Abstract: A loop control apparatus for controlling general process control such as control of the temperature of water supply comprises an interpreter for interpreting input information in the form of trains of characters to provide instrument information and a compiler for interpreting the train of character and compiling therefrom operational equation information. The trains of characters are inputted from an external general purpose computer as a man-machine interface through a serial interface provided within the loop control apparatus, and are subjected to word analysis and syntax analysis by the interpreter and the compiler. Loop control function information produced through the word and syntax analysis is stored into a memory means. Once the instrument design and the operational design have been completed, the interface computer is not needed and can thus be used for other jobs not related to the system under control.

Abstract: A wiring connection terminal block having a housing for accommodating a movable block and a compression spring, is arranged within an insulator made of fire-proof synthethic polyester. Two opposite sides of the housing each has a wire hole with oblique surface, forming a sharp wedge at the top rim of each hole. The moveable block has a wire hole with oblique surfaces forming concavities into opposite surfaces of the moveable block. The oblique surfaces are positioned at the bottom rims of the wire holes on the surface of the moveable block and extend into the moveable block. A wire is inserted into the wiring holes by compressing the compressing spring to bring the wiring holes of the moveable block into alignment with the wiring holes of the housing. When the compressing spring is released an inserted wire is pushed upward and bent into the concavities on either side of the moveable block by the force of the compressing spring.

Abstract: In a memory cell comprising a data cell array and a parity cell array, an error checking.multidot.correcting circuit is connected to each of the arrays through a selector. The selector is constituted by transistors connected to each of the bit lines in the memory cell. The number of circuit elements constituting the error checking.multidot.correcting circuit corresponds to one-half of the number of the bit line pairs included in the data cell array and the parity cell array. In an error correcting mode, half of the data appeared on the bit line pairs in data cell array and the parity cell array are transferred to the error checking.multidot.correcting circuit by the selector, so that the errors are corrected. Thereafter, the data of the remaining half of the bit line pairs are processed in the same manner. Therefore, the number of circuit elements of the error checking.multidot.correcting circuit can be reduced compared with the prior art, improving the degree of integration of the device.

Abstract: A vibration control system for generating desired random vibration environment with a given reference Power Spectral Density (P.S.D.) using a vibration generator on which a test object is fixed is disclosed. A detected signal representing vibration of a test object is converted into a response spectrum by Fast Fourier Transform (FFT) and the response spectrum is compared with the reference spectrum to determine a drive spectrum. Random drive signal having the determined drive spectrum amplitude is then generated continuously, and the signal is applied to a vibration generator on which the test object is fixed. This signal must be random i.e. nonperiodic, and therefore consisting of continuous spectral components with sufficient statistical independence. Method and facility to generate above mentioned signal are the principal of the present invention.

After the elongated rod is loosely inserted into the retaining portions of said hook members with a predetermined play, the wedge-like members mounted on the elongated rod are forcibly inserted into interstices formed between the loosely fitted rod and hook members, to thereby firmly fix the hook members with the elongated rod.

Abstract: A system and method for automatically controlling a vehicle speed to a desired cruise speed are disclosed in which when the vehicle speed is reduced by a first predetermined value from a set and stored cruise speed at which the vehicle is cruising during the operation of the automatic cruise control, the gear range of a vehicular transmission is shifted down and simultaneously the set and stored cruise speed is updated to reduce the set and stored cruise speed by a second predetermined value so that the vehicle speed coincides with the updated cruise speed. In addition, after a predetermined time has elapsed, the gear range is shifted up and the updated cruise speed is returned to the original cruise speed.

Abstract: This invention relates to improvements in a resilient leg brace which acts in parallel with a runner's legs to support his or her weight during foot impact, to store the kinetic energy of vertical motion, and to release said energy thrusting the runner back into the air during take-off. The running brace is energy efficient in that it stores and releases the maximum amount of vertical kinetic energy so that the leg muscles do not need to supply as much energy to lift the runner's weight during each step. The running brace also protects the legs and other parts of the body from impact damage. The leg brace is attached to a pelvic harness, and optional back and neck braces are attached to the shoulders and the chin to protect the back and neck from impact shock. The first improvement relates to an asymmetric travel structure which enables the running brace to deliver an upward thrust over a greater distance than that required to absorb the runner's downward impact.
