Patent JP-H0762603-A (JP)
Title: Railroad maintenance robot
Inventor: SEKI YOICHI
IPC: E01B29/28
Filed: 1993-08-26
Abstract: PURPOSE:To fasten bolts with a certain constant fastening torque (a standard), by stopping fastening by an impact wrench when the rotary speed of a bolt socket has decreased to a specified rotary speed. CONSTITUTION:Fastening bolts 4 are erected loose in advance on a sleeper 1 and a carrier mounting a device is forced to travel on the rails 3. The position of fastening bolts is detected by a bolt sensor and an impact wrench is lowered. The fastening bolt 4 is rotated by the bolt socket 24 of the impact wrench 13 to tighten the fastening bolt 4. At this time, the rotary speed of the bolt socket 24 is detected. This detected value is input from a rotary encorder 29 into a microcomputer 31 for instance. When the rotary speed of the bolt socket 24 has come down to a specified value preset, the impact rench is stopped to finish fastening.

Title: Quantitative determination of iron in water and reagent for quantitative determination to be used therein
Inventor: KANEDA TAKAYUKI
IPC: G01N31/00
Filed: 1984-10-11
Abstract: PURPOSE:To make possible the easy quantitative determination of iron in water by ionizing and dissolving the insoluble iron in the water by an ionizing agent then bringing the dissolved iron of which the ion value is made uniform by an oxidizing agent or reducing agent into reaction with the resultant produce in the co-existence of a dye. CONSTITUTION:The insoluble iron in the test water is ionized by using, for example, oxalic acid as the ionizing agent and is thereafter unified to bivalent iron ion by using, for example, ascorbic acid as the reducing agent. The color former consisting of, for example, sodium p-phenanthroline disulfonate is added to the dissolved iron to form a color, then a dye consisting of, for example, 'brilliant blue FCF(R)' is added thereto. The color forming condition thereof is observed with the naked eyes as a change in the color tone in the co-existence of the dye, by which the concn. of the iron ion in the test water is quantitatively determined. The easy quantitative determination of the very slight iron in the water with high accuracy is thus made possible without using analyzing apparatus.

Abstract: PURPOSE:To remarkably improve the washing effect, by locally spraying water over the screen from the upper part to the lower part when the sieve openings of a vibrating screen clogged by the wet screening of a concd. coal-water slurry are washed with water. CONSTITUTION:When the sieve openings 3 of the vibrating screen 1 are clogged by the wet screening of a concd. coal-water slurry (expressed CMW hereunder), the supply of CWM is firstly stopped. Washing water is then sent to an uppermost-stage feed water pipe 8a, and sprayed from each spray nozzle 9a for a specific time. When the water spray is finished, washing water is sprayed from each second-stage spray nozzle 9b for the same period of time. Washing water is then sprayed from spray nozzles 9c and 9d in the same way. By these stepwise water sprayings, the concd. coarse CWM particles deposited on the screen surface 3 are separated into low-viscosity coarse CWM particles (oversize) and low-viscosity dilute CWM (undersize). The coarse CWM particles flow over the concd. CWM deposited on the lower screen surface 3 and drop into a trough 20. Meanwhile, the dilute CWM flows down over a mixing preventive plate 15 and drops into the trough 20.

Title: Connecting structure for fine tube flow passage
Inventor: AKACHI HISATERU
IPC: F28D15/02
Filed: 1988-08-30
Abstract: PURPOSE:To improve a sensibility remarkably, miniaturize a non-return function generating part and simplify the structure of a connecting structure by a method wherein the abutted connecting part of both fine tubes is constituted of an insertion welding type socket to employ the connecting structure provided with a non-return mechanism in the connecting part itself. CONSTITUTION:A spherical valve body is employed as a valve body 5 and a valve seat 6 is formed by machining or grinding the inner wall of the tip end of a fine tube 2 so as to be a tapered tube. The valve seat 6 may be formed by deforming plastically the tip end of the fine tube by punching it with a conical punch, whose tip end is ground sharply when the inner diameter of the fine tube is too small. The spherical body of sapphire or ruby may be obtained inexpensively as the spherical valve and the sphere of sapphire has a good compatibility to operating liquid such as water, Freon and the like whereby a connecting structure having a high reliability may be obtained. The specific gravity of sapphire is light as 3.98 and, therefore, a highly sensitive valve body may be obtained. The resistance to abrasion of sapphire is excellent and a reliability for a long year may be guaranteed. A relation between the value body and the valve seat in a loop type fine tube heat pipe necessitates not only the non-return function but also hardly vibrating property of the valve body, while easily separating property of the valve body from the valve seat upon ON/OFF operation of the valve becomes an important required performance.

Title: Power supply relay control method of microwave oven
Inventor: PAAKU UONNKON
IPC: H05B6/68
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To shorten a duration of spark generation, lessen the frequency of spark generation, and prolong the life of a relay contact by alternately turning off an electric power source relays at a specified time of the phase of power source voltage. SOLUTION: When input of clock signals with 50/60 Hz is inputted to a 50/60 Hz-clock input sensing part 12, a CPU 11 sets a 50/60 Hz clock input plug. At this point, if a plus-cycle-on-plug is already set, the CPU 11 judges that a power source relay is turned off in a plus-cycle of power source voltage before the time. Then, the CPU 11 sends out control signals to a relay on/off signal generating apparatus 14 and a power source relay on/off controlling part 18 to turn off the power source relay by sending a relay driving signal output with a delay by 2nπ+3/4π time of the power source voltage phase.  Also, in the case of no setting of the plus-cycle-on-plug, the CPU 11 judges that the relay is turned off in a minus-cycle of the power source voltage and sends out control signals to the apparatus 14 and the controlling part 18 to turn off the power source relay by sending a driving signal output with a delay by (2n-1)π+3/4π time of the power voltage phase.
