Title: Searching method for accident point of aviation lighting circuit
Inventor: KASAHARA TOSHIO
IPC: G01R31/08
Filed: 1980-11-04
Abstract: PURPOSE:To spot the position of an accident by using a time difference between an induced voltage based upon discharge due to imcomplete contact and a reflected wave at a terminal which are detected through a cable for accident-point detection provided successively along a lighting circuit. CONSTITUTION:When imperfect contact occurs at the connection point between a transformer 2-2 for lighting and a cable 3-3, discharge is caused there and at the same time, a voltage is induced at a cable for accident-point detection. A part of the voltage is applied in the opposite direction to a detector and, after reflected at the other terminal 9 of the cable 5, it is applied to the detector 6. The time difference T between a voltage applied directly to the detector 6 and the voltage reflected at the other terminal 9 and then applied and the propagation speed (v) of signal are used to know the distance (l) between the accident point and terminal 9 from l=(vXT)/2. This method makes it possible to know a faulty point like imperfect contact which can not be detected by a bridge method.

Title: Loudspeaker
Inventor: TANABE AKIRA
IPC: H04R1/22
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To make an amplifier incorporated loudspeaker more small-sized, thinner, and better in heat radiation and to make it easy to connect a voice coil and an amplifier. SOLUTION: The space in front of a diaphragm 20 is used to arrange a magnetic circuit 24 and an amplifier 26 on the front side of the loudspeaker. Consequently, no special waterproof measure such as a shield plate need not be taken for the amplifier 26 and the heat radiation effect increases. Almost no component space is needed behind the diaphragm 20, and then the speaker is easily made small-sized and thin on the whole. Further, a lead wire 33 for connecting the amplifier 26 and voice coil 23 may be short and complicated wiring is unnecessary, thus even when the number of voice coils 23 is large, the operation for connecting the voice coils to the amplifier 26 is accurately and easily performed.

Title: Controller of electric rolling stock
Inventor: KAGA ATSUSHI
IPC: B60L9/18
Filed: 1979-11-27
Abstract: PURPOSE: To enable to reduce the magnitude of slip of a slipped induction motor by a method wherein the controller is so constituted as to suppress the increasing rate of an adder output by the action of a comparator.  
     CONSTITUTION: A differentiator is constituted of a capacitor 27 and a resistor 28, and the changed quantity of output of the adder 16 is supplied to an amplifier 29. When the output of the amplifier 29 is designated as -VINC, the -VINC is compared in the comparator 30 with a pattern Vp 2 31. When the absolute value of the -VINC becomes larger than the pattern Vp 2 31, the comparator 30 outputs a positive output to reduce the output of the adder 16. Therefore when the pattern Vp 2 31 is set at nearly the frequency increasing rate corresponding with the acceleration of the electric rolling stock, the frequency increasing rate is suppressed if the increasing rate becomes to excess for some reason. Namely if the induction motors 6W9 slip to get an acceleration more than the prescribed value by outward locks, the frequency increasing rate is reduced. Therefore the slip frequency does not become large, and the acceleration of the induction motors 6W9 becomes to be hard.

Title: Determining method for readout condition of radiation image information
Inventor: ADACHI YUMA
IPC: G03B42/02
Filed: 1985-07-15
Abstract: PURPOSE:To determine optimum readout condition by recognizing the size of a closed curve formed by connecting aimed points obtained so far in order as an irradiation field when the aimed points are searched for successively and the 1st aimed point is reached, and determining primary readout condition on the basis of preread image information in the irradiation field. CONSTITUTION:Digital data are obtained at respective positions on a sheet and differentiated to form a differential image and the contour of the irradiation field is detected on the basis of the differential image. One of presence positions of the irradiation field is detected as the 1st aimed point and the contour of the irradiation field is traced from the 1st aimed point to recognize the irradiation field. In this tracing, the position which has the largest differential value among peripheral positions adjoining to the 1st aimed point is searched for as the 2nd aimed point and then the position having the largest differential value among peripheral positions adjoining to the 1st aimed point except said aimed point (1st aimed point) is searched for as the 3rd aimed point. Thus when the position adjoining to the 1st aimed point is searched for as a new aimed point, the aimed points obtained so far are connected to form the closed curve, whose inside area is recognized as the irradiation field.

Title: Jig and device for positioning thin plate circular body
Inventor: SATO HIRONORI
IPC: H05B6/02
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To easily and surely load a thin plate circular body in a specified position by disposing a funnel body having an upper open slope hole nearly equal to the outer diameter of the thin plate circular body for its lower diameter and larger in its upper diameter than in its lower diameter close to the upper side of a specified position so as to be coaxial to its center. SOLUTION: Assuming that when the left end outer periphery B4 of a thin circular plate 1 is in contact with the circumference left end of the upper diameter D of a funnel body 11 and a right end outer periphery B3 is in contact with the surface of a substrate 31, an inclined angle of the thin circular plate 1 is θ and a static friction factor between the thin circular plate 1 and the substrate 31 is μ-tanϕs, based on f friction theory, the thin circular plate 1 is slid right because of its self weight when sin2θ is larger than 2sinϕs for its inclination angle. Thus, by setting the thickness T of the funnel body 11 such that the inclination angle of the thin circular plate 1 is larger than this θ, the thin circular plate 1 is lowered in the slope hole 12 of the funnel body 11 by its self weight and carried into the holding part 22 of a holding member 21.

Abstract: PURPOSE: To obtain a diffused region of the prescribed diffusion depth in a semiconductor device by composing an electrode of a polycrystalline or amorphous semiconductor layer and a metallic silicide contaiing effective impurity for a semiconductor substrate aranged on the layer.  
     CONSTITUTION: A hole of a field insulating film 12 formed on the surface of a semiconductor substrate 11 is formed. Then, a polycrystalline or amorphous Si layer 14 is covered on the substrate 11. Then, an Mo silicide layer 15 containing phosphorus is covered on the layer 14. Thereafter, 2-layer structure of the layers 15, 14 is patterned in desired shape. Subsequently, the substrate 11 is heat treated to impregnate the phosphorus in the layer 15 into the layer 14 to diffuse it into the substrate 11, thereby forming an N +  type region 13. At this time an oxidized film 16 is formed on the exposed surface of the layers 15 and 14. With this configuration, since the diffusion depth of the region 13 can be maintained constantly, a stable withstand voltage charateristic with less irregularity can be obtained.
