Title: Dust trap device of combustion device
Inventor: EDA AKITO
IPC: F23D14/68
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To surely trap and remove the dust in the air flow to be introduced into an air volume detection sensor. SOLUTION: A part of the combustion air is introduced from an inlet side 43 to a dust trap passage 37. First U-turn walls 41a and second U-turn walls 41b are provided in an array on one side of a passage side wall of the dust trap passage 37 and on a passage side wall opposite thereto, respectively. The flow of the air passing through the dust trap passage 37 is converted into the U-turn flow in the opposite direction by the first U-turn walls 41a, and again converted into the U-turn flow by the second U-turn walls 41b, and the air flow is thus passed in a meandering manner. When the air flow is U-turned, the dust contained in the air is removed from the route of the air flow by its inertia force, and collided with the first U-turn walls 41a and the second U-turn walls 41b to be trapped and removed.  The air free from any dust is introduced to an air volume detection sensor 16 to prevent the dust from being adhered to the air volume sensor 16.

Inventor: MIYAIRI NOBUO
IPC: G11B7/00
Filed: 1990-11-22
Abstract: PURPOSE:To prevent the deterioration of an MTF by composing the title conversion circuit of a photoelectric conversion means receiving returned light from an optical recording medium and capable of photoelectrically converting returned light and an amplifying means converting currents obtained from the photoelectric conversion means into voltage and having a feedback resistor determining gains and constituting the feedback resistor of at least a plurality of resistors connected in series. CONSTITUTION:An amplifier 3 composed of a detector 2 capable of photoelectrically converting light from an optical recording medium and an amplifier 3 converting photocurrent formed from the detector 2 into voltage is fed back through a feedback resistor 8, in which a resistor 5 having a capacitor 4 as a component and a resistor 7 having a capacitor 6 as a component are connected in series. Photocurrents formed by the detector 2 are converted into voltage by the amplifier 3 and the feedback resistor 8 at that time. Since the resistors 5 and 7 are connected in series, the value of combined resistance is doubled, and the value of combined capacitor is halved. Accordingly, the deterioration of an MTF defined by formula I can be prevented by simply reducing a capacitor component and without changing a resistance value.

Abstract: PURPOSE:To prevent fine particles from remaining in the vicinity of a Brewster window by providing a purge air press-charging hole in a position corresponding to an external mirror on a detecting cell enclosure, and providing a purge air discharging hole in a position corresponding to the Brewster window on this enclosure. CONSTITUTION:Purge air P is press-injected and sprayed from a press-charging hole 151 provided in the position corresponding to an external mirror 133 on an enclosure 11 of a detecting cell 1 to clean the mirror 133 and its periphery, and thereafter, purge air P passes the periphery of a detection area S to clean a Brewster window 132 and its periphery 132 and is discharged to the outside through a discharging hole 152'. In this case, the speed of running purge air P is made sufficiently lower than that of running air A to be checked, and thereby, purge air P passes the periphery of air A to be checked and does not join this air A. Thus, remaining fine particles are prevented from penetrating the detection area by cleaning or the like of the Brewster window 132, and the measurement error does not occur to improve the reliability.

Title: Stereoscopic electrophoresis type display element
Inventor: NAKAMURA NAOKI
IPC: G02F1/167
Filed: 1988-12-20
Abstract: PURPOSE:To enable multicolor stereoscopic display by forming in relief the stereoscopic display patterns of the color of dispersion particles in the color of the dispersion medium which is a background color by application of a voltage. CONSTITUTION:The dispersion particles 4 are held dispersed in the dispersion medium 5 in the case of not impressing the voltage to electrode layers 2a, 2b and, therefore, the color of the dye of the dispersion medium which is the background color is displayed on a display side transparent substrate 1b. If the voltage is applied in such a manner that the polarities of the dispersion particles 4 and the electrode layer on the rear side substrate 1a are reversed, the dispersion particles 4 stick to the electrode layer 2a on the rear side substrate 1a and, therefore, the color of the dye of the dispersion medium which is the background color is displayed on the display side transparent substrate 1b. If the voltage is so applied as to reverse the polarity of the electrification of the dispersion particles 4 and the polarity of the electrode layer of the display side transparent substrate, the dispersion particles 4 migrate in the dispersion medium 5 and stick to the electrode 2b on the display side transparent substrate 1b. The electrodes are then stereoscopically displayed in the color of the dispersion particles in the shape of characters or figures. The multicolor and high-contrast stereoscopic display is enabled in this way.

Title: Polarization modulator and optical fiber gyro
Inventor: NISHIURA YOZO
IPC: G01C19/72
Filed: 1992-11-04
Abstract: PURPOSE:To timely vary the difference of refractive index between two lights having polarization faces in a radius direction and a right-angle direction against it by winding a single-mode optical fiber around a cylindrical or columnar piezoelectric element having electrodes a plurality of times while applying tension, and applying AC voltage between the electrodes. CONSTITUTION:When a single-mode optical fiber is wound on the outer circumference of a piezoelectric element while applying any tension, the upper and lower fibers forms an uneven surface due to partly double winding and ununiform winding direction, resulting in generating kinking in the upper-layer fiber. A piezoelectric vibrator will vibrate when its electrode is applied with AC voltage, and the fiber will be expanded/compressed simultaneously, thereby varying an optical path length. Through such a winding, the stress is concentrated, the birefringence of fiber is increased, the AC voltage is applied between the electrodes, and the polarization face is modulated as a result. In addition, the titled modulator is put into between the light source of an optical fiber gyro and a polarizer or the polarizer and a fiber coil, so that it can be substituted for a depolarizer.
