A particle detector includes a light source, and a metal layer having an incident/reflective surface and a photoelectric surface opposing the incident/reflective surface. Incident light from the light source reaches the incident/reflective surface to excite near-field surface plasmon resonance photons at the photoelectric surface. A particle deposited on the photoelectric surface of the metal layer changes the near-field surface plasmon resonance photons to far-field scattered light. The particle detector further includes a scattered light detecting unit, provided above the photoelectric surface of the metal layer, for detecting the far-field scattered light.

A dilution monitoring system for filter cigarettes has pairs of pressure sensors provided individually for left- and right-hand manufactured filter cigarettes, a dilution processor card adapted to receive pressure signals from the pressure sensors through an A/D converter, and a server computer connected to the processor card by means of a communication line and including a CRT. The dilution processor card computes the respective dilutions of the individual filter cigarettes in accordance with the pressure signals, and stores the computation results in a RAM. Thereafter, the processor card obtains quality data, such as the average, frequency distribution, and standard deviation of the stored dilutions, for each group of the left- and right-hand filter cigarettes, also stores the quality data in the RAM. The server computer receives the quality data transmitted from the processor card, and displays them in the form of a graph or table on the CRT.

A printer for a cigarette-manufacturing machine has a density sensor (70) disposed between a wrapping section (4) and a cutting section (16) of the machine, and the density sensor (70) detects the print density of printed information (PI) of a tobacco rod (TR). The information (PI) is printed on a paper web W by a printing unit (20) located upstream from the wrapping section (4). Disposed between the printing unit (20) and the wrapping section (4) is an adjusting device (62) for varying the length of a feeding path of the paper web W. A density signal from the density sensor (70) is used to control the operation of the printing unit (20) and adjusting device (62). Thus, based on the density signal, the print density of the printed information (PI) and the arrival timing thereof at the density sensor (70) are each controlled.

摘要:
A compact millimeter wave radar transceiver at low cost is provided wherein a direct current voltage applying circuit is coupled to a high frequency line to apply a fast pulse wave without losing a sharp input pulse pattern. A voltage is applied to a negative resistance diode, such as a Gunn diode, which is variably controlled to vary the diode oscillating frequency signal, which signal is outputted as a transmitting wave. The transmitted wave is reflected by a target and received by the negative resistance diode. The received wave is detected as a heterodyne detection utilizing a non-linear property of the negative resistance diode. A frequency difference between the transmitted wave and the received reflected wave is outputted via a low-pass filter and processed to detect the target. To keep the sharp pulse wave pattern for applying to the high frequency line, a Y-shaped power distributor, “Wilkinson divider”, consisting of &lgr;/4 (&lgr; designates wave length) line elements Z1, Z2 and Z3, is between a capacitor connected to a high frequency input/output terminal and a direct current voltage input terminal to provide a leakage power suppressing effect between the latter terminals.
