Publication number: 20190286238Abstract: A touch panel-equipped display device (100A) includes a display member (120), a light transmitting touch panel (130) arranged to overlap with the display member (120), a panel holder (140A) configured to support the display member (120), and an actuator (1) configured to transmit vibration in an in-plane direction of an input surface (115) to an input member (110) configuring the input surface (115) for the touch panel (130). The input member (110) is supported by the panel holder (140A) via a first elastic member (180A) having at least one of elasticity and viscoelasticity. Further, the actuator (1) is not connected to the panel holder (140A). Therefore, even if an operator strongly presses the input surface (151), the vibration of the actuator (1) can be properly transmitted to a fingertip of the operator.Type: ApplicationFiled: October 17, 2017Publication date: September 19, 2019Applicant: NIDEC SANKYO CORPORATIONInventors: Akihiro YAHATA, Tadashi TAKEDA, Hiroshi KITAHARA, Jinichi ITO

Patent number: 4977359Abstract: In a servo motor system, consisting of a servo motor unit, a servo driver unit, power transmission lines for supplying electric power from the servo driver unit to the servo motor unit, and signal transmission lines for supplying electric signals from the servo motor unit to the servo driver unit, to the end of reducing the number of the signal transmission lines without requiring any particularly high-speed or high-quality signal transmission lines, the servo motor unit comprises a parallel-serial signal conversion circuit for converting outputs from a pole sensor, a rotary encoder, and an abnormal condition sensor into a single serial signal which is transmitted to the servo driver unit via one of the signal transmission lines. The servo driver unit comprise a serial-parallel signal conversion circuit for separating from the serial signal the aforementioned outputs from the various sensors.Type: GrantFiled: November 24, 1989Date of Patent: December 11, 1990Assignees: Omron Tateisi Electronics Co., Kabushiki Kaisha Sankyo Seiki SeisakushoInventors: Kenji Sawai, Tuneto Takeuchi, Jinichi Ito

Patent number: 4658190Abstract: A drive circuit for a three-phase brushless motor in which two Hall detectors are spaced 120.degree. apart in electrical angle near the rotors to detect magnetic flux signals for two phases. Their outputs are summed and inverted to form the third phase signal. The three phase signals drive the respective coils on the stator. The three phase signals are also separately squared and then added to adjust, in a feedback fashion, the current through the Hall detectors, whereby torque ripple is reduced.Type: GrantFiled: October 26, 1984Date of Patent: April 14, 1987Assignee: Kabushiki Kaisha Sankyo Seiki SeisakushoInventors: Kiyoshi Miyazaki, Jinichi Ito, Hayato Naito

Patent number: 4403174Abstract: A commutatorless DC motor drive device in which errors due to offset voltages of differential amplifiers used therein are eliminated to thereby cause the rotor to rotate at a stable speed. Double-balance differential amplifier circuits are arranged to receive outputs of corresponding magnetic sensitive elements, such as HALL elements, upon differential input terminals thereof and external control signals upon differential control voltage terminals thereof. The outputs from the magnetic sensitive elements are amplified with an amplification factor determined by the control signals. The control signals have an amplitude determined in accordance with the rotational speed of the rotor. Output circuits control the amount of current fed to the stator coils in accordance with differential outputs of the double-balance differential amplifier circuits.Type: GrantFiled: August 17, 1981Date of Patent: September 6, 1983Assignee: Kabushiki Kaisha Sankyo Seiki SeiksakushoInventors: Kiyoshi Miyazaki, Jinichi Ito

Patent number: 4350937Abstract: A motor speed control device for a small DC motor in which the speed of rotation of the motor is maintained stable during ambient temperature changes and changes in the load applied to the motor. A temperature compensation resistor is coupled in series with a voltage divider circuit and the combination thereof coupled across the motor. A motor control circuit is provided having first through fourth control terminals. The first control terminal is coupled to the junction between the temperature compensation resistor and the voltage divider circuit, the second control terminal to the voltage division point, the third control terminal to the junction between the voltage divider circuit and the motor, and the fourth control terminal is coupled to ground. The motor control circuit includes an error detecting circuit having inputs coupled to the first and second control terminals with a voltage reference source coupled in series with the first input terminal to the error detecting circuit.Type: GrantFiled: August 1, 1980Date of Patent: September 21, 1982Assignee: Kabushiki Kaisha Sankyo Seiki SeisakushoInventors: Kiyoshi Miyazaki, Tsuneto Takeuchi, Jinichi Ito, Hiroo Ashibe

Patent number: 4011761Abstract: A wheel balancer comprising a pair of shafts for supporting a rotary shaft for rotatably mounting a wheel having an amount of unbalance to be measured is disclosed. The supporting shafts are located on a circle having a center which is coincided with a movable instantaneous center of vibration of the wheel and held by a pair of spring members such that the supporting shafts are movable in a direction of a tangent touching the above mentioned circle. The amount of unbalance of the wheel is converted into an electrical signal which is supplied through a calculation circuit to a comparison circuit which can detect the position of the instantaneous center of vibration by means of an indicating means movable in proportional to the amount of movement of the instantaneous center of vibration of the wheel.Type: GrantFiled: December 22, 1975Date of Patent: March 15, 1977Assignee: Yamada Yuki Seizo Co., Ltd.Inventor: Jinichi Ito
