Abstract: PROBLEM TO BE SOLVED: To elongate the life and also, materialize a stable ball form, by forming an opening at a discharge electrode for a bonder, and providing a plurality of projections around the inside periphery of this opening. SOLUTION: A discharge electrode 10 has an opening 11, and it is provided with a plurality of projections 13a-13f obliquely upward and besides at regular intervals around the opening 11. Discharge sections 14a-14f are made on the same circumference at the tips of the projections 13. A preliminary discharge electrode is arranged above the projection 13 to perform the preliminary discharge, and high voltage is applied between the discharge electrode 10 and the preliminary discharge electrode so as to make them perform discharge. Since this device has a plurality of projections 13, at the time of ball formation, the discharge is performed from the projection closest to the curved tail of a wire, and this device never discharges electricity from only the specified projection 13, so the abrasion occurring by the discharge decreases relatively, so the position of the discharge becomes stable. Hereby, the life can be elongated, and also this can form a ball in stable form.

Title: Internal voltage dropping circuit
Inventor: AIZAKI AKANE
IPC: H01L27/10
Filed: 1990-04-27
Abstract: PURPOSE:To improve the stand-by current characteristic of a memory by providing an external supply power potential detecting circuit to inactivate all internal voltage dropping circuits in the case of an external voltage lower than a reference voltage. CONSTITUTION:The external supply voltage is supplied to an external supply potential detecting circuit 10, a first internal supply voltage generating circuit 11, and a second internal supply voltage generating circuit 12. When the external supply voltage is lower than the reference voltage, a P-channel MOS transistor Q10 is turned off, and the potential of N10 goes to the low level. Consequently, a NOR logical output PCUT goes to the high level because having the opposite phase of N10, and an antiphase signal the inverse of PCUT goes to the low level because having the same phase as N10. That is, circuits 11 and 12 are activated/inactivated for each operation mode and external supply potential by the circuit 10. Consequently, unnecessary current consumption of internal voltage dropping circuits is suppressed. Thus, an influence upon the current consumption characteristic of the memory is reduced even in the stand-by state.

Title: Picture input device
Inventor: HATAE HIROSHI
IPC: H04N5/361
Filed: 1993-05-14
Abstract: PURPOSE:To compensate the dispersion of gain by logarithmically transforming a picture signal inputted from an amplifying means, inputting the converted signal to a subtracting means, also inputting a corresponding compensation coefficient for the amplifier means to the subtracting means and subtracting the compensation coefficient from the picture signal. CONSTITUTION:Picture input signals from respective output amplifiers are inputted to an A/D conversion means 22 while synchronizing them with respective signal output clocks. When a signal D1 outputted from the 1st amplifier means e.g. is inputted to the means 22, the signal is delayed only by time to be required for A/D conversion and the delayed signal is outputted from the means 22. When an output signal from the means 22 is inputted to a logarithmic conversion means 14, the signal is delayed only by time to be required for logarithmic transformation, the delayed signal is inputted to the subtracting means 16, a compensation coefficient logC1 corresponding to the signal D1 is outputted from a compensation coefficient storing means 20 and also inputted to the means 16. Thus the logarithmic log (D1/C1) of a compensated result is outputted from the means 16, a compensated result D1/C1 is obtained by a reverse logarithmic transformation means 18 and stored in the means 20 as a compensation coefficient.
