Abstract: PURPOSE:To improve index waveguide characteristics without deteriorating characteristics by working damage, and to scale down a far-field patten by forming an optical guide layer to the upper section of an active layer in a ridge waveguide type semiconductor laser and executing mesa working up to a section near the optical guide layer. CONSTITUTION:An N<-> type AlGaAs clad layer 10, an AlGaAs optical confinement layer 9, a multiple quantum well structure (MQW) active layer 8, an AlGaAs optical confinement layer 7, a P-type AlGaAs clad layer 6, an MQW optical guide layer 5, a P-type AlGaAs clad layer 4 and a P<+> type GaAs cap layer 3 are shaped onto an N<-> type GaAs substrate 12. The composition and thickness of each layer are brought so that light waves propagated through the active layer 9 and the optical guide layer 5 are coupled mutually. An SiO<2> insulating film 2 and electrodes 1, 13 are applied after ridge working. Since a mesa working surface on the outside of a ridge is separated sufficiently from the active layer, damage at the time of working has no effect on the active layer. Since an index guide type is formed, astigmatism is removed, and an output can be increased.

Filed: 1991-11-25
Abstract: PURPOSE:To provide a line thermal head protection circuit which can correspond to various kinds of abnormal situations, self-reset errors and carry out normal printing after self-resetting errors. CONSTITUTION:The variation of head load signal S2 output from a power-on control circuit 14 is sensed by a flip-flop FF1 and a NAND gate G3. If the variation is not sensed during the given time (error), error signals $6 are output by a counter CT1 and an inverter INV2, and the power-on control circuit 14 is reset by a reset signal S8. An error signal S5 is output by the flip-flop FF2 during said reset period to put a control terminal of the gate G2 on H level and put forcibly a power-on control signal S1 on H level, which means power- off. A thermal head, therefore, is protected.

Title: Cutting method for titanium alloy
Inventor: ISOGAWA YUKIHIRO
IPC: B23D15/00
Filed: 1987-12-28
Abstract: PURPOSE:To make an efficient shearing method having little deformation of a cut surface and no reduction in yield by weight possible by forming a notch in a cutting position of a titanium alloy material by pushing of a wedge tooth material or sawing, and then adding a shearing force to said notch. CONSTITUTION:A notch cutting edge 4 is provided in a determined position before a shearing cutting tooth composed of a moving cutting edge 2 and a fixed cutting edge 3. After forming a notch 5 in a cutting position of a bar of titanium alloy by said notch cutting edge 4, the bar 1 is shifted to the right and the moving cutting edge 2 is lowered followed by shearing processing. In this case, one notch is sufficient, but as occasion demands, the notch may be formed in two positions or more, for example on the both sides of the bar. The thus preliminary formation of the notch in the position to be cut the titanium alloy material provides selective cracks from the top end of the notch nearly toward the shearing direction in the shearing processing. This allows a reduction in inclination of the cut surface, resulting in a reduction in cutting load, so that the load of the shearing cutting edge can be reduced and also the formation of the burr can be restricted.

Abstract: PURPOSE:To obtain a metal electrode with no part overhanging the peripheral part of the upper surface of a mesa structure by a method wherein a mesa etching is carried out using a silicon nitride film pattern as a mask to form a mesa structure provided with an upper peripheral part overhanging like a peak taking advantage of an etching rate difference between a P region layer and a high resistive region layer. CONSTITUTION:A silicon nitride film 7 pattern is formed on a P region layer 3, and a silicon substrate is etched using the pattern concerned as a mask. In this case, a part overhanging like a peak is formed on the upper peripheral part of a mesa structure due to an etching rate difference between the P region layer 3 and a high resistive region layer 2. In succession, a silicon oxide film 6 is formed on a part other than the part covered with the silicon nitride film 7 through thermal oxidation, and then the silicon nitride film 7 is removed by hot phosphoric acid. A Pd metal layer 8 is formed on the whole face of the mesa structure through an evaporation method. Then, the mesa structure is sintered to form an Si-Pd eutectic layer 9 on the bonded part of the pd metal layer 8. Moreover, a Cr/Pt/Au metal layer 10 is vertically evaporated on the Pd metal layer 8. The Pd metal layer 8 and the Cr/Pt/Au metal layer 10 are fully cut off at the peripheral part which overhang like a peak, so that no part overhangs the peripheral part.
