A hydraulic forceps system includes: robotic forceps including: a gripper, first piston coupled to the gripper, first cylinder forming first pressure chamber, filled with a hydraulic fluid, together with the first piston, second piston, second cylinder forming a second pressure chamber, filled with hydraulic fluid, together with the second piston, communication passage through which the chambers communicate, motor that drives the second piston via a linear motion mechanism; control device that controls the motor based on a command position for the first piston; and position sensor used for detecting a position of the second piston. The control device includes: an observer that derives an estimated position of the first piston based on the position of the second detected by the sensor; and a position controller that derives a target rotational speed of the motor based on a deviation between the estimated position of the first piston and the command position.

Hydraulic forceps system

An object to reduce a relief amount at the start of turning. A hydraulic drive system of a construction machine includes: a turning control valve disposed on a first circulation line extending from a first pump; a boom control valve disposed on a second circulation line extending from a second pump; first and second regulators, which change tilting angles of the first and second pumps; and a controller, which controls one or more solenoid proportional valves, which output a secondary pressure to the first and second regulators. While a turning operation is being performed, if a discharge pressure of the first pump is higher than a first setting value and a discharge pressure of the second pump is lower than a second setting value, the controller lowers first and second horsepower control lines that restrict discharge flow rates of the first and second pumps.

An adaptive control device and adaptive control method, and a control device of an injection molding machine, which allow optimal adaptive control to be performed automatically and easily, while preventing a degradation of responsiveness. The adaptive control device is configured to perform feedback control in such a manner that an operation value is output based on a command value and a feedback value which is a sum of a controlled value output from a controlled target and a compensation value output from a parallel feed-forward compensator; wherein the parallel feed-forward compensator includes: an identification section which sequentially estimates a frequency response characteristic of the controlled target and an adjustment section which adjusts the compensation value based on the estimated frequency response characteristic.

A golf clubincludes a shaft, a tip member provided at a tip part of the shaft, and a rear end member attached to a rear end part of the shaft. The tip member includes a head. The rear end member includes a gripand a weight member. The golf club has a club length of 1143 mm or more. A value of [W2/W1] is no less than 0.23 and no more than 0.32 when a weight of the tip member is W1 (g) and a weight of the rear end member is W2 (g). The weight memberis provided on a rear side relative to a tip position of the grip. The weight memberhas a specific gravity larger than that of the shaft. The golf clubis a wood type golf club. Examples of materials for the weight memberinclude brass, a tungsten nickel alloy, an aluminum alloy, a tungsten alloy, a stainless alloy, stainless steel, and the like.

A method for producing a tubular body includes a step of winding at least one of winding bias prepregs, at least one of straight prepregs, and at least one of hoop prepregs round a core. At the winding step, after the hoop prepreg and/or the hoop prepreg are adherently layered in advance on a base prepreg consisting of the bias prepreg or the straight prepreg to form a laminate and/or a laminate, the laminate and/or the laminate are wound on the core so that the hoop prepreg and/or the hoop prepreg are wound on the core integrally with the base prepreg or the base prepreg.

In a reference section (D), an intersection point of a line which passes through a center of gravity (g) of a head and is perpendicular to a horizontal plane (H) and a sole surface () is represented by (T), a line passing through the point (T) and a leading edge point (Le) is represented by (S), a point which is present on the sole surface () and is provided apart from the line (S) toward a lowermost side is represented by (T), a line which passes through the point (T) and is parallel with the line (S) is represented by (S), a distance between the point (T) and the line (S) is represented by (K), a line passing through the point (T) and the point (Le) is represented by (S), a distance in the front-rear direction between the point (T) and the point (Le) is represented by (L), and a distance in the front-rear direction between the point (T) and the point (Le) is represented by (M). An angle (&#x3b8;) formed by the line (S) and the horizontal plane (H) is equal to or greater than two degrees and is equal to or smaller than ten degrees. (K/M) is greater than zero and is equal to or smaller than 0.10. (L/P) is equal to or greater than 0.10 and is equal to or smaller than 0.50. A lower portion () positioned below the line (S) is present between the point (T) and the point (Le).

Golf putter

A movable object maneuver method wherein a destination point is set; wherein a thrust value is calculated in real time which minimizes or maximizes a performance index associated with one or more state variables and thrust required for a movable object to reach the destination point and which takes into account non-linear conditions inherent to the movable object; and wherein the movable object is moved based on the calculated thrust value.
