Abstract:
An outer pipe is diametrically expanded by heating and an inner pipe is diametrically contracted by cooling with a coolant introduced into the inner pipe to produce between the pipes a clearance just sufficient for insertion of the inner pipe into the outer pipe, and then the coolant is pressurized to expand the inner pipe against and together with the outer pipe, the pressure being removed after the pipes have expanded to a specific diameter of the joint therebetween. The tightness of the fit between the pipes due to the expansion is further increased by the subsequent thermal shrinkage of the outer pipe and thermal expansion of the inner pipe.
Abstract:
A flux composition for ceramic color, containing no harmful heavy metal such as lead, cadmium, chromium, etc. is provided.The flux composition consists mainly of 30 to 45% of SiO.sub.2, 0 to 5% of TiO.sub.2, 4 to 10% of ZrO.sub.2, 13 to 18% of B.sub.2 O.sub.3, 18 to 23% of ZnO, 0 to 3% of CaO, 12 to 15% of the total of two or three kinds of R.sub.2 O selected from Na.sub.2 O, K.sub.2 O and Li.sub.2 O, 4 to 10% of fluorine and 0 to 5% of tin oxide (% being all by weight).The composition uses no lead which has been indispensable for lower melting glasses, and exhibits superior performances difficult to afford according to conventional lower melting lead-free fluxes.
Abstract:
At least one ship building berth space is provided on the ground adjacent to a dock facing open water. When a ship is built in the berth space, temporary partitioning walls are set up in a manner surrounding the berth space and the dock, and water is supplied into the area surrounded by the walls to cause the ship to float off the floor of the berth space, whereby the ship can be floatingly moved into the dock and then can be launched into the open water.
Abstract:
An emergency wireless connection system which operates as a normal information terminal in normal times and operates as a terminal to send and receive emergency information in emergency situation includes a line detection unit which detects an emergency communication network capable of communicating when emergency situation occurs, and a control unit which makes the emergency wireless connection system conform to a procedure of the emergency communication network based on channel information of the emergency communication network detected by the line detection unit.
Abstract:
A processing apparatus comprising a register that stores operand data, a register data reading section that reads operand data stored in the register, a coefficient table set storage section that stores a coefficient table storing Taylor series operation coefficient data, a coefficient data reading section that reads the Taylor series coefficient data from the coefficient table set storage section using the degree information of the Taylor series and the coefficient table identification information and a floating point multiply-adder that executes the Taylor series operation using the coefficient data read by the coefficient data reading section, data read from the register.
Abstract:
A cache memory having a sector function, operating in accordance with a set associative system, and performing a cache operation to replace data in a cache block in the cache way corresponding to a replacement cache way determined upon an occurrence of a cache miss comprises: storing sector ID information in association with each of the cache ways in the cache block specified by a memory access request; determining, upon the occurrence of the cache miss, replacement way candidates, in accordance with sector ID information attached to the memory access request and the stored sector ID information; selecting and outputting a replacement way from the replacement way candidates; and updating the stored sector ID information in association with each of the cache ways in the cache block specified by the memory access request, to the sector ID information attached to the memory access request.
Abstract:
Multiple data processing instructions instruct a computing device to process multiple data including first data and second data. When a multiple data processing instruction is decoded, two allocatable registers are selected. One is used to store the result of a processing operation performed on first data by one processing unit, and the other is used to store the result of a processing operation performed on second data by another processing unit. Those stored processing results are then transferred to result registers. Normal data processing instructions, on the other hand, instruct a processing operation on third data. When a normal data processing instruction is decoded, one allocatable register is selected and used to store the result of processing that a processing unit performs on the third data. The stored processing result is then transferred to a result register.
Abstract:
A single-precision floating-point data storing method for use in a processor including a register, which has a size that can store double-precision floating-point data, for storing double-precision floating-point data and single-precision floating-point data comprises writing input single-precision floating-point data to the high-order half of the register, and writing all zeros to the low-order half of the register if a single-precision floating-point data process is specified.
