Title: Operation control method of inverter refrigerator
Inventor: CHOI O BONG
IPC: F25D11/00
Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To reduce noises and the consumption of electricity which are caused during the operation of an inverter refrigerator by determining the operation frequency of a compressor motor by detecting the operation pattern of the compressor motor conforming to a load thrown into the refrigerator, and controlling the revolution of the compressor motor by the operation frequency. SOLUTION: In an initial stage t0, a compressor motor rotates at a revolution number which is equivalent to an operation frequency, 60 Hz, of a high frequency, and the temperature in the refrigerator is lowered, and at a point t1 wherein the detected temperature in the refrigerator is lower than a set temperature, the rotation of the compressor motor is stopped. Then, as time passes, when the detected temperature in the refrigerator becomes higher than the set temperature again, from a point t2, the compressor motor rotates again. At this time, a microcomputer compares an off time t1-t2 of the compressor motor and a compressor motor off time tOFF which is set in advance, in order to determine the operation frequency of the compressor motor, and then, by judging that a load amount in the refrigerator is large, makes the motor rotate.  By this constitution, operation noises and the consumption electricity can be reduced.

IPC: H03K3/356
Filed: 1993-12-29
Abstract: PURPOSE:To attain speeding up by shortening setup time, by constituting an FF by a clocked inverter and eliminating a feedback loop including a transfer gate. CONSTITUTION:First and second transfer gates 2 and 3 are opened and closed oppositely with each other according to the 'L' and 'H' of a clock signal CLK, fetches an input data signal D in an FF 10 and transfers the data latched to the FF 10 as an output data signal Q. The power supply of the FF 10 is supplied via MOSFET 15 and 16 simultaneously opening and closing according to the clock signal CLK. Namely, because the FF 10 operates as a clocked inverter, setup time is short as compared with a feedback loop form including a transfer gate. While power supply is turned off, an MOSFET 17 becomes conducting, holds the potential of a node A 10 to VDD/2, for instance, and makes the FF 10 a balanced state. Thus, the rising of a circuit in the next operating period is speeded up.

Title: Electrode bump for semiconductor chip
Inventor: NAKAJIMA TAKASHI
IPC: H01L21/60
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To ensure good bondability of a semiconductor chip to a wiring board by a method, wherein an electrode bump uses a conductive resin as its constituent member, has an Ni-plated layer in its first surface layer, has an Al-plated layer in its second surface layer and is formed in such a way that the bump is formed into a curve, which is formed into a roughly gull-wing form from the point part of the bump towards the peripheral edge part of the bottom of the bump. SOLUTION: A bump 8 is aligned with an electrode pad 10 on a wiring board 9, and the bump 8 is reflowed to bond together a semiconductor chip 1 and the board 9. At this time, since a creamy solder is applied on the pad 10, the solder 11 is sucked up to approximately half the height of the bump 8 and an Au-plated layer 7 is etched, however since the layer 7 is a thin layer, the tender layer of the layer 7 is formed into a small form to the utmost and at the same time, as the solder is bonded to an Ni-plated layer 6 by an anchor effect, the solder is obtained a firm bonded state. Moreover, since the bump 8 has a curve, which is formed into a roughly gull-wing form from the point thereof towards the peripheral edge part of the bottom thereof, this curve part makes a flexible motion for buffering thermal stresses even if the bump 8 is subjected to thermal stresses.
