IPC: H01J9/02
Filed: 1990-06-26
Abstract: PURPOSE:To have stable emission of current of approx. 50muA under 1X10Torr by subjecting an emitter of Nb carbide mono-crystals to a specific treatment. CONSTITUTION:In ethylene or other hydrocarbon gas (at 1X10<6>Torr), an emitter of Nb carbide mono-crystals are heated to 1400-1800'C for 5000 sec or longer. i.e., over 5000 L, where one L is equivalent to 1X10<-6>Torr.sec. Thereby a graphite film is formed on the surface. This is followed by evacuation to an extra-high vacuum (for ex., 1x10<-10> Torr), and a strong electric field over 10<3>V/cm is impressed. This causes change of the emission pattern, and gives stabilization of the emission current. Thereby stable operation is obtained such that short duration noise is below + or -0.2% and the drift is below + or -0.1%/hr even under the condition with a degree of vacuum of 1X10<-10>Torr and an emission current of 50muA.

Title: Control method for friction separated paper feed
Inventor: ISHII YASUAKI
IPC: B65H7/18
Filed: 1984-08-14
Abstract: PURPOSE:To eliminate a defect of overlapping of two paper sheets fed one after the other by stopping temporarily, at a preliminary feed position, a paper sheet fed from a paper feeding part and then adjusting the predetermined re-feeding time depending upon actual conveyance velocity at the time of re-feeding. CONSTITUTION:When a paper feeding signal is given, a feed roller 2 and a pickup roller 1 are made to rotate and the uppermost paper sheet in a paper sheet stack is fed forward. The feeding of a paper sheet is stopped, when its leading edge is detected by a sensor 1, and preliminary paper feeding is finished. The feeding process starts again on the predetermined re-feeding time and a grip roller 3 is driven to convey a paper sheet. As soon as the paper sheet reaches a sensor S2, an operation control means 8 calculates linear conveyance speed V1. The detection of the trailing edge of the paper sheet by the sensor 1 causes another paper sheet to be fed preliminarily and it follows that the re-feeding time of the spare paper sheet is corrected by the aforesaid linear conveyance V1.
