Title: Controller for sr motor driven by square wave
Inventor: ASO TAKESHI
IPC: H02P25/08
Filed: 1993-08-06
Abstract: PURPOSE:To stably decide a control command excellent in drive efficiency, in a controller for an SR motor driven by square waves. CONSTITUTION:An angle detection sensor 2 as a means for detecting the rotational angle of a rotor is attached to an SR motor 1 driven by square waves, and the angle signal from the angle sensor is inputted into a controller 3 together with the torque command signal from a torque command generator 4. The controller decides energization commands such as energization width, energization start angle, etc., with power source voltage as energization voltage without applying PWM in a great part of revolution range, based on those signals, and also widens the energization width, setting the energization voltage in low condition in advance in low revolution range. A power head driver 5 is operated by the output device inside the controller, according to the decided energization command value so as to drive a motor. Hereby, the switching loss of the power element inside a driver is reduced, and such effect that desired torque can be generated under high efficiency can be obtained.

Title: Standard sample for ultrasonic flaw detection test for evaluating fine flaw
Inventor: NURI YOSHIO
IPC: G01N29/22
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To obtain a standard sample usable when a nonmetal enclosure in steel or a flaw having a size equal to that of it is accurately and quantitatively evaluated from the intensity of a reflected wave by embedding one or more oxide or metal particle with a particle size of a specific value or less and/or one or more metal wire with a wire diameter of a specific value or less in a synthetic resin. SOLUTION: As a standard sample for an ultrasonic wave flaw detection test, for example, an alumina particle with a particle size of 100 μm or less as an oxide particle to be embedded, a metal particle having the same particle size as that of the oxide particle as a metal particle to be embedded or a stainless steel wire having the same diameter as that of the oxide particle as a metal wire to be embedded is used. If this sample is embedded in a transparent resin, the distance between a flaw detection surface and this artificial flaw can be recognized from an outer surface and the distance between them can be arbitrarily controlled by grinding processing or polishing processing after formation.  By using the oxide or metal particle with a particle size of 100 μm or less or the metal wire with a wire diameter of 100 μm or less, a nonmetal enclosure or a flaw having a size equal to that of it in steel can be quantitatively evaluated.

Filed: 1981-12-25
Abstract: PURPOSE:To change over the reception mode at the reception side automatically by the control at the transmission side, by transmitting a switcing code and a substituting code from the transmission side, and detecting the switching code at the reception side. CONSTITUTION:In switcing sound into data at the transmission side, after the transmission of a digital voice signal, a selector 4 is changed over and a switching code 8-bit at the output of a switching code generating circuit 3 is transmitted and a signal from a data input terminal 5 is transmitted by switching the  selector 4.

Thus, the reception input after the operation including  the switching code is not decoded. Further, through the input to the data output  gate control terminal 103, the data output gate 10 outputs the data mode, and  the reception input after this operation is outputted to the output terminal 102.

Title: Switching method without short break for atm transmission line and its circuit
Inventor: NAKANO YUKIO
IPC: H04L69/40
Filed: 1990-08-17
Abstract: PURPOSE:To switch an ATM transmission line to an instaneous interruption with the processing at a reception side only by allowing the reception side to control a delay so that the content of a valid cell of an active transmission line and a valid cell of a standby transmission line is made coincident with each other. CONSTITUTION:Active cell buffers 41, 43 select only a valid cell in ATM cells sent from an active reception circuit 21, stores and delays it for a specific time. Similarly, standby cell buffers 42, 44 select only a valid cell in ATM cells sent from a standby reception circuit 22, stores and delays it for a specific time. Cell coincidence detection circuits 51-55 compare the content of the valid cell of the active reception signal with the content of the valid cell of the standby reception signal, revise the difference of the valid cells of the active reception signal and the standby reception signal so as to make the content coincident when the discordance of the contents is detected consecutively for a specific cell number or above. Then a system selective circuit 57 selects one of an output ATM cell of the active cell buffer and that of the standby cell buffer. Since no transmission/reception of control is required with a transmission side, instaneous interruption switching is attained also with respect to the reception signal of any kind of equipment.
