Title: Electron image transfer process
Inventor: YASUDA HIROSHI
IPC: H01L21/30
Filed: 1985-02-13
Abstract: PURPOSE:To prevent the electron generating-efficiency of a mask from deteriorating by a method wherein an electron image is transferred from a mask to a specimen corresponding to a mask pattern by irradiating a mask film while the mask is supplied with filming material within the same vacuum vessel. CONSTITUTION:A mask pattern 3 is formed on the surface of substrate 2 in a vacuum vessel 1. Next a film 4 made of Cs etc. of a mask 5 covering the mask pattern 3 is irradiated with light 7 emitted from a light source 6 to radiate electrons 8 from the mask 5 transferring an electron image to a specimen 9. At this time, a film material source 10 such as Cs etc. is provided in the same vacuum vessel 1 to supply the surface of mask 5 with the filming material such as Cs etc.

IPC: H01L21/205
Filed: 1987-02-06
Abstract: PURPOSE:To reduce difference in film thickness to be formed by providing a concentric-circular slit on the peripheral part of a susceptor to be leaded with a sample for unifying a surface temperature of the sample. CONSTITUTION:A susceptor 1 loaded with a sample 2 is held by a holding rod 5a the susceptor 1 is red-heated by high frequency inductive heating for holding the sample 2 at a prescribed temperature. At the time, the peripheral circular part not loaded with the sample 2 of the susceptor 1 is provided with four concentric-circular slits 1a. Then, radiation heat per unit area radiating from the peripheral surface parallel to the opposing sample 2 is reduced as compared with the case of no slit 1. As a result, difference in the surface temperature in the peripheral part and the central part of the sample 2 is compressed so as to reduce difference in film thickness to be formed.

Title: Stepup chopper device
Inventor: MIYAZAWA YOSHIAKI
IPC: H02M3/10
Filed: 1984-02-16
Abstract: PURPOSE:To separate a stepup chopper unit which malfunctions by flowing a discharging current of a smoothing condenser through a fuse due to the malfunction to melt the fuse. CONSTITUTION:When a semiconductor switch 103 continues ON state due to the erroneous operation of a controller and a DC input current Id abruptly increases, an overcurrent detector 134 is operated to apply a gate signal to a thyristor 32. Thus, the current of the condenser 105 starts discharging, the discharging current rises at an ingredient determined by the wiring inductance, and when the fuse 131 starts melting, the current limit is simultaneously started to complete the interruption of the fuse 131. Thus, almost no variation occurs at a common DC power source voltage for the malfunction of one chopper, and a disorder cannot be applied to the other healthy choppers.

Title: Solid-state image sensing device
Inventor: WATANABE YASUSHI
IPC: H04N5/369
Filed: 1989-02-03
Abstract: PURPOSE:To suppress a monitor-picture upper-side white smearing phenomenon, etc., at a time when the partial or all picture-element signals of the light- receiving section horizontal transfer section side are discharged to a horizontal transfer section by successively forming a potential barrier region controlled by a horizontal transfer electrode and a drain region on the opposite side of a light-receiving section while being brought into contact with a horizontal transfer region. CONSTITUTION:A potential barrir region PB and a drain region PD are shaped successively brought into contact with the opposite side of the connecting side with the light-receiving section of the horizontal transfer region 1 of a solid-state image sensing device, and the transfer electrode of a horizontal transfer section is extended on the potential barrier region and the surface of the drain region PD through an insulating film. Even when signal charged more than the transfer capacitance of the horizontal transfer section are transferred from a vertical transfer section 3, excess charges are made to flow out to the drain region PD. Accordingly, the adverse effect of a white smearing phenomenon, etc., due to the overflowing of charges in the horizontal transfer direction is prevented.

Patent JP-H03231274-A (JP)
Title: Image forming device
Inventor: WAKI KENICHIRO
IPC: G03G15/16
Filed: 1990-02-07
Abstract: PURPOSE:To obtain a good transferring and separating performance by controlling the amount of current of a means which feeds the transferring charge to a transfer belt according to the amount of current flowing in plural supporting rollers on which the transfer belt is hung, and controlling the amount of current flowing in an image carrier side to an appropriate value regardless of any change in the environment. CONSTITUTION:The amount of current fed to a controller 12 through supporting rollers 111 to 113 is measured, the current IT output from a power source 13 is increased by just the increased amount of this amount of current, and a separation failure such as the transfer material being wrapped to a photosensitive body drum 1 is not generat ed. On the other hand, under low temperature, low humidity, although the transfer belt 2 becomes dry and its volume resistivity is increased, an appropriate amount of current fed to the photosensitive body drum 1 side is secured, and transfer failure due to deficient amount of current is not generated. Furthermore, when a transfer material on which it is difficult to carry out transferring is passed through, since the amount of current fed to the photosensitive body drum 1 side is secured to be an appropriate value, transfer failure and separation failure is not generated. Thus, transferring and separation can be carried out well.

Thus, the overvoltage of the gate of the MOS TR 4 is prevented.
