Title: Flushing device of field radiation type electron gun
Inventor: OBARA KENJI
IPC: H01J37/06
Filed: 1988-12-09
Abstract: PURPOSE:To reduce aberration by reducing a supply quantity of a heating current per one time to more extent as FL times is smaller, on the basis of a signal indicating flushing(FL) times form a counting means for easing up an increase in leader voltage due to an increase in FL times. CONSTITUTION:When acceleration voltage and leader voltage are impressed on an emitter 1 to continue field radiation of an electron beam, unevenness is generated in the tip periphery due to the impact of positive ions to destroy an emission pattern. Then, when an FL switch 13 turns ON, a signal for indicating a first time of FL is sent form a counting circuit 12 to a timer 11. The timer 11 controls an ON/OFF circuit 10 based on the information of a memorized heating current supply time to supply the heating current to a filament 2 for a prescribed time. Similarly, 2 to (n) times FL are performed, a supply time is slightly lengthened in company with times of FL. When the pulse width reaches the upper limit value, it is fixed.

Title: Method for improving creep characteristic of titanium alloy and titanium alloy
Inventor: KELLY CARL E
IPC: C22F1/18
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To improve the creep characteristics of a titanium alloy by subjecting a titanium forged body to solution treatment at a temp. higher than β transus in succession, executing cooling under specified conditions, subjecting it to solid solution at a temp. lower than β transus, again executing cooling and subjecting it to precipitating treatment under specified conditions. SOLUTION: At first, an α+β or near-α alloy material is forged into a prescribed shape. This forged body is subjected to solution treatment at β transus or above. Preferably, it is regulated to the temp. higher than β transus by 25 to 100 deg. F. Next, it is cooled to a temp. lower than the martensite forming temp. Mf . The cooling rate is preferably regulated to about 150 450 deg. F/min. After that, sub β solution treatment is executed at a temp. lower by about 100 deg.F from β transus. Then, the forged body is cooled to <=Mf at a rate so as to form the acicular α phase. Finally, precipitation stabilizing treatment is executed. This treatment is executed at 800 to 1300 deg. F for 2 to 8 hr and optimizes the characteristics of the material.

Title: Optical scanner
Inventor: KIKUCHI KAZUO
IPC: H04N1/36
Filed: 1988-12-13
Abstract: PURPOSE:To improve the accuracy in detecting the position of a light beam with simple constitution by imaging the incident light beam just before a photodetecting surface in the direction perpendicular to a deflecting direction so that the light beam is diffused as a longitudinally long light spot on the photodetecting surface. CONSTITUTION:An imaging optical means 330 and a unidirectional convergent optical means image the incident light beam on the photodetecting surface of a light beam detecting means 340 just before the photodetecting surface in the direction perpendicular to the deflecting direction and, therefore, the light beam is diffused as the longitudinally long light spot on the photodetecting surface. The permissible values for the deviation in the scanning locus of the light beam by the production errors, etc., of the deflecting means 320 and the deviation in the optical axis by a fine adjustment error and the distortion of a supporting structure are, therefore, increased. Since both the optical means act in the direction to decrease the deviation in the scanning locus of the light beam by the deflecting means 320 and the deviation in the optical axis by the distortion of the supporting structure, the permissible values of the deviations increase. The degradation in the accuracy of detecting the position of the light beam is prevented by the simple constitution in this way.

Abstract: PURPOSE:To always keep printing speed high while avoiding the joint of a photosensitive body and forming an image by using a mark position where an intermediate transfer body is selected, as an image forming reference position, and determining image forming timing based on the reference position and a time difference. CONSTITUTION:One photosensitive body position detecting mark is provided on the photosensitive body, and plural intermediate transfer body position detecting marks 2 are provided on the intermediate transfer body 1.
