A paper sheets identification apparatus to identify the monetary kinds of paper sheets and to determine whether or not they are genuine provides for a simplified and general purpose detection to be performed irrespectively of the difference in the portions of each of such sheets in which their optical characteristics are arranged. The paper sheets identification apparatus includes a light emitting element; a light receiving element disposed opposite to the light emitting element with the transport path of such sheets interposed therebetween; a plurality of reflective mirrors to conduct light emitted from the light emitting element to the light receiving element; and a guide to move at least one of the reflective mirrors to the direction crosswise to the transport direction of such sheets within a surface in parallel with the carriage surface.

A technology that increases bill discrimination precision, wherein a bill discriminating apparatus detects the thickness distribution of a bill P that is subject to discrimination, and by comparing this thickness distribution data and the reference thickness distribution data that shows the thickness distribution of an authentic note held in advance, performs discrimination processing that includes double feed detection, tape detection, and authenticity discrimination. Then, authenticity discrimination is performed on areas for which the difference between the thickness distribution data and the reference thickness data is within a specified range.

A thermostat independently controlling cooling water passages of two circuits, including a first valve body having first and second passages in constant communication. A third passage is selectively connected to those passages. Communication of the third passage is disconnected when the cooling water temperature is below a prescribed temperature, and the valve is opened when the cooling water temperature is equal to or higher than the prescribed temperature. A second valve body, having fourth and fifth passages selectively in communication, closes the valve to disconnect those passages when the cooling water temperature is below the prescribed temperature, and opens the valve by operating the first valve body to link the passages when the cooling water temperature is equal to or higher than the prescribed temperature. A tubular sleeve prevents first and second control chambers, respectively including the first and second valve bodies, from communicating with each other.

Improving reducing or eliminating the effects of variation in characteristics of the resonance circuit in a resonance type displacement detection apparatus, so as to improve displacement detection accuracy. In a displacement detection system, the resonance frequency range assumable by the resonance circuitis estimated in advance, there is determined a drive frequency variation range f&#x2013;fsuch that the estimated resonance frequency range is included therein, and by means of a variable oscillator, drive frequency is repeatedly varied between the first frequency fand the second frequency f. Accordingly, where the resonance frequency of the resonance circuitis fr, when the drive frequency has changed to fr, resonance voltage Vglmay be obtained in the case of large gap G. Where the resonance frequency of the resonance circuitis fr, when the drive frequency has changed to fr, resonance voltage Vglmay be obtained in the case of large gap G.

The present disclosure concerns a thermally controlled valve, such as may be installed in the cooling water system of internal combustion engines. The thermally controlled valve eliminates thermal hunting as the temperature of the cooling water increases by restricting the initial flow of cooling water. Subsequently, additional cooling water flow is permitted as the temperature of the cooling water further increases.

A pulsating noise removal device detects a pulsating noise, controls a gate circuit for selectively permitting an audio signal to pass through in response to the detection, and removes pulsating noises from the audio signal. The device particularly includes filter circuits for extracting pulsating noises and signal components from the audio signal, respectively, and includes automatic gain control circuits responsive to respective output signals of the filter circuits to respectively control the gain of an amplifier circuit for detecting pulsating noises.

Pulsating noise removal device

A gate circuit is configured to output a received signal via a buffer amplifier, enter the output in a storage capacitor via a first switching circuit normally taking its off-position, compare the signal levels at both ends of the switching circuit and feed back the comparison result to an input terminal via a second switching circuit normally taking its on-position, and configured so that when noise components in the received signal are detected, a control signal is produced to change the first switching circuit to its on-position and the second switching circuit to its off-position.

Preceding value holding gate circuit for eliminating pulsive noises

A noise eliminating signal compensation circuit in an audio device such as a car radio is configured to produce a compensation signal having the same frequency and level as those of an entered signal for signal compensation during noise removal, so as never to degrade its signal compensation capacity during noise removal when the switching time for noise removal is relatively long with respect to the wavelength of the entered signal.
