Title: Liquid level detector
Inventor: TANAKA KAZUHIRO
IPC: G01F23/26
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To prevent generation of defective data caused by erroneous detection of a liquid level by detecting the variation of an electric signal generated when a conductive disposable chip fitted to the tip of a suction nozzle touches the liquid surface, from that generated when it leaves the liquid surface. SOLUTION: A conductive disposable chip 111 is fitted to the tip of a suction nozzle 101, and a motor 105 is controlled by a computer 104. And a vertically moving mechanism 106 is driven to move the suction nozzle 101 vertically. If the suction nozzle 101 reaches a liquid surface, an output signal increases into a stepped shape, and the liquid-level detecting element 110 performs differentiation, and detects a stepped output signal increase when the differentiated value dV exceeds a threshold value dVth1, and the suction nozzle is stopped descending through the use of the computer 104. Next, (a differentiated value)-dV is checked at the time of an ascending start of the nozzle, and when it exceeds (a threshold value)-dVth2 the liquid level is judged to be normal. If (a differentiated value)-dV does not exceed (a threshold value)-dVth2, here, an alarm representing a noise is outputted.

Inventor: INATANI TOSHIHIRO
IPC: C21B13/00
Filed: 1982-12-21
Abstract: PURPOSE:To transfer smoothly preliminarily reduced ore while preventing the decrease in temp. and reoxidation by transferring the ore by gravity under oscillation of a transfer pipe in the first half of the transfer of said ore from a preliminary reduction furnace to a vertical furnace and by gas in the second half. CONSTITUTION:The ultrasonic wave generated in an ultrasonic generator 14 is converted by an oscillator 15 to a mechanical oscillation which is transmitted, via an oscillation transmission body 8, to a transfer pipe 6. The preliminarily reduced ore from a preliminary fluidized reduction furnace 2 is transferred by gravity under oscillation of the pipe 6 in the above-mentioned way, whereby the clogging in the pipe 6 owing to welding between high temp. powder and the inside surface of the pipe or sintering and stagnating of the powder is thoroughly prevented. The ore is then pneumatically transferred by the carrier gas blown from a blow port 7 provided the midway of the pipe 6 and in succession the ore is entrained in the preheating air flow from a tuyere branch 12 branched from a blast main pipe 16 and is thereby blown into a vertical furnace 3.

Inventor: KAN SEKIKAN
IPC: F24H1/00
Filed: 1990-08-24
Abstract: PURPOSE: To achieve a miniaturization of the apparatus while improving heat efficiency, by arranging a circulation circuit in which cold water passes through a heat exchanger of a gas burner via a pump and a hot water heat exchanger to be turned to hot water, while a solenoid valve is installed between an inlet pipe and an outlet pipe having a water flow sensor to perform a mutual heat exchange between the hot water and heating water. CONSTITUTION: Heating water circulated by a heating water pump 4 undergoes a heat exchange within a heat exchanger 6 of a gas burner 5 and delivered to perform a heating function sequentially. At the same time, cold water supplied through a hot water circuit undergoes a heat exchange while being fed to the heat exchanger 6 of the gas burner 5 by the pump 4 and delivered as hot water through an outlet pipe 12. At this point, when the hot water is not used, as a valve linked to the side of the outlet pipe 12 of the hot water is tightened, the tightening is checked by a water stream sensor 11 to release a solenoid valve 13 linked thereto. The hot water pumped by a pump 8 while the hot water circuit forms a close circuit is recirculated to undergo heat exchange with the heating water in a hot water heat exchanger tube 3.

Title: Gum platen roller
Inventor: SAWANO MITSURU
IPC: B65H27/00
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent the relative positional deviation between a recording material and a platen from developing and contrive to reduce a registrational deviation by a method wherein a gum platen roller has a tacky layer at its outer peripheral surface so as to transfer the recording material through pivoting under the state being stuck to the surface opposite to the image receiving surface of the recording material by means of the adhesion of the tacky layer. SOLUTION: A recording sheet 13 is transferred by the distance, which is always equivalent to the peripheral moving distance of a rotating gum platen roller 21, by rotating the gum platen roller 21 closely contacting with the rear surface of the recording sheet 13 by means of proper adhesion as the printing of images. Since a tacky layer 25 is formed at the outer periphery of the gum platen roller so as to adhere to the rear surface of the recording sheet 13 by means of some degree of tackiness, no relative positional deviation between the recording sheet 13 and the gum platen roller 21 develops at the printing of color images and the registrational deviation among respective colors can be prevented from occurring. As a result, the quality of an especially high fine color image can be improved.

Title: Stator blade of axial-flow turbo machine
Inventor: KANO YOSHIO
IPC: F01D9/02
Filed: 1993-09-09
Abstract: PURPOSE:To reduce loss due to the secondary flow vortex which tends to be generated in an inter-blade flow changing the inclination angle in the axial direction of a stator blade to a radius direction, and forming a shape on a meridian plane in that of a bow, protruding in a direction of the leading edge of the stator blade. CONSTITUTION:The radial distribution of the axial inclination angle delta of a stator blade 3 is so arranged that it may be a bow shape, protruding toward a leading edge 4. The axial inclination angle delta means angle formed by the tangential line of the leading edge of the blade and a line which runs through the leading edge and is perpendicular to a rotary shaft. A blade surface from the curved part of the stator blade to the downstream side serves as a flow passage which permits a flow to be pressed toward a side wall, thereby an inter-blade flow which restrains a boundary layer generated in on side wall or the secondary flow vortex that is generated in an inter-blade passage. With the bow shape protruding toward the leading edge of the blade, it is possible to prevent a flowing-out angle from being largely affected, and reduce the development of the secondary flow vortex which is generated in the side wall boundary layer end/or the inter-blade flow passage, thereby the loss distribution of a flow which occurs on the stator blade is reduced.

Title: Fineness measuring instrument
Inventor: ITO AKIRA
IPC: G01N19/00
Filed: 1988-09-07
Abstract: PURPOSE:To measure the fineness of a thread being in course of reeling by applying a load to a sensor to turn the sensor against the frictional resistance of the thread running in the gap of the sensor and taking the number of driving pulses corresponding to the load value at this time as the function to detect the fineness of the thread. CONSTITUTION:Before the start of a cycle, a sensor 2 is turned downward by its own weight and the thread is placed in a position 14. When the cycle is started, an intermittent lever 9 is moved forward, and a hourglass wheel 10 is turned, and the thread reaches a position 13 and is inserted to a sensor gap 15, and the sensor 2 is turned upward by the friction of the thread. The operation is started while counting pulses from 0 to a set pulse number in this state, and a pulse motor 8 is rotated, and a chain 6 pushes up a load receiving part 5 through a load lever 11 to apply the load to the sensor 2 downward. When application of the load is continued, the balance between the frictional resistance of the thread and the load is lost and the sensor 2 is turned downward. At this time, the motor 8 is stopped and the number of pulses is recorded. This number of pulses is calculated to obtain data of the fineness, and it is processed by a computer to perform fineness management.
