Title: Ac exciting generator motor apparatus
Inventor: BANDO AKIRA
IPC: H02P9/10
Filed: 1988-03-09
Abstract: PURPOSE:To prevent the armature frequency of an AC exciting synchronous machine from abruptly increasing by applying a correction signal for suppressing a slip frequency to a predetermined value to an effective power controller when the slip frequency exceeds a set value. CONSTITUTION:A phase detector 9 detects a slip phase thetas between the voltage phase thetav of an AC power system 1 and the rotary phase thetar of an AC exciting synchronous machine.

IPC: H01L21/205
Filed: 1995-03-15
Abstract: PURPOSE: To achieve an upper dielectric surface having a 'flow angle' lower than a specified angle by increasing RF power over a specified watt, heating a wafer at a specified temperature or above in an oxygen atmosphere and subjecting the material to reflow simultaneously with density increasing process. CONSTITUTION: A dielectric layer 34 is formed on an electrode 22 in a PECVD chamber 10 using RF power. When the RF power is increased over 950 W and a wafer is heated at 800 deg.C or above in oxygen atmosphere, the flow angle is set at 10 deg. or less. A gas source material is then placed in the chamber 10 and RF power is applied to the electrode 22 from plasma. The majority of plasma deposited layer is composed of silicon dioxide. Consequently, the flow angle is decreased and the characteristics of plasma deposited material are enhanced. More specifically, an intermediate silanole is formed on the surface of the substrate.

Abstract: PURPOSE:To detect the abnormality of a power source part, by a method wherein a test pattern (full load printing pattern data) is mounted to an interior and a full load test is performed by using the same while the output voltage of the power source part is checked at this time. CONSTITUTION:When a control button 7 is pushed down and a change-over part 8 is changed over to a contact (b), the test pattern data Pm of memory 6 is supplied to drivers D1-Dn from a printing control part 5 and printing reaching max. load is performed by a printing head 3. When the output voltage V of a power source part 4 reaches a predetermined value or less at this time, the power source part 4 is found to be inferior. As a means for detecting this, the output voltage V of the power source part 4 is divided by resistors R1, R2 and the obtained voltage (v) and reference voltage VR are compared by a differential amplifier 9. When voltage (v) comes to the reference voltage VR or less, the potential in the output side of the differential amplifier 9 is changed and, therefore, an alarm generating part 10 is started to output an alarm signal A. This alarm signal A lights a lamp L and sounds a buzzer BZ to inform the abnormality of the power source part 4.

Abstract: PURPOSE:To correct the control error of torque due to the variation in the temperature even at a starting time or low speed time by estimating the temperature rise of a secondary coil from the secondary copper loss and correcting the angular slip frequency with the result. CONSTITUTION:When a torque current which corresponds to the instructed torque value is outputted from a circuit 2, an output which is proportional to the secondary copper loss is calculated by a secondary copper loss calculator 21. A primary delay system 24 having a subtractor 22, an integrator 30 and an amplifier 23 estimates the temperature rise of the secondary coil by regulating the gain of the amplifier 23 and hence the time constant of the system. After this output is added by an adder 27 with the output of the calculator 26 which inputs an output of a temperature sensor 25, it is applied to a tertiary copper loss calculator 21 and a multiplier 12. The multiplier 12 adds the output from a circuit 4-3 for generating a signal of the slip angular frequency and the output of the adder 27 and supplies its output to a motor drive circuit 6.

Abstract: PURPOSE:To realize the band inverting multiplexing of high-definition information by performing a frequency shift once and at a low carrier frequency by shifting the frequency of a return part generated at a sampling frequency and multiplexing it in a current band, and using a filter which passes only the part. CONSTITUTION:A transmission side separates a luminance signal Y into a luminance signal YL of <=4.2 MHz and a luminance signal YH of 4.2-6.3 MHz by a LPF 2 and a subtracter 3. A YH signal modulating circuit 4 imposes carrier suppression amplitude modulation on the YH with 1.7 fsc. Then the modulated YH'' is extracted by a HPF 6. A multiplier 7 multiplies the YH component by a coefficient R according to motion found by a motion detecting circuit 1. A color signal is passed through LPFs 9 and 10 with respect to an I.Q signal and modulated by a color signal modulating circuit 11. A mixing circuit 8 adds the color signal C and a high-definition signal YH'' to the YL signal. Consequently, the band inverting multiplexing of the high-definition information is performed by performing a frequency shift once and the sampling frequency need not be increased.

Abstract: PURPOSE: To surely clean the inside of a bar for tubular and to prevent the disturbance of an in-furnace atmosphere occurring in a purging gas by mounting gas receiving port members to which advanceable and retreatable gas delivery port members are pressed at both sides of a tray to be placed with a bar for tubular. CONSTITUTION: The tray 21 is placed on rollers 12 for transportation horizontally installed in the transverse direction of a preheating chamber 11 of a heat treating furnace and the long-sized pipe coil-like bar A for tubular wound in a coil form is placed thereon. The one end and other end of the bar A for tubular are connected to the gas receiving port members 31, 32 mounted at both sides of the tray 21. Cylinder rods 41, 42 are advanced by cylinder barrels 43, 44 to press the gas delivery port members 51, 52 mounted at their front ends on the gas receiving port members 31, 32. The purging gas from a gas supply source 55 is passed in this state to the outside of the furnace in the route of the gas delivery port member 51 → the gas receiving port member 31 → the bar A for tubular → the gas receiving port member 32 → the gas delivery port material 52.  At this time, the tray is sufficiently fixed and the gas delivery port members and the gas receiving port members come into tight contact with each other and, therefore, the leakage of the purging gas into the furnace from between both does not arise.

Abstract: PURPOSE:To drill a hole without causing burrs or peeling due to reinforcing fibers by forming a twisted groove into a helical shape advancing in the direction of rotation according as it goes from the tip side toward the base end side, shaping the outer peripheral surface of a drill body into a cylindrical, smooth curved surface, and providing a specified back taper to it. CONSTITUTION:A twisted groove 2 is formed into a helical shape going in the direction of rotation according as it advances from the tip side toward the base end, the whole outer peripheral surface of a drill body 1 is shaped into a cylindrical, smooth curved surface, and a back taper ranging from 0.4 to 2mm for 100mm in the axis direction is provided to the outer periphery of the drill body 1. As a result, axial rake angle of a cutting edge 3 becomes minus, and reinforcing fibers can be cut off as if they were cut with scissors. Thus, no reinforcing fiber remains on the surface machined by the cutting edge 3, and since frictional resistance between the drill body 1 and a hole is small due to the back taper and the reinforcing fibers can be cut with good cutting action, generation of burrs or peeling on the edge part and the inner periphery of the hole can be efficiently prevented.
