    • It is an object of this invention to provide an electron generating apparatus which is hardly influenced by variations in driving voltage, an image forming apparatus using the electron generating apparatus, and a method of manufacturing and adjusting the same. The row wiring layers of a multi-electron-beam source (300) are sequentially selectively switched by a control circuit (302) and applied with a pulse voltage having a value about 1.05 to 1.5 times the maximum value of a normal driving voltage from a DC voltage source (301). The characteristics of all surface conduction electron-emitting devices of the multi-electron-beam source (300) are shifted to the high potential side. With this process, even when the driving voltage becomes high due to superposition of noise and the driving voltage, variations in electron-emitting characteristics caused by the voltage shift characteristics of the surface conduction electron-emitting devices can be prevented.
    • 本发明的目的是提供几乎不受驱动电压变化影响的电子发生装置,使用该电子发生装置的图像形成装置及其制造和调整方法。 多电子束源(300)的行布线层由控制电路(302)依次选择性地切换,并施加从正常驱动电压的最大值的大约1.05到1.5倍的脉冲电压 直流电压源(301)。 多电子束源(300)的所有表面传导电子发射器件的特性被转移到高电位侧。 通过该处理,即使由于噪声叠加和驱动电压而使驱动电压变高,也能够防止由表面传导电子发射器件的电压偏移特性引起的电子发射特性的变化。

    • Provided is a device for performing speed change not leading to engine stall in a working vehicle such as a wheel loader while sustaining a required tractive force and reducing fuel consumption. When a speed (“forward”, “second speed”) suitable for a work is selected by a speed change operator, control means makes a modulation clutch engaged in response to the vehicle speed drop and makes a lock-up state where a lock-up clutch is engaged transit to a lock-up and modulation clutch slip state where the lock-up clutch is engaged while the modulation clutch slips. Subsequently, the control means performs a clutch control for causing a transition to both clutch slip state where the lock-up clutch and the modulation clutch slip in response to the vehicle speed drop, thence causing the transition to a torque converter operation state where the modulation clutch is engaged and the lock-up clutch is released.
