摘要:
An automatic programming apparatus is provided to generate a NC program for processing a roll having a cylindrical part and axle parts. The apparatus includes a roll-profile setting module, a process-condition setting module, a process-order setting module and an automatic programming module. The roll-profile setting module establishes dimensional values of the roll between an operator and the apparatus at every locational code, while the process-condition setting module establishes a plurality of process conditions at every process code, interactively. The process-order setting module combines the locational codes with the process codes at every process order, optionally and interactively, so that the process order of the cylindrical part and the axle parts is set while allocating any one of the process conditions. The automatic programming module generates the NC program for executing a series of roll process, on the basis of the combination of the process code and the locational code set by the process-order setting module.

The invention is a cellulose derivative wherein some of the carboxyl groups of the cellulose derivative carboxymethylcellulose are replaced with —CO—NH—X—CO—Y—Z, and a hydrogel of the same. In the formula, X is a C1-10 divalent hydrocarbon group, Y is a divalent group derived from polyalkylene oxide having oxygen atoms at both ends, and Z is a C1-24 hydrocarbon group or —CO—R4, where R4 is a C1-23 hydrocarbon group. The hydrogel has excellent viscoelasticity and can be injected into prescribed sites with injecting devices such as syringes, and it can thus be utilized as a medical gel or adhesion barrier.

A semiconductor integrated circuit includes a local memory permitting high-speed access. The local memory has at least first and second ports. The first port of the local memory is connected to a CPU by a first bus and the second port of the local memory is connected to an access control unit by a second bus. An external device is connected to the access control unit. When the CPU and/or the external device accesses the local memory, the CPU sends a control signal and data to the first port (CPU-access port) of the local memory via the first bus, and the access control unit sends another control signal and data to the second port (external-device-access port) of the local memory via the second bus. The local memory then executes data writing or reading based on the control signal(s) and data thus introduced to the access port(s). The external device can access the local memory via the access control unit to transfer data at high speed to and from the local memory.

A memory circuit includes a plurality of word lines connected to a plurality of memory cells, a plurality of row address decode circuits having address input terminals, a first wafer burn-in signal terminal, and a second wafer burn-in signal terminal. The row address decode circuits activate all of the word lines when the first wafer burn-in signal and the second wafer burn-in signal are in an enable state. On the other hand, the row address decode circuits activate a subset of the word lines when the second wafer burn-in signal is in the enable state.

A clock distributor circuit is provided which works with power consumption reduced in semiconductor logic circuitry including clock synchronous circuits. The clock distributor circuit includes clock generation circuits generating gated clock signals in response to a clock enable signal to supply clock synchronous circuits with the generated clock signals. It is thus possible to reduce the power that would otherwise consumed by the toggling of the clock signal. A clock distribution method therefore is also provided.

A dual port RAM includes an any-time readable/writable memory block in which an access can be made to the same storage area from independent first and second ports. In addition, the RAM includes a first test circuit for performing a test to the storage area of the memory block via the first port on the basis of a first clock signal, and a second test circuit for performing a test to the storage area of the memory block via the second port on the basis of a second clock signal. A control circuit of the RAM causes the first and second test circuits to test the memory block in an alternating manner.
