摘要:
An optical disk comprising two layers including a signal recording layer and an image recording layer further comprises a metal reflective layer formed on a surface of the image recording layer on the incidence side of laser light. The image recording layer is capable of forming a visible image in response to an increase in temperature caused by application of laser light to the metal reflective layer. The visible image is capable of being visually observed from a side opposite to the incidence side.

Wells of n- and p-type are formed in a p-type substrate. Wells of p-type are also formed in the n-type well. Both the p-type wells are formed by the same process at the same time to make MOS transistors have different threshold voltages. MOS transistors having a long gate length and a low threshold voltage are formed in the p-well in the n-well, and MOS transistors having a short gate length and a high threshold voltage are formed in the p-well at the outside of the n-well. Fuses are formed over the p-type wells in the n-type well at a high density.

There are provided a semiconductor device which can prevent short-circuit of the contact plugs and prevent exposure of wirings to ensure sufficient reliability even if level difference is caused in device isolation regions, and a method of manufacturing the same. Device isolation regions 13 are formed on a semiconductor substrate 11 to partition the semiconductor substrate 11 into a plurality of device regions 12. Then, word lines 14 are formed on the semiconductor substrate 11, and then peripheral regions of the word lines 14 are covered with a protection film. Then, impurity diffusion regions formed in the device regions 12, and then a plug insulating film is formed on an overall upper surface of the substrate 11. Then, opening portions 18a for connecting end portions of the device regions 12 are formed in the plug insulating film. Then, a conductive film is buried in the opening portions 18a, and then the conductive film and the plug insulating film are polished by the CMP method until any one of the protection film on the device isolation regions 13 and the protection film on the device regions 12 is exposed.
摘要:
A gas chromatograph for operation in split mode is controlled by calculating the column flow rate and the total carrier gas flow rate from the length and inner diameter of the column and specified values for temperature and column inlet pressure, adjusting the split flow rate such that the pressure value measured by a pressure sensor becomes equal to the specified pressure value and control the total carrier flow rate to be equal to the calculated value therefor. In this manner, the split ratio of the gas chromatograph can be maintained easily at a specified value. The amount of carrier gas to be wasted can be significantly reduced by appropriately varying the split ratio with time during the course of an analysis.

摘要:
A gas chromatograph has a control unit which normally carries out a pressure control so as to keep the pressure inside the vaporization chamber at a specified target level while the flow rate of a carrier gas into the vaporization chamber is kept constant. When a liquid sample is injected to cause a sudden rise in the pressure, the normal pressure control is temporarily stopped, say, for keeping the split ratio unchanged. In order to keep unchanged the retention time for components being analyzed although the pressure inside the vaporization chamber rises, the target value for the pressure control is reduced for an appropriate length of time after the temporary stopping of pressure control is discontinued.
摘要:
A gas chromatograph for operation selectably in both split mode and splitless wide bore injection mode includes a capillary column, a sample injection chamber at the inlet of the column, a three-way valve, a first piping line connected between one of the two outlets of the three-way valve and the sample injection chamber, a split line connected to the sample injection chamber immediately upstream of the inlet of the column for discharging therethrough a portion of a gas being sent out from the sample injection chamber, a second piping line connected between the other of the outlets of the three-way valve and the split line, and a third piping line connected between the first and second piping lines. By properly controlling the total carrier gas flow rate and the column inlet pressure, the split ratio can be controlled easily. By varying the split ratio appropriately during an analysis, the amount of the carrier gas to be wasted in the case of a split mode of operation can be significantly reduced.
