Patent number: 8005586Abstract: An electric golf cart that repeatedly travels around a given course of golf links is powered by a driving motor supplied with electric power from a driving battery. The electric golf cart is provided with a travel distance integrating unit, a memory, a battery charge and discharge integrating unit, and a discharge-per-course calculating unit. Mapping data is stored in the memory, which mapping data defines the relationship between the distance that the electric golf cart travels and the number of rounds that the electric golf cart has traveled. The number of rounds that the electric golf cart has traveled is calculated by the discharge-per-course calculating unit based on the travel distance obtained by the travel distance integrating unit along with the mapping data. Then, the number of rounds obtained and the discharge calculated by the battery charge and discharge integrating unit are utilized to identify the discharge of the driving battery per course.Type: GrantFiled: January 9, 2008Date of Patent: August 23, 2011Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Masayuki Miki, Satoshi Yamamoto

Patent number: 7880439Abstract: A battery-capacity management device comprises a charged/discharged-capacity integrating unit that detects a voltage and a current of a driving battery and that calculates a discharged capacity of the driving battery. The device also comprises a battery temperature sensor that detects a temperature of the driving battery, a memory, and an available-capacity calculating unit. Map data that represents relationships among voltages, currents, and temperatures of the driving battery at states in which remaining capacity of the driving battery has reached a preset value can be stored in the memory. The available-capacity calculating unit calculates a renewed available capacity of the driving battery based on a discharge capacity discharged over a period between a time when the driving battery is charged and a time when the voltage value detected by the charged/discharged-capacity integrating unit reaches a voltage value corresponding to the current value and the battery temperature in the map data.Type: GrantFiled: January 9, 2008Date of Patent: February 1, 2011Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Masayuki Miki, Satoshi Yamamoto

Patent number: 7359506Abstract: Inclined plane is provided at the tip of rotor cam. On the other hand, inclined planes are also provided in specific positions of stator cam. Because of this structure, in the specific positions, the inclined planes are in resilient contact with each other. Thus, the load is increased only in the specific positions without an increase in the load of spring. This structure can provide an opening and closing device capable of securely holding only desired positions without affecting the feel of opening and closing operation of the entire device, and electronic equipment using the device.Type: GrantFiled: February 10, 2004Date of Patent: April 15, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takehiko Konja, Yasuchika Kudo, Katsuichi Minami, Koji Sakai, Katsumasa Yamaguchi, Masayuki Miki, Naomasa Suzuki

Patent number: 6566742Abstract: An acceleration sensor is disclosed which includes a capacitance-type acceleration detection element mounted on a ceramic base plate. The element comprises a movable electrode mounted between a pair of fixed electrodes. Acceleration of the sensor in a measurement direction causes the movable electrode to move relative to the fixed electrodes and the element has opposite ends in a direction perpendicular to the measurement direction. The acceleration detection element is mounted on the base at a first one of the opposite ends. Accordingly, the mounting surface of the acceleration sensor is parallel to the direction of acceleration to be detected. Thus the acceleration sensor can be surface-mounted on a printed board, and more be easily mounted in an automobile air bag control system or the like.Type: GrantFiled: November 28, 2000Date of Patent: May 20, 2003Assignee: Hitachi, Ltd.Inventors: Masahiro Matsumoto, Seikou Suzuki, Masayuki Miki
