Title: Robot actuator
Inventor: YAMAMOTO YOSHIO
IPC: B25J19/00
Filed: 1984-11-26
Abstract: PURPOSE:To drive a robot with high accuracy and to simplify the setting of a shape memory alloy wire by connecting a nut to said alloy wire via a wire connected with a shift given in the circumferential direction. CONSTITUTION:A robot consists of an arm storing an actuator, a wrist and a hand. The actuator is formed with plural shape memory alloy wires 22 stretched between terminals 20a of a pair of front and back terminal plates 20. These plates 20 are connected to plural stainless wires 26 and then to the wrist and the hand via a straight/revolution converting mechanism 28 set within the arm. Then these wrist and hand are driven. The mechanism 28 contains a nut 34 which has a linear motion by means of a key 32 and a rotary shaft 36 which engages the nut 34. The wire 26 is shifted in the circumferential direction to the wire 22 and connected between the plate 20 and the nut 34. Thus the shaft 36 can be revolved assuredly with no tilt of the nut 34 despite the difference of contraction factor produced between the wire 22.

Title: Pwm inverter equipment
Inventor: YASUDA TAKASHI
IPC: H02M7/48
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To prevent a backward operation regardless of a power factor angles between the output voltage and the output current by keeping a connection between two sets of serially connected capacitors which divide the input DC voltage at the same potential, in a PWM inverter wherein the output voltage pulse is composed of three potentials. SOLUTION: Using an exciting current command Id* and a torque current command Iq* generated by a current command generating means 1, a voltage command V* and a fundamental frequency command Fi* of the output voltage are found by a vector control system 2. Then, a pulse pattern for controlling the switching of a three-level inverter 5 is generated by a PWM controlling means. A pulse pattern correction calculating means 32 sets a factor in accordance with the torque current command Iq* and multiplies it by ΔVc which is a voltage difference between capacitors 7, 8 serially connected to the input side of the three-level inverter 5, to find Δαu'-Δαw' and gives them signs according to a phase region.  By this method, the factor for finding a quantity of correction for the pulse pattern for voltage control at a neutral point can be made smaller as torque current becomes smaller and a power factor comes near to 90 deg., and thereby a backward operation can be prevented.

Filed: 1992-09-18
Abstract: PURPOSE:To make it possible to control data transfer among optional I/O control devices by selecting and allocating a channel for controlling data transfer to a certain I/O controller at the time of generating a data transfer request from the I/O controller to a main storage device. CONSTITUTION:Direct memory access type data transfer between the main storage device 200 and plural I/O controller 300 is executed through the previously determined number of channels.

Filed: 1990-09-20
Abstract: PURPOSE:To improve spalling resistance, slagging resistance and slag permeating resistance by incorporating olivine source material in a specified range into the material to be poured essentially comprising magnesia. CONSTITUTION:This monolithic refractory material is prepared by compounding magnesia and olivine with the proportion of magnesia/olivine (M/O) from 9/1 to 1/9 for the <=1mm grain size and 9/1 to 1/9 for >1mm grain size. By specifing the proportion as above, a preferable structure is obtained with proper constitution in the matrix part in which the grain size constitution of the basic material is controlled to eliminate slaking and the purpose can be realized. These effects can be obtained by compounding olivine of <=1mm grain size by <=9/1 M/O, however, with a larger M/O than this, the obtd. material is almost same as a conventional magnesia material. With <=9/1 M/O, slag resistance is significantly decreased. As for >1mm grain size, with <=9/1 M/O, good spalling resistance can be obtained, however, with larger M/O than this, the material is almost same as single magnesia. With <=1/9 M/O, slag resistance is significantly decreased same as for the fine grain component.
