IPC: H01L21/027
Filed: 1983-10-18
Abstract: PURPOSE:To obtain a positive type resist film having a sufficient function to dry etching or ion implantation without thickening the thickness of the resist film by projecting electron rays to the resist film applied on the surface of a semiconductor substrate, developing the resist film to form a predetermined pattern and projecting electron rays to the whole again in the quantity of exposure larger than that in case of the formation of the pattern. CONSTITUTION:A positive type resist film 2 in approximately 1.0mum thickness is applied on the surface of an Si substrate 1 and dried, electron beams 4 are projected to a predetermined pattern section 3, and another pattern forming section 31 in the vicinity of the section 3 is irradiated by electron beams 41 while being scanned. The total amount of beams projected is brought to approximately 1X10<-5>coul/cm<2> at that time, and the sections 3 and 31 are developed with ethyl acetate, etc. to remove irradiated sections. Electron-ray showers 5 are projected to the whole surface for approximately 100sec while bringing the total amount of beams to approximately 1X10<-3>coul/cm<2>, and the cracks, deformation, etc. of the previously obtained resist film 2 are removed, thus acquiring a fine pattern.

Title: Character recognizing system for plural character systems
Inventor: NAKADA AKIRA
IPC: G06F9/45
Filed: 1989-07-26
Abstract: PURPOSE:To process plural character systems with one module by constituting a system so that a word analysing part uses a corresponding character attribute table to recognize the attributes of input characters at the time of input of a source program. CONSTITUTION:The value of a character to be recognized is not held in a word analysing part 12 but is processed in accordance with the attribute to be recognized, and the correspondence between the value of the character and the attribute is held in a character attribute table 10. A word analysing part 12 refers to the character attribute table 10 just after reading one character and gets the character attribute to perform the processing of character recognition. Consequently, the processing of the word analysing part 12 is dependent upon only character attribute tables 10 in the case of processing of plural character systems. Thus, character attribute tables 10 are switched by a control module 11 to recognize characters of plural character systems by the same word analysing part 12.

Title: Organic el device driving method
Inventor: TADA HIROSHI
IPC: H05B44/00
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of a device with a simple driving device and to lengthen the driving life of the device by applying sine wave AC voltage to a part between an anode and a cathode to drive the device. SOLUTION: An organic EL device is a current injection type device, and emits light by the recombination of a hole and an electron in a luminescent region when a charge is injected. When the organic EL device is continuously driven, the resistance of an organic film is increased and current hardly flows, and if driving condition is specified by voltage, current is decreased in continuous driving, drop in brightness is accelerated. Control of driving condition by current value is effective. As the method for it, a current value is detected, the current value detected is fed back to a peak voltage value of sine wave AC voltage applied to between an anode and a cathode. The peak voltage value can be manually controlled, but it is controlled with a driving circuit, for example, so that an integrated value or an average value of current is made constant.
