    摘要： An improved semiconductor laser device is provided which has a small distance between laser light emitting spots. Such laser device comprises i) a first light emitting element including a laser oscillation section provided with a ridge waveguide and formed by forming a group-III nitride semiconductor film on a substrate, an insulating layer and an ohmic electrode layer, ii) a second light emitting element including a laser oscillation section provided with a waveguide and formed by forming III–V compound semiconductor film, an insulating layer and an ohmic electrode layer. By virtue of the adhesive metal layer interposed between the two ohmic electrode layers, the two laser oscillation sections are combined together, thereby forming the improved semiconductor laser device which has a small distance between laser light emitting spots of the two laser oscillation sections.

    摘要： The information storage apparatus has an internal structure and arrangement of fans in consideration of the cooling effect. The capacity of the entire apparatus can be smaller than that of a conventional apparatus and an optimum air channel can be formed so as to maintain reliability of performance, life and the like of components at high temperatures. Further, relatively speaking, a module which does not produce a large amount of heat and does not require cooling is provided in a front stage of the channel while a module including heat-producing components and a cooling fan is provided in a rear stage of the channel.

    摘要： An object is to effectively cool down an electronic equipment which is face with height limitations and tends to readily increase in heat generation amount to thereby provide the reliability required. The interior of a chassis of a control unit is partitioned by a back board into a front side space and a rear side space. In the rear side space, two control modules are attached so that these are stacked up and down, while two fan modules and a single duct member are attached in the front side space. Each fan module has two fans as built therein. A cooling air stream or “wind” from each fan flows into the lower-side control module through the duct member and others, whereas a cooling wind from the other fan flows into the upper-side control module. Even when either one of the fan modules goes down during operation, it is still possible by using the remaining fan module to cool down the both control modules.
