摘要： PURPOSE:To perform a job for safety conveyance by keeping off any running back of equipment which conveys a work or material in a lifting grade interval of rail traveling linear type suspended conveyor facilities. CONSTITUTION:In a rail traveling linear type suspended conveyor which conveys an apparatus being hung from a traveler traveling on a rail by driving it by means of an interaction in a linear motor, a link chain 81 is installed in a travel rail 3 extendedly along the traveling longitudinal direction of the apparatus 10, while a sprocket wheel 66 in mesh with this link chain 81 is pivoted to the traveler 20 via a clutch means which allows only the one-way rotation of the sprocket wheel 66, checking another directional rotation with a one-way clutch. With this one-way clutch, any running back of the suspended conveyor is prevented from occurring.

摘要： PURPOSE:To definitely prevent the smooth movement from being disturbed by controlling an inverter in such a manner that the voltage phase and frequency of a stator winding in the last stage section will coincide with those of a stator winding in the first stage section when a moving member shifts from the first stage to the last stage. CONSTITUTION:A runway is divided in the moving direction of a moving member 1, and each subdivision is equipped with an independent stator winding 2a, 2b, 2c respectively. The stator windings 2a to 2c are driven by inverters 3a to 3c being frequency-controlled independently. Each inverter 3a to 3c is controlled in such a manner that the voltage phase and frequency of each stator winding 2a to 2c in the last stage section will become the same as those in the first stage section when the moving member passes the boundary between the neighboring sections.

摘要： PURPOSE:To carry out safety conveyance while keeping off any scamper or runback of equipment at the time of conveyance at a grade interval by performing frictional braking in a way of holding a brake shoe, under pressure, in cooperation with a depressor rail and a braking rail at the time of braking a conveyor. CONSTITUTION:A braking rail 81 is installed tight along a traveling rail 3, and a depressor rail 82 made liftably movable up and down along the traveling rail 3 is additionally installed therein. Then, an braking arm 61 fitted with a brake shoe 62 is pivoted to the side of a traveler 20, and this brake shoe 62 is equilibriously supported in keeping a void in space between the traveling rail 81 and the depressor rail 82 usually. When braking of a conveyor 10 is performed, frictional braking takes place in holding the brake shoe 62, under pressure, in cooperation with the depressor rail 82 and the braking rail 81. Thus, even in the case where the conveyor 10 is stopped in the point midway in the grade interval or accidentally stopped, a scamper or running-back is made precentable from occurring.

摘要： PROBLEM TO BE SOLVED: To obtain a measuring method and a measuring apparatus, which use a photocurrent sensor capable of precisely measuring the difference between the inflow current and the outflow current of a power facility, as an object to be protected, even in a region in which an electrification current is a large current. SOLUTION: A first photocurrent sensor 2 is installed, so as to measure an inflow current i1, and second photocurrent sensor 3 is installed to measure an outflow current i2. A signal processing means 1 comprises a light-emitting means 12, a light-receiving means 16, an AC-signal detection means 17, a DC-signal detection means 18, a division means 19 and a power-supply frequency-component detection means 20. The light- emitting means 12 and the first photocurrent sensor 2, the first photocurrent sensor 2 and the second photocurrent sensor 3 and the second photocurrent sensor 3 and the light-receiving means 16 are connected in series by respective light signal transmission means 4. Regarding a frequency component, which is twice that of the electrification current of a power facility contained in the signal of a difference current measured by the photocurrent sensors, the frequency component which is the same as the energizing current is taken out, and an output which is proportional to the difference current i1-i2 is obtained.

摘要： PURPOSE:To stabilize switching work, by adding a control circuit anew to a reference sinusoidal wave generation circuit. CONSTITUTION:The input section of the second PT 111 is connected to a preliminary output power source 105, whose output section is connected to an A/D converter 116 on one hand, and on the other it is connected to a reference sinusoidal wave generation circuit 113. The output of the A/D converter 116 is connected to the above-mentioned generation circuit 113 so as to be stored to an external memory 119 as a digital signal with a microprocessor unit 118 (MPU). On the other hand, the output voltage waveform on an inverter circuit side is inputted from an AC filter circuit 104 of an inverter device to the generation circuit 113 through the first PT 107. Eddy current will thereby be generated to the output current of the inverter device. When the preliminary output power source 105 becomes feeding condition, the voltage waveform is converted into a digital signal by the A/D converter 116 and is stored to the external memory 119. Then, this is converted into an analogue signal with the above-mentioned generation circuit 113 and is controlled so as to synchronize the output voltage phase.
