Inventor: HIROTA TOSHIYUKI
IPC: H01L33/30
Filed: 1988-03-31
Abstract: PURPOSE:To improve light output and to diffuse heat generated in a light emitting region to the outside efficiently, by making a thin n-type clad layer. CONSTITUTION:An n-type clad layer 2, an active layer 3 and a p-type clad layer 4 are successively formed by epitaxial growth on one side of a semiconductor substrate 1. A p-n junction is formed at a fixed region on the p-type clad layer 4 and a p-side electrode 7 is formed leaving a fixed region whereon the p-n junction is formed. After the semiconductor substrate 1 is processed to a fixed thickness, a section corresponding to the fixed region is removed, and an n-side electrode is formed by filling the part of the fixed region by plating from the other side of the substrate. Since the n-side electrode 8 is arranged at an area near a light emitting region of the active layer 3, heat generated at the light emitting region is diffused effectively to the outside through it. The heat resistance can be thereby reduced equivalently and, therefore, the linear properties of light output can be improved.

On this occasion, a filter 20 is composed of a capacitor Ca and an inductor La to heighten smoothing effect to the switching frequency of the FET 14. A smoothing capacitor of small capacity and small size on the primary side can thus be used.

Title: Impact mechanism of dot printer and manufacture thereof
Inventor: KII TOMONORI
IPC: B41J2/235
Filed: 1985-04-12
Abstract: PURPOSE:To enable the high-speed printing performance of a printing head to be improved by changing a magnetic flux on the contact part of an armature smoothly and subsequently not allowing the effect of a remaining magnetism to be generated. CONSTITUTION:An armature 18 corresponding to a magnet mechanism is actuated by the elasticity of a leaf spring 20 by selectively energizing a coil 17a of each magnet mechanism, and a printing head is caused to print dots and constitute characters with a printing hammer 22. The armature 18 is formed so that under this operating condition, its contact surface is inclined to allow its thickness to increase on the leaf spring side. In addition, the armature 18 is attached in a positional relation-ship to permit the thickest part of the armature and the suction surface of a core 17 on the magnet mechanism to approach or contact with each other. Consequently, the excess characteristics of a magnetic flux in the magnetic channel becomes very smooth, and a delayed response by a remaining a magnetic flux is prevented. Further, almost no shear force is brought to bear upon the leaf spring 20 because of the one close of a rocking motion of the armature 18, but only a bending stress is generated.
