Title: Controlling method for electric railcar
Inventor: UENO TERUO
IPC: B60L15/22
Filed: 1988-04-28
Abstract: PURPOSE:To eliminate a push-pull phenomemon which occurs between wheels having different diameters of an electric railcar by calculating a wheel diameter correction coefficient on the basis of the wearing amount of the tread faces of wheels, and multiplying it by the output of a current limiting value pattern generator. CONSTITUTION:A distance l between a wheel 10 to be measured and a strain gauge 9 secured to a bearing box an axle having an always constant relative position to the axial center of the wheel 10 is measured, and is output to a wheel diameter corrector 8. The corrector 8 calculates a real wheel diameter WD at that time, and outputs a wheel diameter correction coefficient. Further, the output of a current limiting value pattern generator 4 is multiplied by that of the corrector 8, and input to a comparator 5. The comparator 5 compares the input value with the value of the rear armature current of the output of a real armature current measuring circuit 7, and outputs a cam axis stage advancing command to a cam motor rotation instructing circuit 6.

IPC: H01L21/28
Filed: 1988-04-28
Abstract: PURPOSE:To prevent an encroachment from being caused by controlling the concentration of a raw gas used to grow a tungsten film in multiple stages from low concentration to high concentration. CONSTITUTION:A film is formed while the concentration of a raw gas used to grow a tungsten film 15 is controlled in multiple stages from low concentration to high concentration. That is to say, the concentration of the raw gas is set to low concentration at an initial stage of a growth operation; a thin silicide is grown on the surface of a contact hole 14. After that, the concentration of the raw gas is set to a value which is higher than that in the initial stage; the tungsten 15 is grown. By this setup, when the tungsten film is grown selectively, one part of a diffusion layer 13 is eroded by the tungsten 15 at the initial stage of the growth operation of the tungsten; it is possible to prevent an encroachment from being caused.

IPC: E04G21/32
Filed: 1994-05-18
Abstract: PURPOSE:To dispense with any setting and working of a hinge, reducing the cost of an enclosure plate, and to improve the extent of efficiency in storage by installing at least a row of hole lines in a nearly central part of the cross direction at intervals in the longitudinal direction, and simultaneously forming each hole into square form. CONSTITUTION:An enclosure plate 1 is made up of a body part 2 being formed into flat surface shape and a flange part 3. In addition, a row of hole lines 5 consisting of rectangular oblong holes 4 linearly is installed in the central part in the cross direction at intervals. Next, a lateral side on one side of the hole lines 5 is clamped in a position turned down flatly and the other side is uplifted the other way. In succession, on the basis of plastic deformation in a hole line forming part, it is bent at an angle as specified. Then each hook hanger 6 is latched to a rising claw 3a formed in both flange parts 3. Subsequently, respective hook hangers 6 are engaged with a pipe framework in an upright position of the enclosure plate 1. With this constitution, cost is largely reduced, while in time of disuse, this enclosure plate is formed into flat shape, and thus any possible drop in conveyance and storage efficiency is fully preventable in this way.

Title: Doping concentration control method
Inventor: FUJII TOSHIO
IPC: H01L21/20
Filed: 1992-04-23
Abstract: PURPOSE:To control positive hole concentration in semiconductor mixed crystal without changing substrate temperature, V/III ratio, and supply amount of material containing imputies, by changing the uptake ratio of impurity atoms in the mixed crystal semiconductor by changing the composition of group III element in (AlGa)As mixed crystal semiconductor. CONSTITUTION:In composition in (InAlGa)As mixed crystal semiconductor is changed in the range from 0 to 10%, and Al composition is changed similarly in the range of 0 to 10%. Hence the uptake ratio of carbon atoms in the mixed crystal semiconductor or the activation ratio of carbon atoms entrapped by the mixed crystal semiconductor is changed. Thereby the positive hole concentration in the mixed crystal semiconductor can be controlled in the range from 5X10<16>cm<-3> to 5X10<20>cm<-3>. Thus the impurity concentration of mixed crystal is changed without changing substrate temperature, V/III ratio and supply amount of material containing impurities. A hetero junction bipolar transistor can be manufactured by applying epitaxial mixed crystal controlled in the above manner to a base layer 5.

Filed: 1982-06-16
Abstract: PURPOSE:To prevent leakage of oil without the decrease in the output of a sensor for oil pressure, by disposing a thin sheet of an amorphous magnetic alloy between a soft magnetic material mounted with a coil in a grooved part and a cover part having a transmission hole for the oil pressure, and mounting a preventing member for leakage of oil between the same. CONSTITUTION:A thin sheet 1 of an amorphous magnetic alloy having magnetostriction is sandwiched between a soft magnetic material 2 loaded with a coil 4 in a grooved part 24 and a cover part 3 having a transmission hole 31 for oil, whereby a magnetic circuit is formed. When oil pressure P is applied through the hole 31, stress is generated in the part corresponding to the part 24 of the sheet 1, and the magnetic resistance over the entire part of the magnetic circuit increases as the circuit is energized by the coil 4, whereby the inductance value corresponding directly to the oil pressure is obtd. An O-ring 5 disposed in the groove part 32 prevents the leakage of oil, and since the sheet 1 is pressed to the material 2, the wasteful generation of stress is eliminated, and the leakage of oil is prevented without the decrease in the output of the sensor for oil pressure.

Abstract: PROBLEM TO BE SOLVED: To bear a bending moment due to a seismic force and damping vibration by forming a plate body of three-layer construction containing a high molecular resin board between steel plates to a circular arc shape and fixing it to an intersecting portion between a column and a beam. SOLUTION: At each intersecting portion O of columns 2, 2 and beams 3, 3 constituting a framework of a building, both end portions of each damper 4 are fixed to a beam 3 and a column 2 with bolts 5 thereby creating an earthquake-resistive portion 1.

Abstract: PURPOSE:To realize a miniature integration with reduction of folding loss and thus to ensure the high-quality talking by supplying the output of the subtractor circuit and the signals on the 4-wire line of the reception side and then minimizing the ratio between the output level of the subtractor circuit and the signal level on the 4-wire line. CONSTITUTION:Reception signal A supplied from 4-wire line 4 via amplifier 15 is supplied to 2-wire line 1 via passive element 9 as well as transmitted to the positive input terminal (+) of subtractor circuit 11. While transmission signal B sent from line 1 reaches the positive terminal (+) of circuit 11 via passive adder circuit 8. At this instant, the signal level of the positive terminal (+) of circuit 11 features as Z0.A+Zn.B/Z0+Z1, where the impedance of line 1 and element 9 are Z0 and Z1 respectively. On the other hand, if the transmission property of variable transmission circuit 10 is set to Z0/(Z0+Z1) or its approximate property, the output of circuit 11 becomes nearly Z1.B/(Z0+Z1). Thus the folding loss can be minimized for signal A.
