Title: Image pickup device
Inventor: MAEDA TETSUO
IPC: H04N5/335
Filed: 1988-02-29
Abstract: PURPOSE:To reduce the number of image pickup elements and to improve the resolution by applying one scanning to an output of a photosensing element every time the position of the image pickup element is moved by 1/N each of the interval of individual photosensing elements with respect to an external object, that is, in total N times thereby substantially obtaining a multiple of N of the resolution. CONSTITUTION:One scanning is applied at first with no voltage applied to a piezoelectric element. In this case, the image of the external object 3 with respect to the real image on the image pickup element 1 is converted into an electric signal with a resolution of P1 longitudinally and P2 laterally. Then a voltage is applied to the piezoelectric element 4 to move the image pickup element 1 by Px1/2 longitudinally. In this state, the 2nd scanning is applied. The data between photosensitive elements not obtained in a 1st scanning is obtained by a 2nd scanning and the longitudinally twice resolution is realized by synthesizing the data obtained by the 2nd scanning with data obtained by the 1st scanning. Thus, the longitudinal two-fold resolution is realized in comparison with a conventional device.

Filed: 1991-02-21
Abstract: PURPOSE:To eliminate a common start-up switch in a parallel type switching power circuit and to make an accurate start-up only with operation of individual power switch of each constituent unit. CONSTITUTION:Start-up signal input terminals I1, I2 and drive stopping signal input terminals R1, R2, of switching power supply parts 12, 22 become active when connected to a minus side of an input power supply 31.

When a power switch 16 is turned on, I1 becomes active and R1 is held active, too, and the start-up conditions are not satisfied. Therefore, first and second switching power supplies 15, 25 do not start up. When a power switch 26 is turned on, I2 becomes active and R1 and R2 become inactive and the start-up conditions are satisfied. Therefore, the switching power supplies 15, 25 start up simultaneously.

As for said electrons, since (+5KV) is impressed upon the cathode and (+10KV) is impressed upon the anode 12 respectively, the electrons can obtain kinetic energy of 5KeVK, and can proceed in the sample surface direction. Since the positive potential (+5KV) is held by the sample 2, the electrons are decelerated by means of the stopping electric potential between said anode 12 and the sample 2, and can reach the vicinity of the sample surface at approximately OV, and can form electron cloud in the vicinity of said sample surface. When the sample surface is charged up, the electrons corresponding to the charge-up degree can be supplied to the sample surface.
