Title: Prevention structure for tunnel noise of rapid train
Inventor: KITATE TAKAO
IPC: E21F1/00
Filed: 1994-05-23
Abstract: PURPOSE:To prevent the noise trouble caused by a train in motion in the case the train passes through a parting tunnel and to demonstrate a very high speed performance by controlling the operation of an air-curtain with a timer by the passage of the rapid train. CONSTITUTION:An air-curtain 8 and an exhaust port 9 are provided to a parting tunnel 2, the air curtain 8 is interlocked with a timer loaded sensor 10 provided this side of an entrance of the tunnel, and when a rapid train 7 passes by the sensor 10, the air curtain 8 is automatically operated to start to ventilate air, two wind currents are released to form a wind current wall, and the exhaust is discharged outside from an exhaust port 9. High sounds generated in the case a rapid transit train 7 enters the tunnel 2 are cut off by the wind current wall of the air curtain 8, and the sounds are deadened to the utmost. After the generation of high sounds, the air curtain 8 automatically restores its stop timer by the timer of the sensor 10, the wind current wall is disappeared when the train 7 passes through the parting tunnel 2, so that the train may run through without trouble.

Title: Multi-selection fault detecting method for memory device
Inventor: MATSUO HIROSHI
IPC: G11C29/00
Filed: 1984-07-11
Abstract: PURPOSE:To detect multi-selection fault by ANDing of the OR of level of 2<n-1> pieces of the lines to be selected by address patterns of the first subset of 2<n> pieces of lines to be selected and the OR of level of 2<n-1> pieces of lines to be selected of the second subset. CONSTITUTION:W0 and W3 of lines 2 to be selected are simultaneously selected against input of address. Likewise, when W2 of lines 2 to be selected of address pattern, W1 is selected, too, when W4 of lines 2 to be selected of address pattern is selected, W7, too, when W5 of the selected line 2 of address pattern is selected, W6, too. Therefore, in such a condition, OR P1 and OR P2 become ''1'' together, and AND Q becomes ''1''. In case that the lines 2 to be selected are selected normally, AND Q becomes ''0'' against input of every address pattern, and in case that multiselection fault exists, AND Q becomes ''1'', which makes it possible to discriminate whether or not multi-selection fault exists, by value of AND Q.

Abstract: PURPOSE:To increase the strength below a neck by forming a washer unto a sleeve, its receiving surface into a stepped taper surface with sharp and gentle slopes, and also the pressing surface of a tightening nut into a taper surface made in contact and engaged with the sharp slope of the washer. CONSTITUTION:A head connection joint is composed of a sleeve washer 4, in which a pressure receiving surface 5 is formed into a gentle slope of 5'' at its rear along a sharp slope of 5' from a top end, and a tightening nut 3, in which a pressure receiving surface 6 made in contact and engaged with the sharp slope of 5' side is tapered. By this, the mechanical strength of a head 2 below its neck can be increased by increasing the curvature below its neck or making the form below the neck into a slant wall of large diameter, without losing the downsizing of the washer 4. Also the weight of the bottom wall of the tightening nut can be reduced by forming the pressure receiving surface 6 into a thin wall and, because a volume of the connecting head 2 is small, pockets of flow holes produced in plastic working can be reduced to prevent cavitation erosion from developing.

Filed: 1989-06-07
Abstract: PURPOSE:To output pickup information with high reliability even when defect is relieved by constituting each of lots of photoelectric conversion sections (pixel) arranged on a photodetector face with plural divided cells and using the divided cells by switching. CONSTITUTION:If one pixel such as pixel P1 has a defect while only the system A is in operation, a system A clock generating circuit CA is paused, a system B generating circuit CB is actuated instead to relieve the defect. That is, the defect is relieved by replacing two division cells P1A, P1A constituting the pixel P1 having a defect into a cell P1B. Thus, the pixel and picture element information correspond to each other correctly at all times independently of execution of defect relieve. Then accurate pickup information is outputted even with the defect relieve.
