IPC: H03K19/0948
Filed: 1981-09-18
Abstract: PURPOSE:To obtain a complementary logical circuit in high speed, by using a ratio circuit constituting a driving circuit with an N-channel MOSFET in common with a CMOS circuit and taking a current mirror circuit consisting of a P-channel MOSFET as a load circuit. CONSTITUTION:A source of a P-MOSFETP1 is connected to a power supply terminal 5 and a gate and a drain are connected to a connecting point 6. N- MOSFETs N1, N2 are connected to the connecting point 6 via resistors R1, R2. An inverter circuit is constituted by using P-MOSFETs P2, P3 and N-MOSFETs N3, N4 and the gate of the FETs P2, P3 is connected to the connecting point 6. Thus, when a potential at an input terminal 11 changes from a high to a low level, since the potential at a connecting point 7 changes from a low to a high level, a current flowing to the FETP2 is made almost constant. Thus, the dispersion in a reference current of a current mirror circuit can be avoided and the operation of the circuit can be made high in speed.

Title: Silver halide color photographic sensitive material
Inventor: KUMASHIRO KENJI
IPC: G03C7/26
Filed: 1985-07-04
Abstract: PURPOSE:To obtain a silver halide photosensitive material having improved sharpness and granular characteristic by specifying the silver density of green sensitive layers constituted of 1 or >=2 layers at >=5.0X10<-1>g/cm<3> and the total of the dry film thickness of the green sensitive layers at <=4.5mum. CONSTITUTION:The green density of the green sensitive layers constituted of 1 or >=2 layers is >=5.0X10<-1>g/cm<3> and the total of the dry film thickness of the green sensitive layers is <=4.5mum. The green density provides the tendency to the deterioration of the granular characteristic and an increase of fogging if said density is made excessively high; therefore, the more preferable range is >=7.0X10<-1>g/cm<3> and <=2.0g/cm<3>. The deteriorated coatability, pressure characteristic and stability of emulsified matter and the generation of a side effect such as a decrease of the coloring density are resulted if the dry film thickness of the entire green sensitive layer is made excessively small; therefore, the more preferable range of the dry film thickness is >=1.0mum and <=4.0mum. The green sensitive layers preferably contain the magenta dye image forming coupler expressed by the formula in at least one layer of the green sensitive layers and more preferably contain the coupler in all of the green sensitive layers.
