Coupling capacitors are connected between an input end and an output end, a resonator is connected between each of the coupling capacitor and the ground, and a capacitor and a switch are connected between one end of each resonator and the ground. When the capacitor is off, the frequency is set to the resonance frequency of the resonator, and when the switch is turned on, the capacitor is connected parallel to the resonator, so that the resonance frequency is shifted to a lower value, whereby a dielectric filter having multiple frequencies can be obtained.

In an address multiplexing apparatus for multiplexing address data to be supplied to 64K bit, 256K bit, and 1M bit DRAMs, upon multiplexing of address data, input address data of 20 bits are classified into two groups, i.e., the lower 16 bits and the upper 4 bits. The lower 16-bit group is multiplexed so that the upper 8 bits serve as row address data, and the remaining lower 8 bits serve as column address data. In the upper 4-bit group, adjacent bits are multiplexed. The apparatus can be commonly used for the three memories having different capacities with the simple circuit arrangement, and page mode access can be executed.

Substituted benzylcycloalkenylurea derivatives of the formula (I) ##STR1## wherein X represents a halogen atom or a lower alkyl group, Y represents an oxygen atom or a sulfur atom,R.sup.1 represents a cycloalkenyl group andR.sup.2 represents a lower alkyl group, a cycloalkyl group, a benzyl group or a phenyl group optionally substituted by 1 to 5 substituents selected from the group consisting of a hydroxyl group or a lower alkoxy groupand their use as fungicides. They can be synthesized, for example, by reacting of a substituted benzyl-cycloalkenylamine with an isocyanate or by reacting of a carbamoyl halide with an amine. The starting material, the substituted benzyl-cycloalkenyl amines, are also new.

An information processing apparatus is provided in which a processor is connected to a memory via address and data buses and an address bus is connected via a continuous address-specifying signal generating circuit. In a continuous access mode, the continuous address data generating circuit is responsive to an instruction signal for re-setting itself to an initial value and sequentially supplying a continuous address data to the memory's designated address. In the continuous access mode, the address bus is employed, together with the aforementioned data bus, as a data bus in a parallel fashion so that a data transfer capability can be extended.
摘要:
A hook or male element for surface fasteners which is made of a thermoplastic monofilamentary material and which is provided with a coarse surface finish having a multiplicity of alternate minute recesses and ridges, giving rise in its frictional force and ensuring firm, stable engagement with loop or female elements. Having the minute recesses throughout its surface, this hook element can be dyed homogeneously or distinctly at the user's request.

A piezoelectric fan includes a tuning-fork type vibrator having two sides. A first piezoelectric element is formed on each of the two sides of the vibrator. Further, an exciting electrode is formed on each of these first piezoelectric elements. Also, a feedback electrode is formed on one of the first piezoelectric elements an electrically insulated from the exciting electrode. Furthermore, a blade is attached to the tip of each of the two sides of the vibrator. Then, this piezoelectric fan is driven in a self-exciting fashion by feeding an output from the feedback electrode to the exciting electrode. Also, in this piezoelectric fan, a vibrational node is formed at nearly the middle point of the vibrator at free vibration.
摘要:
A three-color separation electrophotographic color reproduction process which includes primary uniform charge steps, color separation image exposure steps, development steps and transfer steps. The process further includes between each image exposure step and development step a uniform exposure step and a secondary charge step. The secondary charge step is carried out either by DC corona discharge of the same plurality as the primary charge step or by AC corona discharge together with DC corona discharge. The quantity of light of the uniform exposure step and the quantity of charge of the secondary charge step are controlled, to reduce stepwise, as the second and third primary color reproduction proceeds.
摘要:
In the method and apparatus for controlling electronically the fuel injection in an internal combustion engine, an interruption routine of the main routine is performed. In the interruption routine, the control logic is selected in accordance with the value of the calculated basic width of the pulse for the fuel injection. The degree of increase or decrease of the amount of the fuel injection is regulated based on the selected control logic.
