Patent number: 11909348Abstract: A stepping motor control device is provided, which controls a stepping motor including a rotor position detector by micro-step driving. The control device has a plurality of operation modes including an adjustment mode and a use mode. In the adjustment mode, the control device generates control data for a closed loop control for controlling the winding current of the stepping motor based on the detection value of the rotor position detector, and performs a stepping motor acceleration operation and a stepping motor deceleration operation according to the control data. In the use mode, the control device performs the stepping motor acceleration operation and the stepping motor deceleration operation so that a winding current observed in the adjustment mode is reproduced by an open loop control for controlling the winding current of the stepping motor based on the control data generated in the adjustment mode.Type: GrantFiled: March 2, 2021Date of Patent: February 20, 2024Assignee: ORIENTAL MOTOR CO., LTD.Inventors: Masayuki Someya, Akihiko Houda

Patent number: 9379598Abstract: The present invention provides an absolute encoder device, including: a permanent magnet including a first magnetic pattern (bipolar) and a second magnetic pattern (multipolar); a first magnetic sensor for detecting a magnetic field of the first magnetic pattern; a second magnetic sensor for detecting a magnetic field of the second magnetic pattern; and a signal processing circuit for calculating an absolute rotation angle of a rotation shaft based on output signals of the first and second magnetic sensors. The first and second magnetic sensors and the signal processing circuit are fixed to a single substrate. The first magnetic pattern is formed on a plane extending in a direction crossing an axial direction inside the permanent magnet, and the second magnetic pattern is formed on an outer peripheral surface of the permanent magnet.Type: GrantFiled: March 19, 2012Date of Patent: June 28, 2016Assignee: Oriental Motor Co., Ltd.Inventors: Masayuki Someya, Yoshio Hirasawa, Sakao Ozeki

Patent number: 8496129Abstract: Provided are a cap capable of being easily and reliably opened and unsealed not limited in design even if an inner cap with a small diameter is used for the cap, producing no refuse after the unsealing, and not unnecessarily large in size, and a container with the cap. When an over cap (3) is rotated in the opening direction, a pair of screw threads (10a, 10b) as opening means are advanced in the direction in which they are tightened together, and this cuts off a planned opening section (4) from the inner cap (2). Thus, the cap has a relatively simple structure and can be simply and reliably unsealed by small force. Also, the planned opening section (4) is integrated with the over cap (3) after unsealing the inner cap (2), so that no refuse is produced after the unsealing, eliminating the need to clear it away from a table.Type: GrantFiled: July 25, 2012Date of Patent: July 30, 2013Assignee: Tokan Kogyo Co, Ltd.Inventors: Takamitsu Isogai, Masayuki Someya

Thus, the cap has a relatively simple structure and can be simply and reliably unsealed by small force. Further, it is enough if the screw threads (10a, 10b) can be formed in the region of the opening, so that the structure can be applied to a cap with an inner cap with a small diameter and the design of the cap (1) is not limited.Type: GrantFiled: April 27, 2007Date of Patent: August 7, 2012Assignee: Tokan Kogyo Co., Ltd.Inventors: Takamitsu Isogai, Masayuki Someya

Patent number: 6384563Abstract: The load torque applied to the shaft of a synchronous motor is estimated based upon a correlation established between load torque and a calculated integral of a drive current value, utilizing the measured current that is applied to drive the motor. The estimated load torque is used as the basis for controlling the driving current amplitude so as to achieve increased efficiency of energy utilization. Control apparatus embodies the technique, and a synchronous motor system includes such apparatus.Type: GrantFiled: October 23, 2000Date of Patent: May 7, 2002Assignee: Seiberco IncorporatedInventor: Masayuki Someya

Patent number: 6150788Abstract: The voltage at a node between a pair of series-connected windings of a synchronous or stepping motor is monitored during operation so as to detect transition voltage regions, the durations of which are indicative of the torque load on the motor and which are used as the basis for controlling the driving current amplitude so as to achieve enhanced efficiency of energy utilization. An optimum value for the duration of the transition voltage region will usually be established as a target, and adjustments will be so made as to conform subsequently detected node voltage values to those of the target.Type: GrantFiled: February 16, 1999Date of Patent: November 21, 2000Assignee: Seiberco IncorporatedInventor: Masayuki Someya
