摘要:
A semiconductor device has p-channel field effect transistors disposed in a lattice shape. In order to generate compression stress in the channel of a p-channel field effect transistor, a long active region of a plurality of transistors is divided for each gate electrode and a sufficiently thin shallow trench isolation (STI) is formed between adjacent gate electrodes. The drain current characteristics can be improved.

A data processor comprises a plurality of registers 1 (registers a to d), a plurality of data saving stack memory devices 2 coupled to the registers 1 for exclusive use thereof, respectively, and an instruction decoder for decoding instructions for controlling the registers 1 and the data saving stack memory devices 2 in accordance with the result of the instruction decoding. In response to an instruction "PUSH", the contents of the registers 1 (registers a to d) are selectively saved to the data saving stack memory device 2. In response to a instruction "POP", the contents of the data saving stack memory devices 2 are selectively restored to the registers 1 (registers a to d). Each of the instructions "PUSH" and "POP" has a field for indicating need or needlessness of the saving and restoration for each of the registers 1 and each of the data saving memories 2.
摘要:
In a method for separating a hydrocarbon mixture into relatively difficultly soluble hydrocarbons and relatively easily soluble hydrocarbons by extractive distillation using a polar solvent comprising feeding the starting hydrocarbon mixture to at least two evaporators, an extractive distillation column, a stripping column and a rectifying column; the improvement wherein(1) the polar solvent discharged at a high temperature from the bottom of the stripping column is recycled to the extractive distillation column after it has been cooled to a suitable temperature by giving up heat to a reboiler of the extractive distillation column, a reboiler of the rectifying column and successively to the two or more evaporators, and(2) the starting hydrocarbon mixture is divided into two or more streams and heated in two or more evaporators, one stream being evaporated in a first evaporator to a pressure necessary for introduction into the extractive distillation column and then fed to the extractive distillation column, and the other stream, after evaporation in a second and subsequent evaporators, being pressurized to a pressure required for introduction into the extractive distillation column by means of a compressor and then fed into the extractive distillation column.

Amusement equipment can be easily installed in a building at low cost. Also, desired amusement equipment can be renewed easily and at low cost. In a building, an amusement facility is provided by installing a container provided therein with amusement equipment. The building is formed with an opening portion for carrying-in-and-out the container therethrough. A container supporting portion for permitting carrying-in-and-out the container is provided in the building. Accordingly, the container is placed on the container supporting portion through the opening portion to install the amusement equipment in the building. Also, by replacing the container in the building, the amusement equipment can be replaced.
摘要:
Source and drain regions are formed in first regions of low concentration formed on a surface of a semiconductor surface, and a second region with doping concentration higher than that of the first regions is formed around the first regions. Further in the second region, third regions with doping concentration higher than that of the second region are formed separate from each other. By virtue of this, a rise of the threshold voltage attendant on a decrease of the channel length is canceled out by the third regions and the short channel effect is suppressed. Further, since doping concentration of the first region is low, high carrier mobility can be obtained.

The invention provides porous particles, a process for producing the porous particles, and cosmetics comprising the porous particles. The porous particles of the invention have an average particle diameter of 75 μm or less, based on polyethylene resin having a crystallization degree of 70% or more. The porous particles further comprise an active ingredient. The process for producing the porous particles, comprises mixing polyethylene resin having a crystallization degree of 70% or more, and a low-molecular weight compound having a melting point lower than the softening temperature (or melting point) of the polyethylene resin, with each other at a temperature not lower than the softening temperature (or melting point) of the polyethylene resin, then spraying the mixture into a gaseous phase or a solvent at a temperature at which the viscosity of the mixture becomes 600 mPa·s or less, and removing the low-molecular weight compound from the resulting particles.
