A phase difference measuring apparatus obtains a first receive signal by transmitting and receiving a to-be-measured material in a reference state and a second receive signal by transmitting and receiving a signal wave to and from that material in a measured state. The apparatus finds a reference phase difference .theta..sub.1 from the transmit wave and first receive signal and an apparent phase difference .theta..sub.2 ' from the transmit wave and second receive signal. The apparatus adds the apparent phase difference .theta..sub.2 ' to a product of the number of rotations, n, the apparent phase difference .theta..sub.2 ' passes through a given reference point and an angle of 360.degree. to find a true phase difference .theta..sub.2. The apparatus varies the number of rotations, n, to n+1 when the apparent phase difference .theta..sub.2 ', while being increased, passes through the reference point and that number of rotations, n, to n=n-1 when the apparent phase difference .theta..sub.2 ', while being decreased, passes through the reference point.

A semiconductor memory device has an address translator and a comparator. An entry of the address translator includes an associative memory cell array for storing and comparing a logical address of at least m bits. A first decoder generates a first word signal for the associative memory cell array. A first random access memory cell array stores a physical address of m bits. A controller generates a word signal for the first random access memory cell according to the first word signal and a result of a comparison by the associative memory cell array. A second random access memory cell stores a physical address of m bits. The second random access memory cell is physically disposed near the first random access memory cell array. A second decoder generates a second word signal for the second random access memory cell array. Outputs of the first and second random access memory cell arrays are connected to and compared by the comparator which outputs a signal upon coincidence between the outputs of the first and second random access memory cell arrays.

An instruction supplier for a microprocessor prevents a functional error operation of the microprocessor. In the instruction supplier, an instruction register temporarily stores an inputted instruction therein, and an instruction memory stores at least one instruction therein. At least one comparator is provided for detecting whether or not at least one instruction stored in the instruction memory agrees with the instruction stored in the instruction register, respectively, by comparing them, and for outputting a comparison result signal for indicating the comparison result. Furthermore, an instruction generator generates at least one specific instruction in accordance with the comparison signal, and then, an instruction selector selects either one of the instruction stored in the instruction register and the specific instruction generated by the instruction generator to be executed, and outputs the selected instruction.

A cache memory device including first and second address selectors and a control device for controlling the selection of two addresses out of four types of addresses. The four address types are instructions addresses successively generated by an increment of a program counter, a branch address for instruction fetch in a branch target based on a conditional branch instruction or the like, a data address for data access based on load instruction or store instruction, and a physical address for regulating data consistency between the cache memory device and other memory devices. A first memory array for storing tag addresses and a second memory array for storing instructions and data have two ports to access two selected addresses received from the first and second address selectors independently. Accordingly, access penalties by an RISC microprocessor are reduced in a processor unit in a multiprocessor system.

A memory unit includes an array of memory cells. Word lines are connected to the memory cells. Bit lines are connected to the memory cells. A decoder receives an address signal at a timing which follows an occurrence of a clock signal by a given time t1. The address signal is in synchronism with the clock signal. The clock signal has a preset period t0. The decoder decodes the address signal into a word signal and outputs the word signal at a timing which follows the reception of the address signal by a given time t2. A delay device delays the clock signal by a preset time "t" and thereby converts the clock signal into a control signal. An access to a word of the memory cells is performed via one of the word lines in accordance with the word signal at a timing determined by the control signal. The bit lines are precharged at a timing determined by the control signal. The preset time "t" is longer than a sum of the time t1 and t2 but shorter than a half of the period t0.

The present invention provides compositions and methods for use in enzyme replacement therapy. The inventors disclose a method of producing membrane bound enzymes in an active soluble form by eliminating the glycosylphosphatidylinositol (GPI) membrane anchor. In particular the inventors disclose a soluble active form of the membrane bound enzyme TNSALP which they produced by deleting the GPI anchor single peptide sequence. They have further shown that this composition is useful for treatment of hypophosphatasia. The inventors also disclose oligo acid amino acid variants thereof which specifically target bone tissue.
