Abstract: PROBLEM TO BE SOLVED: To obtain excellent electrification characteristics, stable max. image density, low fog, high resolution, and good low temp. fixing property and offset resistance by controlling the saturation water adsorption amt. and the water adsorption rate of a toner into specified ranges. SOLUTION: The saturation water adsorption amt. and the water adsorption rate of a toner are controlled to <=1.0wt.% and >=0.2wt.%/hour, respectively. The saturation water adsorption amt. means the amt. of water in terms of wt.% adsorbed during a toner is left to stand for 24 hours at 30 deg.C and 80% RH. The water adsorption rate is determined by measuring the water adsorption amt. (A) (wt.%) when the toner is left to stand for 24 hours at 20 deg.C and 50% RH, then further leaving the toner to stand for 1 hour at 30 deg.C and 80% RH, measuring the water adsorption amt. (B) (wt.%), and calculating (B)-(A) (wt.%/ hour). When the water adsorption rate is less than 0.2wt.%/hour, such a problem may occur that the toner can not follow changes in the temp. and humidity in a machine.

Title: Semiconductor laser
Inventor: AOYANAGI TOSHITAKA
IPC: H01S5/00
Filed: 1989-03-27
Abstract: PURPOSE:To obtain a semiconductor laser which oscillates with a low threshold by a method wherein impurity is diffused from a surface layer side or a crystal substrate side to a depth middle of a lower cladding layer or an upper cladding layer so as not to reach a light emitting part to form a region whose conductivity type is opposite to that of the lower cladding layer or the upper cladding layer in the lower cladding layer or the upper cladding layer. CONSTITUTION:An n-type Si diffused region 10 is formed to a depth middle of a p-type AlxGa1-xAs lower cladding layer 4 by diffusing Si from a surface side to form p-n junctions 11 having high built-in potentials in the p-type AlxGa1-xAs lower cladding layer 4. As the potential barriers are higher than the potential barriers of p-i-n junctions formed between an undoped AlyGa1-yAs active layer 5 and upper and lower cladding layers 6 and 4 in a bent part, ineffectual currents 9 are hardly injected into the flat parts on the sides. In other words, the ineffectual currents 9 are blocked by the p-n junctions 11 formed in the upper and lower cladding layers 6 and 4 and effective currents 8 only are injected into the bent or warped part. With this constitution, a semiconductor laser which oscillates with a low threshold current can be obtained.

Thus, the learner learns the braille by himself through the perception of braille on the sheet 1 and the audio output. Since the sensor 4 identifies the sheet number, plural braille sheets 1 are used and many texts are used for the braille study.
