Title: Lead frame for semiconductor device and semiconductor device using the same
Inventor: NAKANO TADAAKI
IPC: H01L23/50
Filed: 1992-07-02
Abstract: PURPOSE:To improve the bonding between bonding wires and a lead frame and between the lead frame and resin by forming corrugations at the free end portions of a plurality of leads. CONSTITUTION:An etching step or press step of forming corrugations, grooves parallel to the lead pattern or through holes at the distal end portions of inner leads 4, is added to the process for fabricating lead frame 7. With this lead frame 7 used in a semiconductor device, pressure-bonded portions between bonding wires 6 of Au, Al or the like and the lead frame 7 have heavy pressure- bonded portions and light pressure-bonded portions. As a result, the bonding between the bonding wires 6 and the lead frame 7 is enhanced, preventing the wires 6 from being cut due to a slight environmental change. Because of this shape of the lead frame 7, the surfaces of the inner leads 4 become rougher to improve the bonding between the lead frame 7 and resin. The lead frame 7 therefore is not affected by an environmental change and have a high reliability.

Title: Automatic transmission
Inventor: IDOGUCHI MASARU
IPC: B60W10/10
Filed: 1985-08-09
Abstract: PURPOSE:To make a clutch so as not to be disengaged and an engine brake so as to be applied in succession even if an accelerator pedal is restored during starting motion at a downhill, by keeping on with a clutch engagement in the case where an engine speed fails to drop even if the accelerator pedal is restored during the starting motion. CONSTITUTION:In the midway of starting motion, when an accelerator pedal 24 is restored before a clutch is completely engaged, a microcomputer 21 detects the rotational frequency of an engine 10 with an engine speed sensor 27. And, when the engine speed goes down, it judges that a driver discontinuous the starting, whereby the clutch is disengaged by an actuator 19. However, when the engine speed fails to drop, starting control comes to be continued so that the clutch is not disengaged. Therefore, at the time of starting a car at a downhill, even if a drive's foot comes off the accelerator pedal before the clutch is completely engaged at the midway of starting motion, the microcomputer 21 is not so judged that the driver discontinues the starting, engaging the clutch, and it keeps up with the starting control.

Abstract: PURPOSE:To produce within a short period of time a semiconductor element equipped with a desired area and mesa geometry by a method wherein a mesa groove is provided in one side or both sides of a semiconductor wafer before it is segmented into elements along the mesa groove. CONSTITUTION:A semiconductor wafer 1 coated with resist film 2 is placed in a mixed acid. The acid attacks the semiconductor wafer 1, whereby a mesa groove 6 is formed due to the etching effect. In the same process, a through connection is established between a groove 7 shaped after a linear pattern 5 and a groove 8 originating in a dicing groove 3 for the separation of a semiconductor section 11 outside the linear pattern 5, also due to the etching effect. After the separation, etching is stopped. Dicing or bending along the mesa groove 6 results in the segmentation of the semiconductor wafer 1 for the production of a semiconductor element. This method ensures uniform depth for a mesa groove by short-period application of etching for the realization of a semiconductor element equipped with a desired area and mesa geometry.

Filed: 1986-07-25
Abstract: PURPOSE:To generate laser oscillation on various quantum levels, by forming an internal-loss-modulation part of a resonator, where a reverse bias is applied to the layer in the same structure as the layer into which gain current is injected, in a semiconductor laser having an active layer of quantum-well structure. CONSTITUTION:A semiconductor laser element having an active layer 4 of quantum-well structure, is provided with an electrode 8 which is used so that a reverse bias is applied to the same layer B in the same structure as the layer A into which gain current is injected. Therefore, the voltage applied through this electrode is controlled to increase the internal loss selectively in conformity with oscillation frequency, so that laser oscillation on high quantum levels can be generated. Besides, this control enables oscillation wavelength to be easily switched. Though the loss-modulation part B is being formed on the one-sided laser terminal plane, its formation becomes effective similarly on the central part.

Title: Ignition device of internal-combustion engine
Inventor: OKAMURA KENJI
IPC: F02B75/02
Filed: 1981-11-05
Abstract: PURPOSE:To always obtain stable ignition performance in no relation to an operational condition, by decreasing influence of a swirl flow through a windbreak protrusion and providing said windbreak protrusion in the vicinity of a spark plug in the upstream of a spark gap for the swirl flow in a combustion chamber. CONSTITUTION:If a mixture, flowing in through an intake port 3, is sucked into a combustion chamber 2, a strong swirl is formed, and this swirl is left existing to the latter half of a compression stroke to still contain a strong swirl component residual in ignition timing immediately before the top dead center. On the contrary, a strong wind by the swirl is not generated in the vicinity of a spark plug 5 through a windbreak protrusion 7, and a stable electric discharge can be always obtained between a center electrode 11 and outer electrode 12 to surely perform firing. If the firing is once performed, a swirl flow, colliding against the windbreak protrusion 7 to generate fine turbulence of air, causes a flame to spread in the swirl flow while increasing a combustion speed, and the combustion speed is increased cooperatively with a component of the turbulence, then high speed combustion can be surely performed also in a strongly swirled condition.
