Title: Method for loading raw fuel such as dust block ore, self-reducing ore block, iron slug and solid fuel or the like into vertical furnace
Inventor: NAITO MASAAKI
IPC: F27B1/20
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To avoid a shelf hanging state without reducing a combustion efficiency of solid fuel with a small degree of particle size and further to enable a superior efficient operation to be carried out by a method wherein when a raw fuel material is loaded, a weight ratio between iron source and a solid fuel is changed for every loaded charge and concurrently the charge is separately loaded into a peripheral section of a furnace and a central section of the furnace, respectively.

Title: Turn indicator control unit for vehicle
Inventor: KAWADA HIROYUKI
IPC: B60Q1/40
Filed: 1984-02-20
Abstract: PURPOSE:To enable a turn signal given by flashing a turn signal lamp to be surely noted by other vehicles during high speed driving of a vehicle, by inversely proportioning an ON/OFF cycle of the turn signal lamp to a running speed of the vehicle in accordance with a signal from a left-turn or a right-turn detecting means. CONSTITUTION:When one of right-turn and left-turn signal lamp switches 1 and 2 is operated to change the course of a vehicle to left or right, a microcomputer 4 calculates a vehicle speed S in accordance with a vehicle speed pulse from a vehicle speed sensor 3 and obtains an ON/OFF cycle TA. The larger the vehicle speed S is, the smaller the ON/OFF cycle TA becomes. A duty ratio K is then determined. The larger the vehicle speed S is, the larger the brightness of the turn signal lamp becomes. ON commands are appropriately generated for driving the turn signal lamp to be lit until a time counter T reaches the value corresponding to a half of the ON/OFF cycle TA previously obtained. The lighting ON commands corresponding to the duty ratio K are subsequently sent to a turn signal lamp driving circuit 5 for the period TA/2, so that the turn signal lamp is lit according to the duty ratio for the period TA/2.

Title: Surface-coating agent for paper making an surface-coated paper
Inventor: YOKOYA KENJI
IPC: D21H19/10
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To increase a burst index and improve printability of the paper in offset printing by coating using an aqueous solution containing a carboxyl group-bearing polyacrylamide, a water-soluble aluminum compound and a chelating agent as a paper surface coating agent. SOLUTION: This aqueous solution containing (A) a carboxyl group-bearing polyacrylamide, (B) a water-soluble aluminum compound (as aluminum sulfate) and (C) a chelating agent is excellent in storage stability because it causes no thickening and gelation as a paper surface coating agent in a short time. In the drying step after paper is coated with this solution on its surface, aluminum reacts with the carboxyl group in the component A to largely reduce the solubility in water and eliminate the operation trouble on printing. In addition, a large amount of this coating agent can be applied to the paper surface through the film transfer printing technique and the quality of the printed matters is improved.

Title: Neutral point grounding method
Inventor: MOTOYAMA SHUICHIRO
IPC: H01C7/04
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a neutral point grounding method which has a good detection sensitivity of a ground relay like a low-resistance grounding method and which can prevent the damage of equipment due to overcurrent like a high-resistance grounding method. SOLUTION: A ceramic element (PTC element) 10 which has a positive temperature coefficient and suddenly increases its resistance value when its temperature reaches the phase transition temperature is connected to a neutral point N of a power system to ground the neutral point N through the PTC element 10. By this method, when an accident such as an earth occurs, overcurrent flows in the PTC element 10 in the initial stage because the resistance value of the PTC element 10 is small and therefore the detection sensitivity of a ground relay is not damaged. On the other hand, when overcurrent flows in the PTC element 10 after the passage of a certain period of time, the temperature of the PTC element 10 increases due to Joule heat generated when the overcurrent flows in the PTC element 10. When the temperature of the PTC element 10 reaches the phase transition temperature, the resistance value of the PTC element 10 suddenly increases and the current in the PTC element 10 is suppressed. Therefore, equipment connected to the power system are prevented from being damaged.

Title: Light intensity attenuator
Inventor: MORI YASUSHI
IPC: G02B26/02
Filed: 1990-02-15
Abstract: PURPOSE:To change the light intensity of a large output laser by simple operation by variably setting up the length of an optical path for passing light through a medium and variably setting up the attenuation factor of light intensity. CONSTITUTION:The optical path length in the medium is changed to change the attenuation factor of light intensity. Namely, light is made incident from the light incident face 2a of a cell 2 upon a divided room 6 and passes through a copper sulfate solution 7. Since the solution 7 is absorbing liquid for absorbing light, the light intensity of incident light 10 is attenuated in the solution 7 and then the attenuated light is made incident upon a divided room 8 through a diaphragm 5 and passes through distilled water 9 to be a non-absorbing solution. In the case of changing the attenuation factor of the light intensity attenuator 1, the cell 2 is moved in the vertical direction to the incident light 10 by rotating a micrometer 3. Thus, the attenuation factor of light intensity can be changed by the simple operation even in the case of a large output laser.

Abstract: PURPOSE:To relieve the load of a driving source, to gradually increas the load of a vacuum pump, and to enable to perform fine control by a method wherein, during the starting, the vacuum pump is raced without functioning. CONSTITUTION:The rotation force of a driving source is transmitted from a driving shaft 24 to a crank shaft 25, elevates a piston 34, and brings the interior of a negative pressure chamber 35 into a vacuum state. Along with rotation of the crank shaft 25, a shaft 10, a female rotor 12, and a male rotor 13 are rotated through a shaft 11 and gears 27 and 28. In which case, in case a pressure sensor 43 detects that a pressure on the suction port 18 side is as high as an atmospheric pressure, a valve mechanism 41 is opened by a control mechanism 44, and meanwhile, valve mechanism 40 and 42 are closed. This causes a suction port 18 to communicate with a passage 37 through a bypass passage 38, and causes racing of a rotary type vacuum pump 1 on the first stage side. If the pressure of the suction port 18 is decreased slightly, the valve mechanism 41 is closed, and meanwhile, the valve mechanism 42 is opened, and the vacuum pump 1 is functioned with half volume.
