Title: Method and apparatus for electron beam lithography
Inventor: GOTO TAISAN
IPC: H01L21/027
Filed: 1988-07-15
Abstract: PURPOSE:To perform ghost exposure in one lithography process by applying a pulse voltage to blanking electrodes as a voltage applied to the blanking electrodes at the time of beam blanking. CONSTITUTION:When a voltage is not applied to blanking electrodes 16, an electron beam is passed through (ON) the blanking electrodes 16 and, when a predetermined voltage (blanking voltage) is applied to the electrodes 16, the beam is blanked (OFF). The predetermined voltage is applied by a blanking voltage generator composed of a pulse voltage generator 17 and a switching circuit 18. The electron beam is continuously applied to a pattern part to be lithographed and is intermittently applied in a form of pulses to a non-pattern part. Therefore, the effective application time (beam dosage) at the pattern part and that at the non-pattern part can be different from each other, so that the correction of a proximity effect which can be performed by a ghost exposure method can be realized. With this constitution, the pattern part and the non- pattern part can be lithographed in one lithography process.

Title: Camera
Inventor: NAGATA TORU
IPC: G03B17/24
Filed: 1992-06-10
Abstract: PURPOSE:To perfectly record photographing order on each frame by arithmetic calculating and recording the photographing order based on the contents of the frame number register of an exposed frame adjacent to respective unexposed frames on a film leader side and a film trailer side and the maximum number of the frames of the film. CONSTITUTION:A controlling circuit 27 arithmetically calculates the photographing order on the film F of the photographing frame based on the contents of two registers, that is, the inside photographing frame number storing register of the exposed frame adjacent to the unexposed frame on the film leader side and the photographing frame number storing register of the exposed frame adjacent to the unexposed frame on the film trailer side and based on the maximum frame number of the film F. The photographing order is written on a magnetic track on the film F through a magnetic head H as one part of camera information. Thus, the photographing order can be perfectly recorded on the film F. Double exposure can be prevented by providing an abnormally detecting means discriminating whether each frame is exposed or not, and setting the result of the detection as 'exposed' when the number of the unexposed frames consecutively detected is equal to or less a specified number.

Title: Closed type burner
Inventor: TOSA YOZO
IPC: F23J15/00
Filed: 1989-07-10
Abstract: PURPOSE:To obtain a combustion gas disposal device which is light in weight and compact by providing a heat absorbing device for absorbing the combustion heat from a burner, cooling device for cooling and liquefying combustion gas, combustion gas storage section, and radiation conversion body for shielding radiation heat. CONSTITUTION:Fuel and oxygen gas are supplied under pressure to a burner 3 through a fuel supply line 1 and liquid oxygen supply line 2. When they burn, the combustion heat is carried to a heat engine by a heat absorbing device 4 and it is converted to power. On the other hand if the pressure in a high pressure vessel 9 is raised by the accumulation of the formed combustion gas and it becomes higher than the saturation pressures of the steam and carbon dioxide at the temperature levels of cooling devices 5 and 6, the respective combustion gases begin to be condensed and liquefied in the cooling devices. The liquefied combustion gas is led to a storage section 7, but the combustion is maintained at the level of pressure at which the amount of the formed combustion gas and its condensation are balanced. As the combustion gas condenses in the cooling devices 5 and 6, the combustion gas flows from the hot zone to the cold zone through a radiation conversion body 8, and at this time most of the sensible heat which the combustion gas possesses is cut by a radiation conversion body 8 so that the heat loss caused by the flow of heat to the cold zone is kept to minimum.
