Title: Lead frame with oxidation resistant nickel plating resistant to release of solder
Inventor: SOEDA MASUMITSU
IPC: H01G4/228
Filed: 1986-06-11
Abstract: PURPOSE:To contrive improvement in resistance to release of solder by a method wherein the outside layer of double layer plating is thickly formed. CONSTITUTION:When a soldering work is performed, an Ni-Sn alloy layer is grown on the contact interface between Ni plating and solder, and its thickness reaches 0.1-0.3mum. Then, the alloy layer is increased to 0.3-0.5mum or thereabout by the thermal variation with time after soldering. When the thickness of the alloy layer reaches the interlayer of double layer plating, an interlayer exfoliation is generated due to the stress concentration between layers. Accordingly, the release of solder can be prevented completely by forming the plating thickness of the outside layer thicker than the thickness of 0.3-0.5mum at which the Ni-Sn alloy layer can be grown. Besides, the desired upper limit of plating thickness is 2.0mum or smaller taking into consideration of an economical reason. Therefore, the improvement in resistance to release of solder of the lead frame can be achieved by forming the oxidation-resistive Ni alloy plated layer in the thickness of 0.7-2.0mum.

Title: Fixed position stopping method of carrier in linear motor carrying system
Inventor: HAMAGUCHI SANAI
IPC: H02P7/00
Filed: 1990-05-28
Abstract: PURPOSE:To stop a carrier reliably at a fixed position at all times by down counting a set positioning amount, loaded with an output value from a speed sensor, thereby producing a speed command value to be fed to a drive power supply. CONSTITUTION:When a carrier 2 travels and arrives at the area of LIM1, a position sensor in a sensor unit SS1R produces a position signal Sp and a speed sensor starts outputting speed signals SA, SB. Consequently, a difference counter 13 starts down counting input pulses from a set positioning amount Q. Count in the difference counter 13 is converted through a D/A converter 14 into an analog signal which is then fed, as a speed command SKX, to a drive power supply 5. The drive power supply controls the driving voltage according to the difference between the speed command SKX and the speed signal fed from the speed sensor in a sensor unit SS2F. When the number of input pulses become equal to the set amount Q, the speed command value goes zero and the carrier 2 stops smoothly.

Filed: 1995-06-05
Abstract: PURPOSE: To provide a memory circuit for users in which readout failure at the time of the power source voltage drop is avoided by supplying a raised power source voltage to the sense amplifier circuit. CONSTITUTION: When the power source voltage drops, the sense amplifier circuit 18 on the side of memory transistor group 16 as memory circuit for users approaches the lower limit of its regular readout operation range. And failure occurs in the readout of data of '1' at a sense amplifier circuit 1F on the side of monitor memory circuit 1C where the lower limit is higher than the side of the circuit 16, and a value different from the expected one is read out. As the result, an expected value judging circuit 1G outputs a signal L announcing the approach to the lower limit of regular operation range on the side of the circuit 16 at the rising time of E signals, system clocks, and is inputted into a booster circuit 41 through a line 1H. During the period of outputting this signal L, a voltage twice the usual power source voltage is supplied to the circuit 18 as power source voltage.  Through this, the narrowing of the variation width of the bias voltage, which is one factor to cause readout failure by drop of power source voltage is restored, and thereby the margin of readout operation of the circuit 16 at the time of low voltages is improved.
