  • Patent number: 9021405
    Abstract: A plurality of gate electrode patterns to be laid out in parallel are alternately set as first patterns to be formed in a first exposure step of double patterning and as second patterns to be formed in a second exposure step. Subsequently, a circuit that includes transistor pairs each formed by connecting one of the first patterns and one of the second patterns in parallel is laid out. This reduces the risk of variations in characteristics of transistors caused by double patterning.

  • Patent number: 7458276
    Abstract: A magnetostrictive load sensor includes an upper casing, a lower casing, a coil, and a bobbin. The upper casing having an approximate bell shape has an upper end that is provided with an opening and a lower end that is provided with a notch. The lower casing includes a disk-shaped member and a bar-shaped member that are integral with each other. The coil is formed by winding a conducting wire around the bobbin. A predetermined position of the bobbin is provided with a lead wire outlet for taking out the conducting wire of the coil. A method of manufacturing the magnetostrictive load sensor includes inserting the bar-shaped member into the axial center of the bobbin, and covering the lower casing with the upper casing. In this way, the notch of the upper casing and the lead wire outlet of the bobbin are fitted with each other. An upper end of the bar-shaped member projects through the opening of the upper casing.

  • Patent number: 7430466
    Abstract: A watercraft has steering force detection sections. Each steering force detection section includes a pressure receiving section. The pressure receiving sections are spaced from each other and are in the vicinity of a steering shaft. A pressing member is coupled to the steering shaft. The pressing member can press on at least one of the pressure receiving sections when the steering handlebars are rotated to a maximum steering angle. A received pressure detection section detects the pressure applied to the pressure receiving section. The pressure receiving section and the received pressure detection section are coaxially mounted in a pressure receiving section casing and a detection section casing. A guide tube can engage the pressure receiving section and the received pressure detection section. The guide tube is formed with ribs and grooves. The pressure receiving section has a pressure receiving member, a bolt, a plain washer, and a spring member.

  • Patent number: 7381106
    Abstract: A steering assist system for a watercraft including a force detection assembly adapted to detect a force further applied to an operator steering control of the watercraft after the steering control is turned to a maximum turning position. The steering assist system also includes a controller configured to increase a steering force produced by the watercraft in response to an output of the force detection assembly. In one arrangement, the steering assist system increases an output of a propulsion system of the watercraft in proportion to an output of the force detection assembly. In another arrangement, the steering assist system moves a steering force producing member, such as a deflector or rudder, for example, in response to an output of the force detection assembly in addition to, or alternative to, increasing an output of the propulsion system.

  • Patent number: 7337739
    Abstract: Steering-force detection sections, including a pressure-receiving section and a received-pressure detection section, are spaced from one another in the vicinity of a steering shaft. The steering shaft can include a pressing member for applying pressure to the pressure-receiving section when steering handlebars are rotated in either direction to the maximum steering angle. The pressure-receiving section and the received-pressure detection section are coaxially mounted in a pressure-receiving section casing and a detection section casing, respectively, through a guide tube, so that the pressure-receiving directions of both the pressure-receiving sections are parallel to one another and perpendicular to the direction in which the steering-force detection sections are spaced. The detection section casing includes mounting openings for mounting the received-pressure detecting sections and an electric circuit board, which is integrally connected to the received-pressure detecting sections.

  • Patent number: 7320251
    Abstract: A load detector is constructed so as to stabilize an output voltage responding to an input load. The load detector includes a magnetostrictive sensor which includes a hollow case, a coil housed in the case, and a rod-like magnetic member located at an axial center of the coil, magnetized by an electric current flowing through the coil and receiving a load at an end thereof. The load detector further includes a pin which has a contact surface for applying the load onto the end of the magnetic member and is disposed axially inline with the magnetic member, and a bearing collar for reducing displacement of the pin with respect to the magnetic member. The magnetostrictive sensor and the pin are fitted, facing each other, into the bearing collar. The load detector is utilized suitably for transport equipment such as a water vehicle or electric bicycle.

  • Publication number: 20070113210
    Abstract: In gates, a gate length is same as that of an isolated Poly on a layout, however, is different from that of the isolated Poly on an actual silicon wafer. When the distance between the gates that is spacing between the gate becomes larger to some degree, the proximity effect is lost and the proximity Poly becomes same as the isolated Poly. In this way, because the correlation with another macro-cell arranged adjacent differs when the distance between the gates differs, the correlation coefficient varies. Therefore, correlation is grouped according to the distance between the gates.
