摘要： PROBLEM TO BE SOLVED: To provide a system that has high safety and rapidly removes an obstacle when the obstacle is not enough thick to be sensed by a door end sensor in closing a door of a platform and thus a perfectly closing state of the door occurs. SOLUTION: The platform door control system comprises the platform door 3 disposed in the platform of a vehicle, the door end sensor 15 for detecting that the obstacle is grappled by the door, and an electromagnetic lock 17 for locking the door after the completion of closing of the door. When the obstacle lying out of a sensing range of the door end sensor is grappled by the door after the completion of closing of the door, the door end sensor is made to sense the obstacle by moving the obstacle, and a microcomputer controller 13 reopens the door from the grappled state of the obstacle by the door to a certain distance without releasing the door lock, and then closes the door again.

摘要： PROBLEM TO BE SOLVED: To provide a radiation shield material having no adverse effect to human bodies of production workers and to the environment and high radiation shield capability. SOLUTION: The shield material contains vulcanized rubber and bismuth powder. A shape is given to the bismuth powder by the vulcanized rubber and radiation is effectively shielded by the bismuth powder. Since bismuth is not harmful as seen in lead, no adverse effect is expected for human bodies of production workers and to the environment. It is desired to cool the mixture of non-vulcanized rubber and a vulcanizing agent before mixing the bismuth powder so as not to cause bridge reaction in the non-vulcanized rubber by the cause of heating due to mixing of bismuth.

摘要： PROBLEM TO BE SOLVED: To provide a method wherein a probe card, in which many probes having a small contact area with an electrode pad are arranged at narrow pitches is manufactured with satisfactory efficiency. SOLUTION: Grooves in the required number of portions of probes are formed on the surface of a substrate composed of silicon (process S100). A conductive material is formed in the grooves, and the probes are formed by using the grooves as a mold (process S120). After that, the substrate is removed, in such a way that parts up to prescribed lengths of the probes are exposed, and a probe base composed of the remaining substrate is formed (process S140). Thereby, a plurality of probes can be formed collectively on the probe base, and the probe card can be formed with satisfactory efficiency, even if the number of probes is increased.

摘要： PROBLEM TO BE SOLVED: To provide a rotatory flowing aerator wherein activated sludge and a nitrifying bacteria-holding carrier are difficult to be settled, and if settled, they can be easily dispersed in water to be treated. SOLUTION: A rotatory flow is generated between left and right chambers 34 and 36 wherein up and down parts communicate with each other by bordering a partition panel 38 by discharging compressed air from an aeration tube 24 to a microbe stored in an aeration chamber 30 and water to be treated containing a carrier by which the microbe is held. Then, a bottom part shape of the aeration chamber 30 is formed in an inversely triangular section in a flow direction of the roratory flow, and a central part of the bottom part of the aeration chamber 30 is made low. A reflux apparatus wherein primary treated water sucked from an apparatus wherein primary treated water sucked from an opening part formed in the central part is refluxed above the aeration tube 24 inside the aeration chamber 30. A suction fan 66 disposed to an outlet 64 at a tip part of the reflux apparatus is rotated, and a water flow is generated from the opening part 60 to the outlet 64. Thereby, activated sludge and a nitrifying bacteria-holding carrier which are settled to the bottom part of the aeration chamber 30 can be surely dispersed in the water to be treated.

摘要： PROBLEM TO BE SOLVED: To regulate the backwashing speed of the filter member of a natural equilibrium filter basin by a simple apparatus construction. SOLUTION: Two first and second siphon pipes 10, 20 are parallelly provided in place of one siphon pipe 7. A large quantity of backwashing water is discharged to a washing drain sewer 8 from a water collecting sewer 4A through the first and second siphon pipes 10, 20 to regulate the water level in the water collecting sewer 4A so as to make the same less than the height of a trough 4C and the filter member 4B is backwashed in this state. Just before a backwashing process is completed, a small quantity of backwashing water is discharged to the washing drain sewer 8 only through the first siphon pipe 10 and the water level of the water collecting sewer 4A is regulated so as to be made larger than the height of the trough 4C. By this constitution, the water level difference between a filter basin 4 and the filtered water communication sewer 5 is changed to regulate a backwashing speed.
