Abstract: PURPOSE: To improve the connection between a chip and a bump, by mounting a semiconductor chip on the bottom surface of a box-type base, placing on the base a cap having a bump on its lower surface via bonding solder, melting the solder by heat treatment, and pushing the chip upward while reducing the cross section by surface tension.  
     CONSTITUTION: Semiconductor chip 1 is mounted inside depressed box-type base 1 via melted bonding solder 2. Cap 5 provided on its lower surface control bump 6 via solder heap 7 is placed on either end part of base 1 where bump 6 and chip 1 are kept from coming into contact. Next, the whole structure is subjected to heat treatment, and solder 7 on both end parts is melted and spread, and by lowering cap 5, bump 6 is brought into contact with the surface of chip 1. At the same time, by melting solder 2 placed on the lower surface of chip 1, the cross section is narrowed and the height is increased, and thereby chip 1 is pushed up. In this way, pump 6 in contact with chip 1 is deformed, and the areas of contact between these are made sufficiently large.

Filed: 1986-05-27
Abstract: PURPOSE:To improve the resolution and S/N by varying the frequency of a current for driving an electromagnetic ultrasonic probe and sighting a target space at any time. CONSTITUTION:A transmitting and receiving coil 3 and a power amplifier 6, a variable frequency oscillator 7, a driving mechanism 9, a composite processor 10, a controller 11, etc., are provided. The mechanism 9 moves and sets the probe 5 at a position where x=x0 under the control of the controller 11. Then, the controller 11 sets an oscillator 7 to a specific frequency. Then, the controller 11 supplies a trigger pulse signal to the oscillator 7 to oscillate the sine wave of the frequency. This signal is amplified by the amplifier 6 and supplied to the coil 3 of the probe 5 to generate an eddy current on the surface of a material 1 to be inspected. An ultrasonic wave is generated through the mutual operation between the eddy current and a magnetic field produced by a magnet 4 and propagated in an angle direction where theta=theta0. This ultrasonic wave is reflected by a defective part F and detected by the coil 3, whose signal is sent to the processor 10. This operation is repeated until i=0-(n) and then the processor 10 performs composite aperture processing based on the position xi of the probe 5, etc.

Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To improve the working precision of a cylindrical surface such as cylindricity and surface roughness by specifying the taper ratio of the tapered surface of a rotating member to the tapered surface of a tapered roller. SOLUTION: The tapered roller 2 of a punishing jig obtains a rotating force from a taper pin 7 and revolves around the inside surface of a sleeve 8 while rotating on its own axis within a guide groove. The tapered roller 2 rotates while pressing the inside surface over the whole length of the sleeve 8. Therefore, the bore of the sleeve 8 is extended over the whole axial length of the sleeve 8, and machined with a satisfactory surface roughness. Since the taper ratio of the taper pin 7 to the tapered roller 2 of the punishing jig is set to 2:1, the diameter dimension of the circumscribed circle of the tapered roller extending over the whole length of the sleeve 8 is constant, so that the machining extending over the whole length of the sleeve 8 can be performed.

Title: Reactive power compensating device
Inventor: NISHIKAWA TADASHI
IPC: H02J3/18
Filed: 1986-05-29
Abstract: PURPOSE:To shorten time for waiting from a capacitor making command to output of a gate signal of a thyristor by connecting anti-parallel connected thyristors and a capacitor in series and further connecting a reactor to the capacitor in series and connecting to electric power system. CONSTITUTION:It is supposed that a capacitor making command is given when voltage VC of a capacitor 2 is higher than the peak value of voltage VRS of a power source 5. As no zero crossing point appears in forward reverse voltage detecting devices 4-1 and 4-2 between the anode A and cathode K of thyristors Th1, Th2, the making command is not outputted from a level detecting circuit 10-1. On the other hand, conditions of an AND circuit 15, that is, three outputs from a level detecting circuit 10-2, a voltage peak timing pulse generating circuit 7 and a signal delay circuit 8 are effected, and gate pulses are given to Th1 and Th2, an ignition capacitor current starts to flow. Thus, as the gate signals are given by peak timing of power source voltage and voltage between A-K of Th, the waiting time is shortened.
