Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To improve the solderability by compounding a metal which is easily alloyed with solder, a metal difficult to diffuse in solder, an oxide for blocking solder from entering, and a resin at a specified wt.%. SOLUTION: A conductive compsn. comprises a metal which is easily alloyed with solder 28-45 wt.%, a metal which hardly diffuses in solder 25-60 wt.%, and an oxide 3-7 wt.%. If the components exceed the upper or lower limit, the solder wettability of the compsn. will be deteriorated or solder will penetrate too deep into the compsn. The resin content of the compsn. is set to 7-30 wt.%. If it is less, the adhesion to the solder will lower, and if it exceeds, the conductivity will decrease.

Abstract: PURPOSE:To obtain a semiconductor integrated device operating at high speed with low layout area by providing the serial circuit of an MOS transistor to switch the corrector current value of a first bipolar transistor and the emitter current value of a second bipolar transistor. CONSTITUTION:When one of the serial circuits among those from a first through an N-th PMOSTr in a current switching circuit SWP is energized, a bipolar TrQ1 is ON and a current mirror connected Q0 is ON. When the sum of the ON resistance of the Q0 and the ON resistance of a current switching circuit SWN is set sufficiently smaller than a Z1, the Q0 is ON and then, an output D0 is pulled down approximately to a VSS electric potential. Reversely, when any of the serial circuits of a first MOSTr is not conducted, regardless of whether the circuit SWP is ON or OFF, TrQ0 and Q1 are OFF. Then, the output D0 is pulled up to a VDD electric potential by a load circuit Z. Then, the conducting and non-conducting of the SWP can be controlled by the 1.5V input signal in the same way as the SWN.

Title: Pll circuit
Inventor: SAKATA TSUGUHIDE
IPC: H03L7/089
Filed: 1983-10-14
Abstract: PURPOSE:To attain high speed response and also to realize high stability by decreasing substantially the period controlling the oscillation of a voltage controlled oscillator (VCO) in a loop so as to reduce a dead time of the loop. CONSTITUTION:An external input rectangular wave signal (a) is impressed to a monostable multivibrator MM13 from a terminal 5 and the MM13 applies a pulse (b) having a pulse width TW to a phase comparator PD12. When an output of the MM13 is at high level, the PD12 outputs a high level VH or a low level VL, and when the output of the MM13 is at low level, the PD12 outputs an intermediate level VM. When the output of a frequency divider 4 is at high level, the PD12 outputs the VL at the period of the TW and the PD12 outputs the VH at the low level. If there is a difference between the phase of the output signal of the frequency divider 4 and the phase of an externally inputted rectangular wave signal, the ratio of a period TH when the PD12 outputs the VH to a period TL when the PD12 outputs the VL is changed in the TW and the phase of the output signal of the frequency divider 4 is controlled so that the phase difference is made coincident. The output of the PD12 is the VM at the period other than the TW, and the VCO3 is brought substantially into the free running state.

Title: Toner for developing electrostatic charge image
Inventor: IWAMOTO YASUTAKA
IPC: G03G9/09
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To obtain excellent chargeability by incorporating or adding carbon black within a specified range to toner and to prevent the surface staining of an image in the case of developing an electrostatic image by using such toner. SOLUTION: The carbon black whose volatile component per unit specific surface area (wt.%/(m<2> /g) is within 0.8 to 5.0 is incorporated or added to the toner. When the volatile component per unit surface area is within 0.8 to 5.0 (wt.%/(m<2> /g)), the dispersibility of the carbon black is improved. The volatile component of the carbon black is a value showing the existence amount of CO, CO2 and H2 components combined on the surface, and the existence of the components per unit area is a point in the case of improving the dispersibility of the carbon black in the toner. Since the components are largely related to wettability with the binder resin, the wettability is enhanced more as the components exist more, and compatibility is improved. When too many volatile components exist per unit surface area the electrified amount of the toner is lowered, so that it is necessary to set the volatile component to an appropriate value.
