Title: Operation point controller of optical modulator
Inventor: KOIZUMI TOSHIO
IPC: G11B7/125
Filed: 1982-09-30
Abstract: PURPOSE:To record correctly bits corresponding to the run length of a modulating voltage on a recording surface by detecting and superposing the low-frequency DC component of the modulating voltage upon the operation-point determination voltage of an optical modulator, and controlling an operation point. CONSTITUTION:The modulating voltage 9 is applied to the optical modulator 2 through an n-stage shift register 18 and also applied to an n-stage digital correlator 19 at the same time. The correlator 19 detects only the number of high or low levels of the voltage 9, clock by clock, successively and a subtracter 20 subtracts n/2 from said number and applies the result to a D/A converter 21; and the converter outputs the means DC component of the voltage 9 as an analog signal, which is smoothed by a low-pass filter 16' and used as the operation varying voltage 19 of the optical modulator 2. Therefore, a wide-band filter is used as the filter 16', so delay time is a little. This delay time is constant depending upon the clock and delay is canceled correctly by a register 18.

Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To display the effective range of a by-pass capacitor on a printed board in each power supply used for the printed board on a power supply area in each sort of the power supply. SOLUTION: In the case of plotting the effective range of a bypass capacitor for a selected power supply on a screen as an ellipse, a by-pass capacitor arrangement evaluation tool 12 finds out AND between the effective range and a power supply area and executes plotting processing so that the effective range is displayed only in the power supply area. Since the effective range of a part stuck out from the power supply area is not plotted, an ellipse is not displayed on two or more power supplies even when plural power supplies are simultaneously displayed, so that the effective ranges of by-pass capacitors for respective power supplies can be easily and precisely grasped.

IPC: H01L21/30
Filed: 1988-07-07
Abstract: PURPOSE:To easily judge a sectional shape of an electron beam for improving accuracy of astigmatic adjustment by radially forming a plurality of dotted patterns on a conductor substrate. CONSTITUTION:The subject sample is formed, for example, by radially arranging a plurality of dotted patterns made of gold on a conductor substrate 2 consisting of a silicon substrate. In this case, the respective diameters of a plurality of dotted patterns 1 and the distances between dotted patterns 1 have about the same size with a beam diameter of an electron beam, which is an object of adjustment. Accordingly, seeing a scanning electron microscope image, a plurality of dotted patterns 1 arranged in the direction near the long axis of a sectional shape of an electron beam are seen in a series, when astigmatism exists in an electron lens system. Thereby, the long-axis direction of the sectional shape of the electron beam can be easily judged and the judgment of the sectional shape of the electron beam at the time of adjusting astigmatism becomes easy thus improving the accuracy of adjusting astigmatism.

Title: Electrophotographic receptor
Inventor: MIYOUKAN ISAO
IPC: C23C14/00
Filed: 1981-10-27
Abstract: PURPOSE:To obtain a photoreceptor which provides sufficient electric charge holding ability and shape accuracy in an electrophotographic receptor having a photosensitive layer consisting of amorphous silicon by using a metal of a specific coefft. of linear expansion for the substrate of the photosensitive layer. CONSTITUTION:A photosensitive layer of amorphous (a) silicon is formed by a glow discharge method, a sputtering method, etc. on a substrate consisting of a metal of <=10<-5>/ deg. coeff. of linear expansion. The internal stresses of the a-silicon generated by the thermal expansion and cotraction of the substrate owing to the heating in the stage of forming the photosensitive layer and the cooling thereafter are reduced by such formation. As a result, the photosensitive layer having high dark resistance and the charge holding ability necessary for formation of electrophotographs is obtained. Since no large deformations are generated in the substrate, the shape accuracy of the substrate is maintained with virtually no change if said accuracy is made beforehand high. Said accuracy is maintained even after the formation of the a-silicon. The position accuracy with respect to apparatus that execute the respective stages of electrophotographic processes is made high easily.
