Title: Method for analyzing noticed element in sample by electron ray irradiation
Inventor: TAJIMA HIROSHI
IPC: H01J37/252
Filed: 1985-08-30
Abstract: PURPOSE:To non-destructively analyze the concn. distribution of a noticed element in the depth direction in a short period by determining the concn. distribution of the noticed element at the specified depth in accordance with the differential signal between an X-ray detection signal when an electron ray is irradiated to the analytical point of a sample and an X-ray detection signal obtd. by changing the diameter of an electron beam. CONSTITUTION:The electron beam 2 emitted from an electron gun 1 is accelerated by the high voltage from a high-voltage power source 16 and is converted by a convergent lens 3 and an objective lens 4. The converged beam irradiates the sample 5, from which the characteristic X-ray 6 is generated. The X-ray 6 is detected by an X-ray detector 8 by increasing the acceleration voltage each slightly. The detection signal is fed to a measuring circuit 9 by which the X-ray intensity is counted. The beam diameter of the X-ray beam 2 decreases gradually in this stage and the region where the X-ray is generated increases in the depth direction. A control circuit 10 stores the count value in a storage circuit 11 and stores the difference in the count values before and after the increase of the acceleration voltage by one step into the storage circuit 11. The concn. distribution of the noticed element at the specific point in the depth direction of the element is calculated in an arithmetic circuit 12 in accordance with the stored value thereof and is displayed on a display device 13.

Abstract: PURPOSE:To accelerate the resistance increase of a buried layer thereby to obtain a high resistance buried type semiconductor laser having small efficiency of a threshold current by providing a bandlike structure having an active layer and a single hetero structure on an optical guide layer to be buried. CONSTITUTION:A bandlike structure having a single hetero junction structure made of an active layer 14 and a semiconductor layer 15 including a forbidden band width wider than the layer 14, and a double hetero junction formed on an optical guide layer 13 provided through a clad layer 12 on one main surface of a semiconductor substrate 1 with an Fe-doped buried layer 17 of a high resistance semiconductor including forbidden band width wider than the layer 14 provided on the side of the structure are formed.

Title: Driving stage device and actuator unit for same
Inventor: TOMITA YOSHIYUKI
IPC: B23Q1/48
Filed: 1989-07-25
Abstract: PURPOSE:To improve responsiveness by driving a stage surface directly by actuator units (driving device) for one direction and one actuator unit (driving device) for an orthogonal direction. CONSTITUTION:The XYtheta driving stage device can drives the stage surface in an X and a Y direction and a rotational thetaZ direction in the XY plane. For example, when Z-directional actuator units 10e - 10g are disregarded, a body 3 to be driven is to move approximately in a +X direction by the +X- directional driving of and X-directional actuator unit 10a. At this time, the driven body 3 is low in X-directional rigidity to elastic link parts 9b and 9c of Y-directional actuator units 10b and 10c, so the driven body easily deforms elastically when receiving an X-directional force. Therefore, the driven body 3 is driven in the X direction by the X-directional actuator unit 10a.

Abstract: PROBLEM TO BE SOLVED: To solve irregularity in printing or the like caused by clogging of ink at an end part of a carved face of a plate cylinder in back coat printing with a gravure printing machine on a base film of video-printer ribbon. SOLUTION: A carved width D2 of a plate cylinder 23 is made wider than a printing width D1 , and the printing width D1 is equalized to a width D4 of an impression cylinder. Since an end part 23b of a carved face 23a likely to be clogged by stay of ink comes not to be used by setting (the graved width D2 ) > (the printing width D1 ), irregularity in printing caused by clogging of ink at the end part 23b is inhibited. Under printing width D1 =740mm, graved width of plate cylinder D2 =780mm, base film width = 760mm, and impression cylinder width D4 =740mm, irregularity in printing is not generated until a base film length reaches at least 2000km.
