Title: Lead frame with insulating tie bar and manufacture thereof
Inventor: NOMURA HIROTOSHI
IPC: H01L23/50
Filed: 1992-05-06
Abstract: PURPOSE:To unnecessitate the cutting of a tie-bar, which is used to stop the flow of resin when the read frame of an integrated circuit is resin-molded and also to maintain the interval of lead, is unnecessitated after the tie-bar has been resin-molded. CONSTITUTION:Tie bars 11, consisting of electrically insulated material, are provided on the outside of a mold line between the leads 9 of the lead frame 1 to be resin-molded. A transfer method is used for formation of insulating tie-bar 11 between the leads 9. As a result, the cutting of the tie bars 11 after resin molding is unnecessitated, and they can be brought into the state of high density by shortening the lead interval when compared with the method heretofore in use requiring the cutting of the tie bar. Also, even in a non-high density state, the breakage of the lead can be prevented by the function of the insulating tie bars as a reinforcement member.

Abstract: PURPOSE:To eliminate contamination and the like to be developed after cleaving a general LD and easily make laser beams coming from many points parallel by causing an active layer to have multi quantum-wells and laser beam emission surfaces to be in disorder to serve as a protective coat. CONSTITUTION:Five laminations for N-type GaAs 22, N-type AlGaAs layer 23, non- doping GaAs, and Al0.2Ga0.8As are performed repeatedly on an N-type GaAs substrate 21 according to a molecular beam epitaxy system and finally an GaAs is laminated, resulting in the formation of active areas 24 having multi-quantum wells. In addition, the above areas make two layers; i.e. P-type AlGaAs layer 25, and P<+> GaAs layer 26 grow in sequence to form Si3N4 according to a plasma CVD. After its Si3N4 in a given area is removed, impurities are diffused to develop a mixed crystal 18 and Si3N4 of the rest is processed by etching in order to form a part applied by an electric current 20 and then, Cr-Au is converted into an ohmic electrode 28 by vapor-deposition and after that, etching is performed to separate its electrode, resulting in the formation of non-impregnation area 19 as a remainder. In the next place, an ohmic electrode 29 for N-type of the rear side is formed and is treated by heating and also a resonance face R making anglestheta1 and theta2 is processed vertically according to a reactive ion etching.

IPC: B60Q1/34
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To prevent a risk of a wrong operation by arranging a direction indicator and a wiper lever to be symmetrical about a steering wheel by projecting a direction indicator lever on both sides of the steering wheel to interlock, and arranging the lever so that the direction indicator lever and the other functions are not similarly operated. SOLUTION: A wiper liable to invite danger due to wrong operation is moved to another place, and a direction indicator lever is extended laterally to interlock. The right and left levers 4 are united in a body under a steering wheel 1 and an air bag 2 to interlock laterally. The levers are not an obstacle to a cowl board 3 and the air bag 2 and have such a strength as to move like a seesaw about a handle shaft. The tips 5, 6 of the levers 4 are turned on the levers 4, so that the light and the wiper function are arranged right and left completely separately in the quite different manner from the operation of the direction indicator. Push buttons 7, 8 are provided to compensate for temporary instantaneous operation such as passing of a light and jetting of a wiper washing liquid.
