A hierarchical signal processing apparatus includes aggregates having logic operation portions. The apparatus compares a final output signal from a logic operation portion in a final aggregate with a teaching signal, and generates an error signal by taking a signal which exists only in the teaching signal as a positive error signal, and taking a signal which exists only in said final output signal as a negative error signal. An error signal generating portion in the apparatus generates a positive error signal of a logic operating portion within a certain aggregate which supplies one or more output signals thereof to said logic operation means of another aggregate based on one or more logic operations on the excitatory weight function signal of said weight function signal, the positive error signal, the inhibitory weight function signal of said weight function signal and the negative error signal, and also generates a negative error signal of said logic operation means within said certain aggregate which supplies one or more output signals thereof to said logic operation means of said other aggregate based on one or more logic operations on the inhibitory weight function signal of said weight function signal, the positive error signal of said other aggregate, the excitatory weight function signal of said weight function signal and the negative error signal.

An image forming apparatus includes an image memory section in an image processing section for temporarily storing an image signal read from an optical system via a photoelectric transducer section, an arithmetic section for numerical computation based on data stored in the image memory section, a decision section adapted to conclude that an image forming operation should be interrupted when a variation rate E of the image signal is lower than a threshold value T read from a ROM as a result of computation by the arithmetic section, and to conclude that the image forming operation should be continued when the variation rate E is equal to or higher than the threshold value T. A section is also provided for interrupting the image forming operation in response to a command from the decision section when there is no operator's key entry to order the interruption or execution of the image forming operation within a predetermined period of time.

A PLL circuit comprising a phase comparator unit which forms a differentiation signal based upon both edges of an external signal, outputs an early pulse only during a period in which the differentiation signal is overlapped on a period from the leading edge to the trailing edge of a reference signal, and outputs a late pulse only during a period in which the differentiation signal is overlapped on a period from the trailing edge to the leading edge thereof, a charge pump unit which calculates and compares the amounts of integration of the early pulse and the late pulse, lowers the output voltage when the amount of the late pulse is larger than the amount of the early pulse and raises the output voltage when it is smaller, and a VCO which outputs a corrected reference signal of which the frequency decreases or increases accompanying the increase or decrease in the output voltage of the charge pump unit, wherein the VCO is controlled by the output voltage of the charge pump unit and by the early pulse and the late pulse, and works to raise the oscillation frequency when the late pulse is longer than the early pulse and to lower the oscillation frequency when it is shorter.
摘要:
Infrared radiation is incident on a total reflection plane of a prism and penetrates a liquid sample through a metal layer put between the total reflection plane and the liquid sample in close contact therewith whereby the infrared radiation is partially absorbed by the liquid sample. Alternatively, the liquid sample may be put between the total reflection plane and the metal layer in close contact therewith so that part of the light penetrates the sample from the prism through the total reflection plane to interact with the metal layer and then is caused to reenter into the prism whereby it is partly absorbed by the liquid sample. The metal layer is for enhancing the intensity of the electric field component of the infrared radiation. The incident angle of the infrared radiation on the total reflection plane is so set that the partially absorbed infrared radiation is total-reflected. The total-reflected infrared radiation is detected by a detector so as to obtain an absorption spectrum of the liquid sample by the infrared radiation.
