Title: Method and device for observing electrostatically charged corpuscular ray
Inventor: TSUJI YASUSHI
IPC: G01T1/29
Filed: 1985-06-20
Abstract: PURPOSE:To make the intensity of a primary electron beam extremely weak and to prevent a diffraction image from being distorted by deflecting electrostatically charged corpuscular rays so that a sample and a plane observation member are in specific position relation. CONSTITUTION:When the angle distribution of charged corpuscular rays 12 emitted by the sample 11 are observed by the observing member (e.g. channel type secondary electron multiplier plate) 16 arranged in a plane, the charged corpuscular rays 12 are deflected by a grid member 17, etc., between the sample 11 and observation member 16. The degree of the deflection is so set that S= aRsintheta (theta: constant), where R is the length of the perpendicular 18 from the sample 11, S is the distance from it to a point 15 of incidence, and theta is the angle of the corpuscular rays from the sample 11 in the traveling direction. Consequently, even if the primary electron beam incident on the sample 11 is made extremely weak, the diffraction image is never disable to be observed.

Abstract: PURPOSE:To surely extract synchronism without lowering receive margin by performing sampling for several times at uniform interval during a period of at least 1/2 that of a start bit elapse after the first level of a reception signal is changed, and assuming a bit as the start bit when the same levels are obtained in all the sampling. CONSTITUTION:When a start signal 10 of level (0) is supplied to a serial data input terminal 40, the signal of level (0) is fetched in a reception part 20 sequentially at time t1-t8, and is shifted by a shift register. When the sampling of level (0) is performed eight times the output Q9 of a flip-flop 29 goes to the level (0) at the leading edge time t9 of the next short cycle clock signal, and a signal of level (1) is outputted from a NOR circuit 31. Therefore, an RS flip-flop 33 is set, and a clock signal switching circuit 35 outputs an ordinary cycle clock signal after a time t9.

And the output of comparison is amplified through the amplifier 2, and the output signal passed through the LPF3 is turned into the DC voltage signal to drive the oscillator 4. At the same time, a phase comparison is given between the signal obtained by giving a phase shift to the output of the oscillator 4 through the pi/2-phase shifter 6 via the synchronous phase comparator 5. And this output of comparison is supplied to the detection circuit 7 consisting of the LPF and the Schmitt circuit to decide the synchronous state of the PLL loop. This decision signal is used for the gain control of the amplifier 2. Thus the effect of the input noise  is avoided without varying the DC voltage level which drives the oscillator 4. And  the response property can be increased.

Filed: 1990-05-24
Abstract: PURPOSE:To improve the joint strength of a package by attracting a cover superposed on a flange to a metallic auxiliary plate and pressing the cover to the flange via the metallic auxiliary plate which does not deflect when pressed to the flange. CONSTITUTION:The cover 2 attracted onto the metallic auxiliary plate 6 by the effect of a permanent magnet 7 is superposed on the flange 13 and the front end of a tightening mechanism 4 is pressed atop the metallic auxiliary plate 6. The cover 2 is pressed to the flange 13 via the plate 6 by turning a thumb nut 32 fitted with a stud bolt 31, by which the clearance interposed between the cover 2 and the flange 13 is removed. The warping of the cover consisting f an extremely thin metallic sheet and the floating of the periphery from the flange do not arise even if the cover is pressed to the flange by the force stronger than the force of the conventional welding jigs via the metallic auxiliary plate. Since the cover comes into tight contact with the metallic auxiliary plate, an overall heat capacity increases and a temp. difference does not arise between the cover and a container at the time of heating and cooling. Namely, the welding strength of the package improves.
