Title: Method for removing water from mounted printed circuit board
Inventor: SHIBANO YOSHIHIDE
IPC: B08B5/00
Filed: 1989-07-28
Abstract: PURPOSE:To easily remove the water adhering to a mounted circuit board without deteriorating the quality of the board by forming a through hole from the surface to the back side of the board and causing the water to drop down by means of the air pressure of compressed air and gravity and, at the same time, sucking air from below the circuit board. CONSTITUTION:Since a mounted printed circuit board 1 is carried leftward from the right side on a mesh belt 2 and, at the same time, clean air is blown on the board 1 from an air blow pipe 3, the water adhering to the surface of the printed circuit board 1a, IC 1c, capacitor 1d of the mounted circuit board 1 and the water staying in the gap between the circuit board 1a and IC 1c, etc., is blown off. The water removed from the mounted circuit board 1 flows into a drain hole 1b after flowing on the circuit board 1a. By means of the air pressure of the compressed air blown from the pipe 3 and gravity, the water drops down from the printed circuit board 1a. Moreover, since air is sucked from below the circuit board through a suction duct 4 simultaneously with the air blow from the pipe 3, the water dropping down from the drain hole 1b is sucked by a suction nozzle 5. Thus the water can be removed more easily.

Title: Method for judging completion time of iron tapping of blast furnace
Inventor: WAKITA SHIGERU
IPC: C21B5/00
Filed: 1994-08-23
Abstract: PURPOSE: To stably, accurately and quantitatively judge the completion time even if the variation in the producing condition of gas is developed by continuously measuring CO2 concn. and O2 concn. in the gas spouted from an iron tapping hole, respectively, at the time of tapping the molten iron in a blast furnace. CONSTITUTION: The molten iron is tapped from the iron tapping hole 2 of the blast furnace 1 and the in-furnace gas 3 spouted from this hole is fed to a gas analyzer 9 through a gas supplying hole 8, and the CO2 , concn. and the O2 concn. in the gas are continuously measured, respectively. At the end stage of the iron tapping, in which the level of the molten iron slag 5 in a furnace hearth 4 lowers, the spouted gas quantity from the iron tapping hole 2 is increased and also the CO2 concn. is increased and on the other hand the O2 concn. is decreased. When the CO2 concn. continuously becomes a prescribed concn. or higher, e.g. >=6% and further, the O2 concn. continuously becomes a prescribed concn. or below, e.g. <=1% for >=3min, it is judged that the iron tapping in the blast furnace completes.

Title: Method for filling adsorbent into artificial organ in vacuo
Inventor: KUKI KAZUO
IPC: A61M1/36
Filed: 1987-08-05
Abstract: PURPOSE:To prevent the occurrence of bubbles in an artificial organ that are the defect thereof, and to control them, if present, to less than an allowable value, by evacuating an integral container consisting of the artificial organ and an auxiliary metering vessel. CONSTITUTION:A container which is an integral body of an artificial organ and an auxiliary metering vessel connected tight to an opening of the artificial organ is evacuated by evacuating means such as a vacuum pump. The integral container is filled with a prescribed volume of a solution, and then with an intimate mixture of a given concentration of an adsorbent with a solution up to the prescribed total volume of a mixture of said solution with said intimate mixture. Then, an excessive solution is discharged out of the artificial organ from the mixture, thus making the adsorbent precipitate into the container. The container is evacuated at a certain point of this process by the evacuating means and thus cleared of bubbles present in the mixture or air dissolved in the mixture. As a result, it is possible to allow no bubbles present in the adsorbent of a merchandized artificial organ, and to control them, if present, to less than an allowable value.

Title: Eccentric winding machine for wire material
Inventor: ITO NOBORU
IPC: B65H54/76
Filed: 1986-08-25
Abstract: PURPOSE:To prevent the entanglement of wire materials as taken out by constituting the winding system wherein the wire materials as fed at a constant speed from the upper side of a winding carrier are wound about the carrier mounted on an eccentric turntable under eccentric rotation with gradual fine rotation. CONSTITUTION:A wire material as paid out at a constant speed is eccentrically wound via the eccentric rotation of an eccentric turntable. Namely, as a rotary disc 5 turns, a rotary axis S rotates and causes the rotation of a rotary disc 6 at the upper end of a rotary axis U via a gear (c), another gear (d), a rotary axis T, another gear (e) and another gear (f). In this case, if the number of gear teeth is so selected as to be the gear (a)< the gear (b), the gear (c)< the gear (d) and the gear (e)< the gear (f), it follows that one complete turn of a rotary axis R causes the fine turn of the rotary axis U. Therefore, when the rotary axis R turns once for winding the wire material, this material on the rotary disc 6 is slightly dislocated, thereby giving a winding pattern as illustrated herein. Consequently, the wound wire materials when drawn out are not entangled with each other.

Filed: 1991-07-11
Abstract: PURPOSE:To make a vehicle airconditioner unnecessary to actuate an oxygen enriching device more than needed by providing a mode switching device which selects either the mode of circulating inside air or that of introducing fresh air, and detecting the oxygen concentration in the cabin of a vehicle and the concentration of contamination in the fresh air, and performing actuation of the oxygen enriching device and selection by the mode switching device according to the results of this detection. CONSTITUTION:Oxygen-enriched films 7 are stored in the box of an oxygen enriching device and air introduced into the box through a filter 10 is adsorbed to the oxygen-enriched films 7 and oxygen and nitrogen are transmitted therethrough and then blown into the cabin of a vehicle via a vacuum pump 5. Sensors are used to determine whether or not the oxygen concentration in the cabin is insufficient and whether or not the concentration of contamination in fresh air is negligible. When the results of this judgement show that there is oxygen deficiency in the cabin and that the fresh air is clean, a mode switching device is switched to the mode of introducing fresh air and the oxygen enriching device is not operated. When there is oxygen deficiency in the cabin and the fresh air is contaminated, the switching device is switched to the mode of circulating inside air and the oxygen enriching device is operated and thereby wasteful actuation of the oxygen enriching device is prevented and the use of clean fresh air is made possible.

IPC: H01S5/00
Filed: 1988-08-08
Abstract: PURPOSE:To make a narrow distribution of a light emitting wavelength by constituting a well layer in a grated layer whose composition rate varies gradually. CONSTITUTION:A well layer 2 which is formed between nondoped AlGaAs barrier layers 1, 3 is made in a grated layer whose composition rate of Al varies gradually. Then a quantum well whose potential shape changes smoothly is formed.

IPC: G01N23/223
Filed: 1988-08-08
Abstract: PURPOSE:To shorten the time required for element identification by providing means for rearranging the wavelength data of the respective elements stored in a wavelength chart memory to the appearance frequencies added by an appearance frequency adding means. CONSTITUTION:The identification of the sample component elements is executed by contrasting the respective peak wavelength and intensity ratios of the main peaks and sub-peaks of the characteristic X-rays of the respective elements stored in the wavelength chart memory 6 after the measurement data of the X-ray spectra with the sample from an X-ray detector is stored into a measurement data memory 4 via a control part body 2. One appearance frequency is added to the wavelength data of the identification element of the memory 6 in the appearance frequency adding means 8 at every identification when all the component elements of the sample are identified. The wavelength data of the respective wavelengths of the memory 6 are then rearranged in order of the larger appearance frequencies in a rearranging means 10. The wavelength data are, therefore, contrasted in order of the elements having the higher probability of the appearance frequency in case of making qualitative analysis of the same kind of the sample in the next time. The time required for the identification is thus shortened.
