Title: X-ray tv camera image pickup device
Inventor: YOKOUCHI HISATAKE
IPC: H04N5/225
Filed: 1993-08-16
Abstract: PURPOSE:To prevent deterioration in a photo-conductive film by sensing radiation of an X-ray and controlling a voltage applied to a grid electrode so as to emit electrons from an electron gun of an image pickup tube to the photo- conductive film as an electron beam based on the sensing. CONSTITUTION:When the image pickup finishes, since no incident light onto the photo-conductive film is in existence, a capacitor Cs is charged to 50V by a voltage Vt. Furthermore, a voltage applied to a grid electrode of an image pickup tube 4A is changed to an L voltage and an electron beam is cut off, then the charged voltage of 50V across the Cs is applied to an equivalent resistance Rr of the photo-conductive film. In this case, since a light emitting element 13 is stimulated, the resistance Rt of the photo-conductive film decreases corresponding to the luminous quantity and the stored charged having been charged in the Cs is rapidly discharged. When a 2nd image pickup is made, then a voltage to the grid electrode of the image pickup tube 4A is switched to an H voltage, an electron beam is generated and scanned. Thus, a switch S is closed and the Cs is charged by the voltage Vt and a signal current is generated.

Title: Organic metal vapor growth method
Inventor: ITO HIROMI
IPC: H01L21/205
Filed: 1989-08-05
Abstract: PURPOSE:To eliminate a liquefaction and a solidification of an organic metal compound and to suppress a fluctuation in the growth rate of the compound by a method wherein gas containing the organic metal compound is mixed with carrier gas and the control of partial pressure is performed and thereafter, when the mixed gas is decompressed to put in a reaction chamber and made to perform a vapor growth, the vapor pressure of the organic metal compound subsequent to the decompression is held at the saturated vapor pressure or lower at the temperature of the gas. CONSTITUTION:The saturated vapor pressure of Ca(C2H5)3 which is used in a vapor growth method of GaAs is low and a liquefaction and a solidification are easy to generate by the adiabatic expansion of the Ca(C2H5)3. Owing to this, even in such a case that the temperature of carrier gas is reduced and a liquefaction of a metallic compound vapor is generated, the liquefaction due to a decompression is prevented by ready-reducing a pressure prior to the adiabatic expansion. That is, according to the law of thermodynamics, when specific heat at constant pressure, specific heat in constant volume, a gas temperature and a pressure are respectively set as Cp, Cv, T and P in the case of adiabatic expansion of ideal gas, T/P<(a-1)/a>= becomes constant if Cp/Cv = a. Thereby, a valve 10 is adjusted and the pressure of the flow more upper than the valve 10, that is, the pressure of a pressure gauge 11 is set at a pressure lower than that shown by the second formula.
