the maximum spark lag state is obtained. When the load is further increased, the through hole 41 on the tip side maintains the communicated state to the relief hole 37, however the communicating area between the through hole 41 on the rear end side and the relief hole 37 is decreased as the governor sleeve 28 is retreated, and the spark advance quantity is increased. In the high load area, only the through hole 41 on the tip side is communicated to the relief hole 37, and the maximum spark lag state is obtained.
