    摘要: A process for forming a functional ceramic thin film eliminating the need of high temperature annealing which has been indispensable in the conventional process is provided. This can be achieved by the process for forming a functional ceramic thin film having a crystal of a composite oxide consisting of two or more metal elements and oxygen, which comprises steps of alternately stacking seeding layers having the same crystalline structure as said composite oxide and formable at a temperature lower than the crystallization temperature of the composite oxide, and layers containing a larger amount of a specified metal element than said seeding layers, and then annealing the resultant layers to form an integral body.

    摘要: In an internal combustion engine, on a cylinder head side, a tumble flow is formed that is directed from an intake vent opened on the cylinder head to an exhaust vent opened on the cylinder head. A direct injection valve injects fuel directly into a combustion space. The direct injection valve injects the fuel toward a section where a piston top surface intersects with a cylinder inner surface, at a point closer to an intake top dead center than a middle between the intake top dead center and an intake bottom dead center, and thereafter injects the fuel into the combustion space again.

    摘要: A digital-analog converter including a first selection circuit of switch elements, which are coupled to each other and to a high potential power supply, and a second selection circuit of switch elements, which are coupled to each other and to a low potential power supply. First and second voltage dividing circuit each include series-connected resistor elements, each coupled between adjacent switch elements of the corresponding selection circuit. A control circuit provides a control signal to the selection circuits to activate one of the switch elements in each selection circuit and couple the activated switch element to the corresponding potential power supply. The first and second voltage dividing circuits divide voltages of the high and low potential power supplies with the resistor elements between the activated switch elements.

    摘要: It is intended to provide an A/D converter circuit with which, by using a clock signal, on the basis of an analog voltage inputted a predetermined time past, it is possible to select suitably comparators to be operated and comparators to be rested, and which has small consumed power. A parallel-type A/D-converter circuit 200 converts an analog voltage VIN to a digital value DOUT at intervals of a predetermined period by means of a clock signal CLK using chopper-type comparators 1-7. The comparators 1-7 can each be set by first and second setting signals CONT1A etc. to either of an operating state and a resting state. A comparator control circuit section 211 performs logical processing on the comparator outputs OUT1-OUT7 in the preceding conversion to generate the first and second setting signals CONT1A etc., and brings some of the comparators to the operating state and holds the remaining comparators in the resting state.
