Title: Dust radioactivity monitor apparatus and method for washing filter paper
Inventor: GOTO YOSHIMI
IPC: B01D46/42
Filed: 1990-11-29
Abstract: PURPOSE:To reduce the amount of the waste in a radioactive rays control area, in a dust radioactivity monitor apparatus measuring the radioactive concn. of the dust in the radioactive rays control area, by providing a washing means allowing air to flow to the filter paper after the measurement of radioactivity in the direction opposite to that at the time of dust collection. CONSTITUTION:Filter paper is delivered to a position 2b from a filter paper holder 1 and the air of a place 9 where radioactive concn. must be measured is sucked by a pump 3 to collect dust on the surface of the filter paper. Next, the filter paper is transferred to a position 2c and, after the radioactivity in the dust is detected by a radioactivity detector 4, the filter paper is transferred to a position 2d. At this position 2d, air is sprayed to the filter paper in the direction opposite to the direction at the time of the collection of dust at the position 2b to wash the filter paper. Since the exhaust air of the pump 3 used in dust collection is used as the air for blowing off the dust, dust is already perfectly removed when the air sucked by the pump 3 passes through the filter paper at the position 2b and the filter paper is not contaminated by exhaust air. The dust at the position 2d is discharged to the outside 10 along with air and the filter paper after washing is set to the uppermost stage 2e of the filter paper holder 1.

Title: Sleeper surveying apparatus
Inventor: HIRANO MAKOTO
IPC: G01C7/04
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To survey safely and highly efficiently by setting a distance detecting means for detecting a distance to an object below at a scanning arm projecting at right angles to a running direction of a truck, detecting by a different detecting means when the distance-detecting means comes to an end of a sleeper, and instructing a worker to survey by a detection signal. SOLUTION: A worker pushes a manual operation bar 8b to run a moving truck 8 on a rail 5. An end face 2a of a sleeper 2 is detected by an end face detection sensor 11. When a detection signal of the sensor 11 changes from an OFF state (detecting the sleeper 2) to an ON state (not detecting the sleeper 2), and when the detection signal changes from the ON state to the OFF state, it is judged that the apparatus is at a position to survey the sleeper 2 at the front side and the opposite side, respectively. When the apparatus is located to survey the sleeper at the front side, an operation control part 17 outputs a control signal to a survey instruction part 18 at all times.  When the apparatus is located to survey the opposite sleeper, the control signal is output when the truck 8 is moved to a predetermined position which is detected by an output signal from a distance-measuring roller 16. Accordingly, the worker is informed that a sleeper survey device 7 is at a position capable of surveying the sleeper, e.g. by means of a lamp or the like. The sleeper 2 can hence be surveyed by the sensor 10.

Title: Semiconductor device
Inventor: TODA TOSHIYUKI
IPC: H01L29/78
Filed: 1993-12-27
Abstract: PURPOSE:To improve controllability by a gate electrode by combining a depletion layer generated by a second conductive type semiconductor region and a depletion layer generated on a first conductive type semiconductor conductive semiconductor substrate surface below a gate electrode at the operation time when a desired voltage is impressed on the gate electrode and the source - drain regions. CONSTITUTION:When voltage to be impressed on a gate electrode 5 is gradually raised up in the negative direction, positive holes are generated on the N-type silicon substrate 1 directly under the gate electrode, a positive pole channel 13 is generated. Then, the source - drain are electrically connected, a current flows between the source and the drain. Thereby, since a p-type semiconductor region 9 included by the n-type silicon substrate 1 is formed under the gate electrode 5, the width of a depletion layer 11 widens. That is, the depletion layer 11 to be generated by the p-type semiconductor region 9 and the depletion layer 11 at the operation time come in contact with the depletion layer to be generated in a p-channel region. Accordingly, an electrostatic capacity between the channel and the substrate decreases, thus allowing improvement of controllability by the gate electrode.

Abstract: PROBLEM TO BE SOLVED: To provide a float-arm type unit gauge for tank which is reduced in working space to the front end side from the center of rotation of the float of the gauge so as to reduce the size of the main body of a tank. SOLUTION: When a float 3 moves upward or downward on the surface of a liquid poured in the main body 2 of a tank in accordance with the vertical movement of the surface level of the liquid, a float-side arm 1a moves upward or downward along an arm guide 6, causing a stay-side arm 1b which is slidably engaged with an arm guide 7 so that the arm 1b can turn around a shaft 5 in the axial direction. Therefore, the float 3 can work linearly in the vertical direction and the size of the main body 2 of the tank can be reduced by reducing the working space of the float 3 to the front end side.

In the same way, phase voltages Eb and Ec are individually inputted and their running averages are independently calculated to obtain phase voltages V(N). As a result, the response of the control of a control angle to the occurrence of a transmission failure, etc., can be improved.
