Title: Rotor for electric motor
Inventor: SAWANISHI HIROHISA
IPC: H02K1/27
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To prevent displacement between layers and tilting of a laminate, by providing one or total part of a cut raised protrusion on a line connecting an inter-pole part mutually between magnets and a rotary shaft center, also inserting a caulk pin to an iron core part outside the magnet. SOLUTION: A clamp means 6 in an iron core 1a is provided on a line 20 connecting an inter-pole part 19 mutually between magnets and a rotary shaft center O. In the clamp means 6, an irregular part by a cut raised protrusion, provided in each thin iron plate at punching time, is secured to be entangled mutually by the thin iron plates adjacent in a layered direction. In an iron core part outside a magnet 3a, by narrowing a width of a bridge part 8a, because of easily generating displacement between layers and tilting of a laminate, a caulk pin 7 is inserted. Since this caulk pin 7 is firmly caulked on an end plate 9 mounted in both end parts of the iron core 1a, displacement and tilting are compressed by the end plate 9 and corrected to a certain degree.  Simultaneously through the end plate 9, securing strength for centrifugal force resistance in an iron core part outside the magnet 3a is maintained.

Abstract: PURPOSE:To attain excellent ghost elimination for a differential type device, by detecting a DC component of an output signal of an error signal amplifier circuit  and amplifying the signal by taking this detected DC current as a center. CONSTITUTION:The amplifier circuit 18 is formed as a differential circuit. A signal from a subtraction circuit 13 is applied to an input terminal of the circuit 18 and a part of an output signal of the circuit 18 is applied to a capacitor 33 through a buffer circuit 31 and a switch 32, and a terminal voltage of the capacitor 33 is applied to a bias terminal of the circuit 18 through a buffer circuit 34. The switch 32 is turned on with a pulse from a sampling pulse forming circuit 30. In this device, when the switch 32 is turned on, the DC level of the signal just before the detection section is kept in the capacitor 33 by keeping an output potential to the capacitor 33. This DC level is taken as a bias potential, allowing to perform amplification at the circuit 18 centering this DC level.

Inventor: OOYAMA MASAYA
IPC: G02B5/18
Filed: 1986-02-24
Abstract: PURPOSE:To attain linear scanning by arranging plural scanning lenses around the periphery of a rotary disk along the peripheral direction. CONSTITUTION:Many scanning lenses 12 are arranged and fixed on the outer periphery of the rotary disk 1 along the circumference of the disk 1.

Abstract: A hybrid circuit arrangement for a telecommunication system includes a transformer having a first and a second partial winding connected to a two-wire line. Third and fourth partial windings having a grounded junction are coupled to a receiving branch and a transmitting branch of a four-wire transmission line, respectively. A power supply bridge having a resultant supply resistor and a supply capacitor is inserted between the first two partial windings. The total inductance of these windings equals the supply capacitor value times the squared supply resistor value. An ohmic load resistor terminating the receiving branch has a resistance according to a specific relationship depending on the ratio of turns of the third partial winding divided by those of the first and second partial windings. Finally, there is provided a quadripole network connected by a first input to the fourth partial winding, by a second input to the receiving branch; by a first output to the transmission line, and by a second output to ground. This network composed of a RC-network is designed such that signal portions of a signal received from the receiving branch of the transmission line supplied to the network directly and across the third and fourth partial windings in a phase-shifted condition are superimposed for cancellation.

Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To facilitate the control of a servo device when synchronous working is applied to a moving workpiece by means of a working machine that moves in parallel to the workpiece. SOLUTION: In this control method, the machining NC data NC2 are generated in regard to the axes X1 and X2 used for the 1st and 2nd moving members 2 and 5 which move a workpiece 3 and a working machine 6 toward the axes X1 and X2 set in parallel to each other respectively. Meanwhile, the moving NC data NC1 concerning the axes X3, Y and Z, i.e., the three orthogonal shafts of the machine 6 are programmed as conventional. The locus (velocity) data on each shaft are generated from both data C1 and NC2 and stored in the 1st and 2nd command duffers 51 and 52. Then the data stored in both buffers 51 and 52 are synthesized together in every servo cycle as the velocity data on the axes X1, X2' (X2+X3), Y and Z, stored in a register 53 and then distributed to the servo amplifiers 11 to 14 of axes X1, X2' Y and Z respectively.  Thus, it's possible to perform the control by means of a single NC controller 15A when the machine 6 performs the synchronous working to the moving workpiece 3.
