The antagonistic strain Bacillus amyloliquefaciens strain S13-3 decreased the severity of strawberry anthracnose caused by Colletotrichum gloeosporioides. The foliar application of S13-3 triggered the expression of pathogenesis-related proteins, chitinase and β-1,3-glucanase, in strawberry leaves. We identified lipopeptide antibiotics, including iturin A, fengycin, mixirin, pumilacidin and surfactin, produced and secreted by S13-3. Iturin A and surfactin elicited the gene expression of the pathogenesis-related proteins in strawberry leaves, suggesting that antagonistic strain S13-3 confers resistance to strawberry leaves through the production of lipopeptide antibiotics. In fact, iturin A and surfactin triggered induced systemic resistance on strawberry plants, resulting in the reduction of the severity of anthracnose disease caused by Colletotrichum gloeosporioides. The bifunctional activity of S13-3, which consists of the antagonistic effect and the induction of plant defence response by the antibiotics produced by it, may make S13-3 an innovative biological control agent against phytopathogens in strawberry. © 2014 The Society for Applied Microbiology.

The purpose of the present invention is to provide an actuator such that egress of a lubricant to the outside of a housing during forward and rearward movement of a rod is prevented. The actuator comprises: a housing having a rod through-hole; a rod which passes through the rod through-hole such that a portion thereof protrudes to the outside of the housing and is driven forward and rearward; a first rod sealing member which is arranged near the outside of the housing in the rod through-hole; a second rod sealing member arranged near the inside of the housing in the rod through-hole; a lubricant supply part provided in the housing and supplying lubricant to the rod through-hole; and a pressure change absorption groove which is provided between the first rod sealing member and the second rod sealing member in the rod through-hole to communicate with the lubricant supply part, and forms an air layer while absorbing the pressure changes associated with the forward and rearward movement of the rod.

A motor control apparatus includes a high-resolution encoder for position control and a low-resolution encoder for velocity control, position control means for generating a velocity command in accordance with a difference between a given position command and the output of the high-resolution encoder, and velocity control means for generating a current command in accordance with a difference between the velocity command and a detected velocity that is based upon the output of the low-resolution encoder. A velocity control cycle based upon the velocity control means is made faster than a position control cycle based upon the position control means.

An actuator comprises: a housing which is provided with an opening; a slider which is installed so as to be movable relative to the housing; a drive means which is installed in the housing and which moves the slider; at least a pair of seal members which is disposed at the opening of the housing so as to face each other and which exhibits dust-proof and drip-proof functions by engaging with each other; and move-through members which are mounted to both sides of the slider in the movement direction thereof and which move through the pair of seal members. The move-through members each comprise: a move-through section which pushes apart the pair of seal members in the direction in which the pair is separated; a cover section which covers an expanded opening formed between the pair of seal members when the pair is pushed apart by the move-through section; and an opening restriction section which, when the pair of seal members is pushed apart from each other by the move-through section, restricts the amount of opening between the pair of seal members and in turn restricts the size of the expanded opening.


The purpose of the present invention is to detect the absolute rotation angle of a rotor in a simple manner. In order to detect the rotation angle of a rotor of a stepping motor including a rotor and a stator winding, a first magnetic sensor (151) having a resolution of 200 steps per mechanical angle of 360 degrees detects the rotation angle of a rotor. An incremental encoder (60) outputs a plurality of types of signals periodically in accordance with the rotation angle of the rotor. A rotation angle acquirer (122) in a controller (102) acquires the absolute rotation angle of the rotor on the basis of the rotor rotation angle detected by the first magnetic sensor (151) and the type of signal output by the incremental encoder (60).

An actuator (10) includes a guide apparatus (30) that guides a rod 11 in a Y-axis direction. The guide apparatus (30) includes a slider (31), a rail (60) formed of a steel material, and balls (rolling elements) formed of a steel material. The slider (31) is supported by the rail (60) through the balls. Accordingly, even if torque originating from a rotation of the output shaft of a motor unit (20) is applied to the slider (31) through a ball screw shaft (71), the slider (31) does not move around the output shaft with respect to the rail (60). Hence, torque originating from the rotation of the output shaft is not likely to be transmitted to the rod (11) through the guide apparatus 30, thereby suppressing an occurrence of the wobbling of the leading end of the rod (11). In addition, a reduction of the work precision of the actuator (10) is preventable.
