Title: Method of generating low temperature of high density electron beam and its system
Inventor: HIRAOKA HIDEO
IPC: H01J37/28
Filed: 1981-07-27
Abstract: PURPOSE:To stably generate a desired high brightness electron beam for many hours by using a single crystal LaB6 whose axial direction is '100' as a cathode, heating the cathode at low temperatures, and setting and using the bias voltage in which beam current is located at the beam position. CONSTITUTION:A cathode 1 is composed of a single crystal LaB6 that has the '100' direction to the beam generation axis. As an example, the shape of its tip is the angle of a cone of 90 deg. and the radius of curvature on the top is 15mum. This cathode permits its temperature to be controlled variably by a heating power control circuit 11 which controls a heating power supply 9 and an  Wehnelt cylinder 12 can control the bias voltage applied to the Wehnelt cylinder by a bias voltage control circuit 13. Besides, an alignment coil 14 is controlled variably by a beam alignment control circuit 15 to align the beams. The said control systems are set to their specified values in accordance with the operation mode indicated by the central control unit 18 corresponding to an emission current measuring system 16 and a beam current measuring system 17.

Title: Ic-converted stable resistance circuit
Inventor: YAMASHITA NORIYUKI
IPC: H03H11/46
Filed: 1984-06-08
Abstract: PURPOSE:To obtain a resistance which is not influenced by a variation portion of an IC internal resistance by connecting a buffer amplifier between an input and an output, in a circuit constituted so as to obtain a current being proportional to a potential difference between two points. CONSTITUTION:A voltage of a point P1 and a voltage of a point P2 are inputted to an operation amplifier 50 in which an input impedance, an output impdedance, and a gain are 2(R+re),<infinity>, and (gm), respectively, so that an output can be obtained from point P3, P4. According to this circuit constitution, the circuit whose gain (gm) is not influenced by a dispersion of an internal resistance of an Ic is obtained. However, when it remains as it is, it does not become a resistance, therefore, ideal buffers 51, 52 are connected between the input and output points P1, P3, and between P2, P4, respectively. As a result, a current (i)=gmX(potential difference between P1, P2) being proportional to the potential difference between the points P1, P2 flows in from the point P3, and flows out of the point P4. In this way, even if a dispersion is generated in the intenal resistance of the IC, a stable IC-converted resistance can be obtained.

Title: Exposure controller for lens shutter camera
Inventor: KANEKO YOSHIYUKI
IPC: G03B7/097
Filed: 1989-05-11
Abstract: PURPOSE:To decrease the memory capacity of data and to facilitate data alterna tion by composing the table of a shutter second corresponding to a photometric value of shutter second difference data and setting the number of calculating times according to the photometric value. CONSTITUTION:The shutter second that ensures proper exposure with respect to each photometric value stepped in a prescribed manner is previously stored as the shutter second difference data in the table. The shutter second difference data in the table is read out and calculated in order, and is outputted as the shutter second at that time. The number of calculating times is set according to the potometric value. In other words, the table of the shutter second with respect to exposing quantity is stored in a ROM as the value of the difference in the shutter second. Thus, since shutter second data is finely set with a small ROM capacity and stored as table data, the second alteration is simplified.
