摘要： PROBLEM TO BE SOLVED: To assure reliability and realize low cost even in such radiowave environment that radiowave interference is easy to occur.
SOLUTION: Channels to be used are so set as to be distributed not to overlap other ones, so that correspondence is made between a data transmission side and a reception side. On the data transmission side, carrier sensing is performed in parallel via radio communication circuits 5a-5d when a transmission request for data occurs. Data is transmitted by allocating it to a first channel with its preset priority on a high order side and its noise level at a predetermined level or lower. On the data reception side, the data transmitted from the transmission side is received for processing, by any one of the radio communication circuits 5a-5d.

摘要： PROBLEM TO BE SOLVED: To eliminate the need for using a ball screw and a ball nut and to inexpensively configure an electro-hydraulic servo cylinder in the electro- hydraulic servo cylinder having a valve structure for switching an oil channel inside a piston.
SOLUTION: A spool 43 having a switching groove where a spiral valve switching mechanism 49 is formed at an outer periphery section is arranged inside the piston 32. When the spool 43 is rotated by an electric motor 46, and the valve-switching groove 49 communicates with a port 38 for pressure oil, the pressure oil in a rod-side fluid chamber 33a is introduced into a head side fluid chamber 33b, and the piston 32 advances toward an arrow A1. When the valve-switching groove 49 communicates with a port 39 for drain oil, the head side fluid chamber 33b communicates with a drain oil port 71 and pressure decreases for causing the piston 32 to retreat. In this case, it is not necessary to use the ball screw and the ball nut.

摘要： PURPOSE:To widen a measuring speed region and improve revolving power by detecting rotating speeds in accordance with the time differentiation of the phase deviation of the rotation detecting signal with respect to a reference AC signal in a tachometer. CONSTITUTION:primary windings 2A and 2C as well as 2B and 2D are wound respectively differentially on the exiciting poles A-D of a stator 1, and are excited by the AC signals of phases shifting by 90 deg. each other from oscillators 5, 6. A rotor 3 is mounted off from the center of a revolving shaft 4, and according to its rotating angle theta, the gaps from the respective excitating poles change, thereby causing a reluctance change for one period of trigonometric functions in one revolution. If the combined output of the induced voltages of the respective exciting poles is detected by the windings 7A and 7C which are mutually of in-phase and the secondary windings 7B and 7D which are of anti-phase from these, the signal deviated in phase by the rotating angle theta with respect to the AC signals for excitation is obtained. During revolution, the theta is a function of time, and from the time differentiation thereof, the speed is determined.
