摘要： ABSTRACT There is provided a packaging apparatus including a mechanism for joining a film from a film roll and a film from another film roll to each other. The packaging apparatus is capable of preventing a joint of the films from suffering a thermal sealing failure thereby increasing production efficiency. Package apparatus (10) includes film supply mechanism (10A) for joining and supplying films (1A, 1B) and packaging mechanism (10C) for producing package bags from the film. Film accumulator (10B) for guiding and holding the film in a meandering fashion is disposed between film supply mechanism (10A) and packaging mechanism (10C). Some of accumulating rollers (21) of film accumulator (10B) are movable to a predetermined position depending on the size of package bags to be manufactured. The length of the film from a position in which the films are joined to each other to a position in which the film is horizontally sealed is changed to prevent the joint between the films from being placed in the position in which the film is horizontally sealed.

摘要： A position detector includes a fluid cylinder having a piston. An ultrasonic transceiver is provided at one end of the piston outside of the moving range of the piston. In response to electrical signals, the ultrasonic transceiver transmits ultrasonic waves to a reflection surface of the piston. The transceiver receives the ultrasonic waves reflected by the piston and then generates electrical signals representing the reflected waves. A sensor detects that the piston is at a predetermined position, at which the distance to the transceiver is known. A CPU supplies electrical signals to the ultrasonic transceiver to produce ultrasonic waves and receives electrical signals representing the reflected waves from the ultrasonic transceiver. The CPU then computes a piston position value, which is a function of the travel time from when an ultrasonic wave is transmitted to when the reflected wave is received and the speed of the waves. The CPU determines the speed of the waves when the piston is detected to be at the reference position. The CPU then computes the current position of the piston based on the speed of the waves and on a current reading of the travel time.

摘要： An industrial vehicle has a loading attachment, a mast, a tilt cylinder, first and second pressure sensors and a controller. The mast supports the attachment and guides the attachment. The tilt cylinder has a piston and a piston rod and operates by hydraulic fluid from a hydraulic fluid source. The piston rod connects with the piston and also connects with the mast. The piston divides the inside of the tilt cylinder into a rod side chamber and a bottom side chamber. The first and second pressure sensors respectively detect pressures of the hydraulic fluid in the rod side and the bottom side chambers. The controller calculates an axial force applied to the tilt cylinder based on signals detected by the sensors and calculates load weight moment in a back and forth direction of the vehicle based on the axial force and compares the calculated moment with a predetermined value.

摘要： A pressure sensor is set in a conduit connected to a cylinder tube, and a temperature sensor is disposed within a chamber. Detection signals of the pressure sensor and the temperature sensor are sent to a control circuit. A sonic speed of the ultrasonic wave is corrected by using a relational formula or a map that is indicative of the relationship of the temperature and pressure of hydraulic oil to the sonic speed and that is stored in the storage device. A distance from an ultrasonic wave sensor to a bottom surface of the piston is calculated based on the sonic speed and a measurement time length detected by the ultrasonic wave sensor.

摘要： An ultrasonic sensor is located in the bottom of a lift cylinder of a forklift and emits ultrasonic waves toward a piston in the cylinder. A controller controls the ultrasonic sensor to consecutively emit ultrasonic waves that have different amplitudes at predetermined intervals. The ultrasonic waves are emitted in order of smallness of amplitude. The controller computes the distance between the ultrasonic sensor and the piston based on a period from when the ultrasonic sensor emits one of the ultrasonic waves to when the ultrasonic sensor receives the ultrasonic wave that is reflected by the piston. As a result, the range of the detectable distances is extended.

摘要： A controller for a hydraulic fluid flow control apparatus determines a quantity necessary for loading/unloading operations according to a signal from a lever operating degree detector, and controls a variable displacement type hydraulic pump to obtain the quantity. Accordingly, unnecessary hydraulic fluid flow in the hydraulic apparatus is reduced. The controller determines when a vehicle is stopped according to a signal from a clutch ON-OFF detector or a neutral sensor, and can raise the rpm of an engine. Therefore, when the loading/unloading operations are being executed while the vehicle is stopped, there is no need to operate the accelerator pedal.
