Title: Combusting equipment for liquid fuel
Inventor: UNO JIYOUJI
IPC: F23N1/02
Filed: 1979-12-28
Abstract: PURPOSE: To make the concentration of the premixed gas thicker at the igniting time than that in the time of burning and facilitate ignition, by a simple method of applying pressure to the pressure pipe later than the constant oil lever reservoir.  
     CONSTITUTION: With a fan 1 starting to turn in response to the igniting signal, the oil level of a pressure pipe 14 rises up to the C-C line which is by h 0  higher than the B-B line, where "h 0 " is the value of the static pressure P 1  exprssed in terms of  the oil column. At the same time, the oil level of the slender pipe 19 rises to the  position where the level is by ε higher than the C-C line. Some time is required  for the oil level to reach the above-mentioned position because the oil of the constant oil level reservoir 8 is throttled by the orifice 17. Next, the switching valve 16  is actuated, the connecting pipe Z is interconnected with the pipe W, and a static  pressure P 1  of the air is applied to the oil level of the pressure pipe 14. In order that  the static pressure P 1  is newly added to the oil between the orifices 17 and 18, the  oil level of the slender pipe 19 at the side of flow F of the orifice 18 is pushed up to  above the highest point 19b and reaches the fuel feed outlet 19a, where the oil is  atomized by the surrounding air stream of high velocity and flows into the vaporizing chamber 5.

IPC: H04R3/00
Filed: 1987-07-10
Abstract: PURPOSE:To block a noise or an impact noise and to maintain the audibility of a speech voice by providing a filter to extract the speech voice frequency band component, and providing a level limitation circuit to limit the level of an output signal from a microphone amplifier. CONSTITUTION:An electrical signal outputted from the microphone MK is amplified in the microphone amplifier MA, then inputted to the filter FL. The filter FL passes only the speech voice in the pass band of 600-1500Hz, but blocks other frequencies, i.e., noises. A speech voice passed through the filter FL is amplified by a headphone amplifier HA, then supplied to two speakers SP1, SP2, and the speech voice is emitted as a physical voice onto the left and right ear pads of an earmuff. Meanwhile, the output signal level of the amplifier MA is detected by the level limitation circuit LM, and corresponding to the high and low of the output level, the input level of the amplifier MA is varied high and low. Therefore, an impact noise that exceeds a prescribed level can be blocked.

Filed: 1985-08-07
Abstract: PURPOSE:To improve stability to vibration, etc., by forming convex surfaces as respective mirror surfaces of a polygon mirror formed by sticking plural mirror surfaces polygonally and setting the radius of curvature of each mirror surface larger than the radius of rotation of the side edge part of each mirror surface. CONSTITUTION:Each mirror surface 12 is formed convexly along the center axis of a mirror body 11 and the radius R of curvature is set larger than the radius (r) of rotation of the side edge part 12 of each mirror surface 12. A laser oscillator 14 for scanning the inspected surface 13a of an object body 13 by utilizing laser light is installed beside the polygon mirror 10.

Title: Ruthenium volatilization suppression method
Inventor: HOSHIKAWA TADAHIRO
IPC: G21F9/06
Filed: 1993-07-14
Abstract: PURPOSE:To eliminate ruthenium without increasing the number of steps by storing evaporation-processed liquid waste in a reservoir tank, decomposing volatile ruthenium into non-volatile form and suppressing the volatilization of ruthenium. CONSTITUTION:When liquid waste containing ruthenium is evaporation-processed in a radioactive liquid waste evaporator 1, ruthenium changes to have a volitile form and is contained in the condensed solution in a condenser. This solution is temporarily stored in a reservoir tank 2 before being processed in the later step evaporator. If, at this moment, the oxygen concentration in the solution in the reservoir tank 2 is 0.002 normal or less, it is stored for 5 hours or more and then the volatile ruthenium is decomposed into a non-volatile form. It changes in the solution to an insoluble form to be separated out of the solution and this is filtered 3 to be removed. In this process, ruthenium concentration in the liquid waste decreases and so the ruthenium in the liquid waste can be removed by an evaporation process. Therefore, radiation confinement ratio can be improved without increasing secondary radioactive waste.

IPC: A61B3/10
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To perform highly accurate detection by simplifying the structure of an optical system and keeping constant the expansion of a received luminous flux irrespective of visibility. SOLUTION: A focus is adjusted by driving a movable part 20 toward optical paths 01 and 02, and an image sensor 7, a distant view mark 14 and a diaphragm 16 are conjugated in an eyeground of an eye E to be inspected. A dotted luminous flux is projected to the eyeground, an eyeground reflected light is separated into 6 luminous fluxes and deflected by a luminous flux separation deflecting member 4, and received by the image sensor 7 as 6 luminous fluxes L. Since the luminous flux separation deflecting member 4 is located in the focusing position of a lens 6, when the image sensor 7 is conjugated with the eyeground, the expansion of 6 luminous fluxes L on the image sensor 7 is kept constant irrespective of the visibility of the eye E.  The signal of the image sensor 7 in focus is taken in by a not-shown computing means, the positions of 6 luminous fluxes L are computed, and a refraction value containing the random view of the eye E to be inspected is computed from the position of the image sensor 7 in the direction of the optical path 01 obtained from the position of the movable part 20 at this time and the positions of 6 luminous fluxes in the surface of the image sensor 7.

Title: Double feed sensing device
Inventor: WATANABE KOUICHI
IPC: H04N1/00
Filed: 1982-10-06
Abstract: PURPOSE:To have sensing of double feed, which can be performed independently from the format of sheets used, by furnishing air intake holes at the two opposite positions of a sheet guide of a facsimile read device and by allowing either of them to attract one sheet, if the case is such, and both intake holes to attract two or more sheets through the action of pressure difference in the sutction negative pressure. CONSTITUTION:If two or more sheets of original text 22 are sent out, the negative pressure P1 at a main air intake 32 is larger than the negative pressure P2 at an aux. air intake 37, so that the under lying sheet 22 is attracted by the main air intake 32 while the upper lying sheet 22 runs being attracted by the aux. air intake 37. That is, the under lying sheet runs along the lower plate of sheet guide 24 while the over lying sheet along the upper plate of the guide 24. Accordingly the distance L2 between a reflex type photosensor 43 and the over lying sheet is compartively small, and the amount of light corresponding to this distance is received by the photosensor 43, in which the amount of light received is larger than the reference light amount, so that the control circuit judges that two or more sheets of original text 22 have been sent off. According to this arrangement, in which the sensing is made not on the basis of difference in penetrating light amount, double feed can be surely sensed even when semitransparent or transparent sheets are used.
