摘要:
On a semiconductor chip, ends of a plurality of resistive elements of a pull-up resistor unit disposed in parallel to each other are connected to a power source, other ends of the resistive elements are connected to a line connecting a signal input terminal and a receiving end device disposed on the semiconductor chip, and the line is connected to the ground through an external resistor disposed on the outside of the semiconductor chip. A current flows from the power source to the ground, and a node voltage depending on a resistance value of the external resistor and a composite resistance of the pull-up resistor unit is applied to a node between the line and the external resistor. The composite resistance of the pull-up resistor unit functioning as a termination resistor is corrected to an expected value according to the node voltage.

A smoking aid for reducing concentrations of poisonous substances contained in tobacco smoke including a pipe bowl having a smoke retaining cavity, a stem coupled with the pipe bowl and a mouthpiece connected to the stem. A cap-like member is movably secured to a top portion of the pipe bowl such that a space formed between the pipe bowl and cap-like member can be adjusted. A hole is formed in a top wall of the cap-like member, through said hole a root portion of a cigarette may be protruded into the smoke retaining cavity. By moving the cap-like member relative to the pipe bowl to adjust a dimension of the space, it is possible to adjust an amount of clean air introduced into the smoke retaining cavity to control a dilution of tobacco smoke.

A synchronous clock phase control circuit includes a T/8 step phase clock generation unit, a phase selection unit, and four synchronous clock generation units. The T/8 step phase clock generation unit generates eight clocks previously delayed in phase by T/8 from an input clock. The phase selection unit selects four control clocks from the eight clocks generated by the phase clock generation unit based on four phase control signals, respectively. The four synchronous clock generation units synchronize the selected clocks with an externally input trigger signal TR using the input clock as a reference, and output the selected clocks when synchronization is established, respectively.

A process for the preparation of microcapsules having a wall membrane made of a polyurethane urea resin, which includes steps of mixing an oily solution and an aqueous solution, passing the resulting mixed solution through a clearance between an inner cylinder and an outer cylinder which are rotated relative to each other to form an oil-in-water type emulsion, and then forming a wall membrane on droplets of the resulting emulsion. In a preferred embodiment, the clearance between the inner cylinder and the outer cylinder is preferably in the range of 0.05 to 5 mm, more preferably 0.1 to 2 mm. The retention time of the emulsion in the clearance portion is in the range of 0.02 seconds or more, preferably 0.2 seconds or more. The inner and outer cylinders are in the form of column, optionally conical in part thereof.

A light-sensitive microcapsule contains silver halide, a reducing agent, an ethylenically unsaturated polymerizable compound and a color image forming substance. Another light-sensitive microcapsule contains a photopolymerization initiator, an ethylenically unsaturated polymerizable compound and a color image forming substance. The microcapsules are prepared by a process comprising the steps of emulsifying an oily phase containing the silver halide, the reducing agent, the polymerizable compound and the color image forming substance (or an oily phase containing the photopolymerization initiator, the polymerizable compound and the color image forming substance) in an aqueous medium containing a water-soluble polymer in water; and forming the shell around the droplets of the oily phase. In the process of the present invention, the oily phase is emulsified in the aqueous medium by mixing the oily phase and the aqueous medium; supplying the mixture to a clearance of not larger than 5 mm between an inner cylinder and an outer cylinder; passing the mixture through the clearance while rotating the outer cylinder and/or the inner cylinder. Light-sensitive materials prepared by using the light-sensitive microcapsules are also disclosed.
