Title: Resin sealing type semiconductor device
Inventor: OKIKAWA SUSUMU
IPC: H01L23/31
Filed: 1980-06-23
Abstract: PURPOSE:To increase a packing effect and to improve dampproof property by having a constitution in which at least a soft metal film is sealed in resin. CONSTITUTION:Around the element section of a lead 1, on which a semiconductor element 3 is connected, a soft metal film 2 such as silver, lead or the like is partially formed, and this film 2 is sealed with resin 5 so that the film is not exposed to the outside. By providing the soft metal film 2 on the surrounding section of the element as above, the dampproof qualities can be improved thoroughly, because the moisture infiltrates from the outside. also, when a shearing stress is generated on the interface of the resin 5 and the lead 1 due to the disagreement of the thermal expansion coefficients of the resin and the lead 1, the contracting resin 5 is pressed on the side of  the film 2 by its contractive force, thereby stopping the contraction of the resin 5.  Besides, the shearing stress is absorbed by the film 2 and the packing effect is increased because of the improvement in the degree of adhesion or fit between the  resin 5 and the film 2.

Title: Storing method of signal of start fault of dc motor
Inventor: HORIE HIDEO
IPC: H02H3/093
Filed: 1990-03-30
Abstract: PURPOSE:To shorten a time required for re-making of a power source in such a degree as no inconvenience being felt on the occasion of a faulty start, by a method wherein a motor current is converted into a voltage and impressed on a first low-pass filter and an output thereof is impressed on a second low-pass filter of which the time constant is smaller than that of the first low-pass filter and longer than that of a reference voltage rise time. CONSTITUTION:When a faulty start occurs, a motor current rises sharply and the voltages V1 and V2 of low-pass filters L1 and L2 rise equally. When the voltage V2 becomes larger than a reference voltage Vr, an output Vout of a comparator C turns to be a logic value H and the comparator delivers a faulty start signal. Therefore a protective circuit operates and the motor current turns to be zero. At the same time, the output Vout of the comparator C is fed back positively onto the input side, the voltage V2 is kept higher than the reference voltage Vr and the faulty start signal is left in a stored state. When a power source is broken, the voltage V2 lowers sharply by discharge at a small time constant and becomes equal to the voltage V1. Since the voltage V1 is set to be lower than the reference voltage Vr, the voltage V2 does not exceed the reference voltage Vr even when the power source is made again, and thus the faulty start signal is not generated.
