摘要： PURPOSE:To instantaneously grasp the present position of a servomotor at recovery of a power failure even if the power failure occurs during the control by detecting the present position of the servomotor via an absolute position detector. CONSTITUTION:A target position of a servomotor 42 is set by a target position setting means 21 in the form of the absolute value. While the speed characteristics are set by a speed setting means 20. An arithmetic means 25 produces a time function pattern for the absolute command position of the servomotor 42 up to the target position set by the means 21. The produced time function pattern is stored in a memory 24. Then a reading means 22 transmits the speed command data on the servomotor 42 based on the deviation between the absolute command position data read out of the memory 24 and the present position of the servomotor 42 detected by an absolute position detector 60.

摘要： PURPOSE:To inexpensively produce a long life laminated sheet excellent in rigidity and generating no corrosion, by applying a fiber reinforced thermoplastic resin member containing a long glass fiber to the single surface or both surfaces of plywood and heating said member to predetermined temp. to mold the same under pressure. CONSTITUTION:A sheet like fiber reinforced thermoplastic resin member FRTP 1 is preheated to about 200 deg.C to be brought to a semi-molten state and placed on the lower mold 11 of a mold 10. As a reinforcing fiber, a long glass fiber having an average fiber length of 1.0-100mm is used. Next, plywood is placed to the recessed part of the FRTP 1. The plywood 2 is slightly smaller than the FRTP 1 and formed by laminating veneers by an adhesive so as to cross grains each other at a right angle. Next, a sheet like FRTP 3 preheated to about 200 deg.C to be brought to a semi-molten state is placed on the plywood 2 and the upper mold 12 of the mold 10 is allowed to fall to integrally mold the lower FRTP 1, the plywood 2 and the upper FRTP 3. In this case, both upper and lower FRTP 1, 3 are arranged so that the directions of the long fibers contained in the FRTP 1, 3 are made different to to each other.

摘要： PURPOSE:To improve the responsibility and minute flow rate controllability of a servo valve by inserting valve members which are connected with the first and the second rotary driving body, and establish valve openings according to the relative rotating angles of both the said rotary driving bodies in a valve main body. CONSTITUTION:A valve member 1 which is connected with the first and the second motor M1, M2, and establishes a valve opening communicating with load ports C1-C4 according to the relative rotating angles of the said motors is inserted in a valve main body 3. Since the said relative rotating angles can be therefore controlled by adjusting the rotating angle of the said motors, the valve opening can be extremely smoothly and quickly adjusted to improve the responsibility of the valve. In addition to that, since the relative rotating angle is controlled by means of a time function, infinitesimally divided time in the said function can make the control of a minute flow rate possible.

摘要： PURPOSE:To enable a cutting edge to be prevented from its damage caused by being bitten with a chip, by positioning a ridgeline of each cutting edge in the more rear side to the more center side of a tap than the extension of a ridgeline of each cutting edge in the front side in a chamber of the tap. CONSTITUTION:Each cutting edge D1-D10 in a chamfer A is arranged such that a ridgeline I of the cutting edges > in the more rear side is positioned to the more center side of a tap than extensions K, L of a ridgeline I of the cutting edges > in the front side. Accordingly, even if a chamfer angle beta is set to, for instance, 24 deg., the chamfer A can be provided with the cutting edges D1-D10 in 2.5 threads, and if a complete thread part B is formed to provide 7.5 threads with a spiral angle alpha of 35 deg., a chip of larger pitch than usual is generated, causing a part of the chip turned 360 deg. after its generation to be discharged from the complete thread part B. In such way, damage of the cutting edge caused by being bitten with the chip can be eliminated.
摘要翻译：目的：为了防止由于被芯片咬住而引起的切削刃的损坏，通过将每个切削刃的棱线位于更靠后的一侧到比龙头的中心侧更靠中间的棱线前端的切割边在水龙头的一个室中。构成：倒角A中的每个切削刃D1-D10被布置成使得更靠后侧的切削刃“D5-D8和D9，D10”的棱线I位于比龙头更靠中心的一侧在前侧的切削刃<< D1-D4和D5-D8的棱线I的延伸部K，L。因此，即使倒角β被设定为例如24度，倒角A可以设置有2.5螺纹的切削刃D1-D10，如果形成完整的螺纹部B以提供7.5螺纹螺旋角α为35度，产生比通常更大间距的芯片，导致芯片的一部分转动360度。在其生成之后，从完整的螺纹部分B排出。这样，可以消除由于被芯片咬住而导致的切削刃的损坏。

摘要： PROBLEM TO BE SOLVED: To obtain good responsiveness and excellent detecting characteristics with a simple structure, and to achieve expansion of the object to be detected, improved detection reliability as well as improved reliability for life and easier maintenance. SOLUTION: A hollow ring-shaped sensor case 23 accommodating a toroidal coil 22 consists of a ring-shaped case 23A of conductive metal having an opening throughout the entire corner of its circumference and a ring-shaped rim part 23B of insulating material closing the opening, both made integral with each other. Under the sensor case 23, there is provided an electrode 25 through a spacer 24 of insulating material. When a tool 28 advances into a space W enclosed by the sensor case 23, coupling capacitance C between the electrode 25 and the tip of the tool 28 increases whereby a current flows passing the coil 22 through the capacitance C and the tool 28, which is detected by a signal processing circuit 27.

摘要： PROBLEM TO BE SOLVED: To make the effective use of existing appliances, without discarding them as well as improving reliability, when the driving source of a servo- cylinder mounted on a continuous casting machine is changed from a stepping motor into a synchronous servo motor, which is controlled in close-loop manner. SOLUTION: A motor driver 16 involves a current control part 18 for supplying respective phases of excitation currents to a five-phase stepping motor 12 and a four-phase servo motor 14, an open control part 21 for open-loop control of the stepping motor 12 and the servo motor 14, a position detecting part 19 which is needed for close-loop control of the servo motor 14, a close control part 20, and a switching control part 22 conducting a prescribed switching operation, according to the type of a motor connected to a terminal 17. The switching control part 22 switches to an open-loop control, when something abnormal occurs in a signal from a detector 15 with the servo motor 14 under a close-loop control.

摘要： PROBLEM TO BE SOLVED: To enable execution of a simple and safe exterior work of a building at a low cost without installing scaffolding, in a simple knockdown gondola suspension type work apparatus. SOLUTION: An arm 18 is supported by a support frame 22 at an intermediate section. The support frame 22 can be moved along a coping 28 of a concrete building by a roller 26. A gondola 14 is suspended from one end of the arm 18 with a suspension cable 16. A horizontal movement frame 38 is installed at the other end of the arm 18 and is provided with a water tank 36 as a weight. The horizontal movement frame 38, having the water tank 36, is located at a position away from the support frame 22 acting as a fulcrum by a distance y which is larger than distance x to the suspension point of the gondola. The weight of the water tank and the ratio of x/y are set, in such a manner as to make the moment of pushing the weight toward the top face of the building at least 2.5 times larger than the moment in the direction opposite to the former.

摘要： PROBLEM TO BE SOLVED: To reliably detect the step-out of a stepping motor which is used under high-temperature environment and in a very narrow space, by detecting the rotation of the stepping motor with a rotation detector of an absolute posi tion detecting type. SOLUTION: A rotation detector 30 for detecting an absolute position normally has a lead 39 extending from its body, and signals need to be transmitted up to a converter by connecting an extension cable 56 to the lead 39. Here, a heat-resistant lead 39 is connected to the heat-resistant extension cable 56 at a connection part 58 inside a casing 50. This is due to the fact that the lead 39 is not of specifications sufficiently durable to external environment but that it is required to be contained inside the casing 50. Also, the connection part 58 is completely sealed with a high-temperature resistant adhesive. This is for preventing the occurrence of insulation failures in the connection part 58, when vapor infiltrates to the inside of the casing 50.
