Title: Semiconductor laser element
Inventor: TANETANI MOTOTAKA
IPC: H01S5/00
Filed: 1987-09-24
Abstract: PURPOSE:To prevent an oscillation light from being reabsorbed and a crystal from deteriorating by extending a transition region of a semiconductor substance ratio formed between a first semiconductor layer of a light emitting layer and a second or third semiconductor layer of a clad layer as compared with the interior of an element near at least one light irradiating end. CONSTITUTION:When a light emitting unit 100 is irradiated with a light of an argon ion laser from the front face of a semiconductor laser element, the vicinity of the unit 100 rises its temperature, an active layer 104 and clad layers 103, 105 are mixed with each other, and its boundary region is extended. Then, a transition region of aluminum mixed crystal ratio between the layers 104 and 103 and between the layers 104 and 105 is increased. Thus, the crystal mixture ratio in the layer 104 becomes high in average, and the distribution of a forbidden band width in a resonator direction is widened at the front end face of the resonator. The wide section of the forbidden band width is transparent for the oscillation light, and the reabsorption of the light for causing its deterioration does not occur.

Title: Image recorder
Inventor: DOI ATSUHIRO
IPC: G03D13/00
Filed: 1988-09-27
Abstract: PURPOSE:To improve accuracy in overlapping a photosensitive material, on which an image is exposed, with an image receiving material and to reduce cost by providing first and second driving means which separately and independently drive first and second carrying means, respectively, according to the timing to overlap the photosensitive material with the image receiving material. CONSTITUTION:Two carrying means, which carry the photosensitive material 16 and the image receiving material 32, are driven separately and independently by using the first and second driving means, respectively; without such a means as a clutch, each carrying means is driven without delay according to the timing to overlap, so that each material is carried. This prevents the dislocation of the position in which both carried materials are overlapped. Since each driving means is independent, the change of a load accompanied by activating one of the driving means does not affect another driving means, and each material can be carried at the constant speed. Additionally, an expensive part such as a clutch is not required, therefore cost can be reduced.
