Patent JP-H0449870-A (JP)
Title: Semiconductor output circuit
Inventor: TATEYAMA TAKESHI
IPC: H02M7/537
Filed: 1990-06-19
Abstract: PURPOSE:To prevent the breakdown of a MOS transistor or a lead wire by overcurrents by providing an overcurrent detection means between the low voltage power terminal of a H-type bridge connection and the low voltage power source, and inputting the signal detected by the overcurrent detection means so as to clamp a gate control signal and break the transistor on high voltage side. CONSTITUTION:In case that load RL goes wrong and the division between output terminals M and N shorts, or that excessive voltage adds to a power terminal 7 and excessive currents flows to load resistance RL or a power terminal 9, the detection voltage VR at overcurrent detection resistance 16 rises. The current flows to an NPN transistor base, too, and turnes on transistors 5 and 6, and lowers the voltages of gate control signals S1 and S3 on high voltage side, and turns off the MOS transistors 1 and 3 on high voltage side, and prevents the excessie currents which flow to the load resistance RL of output. Hereby, the breakage of a MOS transistor and the fusion of a lead wire which connects it with the lead frame of a chip can be prevented.

IPC: H01L27/04
Filed: 1990-06-19
Abstract: PURPOSE:To prevent the diffusion of impurities from an accumulating electrode to a diffusion layer and micronize it for speedup and high integration by forming a film of barrier material between the diffusing layer and the accumulating electrode. CONSTITUTION:A field oxide film 2 for element isolation is formed on a P-type silicon substrate 1, and a gate electrode 3 consisting of polysilicon is formed through a gate oxide film 2a. A first diffusion layer 4 is formed in a self alignment manner for the gate electrode 3, and an accumulating electrode 6 consisting of polysilicon 2000Angstrom  thick is formed for the first diffusion layer through a barrier material 11. The barrier material 11 is a silicon nitride film 40Angstrom  thick, which is obtained by heating it in NH3 atmosphere after forming an opening in a first interlayer insulating film 5a. By catching this barrier material 11, even if, for example, phosphorous is diffused, as impurities, enough until the layer resistance becomes 20OMEGA/port, it never diffuses to the P-type silicon substrate 1.

IPC: B05B5/04
Filed: 1978-12-22
Abstract: PURPOSE:To make the thickness of a paint uniform, by inclining the liquid paint filming surface of a rotary disc in the opposite direction to a paint receiving part. CONSTITUTION:A disc 8 is rotated by a rotary driver 2. A high voltage is applied to the disc 8 at the opposite polarity to a painted piece. A paint is supplied from a tube 4 into a paint receiving part 8a. The paint flows out of the receiving part 8a onto a liquid paint filming surface 8b due to the centrifugal force of the disc 8. The paint then flows toward a peripheral part 8c due to the centrifugal force F of the disc and is thrusted on the filming surface 8b by the vertical component of the  centrifugal force so that the paint is made into a uniform thin film, which has the  smallest thickness on the peripheral part 8c. As a result, almost uniform liquid  threads are projected toward the painted piece.
