Title: Excimer laser device
Inventor: HOTTA KAZUAKI
IPC: H01S3/038
Filed: 1984-09-27
Abstract: PURPOSE:To realize a high-energy, high-efficiency laser with its laser output efficiency kept not lowered in the presence of an increased input by a method wherein discharge electrodes responsible for laser excitation are approximately square in shape. CONSTITUTION:A pair of discharge electrodes 1, 2 for laser excitation and their discharge surfaces 4 are shaped approximately square. For laser excitation, discharge 3 is produced between the discharge surfaces 4 of the electrodes 1, 2. Formation into a square of a discharge electrode means that it geometrically satisfies Lc(length)approx.=Wc(width), which in turn means, virtually, that discharge input density may be lowered even when the longitudinal dimension is smaller in an excimer laser device. An increased input for discharge will not harm uniformity in the discharge, resulting in a high-energy, high-efficiency laser output.

Most of the n-InP layer 15 is removed, whereby a mesa is selectively retained. On top of the mesa, an n<-> - InP layer (third semiconductor layer) 16 is formed. An SiO2 film is formed and then the region along the circumfer ence of the n-InP layer 15 is concentrically removed. After the removal of the photoresist.SiO2 on the wafer, heat treatment is accomplished for the forma tion of a p-InP region 17. This results in the formation of a p-n junction 18 approximating a slant-type junction. Next, an insulating film 21 is formed in the same way and the p-InP region 17 is removed selectively of its internal circumference for the formation of a p<+> - InP region 19. The p<+> - n junction 20 thus formed approximates a single-side junction.

Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To optimize the quantity of heat given to transfer paper and to improve fixing quality by turning off a heat source for a fixed time while the transfer paper is consecutively passing and detecting the temperature change of a fixing roller. SOLUTION: After turning on the heat source, the fixing roller 21 is heated by the heat source 22 and fixation is started when temperature detected by a temperature detection means 23 attains fixation-feasible temperature. After starting such operation, the heat source 22 is turned off for the fixed time while the transfer paper is consecutively passing. Since the heat is not supplied by the heat source 22 during the above, the heat is supplied to the transfer paper only by the heat accumulation of the roller 21. Then, the temperature change (temperature gradient: AM=ΔTM/Δt) caused by the temperature fall for the fixed time at middle nip width between the nip width in a low pressure mode and the nip width in a high pressure mode is set.  When the temperature gradient A at the paper actually passing time shows A<AM, it is judged as the low pressure mode, and in the case of A>=AM, it is judged as the high pressure mode, and a control means adjusts the supply quantity of heat by the heat source 22 so that the quantity of heat given to the transfer paper may be the optimum value.
