IPC: H01L21/027
Filed: 1998-08-13
Abstract: PROBLEM TO BE SOLVED: To enlarge a current amount of a charged particle beam so as to enhance a throughput by reducing blur and distortion caused by coulomb effect. SOLUTION: A shaping aperture 4 is irradiated with an emitted electron beam 2 from an electron source 1 by operation of a first irradiation lens 31. The passed electron beam 2 through the shaping aperture 4 forms an image of the shaping aperture 4 on a reticle 5 by operation of a second irradiation lens 32 and a third irradiation lens 33. The passed electron beam 2 through the reticle 5 passes through a first projection lens 61, is bent in its trajectory by astigmatism correctors 91, 92, 93, 94, and finally, forms an image of the reticle 5 on a wafer 7 by operation of a second projection lens 62. The astigmatism correctors 91, 92, 93, 94 generate astigmatism near a crossover point so as to prevent reduction of an area of the electron beam 2. Thereby, the coulomb effect is reduced, and the current amount can be increased so that the throughput is enhanced.

Title: Image forming device
Inventor: HOSHI AKIMITSU
IPC: G03G15/00
Filed: 1993-09-14
Abstract: PURPOSE:To satisfactorily demonstrate the capability of a machine and to increase the copying speed when the image density is low by performing the image forming while changing the distance between papers in feeding the paper corresponding to the detected image density of an original and hardly changing the mechanical constitution. CONSTITUTION:When the copy starting key is pushed on setting a bundle of the original 2 to the original transporting device 1, the original 2 is transported onto the platen glass 21 by the original transporting device 1 while measuring the image density of the original by the image density detecting sensor 4. Then, the image density is reaffirmed by performing prescanning, reading of the original 2 with the CCD 3 and the potential sensor 5, and finding out the average value of the image density. Next, when the value of the image density read out is <=7%, the condition setting is made by selecting the short distance between the papers by judging that the original is primarily composed of character information such as the typescript original. Then, when the image density is high, the condition setting is made by selecting the low copying speed, namely the standard distance between the papers by assuming the worst condition as in the conventional manner since the fixing quality is unstable.

Title: Calorimetric unit and method
Inventor: KAJI KAZUTOSHI
IPC: G01N25/20
Filed: 1991-09-09
Abstract: PURPOSE:To provide a calorimetric unit and method whereby the heat capacity of trace amounts of samples can be measured with high accuracy. CONSTITUTION:In the sample container 1 and the heat insulated container 7 of an insulated calorimeter which can measure the heat capacity of material with high accuracy, a temperature sensor 8 is provided to the heat insulated container 7 which is so controlled to be at the same temperature as the sample container 1. A thermocouple 6 detects the temperature difference between the insulated container 7 and the sample container 1 and a calorimetric circuit is used which employes as sample temperature the temperature of the insulated container 7 at which the temperature difference becomes zero. The temperature sensor can thus be excluded from the sample container 1 and the heat capacity of the sample container 1 can be lowered so that trace amounts of samples can be measured. Furthermore, errors in measurements are reduced since heat conduction from the sample container 1 is reduced.
