  • Patent number: 10317860
    Abstract: A monitoring control device includes a plug-in management unit that dynamically loads a plug-in made up of a plurality of actions, and that calls a predefined common function, declared in a program of the plug-in, in order to control the execution of an action stored in the plug-in, and extend a function of the monitoring control system, and an action-parameter management unit that holds arrays, in each of which an action parameter is stored, that is a parameter needed for an individual action included in the plug-in, by the number of actions described in a job file, and that designates an identifier and an element index of the arrays in order to read or write a value of the action parameter.

  • Patent number: 8118328
    Abstract: A power steering device for a vehicle includes an input shaft (1) linked to a steering wheel, an output shaft (2) linked to a vehicle wheel, a torsion bar (3) that connects the input shaft (1) to the output shaft (2), and a cylindrical member (13) supported by a housing (12) that is fastened to a vehicle body. The input shaft (1) includes a first input shaft (4) that is inserted into the cylindrical member (13), supported rotatably by the cylindrical member (13), and linked to the steering wheel, and a second input shaft (5) that connects the first input shaft (4) to the torsion bar (3). A connection portion between the first input shaft (4) and the second input shaft (5) is constituted such that a rotation of the first input shaft (4) is transmitted to the second input shaft (5) and the first input shaft (4) is free to move in an axial direction relative to the second input shaft (5).

  • Patent number: 6398242
    Abstract: A forklift has a frame and a rear axle, which is pivotally joined to the frame about a center pivot axis. Front and rear supporting members support the frame on the axle. A damper is located between the frame and the axle. The damper has an upper end connected to the frame and a lower end connected to the axle. A bracket for joining the upper end of the damper to the frame is located no further forward than the front end of the front support member and no further rearward than the rear support member. This structure suppresses torsion and bending force applied to the damper.

  • Patent number: 6203027
    Abstract: A structure for supporting a hydraulic cylinder that controls pivoting of a rear axle in a forklift. The rear axle is supported pivotally to the body. The hydraulic cylinder connects the rear axle to the body. Two hydraulic oil chambers are defined in the hydraulic cylinder. Movement of hydraulic oil between the oil chambers is selectively permitted and prohibited to selectively permit and prohibit pivoting of the rear axle. The body includes a pair of side frame members located on the sides of the body and a pair of cross frame members connected to the side frame members. The rear axle is located under the cross frame members. One end of the hydraulic cylinder is pivotally connected to the cross frame members by an upper joint. An upper pin, which is part of the upper joint, is directly supported by the cross frame members. Accordingly, an exclusive bracket for coupling the hydraulic cylinder to the body is not necessary. This simplifies the structure for coupling the hydraulic cylinder to the body.

  • Patent number: 6075520
    Abstract: The improved small current detector circuit and locator device each include a first and a second capacitor, a pulse drive circuit which drives one terminal of each capacitor by a pulse signal and charges and discharges the capacitors in synchronism with the rise and fall of the applied pulse so as to generate a first and a second detection signal at the other terminal of each capacitor. A current generator circuit receives the first and second detection signals and generates a current representing the difference between the levels of said signals. An integrator circuit integrates the output current from the current generator circuit. At least one of the first capacitor or second capacitor is provided in a detection portion of the detector circuit or locator device.
