Title: Method for controlling servo motor
Inventor: IWASHITA HEISUKE
IPC: H02P29/00
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of overshoot at the position of a machine movable part when controlling the position through a full closed loop system. SOLUTION: Bell type acceleration/deceleration processing is performed to a moving command. When an output P1 of acceleration/deceleration processing on the 1st stage becomes '0' (S4 and S5), a counter C is turned to '0', a coefficient k3 of incomplete integration is turned to a small value ('0' for example) and a torque limit value TL is turned to a small value TLL (S6). Since the incomplete integration is performed (S11) and a torque command value TC is limited to a small value, the output of a servo motor is reduced and the torsion of a mechanical system between the servo motor and the machine movable part is canceled.  When both outputs P1 and P2 of acceleration/ deceleration processing become '0', the coefficient k3 is set to a little larger value, the torque limit value is increased (S17), incomplete integration is performed (S11) until the counter reaches C0 (S10), the output torque of the servo motor is gradually increased and the machine movable part is fixed at the commanded position. Since the torsion of the mechanical system is canceled and positioning is performed, overshoot can be prevented.

Title: Thin motor
Inventor: KISHIDA KIMIO
IPC: H02K21/22
Filed: 1994-08-16
Abstract: PURPOSE: To enable the suppression of vibration and precession due to the distortion in coil current, by displacing in the axial direction at least one of the teeth of an armature, except ones adjacent to rotational position detecting magnetism sensors. CONSTITUTION: An armature 14, radially formed by laminating a plurality of magnetic plates, is provided with a plurality of teeth. The outermost portions of adjacent teeth 14a-14c of them are bent and displaced toward base 19 by a dimension of L. Letting the thickness of each tooth be D and the amount of the displacement be L, the amount of bending the teeth 14a-14c is controlled so that the relation of 0.1<L/D<2 will hold. Rotational position detecting magnetism sensors 211 , 212 , 213 for detecting the position of rotor are installed on the base 19 at equal intervals between teeth, other than the bent and displaced teeth 14a-14c, so that they will not adjoin the teeth 14a-14c.  Thus a large attractive force F2 of a magnet 11 is exerted on the side 14a, and the rotor continues to rotate in a constant slanted position even if there is any clearance between the rotary shaft 13 and the bearing 18 in a bearing unit; no precession is caused.

Title: Flux for submerged arc welding
Inventor: SUGIOKA ISAO
IPC: B23K35/362
Filed: 1981-12-25
Abstract: PURPOSE:To improve the appearance and shape of beads and pock mark resistance in high speed inclined position welding by mixing powder of a deoxidizing agent which is limited of grain size constitution with a fused flux for submerged arc welding limited of bulk density. CONSTITUTION:Powder of a deoxidizing agent of which the bulk density is made 0.7-1.3 times the bulk density of a fused base flux consisting essentially, by weight, of 35-60% SiO2, 20-35% MnO, 10-30% MgO, 2-15% CaF2, and the content of 12-48 mesh particles is made >=50% is mixed at 0.3-5W% with said base flux. The reasons for limiting the bulk density of the flux and the grain size constitution of the deoxidizer lie in that if the 12-48 mesh particles are <=50%, the flux and the deoxidizing agent are vulnerable to sepn. and uneven distribution, and the prevention of pock marks is uncertain. If the bulk density exceeds the limited range, the defects similar to the defects mentioned above are produced.

A data window is supplied to a multiplier 35 through the line 22 and the filter coefficient of the device 53 is multiplied. The ghost signal is removed by operating on convolution and it is inversely converted. The video signal string from which the ghost signal is removed by the time delay effect of a line 45 is outputted. Thus, the number of the filters can be reduced.

Abstract: PURPOSE:To prevent generation of a leak current between n<+> diffused layer and P type substrate by opening a contact hole, forming a high concentration As layer n<++> at the bottom thereof and then selectively burying the contact hole through reaction of a gas including a metal and the Si substrate. CONSTITUTION:After forming an n<+> diffused layer 2 on a P type silicon substrate 1, an insulating layer 4 is deposited and a contact hole 5 is opened. Next, As is implanted to the bottom of the hole 5 to form an n<++> layer 3. Thereafter, WF6 is selectively deposited in the contact hole 5 through reaction of a gas reduced by Ar(argon) and SiH4. In this case, reduction of silicon occurs simultaneously with reduction of silane and tungsten W is grown into the Si substrate. With formation of As layer of 4X10<28>cm<-3> or more, amount of growth can be reduced to about 40nm or less and generation of a leak current between the layer 2 and substrate 1 due to the growth of W into the Si substrate can also be prevented. Thereby, disconnection is never generated even when electrodes and wirings are formed and reliability such as electromigration resistance can also be improved.
